A device for preparing and ejecting polymeric cement made from at least two pre-packaged components comprises a tubular vessel including a first axial end wall having a closed outlet, and a second axial end wall having an aperture. A first starting component of the polymeric cement is present inside said tubular vessel near the first axial end wall. A hollow shaft extends through said aperture of the second axial end wall. A piston element comprises a closed container filled with a second starting component of the polymeric cement. The piston element is selectively lockable to the shaft. The container has a bore and is slidingly engaged upon said shaft. An agitator element is secured to one end of the shaft. Furthermore opening means for providing an opening in the closed container are provided. The hollow shaft is provided with a gas permeable filter means.

u The device comprises a store (5) for connection elements (4), a transfer arrangement (7) for transferring the connection element from the store to a pressing assembly (8, 13, 14). There may be an arrangement of counter-layers opposite the pressing assembly and one or more magazines (6) for receiving and intermediate layering from the store of connection elements to the transfer arrangement. The arrangement for the magazine may be on the longitudinal side of a transport system (1, 2) for the technical wooden product (3) above or below the transport plane of the wooden product. The store may be made up of a discharge, sorting, aligning and conveying system for pre-fabricated connection element to the transfer arrangement.

A frame structure consisting of two compound units provided with mutually facing grooves undercut on either side, in which the first compound unit can be attached in a desired position to the second compound unit via a detachable coupling which comprises a turning part which can be turned from the outside manually via a handle about its longitudinal axis by about 90 DEG into its coupling or decoupling position, and which in its coupling position positively engages by means of a T-head at its one end in one of the two grooves and by means of anchoring means at its other end in the other of the two grooves and can be locked in this coupling position by means of an anti-rotation device. To connect the two compound units to each other without special tools, but above all to be able also to detach them from each other again, it is proposed according to the invention that the anchoring means comprise a punched part which is arranged longitudinally displaceably in the one groove and bears the turning part which is freely rotatable relative to it and that the handle comprise a resilient element connected securely against rotation to the turning part, which element in decoupling position extends in relieved state or under only slight stress between the two compound units and in coupling position engages under bending stress behind a holder.

This invention relates to a module for the wall-mounting of a terminal (13) of an air conditioning system which has the characteristic of comprising a structure (4, 25) which can be embedded into a wall (1) forming a space (2). The structure (4, 25) removably houses the terminal (13) in such a way as to form the said space (2) in accordance with good practice and such as to ensure a correct surface finish in the vicinity of the perimetral edge (2A) of the said space (2).

The present invention concerns a device for securing an insulation board within a cavity wall, comprising an inner wall, an outer wall and a cavity in between said inner and outer walls in which insulation boards are accommodated, said device comprising: wall anchor means (5) for securing the inner wall to the outer wall; retaining means (7,7') for fixating an insulation board in the cavity; said retaining means including projections (7) gripping an end portion of the insulation board; wherein the retaining means include a mounting element (6) adapted to be fastened to the inner wall; the anchor means comprises an elongated member (5) with holding means (13), which cooperate with corresponding receiving means (16) on the mounting element for securing the anchor member to the mounting element; and the projections (7) are formed in the mounting element. Hereby, a better insulation quality may be achieved as the insulation boards may be positioned against a smooth inner wall without any wall ties pre-mounted, on which the insulation panels otherwise could be damaged. The insulation mounting procedure becomes much simpler and easier by a device according to the present invention, saving a considerable amount of time and consequently labour costs.

A fitting for connecting two structural components. The fitting includes a locking device mounted on the first structural component and a support device mounted on the second structural component. A rotary member in the support device defines circumferentially extending conical surface against which the front end of the locking device is pressed when the two fitting devices are connected. The force exerted by the front end of the locking device causes the rotary member to be turned. The rotary member has a helical end face which is initially outside of the range of travel of the locking device. Upon turning of the rotary member, the helical end face comes into engagement with a countersurface of the locking device. The resulting connection can only be released by means of a tool. The structural components are pressed tightly together by a further turning of the rotary member. A piece of furniture composed of several structural components can be initially connected without the aid of a tool and can subsequently be tightened after the piece of furniture has been assembled. The fitting makes possible the connection of structural components where the tolerances in assembling the fitting devices are inaccurate or have been exceeded.

The module (40) consists of a holder for a container used e.g. in the preparation of food on a large scale. It is made from stainless steel tubing or rod, bent into shape and having its ends welded together to form a supporting base (41) and side walls (42, 43). Modules can be stacked on top of one another in a column, e.g. on a trolley, and separated for cleaning.

The invention relates to a composite material (1), for closure elements, mad from a support material (2) and a thermoplastically moulded layer (3) with projecting and recessed sections (4,5). According to the invention, the thermoplastically moulded layer (3) is thinner in the region of the recessed sections (4) than in the region of the projecting sections (5). Said surface structure may for example be produced by embossing by means of ribbed rollers or embossing plates. The composite material (1) is suitable for the production of sealing elements, such as for example, cup tops, usually stored in stacks. The cup elements stacked thus can easily be unstacked after stacking, precisely by means of said recessed or projecting sections(4, 5). On the side of the composite material facing the consumer a decorative and/or informative impression (6) can further be provided.

An extrusion apparatus having a barrel (3) and a rotatable threaded screw (1) coaxially positioned therein is disclosed. The apparatus includes an upstream inlet section having an opening (13) therein for receiving material to be processed by the apparatus, a compression section (2) downstream of the inlet section, and a mixing or plasticizing section (7/8) downstream of the compression section. The interior surface of the barrel is provided with an undercut (12) therein which intercommunicates the feed opening with the compression section and has a portion thereof which extends downstream in the compression section about the interior surface of the barrel with a continuously decreasing cross-sectional area. The undercut may be formed in a cylindrical insert (9), carried within the barrel and, in an alternate embodiment, a second undercut cylindrical insert positioned about the first insert and rotatable relative thereto may be employed to vary the cross-sectional area of the undercut.

The filling device includes an issuing funnel (12), filling tube (13), a conveyor screw (14) in the filling tube and connected to a rotary drive motor, and a height adjustable closer (16) at the lower end of the filling tube. The rotary drive motor, conveyor screw and closer are an adjustable in height relative to the filling tube.
