The invention relates to a device of the type adapted to deliver fluids, notably medicaments, under pressure. The device comprises a container 1 of variable volume in the form or shape of a pouch or flexible receptacle of generally cylindrical shape with longitudinal pleats 2 containing the fluid under pressure to be delivered and equipped with an actuator C permitting to open a valve 15 a , 15 b to enable the delivery of said fluid, the whole being located inside a container 4 capable of resisting to an elevated internal pressure, the internal volume of the latter container comprised between its wall and the container of variable volume being filled with a neutral gas under a pressure sufficient to exert on the container of variable volume a pneumatic constraint sufficient to permit the delivery of the therein contained fluid when the above-said valve permitting said delivery is operated by the aforementioned actuator C.

A manually-actuated device for the deliver of a volume of liquid which includes an outlet through which liquid is in use delivered and a cover member which is movably disposed relative to the housing between a first position in which the cover member at least partly covers the outlet and a second position in which the cover member acts as a lever which in use is acted upon by a user to actuate the delivery device.

The present invention concerns a means for controlling and/or measuring the flow of a running fluid, wherein the throttling of the flow is controlled utilizing the fluid's own differential pressure arising from the flow. The valve comprises a cover provided with a flow aperture, a main valve disc and control means consisting of a cylinder volume/piston assembly, the movement of said piston being connected to the main valve disc, and wherein the cylinder volume has been connected by a first opening (d1 min ) to the high pressure side and by a second opening (d2 min ) to the low pressure side so that the ratio of the areas of the openings is adjustable. The means comprises at least one sensing member by the aid of which the position of a part of the cylinder volume/piston assembly moving axially in the direction of the flow is measured; a data processing unit, to which the signal from the sensing member is conveyed after appropriate processing; a memory unit, in the first part of which have been stored data concerning the characteristic curve of the valve or equivalent, from which based on the signal from said sensing element, with the aid of the data processing unit, the variations of volumetric flow and or pressure can be calculated, and in the second part of said memory unit being stored the desired values of the volumetric flow and/or pressure, with which the calculated values mentioned before are compared; and at least one actuator by the aid of which the ratio of areas of the openings (d1 min , d2 min ) is adjustable for realizing the desired volumetric flow and/or pressure.

Equipment (10) for the preparation of a hot beverage comprising a boiler (10) capable of containing a liquid component of the beverage, for example water, a collection container (14) and means (22, 20, 28) defining a delivery path for the liquid component from the boiler to the collection container. The equipment also comprises valve means (40) located along the delivery path for the liquid component comprising a plug (44) which can move between a position in which the delivery path is closed and one in which it is open and means (70, 72; 74, 76; 78) to immobilise the plug in the open position. These means are arranged in such a way that they can be activated and deactivated by a force exerted in the direction of movement of the plug.

A method and a device for applying a filler-containing plastics layer to even a shaped surface, in which a mixture containing a binder or a binder mixture and a filler is sprayed onto the surface, a free jet for application by spraying first being generated from a binder or binder mixture and the filler then being added to the free jet of the not yet polymerized binder or binder mixture. The method is particularly suitable for the spray application of heavy layers such as those used in conventional mass-spring systems.

A bulk material processing apparatus (10) which comprises: a longitudinally extending main frame (11); a supply conveyor (23) mounted on, and extending lengthwise of the main frame (11), and operative to convey a supply of bulk material from a forward lower end of the conveyor to an upper and rearward discharge end (24); a material processing device (13) mounted on the main frame (11) and arranged to receive material from the discharge end (24) of the supply conveyor (23), to process the material, and to discharge processed material; a discharge conveyor (32) mounted on the main frame (11) below the processing device (16) so as to be able to receive processed material discharged by the processing device, and to discharge the material to a discharge point located rearwardly of the apparatus; means (16, 17, 18) mounting the processing device (13) on the main frame (11) for movement between a raised operating position to a lowered transport position; and, means (34) mounting the discharge conveyor (32) on the main frame (11) for movement between a raised operative position and a lowered inoperative position; in which the discharge conveyor (32) has a first part (32a) which is mounted on the main frame, and a second part (32b) which is adjustable between an operative position in which it forms a prolongation of the first part, and a folded transport position in which it extends below the first part.
