In a hair cutting device in which a head portion (1) is connected such that the head portion can laterally tilt and vertically move, the head portion is stably supported in a front-rear direction, and the number of parts is reduced. In a hair cutting device, the head portion for cutting hair is connected to an upper portion of a main body grip portion (2) such that the head portion can laterally tilt and vertically move, the head portion is resiliently biased upward. An upper end of the main body grip portion is formed with an opened space (26) into which an accommodating body (10c) having a motor (8) of a lower portion of the head portion is inserted. Front and back surfaces of the accommodating body have a pair of left and right shaft portions (70) which are connected to an inner surface (78) of an opened space of the main body grip portion such that the shaft portions can turn andverticallymove and come into contact with slide contact, and a contact portion (75) which is provided lower than the pair of shaft portions and which comes into slide contact with an inner surface of the opened space.

The invention concerns an apparatus for and a method of treating a plurality of zones of a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, wherein the treatment liquid is introduced into pipes conveying the carrier liquid to each zone as discrete slugs, and wherein the volume of each slug is selectively variable or wherein each slug may be introduced into the pipes at a selectively variable frequency. Preferably the treatment liquid is applied to all zones from a single source (1), and the slugs, upon discharge at least at one zone, remain substantially concentrated. The invention particularly concerns the lubricating of conveyors as on bottling lines.

The invention relates to a method for straightening a metal strip (1) which is guided in the direction of transportation (R) through a straightening machine (2) and is straightened. In the straightening device (2), the metal strip (1) is impinged upon by a straightening force (F) which is applied by a plurality of straightening rollers (3) in the direction (N) which is perpendicular to the surface of the metal strip (1). According to the invention, prior to the metal strip (1) entering into the straightening machine (2), the thickness (d) of the metal strip (1) is determined and the position (a) of the straightening rollers (3) in the direction (N) which is perpendicular to the surface of the metal strip (1) is taken into account according to the determined thickness (d).

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.

A method of manufacturing a composite, prestressed wooden beam (1, 10, 35, 67, 90) comprising the steps of: positioning a plurality of beam parts (2, 16, 68, 69) in contact with one another at least in one direction transverse of the direction of length, bending the beam parts (2, 16, 68, 69) into the desired shape and interconnecting the beam parts (2, 26, 68, 69). The number of beam parts (2, 16, 68, 69) positioned in mutual contact is bent integrally into the desired shape and retained. Subsequently the connection is performed by passing a great number of smooth, substantially cylindrical pins (6, 21, 61, 70, 72) through the beam parts (2, 16, 68, 69) in a direction transverse of the direction of length and subsequently the resultant composite beam (1, 35, 67, 90) is disengaged. Furthermore the invention relates to a device for manufacturing said composite, prestressed wooden beam (1, 10, 35, 67, 90) comprising a stationary, elongate gauge (11, 31). This device comprises a displaceable drilling device (17, 37) comprising a drill holder (26, 51) having a rotary shaft to be positioned transversely of the direction of length of the gauge (11, 31), a displaceable pressing device (22, 40) having a pressing stroke transverse of the direction of length of the gauge (11, 31) and supporting means (12, 24, 32, 91) for supporting the pressing device (22, 40) with respect to the gauge (11, 31).
