Title: Press pads for hydraulic presses
IPC: B27N3/20
Filed: 1968-01-17
Abstract: 1,212,591. Pressure equalizing device; finishing edges; laminated pad. THOMAS JOSEF HEIMBACH G.m.b.H. & CO. 17 Jan., 1968 [17 Jan., 1967], No. 2590/68. Headings B5A, B5F, B5K and B5N. A pressure equalizing device, for particular use in an hydraulic press, comprises a single fabric pad having a thickened marginal zone extending about the whole of its periphery or a plurality of pads each having a thickened marginal zone along part of its periphery, said zones, when the pads are superimposed in the correct orientation, giving a thickened zone around the whole of the area covered by the pads. The thickness of the or each marginal zone increases from its inner to its outer edge. Where more than one pad is used the pads may be scattered throughout the other press elements and material to be pressed. Each pad can be made of one or more layers of peripherally reinforced heat resistant fabric made from cotton, metal, synthetic, or, preferably, asbestos fibres, the thickening being produced either by clipping or adhering edge strips or by incorporating more or thicker fibres into the marginal regions. In the embodiments shown in the figure, one form of pad (top right and bottom left) consists of a woven asbestos fabric having lateral thicknened regions a and b, formed by incorporating extra threads and still more extra threads respectively, and longitudinal thickened regions formed by adhering extra fabric strips. As illustrated in the top left and bottom right corners, both longitudinal and lateral margins can be formed by incorporating extra threads which are'overlapped at the corners in various ways to prevent extra thickening. The pressure equalizing pad or pads may be used in the manufacture of hardboard, chipboard, or laminates, such as plywood.

Abstract: 124,020. Marks, E. C. R., (National Equipment Co.). Feb. 14, 1918. Depositing-machines.-Relates to confectionery - depositing machines, such as are described in Specification 17858/15, and comprises mechanism for feeding the starch trays to the depositor. The trays d are fed forward through a distance at least equal to their length by dogs h on chains g and are delivered to chains 10 which carry them step by step beneath the depositor nozzles c. The chains 10 are moved forward a distance equal to that between successive rows of mould depressions by a ratchet 14 and pawl 15, operated through a lever 16, link 17, and lever 18, from a crank 21. The lever 18 is provided with a slot 20 having a curvature equal to the length of the link 17, the end of which is adjustable therein to vary the throw of the pawl 15. To ensure accuracy of movement, the pawl may comprise a number of pawls 15<1>, Fig. 6, of different lengths. In order to bring the first row of moulds into alinement with the nozzles c, the trays are advanced independently of the chains 10 by bars 36, which engage behind them and are operated by levers 35, 29 connected by an adjustable link 30 to a curved slot 31 in a plate 32 secured to the lever 18. During the advance of the succeeding tray, the bars 36 reciprocate idly along the sides until they drop behind the rear wall of the tray.

Patent GB-673651-A (GB)
Title: New polymers
IPC: C08G61/02
Filed: 1949-02-07
Abstract: Polymers are produced by pyrolysing the vapour of p-xylene substituted in the nucleus by at least one atom of the normally gaseous halogens at a temperature between 700 DEG  and 1000 DEG  C. for not more than 10 seconds and cooling the resulting vapours so that a solid polymer is deposited.  Specified compounds which may be pyrolysed are 2-fluoro-, 2-chloro-and 2,5-dichloro-p-xylenes.  The preferred duration of pyrolysis is from 0.1 to 1 second.  The vapour pressure should not exceed atmospheric and the vapour may be diluted with an inert gas, e.g. nitrogen or carbon dioxide, to maintain a low partial vapour pressure of the compound.  Cooling may be effected by contacting a cool surface, e.g. at a temperature of 100 DEG  to - 80 DEG  C., on which the polymer is deposited as a film.  The monomeric unit appears to be the original compound with two CH2 groups instead of the two paramethyl groups. In the examples, the vapours at a pressure of 8 to 10 mm.  Hg. abs., are passed through a tube heated to 800 DEG  C.  The polymers are insoluble in many organic solvents, are heat-stable and resistant to corrosive liquids and have good heat and electrical insulating properties.  Specification 650,947 is referred to.ALSO:2 - Fluoro - p - xylylene di - iodide is prepared by reacting the vapour of 2-fluoro-p-xylene, pyrolysed at 700-1000 DEG C., with iodine vapour, and cooling the resultant vapours, when, in addition to the deposition of polymer (see Group IV (a)), white needles of the above compound having a melting point of 150-151 DEG C. are deposited.
