Title: Paper-like elements
Inventor: MULLER FRIEDHELM
IPC: C08J9/33
Filed: 1963-08-01
Abstract: Paper-like flat elements are prepared by comminuting polyurethane foam in an aqueous medium, mixing the comminuted polyurethane with beaten pulp or cellulose derivative or fibrous synthetic polymeric material and forming a web from the mixture on a paper-making machine.  The pieces of polyurethan foam may be comminuted by beating them in a hollander.  Fibres of natural cellulose, regenerated cellulose, cellulose acetate or synthetic polymers such as polyacrylonitrile, polyamides or polyesters, cut short, are beaten separately and added to the beaten polyurethane, or may be beaten with the polyurethane. A non-foaming surface-active substance may be added to the polyurethane in the beater or to the mixed pulp.  A binder or a wet-strengthening agent may be added to the pulp.  The surfaceactive substance may be a mixture of paraffinic hydrocarbons and polyglycol oleate.  Wetstrengthening resins may be condensates of polyalkylenepolyamines and epichlorohydrin, melamine-formaldehyde or urea-formaldehyde resins.  Binders may be natural or synthetic latices, e.g. of a copolymer of butadiene, acrylonitrile and methacrylic acid, or polychlorobutadiene. The formed sheets can be impregnated with natural or synthetic latices. The products have good heat-insulating and sound-damping properties, and can be used for packaging, as insulating layers, as carpet underlays or as window-leathers.ALSO:Paper-like flat elements are prepared by comminuting polyurethane foam in an aqueous medium, mixing the comminuted polyurethane with beaten pulp or cellulose derivative or fibrous synthetic polymeric material and forming a web from the mixture on a paper-making machine.

Title: Apparatus and method for collecting flexible sheets
IPC: B65H29/14
Filed: 1963-08-02
Abstract: 1,034,477. Delivering sheets. A. R. STOBB. Aug. 2, 1963, No. 30663/63. Heading B6H. A method of stacking sheets on a receiver comprises dropping the sheets in an overlapping fashion on a conveyer which moves the sheets from a position below the receiver to an inverted position above the receiver and then directs the sheets downwardly on to the receiver, stripping the sheets from the conveyer, and finally forming the sheets into a stack on the receiver. The overlapping stream of sheets 13 is delivered from a printing press by four spaced endless belts 27. The outer belts return directly to the press via pulleys 19. The centre two belts pass around two spaced drums 17 and return to the press via pulleys 22 and 19. Two additional belts 13 passing around the drums 17 and pulleys 51, co-operate with the centre two belts 27 to convey the sheets around the drums 17 and deposit them on the receiver 16. The drums 17 are freely rotatable on a driven shaft 32. The pulleys 51 are keyed to a shaft 49 driven from the shaft 32. Said shaft 49 is carried by spaced arms 37 supported from the shaft 32 by ball races. The arms 37 also carry a plate 47 and are oscillated by a constantly rotating member 39 engaging oval-shaped openings 44 in the arms. The reciprocating plate 47 pushes the stack up the plate 16 to permit delivery of the sheets to the bottom of the stack. The marginal edges of the sheets extend beyond the belts 13 so that they are bowed transversely to stiffen them. The rear edges of the sheets are stripped from the belts 13 by a rotary brush 82. The receiver is recessed at 52 to receive the plate 47 and adjustable normally to its plane by screws 77. The platform is guided during adjustment by bars 79 welded to the side plates 10 of the machine which engage notches in the side edges of said receiver.

Title: Improvements in or relating to gyratory crushers
IPC: B02C2/04
Filed: 1962-08-15
Abstract: 1,019,304. Gyratory crushers. NORDBERG MANUFACTURING CO. Aug. 15, 1962 [Aug. 15, 1961], No. 31350/62. Heading B2A. [Also in Division Fl] A gyratory crusher, having a normally stationary crushing member 22 which is screwthreaded into a supporting ring 14 yieldably held on the main frame 10, is provided with fluid-operated piston-and-cylinder assemblies 34 arranged near the upper portion of the member to apply an upward thrust to the latter to take up the slack between the screw threads. The assemblies 34 are mounted on a cap 29 which is arranged to be stepped round by a pair of fluid-operated rams which are mounted one on each side of the crusher on the ring 14 for engagement with a toothed flange 62 of the cap. The cap and member 22 are locked together by projections 31a, 36 so that they rotate together and allow vertical movement of the member 22 within the cap. When the member 22 is to be lowered to compensate for wear of its liner 24 which is of manganese steel, the fluid pressure to the assemblies 34 is released and then the side rams operated to screw down the member 22; the member 22 may be locked in the adjusted position by fluid-operated locking devices carried by the ring 14 and operated to engage the flange 62. Fluid is then supplied to the assemblies 34, Fig. 3 (not shown), to effect upward thrust of each rod 68 which is connected to the flange 31 of the member 22 by a collar 82 and key 85. The rod is resiliently connected at its upper end to a sleeve 72 which is arranged to move with the rod when acted upon by a loosely mounted piston 78. When uncrushable material enters the crusher, the spring assemblies 16 allow the member 22 to lift, the fluid system being protected against damage due to abnormal pressures during these conditions by the springs 76 as shown or alternatively, by accumulators disposed adjacent the ports 65 of the assemblies 34.
