Abstract: 650,233. Endless-belt conveyers. CATTO, A. I., and MACCARTHY, C. P. Oct. 5, 1948, No. 25998. [Class 78 (i)] Supporting-means for conveyer idlers of the kind built-up of frame members adjustabliy attached to pairs of spaced upright and horezontal supporting tubes or rods comprises cross-frames of strip material, each provided with upstanding end walls apertured to receive the end of the idler spindles and with a depending flange and a pair of laterally-projecting portions at each end, said pairs of projecting portions each being key-hole slotted to engage one of a pair of spaced upright supporting tubes or rods, and a clamping bolt being mounted between said portions at each end of the crossframe, whereby a horizontal or vertical supporting tube or rod can be clamped against each of said upright tubes or rods. The Figures show cross-frames 10 which are adjustably attached to pairs of rods 24, 25 so as to support troughing idlers 17, 21 supporting both the upper and lower runs of a belt conveyer. The frames 10 are provided with end and intermediate walls 14, 15 and with depending flanges 11, each flange 11 being bent to form the lower of a pair of lateral portions 12,13, the upper lateral portion of each pair being integral with the wall 14. The walls 14 are slotted at 16 to receive the outer ends of the spindles of the lateral rollers 17 and the walls 15 are apertured at 18 to receive the inner ends of these rollers and are slotted at 19 and apertured at 20 to take the ends of the spindle of the roller 21. The portions 12, 13 are each provided with keyhole slots 22 to receive the rods 23, 25. The frames for the rollers supporting the lower conveyer run are carried by the rods 23 which are supported in sockets 28 on feet 29, and those for the rollers supporting the upper run are carried by the rods 24, the overlapping ends of these rods 23, 24 being fixed in the slots 22 of the lower cross-frames by bolts 26 carried by the flanges 11 of these frames.

Abstract: 743,846. Artificial teeth. JUSTI & SON, Inc., H. D. Oct. 17, 1952, No. 26108/52. Class 81(2). [Also in Group V] An artificial tooth is made by forming component parts of the tooth from a mixture of monomer and polymer and joining the parts by moulding (see Group V). The monomer may be methyl methacrylate, divinyl benzene, diethylene glycol methacrylate or styrene, and the polymer may be polyester, alkyd or allyl resin or polystyrene.

Title: Process for the manufacture of vinyl chloride polymers
IPC: C08F6/20
Filed: 1975-06-19
Abstract: Vinyl chloride homo, graft or co polymers comprising at least 80 % by weight of polymerised vinyl chloride are produced by polymerising the monomer(s) in aqueous emulsion or suspension in the presence or absence of polymers. The bulk of unconverted monomer is removed and then the aqueous dispersion of the polymer is subjected to a pressure of from 150 to 650 torr for at least 15 minutes to evaporate off from 0.2 to 20 kg of water per 100 kg of dispersion. This process achieves residual monomer contents of less than 0.005% by weight of vinyl chloride. This reduces any harmful physiological effect of monomeric vinyl chloride in the handling of these polymers.
