Abstract: 1,146,398. Cross-linking aromatic polymers with polysulphonazides. GENERAL ELECTRIC CO. 3 March, 1967 [11 April, 1966], No. 10310/67. Headings C3P, C3R and C3T. An aromatic polymer, e.g. polystyrene, a bisphenol-A polycarbonate resin, polyphenylsilsesquioxane, polyarylene oxide or polymethylphenylsiloxane, is cross-linked by heating with an aromatic polysulphonazide having sulphonazide groups attached directly to the aromatic ring(s), e.g. 1,3-benzene-bis-aulphonazide. In Examples (1) a solution of polystyrene in methylene chloride was mixed with the sulphonazide, dried and heated to cross-link the resultant film; (2) a copolymer composed of diphenylsiloxy and dimethylsiloxy units was crosslinked with the sulphonazide; (3) poly-2,6-diphenyl-1,4-phenylene oxide and poly-2,6-dimethyl-1,4-phenylene oxide were cross-linked as (2); (4) a solution of polyphenylsilsesquioxane and the sulphonazide in benzene was cross-linked as in (1); and (5) a bisphenol-A polycarbonate resin was cross-linked as in (2).

Moulding-machines.-A machine for packing sand comprises a flask receiving table 13 with a hollow stem guided in a trunk 10 in the frame, and slotted to pass a hand-operated rock-shaft actuating linkage 28 within the stem. The connexion is loose at 28<1> to permit the machine to be operated by jar-ramming. Final pressure is obtained against a head 47 carried by swing arms fitted with balancing springs (not shown). Hoods 35 on the bearings in the trunk act as a protection from sand and the rock-shaft is retained against end movement by a set-hoop 32 with a hood 33 extending for about half the circumference and embracing a rib 34 on the frame. The castings 42 which receive the swing arms have a similar engagement with the frame. The pivot is a length of pipe clamped in a recess in the frame by setscrews and lock-nuts 58. Nuts 56 forming the clamping-abutment are received in pockets in the frame thus avoiding tapping. Limit screws 62 for the motion of the swing arms are similarly mounted in lugs of the frame.

A conveyer comprises a tube 11 of plastic or stainless steel, and a flat flexible endless nylon belt 10 which has inherently low friction characteristics and is without any absorbent reinforcement material. The belt 10 has an upper reach trained through the tube 11 and is arranged to slide in the bottom of the tube 11 in trough shape with a lower return reach underneath the tube 11. The belt 10 passes over crowned idler and drive rollers 12, 15, which centre the belt 10, and over curved return shoes 13. A head assembly 20 comprises a bracket 23 supported on the tube 11 by split collars 24, 25 and carries troughing rollers 16 and the idler roller 12 with belt tightening screws 35. A tail assembly 21 comprising a bracket 56 is similarly mounted on the tube 11 by split collars (50), (51), Fig. 4 (not shown), and carries troughing rollers 16, the drive 15 and a motor 55. Other split collars 40 with hanger brackets 41 for connection to suitable supports 43 are provided at intervals along the tube 11. The tube 11 protects the material on the belt 10 from drafts and also forms a flue inducing a flow of air and thus reducing the head resistance. An external blower may be used to eliminate the head resistance by producing a flow of air at the same velocity as that of the belt 10. The tube 11 provides exclusive support for the brackets 23, 56, rollers 12, 15, and the motor 55 and is readily portable. Reference has been directed by the Comptroller to Specification 1,043,067.

[Class 39 (iii).] In a liquid-heating vessel which is open to the atmosphere and is adapted to be tilted to cause the heating medium, e.g. an electric current or gas, to be cut off, the vapour generated is utilized to tilt the vessel by displacing a portion of the liquid therein. An electrically-heated vessel 11, movable about an axis 14, comprises an auxiliary reservoir 12 which, when the liquid reaches a certain temperature, is filled with vapour at a pressure sufficient to lower the level of the liquid therein and to tilt the vessel to operate a mercury switch 15. Reheating is effected by returning the vessel to its original position, by adjusting the position of the tilting axis, or by the provision of a movable balance weight, or by the provision of a hole or valve at 18. The vessel may be adapted to tilt about two of its feet, and to operate a gas tap. The reservoir may be fitted to a lid by means of a bayonet joint, or may be formed by a partition fitted within the vessel.

[Class 59.] In a mill for crushing coke &c. a screwthreaded spindle 17 is connected to each journal of the displaceable roller and carries a spring 22 between a dog 19, in which the spindle is adjustable and which normally abuts a rigid support on the frame of the machine, and a flange 23 adjustable longitudinally on rods 24 relatively to the spindle 17, the flange being adjusted by nuts to alter the compression of the spring, the roller being adjusted independently by the rotation of the spindle 17 in the dog. As shown, the roller 1 is mounted in fixed bearings and the roller 7 is adapted to be adjusted horizontally in a recess 5. A main drive shaft 10 is mounted in a vertical plane below the shaft 8 of the roller 7 and drives the latter through gears 12, 13. The roller 1 is driven from the shaft 10 by gears 14, 15, 16 or by a chain. Movement of the roller 7 to an adjusted position in the slot 5 does not interfere seriously with the meshing of the gears 12, 13. The ends of the roller 7 are adjusted simultaneously by screwing the rod 17 through the flanged dog 19, the end of the rod engaging the bearing 6 of the roller 7. The dog 19 is forced against the casing by the spring 22, the pressure of which is adjustable by the flange 23 and the moving roller is maintained in parallel alignment with the stationary roller by levers 20 fixed on a transverse rod 20<1>. Both rods 17 are rotated simultaneously by a worm and wormwheel.
