Abstract: 379,246. Furnace grates. LINIGER, M., Visp, Switzerland. March 30, 1932, No. 9134. Convention date, April 10, 1931. [Class 51 (i).] In a travelling grate of the kind in which a series of individually movable firebars are advanced into the furnace along an upper track and returned along a lower track, the firebars, at the end of their forward travel, fall through a guide into the path of a pusher or like feed device which feeds the bars back to the upper track through a curved return guide. Firebars 1, each having a substantially equal cross-sectional height and width, are advanced along an upper track 7 by a pusher 3, which pushes each individual firebar past a latch 6 which prevents retrogression. The bars travel past a fuel hopper 8, beneath an adjusting member 9 into the furnace 10, and fall down a guide 12 in front of a pusher 13 which feeds them back along the lower track 15. At the end of the lower track they fall down a guide 16 at the bottom of which 'the pusher 3 is situated. Worm conveyers or other clinker removing devices may be arranged in the lower track. In a modification, the downwardly directed guide 12 may be curved and the pusher 13 dispensed with, the movement being effected by the pusher 3 above. In another form, the guide 16 is curved and the pusher 13 alone effects the movement. Clinker may be removed at the curved portions of the guides.

Abstract: 104,993. Winkler, C. July 4, 1916. Cylinder machines; gripper mechanism. -In an oscillat in g - cylinder printing-machine of the kind described in Specification 17820/99, in which the grippers close upon the sheet just after the cylinder has begun its forward movement, the grippers are actuated by mechanism which causes them to close gradually, so that they slide on the front margin of the sheet with a tendency to smooth it out and lower it towards the front stop, the grippers being fully closed when the acceleration of the cylinder, although small, has become regular. The grippers 9 are constructed so that a line joining their points with their axis of rotation forms an acute angle with the feed-table 8, and are closed by a spring (not shown) attached to the arm 19, the closing being controlled by the engagement of a roller 15 on the arm 19 with a cam 16 carried by a lever 10, which is oscillated by a connexion with the driving-shaft of the machine. When the cylinder is at rest, the grippers 9 overhang the front margin of the sheet on the feed-table and are held open by the cam 16, which is then in its raised position. When the cylinder commences its forward rotation, the cam 16 is lowered, and the grippers are closed gradually by the spring.

Abstract: 100 parts of an oily polymer of a C4 to C6 conjugated diene are cross-linked with 1 to 30 parts of an acrylic acid ester of a polyhydric alcohol and optionally 0-70 parts of a further monomeric cross-linking agent.  The oily polymer may be a homopolymer of butadiene, isoprene, hexadiene, dimethyl butadiene, piperylene or methyl pentadiene or a copolymer with styrene, acrylonitrile or methyl vinyl ketone.  The ester may be an ester of acrylic, methacrylic, a -chloro or-bromoacrylic acid with ethylene glycol, diethylene glycol, a propylene glycol, a butanediol, glycerol, 1,1,1-trimethylol propane or pentaerythritol.  The further monomer may be styrene, vinyl toluene, 2,4-dichlorostyrene, butyl methacrylate, diethyl fumarate, diallyl phthalate or vinyl stearate or mixtures thereof.  0,5 to 10 parts of a catalyst such as dicumyl peroxide, di-t.-butyl peroxide, benzoyl peroxide, di-t.-butyl phthalate or t.-butyl perbenzoate is added.  Up to 2 parts of 2,6-di-t.-butyl paracresol and 50 to 200 parts per hundred of resin of a filler such as clay, silicates, carbonates, carbon black or asbestos may be incorporated.  Polymerization is carried out round a fibre such as glass fibre (which is preferably treated with an unsaturated organo halo silane) by baking in a mould for 2 mins. to 2 hours between 240 DEG F. and 375 DEG F.  An optional post cure of 1-10 hours between 250 DEG  and 400 DEG F. may be used. Alternatively the resin mix may be moulded for 1/2 minute to 4 hours between 140 DEG  and 350 DEG F. to form a B stage resin and then finally cured for 1 minute to 2 hours between 300 DEG  and 400 DEG F. A further procedure is to make a graft polymer by heating the mix (without glass fibre) in an inert solvent for 15-20 minutes, laminating with the fibre and curing further.
