Abstract: 897,107. Addressing machines. FABBRICA ITALIANA MACCHINE AZIENDALT. June 17, 1958 [July 24, 1957], No. 19365/58. Class 100(2) A feed mechanism for feeding a series of printing devices, e.g. address plates, in succession along a guideway in a printing machine comprises two reciprocable feeding devices 1, 2 which alternately feed forward the printing devices lying in the guideway, one feeding device returning to its starting position while the. other feeding device moves forwards. The devices 1, 2 together with the guideway disposed between them are located in a recess in the work table of the machine and each has its own slide 3, 4 which reciprocates on a fixed block 5, 6. The device 1 carries feed teeth 71-3 and the device 2 carries feed teeth 8<SP>1-5</SP>. The slides 3, 4 are reciprocated by means of bell-crank levers 17, 17<SP>1</SP> which are oscillated by cams 20, 20<SP>1</SP> which can be clutched to a driven shaft 23 by means of clutches 22, 22<SP>1</SP>. Address plates are extracted from a magazine by the slides 3, 4 and are then fed towards a pressure member 24, where printing is effected, by the teeth on the devices 1, 2. The feeding devices can be rendered inoperative at all stations of the guideway after a given station, e.g. the printing station, by means of a vertically movable platform 25, Fig. 3, underlying the devices 1,2. The platform is spring-biased downwards but may be moved upwards by the rotation of cams 26, 26<SP>1</SP> under the control of a solenoid 28. Such movement causes the teeth, 7<SP>1</SP> and 7<SP>2</SP> as shown, to rotate about their pivots 3 so that they no longer project above the upper surface of their respective feed devices. One of the feed devices may be rendered inoperative by disengaging one of the clutches 22, 22<SP>1</SP>, Specification 897,108 is referred to.

Abstract: 821,897. Moulding plastic facings to concrete building blocks. UNITED STATES RUBBER CO. June 20, 1957 [June 21, 1956], No. 19432/57. Class 87(2). [Also in Group X] In a continuous method for providing building blocks with glass fibre-reinforced resin facings, predetermined quantities of the resin and glass fibre are placed in a series of metal moulds moving along a closed path and the preheated blocks deposited into the moulds with the surfaces to be faced in contact with the resin, while simultaneously applying pressure to the block and heating the resin. At the rear end of the conveyer 20 which comprises a series of shallow rectangular moulds 26, a thin film or shell-coat of resin of the same general chemical type as that of the main facing is placed on the bottom of each mould. The moulds, when in the lower reach of the conveyer, pass through an open ended oven 93 to gel the resin film and they are then cooled by a fan 95 to prevent setting of the resin. The liquid resin for the main facing, e.g. polyester resin, epoxy resin, or polyvinyl chloride plastisol, and compounding ingredients are agitated in container 57, sucked into dispenser 53, and then ejected into the moulds 26. Pre-cut sheets 3 of glass fibre mat and preheated blocks 1 are also loaded into the moulds 26. The moulds then pass over two heating platens 70, 71, the first of which is disposed under press platen 80a. The second platen 71 is about three times the length of the platen 70, sufficient to bring about final setting of the resin. When a block comes into the correct position beneath the press platen 80a, control means, automatically stop the conveyer and cause the press platen to be brought down onto the block with sufficient pressure to mould the facing to the block. Specification 497.175 [Group IV] is referred to.
