Title: Improvements relating to the manufacture of cartridge belts
IPC: F42B39/08
Filed: 1942-03-18
Abstract: 556,155. Making links for cartridge belts. ABBEY, A. (Bliss Co., E. W.). March 18, 1942, No. 3570. [Class 92 (ii)] [Also in Group XXII] Links for cartridge belts of the type in which the ends of the links are formed into eyes for receiving, the cartridges which function as the pivots of the chain, are formed from strip metal in a series of press operations, the first stage being the severing of the completed link from the stage of partly formed blanks. The strips are guided between a fixed guide 2 and a resilient guide 3 and as it progresses holes 4, notches 6, 8, holes 5, slits 10, 11, 12, 13, and offsets 19 are formed the ends, 22, 23 and 24 of the tongues are preliminarily curved, depressions 25 are made, and finally the tongues are formed into closed rings, that formed by the tongue 15 being flared to fit the tapered part of the cartridge. The notches may be used for the reception of the finger of an electrical detector to protect the links against damage due to defective feeding. During the bending the previously unsevered parts 17, 18 are cut thus severing the completed link from the stock. In forming the offsets 19 the metal is so stretched that the space between the rings 14, 15, Fig. 7, becomes wider than the ring 16 so securing easy pivotal movement in the assembled belts. The rings are formed round mandrels 26, 27, Fig. 3 carried by a vertically movable slide 28. A resilient blank holder 29 first engages the depressions 25 and side dies 31, 32 bend the tongues to project vertically downwards. The dies then continue their descent together with the slide 28 which actuates the ends of bell cranks 35, 36 turning about fixed pivots and so closes in the side dies 33, 74 to complete the bends. An ejector not shown strips the links from the mandrels.
Patent GB-679619-A (GB)
Title: Improved process for the production of ropes from artificial filaments
IPC: D07B1/02
Filed: 1949-02-10
Abstract: Rope yarns (i.e. yarns of heavy denier used as the unit in the making of ropes) are produced by collecting together a sufficient number of continuous artificial filaments into the form of a tow without twisting the filaments, the filaments being drawn (stretched) before or after the formation of the tow.  The tow is defined as a bundle of continuous filaments which has not been subjected to any twisting operation.  The filaments are preferably formed into the tow as they come from the spinneret, the tow being then drawn and sized before reeling to facilitate its unwinding from its package.  The filaments may be heated during drawing and after drawing may be subjected to a heat-setting treatment to make the rope yarn more heat stable.  The artificial filaments may be nylon or highly polymerized polymethylene terephthalates.  In the example, a 6000 denier rope yarn is made by melt spinning polyethylene terephthalate continuous filaments from 70-hole spinnerets and winding them up on bobbins.  Forty-two of these bobbins are mounted on a creel and the yarns from them collected into a tow by means of guides.  This tow is passed through a pair of nip rolls and a set of 10.8 cm. diameter feed rolls rotating at 150 r.p.m., the last feed roll being maintained at 80 DEG C., and then between two hot plates maintained at 180 DEG  C. to a set of 10.8 cm. diameter draw rolls rotating at 825 r.p.m.  A mineral oil emulsion size containing diethylene glycol as an anti-static agent is then applied to the tow and the latter reeled. Specifications 578,079, 590,451 and 603,838 are referred to.

IPC: B41M1/42
Filed: 1968-01-24
Abstract: 1,215,486. Printing-apparatus. J. R. BURTON. 24 Jan., 1968 [30 Jan., 1967], No. 3756/68. Heading B6C. Printing surfaces.-A printing plate is produced by forming depressions 18, Fig. 1, in a rigid foam plastics layer 14 which is supported on a base such as 12 of tough material which limits the depth of the depression to the thickness of the layer 14. Polymers suitable for the production of a rigid foam include polyurethane, polystyrene, polyvinyl chloride, phenolformaldehyde, polysiloxane, and epoxy resins. The base 12 may be of metal or plastics material or may be formed for example during the moulding of the plate blank by the application of heat and pressure to one surface of the foam material so as to form, after cooling, a hard high density backing layer (26), Fig. 2 (not shown). A stylus 16, a pencil, a ball point pen, or piece of typewritten type (34), Fig. 4 (not shown), may be used to crush the foam to form a high density portion 20 along the walls of each depression. The plate produced may be an intaglio or relief plate. Before the image is formed the upper surface of the blank may be subjected to heat and pressure, Fig. 3 (not shown), or may be bonded to a smooth plastics sheet (12A), Fig. 1A (not shown). The printing plate may be used as a mould, Fig. 8 (not shown), to form a relief printing plate. Rotary intaglio printing apparatus.-A printing plate 10 according to the invention may be secured to a cylinder 40, Fig. 5, powdered material 42 being supplied to the image areas from a hopper 44 and excess powder being removed by a doctor 48. A heated plastics offset roller 50 causes the powder in the image depressions to melt and be transferred to a web 52. In a modification, Fig. 6 (not shown), the offset roller (50A) is not heated but is charged by an electrode (56) which facilitates image transfer to the offset roller. The image is transferred to the web (52) by charging the web with an opposite polarity or by heating the impression roller (54A). The plate may be mounted on a pivotable segment of a cylinder, Fig. 7 (not shown).
