Title: Improvements in or relating to a method and apparatus for ornamenting dinnerware
IPC: B28B11/00
Filed: 1952-05-27
Abstract: 721,174. Transferring designs. DENISON ENGINEERING CO. May 27, 1952 [Dec. 28, 1951], No. 13396/52. Class 100 (2). Designs are transferred to pottery (particularly plates) by applying a resilient pressing force to the centre of both sides of the ware, with the transfer laid thereon, and progressively increasing the area subjected to the pressing force simultaneously on both sides. A dinnerplate 57 coated with adhesive and with a transfer laid thereon may be placed between two rubber or other resilient hemispherical elements 47, 54 which are distorted as pressure is applied by the hydraulic press in which they are mounted, whereby the pressure area is uniformly increased on both sides of the ware, and breakage is prevented. As shown, two rods 25 extend upwardly from the press platen 24 to a yoke 26 carrying a power cylinder 27, the ram 28 of which is connected to a cross head 30 slidable on the rods 25; pressure fluid is supplied to the cylinder 27 from a reservoir by a motor-driven pump via a relief valve and a control valve, the latter being operated by a rod 33 connected to a manual actuating mechanism having a handle at each side of the platen, both of which must be moved (and therefore both operator's hands used) to operate the valve; collars 38 on the control rod 33 are engaged by the cross head 30 to limit the stroke. The resilient elements 47, 54 are attached by studs 48, 55 and nuts 50, 56 to plates 44, 51 secured to the platen and cross head respectively; these plates have conical concave and convex surfaces 60, 61 corresponding to the rim 58 of the ware, whereby uniformity of pressure is maintained right out to the edge of the plate (Fig. 5); flanges 46, 53 support the edges of the compressed elements 47, 54; the plate 44 has holes in its centre part for escape of air beneath the element 47. In a modification the centre part of the plate 44 is vulcanized to the element 47, and an annular rim comprising the conical part 60 and flange 46 is then screwed up around the centre part to give the element 47 a permanent peripheral stress.

Title: An improved fluid filter and method of making same
IPC: B01D29/11
Filed: 1959-04-20
Abstract: 844,440. Filters. CUNO ENGINEERING CORPORATION. April 20, 1959 [April 29, 1958], No. 13459/59. Class 46. A filter cartridge consists of a body formed of a plurality of crisscross wrappings of strand material and independently-applied fibrous or fabric material secured between adjacent wrappings of the strand material and bridging the space between adjacent strands in a wrapping. In Fig. 4, yarn 14 from a spool 15 is wound upon a rotating perforate cylinder 10 through a traversing guide member 21, Fig. 5, controlled by a cam 22. Simultaneously a flat tape-like member 35 is wound through a traversing guide 37 controlled by a cam 38, the whole forming a cartridge A, Fig. 5. The tape 35 may be of the same character as, or a different character from, the material of the yarn 14, and may be parallel filaments as shown in Fig. 5, or of woven or non- woven fabric, Fig. 7 (not shown), or a chaotically disposed web of fibres. In Fig. 8, yarn 14 is wound as before, but the effective filtering medium in this case is derived from a loose sliver 24 of relatively long fibres which is unwound from a supply in a container 25 and fed by a slowly-rotating roll 27 to a rapidlyrotating carding roll 28 whence it is thrown, blown or applied by vacuum to the cartridge A. Adhesive may be previously applied to the yarn 14. Simultaneously, a plurality of parallel wires of aluminium, magnesium or the like (to neutralise alkalis or acids respectively in, e.g. oils to be filtered) is applied from a spool 43. In Fig. 1 (not shown) the wires are omitted, and the yarn 14 passes through the apparatus 17 to 20 (see Fig. 11) besides a guide 16, 17 and 18, Fig. 11, are wet-out rolls dipping into a pan 19, and 20 is a tension device. The yarn 14 passes through an opening 47 in a traverse guide 46 whilst fine filaments 49 of filtering material are fed through openings 48 on either side. The filaments 49 may be replaced by a foraminous web of fibres in tape form fed through slots instead of the openings 48. In all cases glass, aluminium or copper strands may be used instead of yarn 14. Glass (e.g. in fibre form) may be used for the filter material. One of the substances wool and cotton may be used for the strand and the other for the filter material.
