Abstract: 895,862. Casting composite articles. SUNBEAM CORPORATION. Feb. 2, 1959 [March 25, 1958], No. 3650/59. Classes 83 (1) and 83 (2). [Also in Group XI] An electric cooking vessel comprises a thin liner and an outer heat-distributing layer of aluminium anchored thereto by means separate and independent of the liner and secured thereto. In one embodiment, Figs. 3 and 4, a woven steel or stainless-steel wire mesh 33 and a wire 42 are brazed or welded to the stainsteel liner 31, the heating element 51 positioned thereon by wire clips 52, and aluminium 32 cast on. The liner has an oversize flange 48 which is cut to size after casting, the flange portion being held between the two die parts as a seal to prevent aluminium travelling to the other side of the liner. The aluminium may be built up by flame spraying instead of casting. In a further embodiment, Figs. 8 and 9 (not shown), the heating element itself, its fixing brackets, and brackets for the leg are relied upon to anchor the cast aluminium, the surface of the liner being roughened by sand blasting or etching. In another embodiment, Fig. 6, the heating element is of sinuous form and held in position for casting by wires 81a, 81b, 81c, welded to the liner 31 and which serve, with the heater and the leg brackets 38, to anchor the aluminium. In another embodiment, Fig. 10, the aluminium is cast on to a low carbon steel plate 103 with projections 105 punched therefrom and copper-brazed to the liner 31. In another example the aluminium is keyed to the liner by fragments of cast iron or steel which are copper-brazed to the stainless steel liner. In another embodiment a grill-like anchoring sheet 143, Fig. 16, having punched-out loops 146 is welded or brazed to the liner. In all embodiments the liner may be sand-blasted and a layer of aluminium sprayed on before the casting step. The anchor layers, e.g. 143, Fig. 18, may be fixed to the stainless steel liner after the latter has been cupped to shape, but preferably, to prevent distortion, the layer is brazed to a plane sheet which is then cupped. Alternatively a stainless steel sheet is partially cupped, the anchor layer brazed to it and then the cupping is completed as shown in Fig. 18.

In a copying process in which an original is exposed to radiation whilst in surface contact with a coated copy material, the material is ordinary paper and is coated immediately before the copying step. As shown, an original is inserted in a feed channel 10 in the direction of the arrow 18 and a copy sheet in the direction 19. A guide plate 14 has an opening 22 through which a roller 23 projects. The roller dips in a container 27 for liquid 28 which is transferred to a sheet of copy paper. The liquid may be zinc stearate or any substance that changes in colour at a certain temperature numerous examples of which are given. A heat source 30 is provided within a reflector 31 beneath openings 29 for drying the coated copy sheet. The original and copy sheet are guided in contact round a cylinder 2 driven in the direction of arrow 9. The cylinder 2 which is of radiation transmitting material, such as glass, has a heat source 30, e.g. an IR-radiator within a reflector 21. An image on the original is thus reproduced on the copy sheet, since the radiation from the heat source is absorbed to a greater degree in the black or image areas and this is transformed into heat which affects the copy sheets in the pattern of the image.

Title: Cathode-ray monograph for recording pressure variations in the cylinders of engines
IPC: G01L23/18
Filed: 1947-02-11
Abstract: 640,154. Electric systems for correspondence control. VICHNIEVSKY, R. Feb. 11, 1947, No. 3921. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 13, 1947.] [Class 40 (i)] The invention is concerned with depicting on a cathoderay tube 1, Fig. 1, the pressure variations in the cylinder of an engine ; the cylinder pressure acts on one side of a diaphragm n, against an adjustable counter pressure from 8 acting on the other side ; movements of the diaphragm n are translated into potential variations, e.g. by producing movements of a piston h controlling contact g to vary the potential applied to the deflecting plates q of the cathode-ray tube ; according to the invention, the cathode-ray beam is rendered ineffective by the opening of contact between diaphragm n and a rod m, so that the portion of the cycle depicted can be varied by adjustment of the pressure from 8. As shown, the opening of contact m, n removes alternating potential supplied from oscillator 2 from the Wehnelt cylinder, leaving it biassed to cut-off the ray. In a modification, the opening of contacts m, n de-energizes a magnetic deflecting coil which normally deflects the spot off the screen. A time base voltage is supplied from a potentiometer 4 whose contact a is rotated by the engine under test. The trace on the cathode-ray tube is photographed alternately with the trace produced by a calibrating voltage. The diaphragm n, Fig. 2, receives cylinder pressure from orifice 33, and adjustable counter pressure through passages 18, 20, 28 ; the rod m has a piston head 25 co-operating with a spring-urged plunger 19, 22, 23, and the piston head is limited in its movement by stop 24, so that when the pressure from 18, 20, 28 exceeds that from 33, contact between n and m is broken.
