Title: Furnace blocks having metal casings and methods of and apparatus for making such casings
IPC: B32B18/00
Filed: 1971-06-24
Abstract: 1333452 Making furnace bricks; angular bending; seaming; bending punches GENERAL REFRACTORIES CO 24 June 1971 [30 June 1970] 29725/71 Headings B3A B3E B3J and B3W [Also in Division F4] A metal casing is applied to a refractory brick 22 by bending a metal plate 36 around the brick so that the ends 38, 40 of the plate 36 overlap and joining together the overlapping ends. The metal plate 36 is correctly positioned relative to a movable support 80, Fig. 4, by pins 132, (134), 136 and is moved together with the brick 22 by an hydraulically operated ram 70 through a stationary die 56 and a die 58 which is moved back against spring bias 60 to cause the metal plate 36 to be bent against the sides of the brick 22. At a second station, Fig. 6, a block 104 is moved towards a stationary block 94 by cams 119 when a platform 111 is lowered by an hydraulic cylinder 114 causing pivoted arms 88, 98 to bend the ends 38, 40 of the plate 36 towards the top surface of the brick 22, the plate 36 being held against the sides of the brick 22 by blocks 120, 126. Upon further downward movement of the platform 111, the plate ends 38, 40 are bent into contact with the brick 22 by a plate 106, an offset portion 42 of the plate end 40 being located in a groove in the brick 22. Subsequently, the plate 106 is moved upwardly against the action of springs 110 to expose pointed tools 118 which pierce the overlapping ends and form curls 46, 48, 50, 52 which extend into depressions 34 in the brick 22. The overlapping ends may alternatively be joined together by welding. The plate 36 may be embossed and asbestos may be positioned between it and the brick 22.

Abstract: 1,091,577. Photo-electric torque-measuring apparatus. BLACKSTONE & CO. Ltd. July 14, 1965, No. 29902/65. Heading G1A. The transmitted torque in a rotating shaft is measured by measuring the phase difference between two sets of equiangularly spaced chrome reflectors 15, 16 which are axially separated by a torsionally resilient coupling 13. A transistorized bi-stable circuit 20 is set in one state every time light from a reflector 15 hits a first photo-cell 17 and is set in the other state every time light from a reflector 16 hits a second photo-cell 17. In the absence of torque, reflectors 16 are 180‹ out of phase with reflectors 15 and the bi-stable circuit spends equal times in each state. In the presence of torque, the bi-stable circuit spends more time in one state than the other whereby the average output current received by a meter 19 is indicative of the transmitted torque. The output may be used to operate torque control means (not shown). A common light source (not shown) may be provided or each set of reflectors may have its own source. Pulse squaring circuits 18, 18 may be interposed between the photo-cells and the bi-stable circuit.

A semi-conductor wafer, e.g. of germanium or silicon, is diced by coating the slice with an etch resistant layer, outlining the dice to be cut to expose the wafer material at the lines and immersing the marked wafer in an etching solution until the dice are separated. In the embodiment, a silicon slice is coated with wax which is cut through by a scribing tool to expose the wafer along the boundaries of the dice required. The dice are then separated by immersing the wafer in an etching solution of concentrated nitric, hydrofluoric and acetic acids in the volume ratios 3: 1: 1. The wax on the individual dice is then removed in boiling trichlorethylene, and ultrasonic cleaning in acetone and trichlorethylene.

[Also in Division G4] An imprinter for attachment to an adding machine 10 comprises a base-plate 11 supported by side members 14 in an inclined plane above the machine 10 so as to receive an embossed customer-identification plate 12 attached to a receipt book or card 13, means 15 on the base-plate 11 for guiding receipts issuing from the machine 10, and a carriage 16 carrying a roller 17 adapted to be moved over the plate 12 to imprint the matter on the plate on to the receipt. The roller 17 may be non-inked or ink impregnated. The operator can read from the book 13 a customer's outstanding balance which is fed to the adding machine together with the value of a current transaction to calculate a new balance which is printed on the receipt. The roller carriage 16 slides on a rod 18, and has an arm 23 carrying a roller 21 and clips 22 engaging another rod 19. The rod 19 is rotatable in side plates 24 and the rod 18 is mounted in eccentrics operable by a lever 25 to lift the roller 17 for facilitating removal of imprinted receipts. The receipts including duplicates may be fed from a roll into the adding machine, or a shoot 30 may be provided behind the base-plate 11 along which the receipts may pass to the machine. The roller 10a of the machine 10 is rotated by a handle 31 to advance the receipts. Duplicate and original receipts in strip form may be fed reversely through the machine into the shoot 30 prior to the commencement of printing thereof, and a flexible sheet of plastics material initially positioned with its leading edge in the imprinting region may be employed to facilitate the reverse feeding. A serrated blade 29 may be provided to facilitate detachment of the originals of the printed receipts. Also, a separator plate 32 may be pivoted about its lower edge by levers 32a for the same purpose. A dating devce may be provided on the base-plate 11 in the area traversed by the roller 17.

A resilient mounting device comprises a base plate 12 through an opening of which extends a columnar member 18 having two portions a and b separated by a shoulder means 38, spring means 20 supporting the end of the member 18 opposite the portion a, a second spring means 24 urging an apertured member 26 surrounding the member 18 into the plane of the base plate 12. As shown, both spring means comprise a plurality of radial disposed coiled springs which may be damped by plastic sleeves 32. Alternatively the damping may be provided by coil springs wrapped around each spring, or split or solid metal sleeves, either inside or outside the coil springs. Stop plates 34 and 36 are provided at respective ends of the member 18. In operation, under no load, the springs 20 draw the member 18 upwards so that the shoulder 38 is in abutment with the inner periphery of the member 26. Under load, the springs 20 are extended, and resonant vibrations are avoided by the interaction of the two sets of spring means. Lateral oscillations are checked by the springs 24. A cage in the form of two cylindrical members (not shown), spring-urged apart may bear on the member 26 and the springs 20. This has a damping effect and a similar arrangement of spring-urged cylindrical members is described in Specification 571,026. The cage may alternatively bear on the member 26 and the plate 36.
