Title: Machine, e.g. a Press, With Platen-Locking Mechanism
Inventor: PUTKOWSKI LADISLAO WLADYSLAW
IPC: B29C43/00
Filed: 1967-12-01
Abstract: 1,196,279. Presses. L. (WLADYSLAW) PUTKOWSKI. 1 Dec., 1967 [19 Dec., 1966], No. 54873/67. Heading B5F. [Also in Division G1] A machine for applying tension or compression to a body comprises two platens, at least one of which is movable towards the other, and elongated bars movable to and from a position in which the platens are locked together through co-operating teeth on at least one of the platens and both of the bars. In one example, Fig. 1, pressure is applied to a body 27 mounted between platens 8, 12 by means of an hydraulic cylinder 24 and piston 26, the platens 8, 12 being locked together by tie bars 32, 34 having teeth 52, 54 engaging teeth 56, 58 on the platen 12. The tie bars 32, 34 are pivoted on bushings 40, 42 and moved to and from locking position by toggle linkage 66, 68, 66a, 68a operated by hydraulic motors 60, 61. Long stroke movement of platen 12 is effected by an hydraulic cylinder 18 or by toggles, gears, or racks (not shown). Fig. 6 shows a modification in which tie bars, as 32<SP>1</SP>, are moved bodily linearly inwardly and provided with teeth 52<SP>1</SP>, 108 to engage corresponding teeth on both platens 8<SP>1</SP> and 12<SP>1</SP>. Movement of tie bar 32<SP>1</SP> is effected by pivoted links 102, 106 and a vertically movable rod 94. An hydraulic piston and cylinder (not shown) mounted on platen 8<SP>1</SP> may be used to press an object against platen 12<SP>1</SP>. The platen 12<SP>1</SP> may be moved by an hydraulic cylinder 18<SP>1</SP>, and platen 8<SP>1</SP> may be similarly operated or may be fixed to a side guide 4<SP>1</SP> by bolts 112. In Fig. 7 (not shown) downward movement of the upper platen (12<SP>1</SP>) is accompanied by inward movement of the tie bars (32<SP>1</SP>, 34<SP>1</SP>) through cam plates (122, 124) and pivoted camming bars (130, 132) connected to pull rods (94, 142). The interengaging teeth on the tie bars and platens may be shaped as in Figs. 4 or 8A (not shown). In a further embodiment (Fig. 9) the tie bars, as 150, are guided on pins 184 for inward and downward movement by means of a downwardly moved rod 170. This rod has camming portions 174, 176 co-operating with camming surfaces 166, 168 of the tie bar 150. Teeth 156 and 160 on the tie bar 150 co-operate with teeth 158 and 162 on the movable and stationary platens 152 and 154 respectively. The final pressing action of the press is effected as the surfaces 198 of teeth 156 slide over the surfaces 190 of teeth 158 to move the platen 152 downwardly by a distance indicated by y+z in Fig. 9. Movement of rod 170 may be effected hydraulically through a pivoted link 183, or by a toggle linkage. A tensile force may be applied to an object by reversal of the slope of the teeth (Fig. 8, not shown).

Abstract: 1,160,914. Moving coil meters. WESTON INSTRUMENTS Inc. Dec. 8, 1966 [Dec. 29, 1965], No.54911/66. Heading G1Q. The coil 80 of a moving coil meter pivots about an axis 110 outside the coil and the field magnet 42, which is inside the coil, has a polar axis parallel to the pivot axis. The movement is mounted on a base-plate 50 of magnetic material and the magnet is secured, e.g. by adhesive, to the underside of a U-shaped member 18, also of magnetic material, disposed in a plane generally parallel to the base-plate. The magnet Fig. 2 (not shown), is a flat arcuate plate of Alnico or a ceramic and its polar axis is in the direction of its thickness. The coil embraces both the member 18 and the magnet secured to it and the field set up by the coil when energized interacts with the field in the narrow air gap between the magnet 42 and the base-plate 50. The movement has largely conventional pivot bearings and hair spring control which are depicted in detail in Figs. 2 to 4 (not shown). Springs 96, Fig. 1, fitted on prongs 75 of the pointer assembly, function as balancing weights.

The combustible material may be gaseous (e.g. coke oven gas, methane, natural gas) liquid (heavy fuel oil or bitumen) or solid (coal, lignite or bituminous oil shale). The heating of the reducing gaseous mixture to the desired temperature may be effected by use of a plasma torch. The reducing gaseous mixture, which comprises mainly CO and H 2  may have a residue of CO 2  and H 2 O if the reduction of the throat gas is not complete.

Abstract: 1451085 Semiconductor devices RCA CORPORATION 7 Dec 1973 [11 Dec 1972] 56790/73 Heading H1K In a method of making a plurality of diodes of the kind comprising a semiconductor body 12, Fig. 1, sandwiched between mutually perpendicular beam lead electrodes 14, 16, arrays of electrodes 14, 16 are deposited on opposite surfaces of a semiconductor wafer which is subsequently etched away except where it is protected on both surfaces by electrode cross-overs. As shown, Fig. 3, a batch of Schottky diodes is formed by vapour-depositing a layer 21 of Ti on a III-V compound, e.g. GaAs, body 11 comprising a P<SP>+</SP> layer 22 supporting an N layer 20 and an N<SP>+</SP> layer 18. A layer 19 of Au (or Ag) is then evaporated or electroplated on to Ti layer 21, and both metal layers are photoetched to form electrodes 14. Temporary protective and "handle" layers 24, 26, Fig. 7, of Al and Cu respectively, are deposited over N<SP>+</SP> layer 18, and support layer 22 is electrolytically etched away. Schottky barrier electrodes 16 comprising layers of Ti 15 and Au 17 are formed on the exposed surface of N layer 20 by similar steps to those used to form electrodes 14, and layers 24, 26 are removed by etching. Finally semiconductor layers 18, 20 are etched in Caro's acid to produce discrete diodes. Semiconductor devices other than Schottky diodes may be similarly produced, and II-VI compounds, Si, and Ge may be employed as semiconductor.

In a fluid-pressure indicating device the fluid, the pressure of which is to be measured, enters an inlet 13 and deflects a diaphragm 15 which in turn causes a liquid in a sub-chamber 18 to rise in a calibrated tube 19 to indicate the pressure. The zero position of the liquid in the tube 19 is stated to be adjusted by a screw 22 deflecting a second diaphragm 21. The device can be modified for use over different pressure ranges by providing one or more enlarged portions 24, 29 in the calibrated tube 19 and different zero settings 26, 27 and 30 on the tube 19 or chamber 11. In a further embodiment two calibration tubes are provided and have different bore diameters so that a coarse measurement of the pressure is measured in the large bore tube which is then closed at its upper open end and a fine pressure measurement is effected in the small bore tube, Fig. 8 (not shown).
