Abstract: 686,660. Weighing-apparatus. GENERAL MOTORS CORPORATION. July 11, 1951 [July 18, 1950]. No. 16397/51. Class 143. Means for investigating weight and weight distribution of an article comprises a lever 12 having members 15, 16 mounted by knife edges 14 on a rigid support 10 and a second lever 21 supported by knife edges 20 on the first lever. The lever 21 has a central support for a bracket 24 to which the article is secured by pins 26, 28. The lever 21 comprises also a rod 30 having a link 31, 32 connected by a knife edge 37, 38 to either end and each connected to an indicating pointer 71, 81. The links are similarly connected by a knife edge 74 to a rod 70 supported on the frame 10 by a knife edge 72 on a bracket 73. The pointer 71 is connected to the rod 70. The rod 70 has an arm 75 carrying pendulum resistant weights 76, 77. The main counterbalance of the system is effected by weights 53, 54 and 55 on the first lever eccentrically mounted to vary the sensitivity by varying the centre of gravity. The rod 30 has an adjustable weight 41 and fine adjustment is effected by a weight 46 on a rod 45 of the lever 21. The lever 21 has a dashpot 50, 51 on either side and limiting stops 90, 91. The weights are adjustedso that the standard article gives a zero reading on both scales. When the article is placed on the bracket 24, the first lever 12 and with it the second lever 21 descend, and the indicators record deviation from the standard weight, unequal distribution of weight causes the lever 21 to rotate and the indicators to record different readings.

Title: Improvements in gas-aerometers
IPC: G01N9/10
Filed: 1922-06-19
Abstract: 199,938. Hassenbach, H. June 19, 1922. Specific-gravity estimating-apparatus.-Apparatus for determining the specific gravity of gases comprises a float containing, or surrounded by, the gas and secured to a float which is supported in liquid. In the form shown the float 13 containing air is disposed in a chamber 14 through which the test gas is passed, and is connected by rods 18, 19 and the cross-head 20 with a float 15 supported by liquid in a vessel 16. A rod 25 secured to the float 13 carries an arm 26 to which is attached a recording-pen &c. 27. The vessel 16 has a reduced neck 17 in which the rod 18 is guided by porcelain &c. balls or rollers 24. The diameter of the neck is such that the movement of the liquid surface therein due to changes of temperature compensates that of the float 15 in the liquid due to the same cause. Errors due to variations in atmospheric temperature or pressure may be compensated by making the float 13 resilient. The normal range of indications on the sheet 28 may be conspicuously marked. The movements of the float may be caused to operate a shutter disposed between a source of light and a selenium cell arranged in an electric circuit so that the specific-gravity of the gas is indicated by the current flowing. Variations in the current may be caused to operate a relay, controlling apparatus for regulating the, supply of gas &c. The apparatus may be used. for estimating fire-damp in mine gases &c. In a modification, the float 13 is made rigid, errors due to variations in atmospheric temperatures &c. being compensated by allowing the interior of the float to communicate freely with the atmosphere. Instead of passing the gas through the chamber 14, the gas may be admitted to the float, the chamber then containing air.

Filed: 1971-05-25
Abstract: 1307667 Semi-conductors RCA CORPORATION 25 May 1971 [29 June 1970] 16877/71 Heading H1K In a MIS type insulated gate FET, comprising P+type source and drain regions 12, 14 separated by N-type channel 16 and overlain by a passivating layer 18, a portion of which is removed to expose the surfaces of the source drain and channel; a gate insulator is formed on the exposed surface and etched to provide openings 12, 14. A thin layer, 30 of Pt, Rh, Ru, Os, Ir or specifically Pd is deposited on the exposed semi-conductor in the openings by immersion displacement involving electrochemical exchange with a solution of a salt, e.g. halide, of the metal; containing HF. After heating to sinter the layer 30 into the source and drain regions, other metals of the Pt group may be deposited therein by, e.g. immersion displacement or electroless deposition, and the latter may be carried out before sintering by adding the electroless solution to the immersion displacement solution in which the device is immersed. A further metal, e.g. titanium, layer 40 deposited on the surface and covered by a Pt group, e.g. Pd, layer 42, is selectively etched, e.g. with KI+I solution to define the required electrode pattern; leaving the titanium unaffected. After selective masking to expose the resultant Pd leads, a layer of gold 44 is electroplated thereon, and after remasking to expose portions of layers 42, 44 a thick layer of gold is electroplated thereon to form beam leads. Thereafter the unplated portions of layer 40 are removed to complete the definition of the leads, by etching with H 2 SO 4 +H 2 O 2 +H 2 O, which leaves Pd and Au unaffected.

Abstract: 853,005. Arc-melting furnaces. TITANIUM METALS CORPORATION OF AMERICA. May 27, 1958, No. 16893/58. Class 39(3). An arc-melting furnace arrangement comprises a plurality of furnaces, means in each furnace for releasably suspending therein a holder for a consumable electrode, drive mechanism detachably mountable on each furnace for detachable engagement with the electrode holder therein for lowering or raising the latter, means for positioning said drive mechanism in operative engagement with each furnace for detachable mounting thereon, and means for sealing each furnace during periods of detachment of said drive mechanism therefrom. As shown, arc melting apparatus comprises a plurality of furnaces 12, an electrode drive mechanism 14 and an electrode drive positioning mechanism 16. In operation, a consumable electrode 196 is firmly attached, e.g. by welding, to a contact plate 198 fixed to the base of a ring 200 by volts 202, and this assembly is suspended and centred in the furnace by an upper set of inwardly movable projecting pins 52, Fig. 5 (not shown), operable by handwheels 58, so that it hangs over and partially inside a water cooled crucible 20. The drive mechanism 14 is swung into position by rotating the positioning mechanism 16 and is lowered on to a furnace 12 by the action of a hydraulic cylinder 180 so that flanges 118 and 114 meet with an interposed gasket 116, bolts 120 being tightened to close the furnace. A ram tube 142, the lower end of which is formed with ears 152, is then lowered by the action of a hydraulic cylinder 170 and rotated by means of a motor operating through gears 146 and 144 so that the ears 152 engage with cavities 208, Fig. 6 (not shown), in the ring 200, so that the tube 142 and the electrode assembly are connected together. A push rod 154 is then activated downwardly by a hydraulic cylinder 162 to lock the ring assembly and the suspended electrode securely to the ram actuating mechanism. The upper pins are withdrawn, the interior of the furnace evacuated or charged with inert gas and power to initiate the arc and melting applied, connections being made to the crucible 20 through a connector 50 and to the electrode through the drive mechanism and a connector 212, vertical movement of the electrode during melting then being controlled by the hydraulic cylinder 170. When the electrode 196 has been substantially consumed, the cylinder 170 is actuated to align the ring 200 and its attached electrode stub with a lower set of pins 52, Fig. 5 (not shown), which are run into position to suspend the stub in the furnace chamber. The ram tube 142 is then operated to disconnect from the now suspended stub and raised clear. A flap gate 74 is operated by the rotation of a hand wheel 108 to close the furnace, the stub and the ingot which has been melted remaining in the sealed furnace to cool. The bolts 120 are then removed and the drive mechanism 14 can be re-positioned on another furnace for a repeat cycle.
