Abstract: 1,198,403. Fuel cells. COMPAGNIE FRANCAISE DE RAFFINAGE. 6 Sept., 1968 [7 Sept., 1967], No. 42521/68. Heading H1B. In a fuel cell with a cubio-phaae, stabilized ZrO 2  as electrolyte, the anode consists of an electron collector and an oxidation catalyst. The catalyst may be dispersed in the current collector or formed as a lazer thereon. In an example a cathode is formed on the inner wall of a tubular element of stabilized zirconia by painting it with a silver paint and heating it to remove the solvent. A silver current-collector is similarly formed on the outside of the tube. An aq. catalyst-forming solution of Cr(N0 3 ) 3  and AgNO 3  is then sprayed on to the outside of the heated tube. After the spraying the tube was heated at 600-700‹ C. to form a catalyst of Cr 2 O 3  and Ag. Silver leads are welded to the electrodes and the cell is operated at 750‹ C. as as H 2 /air, CH 4 /air or C 4 H 10 /air fuel cell. The current collector may also be of Cu or of ZrO 2  containing a stabilizing oxide and UO 2  and the catalyst may be Cr,Ag, Mo, W, V and/or Cu and/or an oxide thereof.

Title: The lubrication of electrical contact members
IPC: H01R39/22
Filed: 1964-10-21
Abstract: 1,045,094. Impregnating permeable materials; bearings; lubricating. WESTING- HOUSE ELECTRIC CORPORATION. Oct. 21, 1964 [Nov. 4, 1963 (2)], No. 42979/64. Heading F2A. An electrical contact-member for movably engaging with another member in electric contact therewith is lubricated by a dry lubricant comprising NbS 2 , NbSe 2 , TaS 2  or TaSe 2 , or mixtures thereof. An example of such a member is constituted by a carbon or graphite brush 10 (Fig. 1, not shown), engaging with a commutator or slip-ring 20 and provided with a lateral layer 12 of said lubricant. Alternatively, the brush includes particles 16 (Fig. 2, not shown), of one said compounds. The brush may be made of copper whilst the commutator or slip-ring is made of a mixture of copper, or graphite, and said lubricant. The member may be a sliding contact (not shown in the drawings) made of metal, e.g. gold, silver, platinum, copper or alloys thereof, having said lubricant incorporated therewith. Otherwise, said member may be a bearing 32 (Fig. 3, not shown), having a liner 34 comprising, e.g. 25% by weight of TaS 2  in a phenolic resin, or sintered metal, binder. Alternatively, the shaft engaging with the bearing may be provided with a liner 42 (Fig. 5, not shown), comprising 20% by weight of NbSe 2 , or TaSe 2 , in a resin binder. The bearing may be lubricated by particles of NbSe 2  or TaSe 2  suspended in liquid, e.g. oil or water, which is supplied through an aperture 38 (Fig. 4, not shown). Said member may be a ball- or roller-bearing, gears or cams. A carbon brush in accordance with the invention may be made by mixing graphite and/or carbon with 15% by weight of TaSe 2  and 25% by weight of a phenolic resin binder, the mixture being compressed at a pressure of 1000 Ib./in.<SP>2</SP> and temperature between 100‹ C. and 200‹ C. for ¢ hour. The compact is subsequently annealed at a temperature of 800‹ C. for 4 hours in a non-oxidizing atmosphere, e.g. a vacuum or argon gas. NbS 2 , TaS 2  or NbSe 2 , or a mixture of TaSe 2  and TaS 2  may be used instead of TaSe 2 , the compact being annealed at an appropriate temperature. Metal halides may be incorporated in the brush after annealing it. Alternatively, the brush may be made from a mixture of 15% by weight of NbS 2  with silver, the mixture being first heated at 300‹ C. at a pressure of 5 mm. Hg. to remove excess sulphur and subsequently compressed at a pressure of 50,000 Ib./in.<SP>2</SP> at a temperature of 100‹ C. The mixture is finally sintered in vacuo or inert atmosphere at a temperature of 750‹ C. for 6 hours. Copper commutator bars or slip-rings, or similar members including metal or alloys, e.g. silver, and particles of said lubricant, may be made by a similar method, for details of which the Specification should be consulted. Molybdenum disulphide may be mixed with the said lubricant.

Title: Acoustic image converter
IPC: G01S15/89
Filed: 1974-10-03
Abstract: 1437295 Acoustic imaging; peizoelectric arrays; cathode-ray tube displays GENERAL ELECTRIC CO 3 Oct 1974 [3 Oct 1973] 43024/74 Headings H4D H4J and H4T An acoustic image converter comprises a planar array of transducers supplying electrical outputs to respective processing channels. Each channel includes an amplifier and detector followed by a multi-stage shift register. Gating pulses are applied both to the amplifiers and registers so as to store in binary form a representation of the acoustic pressure distribution across the array at a series of spaced time intervals. For read-out of the stored data the registers are connected serially and are clocked by further pulses. The invention can be used to examine biological objects (e.g. the heart) or to detect flaws in objects. In the Fig. 4 embodiment an object is irradiated by pulse-transmitting transducer. 12 and the echoes are focussed by an acoustic mirror on to converter array 20. One of the processing channels is shown at 28. Generator 39 provides a train of (e.g. 5) range-gating pulses corresponding to respective depth planes in the object to be imaged. These pulses gate each amplifier 35 and shift data through each (5-stage) register 37. For read-out of the data, switches 36 couple the registers in series and clock pulses are fed to the registers from generator 42 (or 39). The data is then read-out to a memory, a computer print-out or a stereoscopic display. Instead of using a common network 38 for the data storage and read-out control, separate networks for the two functions may be provided (Fig. 5, not shown). Display details.-The data read-out is displayed (Fig. 8) on two CRTs 52a, 52b by processing it in two channels. The "left" channel produces concurrent displays showing the different image planes Pl<SP>1</SP> ... P5<SP>1</SP> successively shifted to the right and reduced in size. The "right" channel shifts the image planes to the left and reduces their size. The image planes appear at different depths when the CRTs are viewed stereoscopically. The size reduction step may be omitted to give a modified display (Fig. 9, not shown). If colour CRTs are used, the beams for the different colours are shifted laterally and display respective image planes. Converter array details (Figs. 2 and 3, not shown).-The array conveniently comprises 100 sub-arrays, each having a 10 Î 10 matrix of transducers formed by a piezoelectric plate with 100 individual electrodes on one face and a common electrode on the other. Semi-conductor material overlies the individual electrodes and the shift registers and amplifiers are formed as integrated circuits within it. The series connection of the registers minimizes the number of read-out conductors required.

These conduit systems also connect the chambers 54, 56 of another differential control piston 52 to the related chambers 50, 49 of the differential piston spring on the opposite side of the vehicle, the piston 52 acting similarly on another balance lever whose opposite end acts on another selflapping piston valve, similar to the valve 57, for controlling the supply of hydraulic fluid to the brake of the opposite wheel. A spring 65 compensates for the unsprung weight of the wheel assembly. The suspension system includes a damping device in the form of a flow restrictor 43 for each wheel, and a self-levelling device 44 is provided for controlling the flow of hydraulic fluid to and from each container 42, being controlled by a suspension arm 36. A second suspension arm 37 co-operates with the arm 36 in carrying the axle support 35, the differential piston spring being connected between the arm 37 and the chassis of the vehicle. In a modified brake control arrangement, Fig. 2, four piston valves 76 for separately controlling the brakes on four wheels of a vehicle are arranged side by side and are acted on through separate balance arms 81 by differential control pistons 71, a fulcrum 82 controlled by pedal 87 acting on all the balance arms simultaneously.
