Title: Coated metal matrix composite component; brake disc
Inventor: MURPHY MARTIN JOHN MICHAEL
IPC: F16D69/02
Filed: 1991-09-13
Abstract: A metal matrix composite component e.g. a brake disc, is provided with a protective coating to prevent displacement of the reinforcing filler in the matrix when the component is placed under load. Preferably the protective coating is metal, alloy, composite, refractory or ceramic which may be applied by electro-plating, plasma deposition or magnetron spattering. The matrix of the composite component may be a metal, eg Al, Mg, Ti or an alloy of these and the disperse phase may be another metal and may be selected from silicon carbide, boron carbide, alumina, carbon, sand, and wires of steel, copper or silver. A typical metal matrix composite comprises 10-40% by volume of silicon carbide in a continuous phase of an alloy of aluminium/magnesium/silicon, aluminium/copper or aluminium/lithium. The protective coating may be a metal, eg Fe, Al, Zn, Cu, Co, Cr, W, In or an alloy thereof or non-metallic, eg alumina. Reinforcing fibres of silicon carbide or carbon may also be present. In an example a component formed of an aluminium alloy with particulate silicon carbide distributed throughout is plasma sprayed with a commercially available sprayable material.

Title: Solid state current sensing circuit
Inventor: MIYAZAKI HIDEKI
IPC: H03K17/082
Filed: 1991-10-14
Abstract: In a current sensing circuit for sensing a main current (I1 I2) flowing through a power semiconductor element or elements (1, 2), by utilizing a second current (12) which is small in magnitude compared to the main current and varies depending on the main current, the second current is compared with a reference current in an arrangement including the series connection of the conducting paths of two transistors 4, 5 and a voltage indicative of the comparison is derived at the junction of the two conducting paths. This voltage may be applied via control circuitry (not shown) to determine the value of load current flowing in power semiconductor element 1. Protection of the element 1 from over-current or current increase with temperature is referred to. The circuitry includes current mirrors 3, 4; 5, 6 may be formed on the same integrated circuit. <IMAGE>

Title: Electromechanical transducer for acoustic telemetry system
Inventor: SPINNLER RALPH FREDERICK
IPC: E21B47/01
Filed: 1991-10-24
Abstract: An improved electromechanical transducer for use in an acoustic telemetry system comprises a stack of ferroelectric ceramic disks 94 interleaved with a plurality of spaced electrodes 96A, B which are used to electrically pole the ceramic disks. The ceramic stack is housed in a metal tubular drill collar segment. Thick metal spacer plates 102 are selectively sandwiched between electrodes in order to promote thermal cooling of the ceramic stack. In accordance with an important feature of this invention, the thick metal spacer plates 102 are comprised of a material (such as copper alloys, aluminium alloys or the like) which is softer than the relatively hard, brittle ceramic disks 94 thus reducing the stresses upon the disk when the assembly is subjected to bending, torsion and the like, and thereby minimizing the risk of structural failure of the disks when in operation within a downhole acoustic signal generator. <IMAGE>

Title: Frictional coupling of coaxial shafts
Inventor: RADFCLIFFE SIDNEY JOSEPH
IPC: F16D1/05
Filed: 1992-04-23
Abstract: A sleeve-type coupling 10 for joining torque transmitting shafts 11, 12 end-to-end has a tubular housing 13 containing at each end inwardly tapered bores 15, 16 surrounding both shaft ends and a pair of tapered shells, 18, 19 which form a normally sliding fit on the respective shafts being inserted with the shaft ends into the bores.

Patent GB-932475-A (GB)
Abstract: 932,475. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 30, 1959 [Dec. 30, 1958], No. 44265/59. Class 100 (4). [Also in Group XL (b)] A data processing machine in which data e.g. perforations 39a, 39b, &c. on a record card 20 are interpreted and printed, comprises delay devices 27-0, 27-1 &c. so that printing occurs by the timed operation of a series of single type members as the paper or record card moves relative to the type. As shown in Fig. 1 the record cards 20 are fed so that all columns are sensed simultaneously, position by position, and printing is effected on the end of the cards in positions 23a, 23b &c., but if required sensing could be arranged column-by-column and printing arranged on the long side of the card. When a brush 24a &c. detects a perforation, a magnet 25 is energized and one of a series of arms 62, Fig. 3, is displaced so that its associated arm 63 engages a rocker 66 whose pivotal movement closes contacts 69, 70. A delay, of selective amount, is thereby introduced between the operation of magnet 25 and closure of contacts 69, 70 according to the data sensed. A further delay is introduced to allow for the " order " position of the digit, by means of commutators 29a &c. since if a digit " 9 " is sensed in the column 21b the " 9 " type bar magnet 50 will not be required for operation until the card 20 is fed to the second position. The feed rolls 35, the shaft rotating the delay units 27, the commutator arms 30a &c., and hammer restoring cams 52 are all driven synchronously, but the printing is arranged at closer spacing than a space corresponding to the distance between two perforations. This is effected by variation of the lengths of the arms 63 so that the contacts 69- 70 close at shorter time intervals than the intervals of time for the delay units 27 to pass the magnets 25. In the embodiment shown a 16 point Read-in time is connected to a 21 point Print time. In a modification (Fig. 6, not shown) the delay units comprise cycle point conversion relay units (100a &c.) and continuously rotating discs (102a &c.). Zero suppression arrangements are provided and can be rendered operative or inoperative.
