Patent GB-967136-A (GB)
Title: Cermet materials
IPC: C22C29/06
Filed: 1962-08-22
Abstract: <PICT:0967136/C6-C7/1> A sintered cermet comprising carbide particles such as titanium carbide, tungsten carbide, boron carbide or silicon carbide bonded by 0.01-1 part by weight of Al, Mg or Ti or mixtures of these, is formed by explosively compacting the powdered carbide and the metal in powdered or massive form in a tubular container and then sintering the compact above the melting point of the metal and below the temperature at which solid state sintering of the carbide occurs.  As shown in Fig. 1, a powder mixture of the carbide and the metal, preferably finer than 200 mesh, is packed in a metal tube 1 which is sealed with metal plugs 3. A layer of detonating explosive 4 is wrapped around the tube 1 and the assembly is immersed in water where the explosive is detonated and the powder mixture is compacted. To form compacted tubes a metal tube is positioned concentrically within an outer metal tube and the powder is placed in the annulus between the two tubes, Fig. 2 (not shown).  The explosive is again wrapped around the outside tube and the explosion is effected under water.  In a further modification, Fig. 3 (not shown), only the carbide is packed into the container in powder form and the metal component is present as a sheath on the outer wall of the central tube and a liner for the inner wall of the outer tube so that the carbide powder is sandwiched between the metal component which penetrates into the carbide during compaction. The compact may be sintered in the assembly or removed prior to sintering.  Examples are given of the formation of cermets of WC-Al sintered at 800  DEG C. in vacuum, SiC-Al sintered at 800  DEG C. in CO2, B4-CAl sintered at 800 DEG C. in CO2, TiC-Mg sintered at 700  DEG C. in air, TiC-Ti sintered at 1100  DEG C. with an acetylene torch. Specification 878,196 and U.S.A. Specification 3,093,521 are referred to.

In rotary positive-displacement pumping apparatus of the Roots'-blower type a probe 36 in each of several units 34 upon a casing 18 for a pair of pumping rotors (10, 12), (Figs. 1 and 2 (not shown), completes a low-voltage electric circuit including the casing and the rotors whenever axial or radial clearance between the rotor and the part of the casing adjacent the probe reach a predetermined minimum owing to thermal expansion. Completion of the circuit aforesaid by contact between any of the probes and the adjacent rotor produces a warning signal. As an alternative the probes may be arranged in pairs, the circuit being completed when the adjacent rotor touches both of the probes in any pair. Each probe is mounted in an electrically-insulating bush 38 supported by a screw-threaded outer-bush 40, and may be furnished with adjusting means of micrometer type to facilitate measurement of the clearance in its vacinity.

Title: Voltage stabilization circuit
IPC: G05F1/56
Filed: 1974-07-25
Abstract: 1434170 Automatic voltage control ITT INDUSTRIES Inc 25 July 1974 [2 Aug 1973] 32869/74 Heading G3R A voltage stabilizing circuit includes a series transistor which is controlled by an amplifier supplied with current proportional to the circuit output current from a first additional transistor, and with current proportional to the difference between circuit input and output voltages from a second transistor. The circuit may be constructed in monolithic integrated form and draws a very low no-load current. As shown in Fig. 4, series transistor T1 is controlled by an amplifier T10-12 in response to output voltage sensed by dividing resistors R1-2. The amplifier receives current from transistors T8-9 connected in current mirror configuration with a diode-connected transistor T7, the current in which is determined by additional transistors T2, T3. Transistor T2 is responsive to the amplifier output signal, so as to produce a current proportional to the circuit output current, and transistor T3 is biased by the difference between the circuit input and output voltages to produce a corresponding current. In another embodiment, Fig. 6 (not shown), the collector of transistor T3 is connected to the base of the series transistor T1 and the amplifier includes a differential amplifier stage. The stabilizing circuit may be mounted with a dry cell battery in a common housing to form a regulated voltage source of about 1 volt for an article such as an electronic watch.

[Class 20 (iv).] A sound-insulating floor comprises concrete cast between or above a plurality of steel girders a which are covered over their entire surfaces with an adhering and practically airtight bituminous coating c adapted to remain substantially resilient, and one or more layers of expanded metal, wire net, or the like, which are suspended between the girders and are coated with plastic bituminous material incorporating asbestos or other fibres. The coating c consists of one or more layers of bituminous or bituminized sheets cemented together and to the surface of the girder by means of a bituminous material containing fibrous material or the like. For example, a coating c comprising a jute fabric, pasteboard or the like may be applied to the whole surface of a girder or to the top flange only, and in the latter case the bottom flange and the web may then be coated with bituminous material containing asbestos fibres, and asbestos wool may be pressed on to the surface of the coating. As shown in Fig. 1, one or more layers of expanded metal or the like are supported on the joists a and coated first with cold liquid asphalt and then with viscous bitumen, and asbestos or glass wool is pressed on to the surface of the bitumen. A layer h<1> of molten asphalt is then deposited, followed by the concrete comprising the main part b<1> of the floor, and after this has hardened, a coating of liquid asphalt is applied, followed by a layer of reed lathing, straw-matting, corrugated pasteboard &c., a coating h<2> of asphalt, and a wearing layer b<2> of slag concrete or the like. A coating of cold liquid bitumen is subsequently applied. Alternatively, the girders may support a wooden floor, and the upper concrete layer b<2> is then omitted as shown in Fig. 2, and the layer of expanded metal &c. is suspended by clips k from the lower flanges. The coating of cold liquid asphalt need not be applied to the layer f in this case. In the modification shown in Fig. 3, the floor consists of two spaced parts of similar form, each comprising a metal layer f, f<1> coated with asphalt, having asbestos wool g, g<1> embedded therein, an asphalt layer h<1> h<2>, and a concrete layer b<1>, b<2>.
