Title: Speed/torque control of electric motors
Inventor: BAYLEY DEREK LEWIS
IPC: H02P6/00
Filed: 1992-04-03
Abstract: An electric motor 1 is operated by selectively energising circumferentially distributed coils 4, 5, 6 of a stator via a commutation circuit 7 to apply torque to a rotor 2 having permanent magnetic pole elements, selected coils being energised in accordance with a commutation sequence whereby the commutation circuit switches between successive phases of the commutation sequence in response to sensed changes in the angular position of the rotor. During each commutation phase a field control current is applied through further coils of the stator which are substantially in radial alignment with respective pole elements relative to the rotation axis of the rotor during at least part of the commutation phase so as to modify the flux associated with the pole elements and thereby modify the torque produced by the selected coils. The speed/torque operating characteristics of the motor can thereby be externally modified. <IMAGE>

Title: System for re-melting an electrode
Inventor: MULLER FELIX
IPC: F27D99/00
Filed: 1992-08-05
Abstract: A pressure reservoir (9) is located on a melting pot (2) which surrounds in a pressure sealing manner the electrode (6) to be re-melted. The bottom end part of the electrode is immersed in a melting bath (7). The bottom (3) of this melting pot (2) has an outlet (5) from which the re-melted metal emerges as a stream. The outlet is surrounded by an electric coil the current through which determines the strength of an electromagnetic field and impedes to a greater or lesser extent the flow through the outlet. This control is augmented by increasing the vacuum in the pressure reservoir (9), enabling the flow of metal to be decreased or stopped. <IMAGE>

Patent GB-2299791-A (GB)
Title: Movable vehicle deck with means to keep deck level during movement
Inventor: PIGGOTT TREVOR
IPC: B60P1/02
Filed: 1995-02-23
Abstract: The deck 1 is raised and lowered by four hydraulic rams 2 acting between the vehicle body 3 and the deck 1. Movement of the deck 1 is synchronized by the interaction of two toothed racks 4a,4b mounted on the body 3 with respective toothed wheels (8a, fig4) mounted on the platform. The toothed wheels (8a) are connected by a transmission means such as a shaft 9a, or an endless chain, which ensures that rotation of one of the toothed wheels causes the other one to also rotate and thus even if the hydraulic rams do not themselves tend to move the platform equally such that it is level, the transmission shaft 9a ensures that the platform is maintained at a level disposition.

The connection mitigates radio frequency intermodulation problems in cellular networks. A screw clamp 7b may form the clamp for the first seal. The connection between the piece 3 and the 4 support may be reinforced by a screw clamp 8c. <IMAGE>

Title: Method and apparatus for actuating a downhole tool
Inventor: HOLCOMBE MICHAEL W
IPC: E21B34/06
Filed: 1995-10-20
Abstract: A downhole tool, such as a packer or sliding sleeve valve, is actuable from a non-electrical signal transmitted from the surface to the tool. The signal is received at the tool by a control system located within the tool. The control system operates in conjunction with a power supply in the tool to accomplish tool actuation. In the preferred embodiment a valve member such as piston 60 is temporarily retained in a sealing position, isolating pressure in one chamber from a different pressure in an adjacent chamber. The piston 60 is temporarily retained by a high-strength fibre 84, such as Kevlar (RTM). The control system actuates the power source to heat a resistance heating wire, which causes failure in the fibre 84. Other mechanisms to trigger pressure-equalization can be used. The fibre can be cut by a cutter actuated electrically. The piston can be retained by solder which is melted electrically. The piston can be designed to be substantially in pressure balance so that the fibre can effectively hold the piston in place until it is rendered inoperative by heating up a resistance wire from the power supply as triggered by the control circuit. Once the fibre fails, the piston is released and the pressure is equalized. The pressure-equalization can be used to shift a setting sleeve to set a packer or to open or close a sliding sleeve valve. Different valves can be actuated in series, using different control signals, or in parallel, using one control signal. In the alternative, the same valve can be actuated to open and then to close, depending on the procedures desired. The resistance wire is threaded into the fibre cable to ensure effective transmission of the heat for proper release of the piston when desired. <IMAGE>

IPC: F02P17/12
Filed: 1995-11-07
Abstract: An electrical lead for the high tension circuit of a spark ignition system for an internal combustion engine, comprises an elongate conductor having an insulating sheath, a light emitting diode (LED) connected in shunt arrangement with the conductor and a resistance in parallel with the LED. The conductor may be metallic but is preferably flexible carbon, a short length of the carbon conductor being used as the parallel resistance. In some embodiments the LED may be connected to the conductor by insulation-piercing contacts (Figures 1, 4, 5, 8 to 10, 13 and 14). In other embodiments (Figures 2, 4, 6 and 7) the conductor is severed and an LED (116) and resistor (118) are connected across the ends of the conductor. Other embodiments (Figures 11 and 12) use several LEDs or banks of LEDs with resistances of different values thus giving an indication of the strength of the current.

Patent GB-954885-A (GB)
IPC: F01L23/00
Abstract: 954,885. Percussive drills. DOWTY MINING EQUIPMENT Ltd. July 25, 1960 [May 11, 1959], No. 16085/59. Heading B4C. [Also in Division F1] In a pneumatic or hydraulic pressure reciproeating engine for supplying power to rock drills or hammers, a piston 3 slidable in a cylinder 2 has a piston-rod 4 extending through a sealed opening 5 in the cylinder for transmitting reciprocating energy, e.g. to the spring-loaded head 7 of a drill, and a sliding valve 14, 15, capable of oscillation with springs 21, 23 associated therewith, connects each end of the cylinder 2 alternately to fluid supply and return ports 24, 25 through fluid passages 28, 29 to cause reciprocation of the piston in accordance with oscillation of the valve, the piston being connected to the springs for transmitting reciprocating energy thereto to maintain the valve in oscillation whereby reciprocation of the piston is also maintained. As shown, the piston is formed with a recess 11 equal in diameter to the piston-rod diameter and sealingly engaging in the upper end of the cylinder 2 a projection 12 provided with a bore 13 forming the valve cylinder. Alternatively, the piston is provided with a hollow rod extending in a sealed manner in the casing 1 and connected to a valve cylinder. The valve rod 16 is formed with a head 19 and a shoulder 22 between which and a flange 18 in the piston bore the springs 21, 23 are compressed. In the position shown, the piston 3 is displaced slightly upwardly by a spring 8 acting on the drill head 7. To commence operation, pressure fluid is supplied through port 24 and passes through port 26 to piston 3 urging it downwardly. The piston will then start to oscillate at a frequency governed by the actual frequency of the valve and springs, reciprocating energy being transferred to the drill head 7 by impact. In a modification, inlet and return ports are provided respectively on the outside and between the lands 14, 15 of the valve and pressure fluid acts on the whole cross-section of the end of the piston opposed to the piston-rod.

Title: Metal matrix composite alloys
Inventor: ELLIS JONATHAN DUDLEY
IPC: C22C1/10
Filed: 1996-08-08
Abstract: The invention provides a method of introducing a carbon-containing reinforcement material such as titanium carbide into an aluminium-containing melt by treating the reinforcement material with a wetting agent such as a K-Al-F slag, then contacting it with the melt so that it becomes incorporated into it, and casting the resulting reinforcement material-containing melt. The invention addresses the problem of aluminium carbide associated with the reinforcement material in the cast product. To at least mitigate that problem, the surfaces of the reinforcement material are treated, prior to incorporation into the melt, with titanium, which is preferably supplied by the wetting agent. A preferred wetting agent is a residual K-Al-F slag containing up to about 0.1% by weight of titanium.
