Title: Powder injection moulding and extrusion
Inventor: HULL BARRY
IPC: C04B35/634
Filed: 1995-01-27
Abstract: A method of injection moulding or extruding an article is disclosed in which a ceramic and/or metallic powder is dispersed in a carrier to form a flowable composition. The carrier is preferably a monomeric cyanoacrylate which is reversibly polymerisable so as to yield a solid polymer, which in turn is capable of undergoing a thermally activated depolymerisation reaction so as to yield the monomeric species. The composition is injected into a mould or extruded through a die and the carrier polymerised in the mould or die. Once the polymerised article has been removed from the mould or extruded from the die, the composition is heated to cause depolymerisation of the carrier and hence its release from the composition. The resulting article is sintered and finished.

Title: Reducing settling time in receiver agc
Inventor: GRAHAM DAVID J
IPC: H03G3/30
Filed: 1997-10-20
Abstract: A method for acquiring rapid automatic gain control (AGC) response in a narrow hand receiver teaches opening the AGC loop (100), setting the gain control signal (106) amplitude of the AGC amplifier stage (104) to a known value, altering the gain control signal (106) amplitude over time, and monitoring the narrow band receiver for an output signal (112). Upon output signal (112) detection, halting alteration of the gain control signal (106) amplitude, closing the AGC loop (100) and commencing normal operation. A particular facet of this approach suggests detecting the output (112) with a verging gain detector (116,132) after the loop (100) is closed and before normal operations are commenced.

Patent GB-2320210-A (GB)
Title: Modular home dialysis system - a method of priming a dialyzer
Inventor: KENLEY RODNEY S
IPC: C02F1/28
Filed: 1996-02-13
Abstract: A method is described for priming a dialyzer placed in an extracorporeal circuit of a nemodialysis machine in situ. The method comprises the steps of substantially filling the extracorporeal circuit and the blood side of the dialyzer with fluid (such as dialysate, RO water, saline, etc.), and inducing pressure pulses in the fluid. The pressure pulses cause air bubbles from the blood side of the dialyzer to be sheared off the dialyzer membrane. The air bubbles are then conducted from the dialyzer and removed from the extracorporeal circuit. Backfiltering of fluid across the dialyzer from the dialysate circuit into the extracorporeal circuit is performed in synchrony with the pressure pulses to assist in the shearing off of air bubbles from the blood side of the dialyser membrane.
Patent GB-2320625-A (GB)
Title: Controlled semiconductor switches
Inventor: BLABJERG FREDE
IPC: H02H7/122
Filed: 1996-10-03
Abstract: When measuring fault currents in an inverter, in which controlled semiconductor switches are pulse width modulated, PWM-VSI, to convert a DC voltage from an intermediary circuit to a 3-phase AC voltage, DC currents are measured in the positive and the negative rail of the inverter, so that it is possible to detect faults originating from both short-circuits and earthing faults, maintaining a high sensitivity when reconstructing phase currents, which can be made by a so-called vector modulation, called (SFAVM), in which the states of the individual transistor switches are defined in a vector room (SFAVM) having six active states in which current flows in the inverter and two active states in which no current flows in the inverter. On the basis of the DC current measurements the phase currents can be reconstructed, and all faults can be detected. As mentioned, the measurement takes place as a measurement of DC currents, and for this purpose two transducers are used, which are constructed in a way that at the same current they give two different physical values, so that if there is no fault on the inverter, the phase current can still be reconstructed. The invention is especially expedient in connection with motor controls, active inverters, active filters, compensators, etc.

Title: Float for "ball cock"
Inventor: PARKS WILLIAM MICHAEL STUART
IPC: F16K33/00
Filed: 1998-06-18
Abstract: A float 1 for a "ball cock" has a recess in the top for collecting a quantity of water during the filling cycle which is not enough to sink the float but causes it to float lower in the water resulting in more rapid filling of the cistern tank or reservoir. Due to the changing angle of the float as it rises on the end of the float arm 3, the water collected in the top of the float moves towards the direction of the float arm 3. This causes the float to tilt about the two pivot pins 7, and water on the top of the float to be tipped out thus suddenly causing the float to rise and abruptly shut the "ball cock" valve. The point at which the float tilts can be adjusted to give the correct "shut off' level.
