Title: Battery charger for charging various kinds of battery
Inventor: JUNG YEON-TAK
IPC: H02J7/02
Filed: 1997-07-07
Abstract: A battery charger selects an appropriate charging level in dependence on the detected nominal or rated voltage and capacity of a battery 400 to be charged. The battery 400 incorporates a resistor R11 to indicate its rated voltage and a resistor R12 to indicate its rated capacity. An output voltage controller 214 has a charging voltage detector incorporating a voltage divider for sensing the charging voltage being applied to the battery. A detector 215, for sensing the rated battery voltage from resistor R11, causes a transistor (Q2, Figs.2,4) in the voltage divider to be turned on or off to alter the dividing ratio according to the sensed rated battery voltage. The controller 214 disconnects the charging current if the applied charging voltage exceeds the rated voltage of the battery being charged.

Title: Torsional vibration damper
Inventor: SUDAU JORG
IPC: F16F15/131
Filed: 1998-01-23
Abstract: A torsional vibration damper acts between two transmission elements 2, 12 rotatable relative to one another about a common axis, a movement applied to one of the transmission elements 2 being transmitted to the other of the transmission elements 12 by means of a coupling device 30 which has a coupling member 16 mounted pivotally on one of the transmission elements. The coupling device 30 furthermore has associated with it at least one guide track 24 in the other transmission element, along which a thrust member 20 connected to the coupling member 16 is guided. As the rotational speed of the elements increases, the thrust member is urged radially outwards due to centrifugal force, and the force required to cause relative movement between the transmission elements increases.

Title: Moulding hygroscopic plastics material
Inventor: WOODS PATRICK
IPC: B29C37/00
Filed: 1998-01-22
Abstract: A method for moulding hygroscopic plastics material in a clean room environment comprises drawing granules of hygroscopic plastics material from a supply container 10 into a hopper loader 13 by means of a vacuum drawn on the hopper loader 13 by a plant room vacuum pump. The granules are then delivered into a drying hopper 15 and air from the drying hopper 15 is drawn by a dessicator vacuum pump in a closed loop to substantially remove moisture from the air in a dessicator 22. Heated air from the dessicator 22 is delivered to the granules in the drying hopper 15 to substantially remove moisture from the granules. On removal of moisture from the granules in the drying hopper 15, the dessicated granules are drawn to a hopper loader 1 of a moulding machine in the clean room environment by means of a main vacuum pump 30. The main vacuum pump 30 draws air in a closed loop from the hopper loader 1 of the moulding machine through a dust separator 31 and a filter 32 and draws the dessicated granules from the drying hopper 15 to the hopper loader 1. Positive pressure in the dessicated granules stream is released prior to delivery to the hopper loader 1 to maintain the integrity of the clean room environment.

Title: Composite materials comprising alkaline earth silicate fibres
Inventor: JUBB GARY ANTHONY
IPC: C04B14/46
Filed: 1998-09-15
Abstract: A composite material comprises inorganic bonded alkaline earth silicate fibres in which any bonding agents or fillers comprise low amounts of Al such that the composite material comprises less than 1% by wt. Al expressed as Al<SB>2</SB>O<SB>3</SB>. alkaline earth silicate fibres are preferred for use in composites as they are soluble in body fluids and less likely to cause the respiratory problems characteristic of highly insoluble asbestos. However they are more reactive than asbestos and their performance at high temperatures is reduced. This is attributed to the presence of Al in associated binders and fillers. Thus by reducing the Al content the performance is enhanced.

Title: Blowerflow injected two-stroke engine
Inventor: WHYMAN STUART PAUL
IPC: F02M35/10
Filed: 1999-04-26
Abstract: Air is blown through the venturi(3) where it increases in velocity into the cylinder to purge it through the inlet port(2) while uncovered by the piston(9). The piston rises, closing the inlet(2) and exhaust(4) ports and compression begins. While the inlet port is closed, air flow is prevented from passing through the inlet manifold into the inlet port. Depression created in the venturi associated with the cylinder being purged is used to draw and relieve air pressure developing in the closed inlet ports of cylinders on the compression and power strokes via inlet transfer ducts(5) to assist purging and charging the cylinder with clean air before compression. An engine management/fuel injection system delivers fuel into the cylinder after the inlet port has closed ensuring that only air is passed to the exhaust system during the purge operation, eliminating the possibility of fuel passing directly to the exhaust.

Title: Shifting frequency subsets to avoid interference in a frequency hopping cordless telephone system
Inventor: SYDON UWE
IPC: H04B1/715
Filed: 1999-06-08
Abstract: A method and system are disclosed for shifting frequency subsets to avoid base station interference in a frequency hopping cordless telephone system. A base station communicates with the handsets using frequencies selected from active frequency subsets. Frequency subsets are shifted to avoid interference by selecting frequencies initially from a defined number of active frequency subsets where each of the active frequency subsets is used before repeating an active frequency subset (eg 10 subsets). The number of active frequency subsets is then changed (eg to 11 subsets) for a defined period of time to change the period with which the active frequency subsets are used. After the defined period of time, the number of active frequency subsets is returned to the defined number of active frequency subsets.
