Title: Cell Type Determination of Battery under Charge Conditions
Inventor: STEPHENS CHARLES S
IPC: G01R31/36
Filed: 1994-01-19
Abstract: The cell type (particularly rechargeable Ni-Cd or non-rechargeable alkaline) is determined by reference to characteristics of its electrical behaviour during charging. Characteristics which may be used for discrimination include the magnitude of the initial voltage rise (Figs. 1-3) and/or rate of initial voltage rise (sensed by a differentiator 104, peak detector 106, and comparator 108) during charging by a constant current source 116. Alternatively, the fact that the voltage of Ni-Cd cells begins to fall after a time whereas the voltage of alkaline cells continues to rise may be used, or the fact that Ni-Cd cells continue to exhibit their initial voltage rise rate for longer than alkaline cells. In chargers which do not provide constant current, the change of charging current overtime may be used for type discrimination. The charging current may be turned off in response to sensing non-rechargeable cells, whereas when a particular type of rechargeable cell is detected, the charging current can be increased, decreased, or stepped according to the requirements of that cell type. <IMAGE>

Patent GB-2301300-A (GB)
Title: A process for producing a display system
Inventor: KELLY ALBERT
IPC: B21D28/28
Filed: 1995-05-31
Abstract: A display system comprising shelves is produced by producing perforated tubes (using a mandrel) for use as uprights which can support transversely-extending members. The stroke of a press brake is set (12) so that either one face of a tube or two opposed faces may be punched in one punch die stroke. To facilitate this, the mandrel has through-holes and the lower punching surface of the punch dies extend inwardly and upwardly so that it is recessed centrally. After a first set of apertures is punched by five or a sub-set of five punch dies (13), the tube is moved to allow a pivotally mounted guide member to drop successively into each aperture. When the guide member drops into the final aperture (15), the direction of travel of the tube is reversed so that pivotal movement is prevented and a limit position for the tube is reached at which the next punching operation will take place to provide the correct pitch. A very durable coating is achieved by spraying with a polyester coating powder (20) to a thickness of at least 60 microns, the powder having a specific gravity in the range of 1.4 to 1.7. The parts are then baked for approximately 10 minutes at a temperature of approximately 200{C. The parts are then assembled.

Patent GB-2320342-A (GB)
Title: Voltage supply circuit with stabilised output control
Inventor: COPUS JONATHAN HUGH LAMBERT
IPC: H02M3/335
Filed: 1996-12-14
Abstract: The circuit comprises a transistor Q which switches a voltage across the primary winding of a step-up transformer T. The voltage induced in the secondary winding of the transformer is rectified and multiplied by a Cockroft-Walton voltage multiplier VM. A sensing circuit RSE senses the ripple in the output of the multiplier, its output being applied to an operational amplifier P whose output controls the gating circuit GC of the transistor. Such a negative feedback loop maintains the output current constant over a wide range of load resistance across the output of the circuit. When the breakdown voltage of a zener diode Z is exceeded, an operational amplifier L acts as a limiter to modify the operating parameters of the operational amplifier P to limit the max output voltage of the circuit in a gradual and controlled fashion. The circuit may be used in an electronic microbicide apparatus for killing micro-organisms.

A diffuser 15, axially in line with the turbine shaft and an axial exhaust outlet may be employed in conjunction with the turbocharger, this representing an optimised exhaust configuration. The compressors may act in parallel, series or series-parallel relationship to supply air to the engine.
