Title: Recharging dry cell batteries
Inventor: ZHIWEI YU
IPC: H02J7/00
Filed: 1986-06-13
Abstract: A dry cell battery is repeatedly recharged soon (one to three days) after each discharge by a substantially constant current up to 1.1-1.33 times its nominal voltage. The charging current may be stabilized by means of a filament lamp in series and/or parallel with resistors, (Figs. 4, 5), or by a regulator having a transistor BG1 in series with the battery. Overcharging is prevented by a protection device in shunt with the battery; this device may be a zener diode or a string of silicon diodes D1 to D5. Additionally, charging current may be disconnected in response to battery voltage by means of a relay having a coil in parallel with the battery and contacts in series with the battery, or by a zener diode BG3 causing transistor BG1 to turn off. The battery charger may be coupled to an appliance powered by the battery using connectors held together by magnets (Figs. 6, 7). <IMAGE>

Title: Methods and apparatus for monitoring the flocculation state of particles in a suspension
Inventor: WEBB TERENCE WILFRED
IPC: G01N15/00
Filed: 1988-01-22
Abstract: Methods and apparatus for monitoring the flocculation state of particles in a suspension in which a field is applied to a region of the suspension and an electrical property of the suspension is monitored in both the presence and absence of the field. The relative change in the value of the property in the presence of the field with respect to its value in the absence of the field is used to monitor the level of flocculation. The field may be an electric, shear, magnetic, acoustic or gravitational field. Although various electrical properties may be monitored several examples of apparatus are disclosed which monitor the conductance of a region. In one embodiment the field is a shear field resulting from the flow of the suspension induced by a pump (65) through a tube (62) between carbon electrodes (60, 61). A conductivity measuring arrangement (67) measures the conductance of the path through the suspension between the electrodes (60, 61) in both the flow and no flow states and a processor (68) controls the pump (65) and records the conductance measured.

Title: Operating incandescent light bulbs to prevent surge currents
Inventor: RIEHEMANN THOMAS
IPC: H05B39/04
Filed: 1988-06-14
Abstract: A small current is supplied to an incandescent light bulb before it is fully switched on. This avoids the very high currents which arise with completely cold filaments and thus extends the life of the bulb. The small current may be a permanent steady current, Figure 1, or a current which rises from zero or other small value at switch-on to full value shortly thereafter Figures 2, 3. These methods of control may be implemented by applying current pulses to the bulb with the pulse width and/or amplitude being varied, (Figures 4 to 6). The methods may be applied to lamps in a vehicle lighting system which may incorporate a multiplexed control system with microcontroller (20), (Figure 8), adjacent the headlight units. <IMAGE>

Title: Procedure and equipment for sterilizing or disinfecting objects
Inventor: WUTZLER PETER
IPC: A61L2/20
Filed: 1989-01-19
Abstract: A procedure and a means is described for sterilizing objects, in particular therosensitive objects, in a closed chamber, e.g. in an autoclave. The use takes place particularly in health institutions, such as hospitals, outpatients departments, etc, as well as in pharmaceutical industry. The sterilization is carried out with an organic per acid, advantageously peracetic acid, in vapour form as derived from an aqueous solution of a concentration from 7% to 50%. In the closed chamber, sterilization is carried out at low pressure or at atmospheric pressure. Employing vacuum increases the concentration of the active agent in the chamber, whereby the requisite sterilization time is shortened. Sterilization is carried out at e.g. 40 to 50 DEG C, which also increases the concentration of the active agent, and whereby a short action time is achieved, involving minimal thermal strain of the objects which are being sterilized. Peracetic acid is environment-conserving because it disintegrates rapidly into oxygen and harmless acetic acid.
Patent GB-2217011-A (GB)
Title: Surface temperature mapping using liquid crystal materials
Inventor: BONNETT P
IPC: G01K11/16
Filed: 1989-02-10
Abstract: Surface temperature is measured using a nematic liquid crystal material (4) contained within elongated open pores (3) in a stretched plastics material layer (2) mounted on the surface being measured. Polarisers are arranged either side of the layer with their optical axis at a non-zero angle to the length of the pores. These polarisers may be in contact with or spaced from the plastic layer. The liquid crystal material is arranged to have a nematic to isotropic phase transition just above the temperatures to be measured. Just below this phase transition temperature the order parameter of the nematic liquid crystal material changes by large amounts. This is observed as a large change in colour due to the changes in optical retardation. Different nematic liquid crystal material compositions may be arranged in different areas of the plastics material layer to measure a wide temperature range. Small amounts, e.g. 1 to 10% of dichroic dye may be added to the liquid crystal material; in this case one polariser may be dispensed with. A reflector may be arranged on the surface to be measured and the temperature measured by reflected light. The device may be applied to a wind tunnel aircraft model to provide surface temperature profiles. The model may be of transparent plastics material. <IMAGE>

Title: Controlling fluid flow through extraction cartridges
Inventor: JOEL SIMON PETER
IPC: B01D11/04
Filed: 1990-02-06
Abstract: In the extraction of substances from body fluids the fluid passes under gravity and suction from a reservoir through a cartridge. At the junction between reservoir and cartridge an infra-red light emitting diode (10) and phototransistor (11) provide an optical path through which the meniscus of the liquid passes as the reservoir empties. When there is no longer fluid in the optical path, the output of the detector circuit rises above the reference voltage of a comparator (15) to reset a NAND gate (16) which therefore passes a signal at (20) to shut a solenoid valve interrupting the suction thereby preventing entry of air into the cartridge. Where a number of such assemblies are operated signals through lines (18) and a NOR gate (19) set a start switch which is then used to open the valves by setting NAND gates (17) assuming the NAND gates (16) have been set by refilling the reservoirs. <IMAGE>

Title: Combination of displacement pump or piston pump and displacement motor or piston motor
Inventor: DETTINGER WILLI W
IPC: F04B7/02
Filed: 1990-07-17
Abstract: The inlet and outlet valve arrangement (9) of a valve controlled displacement motor or piston motor (2, 5, 8, 9) which is drivable by a fluidic or hydraulic pressure medium is fluidically or hydraulically actuated by exploiting the pressure pulsations in the working chamber (4) of a displacement pump or piston pump (2, 4, 6, 7) coupled to the motor (2, 5, 8, 9) and which therefore runs in synchronism with the motor (2, 5, 8, 9). The pump is particularly for pumping brine in a reverse osmosis plant (25) used for desalination. Pressure pulsations in the pump working chamber (4) control, via a line (24), reversal of the valve arrangement (9) which directs spent brine from the plant to the working chamber (5) of the motor during the working stroke of the pump. In this way some of the pressure energy in the spent brine assists reciprocation of the pumping piston (2). <IMAGE>
