Patent GB-2315032-A (GB)
Title: Electrostatic electrode assembly
Inventor: BALLARD DENNIS
IPC: C02F1/48
Filed: 1996-07-05
Abstract: A probe for treating electrostatically a liquid e.g. water, comprises a tubular electrode element 11 made of aluminium, having a threaded portion 14, a polyolefin sheath 16, a threaded insulating cap 18 which seals the sheath, a mounting end cap 30, an electrode terminal 40 and a plug body 50 of PTFE. When the element 11 is screwed into the end cap 30, the contact plate 60 is urged into compressive engagement with the end 45 of the terminal. The shoulder 39 allows the device to be mounted in a vessel wall, a nut being located on the threaded portion 38. O-rings 27 and 56, and PTFE tape at 14 and 18, are used to seal the device. Since the sheath is made of polyolefin it discourages build up of deposits thereon.

Title: Calibrated battery tester
Inventor: ROBERTSON RUPERT EDWARD
IPC: G01R31/00
Filed: 1997-01-30
Abstract: A battery testing circuit is built into an aluminium heatsinking box, and has inputs for specific Ah ratings of Rechargeable Sealed Lead Acid batteries. The fully charged battery is connected in parallel with a separate calibrated digital Voltmeter, c 5% accuracy, and resistive load. An o.c. 12V battery passes the test if the voltage stabilises at the 90% threshold voltage of * <------ solidus * 10.8V for a minimum of 60 seconds. If the voltage * <------ solidus * 10.8V, the current flowing will be * <------ solidus *  the battery's Ah rating A c 10% variation in current provides sufficiently accurate results. As the test has been carried out using a specific load, duration and calibrated Voltmeter, batteries 'passing' can then be considered reliable for their application. Batteries 'failing' have outlived their useful life and can be confidently discarded or at least considered unreliable.

Title: Safety device switch for vacuum cleaner power brush
Inventor: JUNG YOUNG-JUNE
IPC: A47L9/04
Filed: 1997-09-12
Abstract: A safety device for a power brush of a vacuum cleaner has a simple structure and can automatically cut off an electric source supplied to the driving motor of the power brush. A cylindrical air duct 324 is vertically provided on the brush. The air duct is attached to the body of the cleaner 322. A negative pressure generated by a sucking force generated by the rotation of the driving motor in the body of the cleaner acts on the air duct. An air valve 328 moves inward by the negative pressure in the air duct. At a first end of a rod, the air valve is mounted and at a second end facing the first end, a spring for applying a rotating force to move the air valve to an external direction, is provided. The rod is movably supported by a moving shaft provided near the outer periphery of the air duct. A switch is provided at the second end side of the rod having the spring. The switch is off to cut off the electric source applied to the driving motor of the power brush to prevent the rotation of a rotating roller when the air valve moves to the external direction by the action of the spring. Accordingly, when a user does not use the vacuum cleaner, various safety accidents induced by the rotating force of the power brush can be prevented.
Patent GB-2317950-A (GB)
Title: Structure defect detection
Inventor: YAMAZAKI KENICHIRO
IPC: G01N33/38
Filed: 1996-08-02
Abstract: To detect a defect in a structure eg a bridge 31, the infra red radiation emitted from the surface of the structure is measured 2 during the daytime and at night. The difference between the spatial temperature distributions for day time and night time is calculated and defects are determined to be present when this difference exceeds a predetermined value eg 0.3{C. Areas of a structure where a defect exists will not conduct heat efficiently and will be at a higher temperature during the day and at a lower temperature during the night than surrounding areas of the structure. Determining the difference between the day time and night time temperature distributions enhances the temperature variations caused by any defects making their detection easier.

Title: Circuit module for a phased array radar
Inventor: DEAN MICHAEL
IPC: G01S7/28
Filed: 1995-07-07
Abstract: A circuit module for a phased array radar (10) incorporates radar frequency (RF) mixers (54a, 54b) connected to an RF splitter/combiner (52) and to in-phase and quadrature RF reference signals. The RF mixers (54a, 54b) are also connected to intermediate frequency (IF) processing circuitry (60 to 68) providing for phase control of RF signals and IF reference signals. In transmission mode, the RF mixer (54a, 54b) receive phase-controlled, digitally synthesised IF signals from clock-activated generators (68a, 68b). Their outputs are combined at the RF splitter/combiner (52) to provide single sideband upconversion of the phase-controlled IF signals. In reception mode, the RF splitter/combiner (52) and the RF mixers (54a, 54b) act as an image rejection mixer circuit in which the phase-controlled IF signals are local oscillator signals. Beamforming is carried out by computer control of the IF phase together with, in the case of reception, analogue or digital summation of output signals from an array of modules (12).

Title: Adjusting means for a movable member
Inventor: LAMM HUBERT
IPC: G05B19/23
Filed: 1997-12-12
Abstract: The device for moving a member such as a tilt and slide sunroof 11 comprises a drive means 10, a displacement encoder 15 and at least two absolute position transmitters 16, 17, each of which gives a signal in either of two switching states, and means 27 for determining the position of the movable member from the outputs of all the transmitters, and preferably also from the direction of rotation of the motor. The absolute position encoders may be cams 22, 23, 31, 32 and switches 25, 33. As described, one of the absolute position transducers defines a position adjacent the closed position of the sunroof, and the other defines the open position(s). After settings have been lost, an initial, safe, direction of the motor can be determined from the outputs of the absolute position sensors, and subsequent movement will produce further position signals from which the position determined by the displacement encoder output can be referenced.

Title: Immunoassay testing
Inventor: BALDWIN DENE
IPC: G01N33/543
Filed: 1998-07-14
Abstract: A screening device for performing an immunoassay test to detect the presence of a compound in a body fluid. The device includes a holder for removably receiving a membrane to which the fluid has been applied. Light is directed to the membrane. A photodetector measures the concentration of the light reflected back from the membrane. Specifically, the concentrations of reflected light from a control zone and a test zone are measured. Signals representative of the measured light concentrations are applied to a processor. If a specified concentration of predetermined light from a control zone on the membrane is detected, the processor considers the test to be successful. In the test is successful, the processor, based upon the measured concentration of reflected light from the test zone, generates data representative of the presence of the compound.
