Title: A wide bandwidth rf spectrum analyser
Inventor: DAWBER WILLIAM
IPC: G01R23/17
Filed: 1992-03-26
Abstract: A broadband electrical signal spectrum analyser comprises a spatial light modulator such as a Bragg cell (22) located within at least one resonant cavity and illuminated by a polychromatic source of light (20). The signal to be analysed is connected to the Bragg cell (22). The tuned cavity is arranged to lase the diffracted light to thereby enhance the signal before detection. In one arrangement the cavity is formed by opposed mirrors (23, 24) set at the Bragg angle and one of the mirrors is oscillated through a range of frequencies required by the broadband application. In a second arrangement a plurality of narrow band channels is formed by a fibre optic array. The fibres are arranged such that first ends of the fibres form a linear input array (41) and the second ends form a linear output array (42). Light at the Bragg angle passes into an appropriate one or more of the output array fibres, passes around the looped fibres to the input array where the light (zero order) is transmitted through the Bragg cell and then back to the fibre loop. A collimating lens (44) is provided on the input side of the Bragg cell and a Fourier transforming lens (45) is provided on the output side of the Bragg cell such that the position of the optical fibre in the array carrying the diffracted light is frequency dependent and the amount of light depends on the amplitude of that frequency in the electrical signal.

Patent GB-2265186-A (GB)
Title: Valve actuator
Inventor: EVANS DAVID RICHARD
IPC: G05D23/19
Filed: 1993-02-25
Abstract: An actuator for a valve comprises an actuation member 16 movable from a first position to a second position in response to pressure variation in a chamber 12. Pressurising means is arranged to selectively vary the pressure in the chamber, the actuator further being provided with detent means see fig 4 arranged to hold the actuation member in the second position subsequent to a first operation of the pressurising means and permit the actuation member to return to the first position subsequent to a further operation of the pressurising means. Movement of the actuation member may be used to open or close a valve, which valve may form a part of a central heating system. The pressurising means may take the form of a heater 30 which raises pressure in chamber 12 and causes member 16 to activate a valve, eg in a central heating system. To obviate the need to continuously operate heater 30 to keep the valve in its desired position the detent mechanism holds it in this position even when the heater is switched off. Subsequent operation of the heater causes the member 16 to be unlocked from the detent means and movement to the first position is then possible. <IMAGE>

Title: Detecting passage of cleaning liquid in a beer line
Inventor: MORGAN PHILIP DAVID
IPC: B67D1/07
Filed: 1994-03-08
Abstract: A logger is adapted to be located in a beer line of a draught beer installation. The microprocessor-based circuitry of the logger 10 continuously monitors liquid passing through the beer line. When the beer supply is removed and a cleansing solution is passed through the line, a sensor of the logger senses a parameter change. The logger can record and store the dates and times when cleansing operations are carried out. Accessing the monitored information is by way of an interrogator device (Fig. 2) which is removably connectable with the logger, this therefore obliging the operator of the beer line to perform the required line cleaning operations. <IMAGE>

Title: An antitheft vehicle door lock
Inventor: YAMAZAKI TAKEHIKO
IPC: E05B81/56
Filed: 1994-04-13
Abstract: An antitheft apparatus for an automotive vehicle includes: door lock mechanism (110); constraining (stopper) members for constraining the door lock mechanisms; once actuated to a lock status so as not to be unlocked; a set switch (125) for outputting a constraint command for constraining the door lock mechanisms; and a controller responsive to the constraint command outputted by the set switch, for first locking the doors by the door lock mechanisms and then constraining the door lock mechanisms to the lock status by use of constraining members. When the command for constraining the door lock status is outputted, since the doors are first locked by the lock mechanism and thereafter the lock mechanisms are constrained to the lock status, even if the door is unlocked after the doors have been locked, it is possible to securely constrain all the doors to the lock status. An ignition device may be provided for connecting and disconnecting a current supply to the starter motor in response to the constraint command. <IMAGE>

Title: Piolt operated valve assembly
Inventor: WU CHAI-TIEN
IPC: F16K7/10
Filed: 1995-09-28
Abstract: A pilot operated valve assembly includes a rigid casing (10), an expandable and retractable hollow valve body (20) and a control device. Casing (10) includes a peripheral wall (11), and an inlet (13) and an outlet (12) formed through peripheral wall (11) to define a valve-accommodating space therebetween. The valve body (20) made of a flexible water-impermeable material is disposed in the valve-accommodating space such that the valve body (20) cooperates with an inner surface of the peripheral wall (11) to define a clearance (22) to permit flow of water from the inlet (13) to outlet (12). The control device can be actuated to expand the valve body (22) to different degrees in order to reduce the clearance (22), until no clearance (22) occurs between the valve body (20) and the peripheral wall (11), thereby closing sealingly the inlet (13A) and the outlet (12A) to prevent water flow therebetween.

Title: Addition of carbon suspension obtained by electrolytic oxidation of carbon to lead-acid battery electrolyte activates electrodes when charged
Inventor: FUJITA KENICHI
IPC: C01B31/02
Filed: 1995-09-28
Abstract: A colloidal suspension of carbon obtained by electrolytic oxidation of a carbon anode in e.g. water such that the surfaces of the particles are chemically modified with hydrophilic groups e.g. carbonyl, carboxyl, hydroxyl is used as an additive to the electrolyte of a lead-acid battery to activate the PbO 2 cathode by electrochemcial doping. Doping is achieved by continuous charging of car batteries during running of the car, or performing charging prior to use. The battery shows: (i) high charge current without extraordinary increase in the temperature; (ii) high discharge current; and (iii) the increase in the lifetime of the battery. This process is applicable for the revival of degraded batteries and formation treatment of electrodes of new batteries.

Title: Lithium niobate devices
Inventor: DONALDSON ALAN
IPC: G02F1/03
Filed: 1995-10-19
Abstract: A lithium niobate device having one or more optical waveguides, is hermetically sealed within a package containing an atmosphere that includes at least 0.5% by volume of water vapour. A primary reason for prior art hermetic sealing of such packages has been to preclude moisture ingress leading to catastrophic electrical breakdown, but excessively dry an atmosphere is found to aggravate problems of bias voltage drift. The device may be a Mach Zehnder optical modulator.
