Patent GB-2246429-A (GB)
Title: Automatic vehicle light switching system
Inventor: DUNCAN PAUL ANGUS
IPC: B60Q1/14
Filed: 1991-05-24
Abstract: An automatic vehicle lighting system which operates a vehicles main headlamps (2) automatically in low levels of environmental light is designed to be incorporated into existing vehicle lighting systems and circuits. A light dependent resistor (1) in series with a relay (3) is exposed to environmental light as much as is possible. This could be in a recess in the bumper or bonnet of a vehicle (between the windscreen wipers) or centrally on the dashboard. As the environmental light level falls, the light dependent resistor conducts less current. Eventually relay (3) falls and the lights (2) are energised through contact (3E). The single pole switch (8) is intended to allow the driver to have the main lighting of a vehicle off whilst running the vehicle's engine at night. <IMAGE>

Title: Activated biocidal compositions
Inventor: SNOWDON GILLIAN PENELOPE
IPC: A01N59/16
Filed: 1991-07-13
Abstract: The capability of an organic peroxyacid to act as a broad spectrum biocide is boosted by incorporating an activating amount of a metal selected from iron and copper, thereby permitting a lower concentration or amount of the organic peroxyacid to be employed. Preferably, the compositions employed for this purpose exclude metal chelators. The compositions can be employed to treat a wide range of materials, including aqueous media, such as effluents and process waters, hard surfaces and growing or harvested plant materials. The peroxyacids include aliphatic peroxyacids such as peracetic acid and aromatic peroxyacids, possibly in salt form, such as magnesium monoperoxyphthalate. Other components which may be incorporated in the compositions include a bromide, iodide and/or alkyl sulphate surfactant which can likewise boost the biocidal performance of the organic peroxyacids.

Patent GB-2274867-A (GB)
Title: The automatic foldaway fire escape
Inventor: KELLIE FREDERICK JOHN
IPC: E06C9/08
Filed: 1993-01-19
Abstract: An automatic fire escape comprises an extension ladder housed in a housing in the wall of a building, the housing having a door hinged out of plumb to swing open under its own weight to automatically release the ladder. The ladder has handrails 15, which also come into position automatically and are intended to assist the elderly and/or children to descend safely.

Title: Battery pack with short circuit protection provided by semiconductor switching device
Inventor: HASHIMOTO HISASHI
IPC: H01M50/574
Filed: 1994-06-15
Abstract: Connection between batteries 2 and terminals 3 of the battery pack is controlled by semiconductor switching devices 1 e.g. FETs, so that when the battery pack is not connected, battery short circuits are prevented by non-conduction of the switching devices, and when the battery pack is attached to electrical equipment, a control circuit 4 detects attachment and turns the switching devices on to supply power to the equipment. If the electrical equipment is a battery charger, the switching devices are turned on to supply power to the battery pack. The control circuit may be an AND logic circuit having an output side connected to the switching device and the input side connected to an over-charge and over-discharge protection circuit 6 and to a signal terminal 7 receiving a signal from terminal 8 of the electrical equipment when the pack is attached. The switching device is thereby turned on and off by signals from signal terminal 7 and the protection circuit 6. In alternative arrangements the control circuit is provided with a detection switch (210 Fig. 2), a phototransistor (413 Fig. 4) or a microcomputer (616 Fig. 6) operating on a signal from a microcomputer in the electrical equipment. <IMAGE>

Title: Adaptive chrominance and luminance separator
Inventor: HATANO TAKAHISA
IPC: H04N9/78
Filed: 1994-10-11
Abstract: Comb filters 5, 6 separate the chrominance component, which is then subject to bandpass filtering 11, 12, from a composite video signal VBS using one line delays 2, 3. A correlation detector 15 controls weighted mixing of the two comb outputs and also controls weighted mixing of the a wide band 11 and narrow band 12 bandpass filtered chrominance components to output a separated chrominance component. The wide band filter 11 is selected when there is high correlation between lines of the composite video signal, and the narrow band filter when little correlation is present, giving a good colour transient characteristic (in the presence of correlation) but avoiding cross colour interference. <IMAGE>

Patent GB-2293257-A (GB)
Title: Fire alarms
Inventor: KHELLAF FARIZ
IPC: G08B17/00
Filed: 1995-09-12
Abstract: Warning devices such as sounders 36 are connected in a common circuit with fire detection devices 34. The detection devices operate within a first voltage range and the warning devices operate within a second voltage range, the two ranges having the same polarity. There is a non-sounding voltage within the first range but outside the second range which does not operate the warning devices. In use the system normally supplies power to the circuit at the non-sounding voltage to power the detection devices. During an alarm condition the circuit is supplied with a voltage within the second range, this causing the warning devices to activate. Preferably there is an alarm voltage which is within both ranges thus enabling the detection devices to remain active during an alarm condition. <IMAGE>
