Title: Supply fluctuation compensation system
Inventor: HENDERSON ROBERT C
IPC: G05B11/28
Filed: 1996-07-22
Abstract: In a control system 206 providing servo control of an active device 14 eg a valve, the gain of the control loop is adjusted to compensate for low frequency variations in the supply voltage. The low frequency component of the supply voltage is sensed by a sensor 32 and the gain adjusted in inverse proportion to the sensed low frequency component. High frequency components are removed by a series pass element 22. The power in the drive signal is therefor made independent of variations in the regulated supply line voltage. As a result, the active device is operated with greater efficiency and accuracy.

Inventor: PAETH KARSTEN
IPC: F16D25/08
Filed: 1996-10-29
Abstract: To prevent vibration of the clutch pedal of a hydraulic clutch actuation system as a result of low-frequency vibrations applied by the clutch to the liquid column and propagating in the latter as a low-frequency pressure pulsation, an auxiliary vibrator (20) is provided in the liquid column and is excited by the low-frequency pulsation in such a manner that it vibrates with its intrinsic frequency, which is higher than the frequency of the low-frequency pressure pulsation, so that the auxiliary vibrator (20) induces, in the liquid column, a higher-frequency pressure pulsation, which does not vibrate the pedal. The auxiliary vibrator (20) possesses a freely vibrating diaphragm (28), which is clamped in a housing in order to form its base and/or lid.

Title: Panel and barrier system incorporating same
Inventor: MOORE JOHN
IPC: E01F8/00
Filed: 1997-05-13
Abstract: A panel for use in a noise barrier system has upper and lower edge surfaces formed by extrusions (13, 14; ), the upper extrusion defining a projection (18) having a convex outer surface (19) and the lower extrusion defining a recess (21) with an outwardly facing concave surface.

This enables one panel to be arranged at an angle to its adjacent panel instead of normally being aligned therewith, so as to enable a curved barrier system to be provided. Instead of the engagement between adjacent panels being by curved surfaces, it can be between a triangular projection (26) and a V-section recess (27), Figs 5, 6. Seals 24 prevent noise passing through the joints.

Patent GB-2328797-A (GB)
Title: Liquid level float switch
Inventor: BARDOLF-SMITH JAMES LINCOLN
IPC: G01F23/70
Filed: 1997-08-30
Abstract: A liquid level float switch for automatically switching on an electrical pump to fill a tank when it is empty and for switching off the pump when the tank is full comprises a rigid tube 10 mounted vertically within the tank, a float valve 13 located at the top of the tube 10, a float 16 movable within the tube 10 and connected to a pump switch 19 positioned above the maximum liquid level via a U shaped rod 17 which passes through a slot 12 extending 100 mm up from an open bottom end of the tube 10. When the liquid level falls, the float valve 13 closes and a vacuum forms in the top of the tube 10 to maintain a liquid column in the tube 10 which supports the float 16 to retain the pump switch 19 in the off position. When the tank nears empty, the slot 12 in the tube 10 is opened to atmosphere to release the vacuum causing the float 16 in the tube 10 to fall and the pump switch 19 to be turned on. As the liquid level rises, air is trapped in the tube 10 to prevent the float 16 from rising. When the tank is full, the float valve 13 opens to release the air pressure in the tube 10 to allow the float 16 to rise in the tube 10 and the pump switch 19 to be turned off.

Title: Lift door protection apparatus with power saving circuitry
Inventor: BAILEY PETER LESLIE
IPC: G01V8/20
Filed: 1998-10-13
Abstract: Infrared transmitters 3 and receivers 5 positioned on opposite lift doors 1a, 1b detect obstruction between the doors and reopen the doors if necessary. Circuitry connected to the receivers determines the position of the lift doors and reduces power supplied to the transmitters when the doors are closed or nearly closed and restores power when the doors are open. The power reduction is achieved by increasing the interval between sequential activation of the transmitter. This also increases the lifetime of the infrared transmitter diodes. A further embodiment reduces power to the transmitters only after a predetermined delay period following door closure.

Abstract: An optical power divider comprising an input optical waveguide, and a plurality of output optical waveguides, and a beam separator (400) located at a branch area in which light incident on the input optical waveguide diverges toward the output optical waveguide. The beam separator (400) separates the light to the output optical waveguides with a predetermined ratio, and is made from a material which has a lower refractive index than the core of the input and output optical waveguides. Beam expanders (410) may also be provided at positions near the outer sides of the branch area for dividing the light to be output uniformly. The beam expanders (410) may be made from a material which has a higher refractive index that the cladding region of the input and output optical waveguides. The beam separator (400) may have a triangular shape where the output light is separated in a predetermined ration according to the refractive index, and the height and the length of a side of the triangle. The optical power divider may take the form of a 1x4 optical power divider, and the refractive index of the beam separator (400) may be the same as that of the cladding region of the input and output optical waveguides, and the refractive index of the beam expander (410) may be the same as that of the core of the input and output optical waveguides. Such an optical power divider has a much less complicated structure, where energy loss is greatly reduced, partly by reducing the overall length of the structure, and also reducing the number of branch areas and branch points. Methods of fabricating such an optical power divider are also disclosed.
