Title: Pressure sensor
Inventor: MAREK JIRI
IPC: H01L29/84
Filed: 1991-08-14
Abstract: A pressure sensor has a silicon sensor element 10 on the two main surfaces of which covers 21, 22 are applied. The silicon sensor element has at least one thin, bendable diaphragm 11, the first surface of which is adjoined by a reference cavity 26 in which a reference pressure prevails, and the second surface of which is adjoined by a measuring cavity 15 so that the pressure to be measured acts on the second surface of the at least one diaphragm. The pressure food into the measuring cavity is formed laterally between one of the two covers and the silicon sensor element, by a trench 13 etched in the sensor element 10, or by a groove 23 in the cover 22.

Title: Torsionally-resilient damper for motor with worm gear
Inventor: MATSUMOTO TSUTOMU
IPC: E05F15/16
Filed: 1991-09-10
Abstract: A damper device for a worm wheel (1) meshingly engaged with a worm on a motor shaft and driving a rotatable torque transmission disk (2) connected to an output shaft has a resilient damper/coupling member (3) interposed between the worm wheel (1) and the torque transmission disk (2) so as to transmit a torque of the motor to the output shaft. Protrusions (22) of the torque transmission disk are loosely fitted respectively in recesses (101) in a flange (10) of the worm wheel. With this construction, when a large load is applied to the output shaft, the protrusions (22) are abutted respectively against the edges of the recesses (101), thereby preventing an undue deformation or twisting of the damper/coupling member (3). The drive is used to operate a power window in an automobile. <IMAGE>

Title: Rotational speed sensing device integrated in a wheel hub bearing
Inventor: CAILLAUT CLAUDE
IPC: G01P3/487
Filed: 1992-01-08
Abstract: Device for sensing the rotational speed of a rotating element (4) mounted by means of a rolling bearing on a non-rotating element (3), comprises a multipolar ring (17) which rotates with the element (4), a sensor (19) which is made integral with the non-rotating element (3) and magnetic flux concentrating means arranged in the immediate vicinity of the multipolar ring and cooperating with the sensor in order to concentrate and channel the magnetic flux emitted by the multipolar ring. The flux concentrating means is of annular shape and comprises at least a first end shield (24) having a radial part of which one circular edge is provided on its circumference with a sealing lip (25) coming into contact directly or indirectly with the rotating element (4), and a second end shield (26) provided with radial teeth (27) spaced regularly along a circular path, and the multipolar ring is axially magnetised and arranged in the axial space included between the radial pan of the first end shield on the one hand, and the radial teeth of the second end shield on the other hand, so that the radial teeth are all situated axially opposite magnetic poles of the same polarity of the multipolar ring. The device thus provides a high electrical output and is insensitive to air-gap variations. The sensor may be a coil, Hall device or magnetoresistor. Various arrangements of the seal (25) and flux concentrating shields are described, and ways of attaching plastics ring (21) which houses the sensor. <IMAGE>

IPC: F21V23/04
Filed: 1992-05-21
Abstract: A lamp holder for a decorative string or Christmas tree light assembly comprising a base having first and second portions (1, 2) with a switch (21, 110, 111) at a bottom of the first said base portion. The switch has two opposite electrical contacts (110, 111) connected respectively to the electric circuit (130, 131) of a decorative string or Christmas tree light assembly.

Title: Air pump.
Inventor: SOHN TONG-HOON
IPC: H02K33/18
Filed: 1992-07-07
Abstract: An air pump 1-1 is disclosed which is designed to supply air for biasing the cone of a loudspeaker. The pump is formed with a container 10 housing magnetic circuit parts 1, 2, 5, 18 which create a magnetic field through which a coil 3 and thus bobbin 4 are driven by the passage of an a.c. current. The bobbin is connected to a piston plate 11 via a rod 9. A cylindrical bellows 8 is positioned between the rim of plate 11 and the rim of the container 10. Air inlet and outlet valves, 6 and 7 respectively, are located in the plate 11. Oscillatory motion of the coil, and thus plate 11, produces a corresponding flow of air through valves 6 and 7, providing the biasing air. The device is designed to have a weight advantage over similar devices. Single and double triangular bellows pumps are also described, Figs 3 - 6 (not shown). <IMAGE>

Title: Thermoinsulative protective clothing system
Inventor: MIDDLETON NIGEL JOHN
IPC: A41D31/00
Filed: 1992-09-09
Abstract: The clothing system, Fig. 3, comprises an inner layer of thermal insulative material, such as neoprene, and an outer layer which may, inter alia, be waterproof and vapour permeable. The inner layer is provided with dome-shaped, vented air pockets and with an inner lining. When the system is applied to a protective suit, the outer layer provides protection, e.g. against rain, wind, fire, chemicals and radiation, whereas the inner layer functions to allow vapour transfer from the wearer, through the domes and into the air space between the two layers, wherefrom the vapour can then leave via the permeable outer layer. However, upon immersion in cold water, the water pressure closes the vents in the domes, Fig. 5, to maintain the thermal integrity of the insulation. Ideally, the suit will cover the whole body except the face. The domes need not be vented in some instances. The system provides some degree of buoyancy and can be used in jackets, trousers, gloves, shoes and balaclava. <IMAGE>

IPC: A47G29/14
Filed: 1992-10-15
Abstract: A milk bottle holder 1 comprises a holding portion 2, 3, 4 for holding milk bottles which is open at at least one side to permit the bottles to be manually grasped for removal from the holder, and a top protector portion in the form of flaps 13, 14 which are pivotable from protection positions in which the flaps 13, 14 are positioned immediately above the tops of the bottles to removal positions in which the flaps 13, 14 are pivoted away from the tops of the bottles to permit removal of the bottles from the holder. The flaps serve to prevent birds from perforating the tops of the milk bottles when in the protection position, and thereby avoid contamination of the milk.   <IMAGE>
Patent GB-2273213-A (GB)
Title: Thermal protection of electronic devices
Inventor: TALBOT KEVIN TREVOR
IPC: H02H5/04
Filed: 1992-12-05
Abstract: A control chip 10 controls an internal load 12 and an external load 14 via switch devices 16, 18 mounted on a common die. The characteristics of the switch devices are temperature dependent. The voltage Vx at the input to one of the switch devices 16 is monitored by the control chip which turns off the power to the external load on detection of a pre-determined change in this voltage. Such a change may be caused by an increase in the temperature of the switch devices due to, for example, a short in the external load. <IMAGE>

Filed: 1992-12-07
Abstract: A process for smoothing fluctuating electrical power output from a wind farm 1 includes an electrolysis plant 5 comprising cells for converting water into hydrogen and oxygen using DC output from the wind farm. Voltage dependent switch means (Figure 2) are used to ensure that the output from the wind farm is supplied to the optimum number of electrolysis cells, depending on the operating voltage of those cells. Hydrogen from the plant 5 may be compressed by a compressor 6, passed through a purification plant 7 and then into storage means 8. The hydrogen may then be used as a fuel (with oxygen from a storage means 15) in a steam turbine plant 21, 22 gas turbine plant 24, internal combustion engine plant 23, or fuel cell 25 in order to generate electricity to supply to a grid 3. Part of the hydrogen and oxygen supplied from the electrolysis plant 5 may be liquefied (plants 9, 16) for use elsewhere. <IMAGE>
