Inventor: YAHAGI TOSHIO
IPC: B60T8/1769
Filed: 1989-07-18
Abstract: In order to determine slip rates in an anti-lock braking system, vehicle speed is estimated independently on front and rear wheels of the vehicle on the basis of the lower of the front wheel speeds and the lower of the rear wheel speeds. …<??>In one embodiment, the vehicle speed on the front wheels is estimated on the basis of the higher of: (a) the lower of the front wheel speeds and (b) a value resulting from correction of the highest of all four wheel speeds to allow for inner and outer wheel speed differences during turning of the vehicle. A vehicle speed on the rear wheels is estimated on the basis of the higher of (c) the lower of the rear wheel speeds and (d) a value resulting from correction of the highest of all four wheel speeds. …<??>In another embodiment for a vehicle with front wheels driven the lower of the driven wheel speeds and both the higher and the lower of the follower wheel speeds are used in the calculations. …<IMAGE>…

Title: Sensor system eg for chlorofluorocarbons (CFCs)
Inventor: HOLMES MICHAEL JOHN
IPC: G01N27/70
Filed: 1989-12-15
Abstract: A sensor system compares a measurement of CFC concentration with a stored threshold value which varies with time according to predicted variations in the background concentration of CFCs, thus avoiding unwanted alarm output signals caused by high background values. A CFC detector 2a has a housing including a detection section 13 containing a sensor. A fan is also located within the housing, and forces air past the sensor at a known rate, ensuring that the quantity of CFCs present can be measured accurately. A sensor network includes a number of base stations, each connected to a central processor, to which sensors (2a-2c, 3a-3c, 4a-4c, Figure 1) are interchangeably connected. The sensors may be CFC detectors, or pressure or temperature sensors providing data relevant to the control of the heating or air conditioning system in a building. <IMAGE>

Title: Avalanche photodiode quenching circuits
Inventor: MOIR CHRISTOPHER
IPC: G01J1/44
Filed: 1990-04-12
Abstract: The circuit includes a photodiode (2), a current sensor (4) in series with the photodiode and a feedback or control sub-circuit (5) which on being triggered by the current sensor (4) causes a change in the voltage or current supplied to the photodiode (2). In a second circuit, a transformer (4) is connected with the primary winding in series with, and preferably on the high voltage side of, the photodiode (2). On onset of avalanche the rapid change of current generates a voltage pulse across the secondary winding of the transformer (4). This pulse is amplified and is used to quench operation of the photodiode (2). The transformer may be replaced by an optical isolator alone or in combination with a capacitor. The pulse can be amplified using either a high-speed/video amplifier (6) or a comparator. <IMAGE>

Title: Coated filler particles and method for making same
Inventor: SWEI GWO S
IPC: C08K9/10
Filed: 1991-05-01
Abstract: A composite filler material includes an inorganic core and a layer of crosslinked silicone elastomer covering the core and chemically bonded to the core. The core may be a glass, ceramic, metal or metal oxide, or a siliceous material, such as amorphous fused silica, talc and clay. The glass filler may be fibres or hollow microspheres. The composite filler may be prepared by reacting a monofunctionally terminated polysiloxane with a multifunctional silane to form a multifunctionally terminated polysiloxane, which is then reacted with a silane crosslinking agent to form a reactive silicone network, which is coated on the inorganic filler and cured. Alternatively, the composite filler may be prepared by reacting a first multifunctional silane with an inorganic filler particle to form a surface modified filler particle having free silanol groups thereon, reacting a second multifunctional silane with a mono-functionally-terminated polysiloxane to form a multi-functionally-terminated polysiloxane, which is then reacted with the silanol-groups on the surface modified filler particles to form a coating layer, which is then crosslinked. The composite materials can be used as fillers for thermoplastic and thermoset polymers e.g. fluoropolymers, polyolefins, polycarbonate, polyphenylene sulphide, epoxies, phenolics, polybutadienes and cyanate esters.

Title: Securing fixing clamp to support
Inventor: UNDERHAUG NJAL
IPC: F16L3/24
Filed: 1991-07-05
Abstract: A fixing clamp is provided for securing a pipe or cable to a support formed with oblong holes. The clamp includes a jaw portion having a groove to receive the pipe or cable, and a top plate hold in place by two bolts to retain the pipe or cable in the groove. The bolts serve also to secure the clamp to the supports, and for this purpose each has a shank threaded to receive a securing nut and a head extending transversely to the head and connected to the head through a cranked portion. The cranked portion is received in a recess in the jaw portion and the recess provides reaction surfaces engageable by the cranked portion to limit rotation of the bolt about the axis of the shank. The heads of the bolts can be passed through the oblong holes in the support and can then be rotated by rotational movement of the jaw portion to position the heads transversely of the oblong holes. The axis of the groove is preferably at an angle other than 90 DEG to a common normal to the axes of the shanks of the bolts. <IMAGE>

Patent GB-918814-A (GB)
Abstract: 918,814. Temperature-responsive actuating- elements. BENDIX CORPORATION. April 28, 1961 [May 2, 1960], No. 15394/61. Class 64 (2). A temperature-responsive control apparatus has a positionable output member actuated by a variable volume chamber 22 filled with a medium which expands or contracts according to variations in either of two temperatures, the member being mounted for movement about a pivot member 18 movably carried by a fixed supporting means, and a second variable chamber 42 also filled with a medium and responsive to only one of the two temperatures is connected to the pivot member 18 to move it in the supporting means to modify the lever arm length 14 of the output member, through which the chamber 22 acts as a function of the one of two temperatures, so that chamber 42 compensates for the variation of the chamber 22 due to variations in the one temperature. If the temperature of the probe 36 remains constant, but the temperature of the fluid surrounding the chambers 22 and 42 rises, then the chamber 22 expands so urging the lever 14 upward and pivoting it clockwise about the floating pivot pin 18. The expansion of the compensating chamber 42 urges the pin 18 upward, causing the lever 14 to pivot counterclockwise about the pivot 40, the resulting effect of the two movements being a counterclockwise motion of the lever about point A. The travel rate of the chamber 22 for a given change in the probe 36 temperature will vary depending upon the initial temperature and volume of the liquid in the chamber 22, and can be compensated for by varying the effective length of the lever arm from pin 40 to pivot pin 18. To this end, the pin 18 is restricted to movement along a path defined by milled slots 74 and 76 (Fig. 3). Thus as the pin 18 is urged upwardly it rides on bearings 70 and 72 along inclined walls of the slots 74 and 76, and moves sideways on the slot 64 away from pin 40, which increases the effective length of the lever arm between pins 40 and 18. The system may be calibrated by the adjustable feature on the support 20 and the rod 48 on the bellows 42. Springs 32 and 90 impose preloads against chambers 22 and 42, respectively.

Title: Mounting apparatus for satellite antenna
Inventor: CHARALAMBOUS GEORGE
IPC: H01Q1/12
Filed: 1992-05-21
Abstract: A television satellite antenna (2) is supported by two parallel rigid struts (1). Outwardly projecting portions (4) thereof are pivotally mounted respectively to a rigid member (5) and a flange (7) located at either end of a transverse bar section (6) which can be fixed relative to a support member (10). A first elongate member (14) is pivotally mounted to the rigid member (5) at one end with the other end pivotally connected to one end of a second elongate member (15) which is in turn pivotally mounted at one end to a strut (1). As a piston (17) pushes against the elongate member (14) relative to an extension (8) of the rigid member (5), the angle between the elongate members changes to cause rotation of the strut and antenna. <IMAGE>
