Title: Temp. compensated silicon@ capacitive accelerometer - suspends seismic weight between counter electrodes such that one electrode gap narrows whilst electrically-parallel gap widens with temp. to cancel capacitance fluctuations
Inventor: BLEY PETER DR
IPC: G01P1/00
Filed: 1992-08-10
Abstract: The sensor contains an inertial wt. (2) suspended on a bearing block via a flexural tongue to vibrate in a preferred plane and simultaneously act as an electrode of a capacitance sensor. Counter electrodes (6-9) attached to the block about the inertial wt. form a capacitive system. The counter electrodes, whose distances (11-14) from the wt. vary in the same sense with movement, are connected in parallel.  As the temp. varies one gap decreases and an electrically parallel one increases so as to compensate for the change. The length and/or gap width are matched so that capacitance variations with temp. are negligibly small. USE/ADVANTAGE  - E.g. for monitoring movement of machine parts. Capacitance changes caused by temp. variations are minimal and negligible both in null state and during acceleration. Broadens scope of use.

Title: Prodn. of porous coatings on thermoplastic mouldings - by drawing aerial suspension of particles onto and through sintered mouldings, using e.g. similar types of polymer for both materials
Inventor: RAUSCH WALTER DR ING
IPC: C08J9/36
Filed: 1992-10-02
Abstract: Open-pore sintered thermoplastic mouldings are given a porous surface coating. The particles of the coating material are fed into an air current, the aerial suspension is fed to and drawn through the sintered moulding, the particles remain on the surface, partly entering the outer pores. When the required thickness of coating is reached, as measured, e.g. by loss of pressure, the feed of particles is stopped by cutting off the air current and the particles on the moulding are bonded together by sintering, by adhesive or by welding, etc. and are bonded to points on the moulding. ADVANTAGE - The method is flexible and can suit various different conditions, e.g. by adjusting the fineness of the particles or the e.g. flow speed of the current.

Title: Extra-low density plastic syntactic foam - consists of mass of hollow polyhedric particles plus binder with very few intermediate gussets of adhesive
Inventor: BURGER HANS-JOACHIM
IPC: B29C70/66
Filed: 1992-10-23
Abstract: Moulded microspheres type syntactic foam has its particles bonded in a matrix of adhesive; the hollow microspheres used are polyhedra held together in sheets by the matrix adhesive with much reduction in the gusset wedges of adhesive. The microspheres are pref. polyvinylidene chloride, polyvinyldiene fluoride, polymethylmethacrylate. Pref., the figure shows the structure obtained, in which the individual particles are polyhedra (1). They are pressed together with their adhesive (2) which prevents relaxation into the other structures. To produce the foam concerned the microspheres (1) and adhesive (2) are mixed together and then tumbled. This is followed by a curing phase. Many types of adhesive can be used e.g. polyurethane, urea-formaldehyde, polyester, epoxy, acrylic, etc. Foams with glass microspheres are less favourable because they are less easy to mould and they contain gussets of adhesive. ADVANTAGE - The prod has significantly lower density than such materials hitherto (e.g. 25-300 kg/m3 instead of 450 kg/m3). The foam concerned is closed-cell, water-tight, solvent-resistant and fine-pored. Use of the pref. polymers enables the products to have thin walls and good elasticity. The process if very versatile.

Title: Workpiece treatment with gas stream - is used esp. for hot gas drying of lacquered cans, using pressure drop to stabilise cans on moving support
Inventor: RADEWAGEN KLAUS ING GRAD
IPC: F26B15/18
Filed: 1992-11-21
Abstract: The workpiece is treated with a gas stream by passage through a treatment zone on a gas-pervious support and with a view for treatment with hot gas stream in a drying furnace.The gas stream is sucked away with increased velocity so that a gas pressure drop is created for pressing the workpieces with their standing faces onto the support. The  support is a flat transport belt which has passage openings for the gas stream and which moves transversely to the direction of the gas stream.The gas stream is supplied above the workpieces and is sucked away below the support. ADVANTAGE - The pressure drop provides stability of the workpiece on the moving support so that increased gas flow velocities can be used to obtain rapid drying.

Title: Hydraulic circuit for garbage truck
Inventor: HILMER GUENTER
IPC: F15B11/16
Filed: 1992-12-22
Abstract: A commercial vehicle like a garbage truck has a hydraulic circuit with actuators for different functions, like opening the tail gate, lifting and tipping of the garbage container, etc. There is a motor or auxiliary drive from the vehicle's engine for the oil pump, delivering to the circuit. The pump output can be controlled independently of the motor speed. The control device evaluates the load requirement of all the actuators and adjusts the pump output so that the motor speed is as low as possible, and is only increased if extra output is needed. This minimum speed is optimally the idling speed.

Title: Closed from surveillance system - monitors opening or destruction of doors or windows and movement of people in room and sets off alarm
Inventor: MEYER DIRK
IPC: G08B13/16
Filed: 1993-02-05
Abstract: The system includes an electronic amplifier (2) for frequencies in the sonic range. If desired, the amplifier (2) can extend to the infrared or ultrasonic ranges. The amplifier (2) has a sound sensor (1) at its input and a sound generator (3) at its output. An electronic analyser circuit (4) detects signals from the room fed back from the sound generator (3) to the sensor (1). When these signals vary outside a given tolerance window, the analyser (4) triggers an alarm (5). Variations which are only based on sound events without changing the sound characteristics of the room can be filtered out or can be detected by a comparison with the signal of a further separate amplifier and can be excluded by the alarm generator (5). ADVANTAGE - Can be easily installed in room to be monitored independent of mains power supply with reliable alarm operation. Simple and inexpensive to manufacture with high degree of integration.
