Title: Vacuum-assisted servo brake - has snap action device to hold two telescopic housings together
Inventor: LIND KLAUS
IPC: B60T13/52
Filed: 1989-11-23
Abstract: The vacuum-assisted servo brake for a motor vehicle has vacuum chamber housing (7) with a sealed piston and two sealed telescopic housings (2, 4) which fit one inside the other. The brake pedal actuates a rod (14) which acts on the valve piston (16). The two housings are fastened together by a device which seals the two pistons but which permits a limited degree of relative axial movement between the two housings (2) and (4). The device which holds the two housings (2) and (4) together operates with a snap action when the two parts are assembled. USE - Vacuum assisted servo brakes.

Title: Measuring unit for specific gravity - measures upthrust on floating body to avoid wave and surface tension effects
Inventor: BRAEUTIGAM WILFRIED
IPC: G01N9/12
Filed: 1990-04-12
Abstract: For measurement of the specific gravity of a liquid, a defined floating body is used and the upthrust acting on it is measured, through action on a diaphragm or a spring in a measuring path. The upthrust is thus converted into a mechanical indication or is electronically transformed to produce an indication, allowing incorporation in automatic control circuits. ADVANTAGE - Interfering effects of wave movement or surface tension are avoided.
Patent DE-4012271-A1 (DE)
Title: Speed control circuit for engine
Inventor: FUKUI WATARU
IPC: F02P5/15
Filed: 1990-04-17
Abstract: The engine has a sensor to monitor the crankshaft rotation and a processor circuit to determine the actual engine speed at each firing pulse. The mean engine speed is computed from previous measurements using a programmed averaging factor. The mean value is compared with a programmed idling speed and the timing is adjusted to maintain the idling speed. The microprocessor computes the correction to the timing signal. A programmed time delay in adjusting the timing prevents sudden changes due to transients.
Patent DE-4014079-A1 (DE)
Title: Protection of three=phase motor against asymmetrical faults - improves security of contact protection and prevents consequences of phase angle without dependence on circulating current
IPC: H02H7/08
Filed: 1990-05-02
Abstract: The motor is disconnected from the mains by a magnetic switch in a so-called AAC circuit subdivided into three sections. A signal convertor produces a DC voltage proportional to phase current of the motor. A difference indicator and amplifier serve as a responsive element for asymmetrical loading. A final amplifier acts as a contact relay. When the load exceeds 33 percent the circuit is brought into operation for 20 to 33 percent asymmetry. USE/ADVANTAGE - In conjunction with traditional motor protection, measures are effective against all asymmetrical faults, with active contact protection within 100 ms.

Title: IC engine load determn. - by air flow comparison w.r.t. reference quantity established for conditions, giving ratio of actual and possible individual cylinder flows
Inventor: WEINGAERTERN REINER
IPC: F02D41/24
Filed: 1990-06-12
Abstract: Fuel is injected through valves (21-24) into individual cylinders drawing air through an inlet manifold (9) from a throttle (5) equipped with a position detector (7) and preceded by an air flowmeter (6). The idling position of the throttle (5) is signalled by a switch (18). The controller (12) responds also to engine (13) temp. (10), speed (16) and crankshaft angle (19). Comparison of actual and ideal air flows produces a correction factor for use in determining the load. ADVANTAGE - Method is independent of constructional measures and free from errors in magnitude and direction due to pulsatile flow into inlet manifold.
Patent DE-4018925-A1 (DE)
Inventor: HUGO FRANZ
IPC: F27B14/00

In order to improve the microporous nature, the melt contained in the mold receptacle 4 is compressed by means of a pressure which is build up in the mold receptacle 4 prior to the cooling.
Patent DE-4021309-A1 (DE)
Title: Process thermally breaking down chemical and treating toxic residues - has number of indirectly heated fluidised bed incinerators used in series to provide efficient disposal of harmful chemicals
Inventor: HARTUNG LOTHAR DIPL ING
IPC: A62D3/40
Filed: 1990-07-04
Abstract: The materials are broken down in a number of indirectly heated fluidised beds in which aluminium oxide particles are kept in motion by a gas stream. The material to be treated is introduced in a number of pulses, and the bed temperature is maintained between 700 and 1000 degrees C. Any substances condensing in the bed are removed by a periodic flow of oxygen rich gas. The dwell time in the bed is calculated so that any oxygen can react with hydrogen molecules, halogens can react with hydrogen to form halogenated hydrocarbons, and aromatic hydrocarbons can be broken down into short hydrocarbon chains. Aluminium oxide particles above a certain size are returned from the outlet system to the fluidised bed, and other solid materials are separated or are further treated in subsequent treatment stages. The purified gas is separated from halogen containing and other residual materials by a water wash. USE/ADVANTAGE - This invention is used in the disposal of dangerous chemical substances by thermally breaking them down into easily treatable components. Currently used systems suffer from the disadvantage that un-broken down chemicals can adhere to soot or dust particles in the process exhaust and so escape from the system. The exhausted material therefore requires further treatment to cater for this. The efficiency of the proposed process is such that further treatment of the residual material is not necessary.

Title: Appts. for sensing adjustment of variable impedance device
Inventor: MOSELEY ROBIN C
IPC: H01C10/50
Filed: 1990-07-31
Abstract: The variable impedance device has an integral switch. As the variable impedance device is adjusted, a wiper alternately operates the switch between open and closed states. This is detected to indicate when the device is being adjusted. The device comprises an elongated resistive element and an elongated switching element mounted co-extensively and parallel to each other. A conductive sliding wiper is operable to electrically connect both elements at any point along their respective lengths to corresp. elongated conductive elements. The switching-element comprises a series of conductive areas that are electrically connected together and separated by an alternating series of non-conductive areas.  A variable impedance device with an end-of-travel return mechanism includes a movable actuator rigidly attached to the wiper and constrained to move between two endpoints. A spring engages the actuator near each end point such that when there are no other forces acting on the actuator the spring pushes the actuator back a predetermined distance from each end point. As the actuator traverses this distance, the integral switch pref. undergoes at least one state change.

Title: Creation of maintenance data base - uses mobile terminal to record maintenance tasks for transfer to computer for automatic development of routine task data
Inventor: WAKABAYASHI MASAHIRO
IPC: G06F17/30
Filed: 1991-11-15
Abstract: To build up a database of routine maintenance for the machines in a spinning or similar plant, each completed maintenance task is entered into a mobile terminal for display and transfer to a computer. The maintenance database for all the equipment is then built up automatically, to forecast work and give work analysis and maintenance statistics. Information masks are stored for condition, status and events with primary instructions in a hierarchical structure. An input mask is for the insertion of codes or symbols and can be called up on a display. When at least one element of information is selected by a keystroke, for condition or status or event, the selected item is shown as maintenance information on an integrated circuit card. If there are no relevant information data from the masks, maintenance information is inserted as a code or symbols for the IC card display. ADVANTAGE - The technique automatically builds up a maintenance database, to show the routine work to be done at any time, using standardised or unified information units.
