Title: Weighing of load being lifted by hydraulic cylinder
Inventor: MULTER HELMUT
IPC: G01G5/04
Filed: 1994-02-17
Abstract: The load (28) is supported by a plate (26) on the end of the vertical piston rod (24) of the double-acting cylinder (20) which has pressure gauges (32, 33) on its feed and drain tubes (30, 31). For the weighing operation, the piston (22) is immobilised and the rate of damping of the consequent oscillation is observed. The changes of pressure on both sides of the piston are sampled during one or more cycles and averaged. The wt. is deduced from the difference between the averages with allowance for the piston areas on which the pressures are exerted.

Patent DE-4410506-A1 (DE)
Title: Control system for opening or closing an opening/closing element
Inventor: TAKABE YASUHIRO
IPC: F16P3/12
Filed: 1994-03-25
Abstract: The invention relates to a control system for opening or closing an opening/closing element when a foreign body is clamped in by the opening/closing element. The circumstance of the opening/closing element clamping in the foreign body is determined on the basis of a drive state of a motor for driving the opening/closing element, e.g. a window with an electric pane-lifter. Thus the case of e.g. a foreign body being clamped in is established when a drive acceleration or a drive speed is lower than a respectively predetermined threshold value X or Y. Each of the threshold values X and Y is adjusted fundamentally on the basis of the preceding drive acceleration and speed of the opening/closing element. The threshold values X and Y are amended on the basis of a condition which exerts an influence on the drive state of the motor, e.g. on the basis of a drive voltage or a resistance in relation to a sliding movement of the opening/closing element.

Title: Vehicle bench seat arrangement
Inventor: KOHL HORST DIPL ING
IPC: B60N2/75
Filed: 1994-05-27
Abstract: The bench seat arrangement in a vehicle has the back support (3) fitted with an armrest (6) which folds down. Only during or at the end of the fold out process does the adjacent support (7) move outwards.  The outwards movement of the support is achieved inherently due to the coupling and action of the armrest being dropped. The support automatically returns to the original position as the armrest is returned to its out of use position.

Patent DE-4435153-A1 (DE)
Inventor: SCHMIDT GUENTHER DIPL ING DR
IPC: B60T8/48
Filed: 1994-09-30
Abstract: The invention starts from a vehicle immobilisation system (34) in which a reversing valve (20, 20') for each braking circuit maintains a pressure accumulated in the wheel brake cylinders (16, 16') when a brake pedal (14) is actuated. Its disadvantage is that the pressure may fall because of small leaks or cooling down of the braking fluid, so that the vehicle may again be moved. To avoid this disadvantage, when an illicit use of the vehicle is recognised, pressure is increased in the wheel brake cylinder (16, 16') by means of a hydropump (30, 30') for each braking circuit.

Filed: 1994-10-07
Abstract: The owner wears a transponder (2) on his wrist which when brought into proximity of a pick up coil (3) near the vehicle door lock releases the central locking system without need of a door key. The same transponder is brought near to a second coil (10) which controls the release of the ignition block and allows the ignition to be turned on via a keyless switch (11). The transponder emits a coded string of signals, which can be a duplex communication between the transponder and the processor control unit (3) to which the coils are connected. The ignition is inhibited unless the central locking system is first released by the transponder. The transponder can be incorporated in a wrist watch, ring or other items of jewellery etc.

Abstract: The system contains trackside communications devices (LL1,LL2,B1,2,S1-S4) associated with each direction along a track and via which the vehicle can receive data from fixed control devices or exchange data with them. The data are used for detection of directions of travel and positions from known locations of fixed devices (B1,B2), loop ends (SB) and crossing points (K). Additional position detection is also performed using the positions of devices associated with the opposite direction of travel (V,R). The results are passed to the vehicle and/or stored in the fixed controllers and made available to the vehicle when a change of direction occurs.

Title: Safeguard for laser operated distance measurer in motor vehicle
Inventor: WAFFLER ANDREAS
IPC: G01S17/04
Filed: 1994-12-15
Abstract: The safeguard includes a conventional laser distance measurer (1). The measurer has a transmitter (2) and a receiver (3), which are usually fitted behind the inside mirror on the front windscreen (4) in a vehicle. To ensure that the driver's hands or eyes are not exposed to laser beams, a proximity sensor is fitted close by. The proximity sensor has a source for ultrasonic wave transmission (5), which scans (6,7) the front part of the vehicle. If any objects come into the sensor range, a signal is transmitted to the laser transmitter, which is then reduced by up to 90% to ensure safety for the components.

Title: Preparation process of transparent coating powders made with copolyamides
Inventor: FELDMANN R
IPC: C08K3/36
Filed: 1979-03-17
Abstract: Improved process for preparing transparent coating powders from copolyamides ground into powder at a low temperature. These copolyamides contain at least 30% by weight of lauric lactam, as well as at least 10% by weight of aliphatic dicarboxylic acid groups containing from 4 to 12 carbon atoms and equivalent remains of aliphatic diamines with lateral chains or cyclic diamines containing from 4 to 12 carbon atoms; these copolyamides are obtained by hydrolytic lactamic polymerization. With a simplified method transparent powders are obtained which are particularly appropriate for coating metal pieces with a transparent coat: for this purpose, from 0.01 to less than 0.15% by weight of silicic acid in the form of powder, is added to the copolyamides before or after the grinding; this pulverulent silicic acid is obtained by grinding and should have a surface of 380 +- 30 m2/gr (measured according to the BET method), and the primary particles should have an average diameter of 7 nm; the silicic acid is obtained by precipitation, having already a surface of 190 +- 20 m2/gr and the average size of the primary particles being 18 nm. After grinding, the powder is dimensioned to the desired size of particles.
Patent WO-8302699-A1 (WO)
Title: Emergency transmitter and operating method thereof
Inventor: HANSEN HOLGER
IPC: H04B1/034
Filed: 1983-01-19
Abstract: The transmitter is provided with separate means for the transmission of a first frequency and a second frequency. It is contained within a floatable housing. The transmitter is connected through a switch to a battery. The transmission means are comprised of a common quartz oscillator connected with frequency multipliers which are connected to drive stages and to high frequency final stages. The latter are connected to a transmission antenna which extends from the housing, as well as to a signal generator for modulating the transmitted frequencies. A problem raises when rescuing at sea as to the size and weight of the apparatus in particular when it is permanently carried by a person. A decrease of these parameters is not possible beyond a certain limit due to the capacity of the battery and the transmission output. To solve that problem without decreasing the range and duration of transmission while reducing almost by half the size of the battery as well as the power that it should deliver, a clocked control device (for example 36) is incorporated to the first (11) and to the second (13) transmission means which alternately sets in operation both means (11, 13). Thus, the operation requirements of the battery are reduced to those necessary for a single transmission device.
