Patent DE-4121003-A1 (DE)
Title: Testing condition of trolley wire lines of electrical tracks - standardising measured max. line current and voltage to simultaneously measured charged-up capacitor voltage differentiation between short-circuit and normal condition of line
Inventor: KUNZE WOLFGANG DIPL ING
IPC: G01R31/58
Filed: 1991-06-21
Abstract: A charged-up capacitor (8) is connected on the stretch of electrified line. The max. line current and the voltage assigned to this current or the integral values of the current and/or the voltage are determined across the line resistance in established time limits. The integral values are standardised to the simultaneously measured capacitor voltage. The condition of the stretch of line is reached, by the comparison of the line resistance (RSt) computed from the current and voltage with a line resistance limiting value (RSt gr) by comparing the integral value with a specified limiting value. ADVANTAGE - Gives unambiguous determination and identification of travel lines of electrified track, including vehicles and auxiliary drives.

Title: Washing machine detergent dispenser - has chambers to divide it for two feeds with second dose delivery when water bath temp. is at optimum level
Inventor: FUMAGALLI SILVANO
IPC: D06F39/02
Filed: 1991-07-23
Abstract: The washing agent and detergent dispenser, in a washing machine together with the water feed, has five chambers for different powders and the like which are arranged so that the washing cycle using only one detergent is executed in two successive time intervals. The second dose of detergent is delivered to the wash, by an operating switch to the program operation, when the water bath temp. has been brought to the required level for max. cleaning effect on the wash. In the dispenser, the first trough-shaped container chamber (2) holds the washing agent for the prewash cycle, while the next two chambers (3,4) hold the required amounts of wash powder. A further chamber (5) has a bleach, and the final chamber carries other washing additives. The chambers (1-6) are formed into a single component, which slides on its mounting in the washing machine, and can carry liquid detergents as well as powders. Channels (8) within each chamber (1-6) extend to the working zone of a jet (9) which rotates at the end of a water feed. The jet (9) is positioned by a rod linkage, operated by a control cam or the like. The cam moves the jet (9), through its segments, to deliver water into the chamber (4) for the second detergent dose after an operating switch has been tripped. ADVANTAGE - The dispenser makes max. use of the behaviour and characteristics of the detergents and other media being used in the washing machine.
Patent DE-4127896-A1 (DE)
Inventor: GERKE DIETER
IPC: H05K1/18
Filed: 1991-08-22
Abstract: Remote disconnecting devices are needed for being able to determine at the point of interconnection of the telephone network of one operator with the network of another operator in which part of the coupled networks a fault has occurred, that is to say to separate the networks from one another with respect to direct voltage for measuring purposes. 
<??>Remote disconnecting devices based on TRIACS and MOS-FETS are known, where a uniform switching threshold is used. If controlled silicon rectifiers are used as electronic switches, the switches are connected to one another by a switching element in order to be able to transmit dialling pulses from the telephone to the exchange and to use switches with insensitive control terminals. 
<??>According to the invention, the use of self-inhibiting MOS-FETs of the enrichment type provides for a high turn-on threshold and a low turn-off threshold so that the usual measuring method of dropping the voltage can be used. It is also possible to make the turn-on threshold dependent on the polarity of the voltage.

Inventor: ANDREI-ALEXANDRU MARCEL
IPC: B60S1/08
Filed: 1992-01-30
Abstract: The windscreen-wiper motor described has a limit switch whose method of operation is based on the fact that a contact spring (2, 17) which is connected to the motor drive is deflected by a rotating disc (1, 14) in such a way that the spring reverses the electrical contacts of the motor (3, 4, 20, 21).

Patent DE-4316043-A1 (DE)
Title: Optoelectronic force and pressure measuring system
Inventor: ETTNER KARL-HERMANN
IPC: G01L9/00
Filed: 1993-05-13
Abstract: The optoelectronic force and pressure measuring system having a deformation element constructed as a double parallel spring articulation system, on which there is arranged a transmitting and receiving unit, ensures the picking-up of two-dimensionally acting static and dynamic forces via force coupling elements and their conversion into two-dimensional displacements of an area of light projected by the transmitting unit. In this arrangement, the receiving unit is arranged and fixed in the parallel spring articulation system such that the light entry surfaces, assigned to at least four receiving diodes, are arranged on diagonals of a square, these light entry surfaces being identical with the displacement directions in the X- and Y-direction predetermined by means of the constructional configuration of the parallel spring articulation system, and the point of intersection of the diagonals coinciding with the optical axis of the transmitting unit. By means of the linear change of the light intensity on the receiving diodes, which is produced by the displacement of the projected light area, and electronic difference signals resulting therefrom, the direction and magnitude of a force which is acting can be measured exactly. In addition, there can be arranged in the receiving unit reference diodes which are used for the detection and compensation of the effect of undesired influencing factors such as temperature changes and voltage changes. In a similar fashion, by means of correspondingly configured housing versions, it is possible to measure pressures in closed systems by means of interposed diaphragms.
