Patent DE-3536148-C1 (DE)
Title: Window with blind and casement frames - has ventilation system which preserves integrity of sound insulation
Inventor: STIEBICH FRIEDRICH
IPC: E06B7/10
Filed: 1985-10-10
Granted: 1987-05-14
Abstract: The window consists of blind frame and casement frames forming chambers when closed so that the room/side chamber is sealed to the casement and frame as compared with the weather/side chamber which leaves an air gap right round and has side holes to lead the air up to outlets in the top cross rail of the casement. One air hole should be in each of the vertical inside flanges of the blind frame and lead into the sealed room/side chamber. There should be a transfer hole on the contact rim of the top casement rail below the sealing strip leading from the sealed chamber into the cross rail. The transfer hole is allocated two offset air outlets in the cross rail. USE/ADVANTAGE - Building construction window fittings. Ventilation assured without detracting from soundproofing, with easy air channel cleaning access. Air at no point makes direct contact with the glazing.

Title: Method in a system for the operation of industrial trucks and system for implementation of this method
Inventor: HELLMANN GUENTER DIPL-ING
IPC: B60T7/18
Filed: 1985-11-05
Granted: 1987-07-30
Abstract: In a system for the operation of industrial trucks which have at least one drive wheel in contact with the ground, the vehicles are operated without a driver. For reliable stopping of the vehicle, the ground contact of the at least one drive wheel is cancelled by profiling areas of the driveway and, instead, established with the vehicle body or a support arrangement fitted to this. The vehicle is thereby automatically braked due to the friction forces which arise. The system may have control wires laid in the ground for guiding industrial trucks, whilst other guides may be provided at the vehicle's stopping point. In the system, the ground (1) has a design, with profiled sections (16) arranged in the direction of travel of the at least one drive wheel (10), said profiled sections being of such a depth/height perpendicular to the driveway that contact between the at least one drive wheel (10) and the ground is cancelled in the area of the profiled section and part of the vehicle comes in contact with a braking surface. In this arrangement, the elevated profiled section may be designed as a depression or ramp. <IMAGE>

IPC: H02H9/00
Filed: 1990-12-17
Granted: 1992-02-27
Abstract: The current limiting circuit for use with a plug connector (St) supplying a capacitive (C) load (V) makes use of a resistor (R17) connected between the supply (S) and load (V). A semiconductor switch (S1) e.g. a FET is controlled by the voltage drop across resistor (R17). When in turn is compared with reference voltage in comparator (K1). OR-gate (od) holdes the switch (S1) open via a signal (A) DNTD the voltage drop across the resistor (R17) falls below a limiting value. Temperature responsive current sink (Q) absorbs capacitive surge until finally shunted by the FET (S1) and resistor (R1). USE/ADVANTAGE - In situations where capacitive load generates surges at instant of connection. Limits current surges in a reliable manner and dissipates their effect in as short a time is consistent when plug contact capability. Discriminates between capacitive surge and load short circuit to protect circuit components.

Title: Method and device for the stationary determination of leaks in a fuel tank venting system
Inventor: KOLB HARTMUT DIPL ING
IPC: B60K15/035
Filed: 1994-01-15
Granted: 1995-04-27
Abstract: The invention relates to a method and a device for the stationary determination of leaks in a fuel tank venting system arranged in a vehicle with internal combustion engine. It is proposed to produce a prescribed pressure in the fuel tank venting system using a pump and to detect the times which are required to build up the pressure and subsequently reduce it. By comparing the quotient of the times for the building up of the pressure and the reduction of the pressure with a prescribed threshold value, a leak can be detected. In order to localise the leak, it is also proposed to use coloured gas for building up the pressure. The device for carrying out the method consists of a test unit which has a pump, a pressure sensor, a clock and a control component and which is connected to the fuel tank filler stub via a test line having a sealing collar. In addition, it is proposed to locate the mouth of the venting line of the fuel tank venting system in the area of the fuel tank filler stub so that the mouth of the venting line is also covered by the sealing collar of the test line.
