Title: Leak testing method, esp. for hydraulic systems - involves filling test vol. and test device partial vol. with test liquid, changing test vol. and measuring resulting press. step
Inventor: NOLTE ALBERT
IPC: G01M3/32
Filed: 1992-11-16
Abstract: A test vol. contg. at least the vol. of the hollow chamber to be tested and the partial vol. of the leak testing device relevant to testing are filled with a test liquid and with air at a defined press., and the test vol. is closed. The air vol. component in the test vol. is determined by changing the test vol. and measuring the resulting press. step. As required, the air vol. component is corrected until a defined press. step is produced. The press. drop in the test vol. is measured and evaluated. USE/ADVANTAGE - Can be used with low test press., is insensitive to seal tolerances and enables reliable, rapid testing without visual or vol. monitoring of test medium.

Title: Safety unlocking device for overhead door
Inventor: HOERMANN MICHAEL DIPL ING
IPC: E05F15/603
Filed: 1993-04-06
Abstract: The safety device is for heavy doors movable into an overhead position and typically driven by a geared electric motor and with counterbalancing torsion springs, it being possible to uncouple the door from the drive mechanism on power failure etc. A detector (1) for the door position releases an unlocking component (9) uncoupling the drive mechanism only with the door shut. The detector and component can be mechanically coupled, typically via a stretch-simulator (11) formed by a non-slip spindle driven by the mechanism and engaging in a non-rotating tapped slide. The latter in turn actuates the component with the door in the shut position.

Title: Length transmitting device for determining the position of a scanning device on a cable, and a method for determining position in such a way
Inventor: PROESDORF DETLEF DIPL ING
IPC: G01B7/00
Filed: 1993-05-04
Abstract: In the case of a length transmitting device consisting of a cable and a scanning device which can be displaced relative to one another, the cable has non-magnetic regions and magnetic longitudinal sections, respectively of constant length, which serve as marks in an alternating fashion in the longitudinal direction. Each magnetic longitudinal section comprises segments which, in accordance with their respective magnetisation sequence, form a magnetic bit pattern and consequently an individual binary identifier which specifies its sequence with respect to the other longitudinal sections. The marks which border a longitudinal section stipulate the start of a word and end of a word of the respective identifier. For the purpose of simultaneous readout of a bit pattern, there is provided on the scanning device a chain of sensor elements whose number and spacing from one another depends on the word length of the binary identifier. The reference point is provided by a sensor element which bears appropriate information on the adjoining mark.

Patent DE-4334671-A1 (DE)
Title: Restraining system
Inventor: FAYE IAN
IPC: B60R21/01
Filed: 1993-10-12
Abstract: A restraining system is described. Initiation of the restraining device is made even quicker if it is ascertained that a front wheel is decelerating too quickly. This results in improvement of crash sensing in the case of certain types of crash (for example collisions into soft objects). Collisions of this type, which are also called "problem crashes", often cause problems for conventional central crash sensing systems which are unable to reach a decision on whether to initiate the restraining system in good time. <IMAGE>
Patent DE-4405832-A1 (DE)
Inventor: ZADGORSKA ZDRAVKA
IPC: G01N21/73
Filed: 1994-02-23
Abstract: The invention concerns a sample-aspiration system with a sample holder connected to the burner tube of an ICP-AES spectrometer as well as a gas-supply line. The sample holder (2), which can be heated, is connected to the bottom of the burner tube (1) by a cylindrical or conical channel (4). The gas-supply line (8) is also connected to the bottom end of the burner tube. The gas inlet (5) into the burner tube (1) surrounds the sample channel (4) so that the gas flow from the gas inlet envelops the zone round the centreline of the burner tube above the sample channel. The invention calls for a first component (3) which surrounds the top of the crucible-shaped sample holder concentrically to form a seal, the upper end of this component being cylindrical in shape. This compoenent has an aperture (4) which connects the sample holder to the burner tube (1). A second component (6) ensures a gastight connection between the first component and the burner tube (1). The bottom end of the burner tube has a downwards-reducing taper which fits tightly into an upwards-opening cone in the second component (6) which is made of metal and is cooled. The first component (3) projects into the burner tube in such a way that it forms, between itself and the inside wall of the burner tube (1), the gas inlet (5) surrounding the sample channel. The sample-aspiration system proposed is compact in design and can be manufactured using inexpensive materials. In addition, it is easy to heat the crucible-shaped sample holder.

IPC: E05F15/08
Filed: 1994-09-02
Abstract: The invention relates to a window with a window sash which can be displaced in the vertical direction in the open position within a window frame, the window sash being connected to cable-like pulling elements which are connected, via deflection elements on the window frame, to a pulling device which pulls the cable-like pulling elements with a force directed counter to the force of gravity of the displaceable window sash. Said window is intended to be improved in that, along with the lowest possible space requirement, it is to produce little noise, to be capable of easy mounting and to be opened in a simple manner without complex counterweights. This is achieved in that the pulling device is designed as a piston/cylinder unit (10) which is under pressure, one end (13) of the piston/cylinder unit (10) being articulated on the outside of the window frame (2) and the other end (16) being connected to the cable-like pulling elements (5, 6). <IMAGE>
