Title: Safety device for automobile steering column lock - prevents operation of steering column lock unless gear selection lever is in parking position
Inventor: VEHRKE HEINZ
IPC: F16H59/10
Filed: 1992-02-28
Abstract: The safety device uses a blocking lever (26) and a cooperating operating electromagnet (29), which only allows the gear selection lever (10) for the automatic transmission to be moved out of the parking position (P) when the lock cylinder (15) of the steering column lock (14) is in a pivot position in which the vehicle ignition key cannot be removed. The lock cylinder (15) has a cooperating locking lever (20) for blocking its rotation into the pivot position in which the ignition key can be removed, when the gear selection lever (10) is moved out of the parking position and released via a second electromagnet (22) upon the gear selection lever (10) being returned to the parking position. ADVANTAGE - Prevents locking of steering when vehicle is being driven.

Title: Self-releasing fastener for load to parachute - has both holding members coupled by supporting rope to parachute and rip-cord between parachute and locking mechanism
Inventor: GOERICKE DETLEF DIPL ING
IPC: B64D17/38
Filed: 1992-06-24
Abstract: The holding members (12a,12b) hinge to and from each other on a common spindle (13), having overlapping hook portions (14a,14b). A locking mechanism released by the weight of the load prevents them hinging apart. Each member is coupled by a supporting rope (18a,18b) to the parachute (21), and the mechanism is released by a rip cord (22) between it and the latter, and which is shorter than the supporting ropes. These ropes so engage with the members that under the weight of the load they hold them shut and prevent opening. The members can intersect in a scissor pattern at the spindle and can have actuating arms (17a,17b) with which the supporting ropes engage. USE/ADVANTAGE - Self-releasing fastener for load to parachute remains safely shut under load.

Title: CVD to deliver reaction gas to form film of given compsn. - in which reaction zone is insulated from ambient air and reaction zone is linked to outlet channel
Inventor: KAWATA YOSHINOBU
IPC: H01L21/31
Filed: 1992-12-11
Abstract: In the chemical vapour deposition process, to deliver a reaction gas to form a film of a given composition on a substrate surface, the reaction zone is insulated from the ambient air and the reaction zone is linked to an outlet channel. The substrate is supported in the reaction zone and heated, and the reaction gas is introduced to form a film on the substrate surface through the chemical reaction of the gas. An inert gas in introduced through and injection opening round the reaction gas feed opening, open towards the outlet channel. The reaction and inert gas are evacuated through the outlet channel. The inert gas injection opening is at a surface where the reaction zone joins the outlet channel. The inert gas is fed at a pressure under flow measurement control to pass the inert gas to the injection opening. The inert gas injection opening is a circular hole or is a slit or circular slit extending along the entry to the outlet channel. ADVANTAGE - The system prevents any build-up of components from the reaction gas at the edges of the feed, and reduces the probability of foreign bodies adhering to the treated surface.

Title: Toilet paper holder with damping arrangement
Inventor: DURSUN ALI
IPC: A47K10/32
Filed: 1992-12-17
Abstract: The interchangeable rollers over which the paper runs enables the toilet paper to be continuously dampened, depending on the type and thickness of the paper.By turning the regulator to an "Off" position, dry paper is supplied by pulling it. In the "Off" position, the water container is pulled out, filled and re-inserted, and a suitable roller selected to suit the type and thickness of toilet paper. By turning the regulator to an "On" position, and pulling the paper, the paper slides over the roller and is dampened in the places in contact with the roller.
Patent DE-4302803-A1 (DE)
Title: Method for testing an electric line
Inventor: WINKLER HANS-GEORG
IPC: G01R31/58
Filed: 1993-02-02
Abstract: The method serves to test an electric line, in particular an electric line in a glass pane of an alarm. An alternating current signal is fed into the line to be tested. Then, for the purpose of inductive signal absorption, an electromagnetic sensor is led into the proximity of the line. By means of an evaluation and a display unit connected to the sensor it is then possible to determine whether the alternating current signal is induced in the sensor, as a result of which conclusions on the state of the electric line can be arrived at. The alternating current signal fed into the line to be tested has in its positive and negative voltage range a different signal characteristic, for example a different frequency, so that an evaluation signal which is different in term of its phase angle depending on the direction of flow in the line to be tested is induced in the sensor. The induced signal is processed inside the evaluation and display device in such a way that a change of the phase angle, or else the respective phase angle, is indicated via a visual or acoustic display. Here, a phase shift is insignificant, all that is important is the determination of the phase rotation.

Title: Tank venting system and method and device for testing the functioning performance of a tank venting valve
Inventor: BLUMENSTOCK ANDREAS DIPL ING
IPC: B60K15/035
Filed: 1993-04-20
Abstract: A method for testing the functioning performance of a tank venting valve is indicated, which is situated in a valve line of a tank venting system between the intake pipe of an internal combustion engine and an adsorption filter with ventilation line, and which can be actuated for two control conditions, that is an opening and a closed condition,   a) the tank venting valve being actuated in order to achieve either of the two control conditions; b) the pressure on that side of the tank venting valve, remote from the intake pipe, in the tank venting system being tested and checked to see whether the said pressure exhibits a transient behaviour which cannot occur in the desired control condition; and c) a defective tank venting valve being inferred if the condition tested in stage b) is fulfilled.   By means of this method the functioning performance of a simple tank venting valve can be reliably tested, which consequently needs no special mechanical, capacitive or inductive test arrangement. <IMAGE>

Title: Bag tearing-open device, especially for refuse bags (sacks)
Inventor: SAUERTEIG CLAUS
IPC: B65B69/00
Filed: 1993-07-05
Abstract: The invention relates to a bag tearing-open device which is particularly suitable for splitting refuse bags. This device can be used in a dual recycling system.
