Title: Mechanical code protection for vehicle central locking system - has key with coded pattern on shank to preset array of security switches
Inventor: TEHRANI AKRAM MEMAR
IPC: E05B49/00
Filed: 1992-06-25
Abstract: The central locking system uses a special key with a pattern on the shank. This operates on an array of spring loaded switches, to open and close certain connections in a logic circuit. This inactivates the coding and operates the various locking servo motors in the correct direction. The mechanical coding is simple and has a large number of variations. The array of switches operate on a transistorised security circuit with IC logic. The system sets the alarm and is activated by operating any other switches e.g. opening the doors. ADVANTAGE - Simple security system, difficult to bypass.

Title: Worm gearing
IPC: F16H35/10
Filed: 1993-04-06
Abstract: The invention relates to a worm gearing with a safety coupling (5-13) to limit the transmissible torque in one direction of rotation (forward motion) of the worm wheel (16), the safety coupling (5-13) permitting the transmission of a higher torque in the opposite direction of rotation (reverse motion) of the worm wheel (16). To improve the worm gearing, the invention proposes the following features:   a) The safety coupling (5-13) is seated on the shaft (worm shaft 2) which carries the worm (3) and transmits the torque introduced into the worm shaft (2) to the worm (3), which is arranged in freely rotatable and axially displaceable fashion on the worm shaft (2); b) the safety coupling (5-13) comprises a freely rotatable friction disc (5) which is connected rotationally to the worm (3), is freely rotatable relative to the worm shaft (2) and is arranged between two driver discs (6, 7) which can be clamped against one another by a spring force and are connected rotationally to the worm shaft (2); c) in forward motion, the worm (3) is supported by one end face directly or indirectly against an abutment (15) and, in reverse motion, is supported by its opposite end face against a component of the safety coupling (5-13) which increases the spring force.   <IMAGE>

Title: Method and device for the non-contact measurement of torques on shafts
Inventor: ROMBACH PIRMIN DIPL ING
IPC: G01L3/10
Filed: 1993-04-26
Abstract: Prior art, problem A non-contact torque sensor is intended to be small and not to enclose the shaft. Known measuring devices comprise at least one magnetic circuit which is closed via a ferromagnetic layer on the shaft. The torque, which effects an alteration of the relative permeability of the layer, is measured by means of an inductance or of a flux density. Here, a special problem is represented by the fluctuation of the air-gap width between shaft and yoke, which makes impossible an exact measurement of the torque. Solution, invention The problem is solved in that the stray field beside the yoke is measured using at least one additional sensor element. In the case of a suitable geometry, the measured values of core field and stray field can be mutually balanced in a simple way and the torque can be determined. If at least two field coils are used, the sensitivity of the flux density sensor elements can then be calibrated during operation by means of the cyclic excitation of the coils in the same and in opposite directions, and the accuracy of the measuring arrangement can be increased.

Title: Locking-bar securing means
Inventor: FRANZ CARL
IPC: B60P7/15
Filed: 1993-10-18
Abstract: The invention relates to a freight securing means for the freight areas of lorries using vertical locking bars which are attached between the floor of the freight area and its roof and as a result of which secure the freight directly adjoining the locking bar against slipping, principally in the longitudinal direction of the vehicle. The object of the present invention is to develop the known locking-bar securing means in such a way that when there is an equal or greater supporting force in relation to the freight, the said locking-bar securing means manages with even a low degree of rigidity of the roof structure and functions independently of the presence and the direction in which a profile floor is laid. For this purpose, the locking-bar foot has at least one downwardly pointing projection which engages in the surface of the floor of the vehicle in a positively locking manner and when the locking bar is attached between the floor and a perforated rail the pin projects into a hole in the perforated rail, the locking bar exerting no, or only slight pressure upwards against the locking bar.

Title: Control of gas-fired space heating system
Inventor: STAPENSEA JAN-AEDE DIPL ING
IPC: F24D19/10
Filed: 1994-06-08
Abstract: A procedure for controlling a space-heating plant with a gas boiler and a circulating pump has the pump output controlled according to the temperature, but only when the heating demand is low; when the demand is high, the pump output is 100% and independent of temperature. The temperature-dependent regime exists when the outside temperature is above - 5 degrees C.  The full output applies for temperatures below this. Further pump control uses a defined characteristic of boiler mean temperature versus outside temperature. The output of the pump is set at 100% up to a certain boiler temperature, and above this, is controlled according to this characteristic.
