Title: Motor vehicle travel speed regulator - uses control unit and drive pedal for presetting load requirement in conjunction with potentiometer
Inventor: BAUER GERHARD DIPL ING
IPC: B60K31/04
Filed: 1991-02-09
Abstract: An input unit (9) supplies the vehicle desired speed. An electronic regulating unit adjusts the actual speed to this desired speed using an adjusting motor (7) influencing the motor load depending on the speed difference between the vehicle desired speed and the actual speed corresp. to a specified type of regulation. Upon resumption of the regulating operation after an interruption, the adjusting signal supplied from the regulating unit (6) to the adjusting element (7) is regulated up to this time according to the load signal specified by the driver. The regulating modifies the load signal specified by the driver if this load signal oversteps the set adjusting signal available from the regulating unit (6). USE/ADVANTAGE - Type system further developed so that, upon resumption of regulating operation after its interruption, vehicle with acceleration specified by driver, is regulated to original vehicle desired speed.
Patent DE-4104959-A1 (DE)
Inventor: HERM HARTMUT DIPL ING
IPC: F28D7/10
Filed: 1991-02-18
Abstract: The invention relates to a heat exchanger (1) having a primary chamber (2) for a primary medium and a secondary chamber (3) for a secondary medium. The two chambers are separated from one another by a gas-tight, thermally conductive wall (4). It is provided that the secondary chamber (3) is bounded by the wall (4) and by an outer casing sheet (5) spaced from this wall (4). The secondary chamber (3) is subdivided into an inner (3a) and an outer subchamber (3b) by a profiled sheet (6) arranged between the wall (4) and the outer casing sheet (5). The profiled sheet (6) is fastened, e.g., only at its upper end to the upper part of the heat exchanger (1) and hangs freely between the wall (4) and the outer casing sheet (5). This does not hinder its thermal expansions. The profiling of the profiled sheet (6) can hold the wall (4) and the casing sheet (5) at the same distance from one another. The secondary chamber (3) is subdivided into tube-like ducts by the profiled sheet (6). Expensive heating tubes are not required.

Title: Locking arrangement for sloping window - involves bolt arresting pin fitted in window grip rotary axis
Inventor: GRENZENDORF DANIEL
IPC: E05B15/00
Filed: 1991-06-03
Abstract: The inclined window and/or balcony door can be automatically locked by arresting its mechanism, the bolt (14B) executing a rotary movement around its axis (12B) as the result of the force of gravity, adopting a position in which a pin (18B) is arrested by it. This prevents the window grip (20B) being turned. The bolt (14B) is rotatably located at one end so that it maintains its position because of the force of gravity independently of the position of the window and/or balcony door. The flow of force from the window grip (20B) to the bolt (14B) is limited by a theoretical break point. USE/ADVANTAGE - To prevent unauthorised opening of an inclined window and/or balcony door.

Title: Optical laser sensor for measuring very small deflections - has mirrored sensor surface to frequency shift or modulate solid state laser signal coherently, superimposed with reference laser signal
Inventor: MEHNERT AXEL
IPC: G01D5/26
Filed: 1991-08-01

Title: Remotely controlled hinged window - uses single cable for both opening and closing of window
Inventor: PEROTTI FRANCO
IPC: E05F11/04
Filed: 1991-10-23
Abstract: A hinged window (12) is attached to the fixed outer frame (12) by hinges (14) along its lower edge. The window is held closed by means of a catch which holds a spring-loaded lever in the locking position. The window can be opened by remote control by pulling on a knob (27) attached to the end of a cable (26). The cable releases the window catch and allows the spring-loaded lever to open the window. This lever is fitted with pulleys which act on the cable so that the knob (27) moves upwards. Pulling on the knob when the window is open exerts a force on the pulleys which is transmitted to the lever which in turn closes the window. USE/ADVANTAGE - Remotely operated window which used the same cable to open and close it.
