IPC: G01N27/417
Filed: 1991-03-22
Abstract: The invention relates to a device for the continuous monitoring of the concentration of at least one gaseous component of gas mixtures. In prior art devices, their complicated construction, high power consumption, great bulk, non-uniform temperature distribution owing to their great mass with consequent measurement inaccuracy and inertia are disadvantageous. The prior art disadvantages are overcome by the device of the invention in that a support takes the form of a small plate on one side of which there are at least two electrodes arranged at a mutual distance as thin films, on one side of the ceramic plate there is a temperature sensor at a distance from the electrodes and on the other side of the plate there is an electric resistive layer for heating.

Title: Applying contact element to end of insulated conductor during automated cabling - measuring dia of conductor end after automatic insulation removal as integral part of production process
Inventor: GRIEMSMANN BERND DIPL ING
IPC: H01R43/05
Filed: 1991-05-15
Abstract: The method of applying a contact element to the end of a conductor with plastic insulation involves automatically removing insulation from the conductor's end before changing the position of the end and applying the contact element. During the removal of the insulation or during the repositioning of the stripped end, the dia. of the conductor is measured using a light sensor which produces a measurement signal characterising the stripping process. This signal is electronically processed to form a control signal for the automated step sequence for further processing of the conductor end. USE/ADVANTAGE - For use in automated cable harness production for vehicle applications. Method integrates monitoring of cable stripping process into manufacturing procedures.

Title: Magnetic measurement system for shaft rotary angle - contains magnetically conducting rotor, two fixed, relatively offset field plate sensor elements producing sine and cosine signals and evaluation unit forming quotient
Inventor: VOGT GUENTHER DR
IPC: G01D1/16
Filed: 1991-09-06
Abstract: A magnetic measurement system for rotation angle measurement contains a weakly magnetically conducting rotor (11) rigidly attached to the measurement shaft and two fixed, relatively offset sensor elements (13,14). As the shaft rotates one sensor produces a period of an approximately sinusoidal signal and other of a cosinusoidal signal per rotation. An evaluation unit derives the absolute rotation angle from the quotient of the two signals. The rotor has a coaxial channelled recess (12) which spirals at least over a full 360 deg. Each sensor element is a field plate differential sensor, both of whose field plates (15,16) are arranged opposite the recess with a small air gap. USE/ADVANTAGE - At least technically equivalent to resolver at considerably lower cost. Contactless working, robust and not requiring servicing.

Title: Hydraulic supply for active suspension - has supply regulated w.r.t. vehicle speed for constant flow rate
Inventor: KAWABATA KAZUNOBU
IPC: B60R16/08
Filed: 1991-09-12
Abstract: The active suspension has sensors for vehicle speed, lateral forces, vertical displacement etc. to determine the flowrate required for the suspension elements. Below a set speed the system supplies a lower rate of flow. To ensure stability the flowrate remains at the higher rate for a set time interval after the speed has dropped below the threshold level. This ensures no sudden change in flowrate. The pumping system has two pumps driven synchronously and with one pump with a larger output. The outputs from the pumps are selectively switched off to control the flowrate. ADVANTAGE - Reduced fuel consumption, no sudden change in control.

IPC: G11B27/00
Filed: 1992-01-16
Abstract: The invention concerns a system which enables the titles of recordings to be selected from storage media containing a number of titles and held in a magazine, in particular the titles of CDs housed in a number of CD boxes.

Title: Spiked winter tyre which generates min. wear on road - has tread divided into outer cap with holes holding loose spikes and inner base with low hysteresis only at temp. above freezing point
Inventor: RODEWALD HELMUT DIPL ING
IPC: B60C11/00
Filed: 1992-03-19
Abstract: Winter tyres have spikes held in radial holes in the treads. The tread in each case is divided into a lower base and an outer cap; the spikes rest loosely in holes in the cap; they are only stopped from moving radially inwards by a supporting element by the base. The base is made of a material which presents a greater resistance to penetration by the spikes at low temps. than at higher temps.; by this means and regardless of temp. the spikes are moved outwards by centrifugal force and touch the road surface when they pass through the outer surface of the tyre; if the temp. is above the limit concerned, however, they only stand out with a reduced prssure. The base part is pref. a rubber contg. styrene-butadiene. ADVANTAGE - Whilst the tyre retains the usual advatnages of spikes for winter conditions it minimises the wear on the road surfaces.
Patent DE-4211495-A1 (DE)
Title: Overload protection for capacitor split- phase motor - has induced voltage in unexcited winding compared with DC reference and microprocessor to initiate relay if threshold exceeded
Inventor: LIPPKAU UWE
IPC: H02H7/085
Filed: 1992-04-06
Abstract: The capacitor motor (start-and-run-type) has two windings, one for each direction of rotation, and a single phase voltage supply for each. A potential divider chain from the supply terminal for each winding to earth has a zener diode and suppressor capacitor across the earth-side resistor of each. The voltage across one earth-side resistor is proportional to the stator voltage of the active winding and the voltage across the other earth side resistor is proportional to the induced voltage in the respective unexcited winding, and therefore motor torque. These voltages are compared with reference DC voltages obtained by rectification from the mains and a microprocessor initiates a transistorised relay if motor torque exceeds a threshold. ADVANTAGE - Simple, inexpensive and space-saving method for motor protection against overload.

Filed: 1992-04-21
Abstract: The upper part (11) has a hollow ram (27) projecting into the spring volume (25) and having in its end and/or sleeve face at the end at least one opening (29). The end of the ram projects into a chamber (23) filled with hydraulic medium (24) and set in the spring volume (25) of the lower part (21,22). The cross-section of the hollow ram is less than the cross- section of the chamber containing the hydraulic fluid. A membrane is set between the ram and piston wall (21) above the hydraulic medium to keep out dirt and fluid. ADVANTAGE/USE - The desired level of the component being supported is maintained even with changing loads through the movement of the ram in the hydraulic medium. Long service life by avoiding friction seals.
