Patent DE-4010872-A1 (DE)
Title: Embossing of leather for steering wheel covers - by applying thermoplastic layer locally on underside to stabilise pattern when leather is stitched under tension
Inventor: SCHAEFER ERWIN
IPC: B44C1/24
Filed: 1990-04-04
Abstract: A flexible, slightly compressible material, particularly leather, is permanently embossed with a die. The underside of the embossed region is covered and filled by a hardenable synthetic material.  The synthetic material can be a thermoplastic and embossing as well as application of the synthetic material can be carried out under heat. When used to cover vehicle steering wheels the warmed material is stretched round the wheel and stitched along the edge. The leather covering (2) of a steering wheel is embossed under heat so that in the embossed regions (3,4) the grain virtually disappears to give a smooth surface and locally (6,7) the leather is thinned. To stabilise the embossing and avoid it being stretched out when the leather covering is stitched under tension on to the steering wheel a thermoplastic material (8) is applied by a counter-die on the underside. The underlying polyurethane foam is cut away to accommodate the thickness of the thermoplastic backing so that the outer surface of the leather remains level round the embossing. USE/ADVANTAGE - The process is used to give permanently embossed letters on vehicle steering wheels.

Patent DE-4024607-A1 (DE)
Inventor: THIES MATTHIAS
IPC: A47B43/00
Filed: 1990-08-02
Abstract: The invention relates to a multiple-use package, which also serves as a transport container, for replacing disposable packages, such as shoe boxes. Furthermore, the container according to the invention is also intended to be used directly for display in the retail trade and to replace there the previously used, primarily stationary shelving systems. In this case, not only is packaging material saved, but also personnel expenditure since time-consuming unpacking, etc. for the display is not required. This is achieved in that the container essentially has the form of a collapsible shelf unit, whose intermediate shelves can assume a sufficient inclination to serve at the same time for display, and in which the articles to be accommodated can be fixed directly to the intermediate shelves without damage for transportation. Individual containers can readily be combined to form larger units and can be collapsed to a small volume in the empty state and transported back for refilling. <IMAGE>

Title: Heater leak indication device - automatically cuts out feed pump when leak detected by differential pressure switch
Inventor: HORN HUGO
IPC: G01M3/28
Filed: 1990-10-04
Abstract: The leak indication device has a differential pressure switch connected between a supply pump and load if used with a press. line. The switch is active when the pump and load are idle and interrupts the voltage supply to the pump if the press. in the line drops because of a leak. The pump is automatically deactivated and an alarm signalled. If used with a suction line the differential switch is connected in series with the pump and interrupts the voltage to the pump if a leak is detected whilst the pump is idle. USE/ADVANTAGE - For use with press. or suction systems of discontinuous operation, e.g. for heating system burner pumps, the arrangement achieves automatic pump cut-out when leaks occur.

Title: Traction control for motor vehicle - computes grip coefft. to set threshold slip valve w.r.t. road conditions
Inventor: TSUYAMA TOSHIAKI
IPC: B60T8/172
Filed: 1991-06-21
Abstract: Each wheel is fitted with a wheel-speed sensor and the slip of the drive wheels is computed by comparing their speed with that of the driven wheels. The grip coefft. is computed for use in setting the threshold slip valve. This coefft. is constantly updated for optimum traction control. When the vehicle is started the slip is controlled by regulating the motor torque and the initial grip coefft. is calculated directly via the wheel-speed dynamics and the engine torque. Subsequent control is via. slip measurements over preset time periods. The wheel spin is controlled by a combination of engine torque reduction and wheel braking. ADVANTAGE - Improved traction cotnrol, operates over range of road surfaces.
Patent DE-4124633-A1 (DE)
Inventor: KREYER RUDOLF
IPC: A01K31/16
Filed: 1991-07-25
Abstract: To reduce the technical process complexity in an egg collecting installation with an egg counter, it is proposed to form the metering devices (4) for isolating and transmitting the eggs (11) produced from the collector belts (2) which convey the eggs (11) from the laying batteries to paternoster-like collector belt (5) as shafts rotatable about their longitudinal axis (18) having egg recesses (17) open in the radial direction and to adjust the revolution speed of the metering device (4) to the rate of conveyance of the paternoster-like collector belt (5) in such a way that certain egg-trays (7) of which the individual members (6) of the collector belt (5) consist are allocated to each collector belt (2). The collector belt (5) and the metering devices (4) are actuated by the same drive. If the egg trays (7) are suitably marked, it is possible with the aid of only one contactless proximity switch (15) for counting and identifying the egg trays (7) of the collector belt (5) and a corresponding counting device (12) for counting the eggs (11) not only to find the total number of eggs (11) laid but also to allocate the eggs to the individual collector belts (2) or rows of cages. The egg collecting installation (1) is thus less liable to breakdowns as a whole and operates with greater counting accuracy. The counter results found may be graphically displayed via a computer or fed into a central EDP installation.
