Title: Plug link for an electrical equipment plug having at least one phase-conductor pin (live-conductor pin) and one neutral-conductor pin
Inventor: TALLER MICHAEL
IPC: H01R43/00
Filed: 1988-11-18
Abstract: In the case of a plug link for an electrical equipment plug for the connection of electrical equipment, especially domestic equipment, to a plug socket of an AC mains power supply, the equipment plug being formed essentially by the plug link which, for its part, consists of a dimensionally stable insulating body for accommodating and fixing at least one phase-conductor pin and one neutral-conductor pin, a separating wall (6, 6'), which extends into the region of the ends of the pins, is provided on the insulating body (1, 1'), on the sides of the connecting pins (3, 4; 3', 4') (which are located in the interior of the contour of the equipment plug) of the cable connections between the connecting pins (3, 4; 3', 4') for the phase-conductor pin and the neutral-conductor pin. This reliably ensures that any projecting individual wires or connecting pins which are bent by incorrect handling are insulated from one another. <IMAGE>
Patent DE-3841519-A1 (DE)
Title: Cold trap with rotating magnetic field
Inventor: REIMANN JOERG DR
IPC: C22B9/02
Filed: 1988-12-09
Abstract: In cold traps, contaminated metallic fluids are more satisfactorily cleaned if a further velocity component in the peripheral direction with respect to the cold trap excess is impressed on their throughput rate. This is forcibly accomplished by a rotating magnetic field applied on the outside, so that the molten metal covers a longer distance in the annular gap. The separation of the impurities is enhanced by additional flow obstacles in the annular gap. On the one hand, they enlarge the surface in the annular gap and, on the other hand, they force the formation of secondary flows. This assists the mass transfer and hence the precipitation of the impurity.

Title: Arrangement for indicating that a motor vehicle is braking
Inventor: MARINESCU-PASOI LUCIAN DR
IPC: B60Q1/44
Filed: 1989-03-10
Abstract: An arrangement is described with which the braking of a motor vehicle is indicated in stages, namely either in that a plurality of brake lights of a brake light strip are activated in accordance with the respective deceleration or the intensity of the brake lights is appropriately controlled. For this purpose, the output signal of the speedometer of the motor vehicle is fed to a microcontroller which controls the brake light or the brake light strip appropriately. The proposed system not only provides an improvement in traffic safety by virtue of providing additional information but also the arrangement according to the invention can be realised as an additional safety system independently of the existing brake signal system. It cannot be influenced by mechanical vibrations and consists of cost-effective components. Furthermore, it does not greatly affect the already existing structures of the vehicle.

Patent DE-4022974-A1 (DE)
Inventor: MOSES KLAUS DIPL ING
IPC: G02F1/01
Filed: 1990-07-19
Abstract: The recording medium disclosed comprises a substrate carrying a heat-sensitive film which can be converted into different optical states under the influence of temperature (e.g. opaque and transparent). These states are permanent at normal ambient temperature (e.g. room temperature) and reversible by heating to specific temperatures. The recording medium is designed such that four dots (F) are combined in groups of four to form zones (B), each of the dots (F) having a different primary colour (e.g. red, yellow, blue or black). If the heat-sensitive film over a dot (F) in a zone (B) is converted by appropriate warming to the transparent state, the dot lying under the film becomes visible. This makes it possible to record coloured data, either on a recording medium in the form of a sheet or in the form of a continuous strip from a display device.
