Title: Arrangement for controlling a star/delta contactor combination
Inventor: BAERNKLAU KARL-HANS DIPL ING
IPC: H02P1/32
Filed: 1987-03-20
Abstract: The invention relates to an arrangement for controlling a star/delta contactor combination having a mains contactor, a delta contactor and a star contactor as well as a control timing relay. The mains contactor and delta contactor are jointly connected to the mains voltage. The control coil of the mains contactor is connected via a self-latching contact and a normally-open contact (which is connected in parallel therewith) of the star contactor to the control voltage, and the control coils of the star contactor and delta contactor are likewise connected via mutual locking contacts and a timing contact of the control timing relay to the control voltage. The parallel circuit formed by the self-latching contact of the mains contactor and the normally-open contact of the control contactor is located in front of the timing contact of the control timing relay for the delta contactor. This prevents the delta contactor remaining switched on in the event of voltage failures, so that the motor winding is connected to voltage on one side. <IMAGE>

Title: Safety device with a flexible electrical contact strip for electrical window lifters of motor vehicles and other automatically actuated closing devices for preventing serious accidents as a result of the risk of jamming and pinching during the closing operation
Inventor: SORGATZ WOLFGANG
IPC: B60J10/00
Filed: 1987-07-21
Abstract: The invention relates to a safety device for electrical window lifters of motor vehicles and other automatically actuated closing devices of windows and doors for preventing serious accidents as a result of the risk of jamming and pinching during the closing operation. The invention is characterised in that a flexible electrical contact strip which can be produced very cheaply and has wires inserted into soft rubber and which can serve at the same time as a seal is used. If the contact strip is dented at any point, a relay is cut in and reverses the closing operation. The jamming or pinching of persons or objects is thereby reliably prevented. The same electrical contact strip designed as a seal can also be used as a contact-maker for alarm or other safety devices. A further claim of the invention relates to the use of a short-time retentivity relay for the abovementioned device, in which the relay release time can be influenced or selected by the use of a suitable short-time retentivity material and by the choice of the exciting current.

Patent DE-3823334-A1 (DE)
Title: Reel, especially for wire or cable
Inventor: KREUZNACHT JULIUS
IPC: B65H75/14
Filed: 1988-07-09
Abstract: Known reels consist of plastic in the case of low requirements and solidly, in one piece, of aluminium in the case of higher requirements. These aluminium reels are heavy and expensive and can suddenly break under pronounced load. The new reel is to be light, stable, resistant to breaking and cost-effective. The new reel possesses a relatively thin-walled casing (2) with a conventional outer shape and two end hub rings (3, 4) which are connected to one another via a spacer tube (7), concentric with the casing, and to the casing (2) via centring rings (5, 6). The new reel is therefore lighter and, at the same time, more stable and more resistant to breaking, especially when sheet steel is used as a material. The new reel is therefore also appreciably more cost-effective. The reel is especially suitable for a rapid mechanical winding and unwinding of wires or cables and for the transport of these. <IMAGE>
Patent DE-3825007-A1 (DE)
Inventor: VITE LUTZ DR
IPC: C09D11/36
Filed: 1988-07-22
Abstract: An ink for ink-jet printers is proposed which, besides an organic solvent, contains at least one highly pure colorant and, where appropriate, further auxiliary materials and other organic additives to obtain a certain electrical conductivity which generate ions on being dissolved in at least one solvent. Good electrical conductivities are obtained with quaternary ammonium compounds, e.g. tetra-alkyl ammonium hydroxide or tetra-aryl ammonium hydroxide or other stable organic salts in the ink solution as additives for the ink. Here, the anions are so selected that the ink causes no corrosion in parts of the printer or parts to be printed which contain metals. The invention substantially extends the choice of solvents and colorants usable for inks and guarantees electrical conductivity even with highly purified raw materials and ink components.
