Title: Method and device for optimizing the programme flow in dishwashers and washing machines with softening equipment, in particular for the household
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: A47L15/00
Filed: 1988-12-01
Abstract: In the case of water-carrying household appliances with softening equipment, the soft-water consumption and associated salt consumption is to be restricted to a minimum for the purpose of reducing waste-water contamination. In the case of known appliances, the salt-containing, regenerated softening resinous compounds are rinsed clean before each programme sequence and this hard water is pumped immediately into the drainage system. With the aid of the method according to the invention, all of the washing programmes selectable by the user are designed such that soft water is available only from the most important programme step onwards, the cleaning cycle. If the user starts with the pre-wash cycle, the quantity of water used for rinsing out the softener, amounting to 2 litres, is initially not pumped out, i.e. this water is also used for the pre-wash cycle. As a result, the total water consumption of a complete washing cycle falls by about 10%. The method can be applied both to dishwashers fitted with softener equipment and, analogously, to washing machines.

Title: Electrical switching device having an electromagnetic switch drive
Inventor: GIEGOLD PETER
IPC: H01H9/02
Filed: 1988-12-14
Abstract: A switching device, especially an electrical contactor, which is accommodated in a housing (which can be closed by means of a covering cap on the front) and is equipped with an electromagnetic switch drive has cable connection points both for the mains supply cables and load cables to be connected and for the control cables leading to the electromagnetic switch drive, namely a control phase and a neutral conductor connection. The fastening means which are arranged at the cable connection points can be operated through access openings in the covering cap, from the front of the switching device. In order to prevent manipulations in the case of those switching devices which may be connected only at specific times of the day and/or night or in specific mains constellations (low-load periods), it is proposed to combine the covering cap (12) (at least in the region of its access openings (19...23)), which are assigned to the control cable phase and to the mains supply cables, to the fastening means of the cable connection points with an additional cap (28) which closes these access openings. The additional cap is connected to the covering cap which supports it and/or to the housing (11) of the switching device (10) and can be security sealed (lid sealed) such that it cannot be removed from the switching device without destroying the security seal. <IMAGE>

Title: Device for annular detonation of a shaped charge
Inventor: SCHNAPP HERBERT DIPL ING
IPC: F42B1/024
Filed: 1988-12-24
Abstract: A disturbance in the annular detonation of a main charge (2) from the underneath is avoided according to the invention by coating an inert body (8), which is known as a barrier, only partially with a relatively small amount of explosive, preferably an explosive film. The form and stability of the inert body (8) can be designed exclusively such that it is the best for the shape of the explosive coating (7). This also results in a considerable simplification in production. Using such an inert body, in addition, the influence of various parameters on the detonation behaviour of a shaped charge can be investigated systematically. <IMAGE>

Patent DE-3912497-A1 (DE)
Inventor: VOIGT BURKHARD DIPL ING
IPC: H04L27/32
Filed: 1989-04-15
Abstract: A loosely coupled transformer or rotary transformer L1, L2, via which measuring electronics, e.g. on a moving part of a vehicle, are supplied with energy, is loaded by the measuring electronics via a switch S at a rate f2 which is a sub-multiple of the energy supply frequency f1. This periodic loading is phase modulated when the level of a binary data signal to be transmitted by the measuring electronics changes. The modulated signal Umod is transferred back to the primary side of the transformer and for the recovery of the data, is demodulated by multiplication with a periodic signal UH at the frequency f2. The resulting signal, after averaging, is supplied to a comparator at the output of which the data signal is available again. Instead of employing a fixed rate f2, a pseudo-statistical signal stored in a ROM may be used. <IMAGE>

Title: Impulses actuating ignition cap for explosive charge - comprise burst derived from a supersonic generator
Inventor: BENDER RICHARD DR
IPC: F41A19/59
Filed: 1989-07-13
Abstract: The mechanical impulse for detonating the charge in an initiator cap, e.g. contg. an anvil to aid detonation from an impulse applied to the other face of the cap, derives from a short burst of impulses, lasting in total e.g. between 10 and 20 micro-seconds. The impulses derive from a known ultrasonic generator, at frequencies up to 40000 Hz. They may be applied directly to the cap or indirectly via a striker pin. Impulse shape may be triangular, rectangular, trapezoidal etc. Individual impulses in the detonator burst are weaken than the single impulse which can be used for detonating caps. USE/ADVANTAGE - Used for propellant powders, gas generators, delay charges etc. Igniter charges may be less sensitive and employ harden metal for cap, reducing risk of accidents.
