Inventor: KRUG KARL
IPC: G08B21/04
Filed: 1982-07-12
Abstract: Device for the time-dependent automatic release of the safety chain with the generation of an alarm signal. It is to be possible to enter the home of a single helpless person quickly and without damage to property in the event of a preceding time-dependent release of the safety chain and after an alarm signal has sounded. The device required for this is, on the one hand, to allow for the safety needs of single persons and, on the other hand, to draw attention to the fact that he or she is incapable of movement by the automatic release of the safety chain with the triggering of an alarm signal. The object is achieved in that a safety chain (1) attached to the door of the house or apartment can fall out of a downwardly open holding rail (2) and activate an alarm unit (8) when the single person has for several hours failed to actuate a resetting switch, located in the apartment, for an automatic time circuit. The device can also be designed with a time-switch device, so that a release and/or a triggering of an alarm signal can, if required, be set manually for a particular time. <IMAGE>

Title: Device for fire extinction
Inventor: HARIG EGON
IPC: G08B17/12
Filed: 1982-08-14
Abstract: In the detection of fire or explosions use is made of two UV-detectors which are sensitive in the same narrow waveband, preferably the oxygen line in the UV spectral region, and the pulses of the two detectors are counted in separate counters. These counters are jointly reset in each case at a specific time after the occurrence of the first pulse of one of the two UV-detectors. If both counters exceed a prescribed counter setting before the resetting, an alarm signal is triggered, and thus also the release of an extinguishing medium in the room to be monitored. A fault counter is provided, in particular for monitoring the failure of a UV-detector, which respectively receives a counting pulse when one counter has overshot the prescribed setting, while the other counter still remains below the prescribed setting. In the case of radioactive radiation, a further UV-detector is provided which shields against optical radiation but is just as accessible to radioactive radiation as the other UV-detectors, and whose pulses are counted in a further counter whose setting preferably increases the prescribed setting of the first-mentioned counter for producing an alarm signal. The UV-detectors preferably receive the radiation from the room to be monitored via optical fibres. <IMAGE>

Title: Apparatus for the preheating of heating oil
Inventor: ROTTER GUENTER R
IPC: F23K5/04
Filed: 1983-07-29
Abstract: To achieve optimum atomising of the heating oil in the burner nozzle of an oil-fired furnace, the heating oil is preheated, to reduce its viscosity, in heat exchangers acting as instantaneous heaters and having boiler water flowing through them. In order to preheat the heating oil even after inoperative periods, known apparatuses have an additional electrically heated heat exchanger. The disadvantages associated with such apparatuses are overcome by the invention, in that only a single heat exchanger, with boiler water flowing through it, is installed in the duct leading from the burner pump to the burner nozzle, and has an electrically heated rod-shaped body built into it as the additional heat source, surrounded by a helicol pipe coil through which heating oil flows, and a boiler water circulation pump built into it. In order to shorten the preheating time after inoperative periods of the oil-fired furnace, the combined heat exchanger has a bypass duct which connects the inflow duct and the outflow duct for the boiler water and which forms a closed circulation, heated by the electrically heated body, for a small portion of the boiler water. <IMAGE>
