Patent DE-3230704-A1 (DE)
Title: Apparatus for oil firing plants for preheating the heating oil
Inventor: ROTTER GUENTER R
IPC: F28D21/00
Filed: 1982-08-18
Abstract: The heating oil preheating device has a heat exchanger (11) through which oil flows and which is arranged as a pipe coil on the outer side of the flue gas pipe (12) of the heating boiler of an oil-fired plant. The heat exchanger is connected at one end via a changeover valve (23) to the burner backflow channel and at its other end to a mixing chamber (27) in which oil delivered from a supply tank is mixed with preheated oil. The changeover valve (23) is bridged by a bypass duct (36) having a restricted cross-section and permanently connecting the heat exchanger (11) to the burner backflow channel (19). <IMAGE>

Title: Electromedical device
Inventor: KUSSEROW BERND DIPL ING
IPC: A61B5/276
Filed: 1982-09-01
Abstract: The invention relates to an electromedical device, especially a stimulation current device, having a current waveform generator for the generation of stimulation currents which can be supplied to the body of a patient via output lines and electrodes. In order to guarantee safety of the patient it is necessary to use an insulated application part. According to the invention, means for separate recording of the current flowing into the patient, on the one hand, and out of the patient, on the other hand, are present in the output lines. In the manner of a fault-current safety switch a comparator (10, 20) records the equilibrium between currents flowing in and out and activates a switch-off member (6) in the output line in the case of an imbalance. <IMAGE>

Patent DE-3318003-A1 (DE)
Title: Low-temperature heating plant with non-toxic, environmentally friendly exhaust gas, consisting of a catalyst as heat producer, a temperature limiter and also a heat exchanger
Inventor: SCHULTE RUDOLF DIPL ING
IPC: F23C13/00
Filed: 1983-05-18
Abstract: A catalyst as heat producer, an exhaust gas temperature limiter and a heat exchanger are coupled such that the heat production takes place in a low temperature region of about 100-350 DEG C and thus a production of toxic exhaust gas components such as sulphur dioxide or nitrogen dioxide is not possible. The exhaust gas temperature limiter throttles the fuel supply such that the maximum exhaust gas temperature of about 350 DEG C is not exceeded. Combustion gases, gasified or evaporated liquid fuels and also residual gases, that is, combustible gases far below the ignitable concentration, serve as fuels. The neutral exhaust gas permits passing through the dew point even in the heat exchanger and thus use of this energy component too. The plant can also be continuously run in the small load region, so that the otherwise usual start-stop operation is eliminated. The main advantages bring further benefits, so that the plant is smaller, more reliable, and safer than conventional plants of this kind.

Title: Retention device
Inventor: BRIGGS STUART JOHN
IPC: B60T11/16
Filed: 1983-11-08
Abstract: A retention device for holding an elongate component (4) in a hollow body (1) takes the form of at least an approximately annular component (12) of elastic material which is radially slotted and has a gap which allows the component (12) to be compressed radially for insertion into an annular inner groove (13) in the hollow body (1). The component (12) has inward projections (15), the inner faces of which form seating areas which are designed to correspond to a face (11) on a head (8) of the elongate component (4). The component (4) is thereby held in the cylinder by the retention device and, at the same time, has a certain angular mobility relative to the hollow body (1). The retention device is of use primarily in conjunction with a hydraulic brake master cylinder.
