Patent DE-3240833-A1 (DE)
Title: Heat transfer device
Inventor: LUEBKE PETER
IPC: F28D15/00
Filed: 1982-11-05
Abstract: The present invention relates to a heat transfer device with a fuel-heated heat source and an exhaust-air heat source, a heat exchange device and a guidance for intake air or ambient air. In such heat transfer devices, there is a danger of enrichment of the intake air with harmful components of the exhaust gas when there are leaks in the region of the heat exchanger for direct heat exchange between the exhaust gas and the intake air. As the invention, it is therefore proposed to embody the heat exchange device as two heat exchangers with a transfer medium circuit.

Patent DE-3347567-A1 (DE)
Title: Method for the improved utilisation of energy in four-stroke piston engines
Inventor: VELDTEN BURKHARD
IPC: F02B1/04
Filed: 1983-12-30
Abstract: A method for a four-stroke piston engine, in which less gas is drawn in on the intake stroke than would be possible by virtue of the swept volume. The gas is then compressed to a hitherto normal compression pressure, however, which results in an increase of the compression ratio. Such an engine can now utilise, in the working stroke, the full swept volume for expansion of the gas and thereby expand it further than existing engines. This reduces the amount of energy dissipated by way of the exhaust, which is directly related to the thermal efficiency.

Title: Thermal printing apparatus having for the thermal print head a carrier which is movable in the line direction along a printing carrier
Inventor: KITTEL ARTHUR ING GRAD
IPC: B41J2/325
Filed: 1984-02-04
Abstract: In order to prevent unnecessary wear of the print head (6) and smearing of the printed image generated during a relative movement between the print head (6) and the recording medium (1), the print head (6) is brought out of printing contact with the recording medium (1) during said movement. For this purpose, in known devices, the carrier (4), which is movable along the recording medium (1), is pivoted with the inking unit and the print head (6) about the guide axis thereof. The pivoting of this heavy carrier (4) requires a powerful drive device and a considerable amount of time which is too great for high-speed printing mechanisms. The invention is based on the object of simplifying the abovementioned lifting of the print head (6) from the recording medium (1). This object is achieved in that the carrier (4) is mounted displaceably on fixedly arranged guides (2, 3), and in that the print head (6) is arranged pivotably on said carrier. Due to the low mass of the print head (6), on the one hand rapid lifting thereof is possible and, on the other hand, only a low-power drive is required. <IMAGE>

Abstract: An HRC-fuse as an insulating body surrounding a main fusible conductor and an auxiliary fusible conductor connected to a spring biased impact pin. A conductive cap serving as a terminal for the fusible conductors is arranged on the insulating body and is provided with an outlet opening opposite the impact pin. A tripping hollow pin or sleeve coaxially surrounds at least a part of the impact pin and passes through the outlet opening. A bimetal release pawl is arranged in the one cap parallel to the pin and being electrically connected to the fusible conductors. The pawl engages a rest on the tripping sleeve to counteract a biasing spring. The impact pin and the tripping sleeve are triggered independently one from the other either by a short-circuit current melting the auxiliary conductor, or by an overload which heats up the bimetal release and triggers the sleeve. Both the tripping sleeve and the impact pin act on a load interruptor arranged opposite the outlet opening.
