Title: Preheating system for IC engine - stores waste heat as latent heat and uses salt solution changing from crystalline to liquid form releasing heat to oil circuit
Inventor: MUELLER KLAUS DR
IPC: F02N19/04
Filed: 1979-04-21
Abstract: The preheating system for an internal combustion engine stores the waste heat obtd. when the engine is in operation. It uses a latent heat store, which functions as a heat exchanger to supply or absorb the necessary energy. It also includes a switch to release the required heat. The latent heat store is incorporated in the coil circuit. The latent heat store (6) uses a salt solution, which changes from a crystalline form to a liq. form thus releasing the latent heat. The heat is given off to the coil circuit of the engine via the oil pump (4) driven by a motor (15), which pumps lubricating oil whose viscosity will be reduced. This will therefore reduce the consumption of the starter.

Patent DE-3120986-A1 (DE)
Inventor: MOSER OTTO-WALTER DIPL ING
IPC: G08B29/00
Filed: 1981-05-26
Abstract: A method and apparatus for inspecting a danger alarm system, such as a fire alarm system, having a plurality of discrete alarm units which are connected to a central station having a means for cyclically sampling and connecting the alarm units to a like plurality of evaluators permits the alarm units to be connected individually or in groups to an inspection display without suppressing the display of an actual alarm signal which may be received during the inspection. A first report of an alarm unit to be inspected is evaluated as an inspection report and an actual alarm report from the same alarm unit arriving after the inspection report is evaluated and displayed as an alarm report. Given alarm units which emit multi-level or analog signals, the alarm unit signals are evaluated in the central station with two threshold circuits, the evaluator at the central station being switched during an inspection to a less sensitive state and the inspection signals being evaluated by a lower threshold stage and a true alarm signal which may occur during an inspection being evaluated as such by an upper threshold stage.
Patent DE-3126725-A1 (DE)
Title: Stringed instrument
Inventor: HOPF DIETER
IPC: G10D3/22
Filed: 1981-07-07
Abstract: In such stringed instruments, which have a crossbar (20) as a base element for the web (23, 24) fastened on the top (15) of the instrument body (11) and a string-holding device (25), in particular in the case of guitars, there is provided, on the rear side of the web (23, 24) with regard to the scale, an elastic tension relief device (21) which extends from the instrument body (11) to the crossbar (20) and which, in the region of the crossbar (20), forms, with regard to the connection surface of the crossbar (20) to the body top (15), a bypass which is effective for at least a part of the tensile stress of the strings (18) to be carried off to the instrument body (11). This tension relief device (21) can essentially be formed by the strings (18) themselves which are guided further via the string-holding device (25). It is also possible, however, to provide one or more special counter-tensioning elements, the tensile stress of which can be adjustable. By means of the tension relief device (21) which is effective on the crossbar (20), the bracing strain of the body top (15) in the region of the crossbar (20) is considerably reduced and the combination of the crossbar (20) with sound holes (17) arranged in its immediate vicinity and/or in its interior becomes possible. <IMAGE>
