Title: Temp. distribution measurement along any path without interpolation - is by measuring temp. of heat carrying fluid column actuated by pump
Inventor: SCHUSTER KARL DIPL ING DR TECH
IPC: G01K1/02
Filed: 1977-12-02
Abstract: A method and device for measurement of temp. along any path avoids the cost of interpolation between many measurement points for high accuracy by enabling continuous measurement. A suitable heat carrying fluid placed in a tube or drilled hole along the path for a given time picks up the temp. of the tube surroundings and then passes by a temp. sensor (4) after the defined time interval. The length dependent thermal carrier column temp. distribution is converted into a time dependent measurement signal. This is converted back into a length dependent record.

Title: Cage in mine shaft with rope winding gear - has rope tension compensator matching amount of stretching to given load
Inventor: HOISCHEN ANSELM DR
IPC: B66B17/34
Filed: 1978-09-08
Abstract: The mine shaft lifting transporter has a rope carrying heavy loads. The transporter or cage has no features which damage the shaft walls. The stretching of the lifting rope is compensated and rope tension is matched to the suspended load by the transporter drive. The transporter rope tension regulating signal is generated by the drive on loading or unloading of the transporter when the rope is extended. The signal generated locks the extended holding latches and the signal also determines the rotating direction of the drive to ensure compensation.

Title: Lead accumulator cell with gas-tight stoppers - which contain catalyst for recombination of hydrogen and oxygen, and/or valve limiting gas pressure in cell
Inventor: NANN EBERHARD DR PHIL
IPC: H01M10/52
Filed: 1979-02-09
Abstract: Cell is fitted with at least one gas pressure limiting valve in its gas cavity, and also with a holder with restricted permeability for the gas. The holder contains a catalyst for recombination of the H2 and O2 evolved during operation of the accumulator, so water is obtd.; and the holder acts as a mechanical barrier restricting the flow of gas to the catalyst. The pref. pressure limiting valve functions according to the pressure or temp. of the gas, and is located in one of the stoppers on the accumulator lid; and the valve may alternatively be fitted in the stopper contg. the catalyst. One pref. catalyst holder consists of a porous ceramic frit. The recombination of H2 and O2 to form H2O liberates heat, and the catalyst can be destroyed if it is overheated. Arrangement limits the flow of H2 and O2 to the catalyst.

Patent DE-2938203-A1 (DE)
Inventor: KNOCHE KARL-FRIEDRICH PROF DR
IPC: F25B17/00
Filed: 1979-09-21
Abstract: A method and apparatus for the use of heat taken up at low temperature is disclosed wherein a flow of transfer medium is passed through a low temperature heat source to absorb heat. The flow then passes through multiple, sequential stages of a heat pump which successively increase in temperature whereby the flow picks up heat. The flow then releases heat to the heat receiver and subsequently passes through multiple sequential degassing stages of the heat pump. The flow releases evaporation heat and is cooled to a suitable temperature for use in the low temperature heat source. The heat pump preferably includes a two substance mixture provided within a two portion, hermetically sealed chamber.
