Patent DE-4131392-A1 (DE)
Title: Evaporation preventing appts. for liquefied gas reservoir
Inventor: WATANABE EIICHI
IPC: F25J1/00
Filed: 1991-09-20
Abstract: A cold end (15) of a cold head (12) of a cryogenic refrigerator (11) is disposed in an upper opening (10) of the liquefied gas reservoir (4), the cryogenic refrigerator being adapted to be put into automatic operation depending on the temperature inside the liquefied gas reservoir, wherein the automatic operation mode of the cryogenic refrigerator can be released by remote control during the use of the detector. The cryogenic refrigerator is put into automatic operation (an alarm having previously issued) when the temperature inside the liquefied gas reservoir increases above a set temperature with the detector being out of use, thereby allowing vaporised gas to be reliquefied with the gas consumption reduced.     Bellows (16) prevent vibrations being transmitted from a compressor (13) of the cryogenic refrigerator to the cold head (12). The cold head is mounted on a stand via a horizontal biaxial linear guide mechanism. A liquid level sensor (20) and a temperature sensor (17) are provided for the reservoir (4). The detector is mounted on a cold finger extending from the reservoir (4).

Title: Operating device for opening and closing pipe valve - has release member and associated spring responding to upper and lower temp. thresholds.
Inventor: SLOTKOWSKI JOHANN
IPC: F16K17/38
Filed: 1991-12-09
Abstract: The spring (6) is released by the release member (14) on reaching the upper temp. threshold. On cooling below a selected lower temp. threshold the release member tries to return automatically to the starting position owing to a second opposite shift in position. The temp. monitoring function of the operating member can be reproduced so that the first spring is automatically tensioned by the operating lever following the closed position. The first spring is again blocked in its starting position by the release member through detent engagement. USE - The operating device can be used universally to close pipes both without current and with remote control.
Patent DE-4202029-A1 (DE)
Inventor: HAHM MANFRED
IPC: D01H1/38
Filed: 1992-01-25
Abstract: The invention concerns a yarn bobbin with a rotationally symmetrical body the outside of which forms a surface which carries the yarn and which has a longitudinally protuding collar at one end. The aim of the invention is to design a bobbin of this kind which has the advantages of prior art bobbins but which, when wound, can be stacked with other, similar, bobbins without the yarn being damaged or snagged. The invention achieves this by virtue of the fact that the bobbin (1) has, at its end with the yarn uptake (2), an additional collar (3) which has the same external dimensions as the internal dimensions of the collar (4) at the other end of the bobbin but is staggered radially inwards with respect to the yarn uptake, the collar (4) being fitted with a yarn-reserve groove (6).
