Abstract: A fusible link having two body members separably coupled to one another and normally prevented from separating by a collapsible strut. One body member has an opening in which the other body member is slideably accommodated, such other body member having an abutment which bears against the body at one marginal edge of the opening.

The strut includes a eutectic alloy which melts when its temperature rises to a predetermined level. Melting of the eutectic alloy permits the overall length of the strut to shorten by an amount sufficient to permit the abutment on the slideable body to pass through the opening in the other body and effect separation of the bodies.

Abstract: A closed loop refrigeration process and apparatus provides a large flow of cold, supercritical gas through a device which is to be cooled at cryogenic temperatures. The output of helium gas from a compressor is precooled with liquid nitrogen and divided into two streams which are cooled by expansion and by heat exchange with the return flow of helium to the compressor. The two streams are recombined and further cooled by heat exchange with the return flow and a liquid helium bath. The entire output of the compressor, at liquid helium temperature and above critical pressure, is forced through the load. The stream is then expanded through a valve where partial liquefaction takes place to replenish the liquid helium cooling bath. Gaseous helium is drawn off from the liquid helium bath and recycled through the heat exchangers back to the compressor.

Abstract: The accumulation of ice on a surface such as an evaporator fin in a refrigerator unit is detected by a mechanical probe which is moved by a bimetal bender element upon periodic timer-controlled energization of a bimetal heater so as to pass over the surfaces of an evaporator fin. If the movement of the probe is obstructed by ice on the evaporator fin surfaces a switch is operated by a bistable mechanism, causing energization of a defrosting heater and switching off the refrigerator compressor motor. If no ice is detected the probe returns to its original reset position without operating the defrost control switch.

The method restricts the width variation of the strips at the delivery side of the roughening rolls caused by the difference in temperature distribution in the widthwise direction of the strips between skidded areas and non-skidded areas by controlling the degrees of roll opening of a vertical roll stand based on the measurement of the width of the material to be rolled measured by a width meter, the vertical roll stand being disposed downstream of the measuring point.

Abstract: A method and apparatus is described for use in combination with a machine for corrugating a continuous strip of flat sheet material which prepares the sheet material for separation into sections after it has been corrugated. A platform is located upstream of the corrugating machine. The platform is intermittently advanced in the direction of travel and at the speed of the sheet material so that the platform is stationary relative to the sheet material. A scoring device is located on the platform. The scoring device moves across the width of the sheet material as the platform moves with the sheet material to form a spanwise weak point in the material. After the material passes through the corrugating machine, it can readily be separated into sections at the weak points formed in the material by the scoring device. Depth of scoring can be varied also so that substantial/total separation can also occur within the corrugator though it would not separate the flat strip before it entered the corrugator.

Abstract: A method is proposed which serves to produce a valve needle of a needle valve. The basis of the method is the production, from a wire serving as the raw material, of a springlike coil on a carrier body, where the adjacent courses of the coil rest on one another, and this coil applied to the carrier body is provided on its circumference with a predetermined contour by grinding on a grinding machine. After the grinding, the individual courses of the coil, forming the individual valve needles, are separated. The wire serving as the raw material and the valve needles after separation of the courses of the coil can be subjected in a suitable manner to a heat treatment. In a simple and inexpensive manner, the method assures the production of curved valve needles with precise dimensions.
