Title: Thermodynamic engines and methods for heating a heat exchange fluid and/or keeping one or more environments refrigerated
IPC: F25B41/04
Filed: 1984-05-17
Abstract: The result which the invention aims to obtain consists in producing thermodynamic engines which can satisfy, selectively, the low-temperature requirements by keeping environments, for example, refrigerated and the high-temperature requirements by heating a heat exchange fluid. These engines satisfy on the one hand the low-temperature requirements as a priority, and secondarily, all or part of the heating requirements by means of energy recovery, and, on the other hand, an additional heat production, when the latter is necessary and allowed, by operating as a heat pump. They consist of: a compressor assembly 3 intended to compress the vaporised refrigerant fluid; an assembly 2 for exchanging the heat from the refrigerant fluid to the heat exchange fluid; a condenser assembly 4 whose cooling agent is external; a first evaporator assembly 6 whose heating agent is an external energy source and a second evaporator assembly 5 in contact with the environments to be refrigerated.

Patent FR-2568010-A1 (FR)
Inventor: HEYRAUD GEORGES
IPC: B25B23/142
Filed: 1984-07-23
Abstract: A torque wrench according to the invention has a rigid elongated body having a tool end adapted to be rotationally fixed to a part to which a predetermined desired torque is to be applied and an opposite handle end. Transducers including strain gauges connected between the tool end and the body generate an actual-value output corresponding to the actual torque being applied by the wrench to the part rotationally coupled to the tool end. A display connected to the transducers reads out torque and an input device generates a desired-value output corresponding to the desired torque to be applied by the wrench to the part rotationally coupled to the tool end. A first comparator connected to the transducer and input device compares the actual-value and desired-value signals and generates an alarm signal when the actual torque is substantially the same as the desired torque. In accordance with this invention a second comparator compared the actual torque with a relatively low threshold torque. A switch circuit connected between the display on one side and the transducer and second comparators on the other side feeds the desired-value signal to the display when the actual torque lies below the relatively low threshold torque and alternately feeds the actual-value signal to the display when the actual torque exceeds the threshold torque.
