Title: Loom stop mechanism - has an auxiliary drive controlled by logic circuitry to adjust loom position at rest to repeat yarn break conditions
IPC: D03D51/18
Filed: 1975-10-15
Abstract: An appte. is claimed to operate a loom automatically in the event of a yarn breakage, to position the shed correctly for the break to be rectified, with the operation set in motion by detection of the yarn breakage and the generation of a stop signal which brings the loom to rest. A mechanical drive is provided to move the loom action in either direction, operated by a small electric motor so that, in conjunction with the stop signal and a logic circuit, the auxiliary unit can bring the loom into the precise condition at which the breakage occurred. The system provides an automatic mechanism to position the loom with the shed open at the yarn break, for the operative to take the necessary action without having to inch the loom by hand first into the required position.

Title: Overcurrent protection with thermomechanical transducer - provides form changes of transducer under increased current conditions
IPC: H01H71/14
Filed: 1977-01-19
Abstract: The overcurrent protection is intended for circuits which under overcurrent conditions could damage associated apparatus. The protection has a switching element (10) of material which converts the supplied thermal energy into a mechanical one, under simultaneous change of shape of the switching element, such change taking place on the current in the circuit exceeding a preset value. Under such conditions the element temperature is increased and its change of shape interrupts the current flow through the circuit. Preferably the switching element is also under current flowing in the circuit. A heating may be associated with the switching element and incorporated in the circuit. On exceeding a preset maximum current value in the circuit, the temperature increases, the shape of the switching element changes, and interrupts the current supply.

Patent FR-2352966-A1 (FR)
IPC: A61M1/00
Filed: 1977-05-24
Abstract: Intravenous Fluid Pumping System having a controller and a pump controlled by the controller. The controller has a sealed chamber with a flexible membrane covering a portion thereof. An incompressible fluid is disposed in the chamber. A piston member is movable in the chamber causing extension and retraction of the membrane as the piston is moved in and out relative to the chamber. A motor is provided for reciprocating the piston. The pump has a pump body with a pumping chamber therein with one portion of the pump body being covered by a flexible membrane in contact with flexible membrane carried by the sealed chamber of the controller. The pump has an inlet adapter connected to the source of fluid. The pump also has an outlet adapter connected to the patient. Inlet and outlet valves are provided in the pump body whereby when the controller is operated to flex the membrane of the sealed chamber of the controller, the diaphram of the pump is operated to cause movement of the valve members to cause fluid to pass from the source through the pump and to the patient under the control of the pump. The controller is also provided with an alarm system whereby positive and negative pressure conditions in the pumping chamber can be sensed. In the method a piston-like member is used to positively cause displacement of a liquid within a sealed chamber to cause movement of a flexible membrane forming a portion of the sealed chamber. The movement of the flexible membrane causes simultaneous movement of another flexible membrane in intimate contact with the first-named flexible membrane. The movement of the second flexible membrane is used to create a pumping action in a pump having a pumping chamber in which the last-named flexible membrane forms a part of the pumping chamber.
