Title: Apparatus for destroying limited groups of cells
IPC: A61N7/02
Filed: 1963-10-23
Abstract: 1,055,391. Treating with ultrasonic energy. G. A. D. GORDON. Oct. 1, 1964 [Oct. 23. 1963], No. 41920/63. Addition to 998,173. Heading A5R. Apparatus for locating and destroying tissue cells within the body by ultrasonic energy comprises an ultrasonic transducer assembly arranged for producing both strong and weak impulses, the transducer being marable by a sterotaxic device so that the weak impulses may be used to locate the cells by an echosounding principle and the strong impulses then applied to a chosen point within the tissue to destroy the cells. The transducer 9 is mounted in a support 8 which is movable, by operating handles 2, 3, 4 of the stereotaxic device. in three planes at right angles to one another, the focus of the transducer thus being correspondingly moved. The transducer is pivotal with a plate 10 within the support 8 without altering the position of its focus so that the ultrasonic beam may be directed for maximum effect, i.e. so that it strikes the group of cells normally. An extension 29 from the support is connected through a universal joint 27 and a parallel linkage with a pointer 30 which moves over recording paper mounted on a support 37, 38. The paper is such that it may be electrically connected to a voltage source and will only permit the pointer to mark it when the voltage exceeds a predetermined value. The position of the pointer indicates the position of the focus of the transducer. The parallel linkage is supported by a universal joint 28 fixed to a second stereotaxic device 31- 35 by which it may be positioned vertically below the first joint 27. The linkage is rotatable about the joints 27, 28 so that it may be located parallel to either of the vertical planes of movement of the support 8. In use, the transducer is first connected to a source of weak impulses, e.g. a conventional flaw detector, and the transducer is moved so that its focus scans the region of the body in which the cells are to be located, e.g. the brain. When the focus coincides with the surface of the group of cells concerned, an echo impulse is transmitted via the transducer to the recording paper, thus permitting a mark to be made on the paper by the pointer. When scanning is completed. the marks on the paper give a record of the shape of the group of cells in the vertical plane or planes chosen for the investigation. The transducer is then connected to a source of high power impulses and its focus positioned by adjusting the pointer to a desired position relative to the recorded shape for destroying the located cells. Two interchangeable transducers may be used for applying the weak and strong impulses respectively. The transducer which is not being used is stored in a temperature-controlled bath 12 of saline solution.

Title: Gas turbine engine fuel system
IPC: F02C3/14
Filed: 1973-09-06
Abstract: 1401578 Gas turbine engine fuel systems GENERAL MOTORS CORP 6 Sept 1973 [20 Oct 1972] 41971/73 Heading F1G A gas turbine engine fuel system comprises means for supplying fuel from a fuel tank to the engine; combustion apparatus in the engine receiving the fuel and defining a sump adapted to collect unburned fuel; a return line from the sump to the tank adapted to return to the tank fuel expelled from the sump by pressure in the engine; and normally open valve means in the line of a type closing in response to a predetermined low pressure differential between the sump and the return line to prevent exertion of significant pressure on the tank. The engine case is divided by a bulkhead 4 into a housing 6 for the compressor, combustion apparatus and turbine and a housing 7 for the turbine exhaust scroll or diffuser. Unburned fuel collecting in sumps 32, 34 in the respective housings can pass, when the engine is stationary, through a normally-open valve 35 from the sump 32 and through a normally-open valve 36, a duct 70 and the valve 35 from the sump 34 and thence via a duct 38 to a catch basin 80. If there is a sufficient quantity of fuel, it flows through a normally-open valve 39 and a connector 79 to the fuel tank. When the engine is started, compressor discharge pressure flushes any fuel remaining in the sumps 32, 34 and catch basin 80 to the fuel tank. At about 2psig compressor discharge pressure the valve 36 closes, since the housing 7 is at atmospheric pressure, and thereby prevents by-passing of compressed air from housing 6 into housing 7. When the pressure has increased further to about 5psig, the valve 35 closes and thereby prevents the fuel tank from being pressurized by the compressed air. Valve 39 closes at a slightly higher pressure in the event that valve 35 does not completely seat. In this event, the resultant build-up of pressure in the duct 38 is transmitted via a branch line to a pressure-operated switch to operate a signal lamp and, it may automatically terminate the engine starting sequence.
