Title: Apparatus for diathermy
IPC: A61N5/00
Filed: 1923-10-08
Abstract: 205,111. Naamlooze Vennootschap Nederlandsche Seintoestellen Fabriek, and Reijnders, F. R. Oct. 8, 1923. Thermionic generators.-High-frequency currents for treating diseases by diathermy are produced by a back-coupled thermionic valve. The' plate and filament circuits are fed from alternating current supply mains 1, 2 through transformers 4, 3 respectively. A switch 5 is automatically closed as the box containing the high tension coils is shut so that it is impossible to touch these parts accidently when under voltage. A foot contact 6 enables the physician to control the apparatus at will. High-frequency currents in the circuit 11, 12, 13 are fed to the patient through an intermediate coupled circuit 20 which is earthed at 24. The local temperature may also be automatically regulated by means of thermo-cells (not shown) which control the filament or plate supply circuits of the valve, or else change the coupling factor between the coils 11 and 20. The device mav be conveniently combined with R÷ntgen-ray apparatus, the same supply circuits serving to feed both tube generators. Specifications 154,535 and 187,098 are referred to.

IPC: F02C7/143
Filed: 1949-10-04
Abstract: 680,127. Gas turbine plant; centrifugal compressors. ROLLS-ROYCE, Ltd. Oct. 4. 1950 [Oct. 4, 1949], No. 25552/49. Classes 110 (i) and 110 (iii) In a gas turbine plant comprising low pressure and high pressure compressor stages connected in series and driven by mechanically independent turbines, one or more by-pass valves are connected with the interstage ducting so as to permit the flow of working medium from or into the ducting without passing through the low pressure stage, the valves being loaded in the sense of closure by a pressure derived from the high pressure stage and in the sense of opening by the pressure within the ducting. Air is compressed by a low presure stage 10, Fig. 1, and a high pressure stage 13, driven by low and high presure turbines 19 and 16 respectively and delivered to a combustion chamber 15. The combustion gases pass through the turbines 16 and 19 and, it may be, an intermediate turbine 17 driving a power output shaft 17a. An intercooler 11 and an air preheater 14 are provided. In the event of the turbine 17 overspeeding, the fuel supply to the combustion chamber 15 is reduced or shut off by a centrifugally operated trip mechanism. The resulting back-surge of the working medium contained in the combustion chamber 15 and ducting 20 causes a pressure rise in the ducting 12. To avoid exceeding the maximum permissible delivery pressure of the stage 10, the ducting 12 is vented to atmosphere through a valve 21, which is normally kept closed by the delivery pressure of stage 13, communicated to a piston 24a, Fig. 3, by way of a conduit 25. The piston may be replaced by a flexible diaphragm. To ensure operation, the valve is preferably urged towards the open position by a spring 26. Alternatively or in addition, the effective area of the valve element 22 is greater than that of the piston or diaphragm. To permit the plant to run under low power conditions with the stage 10 by-passed, the application of pressure to the piston or diaphragm may be controlled by a valve which is operated either manually or automatically at a predetermined pressure ratio of the stage 13. The spring 26 holds the valve open when the plant is stationary, and so permits the stage 10 to be by-passed when the plant is started by rotation of the shaft 16a by an external means. A separate valve may be provided for this purpose.

Title: Improvements in or relating to braking apparatus for use with pit head winding mechanisms and the like
IPC: B66D5/26
Filed: 1950-10-24
Abstract: 691,941. Winding brake mechanism. BLACK, G. A. Oct. 24, 1951 [Oct. 24, 1950], No. 25904/50. Class 103 (i). In braking apparatus for pithead winding equipment wherein normal braking is effected by a mainspring unit, such as the spring nest 14, under the control of a hydraulic cylinder 19, auxiliary spring means such as the spring nest 26 under the control of cylinders 28 are provided, so as to alter the maximum braking effort available. The invention is applicable to brakes of the type shown in Fig. 1, wherein pairs of shoes 2 and 3 (only one shoe of each pair being shown) are normally applied to a Koepe wheel 1 by the action of spring nests 14 upon a rod 17 and bell-crank 13 when the hydraulic pressure supplied by a pump 20 to a cylinder 19 is released. The auxiliary spring nests 26 which extend between the fixed plate 27 and screwed rods 30 on which is adjustably secured the bar 15 secured to the upper ends of the springs, act to press the bar 30 upwards and thus extend and reduce the compression of springs 14. This movement is, however, normally prevented by hydraulic pressure acting in cylinders 28. When an emergency trip valve 25 on the pump is operated, the liquid from both cylinders 19 and 28 is released so that the brake is automatically applied but at a pressure below that for normal braking purposes. Instead of for emergency use the invention is applicable to arrangements where different degrees of braking are required, as for balanced and unbalanced winding. As applied to a winding drum arrangement of the type shown in Figs. 5 and 6, having a drum 31 keyed to the shaft 33 and an oppositely wound drum 32 that may be clutched in by a clutch member 34, the drum 31 which may be in use for unbalanced winding is provided with a brake having both main and auxiliary springs 42 and 43. The operation of the clutch for the drum 32 causes the hydraulic compression of spring 43 so that the effort by spring 42 is increased. Conveniently the hydraulic cylinder S controlling the springs 43 are also automatically controlled by a valve operatively associated with the reversing switch. A further embodiment applied to a single reversely wound drum is also described.
