Filed: 1972-07-14
Abstract: 1385551 Regulating the flow of fluids LENINGRADSKY ORDENA LENINA POLITEKHNICHESKY INSTITUT IMENI M I KALININA 14 July 1972 32974/72 Heading G3H An electro-hydraulic converter, suitable for varying the hydraulic resistance of a dielectric liquid in a pressure pipe section, comprises inlet and outlet dielectric sleeves 2 and 3, respectively, extending from the ends of a housing section 1, the section constituting an outer electrode. Disposed within the housing is a metal rod 4 which constitutes an inner electrode, the rod being retained relative to the housing section by two network elements 5 which are of a dielectric material. The inner and outer electrodes 4 and 1, are connected to the terminals of a D. C. source 8. Pressures at the inlet 6 and outlet 7 are measured by gauges 11 and 12. In use, liquid in laminar flow through the dielectric network elements 5 becomes charged and so, when the electrodes are connected to the source 8, suffers a control due to the electric field existing between the electrodes which causes the flow to become turbulent, the degree of control being related to the field intensity. In other embodiments, dielectric threads are arranged on the inner electrode, and the latter may take the form of a metal band arranged in a groove of a dielectric member.

IPC: G07F11/30
Filed: 1961-09-16
Abstract: 931,724. Coin-freed apparatus. HARRIS HUTCHINSON PTY. Ltd. Sept. 16, 1961, No. 33291/61. Class 27. A coin-freed bottle-vending machine comprising several superposed inclined delivery trays 2, Figs. 5 and 8, each served by a magazine 5, is provided for each tray with bottle-locking mechanisms in which, when the purchaser inserts an appropriate coin and then pulls upon the neck 6 of a bottle in a selected tray, permits the complete withdrawal of that bottle but prevents the withdrawal of bottles from the other trays. The trays are arranged in a frame 1 which, as shown in Fig. 5, has openings 9 in its end wall through which the bottles may be extracted endwise. Upon insertion of a coin C, it passes down a shoot 23, Fig. 15, to a slot 24 in a rotatably-mounted wheel 25 and releases an arm 29 from its normal locking engagement with the wheel and, as a result, releases the wheel from its locking engagement with a channel-section release member 16 which is mounted for limited vertical movement adjacent all the openings 9. Adjacent each opening 9 is mounted a shaft 10 which carries a member 12 contacting with and preventing withdrawal of the neck 6 of a bottle and an arm 13 mounted at its end with a pin 14 arranged to coact with a corresponding projection 18 and slot 19 in the release member 16. Slidably mounted in the release member is a series of superposed lock bars 20 which rest upon each other and are permitted a vertical movement only equal to the depth of one slot. In normal position, each lock bar is disposed adjacent an opening 9 and serves to mask a slot 19 and so prevent the corresponding pin 14 from entering the slot. After release of the member 16 by insertion of a coin, pulling upon the neck 6 of the selected bottle results in swinging of the corresponding pin 14 so that the latter engages the ramp 21 at the lower end of the associated lock bar 20 and enters the slot 19. The selected bottle can then be withdrawn, and, as the member 16 is then in its raised position, the other lock bars 20 are in such a position that they mask their corresponding slots 19 and so prevent engagement therein of the pins 14 and therefore such swinging movement of the members 12 as would prevent withdrawal of the corresponding bottles. The bottle next to the bottle actually being extracted, is held in position by a catch 33, Fig. 8, which is arranged to be depressed by a finger 35 on the shaft 10.

Abstract: 1,107,340. Pulse radar. SPERRY RAND CORPORATION. 4 Aug., 1965, No. 33330/65. Heading H4D. In a monopulse tracking radar transmitting a microwave beam on a positionable axis and producing two target echo signals of the same frequency, one echo signal (#) 7 having an amplitude representing target deviation from the beam axis and having a phase relative to the other echo signal (A) 8 representing the sense of such deviation, a modulator 6 causes amplitude modulation of signal 7 at a frequency f, a hybrid junction 18 produces signals representing # + # and # - # which are applied via detectors 28, 29, to a difference circuit 30, and the output from the latter is compared in phase in circuit 34 with a signal of frequency f to give a tracking signal. The embodiment effects tracking in azimuth and elevation and the invention avoids the necessity for precise gain and phase equalization of parallel signal channels. A # signal from a further detector 27 affords gain control of amplifiers 23, 24, but exact gain equalization of channels 21, 23, 28 and 22, 24, 29 is not essential and it is stated that the system will continue to operate, though with reduced tracking efficiency, if either of such channels fails. The azimuth 7 and elevation 5 R.F. error signals are modulated by applying them via respective space-quadrature rectangular waveguide inputs 11, 10 to a section of circular waveguide 9, output being taken from a hook-shaped probe 14 rotated at frequency f by a motor 15 energized from generator 16.
