Abstract: 152,644. Zack, M. Oct. 10, 1919, [Convention date]. Pumps for volatile liquids; valve -gear.-Volatile liquid, such as liquid air, is pumped from a low-pressure vessel 1 by means of a pump 8, to which a portion of the same liquid in a high pressure vessel 3 is admitted at the beginning oi the suction stroke for the purpose of liquefying at least a portion of the vapours in the pump barrel .and repelling the residue through a spring- pressed valve 10 into a space 9' in the piston 9. During the remainder of the suction stroke the inlet valve 11 is open and liquid is drawn from the low-pressure vessel 1, the rotary valve 13 connecting the vessel 3 to the pump being closed during this period. The liquid is delivered during the down stroke through a valve 12 into a vessel 5 in which the pump is immersed, and in which the pressure is between the pressures in the vessels 1, 3. At the end of the suction stroke the vapour in the piston escapes through passages 17. 18. The valves 11, 12 are actuated by cams 14, 15 driven from the pump shaft through a chain 21, sprocket 20, and gear-wheels 19. The vessel 3 is fed from the vessel by another pump.

Abstract: 1371306 Acoustic velocity measurement: ultrasonic couplings WESTINGHOUSE ELECTRIC CORP 29 May 1973 [6 June 1972] 25472/73 Headings H4D and H4J - Apparatus for measuring the relative velocity between a group of probes and a fluid comprises a number of transducer stations each having a cavity in which is disposed a transducer and a coupling medium, the cavity being closed by an acoustic window, an acoustic signal path between a first and second of the stations being at a first angle with respect to the acoustic window of the first station and at a second, different. angle with respect to the acoustic window of the second station, the windows being of different materials. The apparatus of the described embodiment comprise housings (15), (16) (17) (Figs. 1, 2, not shown) in a triangular array and being connected to circuitry (20) for deriving the speed of a ship (10). A further housing 15, Fig. 6A, supports a transducer 30, coupling medium 57 and window 55. The coupling medium may be water or a gel, e.g. agar-agar mixed with water. The aft housing 17 also comprises a transducer 30, coupling medium 57 and a window 63. This housing supports an additional transducer, medium and window assembly for co-operation with third housing (16) but are not shown. The angles of incidence # 1 , # 2  of sound beam S are different for the two housings due to their orientation. It is stated that for correct operation of the apparatus the angles of incidence have to be at least 5 degrees removed from the critical angle for each window and to ensure that this is so, different materials are used for the windows, e.g. polymerized methyl methacrylate for window 55 and acrylonitrile butadienestyrene for window 63. If different materials were not used angles # 1 , # 2  would be within or very close to the range of variation of critical angle of a particular window resulting in both longitudinal and shear waves being produced. As these travel with different speeds in each window wave interference could result and produce degradation of the signal.

In a receiver for the reception of predetermined radio frequencies which are separated by constant intervals and spread over a wide frequency band, the received radio frequency is changed into a fixed intermediate frequency through two frequency changing operations by means of crystal-controlled local oscillators. As shown, the radio frequencies are amplified at 11 and mixed at 13 with oscillations supplied by a first local oscillator 12 which is arranged as a harmonic generator and selector to provide a selected one of a plurality of equally-spaced frequencies. The output from the mixer 12 is supplied to a filter 14 and the resulting first intermediate frequency oscillations are mixed at 15 with oscillations supplied by a second local oscillator 16 which provides a selected one of a plurality of equally-spaced frequencies. The output from the mixer 15 provides a second fixed intermediate frequency which is selected by a filter 17 and supplies an amplifier 18.

Abstract: 722,702. Gas turbine plant. LUCAS (INDUSTRIES), Ltd., J. Jan. 1, 1952 [Oct. 26, 1950], No. 26098/50. Class 110 (3). [Also in Group XXIX] In a liquid fuel system for jet propulsion and other gas turbine engines used on aircraft in which fuel supplied by a pump a in excess of the burner requirements is spilled from the system at any convenient point between a throttle e and the burner b, the ratio of the spillage to the fuel supply to the burner is arranged to increase with increasing altitude and is independent of the position of the throttle. Fig. 1 shows the invention applied to a system with constant pressure burners b supplied through a valve bl by a pipe d containing a manually-adjustable throttle e. A spill pipe t leading back to the pump suction s has a restricted orifice u. As the pressure between the throttle and the burners is constant, the pressure drop across the orifice u and therefore the spill flow therethrough is constant. The flow through the pipe d is regulated by applying the pressure drop across the throttle e to a spring-loaded piston g operating a lever h which carries a leak-off valve i controlling a servo-piston n. The lever h is also loaded by opposed elastic capsules k, m, one k being evacuated and the other m being open to the atmosphere. The opposite sides of the spring-loaded servo-piston n are connected by a restricted orifice p. As shown, the servopiston n adjusts the fuel supply by adjusting the swash-plate of the pump, as described in Specification 577,016, [Group XXIX]. In a modification, however, it adjusts a by-pass valve associated with the pump. In a further modification using swirl type burners, the flow in the spill pipe t is kept constant by a throttle arranged downstream of the restricted orifice u and adjusted in accordance with the pressure drop across it.

Abstract: 1391006 Hydraulic axial piston motors LINDE AG 5 June 1972 [19 June 1971]  26104/72 Heading F1A An hydraulic axial piston motor comprises a cylinder barrel 5 rotatably mounted on a stationary shaft 2 including an integral swash-plate 10, epicyclic gearing 20, 21, 22 between the barrel 5 and motor housing serving to rotate a member 18 which partly surrounds the barrel 5 and transmits torque to an output shaft 16. Toothing 22 on the periphery of barrel 5 engage epicyclic planetary gears 20 which in turn mesh with internal toothing 21 on the motor housing. Thus rotation of barrel 5 causes rotation of gears 20 and hence of member 18. Brake plates 24, 25 attached to the barrel 5 and housing part 12 are operated by single acting pistons 28. In other embodiments, rollers engaging undulatory cam surfaces on the barrel are employed, Figs. 2, 4 (not shown) it being possible to employ two sets of rollers having different gear ratios so that only one is operational at any time, Fig. 5 (not shown). Alternatively, the barrel can be eccentrically mounted and have toothing which engages with internal toothing on both the housing and the member 18, the number of teeth on these latter being different to cause relative rotation between them, Fig. 6 (not shown). A double level gear on barrel 5 can engage level gears on the housing and member 18, Fig. 7 (not shown). The swash-plate can be fixed or variably inclined.
