Abstract: 1,033,929. Fuel cells. UNITED AIRCRAFT CORPORATION. Nov. 30, 1962 [Nov. 30, 1961], No. 45350/62. Heading H1B. The electrolyte level of a fuel cell 2 is controlled by a bellows 30 which operate a by-pass valve 28 diverting more or less of the exhaust gases including excess hydrogen from a radiator 16 in which water is condensed out.

Abstract: 1429828 Ultrasonic transducers NIPPON TOKUSHU TOGYO KK 5 Oct 1973 46742/73 Heading H4J An ultrasonic device A (Fig. 1) comprises a metal ring 1 having an outer circumference and an inner circumference and at least one ultrasonic electromechanical transducer E fixed on the outer circumference of the ring 1. In use the ring generates ultrasonic vibrations in the medium within its inner circumference. The transducer is effective in operation to cause the ring to resonate at a frequency corresponding to a wavelength given by t = (n#)/2, where t is the effective thickness of the ring, # is the wavelength of resonant waves in the ring and n is an integer. The device may be used for the continuous ultrasonic mixing or emulsifying of liquids in a pipe or tube. Other applications are ultrasonic chemical acceleration, ultrasonic diffusion, ultrasonic suspension and ultrasonic destruction. The outer circumference is machined into a regular sixteen-sided polygon and on each face 2 is fixed a piezoelectric transducer E (e.g. lead zirconate-lead titanate) which vibrates in a thickness mode in response to a frequency of at least 15 kHz (preferably 400 kHz) produced by an oscillator (not shown). The frequency is such that the ring resonates. Several such devices A may be connected by tubes 4 (Fig. 2) in the longitudinal or axial direction thereof. Each rim of tube 4 between the devices A is embedded in a groove 3 cut circularly along side faces of the metal ring 1. Grooves 3 are cut at the nodal region of radial vibration of ring 1 at the operating frequency. A flange 5 circularly supports the outer circumference of each tube 4 at the nodal point of longitudinal vibration at the operating frequency. Liquids flowing through the tubes 4 and the rings 1 are subjected to vibrational energy as they pass along the tubes 4. Flanges 5 are preferably bolted to vibration dampers.

Abstract: 1305267 Lubricating GENERAL ELECTRIC CO 2 Oct 1970 [2 Jan 1970] 47002/70 Heading F2A [Also in Division F1] Lubricant is supplied to a gas turbine engine, which has two rotor shafts 10 and 12, by pumps driven by the shafts. Lubricant is pumped from an external source by a pump 22 connected to the high pressure rotor 12 and passes into a chamber 34 which contains gear-wheels 60, 62 driven by the low pressure rotor 10. From the chamber 34 lubricant passes via duct 66 to the bearings 20 and thence to the sump cavity 14. Lubricant is scavenged from the sump via duct 26 which leads to a chamber 30. A vane pump 40 driven by the low pressure rotor 10 forces the lubricant from chamber 30 to chamber 32 from which it passes to the use points in the engine. The sizes of the chamber 34 and the gears 60, 62 are so arranged that the amount of lubricant discharged to the sump via duct 66 is a function of the speed of rotation of the low pressure rotor and hence in fixed relation with the amount of lubricant scavenged from the sump.
