Title: Balancing apparatus for rotating bodies and method of producing frequency stable phase delay
IPC: G01M1/28
Filed: 1973-01-26
Abstract: 1422715 Measuring rotary unbalance electrically HUNTER ENG CO 26 Jan 1973 [9 Feb 1972] 3987/73 Heading G1N [Also in Division H3] Apparatus for detecting the position of rotary unbalance in a rotatable body e.g. a vehicle wheel 10 comprises a spinner device (17), Fig. 2 (not shown) capable of rotating the body at a speed higher than its critical speed, a pick-up device 19 including a voltage generator which produces a sinewave voltage 22 proportional to the vertical vibration velocity of the wheel and its suspension system which voltage is fed through limiter 25 and amplifier 26 to produce a squarewave 27 synchronized with the sinewave; the squarewave being fed to a network including a constant current source 29, a constant current drain 31 and a capacitor 32, arranged to respond to negative-going zero-crossings of the squarewave to charge the capacitor from the constant current source and to respond to positive-going zerocrossings of the squarewave to discharge the capacitor at a rate twice the charge rate, see waveform 43A in Fig. 3A; a comparator 38 connected to the capacitor and to a reference voltage source 40 and arranged when the capacitor is discharged to the reference voltage to clamp the capacitor voltage at that level and to trigger a flash tube device 42 to illuminate a reference index e.g. a valve stem (44) on the wheel whereby an operator may establish by eye the angular position of the stem when meter 43 connected to pick-up 19 is indicating that the wheel is vibrating at its critical resonant frequency. The wheel is then halted and rotated so that the valve stem is at the observed position at resonance when, since the flash tube has been triggered at the peak of the velocity representative wave 22 (see Fig. 3A), the unbalance mass is at the lowermost wheel position so the operator attaches a counterbalancing weight, of a magnitude determined by the meter reading, to the topmost disposition of the wheel rim. In an alternative method of use the operator adjusts the speed of the driven wheels of the vehicle to achieve a sensation of maximum vibration transmitted through the vehicle body, the network in this case being set to give 135 degrees phase lead.

Filed: 1921-02-03
Abstract: 177,927. Smith, L. M. Feb. 3, 1921. Nut preparations.-An imitation milk, which may be concentrated or dried like cows milk, is prepared from coco-nuts by extracting the endosperm with the water of the coco-nut. For this purpose the endosperm of fresh coco-nuts, preferably at the stage of ripeness at which the liquid is barely perceptible on shaking, or clean copra, is ground up with the water of the coconut, or it may be comminuted and the water afterwards added.

Abstract: 813,829. Soldering. GENERAL ELECTRIC CO. Feb. 10, 1956, No. 4256/56. Drawings to Specification. Class 83 (4). [Also in Group XXXVI] Two members, at least one of which is ceramic, are bonded together by forming between their adjacent surfaces an alloy including titanium, zirconium, hafnium or thorium, the alloy being produced by placing in contact with the members at least one layer of at least one component metal of the alloy, heating to a temperature above the eutectic melting point of the alloy and cooling to solidify the alloy. The alloying metal may be copper, nickel, molybdenum, platinum, chromium, cobalt or iron, and the alloy should be one which liquefies at a temperature below the melting point of any of the alloyed metals and below the softening point of the ceramic.

Filed: 1943-04-01
Abstract: 587,771. Lubricating systems. POWER JETS, Ltd., and FEILDEN, G. B. R. April 1, 1943, No. 5265. [Class 12 (iii)] In a multiple-delivery lubricating system having a continuous circulation of oil in' a main circuit offering substantial viscous resistance to flow, the branch lines have flowrestricting means offering proportional viscous resistance whereby the delivery; is independent of the viscosity of the oil. The flow-restricting means comprises a helical passage formed by a screw thread fitting a cylinder, the main flow passing through or around the restrictor so that its temperature controls that of the branch flow. As applied to a gas-turbine aero-engine, Fig. 1, the turbine 2 and impeller 1 have a common shaft with front and rear bearings 3, 4 and a gear-box 5 for auxiliary drives such as the oil gear pump 6. This pump receives oil from a tank 7 and delivers it by pipes 9, 9A through a filter 10 and check valve 11 with pressure gauge 9B to the bearings 3, 4 and tank 7. Tappings from pipe 9 may supply other parts such as the gear-box. A scavenge pump embodied in unit 6 may return the oil from sumps by pipes 12, 12A, 13 to the tank. Each restrictor, Fig. 3, comprises a cylindrical body 30 carrying a plug 31 with square threads and an outlet union 32. The plug has an inlet baffle 34, to create a turbulence in the main flow oil, and radial ports 35 leading past the screw thread to the outlet. The outlet may consist of drilled bores leading to a spout or nozzle from which the air is sprayed by a transverse external air jet from a nozzle supplied by air under pressure preferably tapped from the engine blower. In a modification, the outflow pipe ends at the gear-box at atmospheric pressure and the scavenge pump returns the oil to the tank. According to the Provisional Specification, the flow-restricting means may consist of a tubular wire gauze filter, one end being held and the other end rotated slightly to alter the bias of the gauge weave and so vary the size of the aperture.
