Title: Sedimentation device
IPC: C02F1/00
Filed: 1946-03-25
Abstract: 615,461. Gravity separation apparatus. GENERAL AMERICAN TRANSPORTATION CORPORATION. March 25, 1946, Nos. 9088 and 9089. Convention dates, March 26, 1945 and April 14, 1945. [Classes 46 and 111] Sedimentation apparatus, of the kind in which slowly-moving arms carry scraper blades or the like over the bottom of a setting tank to collect and remove sludge, is characterized in that independent tongue and lifting forces are provided, the scraper-carrying frame being directly and positively lifted in response to an overload condition and being released to sink down to its operating level as the overload condition passes without waiting for a condition of underload, both the lifting and release movements being independent of the rotation of the frame. in the construction shown in Figs. 2 and 4, the scraper frame 52, which is only partly shown and comprises frame members 94, 96, 98 and arms 90 carrying scraper blades, has upwardlyextending arms 48 engaged by spokes 46 on a spider 42. The spider has an internal gear wheel adapted to be driven through retraction gearing from an electric motor 26. The gearing is carried by a support 22 which is mounted on an extension 20 of a pier 14. The extension is slotted and through the slots extend beams 63 which carry a circular track 60. The scraper frame 52 has flanged rollers 58 which run on the track. The beams 63 form part of a frame which is supported by the piston 72 of a hydraulic jack. Pressure fluid is supplied to the cylinder 74 by means of a motor-driven pump and solenoidoperated valve. During the rotation of the scraper frame 52, if an overload is encountered by the scrapers, an electric relay is adapted to close the circuits of the jack pump motor and the solenoid-operated valve whereby the piston and hence the scraper frame are raised. A second relay closes the circuit of an alarm, and a third relay opens the circuit of the motor 26 when the overload is sufficiently serious. Means may be provided for increasing the speed of the motor as the jack is raised. In a modification shown in Figs. 7 and 10, the scraper frame comprises a sheet metal drum 52a which has slots 48a, the edges of which are engaged by wheels 150 carried by a rotatable ring 152. The motor 26 drives through a differential gear two gear trains which transmit movement to the ring 152 through a lower ring 42a and an intermediate ring 176. The ring 42a has at each of two diametrically-opposite positions a roller 180 and a spring- positioned rocker cam 182 on a post 184. The roller 180 and a rocker 182 grip a lug 186 projecting from the ring 176. Similar means are provided for connecting the ring 176 to the ring 152.

IPC: G01F23/24
Filed: 1954-04-01
Abstract: 750,858. Electric indicating systems. GILBERT & BARKER MANUFACTURING CO. April 1, 1954 [April 22, 1953], No. 9558/54. Class 40(1) [Also in Group XXXV] In order to indicate the level of a liquid, a wire 1. Fig. 9, mounted within a belltype shild 9 is suspended vertically with its end just immersed in the liquid. When out of contact with the liquid, wire 1 is arranged to be electrically resonant at the frequency of a high frequency thermionic valve oscillator 46 to which it is coupled through a screened feeder 41 and loops 35 and 50. The oscillator is modulated at 50 c/s by the output of a mains transformer 84 and the voltage developed in wire 1, which decreases owing to the dielectric effect of the liquid as the depth of immersion increases, is demodulated by a crystal diode rectifier 36 the 50 c/c output of which is transmitted through feeder 41 and conductor 68 to a thermionic valve amplifier 73. Amplifier 73 is associated with a 50 c/s supply from a mains transformer 97 so that for a given depth of immersion there is a zero output applied through a transformer 95 to one winding 103 of a two-phase servomotor 5. Deviation in either sense from this depth produces an output from the transformer 97 of the phase sense necessary to run servomotor 5 in the appropriate direction to operate a level indicator while moving wire 1 to maintain a constant depth of immersion. A weighted pulley tensioning device (Fig. 1, not shown) is arranged to take up any slack in feeder 41. The end of wire 1 may be bent to increase sensitivity and if the liquid is conductive the tip of wire 1 is insulated to prevent conduction effects.

Title: Infinitely variable speed gear
IPC: F16H29/06
Filed: 1923-08-13
Abstract: 212,438. Beabey, J. H. Aug. 13, 1923. Variable-speed ratchet gearing comprises an eccentric sheave A adapted to slide radially in a groove in a disc C splined so as to turn with a driving-shaft H. The throw of this driving eccentric is varied by sliding a head D in an inclined slot in the sheave, the head D being mounted on a through sleeve operated from a lever W. The eccentric strap K is steadied bv an arm N which carries a pin Q reciprocating in a slot in a pillar P upon an inner revoluble casing O. The casing 0 is normally kept from turning by a locking-device X engaging teeth upon it. Separate arms S extending radially carry spring pawls S<1> engaging internal ratchet teeth in a driven disc or member G. Each arm S has a sliding connection R with the strap K. As the throw of the eccentric A increases, the swing of the arms S and the speed of the disc G increase also. When the speed of the disc G approaches that of the eccentric A, clutch teeth E on the head D engage a clutch head F projecting from the disc G, teeth L. on the strap K engage teeth M on the casing O, and so effect a solid drive. This is rendered possible by the simultaneous withdrawal of the sliding locking-device X. A fixed casing Z, Fig. 4, surrounds the whole with external driving and driven sprockets T, G<1>. The roof of the casing Z is ribbed internally as shown so that oil splashed upon it will drop back on the gearing and not run down the walls of the casing.
