Patent GB-922928-A (GB)
Title: Improvements in bearing torque test instrument
Inventor: BARNARD THEODORE PAUL
IPC: G01M13/04
Filed: 1961-01-30
Abstract: 922,928. Measuring electrically. MINIATURE PRECISION BEARING Inc. Jan. 30, 1961, No. 3442/61. Class 40 (1). [Also in Group XIX] Apparatus for testing ball bearings comprises means for spinning the outer race and measuring the torque required to prevent the inner race from rotating. As shown (Fig. 1), a test bearing 30 has its outer race driven by motor 21 through rotor 15 and adapter 32, the inner race being coupled via adapter 36 to a shaft 33 which carries an angular rotation transducer 50 and a torque generator 51, each comprising a fourpole stator 58, 59 and an unwound two-pole rotor 52, 53 (Fig. 4). Each of the four poles of the stator 58 of the transducer 50 carries a first winding which are connected in series to an A.C. supply A, and a second set of seriesconnected windings which are connected to output terminals B, the direction of winding being such that with the rotor 52 located symmetrically with respect to the stator poles, as shown, the output signal at B is zero, but displacement of rotor 52 produces an output signal whose magnitude and phase sense is indicative of the magnitude and direction of rotation of the rotor. The torque generator 51 is similarly constructed and wound, but the exciting windings are fed with a constant D.C. voltage, and the other windings are fed with the output signal from transducer 50, after conversion to an equivalent D.C. value of correct polarity. Thus, the inner race of test bearing 30 rotates shaft 33 and coupled rotors 52, 53, the output signal from transducer 50 being rectified and fed into torque generator 51 to bring the shaft to rest at a position where the two torques are equal and opposite, and are measured by the output signal from transducer 50. This signal may be fed through a variable filter to enable the faults in the test bearing 30 to be analysed. The axial loading on the bearing may be increased by the addition of weights 42, and hunting is mechanically reduced by a fixed cup 25 containing a viscous damping fluid, and a cylinder 26 attached to the shaft 33 and located with small clearance from the inner wall 27 of the cup. In another embodiment (Fig. 7), the counter-torque to shaft 101 driven by the inner race of test bearing 30 is produced by a torsion wire 100 fixed at its lower end to a diaphragm 106, the angular displacement being measured by transducer 50. The axial loading is controlled by varying the air pressure on diaphragm 106.

Title: Improvements in or relating to method and apparatus for handling finely divided solids
IPC: B01J8/14
Filed: 1954-07-28
Abstract: <PICT:0788294/III/1> Fluidized solids are transferred from zone 202 to zone 200 by withdrawing the solids through column 222 to a sealing zone 228, from which the solids pass through pipe 234 to zone 200; the point of withdrawal of solids from sealing zone 228 is above the discharge level from the column 222 which has an extension 327, preferably at least half the depth of the sealing zone; gas is introduced at 238 into line 234 to reduce the density of the solids and so control the rate of flow.  Fluidizing gas is also introduced at 224 and 232.  Solids are returned from zone 200 to zone 202 in a similar manner through standpipe 248 and sealing zone 260.  In a catalytic cracking process, hydrocarbon is introduced at 266 or 268 or both and contacts catalyst, e.g. silica-alumina, in zone 202 at 850-950 DEG  F.  The catalyst passes through orifices 214 to zone 216 where it is stripped by gas entering at 218.  Regeneration with air takes place in zone 200 at 1000-1200 DEG  F.  Zones 200 and 202 are provided with cyclone separators, the solid discharges from which may comprise lift pots 154, 1541 as described in Specification 788,293. Reference is also made to the use of the apparatus for hydroforming and coking.

Title: Improvements in or relating to electrical signalling systems
IPC: B66B19/06
Filed: 1938-02-03
Abstract: 510,612. Winding-apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and ERICKSON, A. E. Feb. 3, 1938, No. 3467. Drawings to Specification. [Class 78 (v)] [Also in Group XXXVIII] In an electrical signalling system for controlling the winding operations in mine shafts, a normally inoperative mechanism for limiting the speed of operation of the winding engine throughout a wind is automatically brought into operation in response to the transmission of a signal, the "men" signal, indicating that caution is necessary. Alternatvely, an audible or visual signal may be given until a mechanism for limiting the speed of operation has been brought into action. In a further modification, the starting of the winding engine in response to the "men" signal is prevented unless the speed-limiting mechanism has been made effective. The alarm circuit may be opened when the control lever is moved from the " coal " to the " men " position and in the last modification the alarm device is replaced by an electric lock on the starting lever of the engine.

Title: Improvements in rubber threads and methods of making the same
Filed: 1936-02-13
Abstract: 470,403. Rubber threads; cutting rubber. EASTHAMPTON RUBBER THREAD CO. Feb. 13, 1936, No. 4349. Convention date, July 13, 1935. [Class 70] An article comprising rubber threads adhesively but releasably bonded to each other in parallel relationship to form a tape one thread thick and of great width relatively to its thickness is characterized in that the threads are vulcanized and the bonding of the threads is controlled so that the assembly can be readily and cleanly separated by force into its component threads. The threads may be bonded by the inherent adhesiveness of the rubber, the adhesion being controlled by dusting talc between the threads. The following methods are used : (1) An unvulcanized sheet is wound upon a drum, the sheet being dusted with talc during the winding operation, cut from the drum, flattened, cut to the shape of an annulus 2, vulcanized, and secured by shellac to an unvulcanized sheet of rubber 4 forming the facing of a turntable 3. The table rotates slowly and tapes are cut from the annulus by a moving, swiftly-rotating, circular, inclined knife 6. (2) The annulus is cut by a curved knife, beginning at the outer periphery. (3) Superposed rubber cylinders dusted with talc are wound on a drum and tapes are cut in situ by a rotating knife. (4) Streams of latex are deposited in side-by-side juxtaposition on an endless belt which passes through driers. To lessen the degree of adhesion of the threads, talc may be dusted thereon. (5) Latex is extruded into a coagulating bath and the threads thus produced brought together at the end of the bath in a tape or rope-like form; talc may be used. The tape produced by these methods may be easily separated into threads, e.g. by merely peeling off or by subjecting parts of the tape to tension or by passing the tape, under tension, through a comb, whence the threads are led direct to a machine for weaving or braiding. Specifications 424,744, 457,689 ; and 470,448, [Group IX], are referred to.
