Patent GB-259888-A (GB)
Abstract: 259,888. Gledhill, A. H. July 23, 1926. Factory and like time-recorders, autographic.-In apparatus wherein the operative's signature is written on a record-strip between two time impressions, the main operating shaft is given a complete revolution in intermittent periods by means of the to-and-fro movement of a reciprocating hand lever. The hand lever A, as shown in Fig. 2, is mounted on a shaft a having a toothed sector a' in gear with a pinion b loose on the main operating shaft B but operatively connected thereto by means of a oneway clutch b<1>, b<2>, Fig. 3, and a spring b<3>. On the downward movement of the lever A the shaft B is rotated until a pin b<6> on the disc b<5> carried bv the shaft B engages an abutment a<4> on the sector a<1>. The lever A is returned by spring means, the shaft B remaining stationary by the slipping of the clutch until toward the termination of the movement an abutment a<3> on the lever engages a roller b<4> on the disc b<5> and completes the movement of the main shaft in the clockwise direction. During the initial downward movement of the lever A a cam d<1>, Fig. 1, through a pawl carrying arm d<2> slightly advances the record-strip D and a cam c. through contact with a roller c<1> retracts and releases the impression hammer C. At the same time a pin c<3> on the cam c rocks a lever c<4> so as to permit a pawl c<6> to engage a ratchet wheel c<7> on the minute type wheel for the purpose of aligning the type. During the continued downward movement of the lever the cam d<4> completes the feeding of the record-strip and a cam e through a lever e<1> operates the shutter E to open the writing aperture. Near the end of the return movement of the handle the shutter is closed and a portion c<12> of the cam c effects a second operation of the impression hammer.

Title: Improvements in electrical apparatus for the elimination of aperiodic disturbances
IPC: H04B1/12
Filed: 1924-10-31
Abstract: 226,784. Regnauld de Bellescize, H. J. J. M. de. Dec. 28, 1923, [Convention date]. Atmospherics and undesired signals, eliminating and limiting.-Relates to means for eliminating electrical disturbances superposed on sinusoidal vibration. As shown in Fig. 1, the complex current from an output circuit A-A is fed to a thermionic amplifier D through a differential arrangement comprising an iron-cored transformer T<1> and an air-cored transformer T<2>. The hysteresis of the iron core of the transformer T<1> acts anologously to friction upon the relatively feeble sinusoidal vibrations, practically damping them out, but passing the more intense disturbances. On the other hand the transformer T<2> passes integrally all the currents of which the circuit A-A is the seat. The two outputs are opposed on the grid of the amplifier the sinusoidal frequency being finally selected in the tuned circuit R. Fig. 3 shows a modified arrangement. in which two pairs of polarized electromagnets B<1>, B<2> are used. The armature F<1> is subjected to the action of a damping resistance caused by the friction of the part H rubbing on the part G, thus cutting-out the relatively feeble sinusoidal vibrations. The two outputs are opposed as before on the grid of the amplifier D.

Abstract: 745,854. Variable speed gearing. INDUSTRIAKTIEBOLAGET LUXOR. Sept. 22, 1953 [Sept. 29, 1952], No. 26114/53. Class 80(2) A speed governor, between a driving shaft 2 and, e.g., the turntable (not shown) of a gramophone, comprises a, variable ratio friction gear 5, 10 and a centrifugal device 3 on the driving shaft controlling the gear ratio to give a constant speed to a driven shaft 11. The friction gear consists of a roller 5 of generally conical shape engaging a disc 10. Weights 3, on levers 4, 6 pivoted on the roller and connected by links 7 to a disc 8 fast on the driving shaft, fly out under the action of centrifugal force to move the roller axially on the driving shaft, against the force of a spring 9, and vary the ratio. The generatrix of the roller 5 is determined empirically from the characteristics of the centrifugal device so that the disc 10 is always driven at a constant speed. The roller 5 is also so shaped that it does not engage the disc 10 when the device is at rest. In a modified form, a driving disc is moved axially with respect to a driven roller. Specification 328,717 [Class 40(ii)] is referred to.

Title: An improved method of mounting and driving centrifugal separating apparatus
IPC: B04B9/12
Filed: 1925-10-20
Abstract: 269,218. Grimble, F., Caird. M. N., and Coombs, E. Oct. 20, 1925. Driving, suspending, and balancing. - The bowl of a centrifugal separator contains liner discs and is connected to the upper end of the main shaft so that it can oscillate to a limited extent while the shock is absorbed by the intermediate and footstep bearings. The upper end 6 of the shaft 7 is partly spherical and supports the bowl through the central socket 2 and the bearing block 5. A ring 9 is secured to the socket 2 to limit the oscillation of the drum, and a driving cotter pin 10 is passed through the shaft within the socket. The intermediate bearing consists of a floating bush 11 held by spring pressed plungers 16 arranged in the housing 12. The spherical surface 18 at the lower end of the shaft 7 rests in a correspondingly recessed bearing block 19, spring-supported in a housing 20 connected to the shaft by some form of universal coupling 22. The block 19 thus receives the axial thrust of the shaft 7 but allows it to move at small angles in relation to the block. A worm shaft 24 enters the shank 23 of the housing 20 and is supported in roller bearings 25, 26. This shaft is operated from a motor 30 through a centrifugal clutch 35 and toothed and worm gearing. The same mechanism drives the lubricating-oil pump 36 and a pump 38 which can be used to supply the mixture to the bowl or to empty vessels adapted to collect the separated liquids. A brake 37 operated by hand or hydraulically or electromagnetically may be provided.

Title: Radiation fuel gauge
Inventor: HOWARD DONALD FRANKLIN
IPC: G01F23/288
Filed: 1959-07-31
Abstract: 885,102. Photo-electric measuring systems. NORTH AMERICAN AVIATION Inc. July 31, 1959, No. 26327/59. Class 40(3). The attenuation of gamma rays in passing through a fuel tank is utilized to provide a measurement of the mass of fuel in the tank. When the tank is irregularly shaped (e.g. as in an aircraft) compensation is provided for the departure from .a -  linear relationship between the attenuation of the gamma rays and variation of the quantity of fuel in the tank. Fig. 1 shows the application of the invention to measuring the mass of fuel in a plu ra li t y of irregularly shaped tanks 1 . . . 5 in an aircraft, each tank having a source of gamma radiation 6 (e.g. Cobalt 60, Cesium 137 or radium &c.) disposed under it and a radiation detector 7 comprising a scintillation crystal 8 (Fig. 2) optically coupled to a photo-electric device 9 positioned above each tank. The output signals from each detector are then converted into D.C. signals in a known rate meter device and supplied to a servo system comprising a pair of ganged potentiometers 19 driven by the motor of the servo system, the first potentiometer having a linear law and supplying the error nullifying voltage back to the input of the servo amplifier and the second potentiometer, having a law determined by the geometry of the particular tank with which it is concerned, and supplying a voltage, linearly .related to the mass of fuel in the tank, to an indicator 20. Fig. 3 shows the arrangement employed for measuring the total mass of fuel in all five tanks of -the aircraft. As shown, the outputs of the rate meters 36 . . . 40 associated with the respective tanks are supplied sequentially (under the control of a step motor 52) to the input of -the servo amplifier 55 the motor 54 of which -drives (via a clutch 53 controlled by a step motor 52) the shaft of the appropriate one of pairs of ganged potentiometers 56 . . . 60. The error nullifying signals for each measurement are then derived from the (linear law) potentiometers 61 . . . 65 and fed back to the input of the servo amplifier via resistors 78 . . . 82 whilst signals linearly related to the mass of fuel in each tank are derived from potentiometers 66 . . . 70 which have laws determined by the geometry of the associated tank. The latter signals are then combined in a summing device 76 and fed to an indicator 77. Since the mass absorption coefficient of gamma rays is approximately constant variations in fuel density due to temperature changes do not affect the measurement. By employing a plurality of radiation sources disposed about each tank the output of the rate meters varies in an approximately linear manner with variation in quantity of fuel (Figs. 6 and 7, not shown) and such outputs may be supplied directly to the summing device to obtain an approximate measure of the fluid content.

Abstract: 1,017,537. Welding by pressure. GENERAL MOTORS CORPORATION. July 4, 1963 [July 31, 1962], No. 26511/63. Heading B3R. [Also in Division B5] Members are welded together by clamping the members between the end portions of a pair of columns, driving a mass or masses in an orbital path or paths and coupling the mass or masses in vibration transmitting relationship with one of the columns to cause the column to vibrate at its resonant frequency. Two metal sheets 11, Fig. 1 (not shown), are positioned between an anvil 6 connected to an air-operated piston device 8 fixed to a rigid cross-beam 10 and a nickel alloy bearing portion 27 on the upper and smaller cylindrical column 20 of a vibration transmitting member 2 having a lower and larger cylindrical column 18. The column 20 constituting the vibratory portion of the member 2 has a laterally extending integral arm 22 carrying a vibrator 12 in a circular opening 24, Fig. 3 (not shown), the vibrator being actuated by compressed air supplied through a valve 13 to passages 28 and 32 in the column. The vibrator 12 comprises a cylindrical housing 36 closed at opposite ends by apertured discs 38, 40 which define a chamber 42 for a cylindrical roller 44 and the arrangement is such that air flows into an annular chamber 34 around the housing 36, to discharge through tangential orifices in the housing 36 as high-velocity streams impinging on the roller periphery. The roller 5 is driven in an orbital path about the chamber and applies force to the housing, force in directions A and B, Fig. 2 (not shown), twisting the column in opposite directions and forces in directions C and D bending the column. The vibrator is mounted at an antinode on the column and is driven at a frequency equal to the resonant frequency of the column. In another embodiment two vibrators are provided in arms extending from opposite sides of the column and are connected to the central air passage so that both rollers are driven in counterclockwise direction at phase differences of 180 degrees to cancel forces acting along the axis of the support arms and produce pure torsion. The bearing portion may preferably have an annular form to produce a ring weld. In a modification of the last embodiment the two vibrators are connected to the central air passage so that the rollers are driven in opposite directions to eliminate torsional effects and produce only an oscillating movement of the column normal to the axis of the support arms.
