Title: Improvements relating to combined weighing and counting scales
IPC: G01G19/42
Filed: 1945-12-17
Abstract: 615,538. Counting scales. FITZPATRICK. H. J. (Maatschappij van Berkel's Patent N. V.). Dec. 17, 1945, No. 34054. [Class 143] A combined weighing and counting scale has counting mechanism which is movable to effect disengagement thereof from the weighing mechanism or effect release thereof from the inoperative position and re-engagement thereof with the weighing mechanism, manual control means adapted, on a single movement thereof to effect said movement of the counting mechanism, and means for positively supporting the counting mechanism against displacement from the inoperative position. The scale may be housed in a casing. In Fig. 1, which shows the counting mechanism in operative position, a tape 1 leads upwards from the weighing platform and co-operates with segments &c., not shown, in the usual manner. A rod 5 extending upwards from the lever system in the base is connected to tarebeam 8 through a knife-edge, the tarebeam itself being pivoted on a knife-edge. A counting lever 20 which is fulcrummed on a bracket 24, carries the counting pan 22 at one end and is connected at the other end through knife-edges to a projection on the tare-beam 8. A counterweight 15 is also suspended from the other end of the counting lever. The bracket 24 is rigidly secured to a lever 28 which is pivoted at one end 27 to the frame, and a manual lever 31 also pivoted on the frame is connected to the other end of lever 28 by a freely pivoted link 29 and a link 32 which is rigidly connected to lever 31. A screw adjustable stop 25 is provided on the lower end of bracket 24 for adjusting its setting relatively to links 29 and 32. A movement of lever 31 anticlockwise depresses lever 28, bracket 24, and counting lever 20, thus removing tension between the counting lever and the tare-beam, and permitting the counterweight 15 to rest on a seat.

Title: Improvements in and relating to magnetic direction finders
Filed: 1930-11-19
Abstract: 367,426. Discharge tubes. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Tear, J. D. ; 56, Washington Avenue, Schenectady, New York, U.S.A.) Nov. 19, 1930, No. 34844. Convention date, Nov. 19, 1929. [Class 39 (i).] A magnetic direction finder comprises a normally partially energized indicator having a number of windings whereof one portion is normally de-energized and the other normally energized, together with an electron discharge device which is stabilized in a horizontal plane and swings from a pre-set position to complete the energization of the indicator. In one arrangement the discharge tube is provided with a collar 13 pivoted at 14 in a frame 11 rotatable about a vertical axis 12, a pendulum 15 being secured to the collar. The frame 11 is orientated with respect to a compass card 20 and when applied to aircraft the discharge tube is pre-set with its longitudinal axis at right-angles to the magnetic meridian. The filament 22 is heated through a transformer 26 which is supplied from a source 23 generated, for example, by a wind-driven alternator. The anode battery 28 is connected to the mid-point of the filament transformer secondary and energizes one phase winding 31 of an indicator or motor 30, the other phase winding 32 being energized from the source 23. A polarizing field winding 38 for the discharge tube is also energized from the source 23, a series resistance 39 being provided which normally permits slight variations of anode current at positive and negative maxima of the polarizing field. The winding 38 extends the whole length of the tube. Phase windings 31, 32 are tuned to the frequency of the supply 23 and since the winding 31 normally receives the anode current pulsations at twice that frequency, no turning movement is exerted on the motor. When the craft deviates from the magnetic meridian in either direction, a component of the earth's field is effective to produce a current of complex wave form at the supply frequency and with suitable dephasing a torque is exerted by the motor 30 to operate a counter 47. The motor 30 may be replaced by one having its armature biased into a central or neutral position, or a moving-coil dynamometer may be employed as the indicator. In a modification, the battery 28 is replaced by another generator supplying current at twice the frequency of the generator connected to the source 23, the two generators being mounted on the same shaft and being wind-driven.

Title: Improvements relating to gear profile testing machines
IPC: G01B5/20
Filed: 1934-12-04
Abstract: 437,770. Testing toothed gears. MICHIGAN TOOL Co., 7171, Six Mile Road, Detroit, Michigan, U.S.A. Dec. 4, 1934, No. 34860. Convention date, Dec. 4, 1933. [Class 106 (ii)] The machine is provided with work-holding means, gauging means movable rectilinearly tangentially to the base-circle or like datum of the work, a fixed ratio train of interconnection between the work and the gauging means, and an angularly adjustable transmitting member for compensating for difference ratios between the size of the work and the movements of the gauging means. The gear 72 is supported on a shaft 71 between an upper axially adjustable centre 23 and a lower rotatable chuck 67 journalled in the framework. The chuck can be freed from its spindle, the lower end of which carries an arcuate friction element 22 against which bears a straight bar 21 held against the element by eccentrically adjustable rollers 64. This bar moves solidly with a sine bar 18 on a carriage 15 supported on ball bearings in V-tracks 13 on the machine body, the carriage being moved by turning a hand wheel 14 having a calibrated index. The sine bar 18 is a straight bar mounted for angular adjustment on the carriage to an extent determined by the ratio between the base circle of the gear under test and the diameter of the arc of the friction element 22. Upon tracks similar to but at right angles to the carriage tracks is mounted an indicator carriage 24 acted upon by a counterpoise which holds the carriage so that a nose 26 on the latter engages the sine bar. The carriage has mounted upon it an indicator head vertically adjustable in an upstanding bracket 32 which is transversely movable by a manually-operated threaded spindle 29 upon a sub-carriage 27 longitudinally movable on the carriage engaging the sine bar. The work is set up and the sine bar adjusted angularly. The feeler 32 is then adjusted to contact with the base circle of the gear. Then, when the wheel is turned to move the sine bar carriage a given amount, the gear is rotated through a required angle and the feeler is correspondingly moved and should, if the gear is correct, still contact with the same pressure. The gauges 55 on the gauging head indicate departure from this constant pressure.

[Also in Division F4] A disposable aluminium cylinder 1 containing e.g. liquefied propane, has an opening, defined by a bead 2 and closed by a crimped cup 3 with a flange 5 sealed by a gasket or an elastic compound to the bead. The centre of the cup embodies a discharge opening 9 around which is held an elastic seat 10 for a spring-closed valve 14 depensing from the cup. A synthetic plastic bush upstands from the cup and upon screwing a cork thereto a tubular portion of the latter unseats the valve 14 and sealingly abuts the seat 10. The cup 3 is additionally provided with both a depending spring-loaded reliefvalve 19 seating on a rubber gasket 22, and a frangible rubber closure 20 which ruptures at a pressure greater than that at which the relief valve is adjusted to open. The latter has a small discharge opening so that a slow rate or pressure relief is realised.
