Title: Improvements in or relating to bobbin holders for spinning frames and the like
IPC: D01H1/18
Filed: 1931-05-20
Abstract: 369,792. Supporting creel bobbins in spinning-frames. ECLIPSE TEXTILE DEVICES, Inc., Elmira Heights, New York, U.S.A. May 20, 1931, No. 14875. Convention date, May 20, 1930. [Class 120 (ii).] A bobbin support for the creels of spinning and like frame includes fixed and movable parts connected by a ball bearing and drag means slightly to increase the normal frictional resistance in the ball bearing to prevent overrunning of a bobbin carried on the support when the draft on the roving is stopped. The bobbin holder comprises a fixed supporting part 10 and rotatable bobbin engaging part 20 connected by a ball bearing 30 one race 31 of which is spherically curved about a centre on the axis of the part 20. Slots 32 are provided in the lower ball race 31, each slot having a width less than the diameter of a bearing ball 33, so that a ball entering a slot falls slightly out of alignment with the other balls in the bearing. The balls are arranged so that when in contact with one another a space is left between two of them, so that normally each ball may rotate freely but when one of them is in a slot the others are in contact with one another and the friction in the bearing is increased. The slots may be equidistantly spaced, the distance between the edge of one slot and the adjacent edge of the next being equal to a multiple of ball diameter plus the clearance space between the balls divided by the number of slots. According to this arrangement a ball enters a slot at substantially regular intervals. If greater drag is required for heavier yarn packages the slots may be arranged so that a plurality of balls fall into slots simultaneously.

Title: Improvements in or relating to alternating current signalling systems
IPC: H04Q1/453
Filed: 1938-05-20
Abstract: 516,114. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and WRIGHT, E. P. G. May 20, 1938, No. 15102. [Class 40 (iv] . In a voice-frequency dialling and signalling system in which the receiver is inoperative until it has received a prolonged voice-frequency " prefix " signal, means are provided :for preventing a succession of impulses of " prefix " frequency from acting cumulatively so as to bring the. receiver to its operative condition. As shown, a relay XY which responds to currents of signal frequency interrupts the circuit of a normally energized slow-to release relay RB and makes that of a slow-to release relay RC. If the energization of XY does not persist for the full duration of an effective prefix signal a circuit is made for RH which holds itself and RB until the line has been quiescent long enoughto release RC. The relay RB, the relapse of which brings the receiver into its operative condition, cannot therefore be released by any number of rapidly recurring impulses if the first one is too short. Relay G responds to voice-frequencies other than the signal-frequency and holds RB when these are present. Specification 489,545 is referred to.

Title: Improvements in or relating to devices for testing time pieces
IPC: G04D7/12
Filed: 1937-06-04
Abstract: 496,666. Testing timepieces. STANDARD TELEPHONES & CABLES, Ltd., REINKEN, L. W., and BREMNER, F. D. H. June 4,1937, No. 15543. [Class 139] A method and apparatus for testing timepieces includes cathode-ray apparatus in which a standard frequency (e.g. master watch or tuning fork oscillator) is impressed on the plates of the cathode-ray tube so as to produce a continuous, substantially circular, image on the screen thereof, the ticks of the test piece are translated into low-frequency electric pulses which are employed to modify visibly the said image, and the behaviour of this modification is used to indicate the rate of error of the test piece. The standard frequency (master watch or tuning fork) generated by the oscillator 1 is passed through amplifier 2, Fig. 1, to one pair of deflecting plates 3 and simultaneously, but 90‹ out of phase, to the second pair of plates 10 through a phase shift device 13. This produces a spot which describes a substantially circular image 6 on the screen 4 of the cathoderay tube 5, Fig. 1A, with a speed depending upon the applied frequency. Owing to persistence of vision or of the screen, this image 6 is continuous. The ticks of the watch 7 being tested are then converted by microphone 8 into electric pulses which, through amplifier 9, transformer 22 and rectifier 14, are used to modulate the spot brilliance at each tick by means of a specialcontrol electrode or electrodes 15 in the cathode-ray tube. If the rate of the watch ticks is an exact submultiple of the reference frequency, the bright or dark spot 11 in image 6 caused by the tick pulses will remain stationary, otherwise the spot 11 will drift left or right according as the watch is gaining or losing. A calibrated scale 12 is provided on the end of the cathode-ray tube. In modifications, (1) the tube has a conical electrode, Fig. 2 (not shown), to produce a radial deflection of the image at each watch tick ; (2) the rectified pulses from the test watch are applied to one of the stages of the standard frequency amplifier, Fig. 3 (not shown), to give the radial deflection ; (3) the output of the watch tick amplifier is applied in series with the H.T. supply for the cathode-ray tube, Fig. 4 (not shown) ; (4) the output mentioned in modification (3) is rectified. In another arrangement, Fig. 6, a local master watch 24 is used to determine the correction to be applied to a standard frequency oscillator which is not of the precision type. Switches 25 and 26 connect this watch 24 and the test watch 7 to the watch tick amplifier 9. This arrangement is applied to any of the previously mentioned constructions, the master watch being used either to adjust an oscillator or to calibrate the drift on the screen. An unlimited number of testing devices at various stations may be connected in parallel, Fig. 7 (not shown), to a central standard frequency generator.
