Patent GB-120685-A (GB)
Title: Improvements in and relating to Clocks.
Inventor: O'LEARY WILLIAM
IPC: G04C3/02
Filed: 1918-02-19
Abstract: 120,685. O'Leary, W. Feb 19, 1918. Escapements; electric clocks.-A clock having a slight gaining rate periodically (once a minute) stops itself and lets fall the impulse lever of an independent correct pendulum. After giving the impulse, the lever puts restarting and resetting mechanism into action. A purely mechanical of an electrical arrangement may be adopted. The impulse lever C, Fig. 3, pivoted at D, is normally at rest with a toe R on the shoulder Q of a lever L pivoted at M, which in turn rests upon the periphery of a disk I on the arbor of the minute wheel. Just before the expiry of the minute, a notch J in the disk comes under the toe N of the lever L, letting it drop and stop the balance G. The shoulder Q is thus cleared from the toe R of the impulse lever, which accordingly falls on the impulse pallet A of the pendulum B (Fig. 5). After giving the impulse, the lever falls farther, and. with its toe W disengages a detent S from a cam H urged by a separate mainspring and train. The cam acting on the arm U of the detent-lever L lifts it off the balance and, acting on the toe V of the impulse-lever C, resets it on the shoulder Q. The flirt K at the notch J prevents the detent-lever falling back into the notch, and the clock re-commences to go. Fig. 5 shows diagrammatically the electrical arrangement. The detent-lever L set free as before by the clock, completes at 3 the circuit of an electro-magnet n, which lets fall the impulse-lever C. This in turn completes at 10 the circuit of resetting electromagnets q and p. Stop mechanisms.-Fig. 4. A balance G to be stopped in a potent position by a detent L is provided with a set of pins P on opposite faces, and the detent has two corresponding one-way fingers ZO.

Abstract: 337,696. Schwob FrÞres et Cie Soc. Anon., and Varaud, A. Jan. 29, 1930. Projectile fuzes.-In delay-action fuzes or in combined time and percussion fuzes, a centrifugal bolt 7 is locked or unlocked by a longitudinally disposed plunger 4 controlled by a radially disposed spindle 2, which can be set from the outside according to the action desired. In a delay-action fuze, when the centrifugal bolt is locked, a shutter 7<c> attached thereto closes a flash passage 8, and compels the flash from a primer 9 to be delayed by burning through a charge 11 before reaching the detonator 10; whereas when the centrifugal bolt is unlocked it withdraws the shutter from the flash passage during flight and the fuze then acts without delay. In a combined time and percussion fuze, the centrifugal bolt locks or unlocks the percussion fuze. The centrifugal bolt 7 is urged inwards by a spring 7<a> which yields to centrifugal force. The plunger 4 is urged forwards by a spring 5 and is pressed back by an eccentric pin 2b on the spindle 2, which is held in place by a cotter screw 3 and can be rotated by a key applied to a notch 2<c> in its head. In one position, it depresses the plunger and thereby locks the centrifugal bolt. In n another position, at 180 from the first, it allows the plunger to rise, thereby releasing the centrifugal bolt.

Filed: 1965-01-25
Abstract: 1,060,921. Tuning indicator circuits; frequency discriminators. PHILCO CORPORATION. Jan. 25, 1965 [Jan. 24, 1964], No. 3248/65. Headings H3A and H3Q. In the F.M. discriminator circuit of a superhet receiver shown, a signal having a doublepeaked frequency characteristic is taken from the primary 12 of the I.F. transformer 10 and is combined with a signal of flat response taken from a secondary winding 32 of the I.F. transformer to produce a single peak output signal for use in operating an indicating device, e.g. meter 50, so as to give a visual indication when the input signal is correctly tuned. The signal from tap 22 of the primary winding is rectified by diode 24 to give a " double peaked " negative-going output at A (Fig. 3, not shown). Similarly, the output from the secondary is rectified by diode 34 to give a positive-going flat response at B. The difference of the outputs A and B appears across resistor 42 at C and varies the bias on transistor 40 so as to adjust the collector current through the meter 50 according to the tuning of the receiver. The transistor 40 can be biased so that signals below a predetermined value do not operate the meter 50. The meter can be replaced by an " electric eye."

Title: Improvements in and relating to electric signalling systems
IPC: H04L15/26
Filed: 1922-02-04
Abstract: 197,366. Lea, N., Ree, J., and Radio- Communication Co., Ltd. Feb. 4, 1922. Selectors, responsive only to particular code signals. A member comprising for example a series of cams moves against a spring towards an alarm position. If incorrect signals are received, the member is returned to its initial position and the alarm is not actuated. The member is set in motion on the receipt of a signal by an electromagnetic clutch co-operating with a constantly revolving shaft. The member is shown in its initial position and comprises cams ZEFJK and UV. When the receiving relay, represented as a key S, closes its front contact, current flows from the terminals Q through the starting contact W to the relay RR which closes the contacts A, B. When the contact A is closed, the clutch P is energized and the cams are coupled to the constantly rotating shaft. The contact B allows the relay RR to remain energized after the contact W is opened. When the hump EF closes the contact L, a circuit is established in parallel with the marking contact M of the relay so that the clutch remains energized if no signal is received. The cam UV ensures that before an alarm can be given, spaces must be signalled during the period that W is closed. When no signal is received, the contact O is closed and the relay SR is energized to close contacts C, D, the latter of which keeps the relay energized. When the contact C is closed, the clutch will not be de-energized by the subsequent opening of the contact G. The contact H on opening de-energizes the relay SR in order to render it ready for the next space. The moving member is made detachable in order that it may be replaced by another member constructed to give an alarm when a different arrangement of signals is received. Instead of the cams, electrical contacts may be provided on the moving member.

Title: Attenuation and gathering of glass filaments
IPC: D02G3/18
Filed: 1949-02-08
Abstract: 666,148. Glass yarns. JAROS, E. P. Feb. 8, 1949 [March 4, 1948], No. 3386/49. Classes 120(i), 120(ii) and 120(iii) Glass filaments 14 are drawn from a furnace 11 through a lubricating chamber 16 by two attenuators 21, 22 and delivered as a sliver 23 to a spinning pot 51. Each attenuator comprises an outer rotor 25 having a circumferential groove 30 in which the filaments are congregated to form the sliver. The sliver is held in the groove by suction, the force being exerted, through apertures 31 extending from the base of the groove through the rotor, from a stationary suction chamber 29 enclosed by the rotor 25 which extends for that part of the circumference of the rotor corresponding to the length of contact of the sliver. As the rotor 25 rotates the apertures 31 successively move over the suction chamber 29 whereby the sliver is drawn into the groove 30. To ensure that the sliver readily leaves the groove 30 as it passes to the next attenuator or to the spinning pot, a pressure chamber 28 is provided at the point of disengagement of the sliver and as the apertures pass from the suction chamber over a partition wall to cover the pressure chamber air pressure urges the sliver from the groove 30. The chambers 28, 29 may be adjustably rotated to vary their positions. As the sliver leaves the second attenuator 22. it is initially drawn by air pressure into a waste collector 62. To ensure continuity of tension when the sliver is transferred to the spinning pot 51, a loop of thread 74 is provided, the bight of which is wound round a 'brake roller 75 with the ends extending along guides 73, through a funnel 53 and into the spinning pot 51. The sliver extends through the loop to the waste collector so that as the pot is rotated and the brake roller released the loop is gradually taken up and draws the sliver into the spinning pot. An automatic cutter for severing the end of the sliver extending into the waste collector is provided and operates upon the sliver, being drawn over an electrical contact 82 to operate the release mechanism for the cutter 86. Simultaneously as the cutter operates the air pressure, on the sliver drawing it into the waste collector is shut off. If desired, this loop tensioning arrangement may be used for the transfer of the sliver from one spinning pot to another.

Filed: 1972-01-25
Abstract: 1389561 Endless conveyers T H MILBOURN 12 April 1973 [25 Jan 1972] 3433/72 Heading B8A A probe 40 is reciprocated in a vertical plane above a pile of potatoes to which others are being fed via conveyers 2, 6. When the pile grows sufficiently for the probe head to touch the top of the pile, a Bowden cable 42 is activated to cause energization of an hydraulic ram (not shown) which causes the conveyer 6 to be pivoted upwardly about the axis of its trailing guide pulley 8. A drive wheel 18 for the reciprocation of the probe 40 is driven by a chain 20 from the lower pulley 14 of the conveyer 6. The wheel 18 carries an axially extending roller 22 which engages a horizontally extending slot in a member 26 which is pivotally mounted at 30 on a parallel linkage formed by the conveyer 6 and a link 52. The probe 40 is pivotally mounted at its end opposite to that of the probe head on a pivot 38 extending from the member 26. At an intermediate position the probe rests on a pin 34 carried by the member 26. The Bowden cable 42 is connected to a member 41 rigid with the probe 40 and at its other end with a snap-action member 46 of a valve 48 which controls the conveyerlifting hydraulic ram. The casing of the Bowden cable is connected between a pin 32 rigid with the member 26. Thus as soon as the probe 40 touches the summit of the heap of potatoes the resultant relative movement between the member 26 and the probe causes activation of the ram. A rack and plunger arrangement 56, 58 causes return of the valve member 46 to its normal position after actuation of the ram.
