Title: Improvements relating to electric master clocks
IPC: G04C3/02
Filed: 1944-06-10
Abstract: 580,456. Electric clocks. GLEDHILL, A. H. June 10, 1944, No. 11153. [Class 139] In an electric master clock the impulse lever A, Fig. 1, is suspended by a link B from a freely rotatable latch plate C that is normally locked in the position shown by means of an abutment c<2> engaging a tooth F on a plate f. The upper end of the plate f is connected by a screw f' to an arm G that can turn about a horizontal centre H and the lower end is forked to embrace the arbor c on which the latch plate C is rotatably fixed. The plate f is lifted by a cam J once per revolution of the count wheel D and the tooth F thereon frees the latch plate C whereupon the impulse lever falls, the roller a thereon passes down the incline E on the projection e and imparts an impulse to the crutch E of the pendulum. The impulse lever on its downward motion causes an electric circuit to close so causing an electric impulse to be sent to each of the secondary clocks and dials in the circuit. The impulse lever is returned to its original position by means of an electromagnet (not shown). An adjustable gathering pawl P operates the count wheel D. If it is desired that the pendulum be given an impulse on every swing then the panel O on an arm N suspended from the arbor H is rotated counter-clockwise until the roller o<1> engages the crutch E whereupon at every swing of the pendulum the arm N' on the lever N lifts the link G and so causes the release of the latch plate C and allowing the impulse lever A to fall. Fig. 2 shows a modified arrangement of latches.

Title: Magnetic tape recorders
IPC: G11B15/18
Filed: 1976-03-19
Abstract: 1511445 Magnetic tape recorder STAAR SA 19 March 1976 [21 March 1975] 11262/76 Heading G5R A support 10 carrying a magnetic recording and playback head 6 and a pinch roller 8 in a tape recorder is movable between a stable operative position, Figs. 2, 2a, in which the head 6 engages the tape and the roller 8 engages a capstan 24, a stable non-operative disengagement position, Figs. 1, 1a (not shown), in which the head 6 and roller 8 are spaced from the tape to allow removal thereof, and a stable non- operative intermediate position, Figs. 3, 3a (not shown), in which the head 6 and roller 8 are spaced from the tape but to a lesser extent than when in the disengagement position. On inserting a cassette into a cassette-type dictation machine in the disengagement state thereof, the cassette engages a lug 21, Fig. 2, on a leaf-spring 18 thereby releasing a lug 16 thereon from a locking engagement with the support 10 whereby spring 12 rotates the support 10 about pivot 13 to said intermediate position, Fig. 3, defined by locking engagement of a lug 28 on support 10 with a stop 26 formed by an edge of an aperture 30 in a lever 32, such movement shifting a control slider 50, via lug 28 and a slider 38, to an intermediate position, Fig. 3a. Slider 50 has a slot 68, Fig. 2a, in which ends 64, 66 of lever 32 and slider 38 respectively engage. Pulling slider 50 downwardly via its knob 52, Fig. 2a, from the intermediate position initially pivots lever 32, while slider 38 is stationary to release stop 26 from lug 28 whereafter, while lever 32 is stationary spring 12 pivots support 10 to the operative position and, via slider 38, drives control slider 50 to its operative position, Fig. 2a, lever 32 being coupled via a rod 44 to close a switch 46 during this change to enable operation of the machine. Pushing slider 50 upwardly from its operative position firstly shifts the machine to its intermediate state, and further upward movement of slider 50 from the intermediate state engages the disengagement state and via means (not shown) coupled to slider 38 ejects the cassette. In the operative state, Fig. 2, a mode selecting control knob 70 is movable linearly between stop O, record I, playback II and rewind III positions. The rewind state can only be maintained as long as knob 70 is manually held as its position III, a spring 86 acting on a slidable plate 84 biasing knob 70 back to the playback position II. Movement of knob 70 to the rewind position III shifts plate 84 and via a ramp 92 thereon and a cam 94 on support 10 pivots the latter to disengage the head 6 from the tape and the pinch roller 8 from capstan 24 but does not pivot support 10 as far as the stable intermediate position from the operative position.

[Also in Division F1] In a rotary-piston engine of the n and n+ 1 lobe type, radial sealing strips 16 . . . 20 slidably lodged in a stationary casing for the piston 1 are periodically fed with lubricating oil through a radial conduit 23 in a lobe 3 of the piston. Oil is supplied to conduit 23 through conduits 24, 25 in a power-output shaft 7 and an eccentric 6 carrying the piston, respectively, conduit 25 being located in the eccentric such that oil flows, through conduit 23 whilst it passes a sealing strip. The sealing strips are thereby fed with oil in sequence as the piston rotates. Lobe 3 is one of the lobes of the piston which is not subjected to high pressures during " compression " and " expansion " phases of the working cycle of operations, Fig. 10 (not shown). The outlet end of conduit 23 may comprise a plurality of openings, each of which may contain a flow restricting orifice or jet. Alternatively, an orifice or jet may be lodged in conduit 23 behind a single outlet opening, Figs. 8, 9 (not shown), or the said plurality of openings. Conduit 25 in the eccentric may contain a flowregulating valve, Fig. 11 (not shown), comprising a ball (32) biased to a closed position by a compression-spring (33) and a seat (31) containing one or a plurality of narrow by-pass passages (35), the valve being opened by centrifugal action at high speeds so that the pressure of the oil remains substantially constant with changes of speed. Alternatively, the valve may be of the needle type, Fig. 12 (not shown). The oil may be supplied to conduit 24 by the lubricating system for the bearings (not shown), or it may be supplied by a separate source. A further conduit 23<SP>1</SP> may be provided in a lobe similar to lobe 3 to increase the flow of oil to the sealing strips.

Class 59 Disintegrating apparatus comprises a revolving drum 1 having charging and discharge openings 2, 3, a fan in a casing 12 and a conduit 11 for forcing a stream of air and material to be disintegrated into the opening 2, and a discharge box 13 for receiving the disintegrated material from the opening 3, the discharge box having an outlet 15 for the disintegrated material suspended in the air stream and an outlet 16 for material dropping from the air stream. Material to be disintegrated is supplied to the conduit 11 by a shoot 10. The finely disintegrated material from the outlet 15 is conveyed by a conduit 17 to a separator 18 which further separates the material into fine and coarse material, the separated fine material being transferred by a conduit 19 to a cyclone collector 20 for the removal of air therefrom. The finally separated fine material is discharged from the collector 20 through a conduit 21 to a place of use or storage. The coarse material separated from the fine material in the separator 18 is returned to the conduit 11 through a conduit 23. The air separated from the fine material in the cyclone collector 20 is expelled through a conduit 27 to the inlet of the fan casing 12. The air stream leaving the fan casing is divided and a large percentage is delivered through a conduit 28 to a filter 29 having an outlet for fine material to be delivered by a conduit 30 to a place of storage. The coarse material which drops into the outlet 16 is delivered to the lower end of an elevator 32 having a discharge at the upper end arranged with a conduit 33 which is connected with the conduit 23 for the return of the material to the conduit 11. The discharge box is provided with a baffle 35 to prevent the return of coarse material to the drum. The air stream in the conduit 11 may be conveyed around the drum 1 and directly to the discharge conduit 17 through a valve-controlled pipe 36. To facilitate the disintegration of materials such as asbestos, the airstream entering the opening 2 is heated by a hot air furnace 38.

Title: Improvements in or relating to radio rediffusion systems or the like
IPC: H04H20/83
Filed: 1933-04-19
Abstract: 418,138. Distributing music &c. STANDARD TELEPHONES & CABLES, Ltd., LATIMER, K. E., and RENDALL, A. R. A., Connaught House, Aldwych, London. April 19, 1933, No. 11474. [Class 40 (iv).] Each programme line in a distribution system has associated therewith a device operated by the programme currents to give an indication of the load, that is, of the number of loudspeakers connected to the line. As shown in Fig. 1, an instrument 1 is used having two coils mounted at an angle and free to rotate in a non-uniform magnetic field. One coil receives a direct current proportional to the voltage across the line through a dummy load 8, transformer 10, filter 11 passing a suitable small band and rectifier 13, while the other receives a direct current proportional to the current in the line through a transformer 2, filter 5 similar to 11 and rectifier 4, so that the angular movement of the coils indicates the impedance or load on the line. The resistances in the circuits are chosen so as to make the currents in the coils more or less equal. In order to deliver a constant voltage to the subscribers instead of a constant voltage to the line, it is necessary to vary the transformer ratio between the amplifier and the line in addition to altering the number of amplifier units. These quantities are both functions of the load, and it is possible for the load indicator and the amplifier controls to be electrically or mechanically interconnected. In Fig. 2, 101-103 are amplifiers supplying different programmes as required to the lines 104-106 through plugs 107, the transformer ratio being controlled by the switches 108-110. In addition, these switches control the ratio of the transformers 111-113, corresponding to 2, Fig. 1, associated with the load indicators assigned to the lines 104-106. The indicators are provided in practice with two contacts on either side of the normal position, and upon closure of either contact when a change of load occurs, an alarm is operated and the attendant adjusts the number of amplifier units and rotates the switch of the appropriate line, thus bringing the indicator back to the normal position in order to respond to a further change of load. Alternatively, the indicator may be adjusted by varying the dummy load 114-116, corresponding to 8, Fig. 1. The load indicator may take the form of a central zero milliammeter upon which the outputs of the rectifiers 4, 13 act differentially. An electrostatic instrument may also be employed.
