Title: Improvements in or relating to talking machines and the like
IPC: G11B17/02
Filed: 1919-02-17
Abstract: 138,995. Barnett, C. J. Feb. 17,1919. Raising sound-boxes; turntables; starting and stopping.-The needle is automatically separated from the record, and the turntable arrested, if desired, at the conclusion of a reproduction, or at any suitable point, by providing a trigger releasable by the tone-arm, the trigger normally holding up a spring-controlled member which, when released, actuates mechanism for raising the sound-box or lowering the turntable. The trigger is reset by returning the tone-arm to the outer edge of the record. The tone-arm 38, Fig. 1, carries an adjustable arm 40 which lies between a trigger arm 20 and a lever 22. The trigger cooperates with a stop 21 on the lever 22, normally holding the lever in its right-hand position against the tension of a spring. The lever 22 is pivoted on a pin 23 and is connected by a link 24 and bell-crank lever 25 to a pulley 27 slidable vertically on the turntable spindle 11. When the pulley 27 is raised, it is clutched to the spindle 11 by the pins 28, 29. A friction band 30 surrounding the pulley 27 is connected by a link 32, bell-crank 33, and link 35 to an horizontal lever 34 on which rests a vertical rod 43 attached to the tone-arm. At the end of a record, the arm 40 trips the trigger 20, causing the pulley 27 to be engaged with the turntable spindle 11. The friction band is rotated for a short distance, causing the tonearm and sound-box to be raised, the friction band then acting as a brake and arresting the turntable. To re-start the machine, the tone-arm is moved beyond the turntable rim, bringing the arm 40, or a separate arm, into engagement with the lever 22, resetting the parts in initial position, and allowing the trigger 20 to re-engage. The motor and driving-mechanism are mounted between a platform 2 integral with the horn 1 and a plate 7 secured to brackets 5, 6. The trigger 20 and lever 22 are pivoted on a vertical plate 19 secured to the horn 1. In a modification, Fig. 5, the friction ring 30 surrounding the pulley 27 is connected to a cord 50, which passes over fixed pulleys 51, 53 and a tensioning-pulley 52 and is secured to a lever 49 on the gooseneck pivot, the sound-box being raised as the pulley 27 rotates. In a further modification, Fig. 4, the turntable 12 is lowered away from the sound-box and brought into contact with fixed brake blocks 48 when a record is completed. For this purpose, the turntable spindle 11 and its footstep bearing 45 are arranged to slide vertically under the control of tha lever 25, which is connected by a link 24 to an extension of the lever 22. The weight of the turntable is partly balanced by a weight 46 mounted on a lever 47 connected to the link 24.

The angular velocities of a plurality of shafts having different maximum angular velocities are indicated on a single meter. Each shaft has connected thereto a low reluctance disc provided with a set of circumferentially equally spaced apertures and each disc is associated with a respective variable reluctance pick-up 10, 12, 14, Fig. 3 (not shown) which provides an A. C. voltage of frequency proportional to the number of apertures of the respective disc and the angular velocity of its shaft. The number of apertures in each disc is chosen so that the induced alternating voltages have the same maximum frequency corresponding to the different maximum angular velocity of the shafts. The A. C. voltages from the pick-ups 10, 12, 14 are individually selected by switch 16 and applied to a normally saturated transistor 30 to render the latter non-conductive during negative half-cycles. The output pulses at the collector of transistor 30, having a pulse width inversely proportional to the frequency of the A. C. voltage, are differentiated at 46, 48 and fed to meter 28, Fig. 2 (not shown). Each disc may be provided with a plurality of sets of apertures, each set being spaced at a different radial distance from the centre of the disc and corresponding to a different maximum angular velocity of the shafts to allow them to be interchanged.

Title: Transmission and recording of signals in echo-sounding apparatus
Inventor: BUFFERY VICTOR CHARLES
IPC: G01S7/60
Filed: 1964-01-31
Abstract: 1,042,124. Echo-sounding. SMITHS INDUSTRIES Ltd. Jan. 13, 1965 [Jan. 31, 1964], No. 43150/64. Heading H4D. [Also in Division G1] In an echo-recorder for use with hydrographic surveying, oceanographic, navigational, fish-detection, or flaw-detection echo-sounding apparatus in which a recording stylus is moved across the recording medium by an endless belt, the transmission of an acoustic pulse is synchronized with the movement of the stylus by means of two rotary switches which are driven from the belt and whose relative speed of rotation is such that both switches operate simultaneously once in each complete circuit of the belt to trigger the transmitter. In the embodiment of Fig. 3 a belt 23, e.g. a toothed belt or a chain, runs on wheels 22 and 24 and carries the stylus 17 of the recorder (Fig. 1, not shown) which may be of the electrochemical type. The two rotary switches comprise contacts 27, 29 on the wheels 22, 24, which co-act with stationary contacts 28, 30 respectively. The dimensions of the wheels and belt are such that for one circuit of the belt wheel 22 makes 3 complete revolutions and wheel 24 makes 5 complete revolutions, both switches operating simultaneously when the stylus 17 is in the position shown. In order to record from different ranges, the instant of transmission may be advanced or retarded (in relation to the 'position of stylus 17) by moving contact 28 to one of four alternative positions 28a-28d equally spaced round the circumference of wheel 22 (Figs. 2a-2e, not shown), or by selecting a stationary contact at one of these positions by means of a switch 36. For an incremental range adjustment, e.g. to compensate for displacement of the transmitter from a datum level, the angular positions of both stationary contacts 28, 30 may be adjusted continuously between fixed limits (Figs. 4, 5, 6, not shown), the two angular adjustments being ganged together, e.g. by a toothed belt (Fig. 7, not shown), such that the contacts 28, 30 are rotated through angles having the same ratio as the angular speeds of the respective rotary contacts 27, 29. In an alternative embodiment (Figs. 8, 9, not shown) the two rotary switches comprise drums 60, 67 having respective conducting strips 61, 68 for bridging pairs of contact arms, one drum 60 being driven directly from the toothed belt and the other drum 67 being driven through gearing from the first drum 60. Instead of mechanical contacts, the rotary switches may employ cams, photoelectric or electromagnetic induction switching systems.
