Title: Improvements in guiding the pick-up or speaking head in talking machines
IPC: G11B3/08
Filed: 1954-09-08
Abstract: 775,497. Gramophones. RYSICK, A. Sept. 8, 1954, No. 26010/54. Class 40 (2). A carriage 26 for detachable electro-acoustic gramophone pickups travels radially of the record on rollers 30 on a rod 29 mounted in a frame 33 which is pivotally mounted at one side 34 so that the said frame may be lifted up and away from the record. The carriage 26 may be tilted about rod 29 by means of an eccentrically mounted adjacent parallel rod 37 whereby the pick-up 24 is lifted and lowered under the control of a lever 40 while the frame is in the lowered position. When the pick-up 24 is lifted and lowered, either by the operation of lever 40 or by the lifting and lowering of frame 33, the current to the turntable motor is interrupted and closed, respectively. The lever 40 is biased by means, not shown, to the right-hand or lifting position, but when the pick-up is lowered by lever 40, a tooth 60 on rod 37 moves away from the end of the lower contact 56 to permit it to close with contact 57 and becomes held back by a spring-loaded latch 58 until either the lever 40 is returned or the frame 33 lifted. If the frame 33 is lifted, a pin 36, normally held inwards while the frame 33 is lowered, moves outwardly (see Fig. 2) under the influence of a spring 62 and releases latch 58 from the tooth 60. The pick-up carriage may be backspaced across the record by merely pressing down the head 28 and then sliding the carriage back to a desired point. The pick-up may similarly be returned to the start of a record by sliding the carriage back until it is arrested by a projection 77 which may be set to one or other of two positions, according to the diameter of the record to be played, by means of a knob 74 on a slide 69 carrying the projection 77. The slide 69 carries contacts 66, 67 which are in parallel with contacts 56, 57, the contact 67 carrying a cam 80 which is pushed back by the carriage 26 at the end of the record to break the motor circuit.

Abstract: 601,776. Electromagnetic interrupters. LONDEX, Ltd., and BESSON, A. P. Oct. 11, 1945, No. 26612. [Class 38 (v)] The normally-closed contacts 2 of an electromagnetic interrupter for controlling a flashing-lamp 6 are connected in series with its coil 1, which is energized to open the contacts 2 and thereby extinguish the lamp 6, by the voltage built up across a condenser 3 in a time which may be varied by a resistor 5. The condenser 3 then discharges through the variable resistor 4, until after a pre-determined time, the contacts 2 re-close and the lamp 6 lights. A rectifier 7 prevents the condenser discharging through the lamp, but in a modification, Fig. 2 (not shown), the rectifier is replaced by a switch to which the lamp is connected, and which is actuated by the interrupter. The condenser may itself be variable.

Title: Improved servo-measuring system
Inventor: ROMANOWSKI ALBERT FRANK
IPC: G01F1/58
Filed: 1965-06-08
Abstract: 1,101,496. Potentiometric measurements. BOWSER Inc. June 8, 1965, No. 26723/67. Divided out of 1,101,495. Heading G1U. The A. C. output at terminals 30, 38, Fig. 5, of an induction type fluid flowmeter is balanced by a nulling signal from a transformer 92, the difference signal being amplified at 48 and changed successively into an amplitude varying D. C. signal at 68, and a phase varying A. C. signal applied to a winding 75 of a servomotor 76, which controls the amplitude of the nulling signal from transformer 92. The output of amplifier 48 drives a transformer 50, and a chopper 58. The armature 60 of this chopper is operated by an A. C. supply, on lines 78, which also energizes the magnetic field windings 16, 18, the connection to the chopper being made via an adjustable phase shifting circuit 96. The output of the chopper is unidirectional and is fed via a resistor 64 to the smoothing capacitor, 68, and the resulting D. C. is fed to the armature 61 of a second chopper which is also operated by the A. C. supply and which feeds a transformer 72 and a servoamplifier 74. The amplifier output is an A. C. signal, the phase of which is proportional to the amplitude of its input and therefore to the amplitude of the output of the first chopper, 58. The servoamplifier output energizes the winding 75 of a two-phase servomotor, 76, which drives a pointer, 80, and a moving tap, 84, on a potentiometer 86. The potentiometer 86, supplied with a 180‹ shifted signal from the A. C. source, applies the nulling signal via the transformer 92, the servomotor ceasing to operate when the net input to amplifier 94 is zero. When setting the zero of the apparatus under no-flow conditions, a small output occurs at the terminals 36, 38 due to the static liquid in the tubes, this output being phase-displaced from the A. C. supply, and therefore from the output of transformer 92, on account of various inductive and capacitive effects in the tube, Fig. 4 (not shown) and consequently the input to the amplifier, 48, cannot be completely reduced to zero. The A. C. driving the chopper 58 is therefore phase-adjusted at 96 so that the armature will rest on the two contacts 54, 56 respectively for a brief period embracing successive zero-cross-over points of the alternating output of the amplifier, 48. The chopper 58 output Fig. 6c (not shown) is then smoothed at 68, giving zero input to the next chopper. When the liquid flows, a substantial signal is developed across the tube terminals, and as the sum of this large signal and the output of the nulling amplifier 92, does not have the same zero cross-over points as the net signal under no flow conditions, an output appears from chopper, 58, Fig. 6d (not shown) and the servomotor operates to move the pointer, 80, and to adjust the potentiometer 86, and balance the system as described.

Title: Machine for forming butter into pats or blocks
IPC: A01J21/02
Filed: 1930-09-09
Abstract: 361,032. Moulding butter &c. pats ; ratchet gearing. MACQUEEN, J., 49, Cadogan Street, Glasgow. Sept. 9, 1930, No. 26841. [Class 87 (ii).] In machines for forming butter or the like into pats, including a receiver 1 with a discharge nozzle 2, a plunger 3, means for advancing the plunger step by step, and means for severing the butter emerging from the nozzle, the plunger is operated by a leading screw 4 engaged by a nut 5 deriving rotation from ratchet and pawl mechanism 21<1>, 22<1>, 23, 24, from the movements of a crank handle 6, and the butter is severed by a wire 8 carried by a frame 9 adapted to perform combined rocking and oscillatory movements so as to sweep the nozzle in its forward movement and pass clear of it in its rearward movement. An arm 10 is rocked by the screw 4 and presents a slot 11 engaged by a cranked rod 13 pivoted at 22 and carrying the frame 9. A pendulous escapement lever 15 is pivoted at 14 to the arm 10 and is engaged by a striker pin 17 on the crank handle 6. A concave face 18 on the lever 15 engages with a convex face 19 on a fixed member 20 during a portion of the movement so that the lever 15 is locked about its pivot 14 and the movements of the handle 6 are transmitted direct to the rod 13. A cam segment 31, Fig. 2, always engages one pawl and the other pawl only is operative, so that rocking the handle 6 imparts intermittent unidirectional motion to the screw 4 and plunger 3. The direction is reversed by rotation of the handle 6 bringing the cam 31 into engagement with the other pawl. The receiver 1 is clamped in position by a yoke 36 pivoted at 37 and carries notches 1<1> which engage snugs 1<2> on a frame 30 holding the mechanism. The discharge nozzle 2 is interchangeable.
