IPC: G11B27/32
Filed: 1964-01-22
Abstract: 1,109,423. Magnetic tape recorders. CENTRALISED DICTATION Ltd. 22 April, 1965 [22 Jan., 1964], No. 2863/64. Heading G5R. A multi-track tape carries a series of recorded items on one track and additional signals on a separate track which can be separately detected to indicate the position of the reading head along the tape. Between adjacent recordings T1 are added tone bursts on track T2. The bursts have a low frequency component which is effective during fast wind and rewind and a high frequency component which operates when the tape is travelling at play-back speed. The operator presses a button B, Fig. 1, or dials on a telephone dial, Fig. 3 (not shown) and the tape runs at fast wind speed. A counter CR counts the pulses from head H2, H1 being muted. When the correct number has been counted, the control circuit C switches the recorder to normal playing speed and renders head HI operative. At the end of the item, a pulse from track H2 is effective to cause the control circuit C to switch off head H1 and set the rewinder to fast rewind. The counter now counts the pulses in the reverse direction and when it reaches zero, switches off the tape recorder. The recorded items may be pulses for controlling or selecting other equipment.

Abstract: 825,269. Fluid-pressure servomotor-control systems. LANDIS & GYR A.G. Jan. 29, 1958 [Feb. 7, 1957], No. 2961/58. Class 135. A thermostatic valve comprises a capsule 17 adjustable at 19 and connected at 18 to a thermal feeler for alternatively positioning two connected valves 21, 22 with respect to opposite ends of a valve seat 14 and controlling the leakoff of high pressure from a chamber 9 on one side of a diaphragm 7 supplied by a throttle 12 from the inlet 2 to a Venturi 10, a leak-off leading via 15 and 13 to the throat of the Venturi and a low-pressure chamber 8 beneath the diaphragm, the diaphragm actuating a valve 5 controlling heating or cooling medium flowing through the passage containing the Venturi. With heating medium flowing through the Venturi to a room heat-exchanger, a rise in room temperature makes the capsule 17 move the valve 21 towards its seat at top of the opening 14 so that diaphragm 7 descends and closes valve 5. When cooling medium flows, a bimetal strip 24 is cooled and snaps upwards whereby valve 21 is moved away from the opening 14 and valve 22 is moved to control the lower side of the opening whereby rise of temperature in the cooled space makes capsule 17 move valve 22 away from its seat whereby diaphragm 7 rises and opens valve 5. In a further embodiment the spring 27 loading valve 5 is replaced by a diaphragm loaded by inlet pressure and a spring-controlled lost-motion device is incorporated in the stem 20 to prevent the strip 24 damaging the diaphragm.

Abstract: 843,475. Measuring gravity. BOITNOTT, B. D. Jan. 28, 1957 [Nov. 27, 1956], No. 2996/57. Class 97(3) [Also in Group XXXVIII] An instrument particularly for use in airborne gravitational geophysical exploration comprises a plurality of gravity-responsive masses supported one above the other so that the differential influence of gravity causes them to have relatively opposite vertical movements. Variations in the separation of the masses thus give a measure of the second differential of g at the point of measurement, and by traversing an area such variations can be monitored or recorded, e.g. graphically or on tape. In the Figure the masses 1 and 2, identical in weight and of non-magnetic electricallyconducting material such as gold or silver, are suspended in vertical alignment from a head piece 5 which is in turn hung from a frame 10. Relative movement of the masses is detected electrically (see Group XXXVIII) by means of capacitance plates 13, 14 separated by a conducting non-magnetic screen 15. The whole device is contained in a tubular conducting non- magnetic shield 16. Means are provided to damp out natural oscillations of the masses and to eliminate effects due to the horizontal component of g.

Abstract: 1,143,101. Electric correspondence control systems. SULZER BROS. Ltd. Feb. 18, 1966 [Feb. 18, 1965], No.3139/66. Heading G1N. [Also in Division F1] In a positional control system, a control signal is produced manually, the response signal is measured by a differential transformer, and this error signal is modified by a stabilizing signal. As described, the controlled member is the spindle for the injection pumps of an I. C. engine acting against a spring-bias, which is coupled to a cam determining the position of the core of a differential transformer. The signal from the transformer is compared with the control signal, derived from the slider of a potentiometer, and the difference fed through an amplifier and silicon controlled rectifiers to an electromagnet determining the position of the spindle. The response signal is augmented by a stabilizing signal proportional to the current through the electromagnet, developed in a series resistor or in a coil coupled to the energizing coil of the electromagnet and then integrated, to which the differential of the response signal may also be added.

Abstract: 1,024,663. Measuring fluid flow electrically. ELLIOTT BROS (LONDON) Ltd. Jan. 23, 1964 [Jan. 25, 1963], No. 3267/63. Heading G1N. A transducer for measuring the mass rate of flow of a fluid through a conduit comprises a duct 11 (Fig. 1) having a number of stationary vanes 12 which remove any angular velocity, followed by an impeller 13 carrying rotatable vanes 13a and a shroud 13b, coupled to a motor 15 by a torsion spring 16, and surrounded by a cylindrical drum 14 rigidly coupled to the motor 15, whereby the lag between the impeller 13 and the drum 14 when both are driven by the motor 15 is indicative of the mess flow of the fluid through the duct. The impeller and the drum each carry a magnet 17, 17<SP>1</SP> which produce pulses in external coils 18, 18<SP>1</SP> respectively during rotation, the pulses coinciding at zero fluid flow. The motor 15 is energized by an oscillator 19 (Fig. 2) feeding through an adjustable frequency divider 21. The measuring pulses are amplified at 25, 26 and taken to a bi-stable switch 27 which produces a square pulse whose duration is equal to the interval between the measuring pulses,and opens a gate 33 to allow clock pulses from oscillator 19 to be counted during this interval for indication on a counter 35. The time interval is also measured in analogue form by comparing it in a difference circuit 37 with a pulse length determined by a potentiometer 46 and automatically adjusted to give zero difference. The angular velocity of motor 15 can be adjusted to a higher or lower value, by a switch associated with the frequency divider 21, to deal more easily with a smaller or larger mass flow rate.

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D23/04
Filed: 1941-03-11
Abstract: 548,111. Lasting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and ROBERTS, W.T.B. March 11, 1941. No. 3281. Addition to 489,649. [Class 17 (i)] In the machine described in Specification 470,749 modified as described in Specification 482,275 and the parent Specification, the heightwise operative position of the heel-end abutment is automatically determined according to the position of the shoe in the machine. Also, the last-pin support is mounted for transverse movement, to accommodate shoes made on lasts having pronounced heel swing. The heel-end abutment moves transversely with the last-pin support, the latter rotating about its own axis to cause the abutment to be given the necessary greater transverse movement than the last-pin. The last-pin support has three bores 43 and the last-pin has a frusto-conical portion 47 so that it may be used with last-pin holes of different sizes. The pin is carried by a rod 23 pivoted at 25 to swing longitudinally of the shoe and at 29 to swing transversely, the latter pivot being carried by a slide 31 urged upwardly by light springs 49 and locked in operative position by pawls 51. The rod 23 carries a collar 63 having an extension 65 in a bifurcated arm 67, and the heel end abutment support 73 is pivoted to the support for the rod 23, this construction providing a greater transverse swing of the .heel-end abutment than that of the last-pin. The rod 73 carries a pair of rods 77 supporting trunnions on an annulus 78 supporting extension 79 of a concave heel-end abutment 93. The extension 79 has a depending plate 81, can turn in the annulus 78 under friction provided by two springs 85, 87,.and is formed with longitudinal grooves 83. The heel-end abutment is moved rearwardly by a thrust member 95 secured to a slide 97 raised by rods 109 described in the prior Specifications as raising the toe-rest. The member 95 engages a lug 143, and is corrugated to engage the grooves 83 and thus lock the work against transverse movement. The thrust member 95 is locked in its upper position by pawls 121 operated with the other locking mechanism.
