Filed: 1953-12-07
Abstract: 737,546. Magnetic amplifiers. GENERAL ELECTRIC CO. Dec. 7, 1953 [Dec. 5, 1952], No. 33998/53. Class 40 (4). In a self-saturating magnetic amplifier, the A.C. windings 2, 3 are connected to a constant voltage supply 10 through a saturable reactor 12 which has its D.C. winding 13 energized from the amplifier output, the arrangement being such that the reactor varies the voltage across the A.C. windings and so causes the amplifier gain to increase. As shown, the amplifier comprises a core 1 having a control winding 4 and a differentially-acting bias winding. 15 in addition to the windings 2, 3. A full-wave bridge rectifier 6 establishes both self-saturation and a direct current output to a load 9. The bias winding is supplied through a rectifier 16 from a bleeder resistance 14 connected across the amplifier, the resistance ensuring that a wide variation in voltage across the windings 2, 3 is obtained by reducing the variation in A.C. current through the reactor. In a simplified arrangement, Fig. 1 (not shown), the bias winding is omitted. Where an alternating output is required the reactor has its D.C. winding energized over a separate rectifier either directly or through a current transformer.

Abstract: 1,057,799. Fluid-pressure servomotor systems. ROBERTSHAW CONTROLS CO. Aug. 10, 1965 [Aug. 11, 1964 No. 34224/65. Heading G3P. In a pneumatic thermostat, a fall in the ambient temperature causes a bi-metal flapper 68 to seat against a nozzle 62, supplied via restriction 18 from a supply chamber PS, thereby causing the pressure in a chamber PP to rise and lift a diaphragm 20 to rotate a lever 42 about its pivot 52, such rotation unseating a valve 34 to admit supply pressure to a chamber PB communicating at 30 with a device for varying the ambient temperature. The increased pressure in chamber PB is communicated to a chamber PF where it acts via diaphragm 26, lever 78 and spring 86 to provide a feedback to the flapper. If the pressure in chamber PP decreases, the accompanying clockwise rotation of lever 42 unseats a valve 40 to vent chamber PB. The flapper is pivoted at 71 and a cam 76 is rotatable to vary the set point temperature via a pin 72 and lever 70. In the practical embodiment of Figs. 2-7 (not shown), a U-shaped spring 150 is located between the flapper and lever 70 and serves to ensure that the end of the flapper is always parallel to the nozzle when it engages the latter. A resilient extention 134 of the feedback lever 78 (Fig. 5) engages a clip 138 which is adjustable to vary the force exerted by the lever on the flapper.

Title: A new or improved arrangement for the remote control of toys
IPC: A63H30/04
Filed: 1956-11-12
Abstract: 848,454. Remotely controlled toys. NOTHELFER, W. Nov. 12, 1956 [April 12, 1956], No. 34576/56. Class 132(3). [Also in Group XXXVIII] In a toy vehicle, remotely controlled by light rays, sound or electromagnetic wave signals, a signal pulse of any length initiates steering control and a signal pulse exceeding a predetermined duration initiates operation of a reversing switch to a driving motor. In the circuit shown in Fig. 1, an audio signal, e.g. a human voice, a bell, a whistle or a buzzer, is received by a microphone 1 and the pulse set up in the microphone circuit is rectified at 5 and operates a relay 6 and switch 7 to actuate an electromagnet 8 which attracts a spring loaded pawl 9 which in turn releases a lever 10 from a snout 13, the lever then being rotated by a driving mechanism, e.g. a spring motor, until it engages a snout 11. When the pulse ceases, the magnet 8 releases the spring loaded pawl 9 and the lever 10 is released from the snout 11 and completes its rotation to the snout 13, rotation of the lever effecting, through gears 14, 15 and a pin 16, change in the toy's steering. Attraction of the pawl 9 by the magnet 8 also makes a contact 23 and completes a circuit including an electromagnet 24, which actuates stepwise operation of a reversing switch 53 to a motor 30, and time delay means 25, 26 which ensure that only pulses exceeding a predetermined duration are effective in operating the switch 53. To increase the sensitivity of the microphone 1, a transistor amplifier may be incorporated in the microphone circuit. In a further embodiment, Fig. 5, pulses received at E actuate a magnet coil 38 which operates a step-by-step switch 38<SP>1</SP> and a control drum 39 in circuit with a control motor 37. A pulse of any length switches on the control motor which turns a gear wheel 15 to effect steering through a pin 16. To limit the travel of the pin to 90 degrees, the gear 15 carries contact pieces 43 which, during rotation of the gear, brush against a contact spring 41 and complete a circuit to the magnet coil 38 to operate the switch 38<SP>1</SP> and stop the control motor. Operation of the switch 38<SP>1</SP> also makes a contact 23 and if the control pulse is sufficiently long that the contact 23 is still made when contact piece 43 brushes a contact 42 then a circuit including the magnet coil 24 is completed which operates a switch 51 controlling the toy's driving motor. Each of the pulses may control more than one function, e.g. a third control circuit or further circuits can be released by the control magnet 24 as shown in Fig. 3, e.g. a lighting circuit may be switched on and off. Frequency dependent elements may be used in combination with the time dependent elements. A watertight microphone can be used underwater in a model boat. The microphone can be replaced by a receiver for electromagnetic waves or a receiver for light waves.

Abstract: 908,312. Respiratory appliances. WHITTINGTON, P. E. Oct. 10, 1960 [March 15, 1960], No. 34582/60. Class 81 (2). A protective suit 1 is supplied with gas from a liquid oxygen container 3 through a heat exchange coil 6, which is enclosed in a casing 5. On leaving the coil 6, the oxygen passes through a Venturi arrangement 13 before being distributed through tubes 16 to the suit. The Venturi causes air to be withdrawn from the suit through a tube 17 and to pass downwards over the tubes 6 and up through an inner baffle 18. This results in cooling of the enclosed air and the removal of moisture by freezing on the tubes 6. Excess air is allowed to escape through a valve 19 in the helmet.

Abstract: 809,078. Flushing cisterns. IDEAL BOILERS & RADIATORS Ltd. Dec. 7, 1955 [Aug. 22, 1955], No. 35171/55. Class 26. The syphon 3 (see Fig. 1) of a flushing cistern 1 is provided with an air inlet aperture 6, closable by a valve member 17 so that the discharge of the cistern may be complete, while when a smaller volume is sufficient the discharge may be interrupted when the level falls to aperture 6. The member 17 is freely slidable on the actuating spindle 14 of plunger 15 and has an annular valve seating 20 and a pin 19 normally supporting it in the position shown ; when chain 12 is pulled the upward flow of water in the cylindrical part 4 of syphon 3 causes the member 17 to close aperture 6 and the syphon is primed. If the chain is then released the plunger will fall slightly from its topmost position, and so will member 17, so that the discharge continues through aperture 6 and the lower end of the syphon leg until the water level in the cistern falls to aperture 6 when air enters, breaking the syphon. If the chain is held down the plunger 15 will hold member 17 up to keep aperture 6 closed, allowing complete discharge. Fig. 6 shows a modification in which an arm 26 with a finger 26a capable of engaging pin 19 to hold member 17 in its uppermost position is provided, this arm 26 being pivotted at 21 ; in the position shown it is held clear of pin 19 by a lever 22a mounted on a spindle 23 which is provided with an external operating lever so that the operation will be as already described in connexion with Fig. 1. The second position of the operating lever turns lever 22a through 90 degrees anticlockwise from the position shown, carrying with it an abutment 22b freely rotatable on spindle 23 but which engages a step on lever 22a when moved clockwise relative to it from the position shown. This movement of the lever takes place when the member 17 and plunger 15 are in their normal lower positions, the pin 19 resting on the wall of syphon 4 supporting the finger 26a and a collar 24 on spindle 14 being below abutment 22b. When the chain is pulled spindle 14 moves upwards and collar 24 lifts abutment 22b which moves without disturbing lever 22a and then falls back to its horizontal position, the valve member 17 next being lifted by plunger 15 and retained by finger 26a which engages its underside by anticlockwise rotation of arm 26. Release of the chain now does not allow member 17 to fall, since the plunger 15 falls only slightly. At the end of the discharge, plunger 15 falls still further and collar 24 falls to engage abutment 22b and rotate it and lever 22a back to the position shown, releasing pin 19 and returning member 17 to its lower position.
