Abstract: 197,328. Tomadelli Corporation, (Assignees of Tomadelli, J. J.). May 5, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Utilizing atomic disintegration.- Energy especially for the production of light, is generated by causing progressive atomic disintegration of matter, and is directed in a predetermined path. A lamp is described wherein a filament a, b, c of oxidized copper or silver is mounted in a bulb containing air at about atmospheric pressure, the leading-in wires 14, 15 passing out and contacting with a metal plate 26 with which they form a closed circuit. Another closed circuit consists of the plate 26, two cylinders A, B separated by an insulating partition, and a metal plate 27. The cylinder A is composed of a mixture of sun-dried sea salt and powdered metal, preferably tin, agglomerated by means of paraffin wax, and the cylinder B is composed of powdered copper mixed with asphalt. At first, the plate 27 is separated by a perforated' mica plate 28 from metal plates 25 placed on the ends of the cylinders A, B, but these become fused together through the perforations in the mica by applying to the plate 27 electrodes, inserted through apertures 22, 23 in the end of the container 20, serving to conduct electricity of extremely high voltage, high frequency, and low amperage. This current is stated to start the atomic disintegration of the sea salt, which subsequently proceeds automatically, the released energy proceeding to the filament.

Title: Improvements in and relating to inductor-controlled electrical circuits including electron discharge devices
IPC: G05B11/01
Filed: 1952-05-09
Abstract: 708,161. Dynamometers. BRITISH THOMSON-HOUSTON CO., Ltd. May 9, 1952 [May 9, 1951], No. 11792/52. Class 106 (2). [Also in Groups XXXV, XXXVI, XXXVIII and XL(c)] The amplitude of oscillations produced by a Colpitts oscillator is varied by inserting a variable inductor in the cathode lead and is used to measure strain, force or acceleration. As shown in Fig. 1, the inductor 5 is connected between the cathode and the junction of the grid-cathode condenser 6 and the anode-cathode condenser 8. The inductor 5 may be in parallel with a condenser 13, and the inductor variations are such that the tuning of the circuit 5, 13 varies within limits at one side of the oscillation frequency, Fig. 2 (not shown).. The varying impedance of the circuit 5, 13 varies the negative feedback, and so controls the oscillation amplitude. Bias for the grid is provided by a condenser 9 and resistor 10, and anode current is supplied from a source 12 through a choke 11. The oscillatory output is fed to a grid leak detector 22, and a load 26 is inserted in the anode lead. In a modified circuit, Fig. 3 (not shown), a series condenser replaces the shunt condenser 13, and the inductor 5 is varied within limits close to but above the resonance value. The oscillatory output is rectified by rectifiers connected in the grid circuit of the output valve 22. In Fig. 7 the inductor comprises a coil 64 on a U-shaped ferrite core 65, the reluctance of the magnetic circuit being varied by adjusting the air gap between the core 65 and a movable armature 66. This type of variable inductor may be used as a strain gauge. Fig. 8 shows an application to the measurement of the force 83 applied to a weak spring 82 supporting an armature 81. As the gap between the armature and the U-shaped core 80 of the inductor is diminished, the negative feed-back of the valve oscillator 67 is increased, and the oscillation amplitude reduced. The oscillations are rectified by the rectifiers 91, 92 and charge the condenser 90 negatively. A reduction of oscillation amplitude therefore drives the grid of the valve 86 in the positive direction causing an increased anode current through the indicator 97 and the electromagnet 94. The magnet 94 opposes and balances the applied force 83, the magnitude of which is shown on the indicator. If the force 83 is that of gravity acting on an object, the indicator shows the weight of the object. If the system is mounted on a moving body, the force 83 may be that due to acceleration of the body.

Refrigerating, compression machines for; refrigerators, domestic. - A machine somewhat similar to that described in Specification 244,768 comprises a single oscillating-cylinder compressor 6 mounted within a casing 9, Fig. 1, containing an electric driving motor 16, and condenser coils 22 arranged around the casing and supported in notches in the edges of the radial vanes 24 which serve to dissipate heat from the casing and from the coils. The machine mav be secured on the top 1 of a refrigerator by angle brackets 13 concealed by an apron 14, and the lower portion 9<1> of the casing may be flared and secured to -the base plate 12 through lugs 10. The compressor is supported in a frame 4 the upper end of which is resiliently held in contact with the stator of the motor by pins 20 and springs 21. The inner edges of the radial vanes are connected in pairs by narrow strips and are of less depth than the outer edges. They may be secured to the lugs 10. Holes 26 are provided in the vanes, preferably at such greater distance from the inner than the outer edges as to ensure dissipation of more heat from the casing than from the condenser. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the following subject-matter :-The refrigerant, preferably sulphur dioxide, from the evaporator 3, Fig. 1, flows by a pipe 58, check valve 60, Fig. 4 (Cancelled), and passages 61, 62 to a suction port 63 in the cylinder and is discharged into the interior of the casing 9. A passage 68, Fig. 3 (Cancelled), provides communication between the delivery side and a pipe 65, Fig. 4 (Cancelled), opening into the valve 60 of the suction passages so as to equalize the pressures at starting, a valve 70 on a piston 55 being raised to close the passage 65 when an oil pump, described below, builds up sufficient pressure after starting. To allow the gas to pass freely to the condenser the rotor of the driving motor is provided with passages 29 which are inclined so as to separate lubricant by centrifugal action. The compressor is partly submerged in an oil bath 46, Fig. 1, and a rod 48, Fig. 3 (Cancelled), carried by the compressor piston forms the piston of an oil pump cylinder 47 communicating alternately with suction and delivery passages 50, 51, Fig. 4 (Cancelled). The oil is forced through a passage 52, Fig. 3 (Cancelled), and serves normally to hold the valve piston 55 in the raised position, and then flows by a passage 53 to a space around the motor shaft 5. Part of the oil flows by a small bore passage 56 through the shaft to the crank pin bush 43 and part flows through a larger opening 57 leading by a spiral groove 57<1> to the upper thrust bearing. The evaporator 3, provided with cold-accumulating chambers, is constructed as described in Specification 293,773. This subject-matter does not appear in the Specification as accepted.

Filed: 1926-05-05
Abstract: 251,994. British Thomson-Houston Co., Ltd., (Assignees of McDonald, G. R.). May 6, 1925, [Convention date]. Systems depending on two or more machines. -An electric control device comprising a pair of shading ring motors 23. 24 is applied to a system comprising a synchronous motor 1 supplied from lines 2 and driving a generator 4 supplying a distribution circuit 5, it being desirable to supply the field of the motor 1 from the generator 5 by the closure of switch 6 when the generator speed bears a certain relation to the frequency of the lines 2. The motor 24 is supplied from the lines 2 through a transformer 34, and the motor 23 from slip rings 38 on the generator. Assuming the line frequency is constant and the generator to be increasing in speed the torques exerted by the stators 29. 30 upon the motor 24 will remain constant, whereas the torque of the stator 27 upon the motor 23 will increase relatively to that of the stator 28 owing to a condenser 39 being included in the circuit of the winding of the stator 27. Thus the motor will turn anticlockwise and close contact 14 on to fixed contacts 13, 15. This results in the energization of switch coil 16, to close switches 10<1>, 17, the former causing closure of the switch 6 and the latter completing a " hold on " circuit for the coil 16. Should the speed of the generator fall, the motors 23. 24 turn clockwise, and close contact 14 on to fixed contacts 18, 19 thereby shorting switch coil 16 and opening switches 10<1>, 17, 6. A condenser 35 in circuit with the winding of stator 29 causes a similar action should the speed of the generator 4 be constant and the frequency of the lines 2 be changing.
