Abstract: 949,597. Tank closures. GENERAL MOTORS Ltd. Aug. 3, 1962 [Aug. 21, 1961], No. 30155/61. Heading B8T. A fuel tank closure cup 1 detachably secured to the end of a filler neck 16 houses a spring disc 4 attached to the cap by a rivet 5, and a cup 6 retained within the cap by lugs 3. The spring disc and cup have vent openings 14 and 12 respectively. The spring disc 4 forces the rim 10 of the cup 6 into contact with the upper surface 17 of the filler neck 16 when the cap is applied. The fluid seal between the spring disc 4 and the cup rim 10, and between the rim 10 and the filler neck may be improved by annular gaskets. Rivet 5 may be omitted and the spring disc 4, retained by lugs 3, located centrally of the cap 1 by means of central depressions in the cap and disc. The disc securing rivet may extend through an enlarged central vent in the cup and a flange thereon contacts the undersurface of the cup when the cap is removed from the filler neck, but leaves an annular vent opening when the cap is applied.

Abstract: 890,841. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Sept. 26, 1958 [Sept. 27, 1957], No. 30826/58. Class 37. A power transistor is mounted on an electrically and heat conductive support with a region of heat conductive semi-conductor of opposite conductivity type to the adjacent zone of the transistor disposed between said zone and the support. The PN junction formed between the region and the adjacent zone of the transistor is reverse biased in operation to prevent leakage of current to earth. In one embodiment, Fig. 1, a conventional junction transistor of the type in which the collector zone is in direct contact with the casing 9 to facilitate cooling is mounted on an earthed metal chassis through the intermediary of a semi-conductor washer 15 of opposite conductivity type to the collector zone. Alternatively, a washer with a PN junction between its opposite faces may be used. The mounting nut and washer 13, 18 are insulated from the chassis by grommet 17. In another embodiment, Fig. 3, a junction transistor is mounted in a casing 27 on the head of mounting bolt 24. In this case the collector zone is isolated from the casing and bolt by a semi-conductor coating or body 25, of opposite conductivity type to that of the collector zone, on the head of the mounting bolt. The casing may in this case be mounted as shown direct to the chassis. In each of these embodiments the collector zone may be maintained positive or negative to earth respectively when it is N or P type while being in good thermal contact through the additional semi-conductor body with the chassis.

Title: An electric harmonic analyzer
IPC: G01R23/00
Filed: 1920-11-03
Abstract: 174,744. Walker, M. Nov. 3, 1920. Current meters.-An harmonic analyzer for measuring the amplitudes of the harmonics in an alternating-current supply comprises a wattmeter connected up to take through one coil the current to be investigated and through the other coil a sinusoidal current of frequency equal to that of the harmonic to be examined, and means for generating the sinusoidal current, consisting of a resonating circuit formed by a capacity in series with an inductance, which can be tuned to the frequency of the selected harmonic, and means for impressing forced vibrations upon this circuit in synchronism with the supply under test. 'The auxiliary supply for the tuned circuit' may be a small alternator, or a commutator associated with a continuous current supply, driven from the main supply by a synchronous motor and ad. justed for different frequencies by change gearing or by changing the commutator bars, and for phase relations by rocking the frame of the alternator or the brushes of the commutator; or the main supply may excite an auxiliary tuned circuit, which excites the wattmeter circuit and is adjustable for frequency and phase. The wattmeter coil may serve as the inductance in the resonating circuit, and should have a high ratio of inductance to resistance at high frequency. The current in this circuit may be determined by using an electrostatic voltmeter, the impedance of the coil being known, or may be measured directly by an ammeter, or by providing a pivoted arm strip so that the wattmeter coil functions as an ammeter. From the amplitude of the current thus obtained and the deflexion of the wattmeter, the voltage of the selected harmonic can be calculated. Fig. A shows a commutator arrangement, the supply mains 3 being connected through a resistance 2 to the moving coil 1 of the wattmeter, and also to a synchronous motor 14 driving a commutator 6, the brushes of which are connected to a battery 8 and a resistance 9. The other coil 4 of the wattmeter is in series with a condenser 5 and connected through simple conductors, resistances, transformers, or condensers 11 to slip rings 7 connected to the commutator bars. A voltmeter 13 is connected to the terminals of the coil 4, and a pivoted strip 12 is provided to form an ammeter. Fig. B shows an arrangement in which the supply mains 3 connected to the wattmeter coil 1 are also connected to an auxiliary tuned circuit 15, 16, which excites the tuned wattmeter circuit 4, 5 through branch circuits 17, 18, 19, 20 adjustable for phase.

Abstract: 744,409. Cathode-ray oscilloscopes. BOULTON PAUL AIRCRAFT, Ltd. Dec. 9, 1953 [Dec. 9, 1952], No. 31197/52. Addition to 696,447. Class 37. [Also in Group XL (c)] The parent Specification describes with respect to Fig. 5 thereof a multi-chamber display apparatus in which the output from a 2000 c/s carrier frequency oscillator is applied in parallel to a plurality of transducers, e.g. strain gauges, which modulate the amplitude of the carrier frequency in accordance with the physical quantities to be displayed, the modulated output from each transducer being applied through a separate amplifier to the Y-plates of a corresponding cathode-ray tube. Two trains of brightening pulses derived from the oscillator are also applied in parallel to each cathode-ray tube to display thereon the modulation envelope of the applied signal and a datum line. Since the brightening pulses are synchronized with the carrier frequency the phase characteristics of the parallel channels must be identical and this is achieved according to the present invention by incorporating into the amplifier or between the transducer and amplifier of each channel an adjustable phase shifter. As shown, each amplifier comprises two negative feed-back pentodes 1 and 2 with an intermediate resistance-capacity phase shift network 3 ... 7.
