Abstract: 393,722. Converting. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London. - (Assignees of Stansbury, C.; N. 12th Street, Milwaukee, Wisconsin, U.S.A.) March 21, 1932, No. 8337. Convention date, March 20, 1931. [Class 38 (ii).] A tube having a cathode 2, an anode 3, a control grid 4 and an auxiliary anode 5 has a control source 11 of alternating potential impressed across the cathode and auxiliary anode so that current flows in one direction only between them and a condenser 7 thereby impresses a unidirectional control voltage on the grid 4. The transformer 11 is arranged so that in the half-cycle when the cathode is positive the secondary terminal connected to the grid 4 is negative. The condenser 7 is charged, current flowing from plate 8 to cathode 2, auxiliary anode 5 and plate 9. During the working half-cycle the negative charge on grid 4 and plate 9 leaks away through impedance 10 which is adjusted to control the time of starting of the current from cathode 2 to anode 3.

Abstract: 1,080,884. Vehicle driving gear. NIPPON KOKUYU TETSUDO. Feb. 25, 1966 [May 20, 1965], No. 8498/66. Heading B7H. Vehicle wheels 6, 7 connected to each end of an axle 11 are driven from a hollow shaft 3 surrounding the axle by means transmitting torques of different magnitude to the respective wheels. Arms 9 integral with one end of the hollow shaft 3 drive the wheel 6 through rubber bushes 4, and arms 9a detachably secured to the other end of the hollow shaft 3 drive the wheel 7 through rubber bushes 5 which provide greater resilience in the direction of wheel rotation than the bushes 4 so that less torque is transmitted thereby. The arms 9a may be connected to the hollow shaft 3 by bolts or by means of a force-fitted joint. The bushes 4, 5 each comprise a rubber ring (Fig. 4, not shown), bonded between steel rings and provided with holes which are aligned radially and circumferentially respectively when mounted in the wheels 6, 7. A gear 2 force-fitted on the hollow shaft 3 is driven through a pinion 1 by a motor 10 which is suspended by bearings 8 from the hollow shaft 3 and also by a " nose " (not shown).

Title: Electric locking and unlocking apparatus
IPC: G07C9/00
Filed: 1973-02-21
Abstract: 1376271 Electrically operated fasteners TOKYO MAGNETIC PRINTING CO Ltd 21 Feb 1973 [11 May 1972 22 June 1972 (2)] 8505/73 Heading E2A  Signals recorded on a magnetic cord are read out to a logic comparator circuit for comparison with a stored predetermined code signal, the circuit output being transmitted to a control device for controlling a fastening mechanism. A magnetic cord is fed into a read out magnetic device comprising two heads 1A, 1A', Fig. 1B, one to read out the code signal and the other to read out a clock code signal; both signals are passed through amplifiers 2A, 2B, 2A', 2B', and waveform shaping devices 2C, 2C' e.g. monostable multivibrators to a series-to-parallel converter circuit 3A. Here, pulses of the clock code signal causes successive pulses, or bits, of the key code signal to appear sequentially at respective parallel terminals of a group of flip-flops forming the comparator circuit 3B with a group of diodes, Figs. 4C, 4D (not shown), the diodes forming an AND, gate so that an output will be provided only if all the comparisons coincide between the parallel key code inputs and corresponding parallel predetermined code inputs, for a storage device 4A. The control device 5A Fig. 4E (not shown) comprises a relay actuated by the output signal to actuate transistors controlling a fastener solenoid, to change the state of the fastener (locking or unlocking). Removal of the cord from the read-out device deactivates the relay to complete the operation. Other relays are incorporated for manual operation of the fastener mechanism. Fig. 5 shows apparatus for providing an output signal from any one of a series of key cords. Here, the read out signal from the comparison circuit passes to a temporary storage circuit 22, and is then simultaneously sent out to parallel comparator circuits 24-1, to 24-5 each accepting a different predetermined code signal, the comparator outputs passing to an OR gate, to allow the one, if any, output signal, corresponding to a matching comparison, to the control device. The apparatus in Fig. 8 shows the avoidance of a plurality of parallel terminals by the comparison of a signal of a series of pulses, with a predetermined series signal (no series to parallel converter circuit). Part of the read-out signal is sent as a clock signal to a storage circuit 83 to trigger the predetermined signal. The comparator output passes to a coincidence storage unit 84 where a low constant signal is passed to an AND gate 85, if the signals coincide, or a high output signal is passed if they do not coincide. In the former situation, the AND gate 85 transmits a signal for fastener actuation, due to reception of an end of read-out signal from the storage unit 84.

Title: Improvements in or relating to superheterodyne receivers with automatic frequency control
IPC: H03J7/14
Filed: 1946-03-22
Abstract: 616,358. Automatic tuning correction. PHILIPS LAMPS, Ltd. March 22, 1946, No. 8921. Convention date, Aug. 16, 1941. [Class 40 (v)] A superheterodyne receiver has means to apply automatic frequency control to a filter which distinguishes the intermediate frequency from the sidebands, the filter comprising a resonant circuit having its damping reduced by back-coupling, and one of the two voltages used for frequency discrimination purposes being derived from this resonant circuit. The Figure shows the intermediate frequency portion of a receiver, in which the intermediate frequency energy supplied .from tuned circuit 5 is amplified by valve 20. The damping of sharply tuned circuit 19 in the output circuit of valve 20 is reduced by feedback from amplifying valve 24 through coil 25. A reactance valve 21 connected across circuit 19 is provided to modify the timing of this circuit to maintain agreement with the incoming frequency, the necessary control voltage being supplied from resistance 12, which forms the output circuit of the frequency discriminator circuit comprising diodes 9 and 10. The input voltages to the frequency discriminator circuit are provided by coupling circuit 8, which is also tuned to the intermediate frequency, to circuit 5, and by connecting the centre of the coil in circuit 8 via phase correcting network 27 to resistance 26 which forms part of the output circuit of valve 24. The two input voltages are arranged to differ in phase by 90 degrees, the discriminator circuit then operating in known manner, to produce the control voltage across resistance 12. Since tuned circuit 19 is coupled to coil 25, a large variation of the phase angle between the two voltages applied to the discriminator circuit will occur if the intermediate frequency changes. The output across resistance 26 is also applied to detector 7. The Specification as open to inspection under Sect. 91 also describes a receiver circuit in which the control voltage from a frequency discriminator circuit is used to control the current flowing through coils which are wound on the same cores as the coils of the intermediate frequency tuned circuits, whereby a variation in the intermediate frequency causes a corresponding change to be made to the tuning of the intermediate frequency circuits. This subjectmatter does not appear in the Specification as accepted.

Filed: 1928-03-24
Abstract: 290,156. Electroacuistic Ges. May 7, 1927, [Convention date]. Magnetic instruments; diaphragms.-A sound producing apparatus comprises a main diaphragm 2 associated with a secondary diaphragm 6 through a narrow airchamber, and an open-ended resonator 7 of whistle-type located with one end close to the centre of the secondary diaphragm. The resonator if cylindrical is of length equal to an odd multiple of a quarter-wave length of the tone to be transmitted. It may, however, expand in exponential form as indicated by the dotted lines. The secondary diaphragm is of reduced width at the centre so that the air chamber is of conical form. With electromagnetic exciting means as shown, a condenser C serves for partial phase compensation and is of such value that the natural frequency of the electric circuit lies above that of the mechanical system. The frequency of the exciting alternator W lies between the two resonance peaks of the mechanical system. The diaphragms and resonator may be duplicated on either side of a central magnet, the coil of which is supported by special coil carriers secured to the sides of the casing.
