Title: Hydrodynamic-mechanical transmission more particularly for motor vehicles
Inventor: KICKBUSCH ERNST
IPC: F16H47/08
Filed: 1964-05-14
Abstract: 1,049,807. Hydro-mechanical change speed gear. KLEIN, SCHANZLIN & BECKER A.G. May 14, 1964, No. 20172/64. Heading F2D. A motor vehicle change speed gear providing reduced, direct and reverse ratios comprises a planet train 6 preceded by a hydrodynamic torque converter, the turbine T of which is fast with a sun gear 9 whilst the reactor L is connected by a one-way clutch 1 to an intermediate shaft 2 which is connected by a oneway clutch 4 to a planet carrier 6 and may be positively clutched thereto or braked by a clutch brake element 3 for reverse and low ratios respectively. Stepped planets 10 ... 12 mesh the sun 9, an output sun 14 and a reaction sun 15 which latter is held by a brake 16 for reverse. For low ratio the planet carrier 16 reacts through the one-way clutch 4 on the intermediate shaft 2 which is held by the clutch-brake element 3 whilst the turbine drives the output shaft. The carrier 6 may be bidirectionally held by a brake 5 to provide engine braking in low ratio. Direct drive is provided by engaging a clutch 7 to connect the planet carrier 6 to the sun 9 whereupon the planet gear rotates as a unit and the one-way clutch 4 overruns. For reverse ratio the intermediate shaft is clutched at 3 to the carrier 6 and the brake 16 is engaged. Since the planets 10, 12 are of equal size the turbine T is thus braked and the reactor L drives the carrier for reverse. A one-way clutch 17 between the torque-converter pump P and turbine T permits push starting. The clutch-brake element 3 at an intermediate position engages both the clutch and brake to hold the carrier 6 which together with engagement of the clutch 7 or brake 16 provides a parking brake.

Title: Improvements in or relating to devices for reading magnetically recorded coded information
IPC: G11B5/335
Filed: 1954-07-12
Abstract: 752,415. Magnetic recording and reproducing heads. PHILIPS ELECTRICAL INDUSTRIES. Ltd. July 12, 1954 [July 15, 1953], No. 20318/54. Class 40(2) A magnetic head for reading coded information, such as pulses on a magnetic tape, includes a core 2 with two magnetically identical parallel branches 4, 5 bearing coils a, b carrying an alternating current carrier wave which produces fluxes driving said branches 4, 5 into the non-linear part of their characteristic, the direction of such fluxes being in aiding relationship but cancelling one another in the main part of the core, whereby when a signal flux is scanned by the head a modulation of the second harmonic of the carrier wave is induced in a coil c for detection by a detector D, the detected signals being fed back to a coil d such that the signals are reinforced to an extent that instability occurs. When this happens a discontinuous transition in the hysteresis curve takes place, as from E to F and P to Q in Fig. 3, such transition being employed to produce the sharp transitions required when reading square peak pulses.

Filed: 1934-07-11
Abstract: 441,272. Inductor alternators; selfcontained supply systems. JOEL, H. F., 39, Beckenham Road, Beckenham, Kent. July 11, 1934, No. 20367. [Classes 35 and 38 (iv)] ] Variable-speed generators, with.-A train &c. lighting system employing storage batteries m includes a main alternator e and an alternating-current exciter f both of the inductor type mechanically connected together, rectifiers p, r being included in the output circuits of both machines, the arrangement being such that the exciter current varies the field of the main machine to maintain a substantially constant voltage from a given low speed. The resistance s in the exciter field circuit regulates the maximum voltage of the machine e in proportion to the speed of the set. Additional assisting field windings u, Fig. 2, may be provided in the main alternator fed from the battery m, the voltage being maintained substantially constant by reason of saturation and flux leakage. The resistance v is employed to vary the rate of charging of the battery. Alternatively, the windings u may oppose the separately exerted windings i. Additional shunt windings w may be provided in the exciter. The switch t may be dispensed with and the end of the alternator armature winding h connected to the battery and lighting circuits m, n through a rectifier and to the exciter winding k through a second rectifier. Residual magnetism in the exciter is relied upon for starting in this modification. In a further form, the rotor of the main alternator has half the number of stator teeth and these teeth are all of one polarity. As the speed of the set increases, the magnetic circuit of the main alternator becomes saturated and the consequent flux leakage causes the voltage to be maintained substantially constant. The Provisional Specification describes an. arrangement in which the main alternator is excited by the exciter only and the exciter is provided with a second field winding in series with the field coils of the main alternator, the exciter being fed by the accumulators so as to produce a differential effect on the main alternator field.
