Abstract: The invention relates to a method and appratus for improving the running qualities of a rail vehicle bogie (4) which is provided with a plurality of individual wheels (11, 12, 21, 22) whose travel motors are fed on a wheel-unit basis by means of two open-loop and closed-loop control devices (6, 8). According to the invention two wheel-unit speeds (n1, n2) are determined from the wheel speeds (n11, n12, n21, n22) obtained, from which wheel-unit speeds (n1, n2) an actual value ( DELTA n) of the wheel speed difference is formed, which actual value ( DELTA n) is adjusted by means of a manipulated variable ( DELTA m*) to a desired value ( DELTA n*) of the speed difference, as a result of which a hand throttle desired-value (m*) is increased and reduced by this manipulated variable ( DELTA m*). In this way, the wheel units (1, 2) are given a speed difference which is permanently adjusted and corresponds to the radius (r) of a bend, as a result of which the running behaviour in bends is significantly improved because the pitching condition is fulfilled. <IMAGE>

Abstract: The invention provides a method of installing an insert in a plastics body so as to provide a screw thread therein, the insert being of metal and formed with the screw thread, and in which the hole in the plastic which receives the insert is sealed, by providing the insert with an 'O' ring located in an external peripheral groove and projecting therefrom, the size and shape of the insert and hole being related and selected so that in axial displacement of the insert into the preformed hole accompanied by softening of the plastic caused by the fastener being preheated or by vibrations applied to the plastic via the fastener as it is inserted, the 'O' ring only comes into contact with unsoftened plastic and only comes into contact with plastic towards the end of the axial installation movement. This ensures a good seal between the 'O' ring and the plastic.

Abstract: A circuit for filtering the ripple in an output of a multi-phase alternator in a vehicle system having a regulating circuit (24) that regulates the output of the alternator includes a switch (20) connected in series between a system voltage (21) and the regulating circuit (124), and means for closing the switch at a predetermined phase of the voltage of at least one of the stator windings of the alternator. The means for closing the switch (20) operates to close the switch (20) at a conduction switchover point among the stator windings in synchronism with a voltage waveform of the at least one of the stator windings, and is timed to produce an aliased waveform for application to the regulator. The output of the switch is applied to an integrator for integrating the output voltage from the alternator during an entire time cycle period of one of the windings of the stator coils for application to the regulator.

Abstract: A combination electric motor and transmission unit device has two inputs and a rotational mechanical output, at least one of the inputs being of electrical power, to a corresponding integral combination of an electric motor means with a transmission means. The directions of rotation and the rotational speeds of the two inputs can be controlled to provide the mechanical output at any desired rotational speed with peak power output, depending on the controls, thus providing an ideal infinite speed device. The device employs a novel arrangement of a differential unit or a planetary gear unit. The combined motor and transmission device is lightweight, requires a small number of moving parts, and is useful in vehicles powered by electricity, including for regenerative braking. Another embodiment of the drive device is useful for a flywheel for peak power supplementation and also regeneration.

Title: Switching arrangement with transistors.
Inventor: JERFY FRANZ
IPC: H03K17/732
Filed: 1992-05-19
Abstract: Two bipolar transistors (T1 and T2) having complementary sequences of zones are interconnected in such a way that the collector of the pnp-transistor (T1) is connected to the base of the npn-transistor (T2), whereas the collector of the npn-transistor is connected to the base of the pnp-transistor. A diode (DD), preferably a Schottky diode, prevents the saturation of both transistors at the same time in their interconnected state. This arrangement is particularly suitable for quickly switching electric currents and voltages, in particular in capacitive and ohmic loads, or for quickly reversing the charge of capacitances. Several variants that allow the circuit to be easily controlled, as well as composite structures such as half-bridge and bridge circuits for bipolar switching applications, are developed from the basic circuit.
