Title: DC-to-DC converters
IPC: H02M3/338
Filed: 1979-03-20
Abstract: A DC-to-DC converter comprises a blocking oscillator form of circuit, with a transformer (Tr1) having a primary winding, a secondary winding and a feedback winding, with a switching transistor (T8) that has the primary winding in its emitter-collector path and that has its base activated by the feedback winding with a rectifier (D19) connected to the secondary winding, and with a resistance (R27) for initiating the activation of the transistor. A timer circuit (R28, R29, R30, R32, R33, C15, T7) connected to the feedback winding is provided to block the switching transistor after a predetermined time for a period while the transformer completely gives up its magnetic energy. The conducting period of the switching transistor is thereby controlled for better utilisation. <IMAGE>

Title: Feedback control for reduction of cogging torque in controled current ac motor drives and method
IPC: H02P27/06
Filed: 1978-07-18
Abstract: A decogging feedback control for current source inverter motor drives uses a change of instantaneous torque feedback signal with no dc component that is a function of only the instantaneous pulsating component of measured torque. The change of torque signal modulates the voltage applied to the dc link and therefore the dc link current to materially reduce the detrimental cogging torque pulsations and stabilize the motor, and can be switched out at a low frequency above which it is not needed so that the motor can respond properly to rapid variations in torque.

Title: Multiprocessor information processing system having fault detection function
IPC: H04Q3/545
Filed: 1980-04-15
Abstract: A multiprocessor information processing system has an additional function to detect a fault occurring in a processor. A counter is provided for each of a plurality of processors for holding an associated fault supervising code. The code stored in the associated counter is periodically updated by the associated processor while the update status of the code is supervised on a cycle longer than the cycle of the updating period. If a fault occurs in one of the processors, the fault supervising code corresponding to that processor will not be updated. Thus, the faulty processor can be detected by periodically supervising the update status of the fault supervising code. The supervising operation can be carried out by software or hardware.

Title: Zircon-containing refractories
IPC: C04B35/106
Filed: 1981-05-08
Abstract: Alumina-magnesia-chromic oxide refractory compositions yield remarkably stronger and less expansion- susceptible mouldings upon firing, when modified so they contain at least 1% by weight of zircon flour, and firing temperatures can be lowered or firing times reduced. An exemplary composition is a blend of particulate alumina, 35 to 97%, with 1 to 10% zircon flour, particulate magnesia and particulate chromic oxide, the latter two components being 1 to 10%; the percentages are by weight of the blend. Molten metal erosion resistance of the fired zircon-containing refractory is such that the compositions lend themselves to the production of orificed, metal teeming components.

Patent GB-2082330-A (GB)
Title: Eddy current surface probe
IPC: G01N27/90
Filed: 1981-08-04
Abstract: The eddy current probe for detecting flaws consists of two coils (14, 15) mounted coaxially within non magnetic housing (11) on non magnetic cores (16, 17) with each coil capable of separate axial adjustment. The coils are connected to the adjacent arms of an AD bridge circuit which can be balanced at the desired test frequency. The voltage output from the AC bridge due to lift-off or defects is the difference between the voltage change of each coil. The coils are adjusted axially by means of screws (21, 23) to provide a voltage output due to lift-off which is in the order of 90 DEG  with regard to the voltage output due to shallow defects making the latter simple to detect. A thin conducting shim (26) may be positioned between one of the coils (14) and the test surface in order to further rotate the lift-off signal of that coil. <IMAGE>

Filed: 1981-09-29
Abstract: A fuel pumping apparatus of the rotary distributor type has cam followers comprising rollers 21 supported by shoes 25 interposed between the pumping plungers 16 and the cam ring 22. Stop rings 26, 27 are provided to limit the outward movement of the followers and one of these rings is axially adjustable so that the amount of fuel supplied by the apparatus can be controlled. In order to provide reduced initial rate of injection of fuel the axial spacing of the surfaces on at least one of the followers which contact the stop rings, is smaller than in the case of the other plunger or plungers so that at the end of the filling stroke of the apparatus of the plunger associated with that follower will project outwardly further than the other plunger and hence will be moved inwardly before the other to provide delivery of fuel at a reduced rate. <IMAGE>
