Patent AT-A217592-A (AT)
IPC: H02H7/122
Filed: 1992-11-04
Abstract: An arrangement for an inverter (1) that is connected to a d.c. voltage at the input end and that feeds an a.c. motor (2) is operated between a power choke (3) and a by-pass capacitor (4) at the input of the inverter (1). This arrangement consists of a recovery diode (5) in the blocking direction, to which the d.c. voltage is applied, and an antiparallel connection consisting of a semiconductor switch (6), particularly a disconnectable thyristor (GTO), and a diode (7) which is switched into the positive d.c. voltage line. The cathode of the recovery diode (5) is connected with the anode of the diode on one side and with the emitter or cathode of the semiconductor switch (6) on the other. Also included are a ammeter (8) and a voltmeter (9) which recognize an input short circuit, upon which the semiconductor switch (6) is blocked. This arrangement prevents overly high currents in the semiconductors (12) of the inverter (1) when an input short circuit occurs.

Title: Heating boiler is fed with solid fuel by transport worm - rotated by pawl-ratchet unit continuously driven via variable-throw crank
IPC: F23K3/14
Filed: 1983-02-02
Abstract: The mechanism is intended for adjusting the fuel feed of a solid fuel-fired heating boiler. The fuel is moved from a supply hopper to the combustion chamber by a transverse worm which is driven by a continuously rotating motor via a reduction gear. The output shaft of the gear drives the screw via a crank with adjustable throw which acts on a connecting rod to drive the worm via a pawl and ratchet unit. The amount of fuel fed per unit time is thus variable by altering the crank throw rod pivot radially adjustable in the crank slot.FL.

Abstract: ABSTRACT OF DISCLOSURE         Empty-load fluid pressure brake equipment for a rail-road car is disclosed.  An automatic changeover valve is operated by the pressure developed in the controlled outlet connection of a triple valve.  In the empty position of the changeover valve, a volume reservoir is placed in communication with the outlet connection and the pressure developed in that connection is sup-plied to the brake cylinder through a proportioning valve so that a brake cylinder pressure is developed which is a predetermined fraction of the cylinder pressure developed by the same brake pipe pressure reduction in the load position.  The ratio of cylinder pressure on an empty car to that on a loaded car is constant for all applications, and the volume reservoir is sized with regard to this ratio so that the equalization pressures are the same on an empty car as on a loaded car.  An initial opening bias is exerted on the proportioning valve so as to prevent proportioning action during the initial stages of brake cylinder pressure devel-opment.

Abstract: Abstract An improved magnetic tape test article includes a plurality of longitudinally spaced-apart test sections.  Some of the test sections are re-peated to facilitate recorder tests under different tape wrap conditions.  One of the tests is a compound test enabling several simultaneous measurements of several parameters of the recorder.  The tests are particularly adaptable for helical scan digital sig-nal recorders.  The tests measure parameters such as head to medium spacing, tracking (skew, servo offset and the like), readback circuit performance, including clocking, phase tolerances, error detection and cor-rection operations, response to dropouts, resynchro-nization response and amplitude tolerances.  Profile of the spacing between the record medium and the head is measured over the length of the recorded path around the cylindrical mandrel.

Abstract: MOTION  DETECTOR FOR WEIGHING SCALE               Abstract of the Disclosure A method of detecting motion of a weighing scale platform including the steps of periodically generating electric signals representing weight, transferring said weight signals to a memory, comparing said incoming weight signals with that previously stored in the memory prior to transfer of new weight signals, thereinto and generat-ing a motion signal whenever there are more than a pre-determined number of successive weight changes in the same direction.       An apparatus for detecting motion of a weighing scale platform including means for periodically generat-ing electrical signals representing weight on the plat-form and means for temporarily storing these weight sig-nals in a shift register.  The weight information is then transferred to a memory/display device.  A comparator device connected between the shift register and the mem-ory provides either a greater than, or less than output, and the output of this device is stored in a direction sensor.  A motion sensor is connected to both the com-parator and the direction sensor and provides an output whenever there are two successive weight changes in the same direction, i.e., when the comparator output and the direction sensor output are the same.  The output of the motion sensor is connected to a retriggerable multi-vibrator which provides a motion signal of predetermined time duration.
