Title: Railway track tamping device
Inventor: CICIN-SAIN YVO
IPC: E01B27/16
Filed: 1981-10-08
Granted: 1984-09-27
Abstract: In a railway track ballast tamping device, a tamping unit is carried for vertical adjustment by a support mounted on the frame structure of a vehicle and comprises at least one pair of jointly-operating tamping tools crossing each other. The arm of these tools are adapted to pivot on opposite eccentric cranks formed on an eccentric shaft rotatably mounted in a bearing rigidly fastened to the support; the upper ends of the arms, opposite the pick-forming thereof, are each pivotally connected to a hydraulic cylinder inclined not in excess of 30 DEG  to the vertical; the planes passing through the axis of rotation on the eccentric shaft and the center of the opposite eccentric cranks thereof form between them an angle of 40 DEG  to 80 DEG  in order to warrant a symmetrical, synchronous oscillatory motion of the packers carried by the lower ends of the picks. To prevent the transmission of detrimental vibration to the support during the rotation of the eccentric shaft, there are provided, in addition to out-of-balance weight carried by a flywheel rigid with the eccentric shaft, balance weights fastened to the hydraulic cylinders and disposed above the level of the pivotal connections between these cylinders and the support. Furthermore, the tamping tools of a pair disposed on the same side of a tie have their upper ends rigidly interconnected.

Title: Forward converter switching at zero current
Inventor: VINCIARELLI PATRIZIO
IPC: H02M3/10
Filed: 1982-03-19
Granted: 1988-09-29
Abstract: A DC-to-DC converter processes power by a sequence of energy transfer cycles in each of which a quantum of energy is taken from a voltage source towards a current sink via a magnetic energy storage device (specifically a transformer having a small effective leakage inductance) and a capacitor. This (effective) LC circuit defines a characteristic time scale for the rise and fall of the current drawn from the voltage source so that a switching device connected in series with the source can be switched on and off at essentially zero current. Following each cycle the energy stored in the capacitor is released by the current sink. After the capacitor is discharged, the sink current is carried by a rectifier diode connected in parallel with the capacitor. This prevents the LC circuit from becoming a resonant circuit and leads to a unidirectional flow of energy from source to load which optimizes the efficiency and power density of the conversion process.

Title: Disc-shaped optically readable information carrier with protective rim
Inventor: TIEFENSEE VOLKMAR DIPL ING
IPC: G11B7/24097
Filed: 1984-06-15
Granted: 1987-12-10
Abstract: High storage density, optically-readable information carriers not only require a read-out side free of contaminants or dust for a faultless reading, but must also be protected against unintentional scratching when being handled on this side. For protection against scratches that usually occur due to dislocation of a disc deposited on its support, concentric elevations are provided that are structured under given conditions by clearances on the read-out side in the edge region and in the central region of the disc outside of the information structure which fills a concentric annular surface. The disc is able to slide on the elevations when deposited on the support without the annular surface, provided with the microstructure, coming into contact with the support.

Abstract: The feed shaft is inclined to compensate for friction in the pick-up. When the pick-up performs a jump to a desired position the inclination gives rise to a force acting with or against the linear feed motor (6). To avoid this influence a low frequency component of the tracking signal ST is held (15) and summed (17) to the feed signal SF applied to the linear motor.

Abstract: An solid-state electricity meter includes an electronic measuring unit with an analog/digital converter which receives signals from amplifiers for various measurement ranges, and a control section with a microcomputer wherein the meter signal is processed, taking into account correction factors for the various elements of the circuit. Each correction factor is a single value for each respective measurement range, and the correction factors for each range are contained in corresponding meter-characteristic quantities which are stored in the electricity meter. Each meter-characteristic quantity represents a measurement value corresponding to a specific quantity of energy. Only a few (e.g., only 4) meter-characteristic quantities need be stored in the electricity meter. These meter-characteristic quantitites can be determined in a conventional calibration procedure, and they enable all the fixed errors of the signal processing to be compensated.
