Title: Chain guide
IPC: B66D3/12
Filed: 1989-03-17
Granted: 1990-05-10
Abstract: The invention relates to a chain guide for a chain of a chain tackle (chain hoist, chain pulley block) in a housing, which chain is guided via a driven chain wheel, the lateral guiding parts of the chain guide having, for the stationary chain links, guiding projections which reach beyond a drive shaft and are adapted to the arc of the chain except for an insertion gap which is wider than the groove base diameter of the chain wheel. To avoid hitherto known disadvantages and achieve an optimum arrangement, it is proposed that the guiding projections (6) be interconnectable via an upward-tiltable bridge (7) which on one end is mounted on a hinge pin (8) and on the other end engages by way of a downward-open clamping opening (10) over a tension pin (9) arranged on the other guiding projection (6). <IMAGE>

Title: Pulse echo level measuring instrument with pulse transceiver - has circuits to derive distance between transceiver and reflection surface from time between single or multiple echo pulses
IPC: G01F23/296
Filed: 1992-02-14
Granted: 1993-06-24
Abstract: The instrument has a pulse transceiver and an analyser comprising a pulse transit time measuring circuit and a store to determine the distance between the transceiver and the pulse reflection surface from the pulse transit times. A multiple echo detection circuit compares a set point with the received echo pulses and transmits the transmit time between two echo pulses to the store. If multiple echo pulses are present an AND element activates a switch to connect the store to the analyser so that the distance between transceiver and reflection surface is derived from the stored time between two multiple echo pulses. USE/ADVANTAGE - Level measurement in containers, storage areas, open channels etc. Improved accuracy at very small distances between pulse transceiver and reflection surfaces.
Patent DE-4208777-C1 (DE)
IPC: G06F1/00
Filed: 1992-03-17
Granted: 1993-05-06
Abstract: Write protection circuitry for external mass storages aims at preventing accidental modification of data and programs by destructive software or incorrect operation of the computer, thus avoiding infection by computer viruses. Allocating units of the mass storage may be protected by means of a controller before writing and formatting operations. The controller only allows the protected allocating units to be written on when the operator has identified himself by a user-specific action that cannot be generated by any program. In addition, the protection conditions for the individual allocating units may be flexibly changed.
