Title: Device for a load-bearing unit
Inventor: GEBELIUS SVEN RUNO VILHELM
IPC: B65G7/04
Filed: 1981-08-28
Abstract: A device which facilitates the transportation of a load-bearing unit along a supporting bearing surface using a force acting in the intended transporting direction has a piston which is movable to a limited extent towards the bearing surface and has a cutout which is open towards the bearing surface and in which a spherical support part is arranged, which spherical support part is movable towards the bearing surface into a position projecting outwards beyond the piston. Formed in the piston is a channel which connects the cutout and the end of the piston opposite the opening of said cutout. An inlet to be connected to a source of compressed gas serves to feed the compressed gas to the end face of the piston opposite the cutout in order to move the piston and/or the support part into a position in which the spherical support part is in contact with the bearing surface. In this position of the support part, the gas can flow along the support part while it exerts an increased pressure on the region of the support part facing away from the opening of the cutout so that a lifting movement of the load-bearing unit is achieved relative to the supporting bearing surface. A valve member is preferably assigned to the channel, which valve member can limit the gas flow to the cutout when the spherical support part is in a position which is aligned and limited towards the outside by the piston without being in contact with the supporting bearing surface.

Title: Weighing device with wagon balance and evaluation and operating unit, especially for railways
Inventor: STRATMANN KLAUS ING GRAD
IPC: G01G19/04
Filed: 1981-10-02
Abstract: The invention relates to a weighing device consisting of a wagon balance and of an evaluation and operating unit. The weighing device is intended especially for the weighing of railway wagons. The wagon balance includes, in the basic construction, a balance bottom part, a weighbridge and load cells between the balance bottom part and weighbridge. Wheel-flange receptacles for the wheel flanges of a wagon to be weighed are connected to the weighbridge. Moreover, the weighbridge is seated by means of guide elements in the fishing surfaces of the associated rails. A multi-wire measuring and control cable leads to the evaluation and operating unit which is incorporated in the calibrating circuit of the wagon balance. The measuring and control cable is connected unreleasably to a distributor block of the balance bottom part. The distributor block is designed as an independent constructional part which has electrical contact elements and which can be inserted into a distributor-block receptacle having complementary electrical contact elements. A coupling lock having a lock cylinder is located on the distributor block. This lock cylinder has a coupling element retractable and extendable when the lock cylinder is actuated. The coupling element can be retracted into a coupling-element trap arranged on the distributor-block receptacle. The coupling-element trap possesses a monitoring switch actuable by the coupling element, so that the evaluation and operating unit can be activated only when this monitoring switch is correspondingly actuated. A key-guide device having a key fastened in it for the lock cylinder is located on the distributor-block receptacle. By means of the key-guide device, the key can be introduced into the lock cylinder and actuated. According to a preferred embodiment of the invention, the arrangement is such that, in the non-introduced position, the key is located in front of the lock cylinder as an introduction baffle against the actuation of the lock cylinder by a foreign key or tool. <IMAGE>

Patent DE-3241415-A1 (DE)
Inventor: BOENING WERNER ING GRAD
IPC: G06F13/00
Filed: 1982-11-09
Abstract: The data transferred between a data transmitter, for example a memory (MM), and a data receiver, for example a peripheral device (PL), is carried out by a DMA control (DMA) operating simultaneously in conjunction with a microprocessor (MP). For this purpose, the DMA control uses a channel program located, for example, in the memory (MM), which consists of transfer commands and control commands. The data transfer can be effected either in selector mode or in multiplex mode. Switching between selector mode and multiplex mode is determined by the content of a register placed in a mode register in the control device ( or DMA). If the data transfer is to be effected in multiplex mode, the choice is between byte/word multiplex mode or block multiplex mode. The operating mode in multiplex mode is determined by the transfer, and in the channel program. Thus, a data transfer can occur both in block multiplex mode and in byte multiplex mode over the same channel. The DMA control carries out the command initiation and the greatest proportion of the command execution in the case of byte multiplex or block multiplex mode in identical steps, only the number of bytes to be transmitted being different. <IMAGE>

Patent DE-3247659-A1 (DE)
Inventor: RUHRMANN WOLFGANG DR
IPC: G01D5/26
Filed: 1982-12-23
Abstract: An optical sensor is made of light transmissive material and has luminescent particles distributed throughout its volume. The luminescent particles are excited by a suitable type of energy, preferably light. As they return to their original state, they emit light uniformly in all directions. Depending upon the relationship of the index of refraction of the sensor body material to that of a test medium abutting a boundary surface of the sensor body, part of the luminescent light is reflected, the remainder passing into the test medium with a change in direction (refraction). When the test medium is optically less dense than the sensor medium luminescent light incident on the boundary surface at an angle exceeding the critical angle undergoes total reflection. For an elongated sensor body, this totally reflected part is transmitted to the end faces of the sensor, where its intensity constitutes a desired measure of a physical quantity. The sensor is effective for any physical characteristic which can change the index of refraction of the surrounding medium or that of the sensor itself. In addition, the quantity of totally reflected light can be varied also by changing the quantity of primary light applied to the sensor. Possible applications of a sensor of this type include measurements of liquid level in a container, the measurement of concentrations of a given component in a solution, temperature and pressure measurements of gases, monitoring of the boiling point of a liquid at very low temperatures, measurements of humidity, and a variety of position and length measurements. The sensor can also be used as a unit in a keyboard.
