Title: Locating faults in optical transmission paths - by feeding output of regenerator back via adjacent opposite-direction regenerator
Inventor: STACH RALF MICHAEL ING GRAD
IPC: H04B10/00
Filed: 1980-11-13
Abstract: The method involves passing the signal from a selected regenerator via a monitor loop to the input of the adjacent regenerator operating in the opposite direction and then back to the selected loop input. All circuit elements of the regenerators connected by the monitor loop are tested without the use of expensive optical loop switching or loading the transmission paths with additional damping. The light signal produced by the optical source (LD) at the output of the selected regenerator is converted into an electrical signal. The electrical signal is passed along a conductor (9) contg. a loop switch (4) and is converted back into an optical signal. The optical signal is fed to the optical receiver (OE) at the input to the adjacent regenerator.

Title: Car roof rack with loading device
Inventor: SCHACH ALFRED DR
IPC: B60R9/042
Filed: 1981-02-26
Abstract: The subject matter of the invention is the square or rectangular loading frame, which is arranged above the car roof, is mounted on rollers, is screwed and clamped to the roof channels, can be extended laterally, can be tipped downwards over one of the side panels of the car and can also take the form of a net, basket or other container. This loading frame permits material to be loaded by one person at ground level when it is in the tipped-up inclined position along one side panel of the car, and permits the material to be hoisted up onto the car roof without substantial physical exertion. This also applies to unloading. The loading and unloading device can also be used for bulky items, such as prams, tent devices, boats and bicycles or mopeds in a horizontal position. This makes it much easier to raise and secure material to be loaded on the car roof by means of a single person working from ground level.

Patent DE-3138667-A1 (DE)
Title: Method for pressure-grouting cracks in prestressed concrete members and pressure-grouting packer for carrying out the method
Inventor: HIRLER MANFRED
IPC: E04G23/02
Filed: 1981-09-29
Abstract: In conventional methods for pressure-grouting cracks in prestressed concrete members in the region of coupling points by injecting an injection resin into a grouting opening in the prestressed concrete member, either, in the case of low-pressure methods, the flow rate of the injection resin is relatively low, or it is necessary, in the high-pressure method, to employ greater pressures, which load the grouting packer inter alia. Furthermore, when using low-viscosity injection resins there is the risk of the injection resin coming out of the concrete member in the event of disruption to the grouting process. According to the present proposal, despite using a relatively low excess pressure a relatively high flow rate of the injection resin is achieved by creating, as a result of suction, a vacuum during the entire pressure-grouting process at a forced-ventilation opening arranged above the grouting opening. Consequently, an approximately constant pressure gradient is achieved between grouting opening and forced-ventilation opening. In the event of disruption to the pressure-grouting process when the sealing in the crack region is incomplete or when the injection process is to be voluntarily interrupted, only a small amount of injection resin, or none at all, can flow out of the crack region owing to the vacuum maintained in this case.

Patent DE-3205542-A1 (DE)
Title: Expansion engine
Inventor: VAZIRI-ELAHI MORTEZA DR
IPC: F01C1/20
Filed: 1982-02-17
Abstract: The invention relates to an engine, which is driven by the conversion of the potential energy of a high-pressure gas into kinetic energy. In the case of the expansion engine described here, the expansion chamber is arranged concentrically with the engine shaft, so that the piston located inside this can only move in a circle about it. The rotary movement of the piston is transmitted directly to the engine shaft by means of a lever arm. In order then to be able to apply the full gas pressure to the piston area in the desired direction of rotation, the expansion chamber is divided by a shut-off element. This shut-off element is, however, forced to open and frees the piston path each time shortly before the piston reaches it. The object of the invention is to detoxify the air which we breathe, especially in cities, by reducing or even completely removing combustion engine exhaust gases, in order to achieve the prerequisite for improved health and ecology. The engine, moreover, is small, uncomplicated, quiet in operation, environmentally friendly and cold.   <IMAGE>

Title: Method for error compensation in three-dimensional measuring and/or marking-out instruments
Inventor: MASUR KLAUS
IPC: G01B21/20
Filed: 1982-11-06
Abstract: A method for computerised error compensation of three-D measuring instruments is proposed, in which the deflection of the columns in two vertical, mutually perpendicular planes is measured by means of electronic spirit-levels and fed to a computer. The errors are determined from this in terms of angular tangent functions as a function of the transverse arm overhang length and the vertical distance thereof from the plane surface of the table per coordinate to a measurement point, and are logically combined by computer with the measured value for the purpose of correction. All errors are thereby taken into consideration, including temperature influences, errors in the drive system and other external effects on the instrument.
Patent DE-3244485-A1 (DE)
Title: Conveying device in the form of a turntable for objects such as bottles in a labelling machine
IPC: B65C9/06
Filed: 1982-12-01
Abstract: The bottles held between a rotary head and a rotary plate are each turned through at least 180 DEG  into the opposite direction by a drive acting on the rotary plate via a sliding coupling. During the first rotation, they are held in a certain rotational position by a holder. A sensor is used to determine whether this rotational position is the correct one or whether it is the rotational position after turning through 180 DEG . If the rotational position is still the result of turning, the holder is released so that the bottles can again turn through 180 DEG , until the holder once again stops them from turning further. The rotary movement of the bottles does not affect the rotary drive of the rotary plates which is necessary even for crown cap bottles. <IMAGE>

Patent DE-3244935-A1 (DE)
Title: Ink printing mechanism for office machines
Inventor: SICKING HEINRICH
IPC: B41J2/175
Filed: 1982-12-04
Abstract: In ink printing mechanisms it is necessary to feed ink to the printing head (9) continuously and to give early indication by means of an end-of-ink indicator that the ink reservoir (49) is becoming empty. Only in this way is it possible to prevent an occlusion of air in the ink supply system and to avoid faults in the formation of print characters. In known ink printing mechanisms, the end-of-ink indicator device is a component of the disposable ink reservoir (49), which makes the latter more expensive. The abovementioned disadvantages are avoided according to the invention in that an intermediate reservoir (47) is provided in the feed line (45, 51) between the pump (43) and the reservoir (49) which is arranged at a lower level than the reservoir (49) and has an end-of-ink indicator device. As a result, the ink reservoirs (49) are cheaper to manufacture and occlusions of air in the ink supply system can be reliably avoided. A uniformly high print quality is always ensured. <IMAGE>
