Patent DE-3446903-A1 (DE)
Title: Precast concrete member between trench wall segments
Inventor: BARTSCH WOLFGANG
IPC: E02D5/18
Filed: 1984-12-21
Abstract: In a precast concrete member which is arranged as a stop element between segments of a trench wall, provision is made for the joint tape to be arranged in concrete at a section set back in concrete relative to a front section in the direction of the adjoining trench-wall section, the joint tape projecting in the direction of the adjoining trench-wall section at most as far as the front section. Thus reliable sealing of the concreting joints is achieved.

Title: Designation carrier for electric lines and injection mould for its production
Inventor: WILMES MANFRED
IPC: B29C45/00
Filed: 1985-03-28
Abstract: In the case of this designation carrier for electric lines, an upper carrier piece (1) is provided, onto which there are formed clamping clips engaging around the electric line in the form of narrow webs (4) which, starting from the one end face of the carrier piece (1), extend only over part of the carrier piece width. Such designation carriers are produced in a continuous length, joined together detachably by means of their catch connections (2, 3). These designation carriers form a pliable adaptable continuous length. They permit the production of an injection mould of a simple design, in which the rear side of the mould cavities can be partially bounded by a simple slide plate (13), which is able to be moved to underneath the part remaining free of the carrier piece (1) of the previously produced designation carrier and can fix the latter in its mould cavity bounding position. The sections of the walls of the mould cavity opening out on the moved-in slide plate (13) may be conically widened in the direction of the slide plate (13) in order to facilitate ejection. <IMAGE>

Title: Method for controlling a mechanical stress in a nut driver
Inventor: DONIWA TABITO
IPC: B23P19/06
Filed: 1985-06-19
Abstract: Method for controlling the mechanical stress for a nut driver with the use of a nut driver and an assigned control device. In accordance with the invention, the tightening torque Tf of the torque transmitter of a nut driver is stored in a middle position of a fixed first rotational angle  theta , contained in a middle region of the seat of a controlled screw on an object attached by screws to the final attached position of the screw. The motor of the nut driver is stopped in a position of a second rotational angle ( theta  +  alpha ) which is larger by a fixed value  alpha  than the first rotation angle. The motor of the nut driver is reversed at the second rotation angle ( theta  +  alpha ). A reaction torque Tr of the motor is stored at the position of the first rotation angle  theta . The ratio of the fastening torque Tf to the axial force applied to the screw is calculated using a difference between the fastening torque Tf and the reaction torque Tr at the position of the first rotation angle  theta . In order to fasten the screw with a stable required axial force, the motor is stopped at a fastening torque Ts which is obtained by multiplying a previous input target value FS of the required axial force by the calculated ratio.

Title: Urinary flow measuring device for urological investigations
IPC: A61B5/20
Filed: 1985-11-26
Abstract: Hitherto, measurements of the urinary flow have scarcely been carried out in basic medical treatments despite the ever-increasing number of relevant patients. The urinary flow measuring device described permits it to be used also in medical practices because it is easy to handle and involves little technical expenditure. It comprises a measured value transmitter which in turn comprises a motor-driven centrifugal element, the driving power of the motor being related to the mass flow of the urine, and a control unit which serves to supply current and to process the measurement signal. The measurement signal is recorded via a connected recorder or printer. The measured value transmitter can be inserted in every commercially available toilet pan, and due to this micturition is possible in the usual way in women and in men. There is no need for any assisting personnel.

Title: Pre-amplifier with high dynamic range and sensitivity
Inventor: TIMMERMANN C C PROF DR ING
IPC: H04B10/69
Filed: 1985-12-11
Abstract: In optical receivers which essentially comprise a photodiode (1) and a transimpedance amplifier (2, 3), it must be ensured in many applications that the transimpedance amplifier is not overloaded when the optical receive signal levels are high. According to the invention, an additional circuit is provided which contains a non-linear two-terminal network, e.g. a diode (7), with low capacitance and which increasingly feeds the direct current of the photodiode through the two-terminal network as the direct current level rises, thus reducing the latter's differential resistance, so that the AC output voltage of the optical receiver increases only to an insignificant extent when the optical receive signal levels are high and as the AC photocurrent rises. <IMAGE>

Patent DE-3610367-A1 (DE)
Title: Shut-off member for a pipeline
Inventor: HOFMANN WILLI
IPC: E03C1/042
Filed: 1986-03-27
Abstract: The invention relates to shut-off members for gas, liquid and steam pipelines in general and relates in particular to water taps. Water taps have a connection branch for screwing into the connection socket of the water line. Proper screwing in presents difficulties if, in the case of tight, not-over-strained screw connections, the outlet of the tap is not in the desired position, so that the tap has to be repeatedly unscrewed and screwed in again to change the thickness of the sealing material. These difficulties are overcome according to the invention by an insert as end piece (4) of the connection pipe (3), which can be releasably connected to the connection pipe (3) in any position turned relatively towards the connection pipe (3). As can be seen from Fig. 1, the end piece (4) is first of all connected to the pipeline. Its other, in particular conical, end (5) fits snugly into the actual tap piece (1), which can be fixed on the end piece (4) in any desired position of its outlet (2) by means of a cap nut (13). When the cap nut (13) is unscrewed, it supports itself against the orifice plate (14) and consequently automatically releases the tap part (1) from the end piece (4). For screwing in and unscrewing the end piece (4), use is made of a polygonal wrench which can be inserted into the flow channel (19) and fits with a form closure at (18). <IMAGE>

Abstract: In order to prevent the possibility of a high static voltage occurring between the detonating cables (15, 16) and the housing (11) of an electrical fuze, which high static voltage leads to the detonating element detonating, a further cable (17) is provided which is electrically connected to the conductive housing (11). All three cables (15, 16, 17) are joined to one another outside the housing, for example by twisting, and are thus short-circuited. The short-circuit is not removed until after the ends of the three cables have been connected to a test set (27) or a detonating unit. In the event of twisting, the short-circuit can be removed by untwisting. <IMAGE>

Filed: 1986-11-05
Abstract: A process for the preparation of ultra-low-density polyethylene, in which ethylene is polymerized together with at least one C4- to C8- alpha -olefin in the presence of a specific catalyst at a pressure of 200 kg/cm<2> or greater and at a temprature of 150@C or above. The polymer, which is produced still in the liquid phase, is separated off from the gas phase, which contains unreacted monomers, by at least one cooling treatment at reduced pressure. In this way, an ultra-low-density polyethylene is obtained. The unreacted gas is recycled into the reaction system. The composition of the monomer mixture and the cooling treatment under reduced pressure are described in greater detail. Interferences in the recycling can be avoided.
