Patent DE-3719919-A1 (DE)
Inventor: GRAF REINHARD DR
IPC: A61B8/14
Filed: 1987-06-15
Abstract: The ultrasonic transducer (2) comprises an ultrasonic transmitter (8), in particular a linear array, with which it is possible to carry out a line scanning of the object (4) under examination. The ultrasonic transmitter (8) is mounted in a holder which, according to a first embodiment, is designed as a U-shaped and freely movable holding frame (14). The legs (16, 18) of the holding frame (14) are designed as hand grips. The ultrasonic transmitter (8) is arranged between the legs (16, 18) of the holding frame (14). Upon activation of a trigger mechanism (36), the transmitter can be pivoted about an axis of rotation (26) which lies parallel to the legs (16, 18). The pivoting range can amount to, for example, 60 DEG  or more. The pivoting is effected by a drive mechanism (30), which can be designed, for example, as an electric motor or as a mechanical spring mechanism. Upon pivoting, the ultrasonic transmitter (8) is turned relative to the holding frame (14); during this, the two legs (16, 18) of the holding frame (14) are held securely by the operating personnel. During the pivoting, images of various scanning planes (x, y) are recorded by means of the connected echo field recording device. According to a second embodiment, the holder is designed as an annular main body (40) which has hand grips (46, 48) and is closed off at the end by a membrane (42, 50). In this case, after the triggering, a sliding movement of the ultrasonic transmitter (8) directly on the object (4) is prevented. The ultrasonic transducer (2) is particularly well suited for the examination of the hip joint of restless patients, in particular for the preventive medical examination of neonates. <IMAGE>

Patent DE-3737591-A1 (DE)
Title: Screw/dowel combination
Inventor: EISENBERG HELMUT
IPC: F16B23/00
Filed: 1987-11-05
Abstract: The disadvantage with known screw/dowel combinations is that, as a result of large thread pitches, the tightening torques are relatively high and, as a result of large tolerance values, the tightening torques diverge to a very great extent. Although, in the case of other known combinations, a uniform tightening torque is achieved by a complex structure, said screw/dowel combinations are very expensive to produce and cannot be exchanged with the known plastic screwed dowels. The novel screw/dowel combination makes it possible for uniform, low tightening torques to be achieved and for the combination to be exchangeable and compatible with the former system.   In the case of the novel screw/dowel combination, the fastening element is a commercially available threaded rod (2) which, on its portion located within the dowel, exhibits a deformation (2a) for fixed anchorage in the dowel (1). The plastic dowel (1) is fixedly connected to the threaded rod (2) by being injection-moulded around it. The screw/dowel combination is preferably used for the fastening of rails. <IMAGE>

Title: Eliminating hydrogen from a post-accident atmosphere of a nuclear power station
Inventor: WIESEMES JOHANNES DR
IPC: G21C9/00
Filed: 1987-11-24
Abstract: In the reactor accidents in Three Mile Island and in Chernobyl, explosive hydrogen-oxygen reactions occurred prematurely. During accidents of this type ionising beams dissociate from the fission products molecular hydrogen, which collects in the gas space as a result of metal-water reactions, to give highly-reactive atomic hydrogen, which can directly react explosively with oxygen, whereby the safety container can fail prematurely. Previously known hydrogen recombiners - for example contact catalysts or sparking plugs - reduce the hydrogen concentration in the safety container only very slowly and are only effective in their direct vicinity. Furthermore, these recombiners, instead of recombining the hydrogen as planned, can actually unintentionally trigger a premature hydrogen explosion or detonation. In the case of contact catalysts it can occur that the finest particles of catalyst material can be detached from the actual catalyst by mechanical or thermal loadings. A sufficient heat dissipation is then not present. At high hydrogen throughputs these particles can be heated to red-hot temperature (as in the historic Döbereiner firework) and unintentionally trigger hydrogen explosions just like the sparking of the sparking plugs. The invention presented here allows the hydrogen concentration already to be reduced rapidly in the gas space. For this purpose the hydrogen is fed specially to ... Original abstract incomplete.

Title: Valve for an air conduit simultaneously used with a water conduit
Inventor: MATEJA ERNST
IPC: E21C35/22
Filed: 1988-01-29
Abstract: A valve for an air conduit (21) which is simultaneously used with a water conduit (6, 6', 57) and can be released by the pressure in the water conduit (6'), has the following construction: A closing element (22), which, in the closed condition, is pressed onto an annular valve seat (24) and, in the open condition, is flowed around by the air, is arranged on a hollow holding and moving body (27) through which the air flows in the open condition. By virtue of a step, this body forms a piston (35) in the valve housing (1, 2), which is likewise stepped (30). On the side facing the closing element (22), the piston delimits an annular cylinder space (33) connected to the water conduit (6, 6', 57) and, on the other side, is acted upon by the air pressure and also by a compression spring (9). The valve is favourable in terms of flow and can therefore be of small construction and be integrated into a plate or a block of solid material. This makes it easier to combine with complementary valve arrangements (4 and 3) which shut off the water conduit even if the air pressure or back pressure fails due to faults. <IMAGE>
