Title: Pressure-tight seal for pipe connections on tank - has cap to prevent ingress of moisture during storage of tank before use
Inventor: VERHEYEN PAUL ING GRAD
IPC: B23K31/02
Filed: 1979-03-28
Abstract: During the transport and storage of the tank, the pipe connection (1) is closed via a sealing ring (2) pressed onto the end of the pipe by a cap welded onto the outer dia. of the pipe. When the tank is to be used, the cap is removed, so another pipe can be soldered or welded to the pipe connection.

The cap is pref. clamped on the pipe connection via a ring jg (4, 6, 7, 8, 9) while it is welded to the outer dia. of the connection. Heat exchangers, pressure vessels etc., are filled with a pressurised inert gas, e.g. N2, and sealed until they are ready for use. The seal prevents the leakage of the gas despite changes in ambient temp. from -30 deg.C. to +20 deg.C.

Title: Electrode for recording on metal coated recording paper - consists of aluminium or alloy with aluminium oxide layer giving good electrical insulation
Inventor: VOELKER WINFRIED DR
IPC: G01D15/08
Filed: 1979-08-14
Abstract: The electrode for producing recording tracks on metal recording layers on recording strips or sheets is coated with a very smooth layer of aluminium oxide giving very good electrical insulation. The layer occurs naturally because of the tendency of aluminium to oxidise and prevents the deposition of solids. The aluminium has a very high degree of purity, ie. 99.99 per cent. Alternatively, an aluminium alloy with silicon and/or magnesium may be used. Several electrodes can be placed in a comblike arrangement for multiple track recording. This type of electrode is partic. suitable for recording on metal recording paper contg. zinc and for use in slow printers. Vibrations caused by whiskers of metal dropping off are eliminated.

Title: Mechanical accessory for ultrasound mammography - has sound head on pivoted arm that oscillates beneath breast in water container
Inventor: IGL WOLFGANG DR
IPC: A61B90/17
Filed: 1980-11-07
Abstract: The accessory has a water container (21) with a cover (22) and a hole (23) with rounded edges. An arm (10) projects below the hole in the water container and carries a sound head (11) directed at the hole. The arm is pivoted to the container so as to execute a roughly semicircular oscillating motion about the centre of the hole. The breast fits into the hole. The end of the arm carrying the sound head can move perpendicular to the plane in which the arm oscillates. This is accomplished by making the head-end of the arm telescopic. The distance of the arm and therefore of the head from the hole can be adjusted. The arm may carry more than one sound head each associated with a different frequency. A video camera (19) may project through the container and look towards the opening in order to record the position of the sound head. Alternatively, the head is mounted on a semicircular bracket instead of on an arm. The bracket is pivoted at both ends. The patient's breast is examined almost entirely automatically.

Title: Process for the continuous production of a fleece of fibre particles and apparatus for carrying out the process
IPC: D04H1/736
Filed: 1981-01-07
Abstract: In an apparatus for producing a single-layer fleece from fibre particles mixed with a binder, there is a first endlessly rotating air-permeable conveyor band (10), onto the upper strand of which the fleece is deposited. Under this upper strand is arranged a vacuum device generating a vacuum zone and intended for the compacting and/or felting of the fleece, there being provided in this region above the upper strand an evener member engaging on the fleece and intended for equalising the latter. The region of engagement (15, 33) of the evener member (14, 31) is located outside the region of the vacuum device (20) encompassing the upper strand (10) of the first conveyor band (6). The vacuum device (20) is subdivided into at least two zones (21, 22) which are controllable independently of one another and which extend transversely relative to the direction of transport (11) of the fleece (42). A discharge conveyor device (35) for the fibre particles (41) occurring in the region of the evener member (31) and/or loose is also provided. <IMAGE>

Inventor: HAMMLER HARRY DIPL ING
IPC: A63F7/24
Filed: 1981-01-29
Abstract: At the edge of the playing field (3) of a table-top game, a shooting device (1) for the tangential discharge of balls (5) onto the playing field is provided.

IPC: E01C23/088
Filed: 1981-02-06
Abstract: The invention relates to the integration of the hydraulic tank into the hydraulically driven grooving assembly so that tank and frame form one constructional unit. By this means, simpler mounting and dismounting of the grooving assembly on the carrier vehicle is possible, production of the grooving attachment is less expensive, the weight of the grooving device is increased, and the space for a hydraulic tank on the carrier vehicle is saved. An exemplary embodiment of the invention is illustrated in the drawing and is described as follows. The hydraulic oil tank (1) is integrated in the grooving assembly and forms with the retaining frame of the grooving roller (2) one unit on which the connecting piece to the carrier vehicle (3) is also mounted, as well as the oil cooler (4) and other hydraulic assemblies. The grooving roller (5) is inserted underneath the oil tank in the retaining frame and is driven by a hydraulic motor (6). The grooving depth and the angle of inclination of the grooving roller are adjusted by steering wheels (8) which are height-adjustable by means of hydraulic cylinders (7). The grooving assembly is raised and lowered by means of the hydraulic cylinders (9). The hydraulic cylinders are secured on one side on the hydraulic oil tank and on the other side on a rocker (10) which is connected to the axle of the carrier vehicle via axle stirrups (11). <IMAGE>
