Abstract: A deep-drawn screw cap of aluminum for glass bottles under internal pressure, where the transition area between the upper end face 1 to the lateral thread face 2 up to now was always evenly deep-drawn, now is to have at least one undeformed partial area 8. Because of this, sealing against the lateral edge 7 of the mouth is partially disrupted and a chance for the escape of gas is purposely provided in case the internal pressure in the glass bottle should rise too high. If required, a plurality of such partial areas 8 may be provided. In the deep-drawing device for a sealing head for the production of such screw caps the inner recess 12 should provide at least one partial enlargement 14 oriented towards the center axis 13 and extending approximately to the diameter of the preceding recess 11.

Title: User data display station.
Inventor: KRAUSE JOACHIM
IPC: H04M11/04
Filed: 1987-01-10
Abstract: In a user data display system, input information must be manually input by means of a keyboard (18) in order to establish a viewing connection. Individual input items of information are stored according to the invention in separate memories (38-52) that can be read out by a decoder (12) when a switch (22-36) is actuated. The switches are automatically actuated by a dialling device (54) actuated by an outer signal, for example the alarm signal from an alarm installation (62). A data display connection can thus be completely automatically established when the outer signal occurs, in order to indicate for example an intrusion to a receiving station.

Title: Process for preparing multilayer printed circuit boards.
Inventor: RUSZCZYK STANLEY J
IPC: H05K1/00
Filed: 1987-09-10
Abstract: Multilayer printed circuit boards are fabricated by preparing a first layer in conventional manner by forming a resist image on a copper clad substrate, etching away unwanted copper, removing the resist from the circuit pattern and optionally applying a dielectric mask such as conventional solder mask to selected portions of the circuit pattern. A second layer, and optionally one or more subsequent layers, are fabricated by providing an image of a second circuit pattern in a predetermined location on said first layer, the image being formed using a suspension of cuprous oxide in a curable resin material. The image is cured at least partially and subjected to chemical reduction to convert at least a portion of the cuprous oxide to metallic copper such that the unreduced cuprous oxide in resin serves as a dielectric layer. The image is then electrolessly plated with copper to build up the circuit pattern and the latter is selectively coated with a dielectric mask before repeating the cycle to build up one or more additional layers. Solder can be applied to selected areas of any of said printed circuit layers at any appropriate time during fabrication. The above method of fabrication has advantages of economy of time, materials and labor as compared with methods hitherto employed to prepare multilayer boards in which a plurality of single boards are fabricated individually and then assembled as a sandwich or laminate by application of heat and pressure.

Abstract: A device for cleaning pipelines comprises a casing (1) inside which, along its longitudinal axis, are mounted an inlet chamber (2) connected to a compressed-air source, a pumping chamber (4) intended to be connected to the pipeline and a piston (5). Two auxiliary chambers (6, 7) are mounted in the casing (1), separated from each other by the piston (5) provided with an air venting system. The first auxiliary chamber (6) is connected to the atmosphere. The second auxiliary chamber (7) is connected to the pumping chamber (4) through an air supply means provided inside a valve (14) of the pumping chamber (4), and to the inlet chamber (2) through a central passage (12) made in the piston (5). The cross-sectional area of the piston (5), facing the second auxiliary chamber (7) is larger than the end-face surface facing the inlet chamber (2), but smaller than the butt-end surface of an annular flange on the piston (5), facing the second auxiliary chamber (7). The casing (1) on the side where the pumping chamber (4) is located in the compressed-air discharge zone, is provided with through-passages (27), whose longitudinal axes coincide with the reactive force vector of the compressed-air flow.

Abstract: The apparatus has a tube (1) in which provision is made for the capacitance of a capacitor (2) placed in the flow and having an electric field determined by a first test voltage to be measured within one measurement cycle in a first measurement. At the same time the capacitance of the capacitor (2) depends on the composition of the flowing medium via its relative permittivity and polarisation. In at least one further measurement of the capacitance, a different test voltage is chosen, as a result of which the polarisation of the molecules of some of the components is altered in a controlled manner. This results in a set of linearly independent equations. To alter the test voltage, an ohmic resistor (5) in series with the capacitor (2) is shunted by a low resistance. <IMAGE>

Abstract: In a roll-shaped stator (2), a roll-shaped rotor (1) is rotatably mounted. They carry filtration surfaces (3) and collection chambers (5 and 6) respectively for the filtrate. A filtration chamber (4) in the shape of an annular gap is formed between the filtration surfaces (3). It can be charged under pressure with a suspension (8), and the concentrate can be discharged from the filtration chamber (4). To prevent homogenisation of the thickened suspension along the filtration chamber 4, the latter is divided into longitudinal sections (15), between each of which a vortex breaker point (16) is provided, for example in the form of a profile constriction of the filtration chamber. At this point, the flow structure formed in the preceding longitudinal section, as viewed in the direction of flow of the suspension, is destroyed so that a new flow structure forms in the next longitudinal section. This is particularly important if the filtration process is run in such a way that flow structures having Taylor vortices form. <IMAGE>

Abstract: The air-cushion space on the underside of a hover­craft is bounded at the front by a screen which is con­nected to the vessel via one or more pairs of arms placed above one another. Of each pair of arms, one can bend or buckle and the other either can bend or buckle or is rigid and hingeable at two ends. When the air-cushion snace is pressurized, the fixing points of the arms to the screen are located in front of the fixing points of the arms to the vessel. In this manner, optimum self-­adjustment of the screen is achieved.

When these communication cables consist of optical transmission elements, they must be protected from being pinched in the wire clamps when they are secured. The cross-section of the earth-wire overhead cable is designed so that a few steel wires in the stranded bond form a tension-proof and transverse-pressure resistant supporting structure, in whose clearance spaces communication cables, in particular optical transmission elements find space.
