Abstract: A process for producing hermetically sealed filters (10) is disclosed. The process includes the steps of providing thermoplastic base (20) and top (30) filter parts and a section of filtration media (50), sandwiching the media (50) between sections of the base and top filter parts (20, 30) under a compressive force, applying a rapidly repetitive force to at least one of the filter parts (30) to cause movement between the parts and frictional welding of the parts, maintaining the compressive force after frictional welding to allow the melted portion of the parts (20, 30) to solidify and thereby form a fluid seal at the junction of the filter parts and at the junctions of the filtration media (50) and each of the base and top filter parts (20, 30). In one embodiment, the junction between the filter parts is the periphery of an automatic transmission filter, and the junction is hermetically sealed. A hermetically sealed automatic transmission filter is also disclosed.

Abstract: A multicomputer system comprises individual computers which communicate through two separate channels (K1, K2). If one channel fails, data transmission continues in single-channel operation through the remaining channel and errors in the data continue to be detected with higher redundancy. Each receiving computer (E) acknowledges reception of the transmitted data telegrams (A1.1(K), A1.2(K)), in the correct order, to the emitting computer (S). If the acknowledgement is not made or is incomplete, the emitting computer (S) permits, after an acknowledgement monitoring time, the repetition of the data telegram (WA1.1(L), WA1.2(L)), in which errors are detected with higher redundancy. If said data telegrams are received in the correct order and acknowledged by means of corresponding acknowledgement messages (Q1.1(L), Q1.2(L)) through two channels, the emitting computer and subsequently the receiving computer resume two-channel data transmission in which errors in the data telegrams (A2.1(K), A2.2(K); Q2.1(K), Q@.2(K)) are not detected with higher redundancy. As long as the computers have not yet permanently switched over to single-channel transmission of data telegrams and acknowledgements in which the errors are detected by higher redundancy, a time monitoring (TÜZ) for a maximal permissible time shift between the two telegrams of a pair of data telegrams or pair of acknowledgement telegrams is triggered on the receiving side of the data telegrams or acknowledgements with each first received telegram, at the expiry of which period the received telegram is rejected.

Abstract: A liquid tight rectangular paperboard container (10) is provided with a separate opening tab (17) secured to the top panel (15) thereof which enables the package to be opened to provide a fully open top. In particular, an elongate plastic window (18c) is formed along the front fold line (15a) connecting the top and front panels (15 and 11) of the package, and has ends (18d, 18e) connected to spaced apart arcuate shaped perforated lines (18a, 18b) extending to the rear corners of the top panel. In the construction of the package, the opening tab (17) is first ultrasonically welded to the outside surface of the package blank, and then the window section (18c) is pressed against and welded to the inside surface of the tab. A slit (40) which is formed in the window enables any air trapped between the window and the tab to escape during the welding operation. The package also includes a unique side sealing flap structure, while the particular paper supply roll from which the package is constructed has a unique structure. Also, a unique method of forming the package is disclosed.

Abstract: A method of laminating glass sheets (2,18), the method comprising the steps of: (a) providing a glass sheet assembly comprising a pair of opposed glass sheets which are spaced from each other and spacer means (6) located between the glass sheets, the spacer means being air permeable and liquid impermeable and extending along peripheral edges of the glass sheets, the glass sheet assembly being in a substantially horizontal orientation; (b) introducing a measured volume of a liquid laminating resin between the glass sheets so that the resin contacts the inner surfaces of both the top and bottom glass sheets as it is introduced into the space between the sheets, the introduction of resin being controlled so that a resin meniscus (42) between the top and bottom sheets spreads outwardly in a controlled manner; (c) filling the space between the glass sheets with the measured volume of resin, air which is displaced by the resin being evacuated through the spacer means; and (d) permitting the resin to cure and solidify thereby to form an interlayer between the glass sheets. The invention also provides a laminated glass article comprising a pair of opposed glass sheets which are separated by an interlayer of a cast-in-place laminating material composed of a cured plastics resin, the resin having been introduced between the sheets as a liquid having a viscosity of from 200 to 4000 centipoise, and an air permeable and liquid impermeable spacer means extending around the periphery of the article between the glass sheets. <IMAGE>

Abstract: The process for connecting two at least approximately mutually perpendicular pipe sections (1, 2) with different diameters serves preferably for connecting ladder rungs and ladder uprights made of stainless steel. The end of the thinner pipe section (2) is pressed through a shell bore of the thicker pipe (1) against the inner wall of the same so that the pipe end, of the thinner pipe (2), extending into the bore is upset. It is essential that the longitudinal extension of the upset part of the thinner pipe (2) is limited by cross-sectional change of the same. Expediently, a plug (4) having a conical section (6) can be used, which is introduced into the end to be connected of the thinner pipe (2) and is pressed through the shell bore of the thicker pipe (1) against the inner wall of the same. To limit the penetration of the conical part into the thinner pipe (2), the latter is locally deformed in cross-section and at the same time forms a slip-resistant foot rest. <IMAGE>
