Title: Single matrix telephone exchange system - has multi-connection capability on single crosspoint row structure to reduce matrix size
Inventor: SONNEMANN MANFRED
IPC: H04Q3/62
Filed: 1980-09-26
Abstract: The single switching matrix is for small PABX etc. telephone installations providing internal connection between extensions and connection through to exchange lines. The size of the matrix has been reduced and has the extensions connected to the outlets. The tie lines and exchange lines are connected to the inlets. Extension-to-extension calls are routed over crosspoints in the same inlet row as connections between extension and external line (ExV), minimal additional, typically one, extra inlet row is provided for internal connections to prevent switch blocking. The total crosspoint count is calculated using the number of external connections and the sum of the difference between external and extension counts. Operationally, any extension (Tln1 ..Tln6) can be connected to another using an inlet row (Ltg1...Ltg3) which would also be used to connect an extension to an external line (ExV,Ltg1..Ltg3).

The template cutouts according to the invention render complicated computations of the perspective part images unnecessary. Stereo drawings that can otherwise be constructed only using mathematical aids become accessible in a simple way by tracing the cutouts. <IMAGE>
Patent DE-3143283-A1 (DE)
Title: Vice
Inventor: SCHLEGEL WOLFGANG
IPC: B25B1/22
Filed: 1981-10-31
Abstract: In a vertically adjustable vice which is guided by means of a carrying tube so as to be vertically adjustable and rotatable in a guide tube which can be clamped together by a clamping device consisting of two half-shells and in doing so firmly holds the carrying tube together with the vice in each desired position, a high frictional and clamping moment is achieved without extreme effort by the fact that the bearing face between the guide tube and the half-shells of the clamping device is smaller than the inner face of the half-shells. The substantially higher specific surface pressure achieved thereby results in a plastic deformation of the bearing face, so that the latter does not need to be worked in its diameter and nevertheless a high frictional moment is achieved. The reduction of the bearing face can be achieved by longitudinal or circumferential ribs in the inner faces of the half-shells, by metal or plastic strips inserted in grooves in the inner faces of the half-shells, by a deformable intermediate tube arranged between the half-shells and the guide tube and having a corrugated circumferential wall, or alternatively by the inner face of the half-shells having a polygonal cross-section. Alternatively, a support in the manner of a frictional lining can be attached to the inner face of the half-shells.

Title: Method of joining two thermoplastic housing parts with the inclusion of a movable part
IPC: B29C65/06
Filed: 1982-03-31
Abstract: Two housing parts of thermoplastic material, which together form a bearing, are, according to the invention, joined to each other with the inclusion of a part held movably with play in the bearing, which part is of a material which can be welded with the housing parts, in such a way that a vibratory friction welding method can be used and the movably held part is allowed a yielding movement corresponding to the vibration movement, at least in relation to one of the two housing parts. This can take place by an amount of play of the order of the vibration amplitude or by the bearing being designed for executing tilting movements about an axis parallel to the joining plane and perpendicular to the direction of vibration. A welding of the movable part with the housing parts can be avoided in this way, even if the bearing is in or at the joining plane or lies in the direct proximity of welding points. Even a welding of journal parts within the bearing which are formed on the housing side is possible if the welded joint is kept within a tapered journal section.

Title: Automotive rail vehicle for transporting large pallets
Inventor: MEURER GERHARD DIPL ING
IPC: B61G11/18
Filed: 1982-04-10
Abstract: This automotive rail vehicle is characterised by a special frame construction with folding down buffer beams and lifting platforms which are arranged over the bogies and permit the large pallets which are deposited above the rail element, for example in steel works and iron foundries to be travelled under, raised and transported. The lifting platforms which are arranged displaceably in swivel frames also permit the large pallets to be set down and picked up on both sides of the rail element in that the swivel frames are swivelled through 90 DEG  transversely with respect to the longitudinal axis of the vehicle and are secured at their ends by means of folding-out sustainers. The pallet can be moved on these swivel frames by means of the displaceable lifting platforms parallel to the rail element and set down next to the track. The boundary lines of the vehicle both in top view, side view and in front view lie within the dimensions or within the clearance of the spaces between the pallet sustainers. As a result, it is possible with this rail vehicle to store large pallets closely next to one another and one behind the other and above the rail element without additional loading and lifting devices at any desired site and to pick them up again.
