Title: Dilation element for bridging over expansion seam in building structure - comprises flexible deformable sealing element formed as hollow profile rollable between plate edge strips which either overlap or are spaced apart
Inventor: SCHOOP TRAUGOTT
IPC: E04B1/68
Filed: 1991-02-21
Abstract: The dilation element consists of two plate edge strips (1.1, 1.11, 1.12, 3.1, 3.11) between which is a flexible deformable sealing component (5.1). The sealing component is connected to the plate edge strips by adhesive unions (7), and with the use of a rubber-type material for the sealing component, a vulcanisation seam-rubber-metal union can be used. When the material of the sealing component is not vulcanisable, a normal adhesive union (7) can be used. The sealing component is formed as a hollow profile which by means of the adhesive union is rollable between the plate edge strips. These strips, in common with the sealing component, bridge over a constructional or expansion seam. On account of heat expansion and shrinking in building structures, the plate edge strips are movable in their planes to and from one another. USE/ADVANTAGE - As a dilation element for expansion seams in building structures capable of absorbing considerable deformation.

Patent DE-4127610-A1 (DE)
Inventor: ELSER DIETER
IPC: B62D5/06
Filed: 1991-08-21
Abstract: The invention concerns a pressure cut-off device in the end positions of the steering lock in a power-assisted steering system. In steering systems with a working piston (2) which slide in the steering housing, this cut-off device is installed in a through bore (17) in the working piston (2). A cut-off valve (20, 22 or 21, 23) actuated by a ram (24 or 25) which strikes against a wall (30 or 31) is provided for each steering direction. To avoid time-consuming adjustment of the cut-off valves (20, 22 or 21, 23), bolts (40 and 41) with press-fitted bushing (32 and 33) which act as limit stops are screwed into the walls (30 and 31). After the power-assisted steering system is installed in the vehicle, the bushings (32 and 33) can be pressed automatically into the end position corresponding to the steering angle. To this end, after preliminary fitting of the bushings (32 and 33) on the bolts (40 and 41) and after the combination so obtained is screwed into the housing (1) with the front axle jacked up, the vehicle is first steered against the wheel stops without power, during which time the working piston presses the bushings (32 and 33) onto the bolts (40 and 41) to the extent required for cutting off the power. As the rams (24 and 25) of the cut-off valves (20, 22 or 21, 23) project beyond the working piston (2) by a distance "x", the power is switched off shortly before the wheel locks are reached.

Title: Book copying - using sepd cut pages for copying on both sides for re-binding with replacements for damaged pages
IPC: B42C19/00
Filed: 1991-08-26
Abstract: To copy, film and/or digitise bound and printed material, with pages between the covers, the pages are initially separated by cutting along the inside margin, parallel to left edge, to clear the spine and the binding. The pages are then copied, on both sides, separately and then collated and rebound. The newly printed pages, through copying, filming and/or digitising are bound into the new book binding, instead of the original sheets, with newly printed pages in the same format, or enlarged or reduced formats. The original pages are treated with physical, chemical or biological processes before rebinding, to protect them from damage and especially acid attack, without necessarily going through a copying, filming and/or digitising process. Damaged pages are replaced by copying or fresh printing on age-resistant paper. ADVANTAGE - The method gives a mass production operation to the copying, filming and/or digitising of bound material, and replace damaged pages especially through acid attack.

Patent DE-4212771-A1 (DE)
Inventor: VIEGENER WALTER
IPC: F16L19/06
Filed: 1992-04-16
Abstract: 2.1 A pipe screw union is intended to be constructed such that the sealing ring (15) is still subjected to deformation forces even when the pipe (16) is displaced in the axial direction and at the same time drives the clamping ring (14). 2.2 In addition to the clamping ring (14) and the sealing ring (15), the pipe screw union according to the invention also contains a compression ring (13) which engages over the outer wedge surface and that end surface of the clamping ring (14) which faces the sealing ring (15). When the cap nut (11) is tightened, the compression ring (13) transmits the forces to the clamping ring (14) and to the sealing ring (15). If the pipe (16) is moved away from the basebody (12) of the pipe screw union (10), the compression ring (13) sticks in its position so that the deformation forces act on the sealing ring (15) as before. As a result of the movement of the clamping ring (14), it is pressed against the pipe (16) with an increased force. 2.3 The pipe screw union according to the invention is particularly suitable for gas-tight connections. <IMAGE>
