Title: Disposal of asbestos-filled machines - by injecting foaming resin mixt. into interior where it spreads to all asbestos-filled pts. and allowing it to cure before suitable disposal
Inventor: WOLFF KLAUS
IPC: B09B3/00
Filed: 1990-08-06
Abstract: To make ready for disposal machinery etc. which is filled with asbestos a lance is pushed through at least one opening into an outer space in the equipment which is connected to the parts filled with the asbestos; foaming material is then injected through the lance and allowed to cure with foaming agent and accordingly spread into the parts concerned; when the foaming material reaches the asbestos zones and has cured the machinery is virtually filled with foam and is correspondingly sealed off. Pref. foams are polyurethane, polystyrene, polyethylene, urea/formaldehyde, PVC or copolymers. ADVANTAGE - The process can be used at the place where the machinery is installed. It is relatively inexpensive.  The machinery can be disposed of after the process and without any risk from residues and without polluting the environment.

Title: Computer controlled injection moulding to maintain isochore phase - by monitoring pressure and temp. valves against time and determining representing core of shot by computer
Inventor: WIPPENBECK PETER PROF DIPL ING
IPC: B29C45/76
Filed: 1990-08-24
Abstract: The process maintains the isochore phase when injection moulding thermoplastics. When the mould is filled with the shot it is subjected to a consolidating pressure and cooled at the same time, its specific vol. is maintained constant (isochore phase) by the pressure in the mould and the temp.  representing that at the interior of the shot. The pressure-temp. relationship is determined and imposed by a computer on to the machine controls. The temp. representing that at the core of the shot is determined by computer-supported observations plus analysis of the measured values against time during the process. ADVANTAGE - The procedure provides a representative temp. of the moulding by means of which the isochore phase of the process can be better controlled than by using the usual outer temp.

Title: Bending compensation roller - has oil forced out of secondary chamber by compressed air to reduce mass
Inventor: NISKANEN JUHANI
IPC: F16C13/00
Filed: 1990-09-24
Abstract: To reduce the power consumption required by a bending compensation roller, in a papermaking machine, pressure medium is removed from the sec. chamber (17), and compressed air fed into the chamber (17).

Then the distance between the drill point or the top side of the web (15) and the beam support (24) is measured by means of a displacement-measuring device (23) allocated to the vertical drilling spindle (11). The web centre plane (26, 27) or zero plane for the horizontal drilling spindles (18, 19) is then determined at each flange side of the I-beam (14) by subtracting half the web thickness. <IMAGE>
Patent DE-4211809-A1 (DE)
Inventor: GAFFAL KARL
IPC: F16J15/44
Filed: 1992-04-08
Abstract: The invention concerns a floating-ring seal in which the ring (4) is disposed so that it can move freely inside an annular chamber (6). Of the four walls (5, 7, 8, 17) of the chamber (6) enclosing the ring (4), two walls (7, 8) disposed at an angle to each other are stationary while the walls (5, 17) opposite them rotate at the speed of the drive. As a result of the freedom of motion of the floating ring (4) and the drive and braking torques acting on it through the walls (5, 7, 8, 17), the ring (4) rotates at a speed which is lower than the speed of the rotating components (1, 3).

Title: Spinning machine belt cleaning - utilising a split suction tube with the belt passing through the middle
Inventor: STANG BERNHARD
IPC: D01H11/00
Filed: 1992-08-11
Abstract: In the cleaning of a belt by means of suction, when fitted to a spinning unit, the belt moves through a split suction tube. The tube may be attached to the machine in a position where a nearby suction tube has already removed the lightweight fly. The tube is slit to allow the belt (1) to pass in the middle, and so is able to treat both sides of the belt. To remove attached debris, a brush may be fixed inside the suction tube, so that the belt runs over the bristle points. ADVANTAGE - The belt is cleaned in operation, and prevents dirt and fly returning to the spinning area, which would cause imperfections in the yarn.
