Title: Envelope moistener with sponge -  has container with water sucked through aperture in intermediary wall
IPC: B43M5/02
Filed: 1990-09-26
Abstract: The moistener container contains a sponge and has an intermediary wall (2) with an aperture (3), together with two rollers.

Patent DE-4031546-A1 (DE)
Inventor: BOPPEL WOLFGANG
IPC: C21D9/38
Filed: 1990-10-05
Abstract: The invention concerns a process for the surface treatment of a texturing roller, an electron beam being used to produce a figured surface on the roller. In this process, before the roller is exposed for a certain period of time to an electron beam of energy density sufficient to produce a recess, it is exposed for a certain period of time to an electron beam of an energy density which leaves the surface structure essentially unchanged.

Title: Mechanical force generator - has hollow body, and slide, subjected to different pressures, resulting in energy
Inventor: HALLER KARL
IPC: F03G7/00
Filed: 1990-12-28
Abstract: The device generates a mechanical force, using a pneumatic pressure differential. It has a hollow body, at high internal pneumatic pressure which is sealed, apart from a lower slot-like opening. An automatically sealed trough with a downward projecting section, moves along the slot. A slide, coupled to a power transmission element, extends at an angle partialy through the hollow body, and through the trough, so that it is charged on its lower face by the high internal pressure, and partially forms the outer wall of the projecting section, thereby being charged by atmospheric pressure on the outside. Due to this, a resulting force component is created, which presses the slide axially into the hollow body, to supply energy to the power transmission element.

Patent DE-4115819-A1 (DE)
Inventor: SCHIMION WERNER
IPC: C10M175/04
Filed: 1991-05-15
Abstract: For treating fluids, interspersed with metallic and/or other material impurities, used for cooling and/or lubrication, in particular for separating off mill scale and oil-containing or grease-containing substances from the process water of open cooling circulations in the metallurgical industry, in particular in rolling mills, it is proposed to separate the coarse mill scale by means of gravity sedimentation from the contaminated process water, then to remove the medium-size and fine mill scale particles from the process water preclarified in this way, preferably by means of magnetic separation, and to separate the process water, finally clarified accordingly, by means of flotation into fractions which contain oil concentrate, water and very fine mill scale particles of low oil content; the clarified process water is re-used as coolant, all the mill scale separated off from the process water is smelted as sinter and the oil-containing concentrate is either discarded or subjected to spent oil reprocessing. It is also proposed to carry out this method in an appropriately designed treatment device.

Title: Coil-winding device incorporating two-part winding template - has gap between parts through which wire can be threaded for winding of next set of coils in opposite direction
Inventor: SENGER RUDOLF DIPL ING
IPC: H02K15/04
Filed: 1992-10-09
Abstract: The coil-winding device has a multiple winding template (1). For reversal of the direction of winding between two adjacent sets of coils, all wires (4) can be threaded between two parts (2,3) of the template.
