Patent DE-3915085-A1 (DE)
Title: Loom for three=dimensional fabrics - gives variable warp lengths and intervals with shapers to give material a durable form
Inventor: WULFHORST BURKHARD PROF DR ING
IPC: D03D13/00
Filed: 1989-05-09
Abstract: To produce a woven fabric in a three-dimensional form, the warps are drawn through with separate wefts with different lengths between them and at different intervals so that they can be varied after each weft insertion cycle. The gap between the weft/warp bonding points can be adjusted in the warp and weft directions to give a three-dimensional shape to the material as it leaves the loom, and keeps its shape without requiring subsequent moulding or profiling. The side interval for the warps is determined by a reed where the gaps between the blades are different from their upper to  lower edges so that, with height adjustment in aframe, the gap is set by the reed height setting. The blades of the reed can also have a side sliding movement to set the warp interval together or individually. The different warp lengths are determined by an intermediate shed and fabric take-off in a shaping mechanism through a multi-part lower shaper extended by a multi-part upper shaper.  The fabric edge section is brought to the required shaper and held firmly du ring the weft insertion while the separate parts of the shaper are raised or lowered as the material is developed. The shaping of the fabric edge section is formed by one or more rows of push rods., where each push rod can be raised and lowered independently to induce the required profile. The different warps lengths can be developed by a controlled suspension of the warps, singly or in gps. unlike conventional Jacquards, where the warps are moved in steps or steplessly to various levels above or below the mean central plane as required by the shaping. A weaving cycle includes two warp lifts with the first giving a constant raising and loweringg of the warps to form the shed for weft insertion, and the second phase is a different warp movement according to the three-dimensional shape while the inserted weft is beaten in. The variable warp interval can be set by the healds instead of the reed

Title: Engine lubricating oil filter
Inventor: MACK KLAUS
IPC: F01M11/03
Filed: 1990-07-17
Abstract: The engine lubricating oil filter has a housing with removable cover accommodating an annular element through which flow takes place in the radial direction. A passage delivers dirty oil to the element, while a drain passage from the housing leads to a collector vessel and is shut by a stop valve, being opened when the cover is released and the element removed. The stop valve (25) is contained in a cylindrical housing in which is a first valve plug movable in the axial direction and actuated by the element (18) via a balance spring and piston and working against a seat in the valve housing (10), so as to shut the drain passage (17) off.
