Title: Double-sided plasma treatment of strip-form material - involves forming spatially limited hollow cathode discharge low-pressure plasma in special treatment chamber with space limited by material being treated
Inventor: ENGEMANN JUERGEN PROF DR
IPC: B05D3/14
Filed: 1992-10-08
Abstract: The materials (6) are drawn through a device connected in a vacuum chamber (K) by means of a winding mechanism (8). The surface of the materials (6) is modified using a reactive or non-reactive low pressure plasma generated by h.f. or pulsed discharge. A low pressure plasma, which only burns locally in the area of the device (7), is generated using two hollow cathodes (1) connected to the two sides of the material (6). The cathode chambers (7) are designed such that their effective plasma passing openings (20) are closed on one side by the material (6) to be treated. ADVANTAGE - Has improved efficiency using simple system.

Title: Bonded zig-zag non=woven material - has two stitching stations to give variable stitching action on both sides.
Inventor: HEILMANN HORST
IPC: D04B21/02
Filed: 1992-10-23
Abstract: To produce a non-woven material in zig-zag folds held together by fibre stitching on both sides, the continuous material is held in sections above the needle plane by vertical, swinging folding grips, to be lowered into the movement plane of the extended needles. The material is shaped into a pile fold between the fold grips and the already-stitched row, bending out towards the needle extension direction. The needles, using the fibres gripped by the hooks, finish the stitch looping, laying and casting. The needles in the second row are moved for their points to pass through the folded and partially compressed material, close to the first bonded surface to gather fibres on retraction across the needle axis for gathering, looping, laying and casting. Also claimed is an appts. with the needle plane of the first stitching point (20) at an angle from the verticals to the material take-off direction. A swinging fold grip at the first stitching point (20), above the needle plane, is at an angle between the material feed (10) and the needle plane and moves across the needle plane with a laying and guide surface for the material. The laying surface intersects the material surface at a gap from the needle plane, and can be moved into the needle plane when the needles (23) are extended. USE/ADVANTAGE - The method is for the prodn. of a non-woven material, stitch bonded, in zig-zag folds. The system allows a variable bonding on both sides to give a structural bonding type and stability.

Title: Seal with deformable thickness - is formed by pressing tool before installation with different thickness areas to ensure bending moment remains unchanged for effective sealing.
Inventor: STECHER FRIEDHELM
IPC: F16J15/06
Filed: 1992-11-11
Abstract: Before installation the seal is deformed by a pressing tool so as to have the thickness which is desired and changes constantly over the sealing area when subsequently installed. The screw forces present in the installed state are distributed on the sealing face according to each relevant local function which is calculated or estimated through the deformation of the sealing surfaces of the components being sealed caused by the ensuing pressure distribution. This is added to a desired thickness distribution in the installed state. The pressing tool is made with this thickness distribution. The seal is imprinted with a pressing force lying generally above the screw force. The seal is then hardened. USE/ADVANTAGE - Improved long-term sealing function particularly for cylinder head seals in IC engines.

Title: Loading work station with panels from stack - applying first slider to remove pack partially from stack and second slider to convey this to work station
Inventor: NALDI VALTER
IPC: B65H3/24
Filed: 1993-06-03
Abstract: In a procedure for loading a work station (2) with packs (3) of panels, removed from a stack (5) and then slid across, the packs are pushed in a first step into a particular position by means of a slider (18).

Title: Monorail trolley with low overall height and short clearances
Inventor: FINZEL MANFRED
IPC: B66D3/18
Filed: 1993-06-30
Abstract: A monorail trolley (5) has a travelling gear (6) on which a total of four running rollers (14a...14d) are mounted. One of the running rollers is driven by a traction motor (7) which is fastened to the travelling gear in a laterally projecting position.

Patent DE-4324104-A1 (DE)
Inventor: BERTSCH-FRANK BIRGIT DR
IPC: C01B15/10
Filed: 1993-07-17
Abstract: In the prior art, sodium percarbonate is coated with compounds which produce a stabilizing action in order to increase the shelf life. There is a need for an improved, boron-free, coating for sodium percarbonate. Proposed by the invention is a particle coating containing sodium carbonate plus one or more optionally partly hydrated magnesium compounds, preferably magnesium sulphate, in a single coat or in separate coats. The coating preferably contains two coats. The particles are produced by spraying aqueous solutions containing the coating compounds on to sodium percarbonate in a fluidized bed and at the same time evaporating off the water. Their long shelf life makes particles coated in this way suitable for use in washing, bleaching and cleaning agents.

IPC: C21B13/00
Filed: 1993-08-07
Abstract: The invention relates to a process and an apparatus for the direct reduction of fine-grained iron ores in a horizontal reactor using a reduction (reducing) gas and a heat transport gas in a fluidised bed.   The actual reduction vessel comprises a horizontal fluidised-bed reactor (1) into which fine ore (F) is pneumatically introduced from below. The heated reduction medium (A') is blown under pressure into the reactor (1) via inlet plates (2). The heat necessary for the endothermic reaction is supplied via heat exchangers (3) to the reactor (1) at different temperatures and transferred to the fluidised bed. The heat is supplied in counter-current to the reduction medium. Fuel gas (B) is burnt in combustion chambers (4.1, 4.2) with air supply (C) to give a heat transport gas (D). In the downstream heat exchangers (5.1-5.3), the reduction gas (A') is preheated before it passes via the inlet plates (2) into the individual reactor zones (1a, 1b, 1c). Discharge of the iron sponge (6) and removal of the blast-furnace gas (E) is performed in reactor zone (1d). <IMAGE>
