Patent DE-2625590-A1 (DE)
Title: Multished loom with rotary reed - is arranged so that reed disks are always between warp threads
Inventor: STRAUSS EDGAR
IPC: D03D47/26
Filed: 1976-06-08
Abstract: A multished loom has a rotary reed formed by a shaft on which disks sepg. the warp ends, are offset to one another along a spiral line, for propelling the shuttles carrying the weft. The projections on the disks which propel the shuttles and beat up the weft, are arranged relatively to each other in such a way that, during the working of the loom, the weft thread guided towards the edge of the fabric, runs steeply inclined towards it, whilst, behind the shuttle in the zone in front of the fabric edge, it runs straight. Parallel to the rotary reed, there is a guide for the weft built up from thin plates aligned to the disks of the reed. These form a comb with a channel for the passage of the shuttle. In the direction of rotation each reed disk has a succession, a projection for propelling the shuttle, a thread carrying slot, close behind this, a thread progressing flank joining on to the slot, a projection following this, which has the largest radius of the reed, and a shuttle supporting zone having the smallest radius of the reed, and extending round to the shuttle propelling flank. The angle between the thread carrying slot and the beating up projection is between 70 and 110 degrees. The relative positions of the rotary reed and the guides are such that, the shuttle rests with its long side turned away from the guide on the cylindrical section of the mantle of the reed. The normal saacing between the assumed straight line connection between the outlet and weft thread from a shuttle and the edge of the fabric on the one hand and the axis of rotation of the reed disks on the other, is smaller than the radius of the section supporting the shuttle. The shuttle cannot become trapped. No extra equipment is required to prevent faults since the disks do not leave the warp ends. There are no additional supports to cause excessive wear of the warp threads.

Title: Emulsifiable hydrophobising pastes for textiles - are based on fatty acid-modified melamine resins
Inventor: HOFFMANN MARTIN DIPL CHEM DR
IPC: D06M15/423
Filed: 1976-06-09
Abstract: Prepn of emulsifiable hydrophobising agents in paste form based on condensn products (I) of hexamethylol melamine hexamethyl ether,stearic acid and triethanolamine, mixed with paraffin wax. The stearic acid still present is neutralised with alkalis or organic bases and the stearate formed is left in as an emulsifier. Used for treatment of textiles in fabric form. The paste are storage stable and easily dispersed in water. The hydrophobic action is not adversely, affected, since the stearate emulsifier is destroyed by acetic acid used in the treatment bath. In an example, 85 parts (I) and 28.3 parts hard paraffin wax (melting range 56-62 degrees C) are stirred into a soln of 4 parts 50% KOH in 330 pts water at 70 degrees C to give a paste.

Title: Electric heating element - for indirectly heated cathodes with wire spirally wound around core wire
Inventor: ANIKA WILHELM
IPC: H01J1/22
Filed: 1976-09-16
Abstract: A heating element, esp. for use in indirectly heated cathodes of electron tubes comprises a straight wire, representing a core, around which a wire is wound in a helix. Core and helix can be made of the same metal, or they can have different resistivities, heat conductivities and dias. In an example, a spiral wire of half the dia. of the core wire and a pitch of 11/2-times the core wire dia., both made of W or W-Re, produced an element with a 14% lower resistance than the core wire alone. the surface area increased 300-400% and the difference between element and emission layer temp. was reduced by 35%, resulting in a much longer life. This new heating element has an enhanced mechanical stability. It is a simple operation to provide an insulating coating (alumina) for it and it has a greatly increased heat radiating surface area.

Title: Gas ion implantation is solids - by electric field across gas plasma between high tension electrodes
Inventor: FREY HARTMUT DR
IPC: G21F9/02
Filed: 1977-08-22
Abstract: Gases can be locked in a solid by applying a voltage between an anode and a cathode, made of the same solid, which transfers material from one electrode to the other. A high-frequency alternating electric field is maintained across the plasma of the gas between the two electrodes. This requires no complicated appts. and is a much more efficient way than the conventional method. During the reconditioning of nuclear fuels, the gases arising, with radioactive isotopes such as krypton and xenon, are locked in solid metals so that they can be stored with less difficulties.
