Title: Filter element - comprises folded filter medium incorporating thermoplastic spacers
Inventor: FRANZ ANDREAS DIPL ING
IPC: B01D29/01
Filed: 1990-12-06
Abstract: In a filter made of a long strip of a folded filter medium, the novelty is that the folded surfaces are kept apart by spacers; that the spacer surfaces are smooth and hemispherical; that the face of the spacer in contact with the filter medium lies flush and is glued or welded to the surface; that the spacer is applied as a viscous mass in droplet form which subsequently cures and hardens to a mushroom shape whose shaft penetrates the filter; that the other end of the spacer shaft receives a quantity of viscous material to form another spacer on the other side; that the spacers are arranged in a regular dot matrix pattern. A suitable filter medium (10) is folded and incorporates uniform rows of plastic spacers (2, 2'). Each spacer consists of a rod passing through the filter medium with a hemispherical head at each end. USE/ADVANTAGE - The spacers keep adjacent faces of the filter medium apart. The spacers are low-cost and cannot shift.

Inventor: RAETZSCH MANFRED PROF DR RER N
IPC: C08F2/50
Filed: 1991-09-30
Abstract: Photopolymerisable material consists of a substrate and light-sensitive coat(s) contg. polymer(s) (I) with salt-forming gps., ethylenically unsatd. monomer(s) (II) with complementary salt-forming gp(s)., a free radical initiator system and opt. other additives. The novelty is that a neutral (meth)acrylate (III) is added.

In an example, an unsubbed PET film base was coated with a soln. of a mixt. of 207 pts. alternating styrene/butyl half-maleate copolymer (mol.wt. 300000), 221 pts. methyl methacrylate/maleic anhydride copolymer (orginally contg. 12 mole % anhydride units, converted to the half amide 50 mole-% with NH3 and 50 mole-% with n-butylamine), 96 pts. N,N-dimethylaminopropyl acrylamide, 60 pts. methyl methacrylate, 7 pts. Michler's ketone, 38 pts. benzophenone and 33 pts. diphenyliodonium chloride in 2300 pts. MeOH and 560 pts. n-BuOH. After drying, the coating was 11 microns thick. Exposure and development by spraying with a 50:50 MeOH/water mixt. or water at pH 7.5-8 for 30 s at room temp. gave a translucent image with a relative scattered light intensity of 5%
Patent DE-4133799-A1 (DE)
Inventor: GUSSMANN ULRICH
IPC: C21D9/32
Filed: 1991-10-12
Abstract: The dimensional effect on quenching with pin or swage hardening tools is favoured and automatable both towards a closer tolerance on the final dimensions and towards a more flexible adaptability to larger variations in the raw dimensions in that there are at least two successive hardening stages (T1, T2) in shrinkage, the first of which takes place over a larger diametric range (6) and causes purely plastic deformation, while the second (T2) has to assume only partial plastic deformation. The tools involved are both fixed pins (5) with two diameter ranges (6, 7) and auxiliary force operable spreading pins (16) or corresponding matrices adjustable to smaller cylindrical dimensions during hardening. The risk of tool damage or structural breaks resulting from excessive shrinkage drops and the proportion of rejects within narrow final dimensional tolerances is reduced with a shorter and more economical plant running-in time with new workpieces.
