Title: Binder having high solids content suitable - for granure printing sinks
Inventor: HANSEN DR OTTO
IPC: D21H19/58
Filed: 1968-12-24
Abstract: An aqueous anionic primary dispersion containing co-polymers of vinyl compounds with acrylates and/or methacrylates, as well as free carboxyl groups, is thickened by means of NH3 and the ammonium-salt of an acrylic acid/methacrylic acid copolymer, followed by concentration, at temps. up to 40 degrees C, to a water content of 20%, with stirring and optional application of a vacuum. The thickening agent used may be the ammonium-salt of polymethacrylic acid in presence of free NH3. Process comprises emulsion copolymerising styrene, an acrylate and/or a methacrylate in presence of methacrylic acid, adding aqueous NH3, and concentrating the mass to obtain a solids content of 80%. Use of the highly conc. binder ensures rapid drying of the printing paper when inks with high kaolin content are used.

Patent DE-2004195-A1 (DE)
Title: Two or three high rolling mill housing
Inventor: SIEGFRIED METZGER HANS
IPC: B21B31/02
Filed: 1970-01-30
Abstract: The housing is fitted with a pair of adjusting bolts for setting the distance between opposite building elements in which the rolls are mounted. The female windings into which the bolts fit are in the building elements and a pre-loading force is applied by a hydraulic cylinder positioned under the lower building element, the upper element being supported by the upper cross beam of each stand, which also carry the drives for the shafts for the adjusting screws. The upper cross beam of the roll stand may be connected with the stand in two alternative positions permitting the fitting of either three or two rolls. The connections are effected by pegs which are fitted parallel to the roll axes, the cross beams being separate and cap shaped. The resultant connection is hinge like. When they are clamped in the higher position, permitting three rolls to be fitted, the building element with the middle roll is clamped between the setting bolt pairs for the upper and lower building elements. When fitted at the lower level, the cross beam forms the supports for the building element with the upper roll of a two high roll arrangement. The lower rolls can be adjusted by the adjusting bolts actuated from the bottom.

Title: Sputtering thin films - to produce homogeneous coatings on cylindrical articles
Inventor: BARCHUDAROW EDUARD M
IPC: H01J37/34
Filed: 1971-08-05
Abstract: An article to be coated is located between the ends of two aligned tubes which comprise the anode of a gas discharge chamber defined by a cylindrical sputter cathode within a vacuum chamber, the anode tubes being located along the axis of symmetry of the cathode, along which axis the lines of force of a magnetic field are created to produce a low-pressure discharge causing sputtering material from the cathode to coat the portion of the article between the anode tubes. Since the article is located outside the zone of the high voltage gas discharge it does not influence the discharge conditions. A cylindrical article may be coated without having to rotate it.

Patent DE-2211882-A1 (DE)
Title: Disposal of plastic waste containers - by reprocessing
Inventor: SCHMIDT MAX
IPC: B29B17/00
Filed: 1972-03-11
Abstract: The containers are first clearly marked to differentiate the classes of polymer. They are then placed in a washing machine for cleaning, from which they are fed to slow-moving conveyors, one for each class. Each conveyor carries the articles to a disintegrator, where they are granulated. The material falls into a receiver attached to the hopper of an injection moulding machine where it is reprocessed. The system thus regenerates rather than destroys the material.

Title: Transverse cutter for hot strip rolling plant - has two rolls with cutters arranged above and below strip rotating oppositely
Inventor: NODA AKIRA
IPC: B23D25/12
Filed: 1973-06-15
Abstract: These rolls rotate through no more than a single rotation on cutting a length of strip while the strip travels between these rollers. The angle between the cutter for cutting the leading end and for cutting the rer end of the strip length is less than half turn. This arrangement ensures that each of these cutters passes through a cutting position regardless of whether a leading or rear end of the strip is to be cut. The cutters can be used also for cutting the leading end of the strip for trimming purposes without making a separating cut along the strip.

Title: Cushioned neck support for air bubble bath - has lateral flexibly fitted earpieces
Inventor: FRENKEL WALTER
IPC: A61F11/14
Filed: 1973-07-05
Abstract: Earpieces gently cover the ears owing to the weight of the head when this is laid against the neck support, to protect against noise and water spray. This enables the user of the bath to relax completely, undisturbed by the noise of the turbine, which is expensive to sound insulate. Water spray produced by the strong agitation of the bath water is also prevented from entering the ears.
Patent DE-2349520-A1 (DE)
Title: Foamed clay producing kiln - comprises a counter current main feed and an additional raw material feed into the burner flame
Inventor: BERGMANN KARL DIPL ING DR
IPC: C04B20/06
Filed: 1973-10-02
Abstract: The raw material is passed counter-currentwise through a horizontal rotary shaft kiln with an axial burner the flame from which may be suitably deflected by means of compressed air. There is also a separate feed of raw material of smaller particle size than the main stream, directly into the flame. This method permits closer control of the particle size and distribution of the foamed clay granules formed.
Patent DE-2354927-A1 (DE)
Title: Lead sheath for sound insulation of pipe line - has axial distance webs for concentric location of pipe
Inventor: REINERT MAX
IPC: F16L55/033
Filed: 1973-11-02
Abstract: To reduce the noise level of metal or plastic pipe lines which carry gaseous, liquid or granulated substances, a lead sheath is placed concentrically over the pipe. The radial distance between the two tubes, which is a function of the noise frequency, is maintained by axial webs which can be part of either tube. For increased insulation, polyurethen foam, mixed with a sound insulating substance can be used to fill the space between the tube and sheath. The lead sheath also provides an efficient fire protection.
