Title: Magnetic recording material prodn. using imidazoline cpd. dispersant - giving increased packing density and remanent magnetisation
Inventor: BAUR REINHOLD DIPL PHYS DR
IPC: C09D5/23
Filed: 1977-10-01
Abstract: Prodn. of a magnetic-recording material involves dispersing finely-divided magnetically anisotropic material and usual additives in a soln. of a polymeric binder in an organic solvent, applying it to an unmagnetisable substrate, aligning the magnetic material with a magnetic field and drying and/or hardening. Improvement is that a 2-imidazoline cpd. of formula (I) (where R is 2-20C linear or branched (un)satd. hydrocarbyl; Y is OH or amino) is added as dispersant.

Title: Deburring ceramic mouldings, esp. handles for cups, etc. - using elastic tools pressing the burrs into the soft mouldings
Inventor: POELLMANN JOSEF ING GRAD
IPC: B28B11/18
Filed: 1977-12-07
Abstract: The tool consists of a carrier plate, for four profiled elastic segments (a) located on the inside and outside of a ceramic moulding consisting of two cup handles joined by a web. When pressure is applied to the segments (a), they are squeezed inwards against the flash formed by the joint line between two mould halves. The flash is thus pressed into the relatively soft moulding so it disappears. The rear surfaces of the segments are pref. supported by profiled steel strips so the segments (a) can only bulge in one direction, i.e. against the moulding. The segments are pref. made from layers of different elastomers, using a soft elastomer in the middle of the segments. Deburring cup handles of varying moisture content is achieved without distorting the handle.

Title: Breaking machine for substrates of thick-film components - uses two conveyor belts forming deformation hump to break score lines and deliver single chips
Inventor: SONST PETER
IPC: H05K1/03
Filed: 1978-04-15
Abstract: The substrate breaking machine consists of two conveyor belts (1, 2) one above the other. One belt moves in a clock wise direction and the other in an anticlockwise direction so that those parts lying parallel and adjacent are travelling in the same direction. Both belts are driven by rollers. The scored substrate (3) is placed on the lower belt (the longer of the two) and passes beneath the upper belt. A special roller (5) forces a section of the lower belt upwards along with a corresponding section in the upper belt so that a 'hump' is formed between the belts. As the substrate passes over this hump the resulting forces brake the substrate along the score marks.

Title: Low pressure die casting for non-ferrous metals - applying vacuum followed by finishing pressure
Inventor: LEIBFRIED DIETER DR ING
IPC: B22D18/00
Filed: 1978-04-27
Abstract: In a low-pressure die casting process, esp. for nonferrous metals, the cavities of the mould are first evacuated, pref. to a pressure of 0.1-0.9 atmos below atmospheric pressure. The molten metal is then pressed at a slow flow rate in the mould, followed by a finishing pressure of 2-10 bar (5-6 bar) applied to the molten metal in the riser. This allows even thick-walled castings of great density and complex configuration to be cast free from air or gas inclusions. It requires little equipment and produces nonferrous alloys of high purity which can be heat treated.

Title: Welding a PVC film bonded to textile fabric - esp. of thermoplastic chemical fibres, using high frequency field
IPC: B29C65/00
Filed: 1979-02-21
Abstract: A synthetic thermoplastic film, esp. of PVC, bonded to >=1 textile fabric of thermoplastic chemical fibres, is welded by the action of heat and pressure. To produce a welded seam at the edge of the product and shear through at the same time, the synthetic film is raised, where the weld is required, to the melting temp. of the fibres, esp. of PVC fibres. The pressing together of the film and the layer of fibres, has the effect of transferring the heat of the film to the fibres of the textile fabric. The heating of the film is brough about by dielectrical losses in the film in the high frequency field, or through the action of ultrasonic vibration. Method prevents the formation of frayed edges on the prods. and ensures that the shearing cut is correctly made.

Title: Water noise damper for domestic tap - has three part filter giving very little flow resistance
Inventor: ZWINK HELMUT
IPC: F16K47/02
Filed: 1979-04-12
Abstract: The one-way valve is specially for use with sanitary ware, with a valve-body containing a non-rotating porcelain disc and a rotatable, regulatory porcelain disc (2) lying in contact with the first. Both discs have openings essentially the shape of sectors of a circle (5, 6). A control organ (3) is in rotary connection with the regulatory disc (2) and has a diametric channel in it (8), which opens against regulator disc (2). A spindle (4) is in rotary connection with control organ (3) and extends out of the valve body through a seal. This provides a valve in which water noise peaks occurring at opening and shutting can be combatted without unnecessary reduction of flow. This is achieved by employing a three-winged filter (9) whose two outer wings (11) are laid like a band along the side walls of channel (8) and partly beneath the regulator disc's (2) openings (5, 6), and the middle wing (10) holding the two side wings (11) apart, allowing, in a central part, an undisturbed flow of water through openings (5, 6).
