Patent DE-2436961-A1 (DE)
Title: Vinyl aryl/rubber graft copolymers - from suspensions contg. calcium orthophosphate/carbonate and sodium alkylsulphate stabilisers
Inventor: BALLOWA GALINA DMITRIJEWNA
IPC: C08F279/02
Filed: 1974-07-31
Abstract: Impact-resistant graft copolymers of styrene or vinyl toluene (I) with synthetic rubber (II) are prepd by dissolving (II) in (I) at is not >80 degrees C adding softening agent (III) and mol. wt regulator (IV) and heating at 85-125 degrees C to 25-40% conversion of (I), suspending 1 wt pt. of this prepolymer in 0.3-0.6 wt. pts water contg. 0.15-1.5 wt. % Ca3(PO4)2 and 0.003-0.02 wt. % wetting agent (V), adding 0.15- 0.35 wt. % CaCO3 whilst heating to 90 degrees C, and continuing heating in stages to higher temps to complete the polymerisation. (II) is e.g. polybutadiene, polyisoprene, polybutadiene/styrene (III) is vaseline oil or butyl stearate. (IV) is e.g. laurylmercaptan. (V) is Na salt 8-18C alkylsulphate. Use of Ca3 (PO4)2, (V) and CaCO3 as stabilising system for the oil-in-water type of suspension formed for final polymerisation is novel. The copolymers are used for moulded components used in transport industry, housing and parts of radio and television receivers, refrigerator parts, packagings for fruit and foodstuffs. The special stabiliser system permits higher polymer, water proportions during polymerisation hence higher mfg. efficiency, greater yields from plant units, lower waste water and associated contamination problems.

Title: Automatic fitting seat belt for car - with door mounted fittings and security bolts between door and frame
Inventor: HOFFMANN GUENTER
IPC: B60R22/04
Filed: 1974-08-27
Abstract: The automatic fitting lap diagonal seat belt system has two mountings on the rear edge of the door and one central mounting.

Title: Flexible printed circuit manufacturing process - involves floatation bath for photosensitive layer development and for removal
Inventor: MITTERHUMMER GERHARD DIPL ING
IPC: H05K3/40
Filed: 1974-09-27
Abstract: A process for the manufacture of microminiature wiring on a flexible and insulating substrate is used in the preparation of wiring for semiconductor devices. A thin metal layer is laminated onto the substrate. The laminated sheet is then covered on both faces by a photosensitive lacquer. The photosensitive layer on the metal is exposed and developed using a floatation bath with directional flow at its surface. A chemically resistant layer is then applied on the exposed metal provided for terminations. The photosensitive layer on the metal is then removed by exposing it to another floatation bath also with directional flow at its surface. The floatation baths contain an alkaline solution and one tank may be used for both baths.

Patent DE-2514357-A1 (DE)
Title: Dowel pins for furniture panel assembly - have inclined locations to provide self locking linkage
Inventor: SHIMIZU TAKESHI
IPC: F16B12/24
Filed: 1975-04-02
Abstract: When assembling vertical and horizontal furniture panels dowel pins are used to link the components together. By orientating the dowels at an angle of about 45 deg. in the vertical panels, the horizontal panel will be held in position by gravity. To locate panels in a horizontal plane, such as shelves in a wardrobe, the vertical back panel will retain the shelves in position so that they can not be disengaged from the dowel pin locations. Since no screw type fixing elements are used, this method is particularly useful for furniture that has to be dismantled for transportation.

Filed: 1975-06-21
Abstract: Aq prepns. for textile treatment contain acrylamide polymers prepd. in the presence of radical formers and mercaptans contg. gps. with a basic N atom. Used to impart stiff and hydrophobic finishes to textiles upon drying. Also as filling finishes for cellulose fibres such as cotton, linen, rayon, for treating synthetic fibre textiles, mixed textiles and wool, as ingredients for schreinerising finishes; as finishes for clothing materials and interlinings, as sizes which react with HCHO condensates and can be fixed on the fibre to form wash-resistant finishes. The stiffness can be varied by incorporating other components in the polymer, e.g. acrylic esters. The polymers are compatible with the other components in the prepn. and the aq. prepns. do not yellow when acidic substances are added to vary the mol. wt. of the polymer. Generally, these copolymers contg. amino end gps. have increased affinity for the acid gps. of fibres and dyestuffs.

Title: Liquid level monitor in closed vessel - uses oscillation and feedback circuit with two capacitors
Inventor: KLEBANOFF LEONARD
IPC: G01F23/26
Filed: 1975-07-21
Abstract: A level detector for a vessel containing medical transfusion liquid has a circuit with an amplifier with a feedback terminal. The feedback circuit has two capacitors with open dielectric space, mounted one above the other. They are in different feedback paths, and their electrodes are of the same shape. Currents flowing through the capacitors are the same when both have the same dielectric, and different when they are different. A derives a resultant feedback signal from the difference between the two currents, with the current through the upper capacitor providing a negative component, and current through the lower capacitor a positive component for the resultant feedback signal. The circuit oscillates when the positive component is applied to the amplifier feedback terminal.

Title: Soluble matter concn. - using semipermeable filter bag in vacuum chamber receiving soln. through filter layer
Inventor: LEHMANN ERICH
IPC: B01D11/02
Filed: 1975-10-17
Abstract: Concentrates of soluble matter, such as albumin concentrates, are produced by dissolution and concn. on the principle of vacuum filtration by means of a semipermeable filter bag. The sample is laid on the filter layer on which a solvent is poured at the rate at which is passes through into a filter bag. The latter is arranged in a vacuum chamber so that the matter concentrates at the closed bottom of the bag. This replaces the two stages (homogenisation with solvent and ultracentrifuging; concn. by evapn. or lyophylisation) by one stage. The process is speeded up and produces reliable results.

Title: Tone-in-tone dyeing of mixed fibres - by applying a coupling component followed by a dispersion dye contg. unreacted diazo component
Inventor: SCHAUB ANDRES
IPC: D06P3/68
Filed: 1976-02-19
Abstract: Tone-in-tone dyeing of mixed fabrics of synthetic and natural fibres with the same azo dyes, comprises (a) applying a soln. or dispersin of one or more coupling components and drying, (b) printing or impregnating with a paste or soln. contg. one or more dispersion dyes made from the same coupling components as in (a), and excess diazo components, so that these form the same dyes by reaction with the coupling components, and (c) heat treatment. Esp. for polyester-cotton blends. Very level shades are obtained, without use of glycol swelling agents. Only diazo and coupling components are used, without highly-dispersed dyes, so that staining of the natural fibres by the dispersion dye is easily washed out and shows no tendency to deposit again from the wash water.
