Title: Washing textiles and dishes - using compsns. contg. calcium bonding crystalline aluminium silicates having rounded corners and edges
Inventor: SMOLKA HEINZ DIPL CHEM DR
IPC: B08B3/08
Filed: 1975-07-14
Abstract: Solid surfaces are washed and cleaned by using an aq. bath contg. finely divided dispersed water-insol. synthetic crystalline Al silicates having compsn. 0.7-1.1 Cat2/n.1 Al2O3.1.3-3.3 SiO2 (I) (where Cat is a Ca ion-exchangeable cation having valency n, esp. an alkali cation, partic. Na), as bonding agents for water-hardeners. Novelty consists of using (I) having rounded corners and edges (cpds.I'). Pref. >=80% (I') have particle size 8-0.01 (6-0.01)u, and (I') contain no particles >30mu. Use of (I'), in place of well-formed crystals of (I), accelerates ion exchange and improves washing power. (I') form a more stable suspension in treatment baths and are rinsed out more easily from machinery and articles. Use of (I') allows lowering P content of baths to 0.6 (0.3) g/l organic and/or inorganically bonded P. In an example, (I') contg. 0.99 Na2O. 1 Al2O3. 1.83 SiO2 4H2O was tested by washing cotton at 90 degrees C, without other additives. Washing power corresponded to that of Na5P3O10.

Title: Electronic monitor for car electric system - with transistorised switch for buzzer if any system left switched on
Inventor: WASSMER GERHARD
IPC: F04D29/28
Filed: 1975-07-18
Abstract: The car electrical system is fitted with a transistorised switch which operates a buzzer if any system is left switched on when the ignition is switched off. The transistor is inhibited from switching by a diode linked to the ignition circuit. If the ignition is switched off then any circuit left on provides a current through the resistor chain which in turn switches the transistor on to operate the buzzer. The system is superior to systems in which the signal operates when the car door is opened. It is easily retrofitted in any vehicle.

Title: Grinding wheel with diamond or boron nitride grinding inserts - has array of pyramidal grinding inserts with underlying sintered metal support disc
Inventor: EFFGEN GUENTER
IPC: B24D7/06
Filed: 1976-01-20

Title: Opening gill covers of fish for beheading - oblique rails guide accurately irrespective of fish size
Inventor: SCHMIDT UWE DIPL ING
IPC: A22C25/14
Filed: 1976-03-02
Abstract: For the opening of the gill covers of fish transported on their sides, belly forward, obliquely to the line of motion of the conveyor bringing them to the decapitating station, the fish, held down by a pressure lever is forced past a guide with a ramp which presses the head backwards against the neck, so that two guide rails of a centralising device engage under the opened gill covers, and lead the fish accurately to the topping knives. Method gives improved alignment of the fish and consequently reduction of the loss of flesh on decapitation.
Patent DE-2610073-A1 (DE)
Title: Regeneration of loaded activated carbon - using desorber with heated tubes through which carbon passes and recycle of gases
Inventor: NOACK ROLF DR ING
IPC: C01B31/08
Filed: 1976-03-11
Abstract: Activated carbon or coke granules are reactivated by heating them in a vessel through which they are passed. In the lower part they are cooled and drawn off as cooled granules. In the upper section the flow is split into a number of small streams. These are then heated by contact with walls heated by a hot gas stream. Some of the regeneration gas formed is recycled back to the bed and flows up through the heated zone. In the lower zone, cold inert gas is recycled to cool the carbon. An excess of approx. 5% of the vol. of regeneration gas is injected as inert gas to ensure that there is always a net flow from the cold to the hot zone. Used for reactivating carbon esp. when leaded with SO2.

Title: Image fault detection system - uses optical filter in plane of spatial frequency diffraction spectrum blocking correct spectrum
Inventor: KLOTZ ERHARD ING GRAD
IPC: G01N21/956
Filed: 1976-04-15
Abstract: A method of detecting faults in image patterns, e.g. in integrated circuit masking, uses optical filtering. It is designed to isolate statistical errors and to simplify fault detection by reducing production complexity. The spatial frequency diffraction spectrum of the image is stopped with a flat laminar amplitude filter (4) in preferred directions defined by the preferred directions of the desired image structure. Faults in the image cause light to be transmitted. Signals due to residual light which cannot normally be filtered are separated from the error signals using a threshold detector. Light detection is by television or photoelectrical methods.

Title: Coin mfr. from composite metal strip - prevents counterfeiting by showing colour differences of metals at coin edge
Inventor: HOERNSCHEMEYER WOLFGANG
IPC: B44C3/00
Filed: 1976-11-04
Abstract: Coins which are difficult to counterfeit are made from a composite strip of metal. A strip of copper-nickel alloy containing 2.5% nickel is laid between two strips of copper nickel alloy containing 25% nickel. The strips are then heated to 1050 deg.C and rolled together to the required overall thickness. After cooling the strip, it passes under a press which stamps out coin blanks. The coin blanks are then reduced in dia. by about 0.1 mm by turning or gainding. This machining operation ensures that the edge of the inner layer of metal which is of a different colour to the outer layer, is visible even after long use making it easier to identify counterfeit coins.
Patent DE-2659471-A1 (DE)
Title: Forge for cold or hot forming small parts - uses rough rolled material passed through dies and rollers in series
Inventor: KOCH FRIEDRICH-KARL
IPC: B21J5/00
Filed: 1976-12-30
Abstract: For the manufacture of small parts to close tolerances in presses, use is normally made of rod material rolled to close tolerances or drawn and scaled material. This raw material is expensive. To avoid the necessity of using expensive raw material, rough rolled material (3) of e.g. square section is first passed between several sets of rollers (9, 10) and a pair of dies (11) in the forging machine to bring it to the required section for the raw material to close tolerances. When heated material is used, it is first warmed to such a temp. that it will have the right temp. for forging at the end of the preforming process.

Title: Anti-theft device for skis - uses irregularly shaped insert which is removed when skis are not in use
Inventor: MANSMANN IVO DIPL CHEM
IPC: A63C11/00
Filed: 1977-01-29
Abstract: In order to prevent skis being stolen, a recess (2) of a special irregular shape is cut in the running surface of the ski. This recess is then filled with a detachable piece (2) of plastic or metal which matches the contour of the recess and fits flush with the running surface. A band of colour (5) is then painted across the insert (2) and the surrounding part of the ski. The insert (2) is retained by an integral stud which passes through the ski and is fitted with a knurled nut on the other side. The insert is removed when the ski is not in use so that the recess spoils the running qualities of the ski. The irregular pattern makes it difficult for a thief to replace the insert.
