Title: Automatic banknote testing - uses thermo-chromatic dyestuff strips and controlled temps. to check colour change
Inventor: SCHREYER ALFRED ING
IPC: G07D7/12
Filed: 1979-03-13
Abstract: The structure of a banknote paper, for use in automatic sorting and dispensing machines, incorporates a thermochromatic pigment dyestuff on its surface or distributed within the paper structure, which changes colour temporarily at a given temp. or higher. An electrically conductive substance is added to the dyestuff to be heated by electro-magnetic oscillation of >=10kHz. Specific materials are graphite powder, metallic powder partic. of Al or Cu or a powdered noble metal, or pref. ferro-magnetic matter such as Fe and/or Ni powder. The pigment dyestuff is applied in strips across the paper either on its surface or within the paper structure. The system allows the validity of the note to be checked, without damaging the currency note, and prevents forgery.

Title: Hairdressing aid for layer-cutting hair - uses bandages wrapped round between layer partings to give correct line
Inventor: IHNE HANS EUGEN
IPC: A45D44/02
Filed: 1979-07-09
Abstract: When cutting the hair a horizontal parting (2) is made above which all the hair is drawn up. A bandage (3) is then unwound from a support rod (5) placed at head height and wound round the head so that its upper edge joins with the partings. A further parting (7) is made at distance above the first parting (2) whereupon the hair (8) between the two partings is drawn down over the bandage (3) and then cut parallel to the edges (6,9) of the bandage. This process is repeated up the hair line for as many layers as required. The stand supporting the bandages can also take other hairdressing equipment.

Title: Monitoring and control of fuel gasification - on basis of coolant water flow rate and temp.
Inventor: PEISE HELMUT
IPC: C10J3/74
Filed: 1979-09-05
Abstract: A process is claimed for monitoring and controlling the partial oxidn. of an ash-contg. fuel in a gasifier of the type in which the reaction chamber is surrounded by cooling surfaces in the form of one or more parallel tubes through which liq. H2O (pref. pressurised) is circulated. The process comprises (a) measuring he amt. (W) of H2O supplied to >=1 tube section per unit time, (b) measuring the H2O temp. (T) at several (>=2) points along the tube, and (c) multiplying W by the difference in T (DELTA T) between 2 points along the tube. The product W DELTA T is used as a measure of the ave. temp. in the section of the reaction chamber between the temp. measurement points and/or for controlling the process (esp. by adjusting the O2 and fuel supply rates) and/or for actuating an emergency shutdown system. The process provides rapid response to variations in reaction temp. and produces a signal (W DELTA T) which is highly sensitive to variations in process conditions (esp. molten slag temp.).

Title: Surface hardening of cast iron workpiece contg. hole - esp. IC engine camshafts in which holes are chamfered so they do not become blocked during surface melting used for hardening
Inventor: EMDE FRIEDHELM
IPC: C21D9/30
Filed: 1979-09-29
Abstract: The workpiece is first provided with a hole (4) with a bore dia (d); and hole (4) is provided with a chamfer (6) extending to the surface of the workpiece. The max. dia. (D) of the chamfer is min. 1.5 (d). Hardening of the workpiece surface near the hole (4,6) is produced by brief local heating, which causes melting of the surface and a hard, ledeburite structure when the molten zone solidifies. The process is used esp. to mfr. camshafts for motor vehicles, where the camshaft is provided with at least one chamfered oil hole (4,6). The chamfer prevents the hole from being blocked by the molten surface zone formed during hardening, i.e. the burner flame employed for surface hardening can now be fed across the hole.

Title: Consolidating synthetic rubber particles - where container is sealed and air driven from material before central ram compresses mass
IPC: B30B11/02
Filed: 1980-01-24
Abstract: Powders, and synthetic rubber in particular, are compressed into blocks using a container between a top sliding plate and a pressure cylinder. A hopper feeds the container which is closed off by the sliding plate and receives a vertically moving ram. Hydraulic cylinders are fitted to the outside of the container, they lift it to close a gap between the sliding plate and the top of the container, the main vertical ram is first energised at low pressure and then at high pressure when the above gap is closed. Pressure container is fully sealed and air is effectively excluded from the pre-pressed mass.

Title: Activated water for degradation of viruses and microorganisms - produced by subjecting to cosmic radiation or neutron bombardment in pyramidal containers
Inventor: HANSCHMANN HORST
IPC: C02F1/00
Filed: 1980-06-26
Abstract: New proposal for the degradation of viruses and microorganisms entails activating water, lithium waters (e.g. from Bad Duerkheim) or water contg. 6Li, with or without ozonised water, in pyramidal containers 30cm in height having the proportions of the dwarf pyramids in the Louvre or of Cheops' pyramid, with more or less thick walls, by decomposition using cosmic radiation (e.g. in the upper atmosphere in an aeroplane or a weather balloon, or with harder components of cosmic radiation at ground level) or with neutron radiation in a nuclear power plant, to give a product approximately corresponding in concn. to Ganges water, or having a higher concn. The activated water breaks down bacteria and viruses, or reduces them by a half, within 5-10 mins., even though it does not emit measurable beta-radiation. It can be used for rinsing diseased internal organs, or eyes, ears and other body cavities. A pyramidal container filled with the activated water may be used as a reservoir for a domestic humidifier so as to maintain a relative humidity of 90% with the activated water.
