Title: Consolidation of mineral mixts - as used in roa-building by mixing with water-in-ol emulsions
IPC: C08L95/00
Filed: 1971-04-24
Abstract: Size-graded stone mixts. are intimately mixed with a water-in-oil emulsion and subsequently consolidated, esp. in prodn. of flexible bearing layers in road construction. Pref. the fine sand component, (below 2 mm) is mixed with the emulsion to a pasty mass and this mixed with the other mineral components. The emulsion oil phase pref. consists of (A) a thin oil, pref. tar oil and for hydrocarbon fractions of b.pt. 200 degrees-400 degrees C, (B) tar, fatty acid pitch, tall oil resin and/or root resin, (C) a water-oil emulsifier. Ratio of fine sand to oil phase is pref. 3-10:1. The emulsion serves to increase the water content and reduce evaporation so that separation of coarse and fine components during transport and storage is retarded. It also acts as a lubricant in assisting consolidation without loss of flexibility as occurs with hydraulic binder or bitumen addition.

Title: Rotating spherical piston engine for motor vehicles - has spherical pistons which are connected directly with levers to the power takeoff shaft
Inventor: FAEHRMANN KURT
IPC: F02B53/00
Filed: 1973-08-25
Abstract: The piston system connected to the power take off shaft is split in half and it forms a toroidal cylinder with a spherical piston. The combustion air is compressed by the spherical piston. The explosion in the combustion chamber drives the spherical piston through the toroidal cylinder. At the end of this cylinder the spherical piston impinges on the semicircular hydraulic cylinder of the opposite half of the split piston assembly. This causes rotating movement. Due to the asymmetrical operation of both hydraulic cylinders the exhaust gases are pushed out. This arrangement uses less fuel than other engines.

Title: Identification of objects carrying stickers on one surface - involves scanning with video camera and processing its signals
Inventor: ZIMMER GEORG
IPC: G06K7/10
Filed: 1973-10-08
Abstract: The invention relates to processes and equipment for improving the identification of objects, such as warehouse goods etc. which carry labels holding data on one surface.

Title: Smoke prodn for smoking foodstuffs - using cyclonic chamber inside electric furnace into which sawdist and gas are injected
Inventor: FESSMANN GERHARD
IPC: A23B4/052
Filed: 1974-03-11
Abstract: A smoking medium for curing food prods. is produced in a cyclonic chamber located inside a furnace with electric resistance heating. A hot gaseous medium (hot steam and/or hot air), is injected tangentially to form a spiralling path in the chamber. Into this is injected a stream of sawdust. Smoke is produced by the thermal degradation and/or partial combustion of the wood particles. The particles tend to flow down the walls and spent particles collect as ash in acontainer. The smoke thus produced then leaves. If superheated steam is used, the temp. should be 250-400 degrees C while for hot air the temp. is 250-500 degrees C.

Title: Thermo-nuclear reaction chamber - inducing pinch effect compression by displacement of chamber side walls
Inventor: OHKAWA TIHIRO
IPC: H05H1/02
Filed: 1974-07-01
Abstract: Reaction chamber contains a conducting fluid e.g. lithium, quicksilver, copper or sodium is within the long central cylindrical bore formed by the walls of the chamber. An externally applied magnetic field induces a rotation of the fluid at a velocity sufficient to create an evacuated void coi-incider with the central axis of the chamber by centrifugal force. A plasma introduced into the void by laser or other means is magnetically restrained and its density increased by a 'pinch-effect' created by an inward movement of the side walls reducing the void vol. and increasing the plasma temp. to thermo-nuclear level. The chamber is used in plasma physics and dimensionally smaller plant can be employed with a reduced magnetic field requirements.

Title: Medical instrument sterilisation device - with sheath contg ethylene oxide released by hand-operated valve or bursting ampoule
Inventor: ELLIOTT JOHN DR
IPC: A61L2/20
Filed: 1974-07-17
Abstract: Medical instruments (hypodermic needles) are sterilised by introducing them into an inner bulb which is connected by a valve to an outer flexible sheath filled with a sterilising gas such as ethylene oxide. Finger pressure on the valve opens it and allos the gas to enter the inner bulb with the instrument. The inner bulb and valve can be replaced by a fragile ampoule with the gas which can be burst by hand pressure. This is a simple and handy device for sterilisation which can be employed immediately prior to the use of the instrument.
