Title: Purifying industrial effluent - by biological oxidn in aeration/oxygenation tank
Inventor: PARSCH HANNS
IPC: C02F3/20
Filed: 1972-02-02
Abstract: Industrial and other waste effluents are purified by accelerated biological oxidn. in a rectangular tank in which the effluent is circulated around a horizontal, perforated partition, while a stream of oxygen and/or air bubbles are released near the base of the tank. The bubbles pass through liq. currents flowing in opposite directions on opposite sides of the partition, each rising bubble being double-deflected to take an extended contacting path to the surface; the oxidising gas is thus used very efficiently and the treatment capacity to size ratio of the plant is high.

Title: Fusion-breeder reactor - using hydrogen fusion and yielding tritium nuclear fuel
Inventor: GENSWEIN ALFONS
IPC: G21B1/00
Filed: 1972-06-21
Abstract: A hydrogen-isotope mixt. (D-T Gas) is fed in metered discrete quantities into a very high energy accelerator of the plasma compression type, or conical induction type using external field, and thence passes via a "magnetic nozzle" into a transit-time delay and pulse-shaping stage in which either during or after its transit it is brought to fusion by very high flux density constriction field(s). Then it is allowed to expand in a chamber, lined like the reaction chamber with a liquid lithium filled jacket where neutron breeding of tritium takes place, and in the expansion chamber the plasma temp falls to a level at which it can be used industrially i.e by passage through heat exchangers using as secondary, working fluid, one adapted to use at that temp. this fluid then being used for desired form of energy prodn externally. The heat energy given up to the working fluid is that produced by fusion and stored in the gas and/or in the lithium circuit.

Title: Location and display of distributed radiation sources - compares calibration data from known sources with data from unknown sources
Inventor: BLUM ALVIN S
IPC: G01T1/29
Filed: 1973-06-04
Abstract: Calibration data are obtained from a large number of first test values from each of several radiation measuring devices, which detect each radiation from each known radiation source. Second test values are collected from each radiation and each source in a distributed radiation material whose position is unknown. The second test values are compared with calibration data, and when equal, the position of each radiation source is fixed. The read-out position data are stored and so combined, that a visual display is produced giving the position and intensity of the unknown source. The device has a collimator, scintillators, photodetectors, and a direction-controlling gear-arrangement.

Title: Tooth-picks comprising nylon monofilament bundles - held together by nylon adhesive contg. polishing powder, fluoride and flavouring
Inventor: DRAGAN WILLIAM BASIL
IPC: A61C15/04
Filed: 1973-08-08
Abstract: A number of nylon monofilaments are bent double to form a bundle which is passed through a bath contng. an alcohol soln. of a nylon, squeezed free of surplus binder and dried in a hot air stream. The bath pref. contains in suspension tooth-polishing compounds, e. g. zirconium silicate, zinc oxide, pumice powder, plus therapeutic materials such as stannous fluoride and flavourings such as citrus oils. These additives remain embedded on the surface of the nylon layer which binds the bundle of monofilaments. The spring dried bundles form tooth-picks, which, besides being able to rub away tooth film or flick out small food particles from cavities, can carry fluorides or other therapeutic substances right into cavities. The nylon binding coat, unlike waxes which have previously been similarly used, does not break away from the bundle and remain in cavities as a focus for bacterial growth.
Patent DE-2346418-A1 (DE)
Title: Automatic drum expansion brake adjuster - has nut and screw adjuster to prevent lock-up after successive heavy braking
Inventor: HAGIU FAUST
IPC: F16D65/60
Filed: 1973-09-14
Abstract: An adjustment wheel situated on the operating lever is turned by a worm and has a screw thread. The nut has a conical outer surface which mates with the inner conical surface of a bush having an external screw thread with a second lead angle and pitch radius. Heavy braking causes the bush to be rotated slightly, first in a direction outward which releases the nut to rotate under the outward action of a circumferential spring, then inward, when the bush causes the nut to rotate with it. This oscillation will cause small incremental adjustments to the brake cam. By suitable choice of the lead angles these increments can be made small enough so that when the brake drum heats and expands the total adjustment can never cause the brake to lock up when the drum cools.

Title: Domestic electric oven with dish rack - has damper controlled air passages for use as room space heater
IPC: F24C15/18
Filed: 1973-12-24
Abstract: An electric cooking oven has heating elements on the outside of the oven compartment in air spaces formed between the oven and the appliance walls. These passages are provided with air inlets and outlets which are controlled by dampers. An electrically driven fan circulates room air through these passages. When the fan is off and the dampers are closed the elements heat the oven for cooking purposes. When the fan is switched on and the dampers are opened the elements form a convective heater for the room and also discharge warm air over a dish drying rack above the oven. The passages can also be arranged for natural convection without the use of a fan.
