Title: Determining gold content of mined rock - by irradiation with neutrons and measurement of intensity of resultant gamma rays produced by gold reaction
Inventor: CLAYTON COLIN GEOFFREY
IPC: G01N23/222
Filed: 1980-12-15
Abstract: The gold content of gold-bearing material is determined by irradiating the material with neutrons. The reaction Au-179 (nn') Au-179 m takes place, producing gamma rays of energy 279 keV. The intensity of the gamma rays is measured and gives an indication of gold content. The method is used for selecting samples of gold-bearing ore for further treatment and extraction. The method can cope with a high throughput of material, and is accurate since a property of the gold itself is used as an indication.

Title: Aeration device and a process for circulating and aerating water, in particular lakes
Inventor: BEHAM HANS
IPC: B01F7/16
Filed: 1982-02-12
Abstract: An aeration device for circulating and aerating water, in particular lakes, includes a rising pipe via which water is pumped from the bottom water layers to the top. In order greatly to reduce the production and operating costs compared to known apparatuses, a rotating body (7) is provided at the top end (5), the water pumped up being essentially horizontally sprayed out through water outlet points (33) at the top end of the rising pipe (33) and thus being enriched with oxygen. In order to permit hypolimnic aeration, the oxygen-enriched water is returned to the bottom water layers via a collecting tank (9) and a downstream water descending pipe (13). A method of operating the aeration apparatus (1), which is particularly favourable in terms of costs, is made possible by a drive (31) in the form of a wind-drivable rotor, starting from which, the rising pipe (3) serves as a drive shaft for the rotating body (7) and/or the pump (15). <IMAGE>

Patent DE-3206544-A1 (DE)
Inventor: SCHARMER WOLFGANG DIPL ING
IPC: B65G27/32
Filed: 1982-02-24
Abstract: Manufactured goods such as cast components to which molding sand is still adhering, are treated in a vibratory conveyor chute for cleaning and cooling the goods. As the goods travel down the chute they are exposed to force components extending perpendicularly and across to the travel direction along the length of the chute. These force components impose on the goods a revolving motion along a helical path. This revolving motion may be improved or intensified by directing the resulting force components (R, R') of the force causing the revolving motion to extend at a spacing from a so-called "center of gravity line" (S, S') defining or interconnecting the center of gravity points along the length of the vibratory chute system. This spacing causes a distribution of the goods (11) in the chute such that the goods (11) have a slanted surface (10) in the chute (1). Thus, the vertical acceleration values (kv) are larger at the upper return zone 26 than they are at the lower return zone 27. This type of treatment combined with the conveying movement is applicable to various kinds of goods and treatment procedures.

Patent DE-3212328-A1 (DE)
Title: Heat treatment with dynamic temperature control
Inventor: SCHIRMER WERNER PROF DIPL ING
IPC: C21D1/34
Filed: 1982-04-02
Abstract: The invention relates to temperature control during the heat treatment of workpieces by the indirect heating principle. The object of the invention is to shorten the total duration of the heat treatment, to increase the certainty of obtaining the desired properties, and to save energy; the technical object is to shorten the heating and soaking durations, as against conventional processes, by over-raising the surrounding and marginal temperature for limited periods. According to the invention, the workpiece is heated a minimum of 50 K over the required reference temperature and a maximum such that no technically unjustifiable workpiece damage can occur. After the throttling of the external energy supply, the flow of heat from the workpiece skin to the workpiece core is regulated such that the core is heated to the reference temperature. The cooling rate of the temperature of the surroundings is then smaller than the rate of temperature equalisation between skin and core. After this, the usual heat treatment stages are immediately concluded. The invention can be used in all fields of technology in which temperature regulation is accomplished indirectly during the heat treatment of workpieces.
