Title: Process and apparatus for refining a metal bath containing solid cooling materials
Inventor: METZ PAUL
IPC: C21C5/46
Filed: 1982-07-22
Granted: 1986-10-16
Abstract: 1. Process for refining a metal bath containing substantial quantities of solid cooling matter, in particular scrap metal, which provides for a refining operation through blowing of oxygen from the top on to the surface of the bath and introducing powdered carbon suspended in a neutral gas jet into the bath, said jet being directed on to the bath surface, characterized in that a velocity of the order of Mach 1.5 to Mach 2.5 is imparted to the jet and in that a quantity of neutral gas is injected simultaneously into the bath, through permeable elements lodged in the bottom of the vessel, which is sufficient to prevent foaming of the slag under the effect of the added carbon.

Title: Aerosol cleaning agent
Inventor: TROGER WOLFGANG
IPC: C11D3/12
Filed: 1983-01-22
Granted: 1986-08-07
Abstract: An aerosol cleaning agent for textile surfaces, particularly for the cleaning of textile upholstery, contains a plasticized urea-formaldehyde resin foam, a propellant, an antisettling and suspending agent respectively and a liquid. In order to obtain improved cleaning action and improved removability from the article to be cleaned, the aerosol cleaning agent comprises approximately 65 to 75 wt % active substance. This active substance contains sodium-aluminum silicate suspended therein and buffered by acid to a pH of about 7-8-and the plasticized urea-formaldehyde resin foam has open-cell foam particles and is present in particle sizes between the limit values of about 0.005 and 0.120 mm and a density (in dry, non-comminuted condition) of about 50 plus or minus 10 kg/m3. Therefore it is possible to dispense with the addition of a moisture-retaining cation-active antistatic.

Title: Improvements in or relating to the casting of metallic materials
Inventor: STEWARD NEIL DAVID
IPC: B22D27/02
Filed: 1984-02-16
Granted: 1987-07-09
Abstract: A process for casting molten metallic material having a solidification range of temperatures, especially alloys containing more than 80% aluminium, involves simultaneously stirring and cooling the molten material to a temperature between 0 DEG  C. and 75 DEG  C. above the liquidus temperature of the metallic material using hollow heat transfer rods (9) extending across a duct (4), down which the material is caused to flow. The material is then caused to solidify with a substantially non-dendritic microstructure by rapidly cooling it in a continuous casting machine. The solidified bar so produced may then be reheated at a steady rate to a point between its liquidus and solidus temperature until it contains between 30% and 70% by volume solids content but can still be maneuvered without losing its shape. It may then, with a minimum of delay, be rapidly formed into a solid article of any desired shape by, for example, casting in a pressure casting machine.

Granted: 1987-12-03
Abstract: The heat exchanger in particular the cooler has an outer casing (1) and an inner quadrangular chamber (1 min ) which contains a plurality of tubular conduits (from 7 to 21) inclined to one another and in respect of the direction of movement of the viscous fluid, alternatively crossing and having a circular section with a superimposed plate to force the fluid streams of the viscous liquid which passes through them in vertical direction (arrows 22 and 23) to diverge when they leave each tubular conduit and to mix with the adjacent diverging flows in consequence of the crossing of the said tubular conduits. The cooling water enters an adjacent chamber (3), passes through the aforementioned tubular conduits and leaves from the opposite side in an adjacent second chamber (4) to recirculate in closed cycle with high velocity and quantity. Only the heat given up by the viscous fluid is restored. Each unit is modular, that is, superimposable to increase the cooling capacity.

Abstract: In a light barrier, especially for outside application and long distances monitored, insensitivity to interfering light and scattering through fumes or fog and an increased range and sensitivity to objects passing through the light barrier are achieved by subdividing radiation from a source into two radiation branches which are offset relative to each other and differently polarized, e.g., by means of a polarization filter divided into two parts, with different linear or oppositely circular polarization of the filter part surfaces. By means of an analogously subdivided polarization filter, the radiation of each of the two radiation branches is focused on a different individual sensor element. The two sensor elements are connected in a differential circuit which triggers an alarm signal in response to signals arriving from both radiation branches in short succession but does not trigger an alarm signal if both sensor elements are equally irradiated.
