Abstract: This invention concerns a continuous manufacturing process of sections (11) or plates from soft matter (2) which is extruded under heat and encased by at least one strip sheet (3, 3'), said encased matter subsequently being calendered, shaped to the desired profile and finally cut into lengths, process which is particularly remarkable in that the matter used is a mixture containing a non-synthetic binder and water, so that the mixture becomes sticky by undergoing said heat treatment in an aqueous medium, which assures adhesion of the casing onto the matter during calendering, while the product undergoes at least one drying operation after said calendering operation. The binder is advantageously starch-based and the mixture may also contain a plasticizer, for example containing urea. The invention also concerns an installation for implementation of the process and the products thus obtained.

Abstract: The invention relates to a process for recovery of metals such as Cu, Ni, and Co from slag formed during the smelting process. Upon smelting, a slag layer is skimmed from a matte layer, containing valuable metals. Metal from the matte layer becomes entrained in slag skimmed from matte. To recover metal from matte-enriched slag, slag skulls are formed which comprise layers of solidified matte-enriched slag. Slag skulls are cooled and broken into pieces selected for high metal concentration, which. may then be either fed directly to a smelter, be further concentrated by grinding and flotation or may be upgraded using conventional gravity separation techniques such as a shaking table. Valuable metals so recovered may be added back into a smelting process.

Title: Light sensing device
Inventor: WULF JURGEN
IPC: G01N21/64
Filed: 1997-12-04
Granted: 2002-11-19
Abstract: The present invention relates to a light scanning device for exciting and detecting an emission of secondary light, especially fluorescent light, of a sample, comprising a light generating device for generating scanning light in the form of a singl e light beam, a deflection unit used for effecting a deflection of the scanning ligh t for scanning at least one subarea of the sample, said deflection being variable in at least one direction, an imaging unit for forming an image of the secondary light emanating from the sample, and a detection unit for detecting the secondary light. Whe n a sample with a large surface to be rastered is subjected to fluorescence examination with high spatial resolution, undesirably long scanning times occur. For reducing the scanning time and for simultaneously maintaining the high resolution in the case of such a sample, the light scanning device according to the present invention comprises a division device for dividing the single light beam into at least  two light beams. This has the effect that, instead of the former sequential scanning o f the sample, a subdivision into fields is carried out, said fields being scanned simultaneously by the plurality of light beams. The scanning time can therefore be reduced in accordance with the number of the simultaneously scanned fields o f the sample.

Abstract: Liquid in which oxygen-containing gas is to be dissolved is pumped through a main and distributed into faster-moving subsidiary streams. Each subsidiary stream passes through a turbulence-inducing means and air or oxygen is introduced into the turbulent region of alternate streams. The relative proportions of air to oxygen introduction are varied so as economically and efficiently to oxygenate the liquid. The gas-containing liquid passes through nozzles back into the volume of the liquid at sufficient velocity to cause further turbulence, making gas bubbles shear into smaller bubbles and also agitating the body of liquid.

Title: A dose setting device for medical injectors
Inventor: JANSEN PAUL EDWARD
IPC: A61M5/315
Filed: 1999-06-11
Granted: 2007-04-17
Abstract: Many self-use medical injectors have a knob at the rear end of a barrel which is rotated from a zeroed position to set the dose and which rotates back again, to the zeroed position, when the injector is fired. A scale is provided on the knob (2) or barrel (1) and a datum mark or indicator on the barrel or knob co-operates with the scale. Often there is a raised stud (3, 11, 12, 16) providing the indicator or the zero mark of the scale. An annular member (4, 10, 14, 17) fitted over the knob if the stud is on the barrel or over the barrel if the stud is on the knob has a projection (9, 12, 15, 18) which is registered with a mark on the scale corresponding to the required dose. This projection abuts the stud when the knob is rotated and thus sets the knob for the correct dose.

Abstract: The invention relates to a method for processing tires, producing products comprised of the tire material and a device for cutting tires and flatly constructed products or bodies e.g. blocks, mats or cords which are produced from cut tires. The invention can be applied especially to reshaping passenger car, truck or aircraft tires that are no longer acceptable for use in transportation into a new foundation as a base material which can be utilized for manufacturing products in multiple areas of the economy. Intermediate products for manufacturing new final products are made out of cut tire rings. The method is characterized in that the tires are separated into a series of segments in such a way that the two side pieces of the wheel tread are separated off and the resulting rings are joined to form new products with one another.

Abstract: A method and apparatus for identifying a material type in an article (20; 21), such as wholly or partly tranparent bottle of plastic or glass, including, with the aid of a detector station (1-16, 18, 19, 25), irradiating the article with rays from an infrared radiation source (1), detecting rays which have passed through the article non-absorbed, and then carrying out a correlation analysis of such detected rays. The article is made to pass through the detector station (1-16, 18, 19, 25) in a continuous or discontinuous movement.  The rays from the radiation source (1) are successively filtered by the filters (10) consisting of wholly or partly transparent materials which have different spectral characteristics. The rays filtered by the filters and non-absorbed by the article are intercepted in order to form a sequence of measured values representing characteristic transmission signatures of the article. A correlation analysis of the signatures is carried out in relation to statistical models in order to determine the material type of the article.

Abstract: A stabilizing and enclosure system for a series of side-by-side mobile storage units. Each mobile storage unit includes a storage member, such as a cabinet assembly, mounted for extendible and retractable movement relative to a base which is rigidly fixed to a supporting structure such as a floor. A stationary stabilizing member is provided for each storage unit. An extendible and retractable engagement mechanism is interposed between each stabilizing member and the storage member of each storage unit, and is movable along with the storage member upon movement between its extended and retracted positions for maintaining engagement of the storage unit with the stabilizing member, to prevent the storage unit from tipping. In one embodiment, each stabilizing member is in the form of a top panel which overlies one of the storage units. Adjacent top panels are connected together, and each top panel is preferably engaged with the storage unit base by a vertical post. An end panel is engaged with each endmost top panel at its upper end, and is secured to the endmost base at its lower end. An extendible and retractable engagement mechanism is interposed between each top panel and a top wall defined by one of the storage members. The interconnected top panels, end panels, rear posts and bases function to form a housing or enclosure around the side-by-side storage units, which is rigidly interconnected with the floor through mounting of the bases to the floor. Each extendible and retractable mechanism stabilizes its respective storage member during movement between the extended and retracted positions.
