Abstract: The method enables the treatment of masses of waste including thermosetting plastics materials, high-melting thermoplastics materials, aluminium, wood, paper, fabrics, etc. The mass of waste is first subjected to a grinding process, preferably in two stages (4, 5), to reduce it to a maximum particle size of the order of 10 mm. The granular material thus produced undergoes a heating and mixing process (8) and is then reduced to sheet or strip form (15) and simultaneously cooled (11a) in order to undergo a scraping or shaving process (13) which leads to the formation of a mass substantially comparable to a powder with a particle size of between 50 and 1000 microns, including a certain quantity of fibres. The shavings produced can be mixed with a better-quality plastics material, at least some of which may be produced from fairly large articles made of plastics materials which are first separated from the mass to be treated and ground separately (4a, 5a), to produce a recycled plastics material in which the fraction of thermosetting materials, high-melting thermoplastics, aluminium, etc. constitute a filler and a fibrous reinforcing structure.

Abstract: The present invention provides a method and apparatus for rendering a three-dimensional object by a plurality of dots, in which calculation is simple, dots are uniformly arranged on the surfaces of the object, and the direction of the body can readily be ascertained even after the object has been rotated on the two- dimensional display screen. The surfaces of the object are divided into a plurality of domains and the dots are arranged on these domains according to different rules. To render a body of rotation by dots, the surfaces forming the body are divided into first and second domains. The first domain includes those surfaces for which the rate of change of the radius of gyration measured from a notional axis of rotation is larger than the rate of change of the radius of gyration of surfaces in the second domain (e.g. polar domains and equatorial domain for a sphere), and dots are arranged in each domain according to different rules.

Abstract: s7 In order to enable a gripper carried by a rapid moving gripper conveyor to be opened and therewith release an object gripped by the gripper, for instance a newspaper, without influencing neighbouring grippers, the gripper is opened (45', 47) while moving along a path which is shorter than the distance (t) at which the grippers are spaced on the gripper chain (1) and the opened gripper is held open by means (4, 45') which only act on the thus opened gripper. The means which holds the gripper open accompanies the movement of the gripper conveyor. The method and the arrangement find use in conveyors that are provided with self-closing grippers where the conveyors have a high conveying capacity and enable independent release of individual objects. An opened gripper is held open while the gripper moves through a distance which is greater than the gripper spacing interval and which is sufficiently long to ensure that the object will fall free from the gripper.

Abstract: Laser imaging apparatus, such as a storage phosphor reader (10), which minimizes image artifacts in a detected electronic image signal caused by nonuniform light collection efficiency across the length of the scanned image light collector. A laser (12), such as a gas laser, produces a laser beam (14) having a stimulating (scanning) light at a first wavelength and additional spontaneous emission light at a second wavelength. The stimulating light is scanned in a line scan direction across a storage phosphor (18) having a latent image to stimulate the storage phosphor (18) to emit a light image. A light collector (20) collects the light image and a photodetector (22) detects the collected light and produces an image signal. In a calibration step before main scanning, the additional light is scanned in a line scan direction across a diffuse reflector. The light collector (20) collects the reflected light and the photodetector (22) produces an image correcting signal. The image signal and image correcting signal produce a corrected image signal representative of the latent image.

Abstract: In a redundant array of disks, the disks are divided into areas of different sizes, so that small amounts of data can be stored in an area of an appropriate size on a single disk, instead of being spread over multiple disks. A usage status table indicates which areas are in use. Check information is generated and stored only for areas indicated to be in use. When new check information is generated, it is therefore possible to omit the reading of unnecessary old data and old check information. When a disk fails and is replaced with a standby disk, only the data in areas indicated to be in use are reconstructed. Check information can be stored on a solid-state disk.

Abstract: Methods for inspecting bottle crates are already known, in which the compartments holding the bottles have a symmetrical grid pattern 12, the bottle crates being transported past an inspection station. The bottle crates (2) are inspected for damage and foreign bodies. It is a disadvantage here that all the designs of the grid pattern of the delivered bottle crates must be known at the time of installation of the inspection station and must be stored in the system as a "good pattern". In order to solve this problem, the method detects the respective grid pattern (12) of the bottle crate (2) transported at that time past the inspection station and stores it in an evaluation circuit (7). Thereafter, the symmetry of the respective grid pattern (12) is checked in the evaluation circuit (7) and the corresponding bottle crate removed if the deviation from symmetry is more than a known amount. <IMAGE>

Abstract: Sensitive deep ultraviolet resists are formed utilizing a material that undergoes decomposition to form an acid together with a polymer including a chain scission inducing monomer such as sulfonyl units and substituent that undergoes reaction to form an acidic moiety when subjected to the photogenerated species. An exemplary composition includes poly(t-butoxycarbonyloxystyrene-sulfone) and 2,6-dinitrobenzyl-p-toluene sulfonate. The sulfonate decomposes to form sulfonic acid upon irradiation. This acid reacts with the polymer group to form an acid functionality while the sulfone moiety of the polymer induces scission. As a result, the irradiated portions of the resist material are soluble in ionic solvents while the unirradiated portions are not.

Abstract: A process for the direct production of sponge iron particles and liquid pig iron from iron ore pellets is described, in which the iron ore is reduced as a loose fill (bed) in a direct-reduction unit by means of hot reduction gases to give sponge iron and is then smelted, in a smelting gasifier, by means of introduced carbon and injected oxygen-containing gas, reduction gas being generated at the same time. At least a portion of the reduction gas, having been cooled to the temperature required for the reduction, is passed into the reduction zone of the direct-reduction unit. A considerable fraction of the carbon and of the reduction gas is due to the initial presence of a mixture of hydrocarbon-containing plastic and petroleum coke and/or coke (breeze). The reduction gases are primarily produced, at least in part, by cracking (from the plastic) and by thermal gasification (from the coke).
