Abstract: This invention concerns a wave-guide laser, i.e. a gas laser where the gas is contained in a tube which acts as an optical wave-guide for the laser beam. Such lasers are already known. An important disadvantage of earlier lasers of this type has been the difficulty in making the cavity tight. In addition it can, at least for long cavities, be difficult to manufacture the ceramic walls so straight that the cavity is acceptably straight from an optical point of view. This invention solves the known problems by the wave- guide being made of a thin, essentially straight ceramic tube 1 of constant diameter and wall thickness, which achieves sufficient straightness from an optical point of view, by being fixed between carefully prepared jaws 2. <IMAGE>

Abstract: The present invention relates to a distribution plate for low-velocity type supply air terminal devices which include a distribution chamber which functions to receive air flowing from a delivery channel and which includes a wall which extends parallel with the inflowing air and which is provided with a circular hole, wherein said air exits from the distribution chamber in a divergent flow pattern, and which distribution plate has means for mounting the plate in the circular holes and is provided with one or more openings. The inventive distribution plate is characterized in that one side of the plate is provided with air deflecting devices which protrude out from the plane of the plate. The air deflecting devices have an eyelid-like shape and cover and enclose from between about one third to about one half of the area of respective openings. The openings and the air deflecting devices together form a flow path which is adapted to deflect the air passing through the plate openings in an essentially loss free fashion. The openings and associated air deflecting devices are formed so that the air will exit through all openings in the plate in one and the same direction.   The invention also relates to the use of the inventive distribution plate in low-velocity type air supply terminal devices so as to achieve both horizontal and oblique flow of the exiting air. <IMAGE>

Abstract: PRESSURE OXIDATION METHODS FOR GOLD EXTRACTION AND TOXIC WASTE TREATMENT The present invention provides methods for extracting gold from refractory auriferous material, such as a gold-containing ore, a concentrate thereof, a reclaimed sulphide concentrate or some combination thereof, including the steps of mixing the refractory auriferous material with at least one toxic residue exhibiting a low sulphur content to form a low sulphur content mixture; pressure oxidizing the mixture; and cyaniding the oxidized mixture. Methods for extracting gold while simultaneously decreasing the toxicity of previously generated toxic wastes are also discussed. The gold extraction/toxic waste treatment methods preferably involve mixing refractory auriferous material with first and second toxic residues of low sulphur content; pressure oxidizing the mixture; and cyaniding the oxidized mixture. In these methods, contaminants in the toxic residues (e.g., iron and arsenic) combine with each other or with other feed components to form inert molecules having a decreased environmental impact.

Abstract: Apparatus for automatical bringing of soft, flimsy, flat articles from an undefined position to a known position. Before mechanical folding of articles such as towels and sheets the article has to be brought into a correct position from an in general undefined. An undefined position arises for instance after drying of laundry when the articles may fall unguided. The articles are from here handled manually as it has shown difficult to automate. The invention solves this problem. The apparatus consists of horizontal bars (2) with clamps (3, 4) for bringing the article along. The bars are moved by a conveyor (5) stepwise to fixed positions from a starting position to an endposition at the same time as tip (B, C and D or E) is sought, gripped and moved to the clamp in question by a front searching device (10), a middle searching device (11) and a rear searching device (12). For gripping and moving of the article in the beginning a loading device (9) is used. The clamps are activated and positioned along the bars by activators (6). In the endposition the article is hanging by two chosen corners in a known position.

Abstract: The present invention relates to a method for correction of frequency, time window error, sampling clock and phase error at OFDM-receivers. The information which is transmitted in a signal which includes several carriers in digital form, includes consecutive frames comprising a number of symbols. In respective frames at least one up-chirp and one down-chirp is arranged. Correction of the frequency is made based on analysis of the up- and down-chirps. Further the main focus of the weighted impulse response is determined. The position of the main focus is used for correction of the time window and the sampling clock. Further the vectors from the location of the received carriers are registred in relation to their ideal location in a matrix. The angles between the received vector and the ideally located vector are determined and are weighed together with regard to the amplitude of the transmission function at the frequency of the carrier and the distance of the vector to the origin of coordinates. An average is after that made of the weighed angle distances. The obtained average is used for correction of the phase error. Further, the knowledge of the obtained phase error and previous phase errors is used for estimation of the coming phase error in the following reception.

Abstract: A treatment device which uses cold red and infrared radiation for the photodynamic stimulation of cells, especially cells of human tissue. The described device produces a constant energy radiation by the use of semiconductor and/or laser diodes, which furthermore radiate light in several separate wavelengths due to a special operation mode. With help of sensors the advanced controller system is able to test the patients for the needed radiation doses in order to avoid overstimulation. Furthermore the radiation openings in the applicators are advantageously covered with a polarization filter, whereby the absorption in the irradiated tissue is increased. The basic equipment consists of a standpillar, with which machine applicators are connected with a jointed arm. The machine applicators are adapted for the treatment of large area tissues, for example, the back of humans. The standpillar is freely movable on wheels and includes a control mechanism, whereby the various parameters for therapy can be adjusted and switched ON and OFF. The standpillar is also connected to a hand applicator designed for the treatment of small tissue areas, e.g., acupuncture points. Another version of the hand applicator is especially devised for dental treatment, whereby the head piece of the hand applicator can be connected with an expander containing an optical fiber. Photodynamic substances are introduced into tissue to be treated, which enhances the effects of light irradiation by the inventive device.

Abstract: The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor is provided with outlets in the lower part thereof and is arranged in a separating tank. At least one suspension inlet extends eccentrically into said reactor. The supplied suspension is guided into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor via the suspension inlet. A circular flow is thus created which drains off from the flocculation reactor downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank. In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.
