Abstract: The percussive tool has a pneumatic impact piston with a pointed nose so that a hole is produced by compacting yielding material. A radially elastic piece of tubing is used to fix the air distributor which governs the admission of air to the front working chamber or the rear exhaust chamber of the tool. When not inflated, the piece of tubing can be moved by tensioning the air hose attached to it. Tool Can be used to produce holes for cable or pipe laying through embankments in non-rocky ground. The change from the forward working position to the backward retraction position of the tool, is simplified. Accidental displacement of the air control distributor is reliably prevented.

Abstract: A cold metal ring is greatly expanded in radial diameter and simultaneously contoured to a desired cross-sectional shape by successively rolling the ring between selected pairs of roll dies. If necessary, the ring may be annealed between successive cold rolling operations sufficiently to permit movement of ring material without fracturing the ring. Thereafter, the rolled ring may be expanded to a precise radial diameter utilizing a precision expander. Dimensional and contour control of the ring is comparable to that attainable by machining.

Abstract: There is provided a method and an apparatus for the operation of a fluidized-bed incinerator wherein a portion of the fluidized-bed medium (2) of the furnace is caused to pass a heat exchanger (8) during tapping from the combustion chamber of the furnace, and after cooling in the heat exchanger (8) is returned to the fluidized bed in the combustion chamber. The cooled fluidized-bed medium may be returned directly to the fluidized bed in the combustion chamber or it may be returned to the combustion chamber in an upper portion thereof and be allowed to fall through a distributor (13) so that it cools the zone above the fluidized bed at the same time as the medium is heated by waste gases from the combustion. The tapping of fluidized- bed medium is preferably controlled by a thermostat sensing the temperature of the fluidized bed.

Abstract: A chlorine dioxide generating process is described wherein chlorine formed with the chlorine dioxide is used to form acid reactant for the chlorine dioxide generating process by reaction with sulphur dioxide and water. The substantial evaporation of the water which would otherwise result from the exothermic nature of the reaction is prevented by controlling the temperature of the water during the reaction. In one embodiment, the temperature control is achieved by effecting the reaction in a cooled falling film absorber having integral cooling passages and to which liquid water is fed to form the falling film. In another embodiment, the reaction is effected in a packed tower with a substantial proportion of the product acid being recycled through an external heat exchanger and diluted with water.

Abstract: A process to produce by covalent binding conjugates of a substance containing a 2-amino-2-deoxyglycopyranosyl residue the NH2-function of which in its most stable conformation is equatorially oriented, and a substrate containing a primary amino group. This is done by subjecting the substance to degradation by diazotation to form a substance fragment having a free terminal aldehydo group, said fragment through its aldehydo group being reacted with the amino group of the substrate to form a Schiffs base which is then by reduction converted to a secondary amine. The substance is preferably selected from oligo and polysaccharides containing glucosamine or galactose amine units. The substrate is suitably selected from surface-aminated plastic objects, aminated gels and proteins. The conjugate described consists of a 1-deoxy-2,5-anhydrohexitol unit which constitutes terminal unit in an oligo or polysaccharide and which in 1-position is covalently bound to an amino group associated with a substrate.

Abstract: A method of manufacturing boat parts submerged when in use comprises producing a metallic skeleton structure shaped for easiest production by conventional metal-forming methods, and covering this structure in a mold with an adhering layer or coating of a thermoplastic resin or a rubber-based vulcanizable substance. The inner walls of the mold have high finish and the desired streamlined outer shape of the finished product, such as a lower unit of a propulsion system, or a propeller and the like. The coating functionally neutralizes the technologically conditioned and generally not streamlined shapes of the skeleton structure and provides a protection of the skeleton structure against electroerosive corrosion.

Date Dec. 5, 1985.A movable hydrodynamic nozzle which removes deposits of sand, soil, sludges etc. in a pipe system. The nozzle is connected to a pressurized water pipe and pulls the pressurized water pipe into the pipe system. When known movable hydrodynamic nozzles are used, the cleaning efficiency is lower due to strong turbulence and frothing and to the fact that the resistance of the nozzle to the water flow is large. In accordance with the present invention this problem is solved by shaping the channels which guide the pressurized water from the main inlet portion of the nozzle to the outer back portion of the nozzle, in such a way that the pressurized water is entering the channels in the same direction as it has when it enters the main inlet portion. Additionally, the inlet openings and outlet openings of every channel are preferably diametrically opposed in order to give the channel an optimally large curve radius.

Abstract: The invention relates to a method of operating a gas turbine unit comprising a combustion chamber, a high pressure turbine driven by gas from the combustion chamber, and a low pressure turbine driven by gas from the high pressure turbine, means for controlling the gas supply from the high pressure turbine to the low pressure turbine, and a low pressure compressor driven by the low pressure turbine, and a high pressure compressor connected in series with the low pressure compressor and driven by the high pressure turbine for supplying pressurized air to the combustion chamber, the useful power of the gas turbine unit being adjustable by controlling the gas conditions upstream of the low pressure turbine by said means. Substantially all the air delivered to the combustion chamber from the compressors, is utilized for the combustion in the combustion chamber. The generated gas is cooled with water and/or steam to a temperature which corresponds to the maximum operating temperature of the high pressure turbine. There is made use of the power obtained from the combustion chamber by said cooling, and the useful power of the gas turbine unit is recovered from the high pressure turbine at substantially constant rotational speed thereof. The temperature of the gas supplied to the high pressure turbine is maintained substantially constant independently of the useful power recovered from the gas turbine unit.
