Patent FI-80171-C (FI)
Inventor: HARTWIG CARL SVERKER MAGNUSSON
IPC: H02P6/00
Filed: 1982-12-17
Granted: 1990-04-10
Abstract: A compressor drive system for controlling the gas pressure in a pressure gas volume (106) connected to the compressor (101). A brushless alternating current motor (23) is directly coupled to the compressor, which is driven with the same speed as the motor. The pressure in the gas volume (106) is sensed by pressure sensing means (109) connected to a converter (114). The converter simultaneously changes the amplitude and frequency of the drive voltage supplied to the motor (23). This is done in response to pressure changes in volume (106). The motor is stopped if the pressure exceeds a preset maximum value. A pressure gas container (104) is depressurized at motor stop to allow restarting without counter pressure on the compressor. Means (44) for controlling the amplitude and frequency of the drive voltage is provided so that the normal speed maximum load current is never exceeded during motor start.

Abstract: The invention relates to a process and a preservative for the preservation of animal feed. According to the process, acid-containing substance is added to fresh, newly harvested fodder in an amount sufficient to increase the acidity of the fodder immediately to below 4.5 at the most, preferably to below 4 in accordance with the principle of the AIV System. Spent liquor from acid pulping, optionally concentrated to desired concentration, is used as acid-containing substance. According to the invention, the liquor used consists of the spent liquor from a pulping process, wherein formic acid and/or a mixture of formic acid and hydrogen peroxide has been used for defibering the cellulosic raw material. Such a solution contains before concentration about 30 to 50 weight per cent lignin, about 5 to 20 weight per cent poly-saccharides, about 10 to 20 weight per cent mono- and oligosaccharides and about 30 to 50 weight per cent monosaccharides and lignin fragments calculated on basis of the dry matter. The pH of the ensilage feed can easily be adjusted to its most preferable value (3.5 to 4.0), while securing a sufficient amount of sugars and, thus, accurate fermentation by means of the sugars in the spent liquors.

Abstract: The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, a suitable matrix metal (33), typically in a molten state, is in contact with a suitable filler material (31) or preform in the presence of a suitable reactive atmosphere in an impermeable container (32), at least at some point during the process, which permits a reaction to occur between the reactive atmosphere and the molten matrix metal (33) and /or filler material (31) or preform and/or impermeable container (32), thereby causing molten matrix metal (33) to infiltrate the filler material (31) or preform due to, at least in part, the creation of a self-generated vacuum. Such self-generated vacuum infiltration occurs without the application of any external pressure or vacuum.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for making snow by discharging a water spray at high velosity from a first nozzle positioned adjacent the top of a tower into a freezing ambient atmosphere and further discharging a jet stream of air under pressure into the throat of the water spray thereby forming a plume of atomized water. The efficiency and capabilities of snow making are enhanced by further discharging water under pressure into the atmosphere through at least one additional nozzle, positioned adjacent to the first nozzle, in the form of an additional spray which is directed into the plume. The additional nozzle may be above, below or beside the first nozzle and if two or more of the additional nozzles are provided, they may be positioned on the same side or on opposite sides of the first nozzle, and the supply of water delivered to the discharge nozzles need not be regulated for varying subfreezing temperatures. The snow tower is preferably rotatable about a vertical axis and is also preferably bent outwardly at an intermediate portion thereof to position the nozzles further away from the base of the tower to assist in regulated placement of the snow in varying wind conditions.
