Abstract: ABSTRACT OF THE DISCLOSURE:         The invention concerns a process for the manufacture of flame resistant flexible polyurethane foams by reacting a mixture of diphenylmethane diisocyanates and polyphenylene polymethylene polyisocyanates having a functionality greater than 2 containing 40 to 90 percent by weight diphenylmethane diisocyanate based on the total weight of said mixture; polyols, cyanic acid derivatives such as cyanamide, dicyandi-amide, guanidine, biguanidine, melamine, cyanuric alkyl ester-hydrazides and -amides as flame inhibitors, and blowing agents; as well as, possibly, chain extenders and other additives. The flexible polyurethane foams are suited for the familiar areas of applications, but especially as sound-insulation material for the construction industry.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for applying newsprint ink and dampening fluid to a lithographic printing plate, the apparatus comprising an ink metering roller in rolling pressure indented relation with a transfer roller having an oleophillic surface and a dampening fluid transfer roller having a hydrophillic surface each of the transfer rollers being driven by a reversible variable speed motor.  The transfer rollers are in pressure indented relationship with a form roller which transfers a thin film of ink and dampening fluid to the printing plate.          An excess of ink is supplied to the nip between the metering roller and the transfer roller to produce the thin film of ink which may be further conditioned by an ink storage roller prior to entry of the film of ink into the ink transfer nip between the transfer roller and the form roller.  By controlling the relative speeds between the form roller and the transfer roller, slippage occurs which meters a thin film of ink onto the form roller for transfer and application to the printing plate.

Abstract: ABSTRACT Metal ion impurities are removed from phosphoric acid by adding to the acid a precipitant comprising ions of clacium and fluorine to cause precipitation of, for example, a magnesium-containing precipitate.  A pre-ferred precipitant is one containing calcium fluoride, such as the sludge obtained by treating pond water from a phosphoric acid plant with a calcium-containing compound.  Preferably, the soluble sulphate content of the phosphoric acid is maintained at at least about 2% by weight.  An animal feed can be prepared from the precipitate by combining the precipitate with phosphate rock, water, and a sodium-containing compound, and then calcining the combination.

Abstract: ABSTRACT OF THE DISCLOSURE            A high power MOSFET has a plurality of closely packed polygonal sources spaced from one another on one surface of a semiconductor body.  An elongated gate electrode is exposed in the spacing between the poly-gonal sources and cooperates with two channels, one for each adjacent source electrode, to control con-duction from the source electrode through the channel and then to drain electrode on the opposite surface of the semiconductor body.  The conductive region adjacent the channel and between adjacent sources is relatively highly conductive in the section of the channel adjacent to the surface containing the sources.  The polygonal shaped source members are preferably hexagonal so that the distances between adjacent sources is relatively constant throughout the device.  Each polygonal region has a relatively deep central portion and a shallow outer shelf portion.  The shelf portion generally underlies an annular source region.  The deep central portion underlies an aluminum conductive electrode and is sufficiently deep that it will not be fully penetrated by aluminum spiking.

Abstract: DECANTING CENTRIFUGE                       Abstract A decanting centrifuge particularly useful for clinical laboratory procedures requiring the washing and packing of red cells or other particles.  An electromagnet having upper and lower planar pole faces rotates to drive a removable rotor head assembly and, during the decant cycle, holds a plurality of magnetically-attractable tube carriers in substantially vertical positions against its planar pole faces so that supernatant liquid is centrifugally discharged from the open upper ends of the tubes.  Each-tube carrier comprises a tube-holding member and a contact member, both of which have their upper end portions pivotally suspended from a support ring which is provided by the rotor assembly and which is coaxial with the rotatable magnet.  The planar surfaces of the contact members engage the planar pole faces when the centrifuge is at rest and also when the electromagnet is energized and the rotor assembly is rotated to decant the liquid contents of the centrifuge tubes.  Each tube-holding member has two outer side walls which meet along converging planes so that such walls will engage a centrifuge tube along a pair of spaced parallel lines during centrifuge operation, thereby permitting centrifuge tubes of different selected outside dimensions to be supported within the open-topped cavity of such tube-holding member.

Abstract: Apparatus and process for automating a vacuum degasification cycle for metal alloys, particularly aluminum alloys. The process comprises adjusting the degasification speed to sequentially correspond to a plurality of sets of degasification speed parameters. Each set of degasification speed parameters corresponds to a predetermined desired degasification speed. The degasification speed may be adjusted by adjusting the vacuum surrounding the alloy. The degasification speed is triggered to change from corresponding to one set of parameters to another set of parameters by the sensing of a series of predetermined partial pressures of gas in the alloy. The apparatus includes an inlet-outlet assembly for transforming given indications into a numerical form for the parameters of the degasification cycle and a calculator assembly adapted to transform the speed of degasification into variations of theoretical partial pressure and to regulate the pressure in the enclosure of the furnace to obtain an identical variation to that required based upon the indications of the standard curve placed in the assembly memories. Several furnaces may be regulated. The temperature of the metal may be regulated at a level equivalent to that required before casting. The apparatus can include a microprocessor.
