Abstract: A process for isolating a protein fraction from an aqueous solution or suspension containing the said fraction in admixture with other substances, which comprises subjecting the aqueous solution or suspension to ultrafiltration to obtain a retentate, diluting the retentate, subjecting the diluted retentate to at least one further ultrafiltration treatment and recovering a retentate containing the protein fraction.

Abstract: A surface active compound comprises a lipophilic alkyl group linked to a hydrophilic oxyethylated group through an acetal linkage so that, on acidification of an aqueous medium containing such a surface active compound, rupture of such acetal linkage permits separation of said lipophilic alkyl group, possibly with lipid material associated therewith, from the aqueous medium in which the oxyethylated groups remain so in turn permitting recovery of such lipophilic groups and any such lipid material, and effective elimination of active surface active compound from the aqueous phase.

Abstract: An adsorbate is removed from an adsorbent by contacting the adsorbent with a supercritical fluid which is a solvent for the adsorbate. The supercritical fluid containing the dissolved adsorbate is then subjected to a physical treatment which renders the supercritical fluid a nonsolvent for the adsorbate and makes it possible to remove the adsorbate from the supercritical fluid. The supercritical fluid is then subjected to another physical treatment to restore it to a state wherein it is a solvent for the adsorbate so that it may be reused. The process and apparatus are particularly suitable for adsorbent regeneration in the treating of waste water.

Abstract: Simultaneously played notes on a keyboard are automatically provided with different voice timbres. The assignment of voices to notes is by relative frequency-scale position within the chord. If four or more notes are played, the notes are scanned along the musical scale and the three lowest notes played and the highest note are sounded in different voices with the solo voice assigned to the highest note. Assignment of voices occurs automatically when fewer than four keys are played. One form of the system combines time multiplexed keying with priority coupling of the keying information to a plurality of voltage controlled oscillators through sample-and-hold memory circuits. Each oscillator has its own tone voicing circuits. In another preferred all-digital embodiment, the time division multiplex digital logic signals representative of the played keys are applied instead to a memory circuit and a comparator circuit.

Abstract: This invention discloses an improved process for applying electrodes to the surfaces of thin ceramic discs which permits the coating of the entire disc with a conducting film and then automatically removes the conducting film from the peripheral edge of the disc as it is rolling down an inclined plane while being held within a guide slot. The bottom of the guide slot is provided with a moving abrasive belt which automatically removes the conducting film from the peripheral edge of the disc as it passes over the belt. The inventive process will permit the advantageous use of plated electrodes such as electroless nickel without entailing the costly expense of masking the edges of the discs before plating.

Abstract: Hay and similar crop materials can be efficiently compacted and formed into pellets or cubes through a closely coordinated sequence of operations in which the hay picked up from the field is deposited into a feed bin, then advanced by gravity feed uniformly onto a cross feed conveyor which advances the hay through a compaction stage in which the hay is precompressed to bale density, and thereafter it is continuously advanced between a pair of counter-rotating press wheels which further compress and form the hay into dense pellets or cubes.

Abstract: A device for and process of pre-heating the intake air of a supercharged, low-compression ratio Diesel engine when operating at low loads, comprising the apparatus for and steps of taking the heat required for said pre-heating from at least one portion of the exhaust gases of said engine and conveying it to at least one part of the intake air. The device includes heat exchange apparatus having a heating fluid inlet connected to the diesel engine exhaust line through a three-way valve, a heating fluid outlet, a heated fluid inlet, a heated fluid outlet connected to the intake air duct of the engine, and a heat conveying means moving in a closed path between the heating fluid and the heated fluid. A temperature sensor in the air intake duct controls the three-way valve to apportion the flow of exhaust gases between the heating fluid inlet and the atmosphere to maintain a predetermined minimum intake air temperature.

Abstract: The blank is made from a tube of silica with a layer of other glass coated on its inner surface. The said other glass is doped with P.sub.2 O.sub.5 for example to increase its refractive index. The blank is then reduced in diameter from a tube to a rod by heating a region of the tube while it rotates in a glassmaker's lathe. The heated region is moved back and forth along the length of the tube until it is finally reduced to a rod. One effect of the moving heated zone is to evaporate some of the doping material, and the vapour tends to move along the tube ahead of the heated zone until it is eventually shifted out of the ends of the tube. To minimize this loss the back and the forth movement of the heated zone includes a sudden step forward at the end of each pass before returning in the opposite direction.

Abstract: A uterine sound is described having a probe with measuring indicia inscribed thereon and a horseshoe-shaped body slidable along said probe and cooperative therewith for measurement of uterine position and dimension. A raised rib is located along a substantial length of the probe to normally retain the horseshoe-shaped body in parallel alignment with the longitudinal axis of the probe. When the body is displaced from parallel alignment with the probe, the rib interacts with the body to fix the body relative to the probe, and permit withdrawal of the probe and body as a unit. An internal stop mechanism is employed to prevent excessive movement of the body relative to the probe.
