Abstract: ABSTRACT OF THE DISCLOSURE           Wheat germ oil is treated by degamming with phosphoric acid and water, bleaching with activated clay and distilled in a centrifugal molecular still at 140-200°C at pressures below 50 milli-torr.  The free fatty acids which are removed by the distillation step may be recovered as valuable by-products.  The phos-pholipids removed in the degumming step may be recovered as valuable by-products.  A vitamin E concentrate may be prepared by further distilling the purified wheat germ oil at 220-300°C at pressures below 25 milli-torr.

Abstract: A B S T R A C T    O F    T H E    D I S C L O S U R E     In piston driven machines and in particular those having an elastically deformable sealing tube between the piston and the cylinder, which causes a relatively large structural length of the cylinder-piston arrangement and which may be provided with a forced feed for the lubricant, a reduction in the space requirement, in particular the structural length of the cylinder-piston arrangement is achieved by a driving mem-ber slidably mounted on a tubular cylinder externally and ex-tending over at least part of the length of the cylinder, and frictionally connected to a rotating driving mechanism.  A pulsating secondary space formed by the driving member at the outside of the cylinder is connected for the avoidance of shock pressures because of filling with lubricant liquid flo-wing away, through a balancing channel of large cross-section-al area to a pressure-balancing chamber.  For further reduc-tion in the space requirement the often necessary lubricant cooling may be effected by means of a heat exchanger to which the lubricant and the working medium of the piston machine are admitted and which is arranged advantageously inside a lubri-cant storage chamber or collector.

Abstract: ABSTRACT:                In a helical-scan video recorder a plurality of magnetic heads rotate past a magnetic tape which is guided along a substantially helical path round a tape guide member by a tape-supporting edge, the tape being transversely loaded in the direction of the tape-support-ing edge with the aid of pressure members.  The tape-supporting edge has a convex curvature with a peak sub-stantially midway between a tape-support entry point and a tape-support exit point, the curvature at the peak having a smaller radius than the curvature in the remain-ing part of the tape-supporting edge.  The pressure mem-bers are situated beyond the ends of the tape-supporting edge and the magnetic tape is curved over the tape-supporting edge in the plane of the magnetic tape in conformity with the convex curvature of the tape-support-ing edge, so that the magnetic tape is pressed against the tape-supporting edge with a transverse force which is at least approximately constant per unit of length.

Abstract: ABSTRACT OF THE DISCLOSURE         An alternating current machine drive system, com-prised of an alternating current machine and an inverter configured of a plurality of pairs of transistors with the transistors of each pair coupled in series-aiding fashion and each of the pairs serially coupled transistors connected across a direct current source, is controlled in accordance with inverter current.  The transistors of each inverter transistor pair are alternately rendered conductive to supply alternating current at the inverter output in accord-ance with a current error signal, proportional to the dif-ference in magnitude between actual inverter phase current and a sinusoidal reference signal, with the conduction state of the transistors of each pair reversing each time the current error signal exceeds an upper and lower hysteresis limit, which limits vary in accordance with actual inverter phase current.  Conditioning of inverter output voltage to control machine speed and torque is achieved by varying the sinusoidal reference signal frequency and amplitude, respectively, in accordance with operator commands.  Optimum inverter machine drive performance is achieved by regulating the sinusoidal reference signal amplitude and frequency in accordance with a feedback machine torque signal and a feedback machine flux signal, respectively.

Abstract: 48D-318 Canada SUPPORTING CAP FOR SEALED CENTRIFUGE TUBE            Abstract of the Disclosure A fluid-containing means for each bore of a centrifuge rotor is disclosed which combines a self-capped tube and a floating cap resting on the top of the tube and arranged to resist deformation of the tube by the centrifugal  forces  developed therein.   The floating cap has an annular skirt which engages the top of the tube and which is sufficiently thick in cross-section to prevent deformation of the floating cap. The floating cap is formed from a relatively light plastic, having a density less than that of the centri-fuged fluid, thereby preventing bottoming of the float-ing cap in the bore in the event of rupture of the tube.

Abstract: ABSTRACT     A grip attachment to an implement arm of construction or industrial equipment via a swivel coupling comprises three inter-digitating, articulate fingers, two pivotable about a first axis and the other pivotable about a second axis parallel to the first.          Each finger consists of a first segment pivotable about the first or second axis and a second segment pin-jointed to the first seg-ment.  Hydraulic cylinders Ire employed to cause pivotal motion of the fingers about the first and second axes, and of their second segments relative to the first segments.  An additional hydraulic cylinder acts to cause pivotal displacement of the second axis about the first axis, so that the finger pivotable about the second axis can be extended and contracted with respect to the other two fingers.
