Abstract: ABSTRACT OF THE DISCLOSURE The proposed process for the extraction of gallium from sodium aluminate liquors comprises extracting gallium from alu-minate liquors by cementation with the aid of a liquid gallium--aluminum alloy.     Should use be made of the aluminate liquors produced in the Bayer process, then, prior to cementation, these liquors are freed from various impurities. To this end, the recycle aluminate liquor is cooled to a temperature at which the soda crystallizes and the vanadium is retained in said liquor, wher? upon the crystallized precipitate is separated, while the resi? dual liquor is mixed with the mother aluminate liquor in the ratio of 0.1-1 to 1-0.1. The resultant liquor is cooled down to ambient temperature, and the vanadium precipitate is separa? ted.      The process of the invention is a major step towards a si? pler technique of gallium extraction from aluminate liquors both high and low on gallium. Besides, the process of the in-vention permits extracting, directly from aluminate liquors, gallium in a higher degree of purity than can be obtained in the prior art.      Furthermore, the process of the invention enables valuabl? vanadium compounds to be recovered from liquors alongside gall? um.

Abstract: ABSTRACT OF THE DISCLOSURE          A differential pressure sensing device is fully implanted in the body of a patient to monitor internal pressure such as intracranial pressure.  A movable element in the sensor communicates on one side with the internal pressure to be measured and on the other side with an external pressure which is applied by an external pressurizer-control system and which is communicated to the sensor through the intact skin.   An imbalance of the two opposing pressures causes a displacement of the movable element which changes a physical characteristic of the sensor, such as the resonant frequency of a tuned L-C circuit.  This change is detected outside the body by an external detection system, such as a frequency swept radio frequency oscillator. The external pressure is varied until the external detector senses that the pressure are balanced on the movable element, at which point the external pressure equals the internal pressure, and the former is measured and read out.   1.

Abstract: SPOOL VALVE FOR HYDRAULIC BRAKE BOOSTER       ABSTRACT OF THE DISCLOSURE A hydraulic brake booster includes a spool valve within a housing for communicating fluid pressure into a chamber for urging a piston in a direction actuating a master cylinder, thereby effecting a brake application. The communication between an inlet passage and the chamber is regulated by a land on the spool valve cooperating with a corresponding land on the housing.  In order to prevent particles which are carried in the pressur-ized fluid from wedging in the interface between the land and the corres-ponding housing land, an additional land is provided on the spool valve. The additional land cooperates with another land on the housing to form a small clearance therebetween so that large particles in the fluid are pre-vented from wedging in the interface between the sensitive land and the corres-ponding land on the housing when the valve is in the brake-released position.

Abstract: ABSTRACT OF THE DISCLOSURE     A repeating hemostatic clip applying instrument and multi-clip cartridges therefor is generally shaped and operated in the manner of prior clip applying instruments.  Shaped like a pair of dog-nosed pliers, the other ends of the jaws are adapted to hold a clip which may be applied to a blood vessel with the instrument.  The rearward portion of the jaws overlap and a rectangular channel is formed in one of them through which clips may be pushed by a pusher extending down the center line of the instrument.  One of the jaws is adapted to receive a cartridge containing a stack of U-shaped clips which may be pushed one at a time to the distal end of the jaws by the pusher.  The instrument basically comprises only three pivoted members, the pusher and its operating linkage, and one or two springs.  Several forms of pusher-actuating means are disclosed, two of these include a bell crank and cam so that the pusher will be operated before the jaws can be closed. The third comprises a free bell crank and a pair of unbalanced springs to achieve the same object.  The cartridge is provided with a spring for urging the U-shaped stack of clips down to the pusher channel, and a clip follower for preventing misalignment of the clips in the cartridge.  These above and various other features operate together in a synergistic manner to apply a plurality of hemostatic clips in a surprisingly simple, light instrument providing an almost conventional "feel".
