Abstract: John D. Allen WALL STAKE FOR VEHICLE SIDEWALL PANELING                     ABSTRACT OF THE DISCLOSURE    Disclosed are wall stake structures adaptable for removable insertion into flat bed trailer and truck vehicles provided with a plurality of depending pockets whereby drayage vehicle sidewall pan-eling is supported by intervening upright wall stakes. The wall stake comprises: an upright semi-rigid post having a header and a foot which is insertable into a flat bed vehicle pocket; a plurality of distinct spacers each extending transversely forwardly of the post; and an upright guide-plate abutting the respective spacers and ultimately attached to the post, the guide-plate being transversely more resilient than is the post and also laterally liberally wider to provide two transversely resilient channels for supporting sidewall paneling. The spacers pref-erably comprise a plurality of vertically separated distinct tubular bushings which are removably attached to the post and guide-plate thereby facilitating manipulation of the paneling and permitting use of different thickness paneling.  At the header upper end of the post is provision for a secure and reliable seat to permit engagement with a transversely extending topbow canopy support.

Abstract: ABSTRACT OF THE DISCLOSURE           Electrolysis of an aqueous solution of sodium chloride is carried out employing a fluorinated cation exchange membrane having an ion-exchange capacity of 0.8 to 2.0 meq/g dry polymer and having carboxylic acid groups as functional groups and main-taining the concentration of an aqueous solution of sodium hydroxide in the cathode compartment in the range of 20 to 45 wt. % and maintaining the calcium concentration in the aqueous solution of sodium chloride lower than 0.08 mg/liter.  The purification of the aqueous solution of sodium chloride to reduce the calcium concentration is carried out in a system comprising first and second chelate ion-exchange towers which are connected through a detector for detecting impurities in the aqueous solution.  The electrolyses may be carried out at low voltage, high current efficiency and under stable condi-tions over a long period of time and is thus a satisfactory process on an industrial scale.

Abstract: Abstract A conventional crane is given added lifting capacity by adding additional counterweight to the normal counterweight while maintaining stability by adding a pair of auxiliary carbody weights on the front and rear of the carbody between the crawler assemblies.  The carbody weights have arms with lugs that cooperate with bracket lugs on the carbody so that the weights can be simply lowered into position.  There is no interference with normal operation of the crane.

Abstract: SHALLOW-HOMOJUNCTION SOLAR CELLS                         Abstract Improvements in shallow-homojunction solar cells based upon a plurality of layers of a direct gap semiconductor material such as GaAs, as well as their fabrication, are disclosed.  The shallow-homojunction solar cells have a n+/p/p+ structure in which the n+ top layer is limted to a thickness which permits significant carrier generation to occur in a lower semiconductor layer.  An anodic antireflection coating is applied over the n+ top layer, and a particularly preferred method for applying the antireflection coating is by anodization.  These solar cells can be grown on relatively inexpensive substrates, if desired, such as silicon or germanium.

Abstract: POWER STEERING GEAR WITH SHORT   PISTON AND FLUID BEARINGS                     ABSTRACT OF THE DISCLOSURE         An integral power steering gear with a valve in the piston is provided having a short piston and cylinder to conserve space and weight.  The input shaft is mounted on a bearing carried by an inwardly projecting annular portion on the bearing cap.  The projecting portion mates with a recess in the end of the piston when the piston is moved to the full extreme in that direction.  The valve guide pin has been relocated at the input shaft end of the valve where maximum support of the valve is realized and improved reversibility of the valve under all conditions is gained. In the bearing cap, both a high pressure seal and a low pressure weather seal are provided.  An insert ring between the two seals serves as backup to the high pressure seal.          In an alternative embodiment, the insert ring may be tapered toward the inside of the gear to allow use of a thin wiper-type seal.  Lubricating grooves in the piston adjacent the output rack provide fluidized bearings to counteract the force of the fluid bearing provided on the top of the piston at the pressurized input slot.  Dual feed passageways extend-ing to opposite ends of the piston have connecting ports drilled from opposite sides of the piston to add further lubrication, but also prevent cross-bleeding between the ports.

Abstract: ABSTRACT OF THE DISCLOSURE A system for the electrical treatment of spinal curvature through the exercise of selected spinal muscles.  A probe having a blunt, muscle-penetrat-ing tip is fitted with a sleeve such that its tip extends from the sleeve. A helical electrode is mounted on an elongated tool capable of imparting a rotational force to the electrode while allowing a disengagement with the electrode in the direction of its longitudinal axis.  The probe is inserted in the paraspinal muscles and is removed while leaving the sleeve within the muscle.  The electrode-tool assembly is inserted through the sleeve and the electrode secured in the paraspinal muscles by a rotational force applied to the tool.  After electrode securement, the tool is withdrawn from the sleeve and the sleeve withdrawn from the muscle leaving the electrode secured with-in the muscle.  Needle electrodes may be employed to stimulate the paraspinal muscles at several sites to establish those sites at which the induced muscle contraction provides maximum correction of the spinal curvature and the blunt probe tip may be provided with an electrode for muscle stimulation at varied penetration depths to establish the optimum depth for securement of the helical electrode.   The electrodes are connected by leads to a receiver cir-cult implantable beneath the patient's skin and operable to receive Rf modulated stimulation impulses transmitted through the skin.  The impulses are developed by a patient operated RF transmitter with a cyclic on and off stimulation and rest periods so that stimulation of the muscles may take place while the patient relaxes or sleeps.

The green-emitting phosphor component is zinc silicate activated with manganese.  The method entails  prior to mixing the phosphors together, washing the zinc silicate phosphor in an aqueous organic acid solution.   The organic acid solution consists of at least one of acetic, succinic and terephthalic.  The acid washed zinc silicate phosphor is separated from the washing solution and dried.  It is then suspended as a part of an aqueous envelope coating paint and applied to the envelope interior surface in the usual manner.

Abstract: CENTER FILLING VARIABLE    VOLUME FILM DRUM                 ABSTRACT           The present invention is directed to a variable volume film drum with a proportionally variable length conduit path for directing and controlling the flow of fluids introduced into the drum.  The center conduit path is comprised of interconnecting conduit reels also used to hold the film.  Each conduit reel has an internal conduit path, one end of which forms an outwardly extending flange or male portion and the distal end forms a receiving or female portion.  As the volume of the container is varied to accommodate more or less reels, the conduit path formed by the interconnected reels is proportionally altered.  The conduit reels are further connected to a fluid inlet tube in the film drum to complete an integral path for the introduction of fluids into the drum.
