Abstract: ABSTRACT OF THE DISCLOSURE           A device for controlling hydraulic distributors in a suspender of hoisting means, comprising a closed casing filled with a liquid substance and containing a ball, the casing being mounted to tilt about a pivot fixed to the suspender frame, a stop being provided for controlling at least one of the hydrau-lic distributors.  The closed casing has a bottom which is flat and is provided with two adjustable horizontal guide rails for the ball.  Each of the guide rails is connected to the bottom of the casing by means of a vertical pivot.  At least one end of each of the guide rails is coupled with the corresponding end of the other guide rail by means of a tension screw the position of which is determined by a link fixedly attached, to the inside wall of the closed casing facing the ball, while a vertically oriented adjustable elastic dog is secured to the outside wall of the casing opposite the inside wall.  This device can be used in all cases where the necessity of espe-cially repeated manipulation of loads, the centre of gravity of which is beyond their axis of gravity, occurs and where a quick, safe as well as often considerably accurate balancing of loads to assume the horizontal position, is desired.

Abstract: ABSTRACT OF DISCLOSURE     A nail, especially suitable for use with magazine-fed nailing machines, comprises a shank of oval cross-sectional shape and, at one end thereof, a head.  The head projects transversely to the shank except at one side at least thereof, specifically at a position of intersection of a minor axis plane with a notional geometric extension of the shank periphery.  Such a head configuration allows a plurality of the nails to be collatad in a strip, with their minor aces aligned with the plane of the strip, for use with a magazine-fed nailing machine.  In a so-called "T" headed nail, the head comprises an elongate portion having limbs projecting from the shank in the direction of the major axis.  In a so-called "D" headed nail, the head is an incomplete disc configured to permit collation of a plurality of the nails with shanks abutting and heads overlapping in stepped relation.   In a preferred method of making the nails the end of the shank is projected into a slot wherein it is upset by a suitable punch.

Abstract: "CHROMATE REMOVAL BY PRECIPITATION"           ABSTRACT OF THE DISCLOSURE Chromates are removed from aqueous alkali metal chlorate solutions by either of two processes. In the first process, a water-soluble sulfide such as NaHS is added to the chromate-containing chlorate solution, at a temperature of about 40-60°C and at a pH of 7-8, in an amount ranging from 70-200% (and preferably, 100%) of the stoichio-metric value required to react with the chromate; and then a water-soluble ferrous salt (preferably FeSO4) is added in an amount of from 30-100% (preferably about 57%) of the stoi-chiometric amount required; and the pH of the solution is adjusted so that the final pH is in the range of about 1.8 to about 3Ø  The soluble sulfide is converted to elemental sulfur and the chromate is converted to an insoluble, tri-valent Cr-containing material, which is subsequently removed from the solution.  The low pH of the filtered liquor renders it particularly suitable for use in a chlorine dioxide generator.  In the second process, the pH of the chromate-containing chlorate solution is first adjusted to a value within the range of 7-11, and preferably to about 11, and the solution is heated to a temperature of 40-60°C.  An "iron mud" is prepared by reacting a ferrous salt, e.g., FeSO4, with sodium hydroxide in  molar  proportions of 1 part ferrous salt to 1.5-1.8 parts of NaOH, the amount of ferrous salt employed being from about 3 to about 5 times the stoichiometric amount required to reduce the chromate present in the solution.  Then the "iron mud" is added slowly to the chlorate solution with vigorous agitation, and the pH is controlled to a value within the range of 10-12.  The insoluble trivalent chromium-containing material so formed is subsequently removed from the solution.  This invention is effective in removing chromates from alkali metal chlorate solutions having a NaClO3 con-centration in the range of 600-750 gpl, at which concen-tration previous processes for the removal of chromates are largely ineffective.

Abstract: S P E C I F I C A T I O N             "Fitments for Injection Devices"                 ABSTRACT OF THE DISCLOSURE           In order to minimise the risk of infection when a large number of animals are injected with the same needle, the injecting gun is provided with a stainless steel sleeve which surrounds the needle. The sleeve comprises a first tube attached to the needle connecting body and a second tube telescopically slidable within the first tube against a spring.  A detachable plastics cap incorporating a sterilising substance is fitted on the free end of the second tube. In use of the gun to inject an animal, the cap is applied to the proposed site of injection and pressure is applied to the gun to cause the tubes to telescope, so that the point of the needle passes through the sterilising substance and punctures the skin of the animal. On releasing the applied pressure, the point of the needle will be withdrawn from the animal and will pass back through the sterilising substance under the action of the spring.

Abstract: ABSTRACT:                 An arrangement for adjusting the value of an electrical component, for example a potentiometer, by means of rotatable shaft comprising first and second pulleys and a cord passed round the pulleys in a figure of eight configuration.  A control lever is movable through a first angle, typically 60°, and is effective to rotate the shaft of a potentiometer through 300°.         The first and second pulleys are arranged with their rims in contact at point so that side thrust on the potentio-meter spindle caused by the tension in the cord is resisted by the contact between the pulleys.  In order to prevent slip between the cord and the pulleys the cord is clamped on each pulley and the ratio of the rim radii of the pulleys is made equal to the ratio of the core radii of the pulleys.         The arrangement may be used in television studio and outside broadcast equipment such as video tape recorders, special effects generators and remote controllers.
