Abstract: AN IMPROVED HYDRAULIC CONTROL VALVE       Abstract of the Disclosure An improved hydraulic control valve is disclosed for providing the metering of fluid to a steering arrangement such as that normally employed on a motorized vehicle.  The steering arrangement includes a piston-cylinder assembly, a main pump for supplying pressurized fluid from a fluid reservoir to the control valve and a control pump connected to the control valve which is actuated by a manually operated steering mechanism. The improved control valve includes a housing having an elongated bore formed therein.  Movably positioned within the bore is a valve spool which has at least three annular grooves formed thereon separated by a pair of lands.  The valve spool also contains a longitudinal bore formed therein which intersects a transverse bore which opens into the centrally positioned annular groove.  The valve spool cooperates with the elongated bore to form control pressure chambers at each end thereof.  Also positioned at each end of the valve spool are check valves which are closed when the valve spool is in a neutral position and which open when the valve spool is subjected to pressure loading.  Fluid flow through the valve is directed by a plurality of passages formed in the housing.  One of the passages connects the main pump to the elongated bore, while two working passages connect opposite ends of the piston-cylinder assembly to the elongated bore approximate the outer two annular grooves which are formed in the valve spool.  There are also two control passages connecting the opposite ends of the control pump to the elongated bore approximate the pair of lands formed on the valve spool and at least one reservoir passage connecting the reservoir to the elongated bore approximately between an outer end of the valve spool and the outer annular groove formed thereon.  This improved hydraulic control valve can be used for any constant pressure system.

Abstract: PROTECTIVE PAD ASSEMBLY          ABSTRACT OF DISCLOSURE:   A protective pad assembly useable primarily by athletes to protect body parts from injury, especially from traumatic shock, as when struck by a high speed hockey puck.  The pad assembly includes a relatively rigid outer shell or shield and an inner air entrained cushion releasably attached to the outer shell and closely conformable to the body part being protected.  The cushion includes a flexible, shock absorbent pad covered by a flexible air impervious case.          The pad is formed of a soft, springy material which expels air upon compression, such as polyurethane foam.  Small openings in the case are provided for expulsion of air from the case upon deflection of the pad, as under the influence of the force of impact of an external object.  The amount and rate at which air is expelled from the case influences the resiliency and shock absorbency characteristics of the cushion .

Abstract: ABSTRACT OF THE DISCLOSURE     In a method for colorimetric determination of calcium, the sample to be analyzed is mixed with a dye reagent of pH value at which that reagent does not produce a predetermined change when complexed with calcium ions.  A first colorimetric measurement is made on the mixture of the sample and dye reagent.      A second reagent is then added to the mixture of the sample and dye reagent to shift the pH and activate the dye reagent producing the predetermined change. A second colorimetric measurement is then made on the resulting mixture.  The difference between the two colorimetric measurements is a measure of the amount of calcium in the sample.
