Abstract: PICKUP ARM ASSEMBLY                  Abstract of the Disclosure A pickup arm has an intermediate portion inter-connecting a first end portion and a second end portion.          An end of the first end portion is secured to a supporting structure of a disc record player.  During playback the first and second end portions are substantially parallel to the turntable surface of the player, and the intermediate portion positions the second end portion near the turntable surface.  A signal pickup holder carrying a signal pickup is pivoted to an end of the second end portion remote from the pickup arm supported end in a manner that normally aligns the axes of the holder and the second end portion.  During playback the intermediate portion positions the second end portion remote end, carrying the signal pickup holder pivot, as near to a disc record disposed on the turntable surface as practicable, in order to reduce the angle included between (a) the disc record surface, and (b) a line joining the signal pickup tip and the signal pickup holder pivot, thereby reducing deleterious, forward and backward displace-ment of the signal pickup along the disc record spiral groove as a result of up and down motion of the signal pick-up in the spiral groove.

Abstract: ANTI-LUMPING COATING FOR POLYSTYRENE BEADS            ABSTRACT OF DISCLOSURE       A complex is formed by the reaction of an aluminum salt such as aluminum sulfate with a high molecular weight (for example, above 60,000 M.W.) collagen.  Collagen-aluminum complex is dispersed in water and serves as suspen-sion agent for suspending polystyrene beads during impre-nation of a blowing agent, even when the concentration of the suspending agent is of the magnitude of 0.05% by weight of the beads.  The aqueous system is drained from impregnated expandable beads, which are washed, but which retain adherent deposits of said collagen-aluminum complex in measurable amounts.  The dried coated beads have mini-mized propensity toward lumping when pre-expanded.  The prepuffed particles can pass tests concerned with resist-ance toward static electrical phenonomen better than corresponding prepuffed particles lacking such deposit of collagen-aluminum complex.   1.

Abstract: HIGH PRESSURE COUPLING APPARATUS                   Abstract of the Disclosure Concrete pumping conduits are connected by releasable hinged couplers.  The ends of the conduits include metal pipes formed with annular grooves including a circular peripheral base and a stepped and wall immediate adjacent the end of the pipe to define a pair of generally parallel and radially extended, in-clined sidewalls.  The coupler is formed with inwardly projecting legs with the inner walls similarly stepped and defining a pair of generally inclined radial sidewalls offset in accordance with the offset of the grooved sidewalls, but slightly less than such spacing.  A sealing gasket is located within the base of the cup-shaped recess with a tongue-like ridge projecting between the two end faces of the pipe ends.  The first radially outermost side-walls of the coupler and the radially innermost sidewalls of the groove engage upon closing to provide a mechanical connection. The gasket is collapsed to seal the joints.  The inner secondary, coupling sidewalls of the coupler and pipe grooves are spaced slightly from each other in the closed position.  If the first sealing walls breakdown or roll over, the secondary sidewalls move into engagement resulting in a continued operable coupling. The gasket is recessed adjacent the ridge to define adjacent chambers with the outer sidewalls to define lips in sealing en-gagement with the conduit.  The peripheral ends of the pipes are chambers and engaged by the sealing lips.

Abstract: IMPROVED HOUSING ASSEMBLY FOR MINIATURIZED    BATTERY OPERATED ELECTRICAL APPARATUS                             ABSTRACT      An improved housing assembly for housing miniaturized electrical or electronic apparatus, such as a radio receiver or monitor, is disclosed wherein a single piece housing is provided, open at the top for receiving an associated elec-trical chassis with self-contained battery compartment and a sound transducer.  A control panel attached to the electrical chassis cooperates to overfit the open end of said housing to complete the overall assembly.  The assemblage of the housing apparatus requires no screws, fasteners or special tools as the respective component parts effect a snap-fit with one another.  A novel interlocking arrangement between chassis assembly and housing disguises the latching interfit therebetween, which nevertheless may be released by the insertion of a simple blade tool at the proper location.          Complete shock mounting and protection from dust and dirt is effected by resilient gasket elements in cooperation with the housing and chassis assembly.  A transparent lens cover is incorporated on a portion of the bottom panel to overlie an information placard referencing operational data but which, in addition, includes features which show if unautho-rized access has been effected to the internal chassis assembly.
