Abstract: Abstract of the Disclosure.           An elongated decorative moulding suitable for use with automotive vehicles has a core portion of foamed plastic, and an outer portion of solid material such as a laminate secured thereto, to provide a finished coloured surface of enhanced appearance and durability.  The use of a foamed core material such as foamed soft polyvinyl chloride reduces the mass of plastic required by a signi-ficant amount, and modifies the flexibility and impact characteristics favourably, while the use of a skin layer such as a laminate secured thereto permits the core material to be unpigmented, for significant savings.

Abstract: ABSTRACT OF THE DISCLOSURE A belt, band or other tire component folding machine and method are characterized by a rotatable and expandable drum comprising a substantially rigid cylindrical deck having a precisely formed peripheral deck edge and an inflatable bladder assembly positioned slightly axially and radially inwardly subjacent the deck edge which cooperate to define a precise fold line along the deck edge at which a ply or belt band or the like is precisely and sharply folded. Preferably, dual inflatable bladders are employed at each end of the deck, one bladder being contiguous to the other and arranged on inflation to walk up the precisely formed and contoured deck edge to turn up the overhanging band end, and the other arranged to push the first bladder axially inwardly to complete the fold of the band flat upon itself. A preferred form of deck comprises a plurality of readily replaceable segments which are mounted in a self-aligning manner on a radially expandable and rotatable hub. Each segment includes a pair of interfitting outer deck sections which are movable axially of the drum towards and away from each other to expand and contract the width of the deck in precise increments. Various forms of the deck further comprise spring gap shields or elastic gap spanning bands which circumscribe the deck at the deck edges. The various components are readily interchangeable with components of different sizes and adjustable to accommodate different sizes of tire components.

Abstract: Improvements are provided in a sprinkler head assembly including a hollow sprinkler head assembly tube, a sprinkler tip secured in the upper portion of that tube and a valve secured in the lower portion of the hollow sprinkler head assembly.  The means for retaining the sprinkler tip within the hollow sprinkler head assembly is a securing structure which depends from the sprinkler tip, (e.g., a central tube having an internally threaded bore, the tube having a slit through the walls at its lower end forming bifurcated portions provided with a pair of wings, each having an upwardly facing abutting shoulder thereon), retainers within the upper portion of the hollow sprinkler head assembly on its inner wall, (e.g., a downwardly facing abutting shoulder spaced downwardly from the upper end of the tube) and an actuator for urging the securing structure into engagement with the retainers (e.g., a screw engaged within the bore which when screwed downwardly, spreads the wings, thus engaging the wing shoulders under the tube shoulders and securing the tip body portion in position).  By suitable adjustments, the position of the valve relative to the seat is controlled, thus controlling the amount of water passing through the valve between the valve head and the seat.

Abstract: ABSTRACT OF THE DISCLOSURE:     A competitive amusement game apparatus in which a player selectively moves a playing member pivotally mounted on a base housing toward an opposing playing member in an effort to strike the head of the opposing playing member.  Each of the playing members includes a pair of arms pivotally connected to a body and having a head releasably attached to and positioned on the body.          A shield is connected to the outer end of one of the arms and a hammer is connected to the outer end of the other of the arms for each of the playing members.  The hammer of one playing member will strike the head of the opposing playing member to disengage the head of that playing member if the shield of the opposing playing member is not in position in front of the head.  If the shield of the opposing playing member is in position, a hammer when moved toward it will simply strike that shield and not reach the head of the opposing playing member.  A manually-operable actuating mechanism is operatively connected to each of the play-ing members for selectively pivoting the arms of each of the playing members for moving the shield of the playing member down-wardly and the hammer of the same playing member toward the other opposing playing member for hitting, and thereby releasing the head from the body of the opposing playing member.

Abstract: ABSTRACT OF THE DISCLOSURE A syringe comprising a cylindrical barrel with a wall at one end with a nozzle and with a threaded actuating rod ex-tending from its other end. The rod has a piston at the end thereof within the barrel, the piston being in fluid tight engagement with the inner wall of the barrel, and has a knob at its opposite end for rotating the rod. The rod also carries a collar with threads which mate with the rod threads, and the collar has slots which engage projections on the barrel and prevent movement of the collar relative to the barrel but which permit the collar to be disengaged readily from the bar-rel. Rotation of the rod causes movement of the piston axially of the barrel when the collar is engaged, but the rod can be moved axially without rotation when the collar is disengaged.

Abstract: ABSTRACT OF THE DISCLOSURE           A wheeled vehicle mounts a rotary framework pro-viding a plurality of longitudinally extending, peripheral and inner compartments for the removable storage of a mul-tiplicity of hay bales or like objects. The framework is rotated by a driven endless chain wrapped about the frame-work centrally of the longitudinal ends thereof. Communi-cation between the peripheral and inner compartments is con-trolled by movable gates operated selectively by spring-loaded latching mechanism at predetermined intervals of rotation of the framework. A longitudinally extending, re-versibly movable feed conveyor below the framework regis-ters with each of the peripheral compartments selectively for moving bales to and from the compartments. The arcuate shields extend from the opposite sides of the feed conveyor upwardly to form with the latter a semi-circular shield surrounding the lower half of the framework to confine the bales in the lower peripheral compartments. A forwardly ex-tending, reversibly movable delivery conveyor is aligned with the feed conveyor and is adjustable pivotally to lower its forward end for picking up bales from the ground and delivering them to the feed conveyor, and to raise its for-ward end for delivering bales from the feed conveyor to a storage conveyor for moving bales to storage.

Abstract: SCREW PRESS WITH CONTINUOUS SLOPE FEED SCREW      Abstract A screw press for extraction of liquids from solids or semi-solids haying a feed screw (22, 24) disposed in a cylindrical cage (41) formed from filter screens (42).  The feed screw has a body portion (22) that increases in diameter over the full length of the screw in a linear fashion forming a gradual slope providing a gentle pressing action on the materials being pressed.  A variable speed drive (60) is used to optimize the rotational speed of the feed screw for maximum liquid extraction versus material throughput.  The cylindrical cage (41) comprises at least-one pair of semi-circular sections connected along a lower edge by a set of offset hinges (46) and bolted together along an upper edge.  For cleaning of the press or changing of filter screens, the sections open with the off-set hinges causing the sections to move downward and outward, completely clear of the feed screw.  The screw press is especially suitable for predraining of grape must prior to final pressing, dejuicing fragile fruits such as apples, and dewatering of materials having a high  liquid content.

Abstract: ELECTRICAL CONNECTOR CONSTRUCTION            Abstract of the Disclosure An electrical connector for terminating pairs of conductors on individual single electrical, insulation piercing contacts.  The connector is formed as two housing halves fitted to a central spacer member to which both are locked.  The contacts are mounted in the housing halves and each presents at one end a conventional terminal pin receptacle comprising a pair of opposing blades.  Toward its other end each contact is formed to present a pair of inverted "U" shaped members which are slotted to accomplish the conductor insulation piercing function.  The members, although equally spaced on the contacts, are staggered in their positions on the contacts with respect to both adjacent contacts within a housing half and adjacent contacts between the housing halves.  As a result, when the latter elements are assembled, an insulation piercing member of one housing half will extend between the pair of members of the other housing half.
