A truck tailgate assembly is provided including an inboard portion adapted for being pivotally mounted on a rear edge of a truck. Also included is an intermediate portion being hingably mounted to the inboard portion. Next provided is an outboard portion which is hingably mounted to the intermediate portion. A locking assembly is adapted for maintaining the portions in stacked relationship while the truck is moving.

Foldable tailgate

A direct melt spinning process for providing high filament count fine filament polyester yarns having excellent mechanical quality and along-end uniformity and unitary interlace by spinning all the filaments of such high filament count yarn from a single spinneret. Such yarns may be used as direct-use yarns and as draw-feed yarns for preparing drawn flat yarns and draw-textured yarns.

Polyester mixed fine filament yarns having excellent mechanical quality and uniformity, and preferably with a balance of good dyeability and shrinkage, are prepared by a simplified direct spin-orientation process by selection of polymer and spinning conditions.

Polyester mixed yarns with fine filaments

A post-coalescence melt-spinning process for preparing fine undrawn hollow polyester filaments having excellent mechanical quality and uniformity at high speeds (2-5 km/min) involving selection of polymer viscosity and spinning conditions, whereby the void content of the resulting new undrawn filaments is essentially maintained or increased on cold-drawing or hot-drawing with or without post heat treatment, and the new fine hollow polyester filaments obtained thereby.

A vehicular battery charging switch comprising a tubular vial having a front end, a rear end, and a small amount of electrically conductive liquid material disposed therein; a coupling mechanism for coupling the vial to a vehicle such that its front end is positioned below its rear end when the vehicle is positioned on a level grade; and a pair of electrical contact pins coupled to and extended within the front end of the vial with one contact pin adapted to be connected to an alternator and the other contact pin adapted to be connected to a voltage regulator that is associated with a battery; whereby when a vehicle is travelling on level-grades and on down-grades, the front end of the vial is held below the rear end thereof such that the conductive liquid material is placed in contact with the contact pins, thereby connecting the alternator with the voltage regulator and allowing charging of the associated battery, and when a vehicle is travelling on up-grades, the front end of the vial is tilted above the rear end thereof such that the conductive liquid material breaks contact with the contact pins, thereby disconnecting the alternator from the voltage regulator and preventing charging of the associated battery.

Polyester fine filaments

A vending machine including a plurality of receptacles in which articles to be vended are stored and releasing mechanisms that selectively release the articles from the receptacles. An enabler counts money or other tender deposition in the machine and enables the releasing mechanisms associated with those receptacles containing appropriately priced articles as successive predetermined totals are reached. The money is temporarily deposited in an escrow chamber from which it is released into a bank only after a sensing device determines that an article has in fact been released.
