Abstract: An X-control mechanism (200) using an improved and easily installed pivot pin (100) is provided for providing a cylindrical pivot surface (16) about which a pivot arm (8) is able to pivot in response to movement of a control block (6) that is selectively engageable by a primary shaft (3) movable by an operator. The pivoting of arm (8) is operative to slide an x control yoke (14) in an opposite direction along a fixedly secured control shaft (22) for selectively engaging mainshaft gears to a transmission mainshaft 32. Pivot pin (100) is operative to hold pivot arm (8) against the transmission housing (10) between an enlarged head (12) at one end and a snap ring (20) extending radially outwardly from an annular groove (18) adjacent the opposite end.

Abstract: An incinerator (200)is provided for burning combustible refuse (16) in a primary combustion chamber (2) that has an outlet (50) for exhaust heat (30) and an inlet (28) for receiving refuse (16) and an inlet (36) for receiving a mixture of pressurized oxygen and pressurized hydrogen at respective rates correlated to create a burn temperature within chamber (2) of at least 4000.degree. F. to provide exhaust heat that is more environmentally acceptable.

Abstract: A split resilient retainng ring (100) is provided that features corresponding slots (14,16) that extend circumferentially away from each other in substantial parallel relationship to the inner periphery (4) and outer periphery (6) of the ring's body portion (2) and that end in apertures (18 and (20) respectively that have a breadth greater than the width of slots (14,16). The slots (14,16) and apertures (18,20) enable fingers (22,22') of a manipulating tool (24) to be inserted thereinto and move circumferentially away from each other along slots (14) and (16) and into apertures (18) and (20) for radially expanding and contracting ring (100) for seating in a groove. A cutting tool (800) is also provided for cutting the profiled trapezoidal configuration providing slot (14) and aperture (18) facing slot (16) and aperture (20) across the split between opposed ends (10) and (12) of ring (100).

Abstract: A hoisting sling is provided that in one embodiment (100) features a pivot assembly (4) secured to at least one end of a flexible elongate lifting element such as a cable, rope or chain. A cross bar (6) is pivotally mounted in assembly (4) and is operative to pivot to a position enabling assembly (4) to be inserted through an opening in an object to be hoisted and thence pivot so as to bridge across the opening to enable the lifting element to hoist the object. In another embodiment (150), the pivot assembly (14) features a two-piece cross bar (18 and 18') that are operative to pivot towards each other to a position enabling assembly (14) to be inserted through the object opening and thence pivot away from each other to bridge across the opening.

Abstract: An automatic clutch control system (200) is provided featuring programs for establishing optimum clutch engagement starting position (CPO) under varying operating conditions. The programs include the steps of both slow and rapid clutch engagement and preferably the storage of the (CPO) determined as a fault signal whenever its fractional relationship to the previously stored optimum clutch engagement starting position (CPN) exceeds a predetermined fraction (C6) that is less than one.

Abstract: A catapultable or rocket propelled toy helicopter (100,200) are provided that have foldable rotor blades (16 and 16') and a forwardly inclined rotor shaft surface (8) against which a rotor shaft (9) rests during flight that in combination with a balancing weight (28) enhance the spreading of rotor blades (16 and 16') at the apex of flight and the pitch and forward movement of the helicopter during flight thereafter.

Abstract: A wireless taillight system is provided having a taillight module (150) removably mountable on a vehicle such as a wagon (125) being pulled by a farm tractor (100). Module (150) has at least one signal lamp illuminable by a wireless control signal transmitter module (200) having a power source carried thereby that along with module (150) is preferably operable to transmit a feed-back signal to transmitter module (200) to provide the operator with information concerning one or more of: (i) the condition of the signal lamp; (ii) the condition of the power source powering the signal lamp and; (iii) whether a function selected by an operator has in fact occurred.

Abstract: Provided is a snap ring assembly (100) for use in holding papers together such as in a two or three-ring looseleaf notebook or binder. Assembly (100) is preferably a one-piece molded construction including an elongate base portion (30) extending between sidewalls including respective proximate sections (32, 32') extending transversly therefrom and distal sections (34, 34') that are separated by respective hinge sections (38, 38') and respective free-ends that are configured to matingly engage to cause ring sections (38, 38') to snap together to provide a closed connection when distal sections (34, 34') are pivoted for a predetermined distance toward each other.

Abstract: Disclosed are heat recoverable connectors for use as a protective covering about a plurality of joined articles such as wire splices or tubing junctures. The connectors are open-ended and feature at least one internal wall extending for at least a portion of the distance along the length of the connector to provide a plurality of open-ended channels within the connector for respectively containing one or more of the plurality of joined articles so as to insure their separation during the process of shrinking the connector by heat.
