Abstract: An internal combustion engine ignition device of the capacitive discharge type which utilizes a single transistor, semi-conductive controlled rectifier and attendant reactive circuitry to provide timed high voltage application to create a direct current arc, or plasma, at the spark discharge devices. The circuit is actuated by closure of the contact points to energize a transistor to operate in a Class D amplifier mode that, in turn, enables conduction through the primary of a transformer, the secondary of which places increased voltage charge on a capacitor to a predetermined charge level. Thereafter, opening of the contact points causes conduction of the semi-conductive controlled rectifier which allows discharge of the charged capacitor through a current steering bridge to the ignition coil to enable application of high voltage for establishing a direct current arc, or plasma, at the spark discharge device.

Cards are provided for determining the identity and strength of each of the four playing entities, for determining the identities of opposing playing entities to be attacked, for providing defenses for each of the playing entities, and for indicating special moves for the playing entities over the game board. Playing indicia are provided for each playing area for movement between the center section and the starting and finishing spaces.
Abstract: An improved prefabricated cabinet assembly characterized by first and second precut opposite end bulkheads and one or more precut intermediate bulkheads lying in spaced, mutually parallel planes and rigidly connectable to a plurality of precut front panels lying in a common plane normal to the planes of the bulkheads. Each intermediate bulkhead is provided with clip assembly means for mutual interconnection with a corresponding one of the front panels proximate one vertical edge thereof and adjacent the vertical edge of the next adjacent front panel. Each intermediate bulkhead further includes clip assembly means for rigidly connecting the intermediate bulkhead to the front panel next adjacent the front panel corresponding thereto. Also disclosed are upper and lower precut back supports which mutually interconnect the end bulkheads and intermediate bulkheads to complete the rigid cabinet assembly.
Abstract: A road transportable apparatus for moving drill pipe and casing including a rigid support frame assembly with a bifurcated mast assembly pivotally secured thereto, the support frame assembly being rigidly securable to the walk of a conventional drilling rig pipe rack. A hydraulic power cylinder is employed to rotate the mast assembly relative to the support frame assembly. Power winches are included and operate cables extending therefrom over the outer end of the mast assembly where they are securable to the respective opposite ends of the length of drill pipe or casing suspended therebelow. A hydraulic control system is disclosed for controlling the operation of the power cylinder and the power winches. A demountable trailer frame assembly is provided for supporting the support frame assembly and mast assembly when transported over the ground.
Abstract: A chair rail which includes an elongated rigid rail member having a channel centrally positioned on one side thereof and extending over the length of the rail member, a bumper strip of resilient material slidably positioned in the channel and protruding outwardly from the rail member for protecting the rail member against shocks and impacts, and a base plate adapted to be secured to a supporting surface and having a structure associated therewith for snap on connection of the rail member thereto.
Abstract: A chain saw guard which includes a two-part base structure mountable on the housing and chain guide plate of a chain saw, and a pair of subframes pivotally mounted on the base structure. One subframe includes a pair of lateral frame members positioned on opposite sides of the chain guide plate and a third frame member positioned over the upper run of the chain, and the subframe is pivotable upwardly about an axis positioned near the saw housing to a position exposing the upper run of the blade. The other subframe is constructed similarly to the first but is positioned to protect and guard the lower run of the chain, and is mounted on the base structure to pivot downwardly about an axis positioned near the saw housing.
