Abstract: This invention is a connector tool apparatus used to attach a hanger clip to a ceiling T-bar member and connect a light fixture to the hanger clip. The connector tool apparatus includes a handle assembly integral with an actuator assembly. The handle assembly includes a main body resembling a screw driver handle connected to a clip connector assembly. The clip connector assembly includes a connector coupling having a central threaded hole to receive a threaded shaft of the hanger clip therein during use thereof. The actuator assembly includes a U-shaped connector arm with parallel arm sections, each integral with a connector head of conical shape. The connector heads cooperate to rotate a connector nut of the hanger clip during assembly thereof.

Abstract: This invention is an ellipsograph drafting apparatus operable to draw ellipses of any desired ratio of major and minor axes limited only by practical size of the device. The ellipsograph drafting apparatus includes a main support means, an elliptical control means, and an intermediate connector means connecting the elliptical control means to the main support means. The elliptical control means includes a marking instrument and actuator assembly which is operable to draw ellipses on a support surface through preselected movement of a pivot arm and slide assembly in a three dimensional manner.

Abstract: This invention is a coin operated vacuum apparatus including a housing means mounted on basic support means; a vacuum power means enclosed by the housing means; a coin control means connected to the vacuum power means to control operation thereof; and a hose assembly connected to the vacuum power means. The housing means is constructed of fiberglass material having a cover head assembly and a removable receptacle assembly to receive refuse material therein. The vacuum power means includes a filter and motor assembly having a pair of vacuum motor members mounted on a motor head support assembly with the entire unit easily removable for maintenance purposes. The filter and motor assembly includes a filter assembly associated with each vacuum motor member to provide efficient filtration. The coin control means includes a time meter assembly to be actuated by a coin for a predetermined time period to energize the vacuum power means.

Abstract: This invention is a mini-dome basketball game including an enclosure structure resembling a basketball court having an actuator structure with a plurality of actuator flipper members operable to contact a ball member to propell the same upwardly and forwardly towards a basket member to simulate a basketball game. The playing area is enclosed by a clear plastic dome to maintain the ball member therewithin and includes a score device mounted on the enclosure means operable to keep score between the players similar to a regulation basketball game. The actuator flipper members includes one for each of the two players and a third free-throw zone to propell the ball member toward the basket member in free-throw situations.

Abstract: A power cultivator apparatus being a self propelled device having structure for supporting a tool member thereon for earthworking operations in a limited space or area requirement such as cultivating a single row at a time. More particularly, the power cultivator apparatus provides a power assembly mounted on a support and guide assembly; a tool member connected to the support and guide assembly for earthworking purposes; and a control assembly having foot actuated members operable to 1) raise and lower the tool member; 2) operate a transmission assembly; and 3) raise and lower front forward lateral support wheel assemblies for ease of operation.

Abstract: This invention is a trigger release mechanism usable with a bow and arrow assembly being initially operable 1) to grasp the bow string to pull the same backwards and then 2) to instantaneously and accurately release the bow string through operation thereof. The trigger release mechanism includes a housing assembly; an actuator assembly operably connected to a cam assembly with both mounted within the housing assembly; and an adjustment assembly mounted within the housing assembly. The actuator assembly includes a plunger member operably connected to a main actuator member which, in turn, is operably associated with the cam assembly. Axial movement of the plunger assembly permits rotation of the cam assembly to release the bow string. The adjustment assembly is operable to adjust 1) the resistance to axial movement of the plunger member and 2) amount of axial movement of the plunger member required before release of the bow string through the cam assembly.

Abstract: An electrical brake control system for a towed vehicle having an electric brake, where the control system is actuated by the hydraulic brake system in the towing vehicle. The electrical brake control system includes a hydraulic pressure transducer having a hydraulic input connected to the hydraulic brake system of the towing vehicle and an electrical output proportional to the hydraulic pressure developed by the hydraulic system. A comparator circuit has first and second inputs and an output. A circuit connects the first input to the electrical output of the hydraulic pressure transducer and a second circuit connects the output from the comparator circuit to the electrically operated brake in the towed vehicle. A feedback system connects the electrically operated brake to the second input of the comparator circuit such that the comparator circuit always maintains the feedback voltage to the second input substantially identical with the voltage of the first input.

Abstract: This invention relates to a compact evaporator cooler apparatus having a vaporizer means mounted within a housing means and a fluid supply means connected to the vaporizer means for the mixing of air and water to thoroughly saturate the air. The vaporizer means includes a power assembly having a motor member with a central shaft to drive a vaporizer disc on one end and a fan blade at the other end to achieve a thorough vaporization or fogging of water particles discharged outwardly from the vaporizer disc. The vaporizer means further includes a filter assembly having a filter member operable to filter the air therethrough and permit the cooled air to pass therethrough to the area to be conditioned.

Abstract: This invention relates to an emergency illumination system which is attachable to a fender portion of a vehicle and operable to both light the area adjacent and about the wheel structure plus outwardly therefrom to aid in changing a flat tire and illumination during emergencies. The emergency illumination system in one embodiment includes a lighting means having a light assembly attached at each fender portion and operable through an electrical means to either (1) illuminate all the wheel well areas by turning on an emergency flasher system of the vehicle; (2) operate a special switch on a turn indicator member to energize all of the light assemblies; and (3) having a switch member operable to be connected with the respective turn indicator lights so as to illuminate the forward ones of the light assemblies for reading house numbers and aid visually when turning corners. The emergency illumination system can be used for clearance lights on trucks, campers, etc. and constructed of various colors.
