Abstract: An apparatus for dispensing a flowable material in a predetermined amount includes a metering wheel member for delivery of the flowable material from a supply reservoir to a dispensing port. The apparatus includes an agitator assembly mounted within the supply reservoir to maintain and promote flow of the material to be dispensed. A motive power source is provided to effect rotation of the metering wheel member and agitator assembly within the supply reservoir. Another embodiment further provides a liquid supply system for introducing liquid for rinsing or mixing. The apparatus may be further contained within a cabinet for security and maintenance.

Abstract: A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump. The coupler includes normally closed checkvalves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel. Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads. The uncoupler is structured so as to substanially eliminate the effects of fluid (e.g., gasoline) delivery pressure on the tension load required for uncoupling.

Abstract: A boat dock and lift is disclosed in which an upright frame is provided having a pair of spaced upright members and a horizontal cross member therebetween. A lift is movably mounted on the frame. The lift has a support engageable with a boat hull and a pair of generally vertical arms movably mounted on the frame uprights. A compound pulley and cable arrangement is mounted on the horizontal cross member of the frame. This pulley and cable arrangement includes a first pulley block stationary with respect to the frame, and a second pulley block movable horizontally along the cross member. A first cable is secured to the frame, is entrained around certain of the pulleys on the first and second pulley block, and is secured to one of the lift uprights. A second cable is also secured to the frame, entrained around others of the pulleys on the first and second pulley blocks, and is secured to the other lift upright.

Abstract: A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension or pressure load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump. The coupler includes normally closed checkvalves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel. Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads.

Abstract: A power broom with a transverse auger and vacuum debris conveying system especially well-suited for removing gravel or other debris from a flat, built-up roof or the like, and for conveying the loosened debris from the roof. The power broom includes a horizontal, rotary brush for dislodging gravel, dirt, and other debris from the roof and for propelling the debris within an enclosure substantially surrounding the rotary brush toward the auger which in turn positively conveys the dense gravel particles and other debris toward a vacuum pick up point within the brush enclosure where high velocity air from a vacuum source readily picks up and conveys the dense gravel particles from the power broom to a collector via a vacuum hose. The power broom is further provided with a handle assembly which is selectively operable to simultaneously disengage the power drive propulsion system of the broom and to raise the rotary brush clear of the roof.
