  • Publication number: 20020175526
    Abstract: A specialized tool for utilization within the chute of a concrete truck enabling efficient direction of liquid concrete via a raised gripping edge and strategically shaped, replaceable/disposable head, wherein a generally semi-circular shaped head facilitates compatibility with the discharge chute of a cement truck for assisting in the direction and placement of concrete, a gripping edge facilitates a comfortably secure reach into the discharge chute of a cement truck for scooping, pulling, plugging or otherwise controlling the flow of concrete and a replaceable blade head provides long-term efficient usage thereof, thereby enabling a user to efficiently deposit, apply and manage fresh liquid concrete from a concrete truck's chute as the concrete is being discharged.

  • Patent number: 6318103
    Abstract: The present disclosure relates to electrical component heat dissipation and, more particularly, to a method and apparatus for dissipating heat from a power control module. In one embodiment the invention is a power control module having a housing and an electrical connection. A thermally conductive material is placed between the power control module and a surface of an evaporator core with a first side of the thermally conductive material in contact with the power control module and a second side in contact with the surface of the evaporator core. The thermally conductive material conducts heat from the power control module to the surface of the evaporator core.

  • Patent number: 6074294
    Abstract: An automotive air conditioning system mode control film belt that uses a single drive shaft to shift the belt back and forth. The belt follows a continuous loop that begins and ends at the single drive shaft, wrapping around idler rollers, where necessary, to maintain defined runs of the belt against one or more vent windows in a housing. Thin, long, and widely spaced pairs of drive bands at either end of the belt wrap around the single shaft in opposite directions, clear of one another, wrapping or unwrapping from the shaft in opposite directions as it turns in either direction. The belt is thus able to shift back and forth to open or close the vent widows, while air is able to flow unobstructed between the widely spaced belt drive bands and out to the vent windows.

  • Patent number: 5025772
    Abstract: A bowstring release device is disclosed which provides greater ease, control and accuracy in the shooting of a bow and arrow. The structure and action of the device inhibits and prevents premature release of the bowstring while being drawn, and enables a smooth, natural and accurate release once the archer has taken aim. The device includes a housing having two members. One member contains holding and release means for the bowstring while the other member includes finger recesses for gripping by the archer. The two members naturally assume a first position relative to one another while the bowstring is being drawn, and this first position prevents release of the bowstring. Once the bowstring is drawn, the archer effectuates release by pivoting the finger grip member of the housing relative to the release member.
