Abstract: A hand crank device and associated method for winding winches such as those used on flat bed tractor trailers. The hand crank device includes an elongated pin element that is sized to engage the drive shaft of a winch. The pin element is long enough to enter through one hole on the drive shaft, extend across the drive shaft and exit the drive shaft through a second hole on the opposite side. The pin element is affixed to the short arm section of an L-shaped bracket. A handle is affixed to the long arm section of the L-shaped bracket, thereby enabling a torque to be applied to the L-shaped bracket and the pin element affixed to the L-shaped bracket. The torque acting on the pin element is transferred to the drive shaft of the winch, thereby causing the drive shaft to turn and the winch to rewind.

Abstract: An apparatus for resisting coagulation of blood, includes a blood container having disposed therein antibody to blood coagulation factors for resisting coagulation of blood. The apparatus further includes a needle and a holder for the needle which are both operatively associated with the blood container. The blood coagulation factor antibody inhibits coagulation of the blood drawn by the needle into the blood container so that an uncoagulated blood sample is obtained.

Abstract: A hypodermic needle assembly adapted for covering and uncovering the needle by relative lateral movement between a closure member and the needle. The needle has an enlargement hub portion. An elongated closure is disposed in adjacent relationship with respect to the needle and has an elongated slot which permits insertion of the needle into the closure and removal of the needle therefrom. The closure may engage the needle hub for resisting undesired removal of the closure. A closure strip is displaceably secured in overlying relationship with respect to the slot so as to provide a sterile needle. Pilot means may be provided adjacent the closure slot to facilitate insertion of the needle into the slot. An indicator may be provided to facilitate determination of closure orientation.

Abstract: A pick and place mechanism is provided for selecting a part from a pick-up location, transporting the same to a place location, and placing it in a precise position at the place location. A part is engaged by a pair of gripping fingers which depend from a casing mounted for movement between the pick and place locations. The fingers are connected to a cam mounted for reciprocation in the casing to alternately extend and retract the fingers. The fingers cooperate with an actuating mechanism carried by the casing to engage and disengage the part in response to movement of the cam. The cam is normally biased upwardly and is actuated by a follower which is guided in a slot in the casing, and an air cylinder drives the follower and hence the casing between the pick and place locations.
