Abstract: A motor mount having first and second mounting surfaces with at least three mounting elements fixed therebetween is used to absorb motor vibration and shock impulses which are produced primarily parallel with the plane of the mounting surfaces. Two of the three mounting elements are dampers which flexibly connect the first mounting surface in a parallel relation with the second mounting surface. The third mounting element maintains a preferred range of distance separation between the mounting surfaces to that a damping flexion potential of the dampers is maintained.

Abstract: A Marine Jet Propulsion System for use as an inboard engine for boats is herein described. An engine or motor means is attached in a driving relationship to a pump and thrust output apparatus. Heat generated by and rejected by the engine or motor is passed into the pump base for dissipation into the outputted jet thrust stream. Air and/or exhaust gas from the engine is ejected around the jet output stream to reduce against-the-hull turbulence and jet stream or thrust energy losses. Streamlining hull closures for the jet pump intake and output ports are provided to reduce system hull drag when not in use and to limit marine organism growth inside the pump.

Abstract: Slip mechanisms for selectively gripping and releasing conduit in a well drilling operation, particularly useable as elevators or spiders. Three slips are positioned within a tapered bore of the slip mechanism having a split front opening, and are articulatingly suspended from a vertically movable ring. Upon lowering of the ring the slips move downwardly and inwardly along the tapered bore to simultaneously and evenly grip the conduit. Upon raising of the ring the slips move upwardly and outwardly along the tapered bore and disengage from the gripped conduit. In the disengaged position two of the three slips are circumferentially slidable, through the suspension connection to the ring, to a position spaced from the front opening and adjacent the third slip, whereby the slip mechanism is laterally movable from, or about, the conduit. A funnel shaped guide skirt is mountable on the bottom of the mechanism when operation as an elevator is desired.

Abstract: A turn signal light housing has a translucent lens of arrow shaped configuration mounted on the housing in place of conventional circular lens without any need for modification of the housing.

Abstract: Intake fuel supplied to a conditioning tank is mixed therein with engine heated fuel returned from a fuel injector to which mixed fuel from the tank is fed.

Abstract: A rotary tong for use in well drilling operations to make up and break out drill strings or similar axially elongated objects which has a secondary camming action provided by the jaw assembly. By use of the inventive jaw assembly a secondary camming action is produced which reduces the cam angle of the primary camming function. The reduced cam angle gives greater gripping force thereby reducing slippage. The secondary camming function also allows the jaw to be used for a greater variety of drill string sizes thereby reducing the need to change tongs or jaw elements when drill string sizes change.

Abstract: A prosthetic cement spacer for controlling the thickness of cement applied between a prosthetic insert and a support member, such as an acetabulum, includes a generally cylindrical standoff body portion fabricated from acrylic bone cement and a pointed wire concentric with said standoff body and outwardly extending from one end a sufficient length to anchor into the acetabulum bone surface. The method of use of these prosthetic cement spacers involves preparation of the acetabulum so that there is sufficient clearance space for the prosthetic cement spacers and then to insert the pointed wires into the acetabulum bone surface in an equilateral triangular arrangement thereby providing three points of contact for the prosthetic insert, such as an acetabular cup.

Abstract: A putter uses an angled mirrored upper club surface with a deeply scribed and pigment filled line to act as a sighting device. In one embodiment, a clear plastic block has a bottom surface coated with a highly reflective coating. A pair of lines are scribed on upper and lower surfaces of the block and must be aligned while the target is sighted in the mirrored surface. Other embodiments utilize deep grooves formed in the top of a mirrored or unmirrored club surface.

Abstract: An improved kelly is provided with a drive section which has a uniform cross section defined by three generally flat drive sides alternating with three generally arcuate sides. The three arcuate sides are spaced an equal radii from the central axis of the kelly and the three flat drive sides lie in planes that form an equilateral triangle therebetween.The improved kelly is driven by an improved mating kelly drive bushing which has three rollers positioned so as to evenly transmit torque to the three flat drive sides of the kelly simultaneously.

Abstract: A generally rectangular framework is constructed to hold a plurality of individual advertizing panels. The bottom and two sides of the frame are formed from channel members connected at their corners and designed to snugly but freely receive the plurality of panels. A pair of panel support members which are formed as parallel spaced walls extend between the tops of the side channel members and form the top of the framework. Each wall is connected to the ends of the legs of an angle iron member, the apexes of which are facing and spaced horizontally by approximately the width of the panels. The apexes are spaced vertically by an amount to allow the panels to be slid between them at an angular orientation so that the panels can be lifted in an angled position, pulled between the angle iron members, and rotated to a vertical position to be dropped between the sides of the channel member on the bottom of the framework.

Secured to the lower ends of the end walls and extending across the opening are a plurality of spaced rods to limit the size of objects that may fall through the opening and into the drawer.

Abstract: A method of packaging, and the package so produced, for maintaining living organisms viable for a long period of time. The living organisms, such as bacteria, fungi, algae, etc., are mixed with a carrier, such as peat. The organism-carrier mixture is then disposed in a package, such as a heat-sealable plastic envelope, and a gaseous atmosphere is provided in the package effective to induce and maintain substantial nonvegatative state formation of the organisms. Some organisms will form cysts, others spores, but whatever nonvegetative state is assumed, the organisms will be much less susceptible to heat, cold, starvation, and other adverse environmental factors. Suitable gaseous atmospheres include nitrogen, helium, and argon gases. The package is then sealed to prevent contamination of the atmosphere therein.

Abstract: This invention relates to a door mechanism for a rotary power tong, such as used in well drilling operation. The door is pivoted to one of the bifurcated portions of the tong and a door locking mechanism is used to attach the swinging end of the door to the other bifurcated portion of the tong. At least one contact surface is attached to the door to transmit forces to the door and engage a hook-like member attached to the tong frame. At least one contact member is attached to the frame to transmit forces to the frame and engage a hook-like member attached to the door. Such contact engagements provide for door support in both radial and tangential directions.
