Abstract: The present invention teaches a simple and convenient hose end expansion device which slides within the hose end and is then quickly expanded by means of mechanical or hydraulic pressure, thereby stretching the hose end to a larger diameter. The device is then quickly collapsed and removed from the hose end, and a barbed coupling is inserted within the hose before it has sufficient time to return to its original diameter. As the hose returns to its original diameter, the hose coupling becomes secured within the hose end. External hose clamps may be added for increased security and safety.

Abstract: A salad spinner comprising a bowl, a colander adapted to nest within the bowl, and a lid for the bowl and colander. Drive means are associated with the lid for rotating the colander relative to the bowl. The drive means include a handle having one end for manual engagement with the opposite end of the handle being pivotably mounted to the lid. A drive gear is positioned at the opposite end of the handle, and a turret is positioned on the underside of the lid. The turret is rotatably attached to the lid and a pinion gear is provided in driving engagement with the turret. This pinion gear meshes with the drive gear whereby movement of the handle transmits movement to the turret through the pinion gear. Drive tabs are carried by the turret for engaging the colander to impart spinning movement to the colander in response to movement of the handle.

Abstract: A golf ball construction comprising a core and cover, the ball defining an equator forming a first great circle extending over the cover surface. At least two additional great circles extend over the cover surface and intersect the first great circle, the additional great circles being spaced apart equally with respect to each other whereby the ball surface is divided by the combination of the first great circle and the additional great circles into a plurality of discrete symmetrically arranged surface areas. A separate array of spaced-apart dimples is formed on the cover surface within each of the discrete surface areas, each of the arrays covering substantially completely the cover surface in each discrete surface area. Channels are formed exclusively within each area and extend between adjacent ones of the dimples in each area, a channel extending from each dimple to every other dimple adjacent thereto. None of the channels cross any of the great circles.

The maximum lateral dimension of the raised portion, measured parallel to the spherical outer surface, is less than one-half the minimum lateral dimension of the depressed portion. The total effective volume of the dimples comprising the cumulative volume occupied by the depressed portions of all dimples formed in said surface is greater than 0.021 cubic inches.

Abstract: A method for thermally processing polyester pellets by crystallization and polymerization in the solid state which comprises providing a confined processing unit. The pellets are introduced to said unit along with a liquid medium. The combination of pellets and liquid medium is agitated to achieve mixing and the temperature of the agitated mixture is controlled to achieve treating of the polyester pellets in the agitated heating liquid medium at a temperature slightly below the sticking temperature of the polyester. The treatment is continued for a period sufficient to substantially increase the crystallinity and molecular weight of the polyester.

Abstract: A combination key-like device and electrical receptacle for the key-like device wherein the receptacle defines electrical contact surface areas for mating with corresponding contact surface areas defined by the key-like device.

Abstract: A mechanism and method for filling the vacated eyesocket of a deceased person after an eyeball has been donated. A plurality of different sized implant members are positioned within each other, and the larger implant members can be opened to access the smaller implant members. Protrusions are formed on each implant member for engaging the inner surface of the deceased person's eyelids when the implant is positioned within the eyesocket.

Abstract: The drier consists of a plurality of nozzles that direct a small volume of air onto the printed image at as high a velocity as possible without disturbing the wet image. The air so delivered while it must be dry, does not have to be heated to effectively dry the image, however, the drying time can be reduced by increasing the air temperature if desired. The use of high velocity air creates what is known is "skin effect" to dry the ink where the outer surface of the ink is quickly dried.

Abstract: This invention provides an improved apparatus for maintaining tooth rotating wheels, which are used to penetrate the soil either as a cultivating apparatus, a row cleaning apparatus, or as closing apparatus for row planters free of mulch, trash, dirt and/or rocks. By removing the debris from the space between the teeth on the wheel, the wheel can penetrate the soil to a controlled or desired depth as set by the operator. Debris between the wheels can limit the depth of penetration by the formation of a solid or semi-solid mass generally resembling of variable rim diameter. The wheels may be driven by a power mechanism or may be rotated by the penetration in the ground and the forward motion of a propulsion unit.The toothed wheel is kept clean of debris, thereby allowing accurate depth penetration as determined by conditions and requirements.

The second ring member is adopted for insertion into said first ring member with a plurality of complimentary inwardly extending flanges and grooves to form a well known labyrinth seal. There is a slot or channel through the labyrinth or maze connecting the exterior atmosphere to the interior of the seal assembly. The second ring member is adapted to rotate with the shaft and includes an annular recess near the shaft and inwardly toward the housing. There is a plurality of radial holes drilled in the first ring member to be opposite the recess in said second ring member and a plurality of pin members are inserted into the holes in said first ring member and are inserted into the recess of said second ring member. The recess being slightly larger in axial direction than the pin members.

Abstract: A seed furrow closing device for planting units including a plurality of closing wheels, each wheel having a plurality of sharpened teeth on the periphery. The closing wheels canted at an angle to the vertical and press toward the seeds in the furrow.The teeth, controlled by down pressure mechanism, penetrate the soil to till compacted soil and firm loose soil to improve germination and emergence. The sharpened teeth interact with the soil to remove residue from the teeth as the teeth emerge. The penetration of the teeth helps break up clods and also stabilizes the rear of the planting unit.A trailing press wheel over the furrow may provide intermittent compacting of the soil loosened by the closing wheels over the center of the furrow.This loosening and compaction by the sharpened toothed wheels improves the germination and emergence of the seeds in the furrow.
