Abstract: Accelerators and conveyor bodies for a decanter centrifuge are discussed. A decanter centrifuge may have a bowl forming a sedimentation chamber with a cake discharge and a centrate discharge; a screw conveyor within the sedimentation chamber, the screw conveyor having a conveyor body and a flight, the conveyor body defining a feed chamber; and an accelerator within the feed chamber for increasing the angular velocity of a feed mixture prior to entering the sedimentation chamber, the accelerator comprising an impeller with plural vanes, the plural vanes being releasably mounted to the conveyor body and sized to pass through an axial end of the conveyor body.

Abstract: A product is disclosed to assist a vehicle owner and user in properly keeping track of the amount of miles driven in a particular vehicle. The goal of the product is to ensure that regular oil changes will occur approximately every 3,000 miles, which is the usual recommended interval that oil changes occur for most vehicles. The product is a multipage notepad which is preferably one inch tall by one and one-half inches wide, and which can be fastened to an automobile dashboard by means of a mounted Velcro tab, with an accompanying Velcro tab mounted onto the dashboard. The product is designed to provide a user with the ability to perform a quick mathematical calculation in order to determine whether it is presently time to perform an oil change.

Abstract: A pair of half sections forming a hollow chamber with one of the half sections being integrally connected with a rotatable shaft. The shaft includes a passageway through which liquid is inputted to the hollow chamber. One of the half sections is adjustably disposed within the other section thereby forming a variable length valve collar therebetween. A plurality of apertures are formed about the valve collar wherein the effective size of each aperture is varied as the two sections are selectively adjusted with respect to each other to thereby meter the amount of outflow of liquid from the chamber.

Abstract: A golf club includes a club head having two body members and a hosel. Each of the two body members has a planar striking face, and the two faces determine an angle of 90.degree.. Each of the two body members also has a bath surface which is grooved to reduce weight. The hosel joins the body members near the vertex of the 90.degree. angle. A club shaft is inserted into the hosel. Indicia are formed on the upper surfaces of each of the body members which are parallel to a bisector of the 90.degree. degree cycle to aid in aligning the club with the golf ball and the cup into which the ball is to be putted. Tuned resonators are mounted on each of the body members opposite the point on each striking face where the striking faces are tangent to a golf ball touching both faces. The resonators produce audible sounds, which are a function of how the club head strikes a golf ball.

Abstract: A pair of separable sections forming a hollow structure are coupled to a rotatable shaft. Controlled quantities of hydraulic fluid are introduced into the hollow structure through a passageway within the shaft. One of the sections is selectively slidable along the shaft, for release of fluid from within the structure.

Abstract: A game projectile is configured as a polyhedron rather than being spherical or cylindrical in shape. The projectile is independently supported above the low friction base by which it moves across the playing surface. Provision may be made to permit the polyhedron to rotate about its independent support. A further embodiment provides that the location of the point of support of said polyhedral projectile may be varied to assure that the support axis does not pass through the mass center of the projectile. This disclosure teaches the use of impelling instruments having striking surfaces which are configured such that the contact of said striking surfaces with said polyhedron will tend to project the polyhedron across the playing surface on an imprecisely determinable path.

Abstract: A hollow shirred casing stick is provided having the terminal pleats of one end thereof twisted into a funnel-like configuration at least a portion of which is implanted within said hollow stick to form an end closure. An end closure may be formed in a shirred casing stick by twisting the terminal pleats of a shirred casing stick into said stick about a rod member inserted therein. A device is also provided for forming an end closure in a hollow shirred casing stick comprising in combination a red member that is insertable in the end of a hollow shirred casing stick and retractable from within an end closure formed thereabout and a rotatable, twisting member disposed about the rod member for engaging and twisting the terminal pleats of a hollow shirred casing stick about the rod member inserted in the end of a shirred stick.

Abstract: Disclosed herein is a homogeneous, lyophilized particulate product of a substance containing at least one biologically active component and a process for its preparation which involves forming a solution or colloidal suspension of the substance, spraying the solution or colloidal suspension into a moving bath of fluorocarbon refrigerant and lyophilizing the resultant frozen droplets. The porous product has a spherical shape, free-flowing properties, and rapid dissolution times.
