Abstract: A rotary cutting tool having a plurality of removable cutting inserts is provided. The rotary cutting tool comprises a rotary tool body for rotation about a central shaft. A plurality of slots extend radially inwardly from the outer peripheral edge of the tool body for supplying a plurality of cutting inserts. Each of the cutting inserts has a geometrical configuration. The geometrical configuration is for engagement with an annular rib on an attachment ring. A pair of attachment rings entrap the tool body and cutting inserts therebetween. The ribs on the attachment rings contact only the insert by way of an interference fit with the geometrical configuration on the tool insert and the geometry of the groove in the tool body thereby locking the tool insert with respect to the tool body.

Abstract: An enclosed track conveyor chain assembly and method of construction includes a plurality of guide link assemblies and load link assemblies connected to form a conveyor chain assembly. Each load link assembly includes a pair of side walls and forward and rearward ends defining an opening. A pair of wheel assemblies supports the load link on the horizontal surfaces of the track. A guide link member is inserted into the opening of adjacent load links. Distal ends of the guide links are connected via a fastener to thereby connect adjacent load link members to form the enclosed track chain. Each guide link member includes a plurality of flat areas on the distal ends of the arms to provide a connecting surface. A fastener is inserted through openings in the distal ends to secure the guide link members together. Preferably, the connection between guide link members is pivotal to allow pivoting action of the guide link.

Abstract: A cam for a compound archery bow has an adjustable draw cam and a draw stop arm, each releasably and adjustably carried by the cam to permit rapid adjustment of the draw length and let-off characteristics of the cam without having to completely disassemble the bow and without having to replace either of the adjustable draw cam or draw stop arm with different components. Therefore, a plurality of draw lengths as well as let-offs may be achieved by the consumer without having to completely disassemble the bow or purchase a plurality of different, specialized parts. Advantageously, the number of different parts which need to be produced to provide a wide range of draw lengths and let-offs is drastically reduced to greatly facilitate the economical manufacture of cams for archery bows.

Abstract: An apparatus for kneading or mixing materials. The apparatus including a housing having first and second separable housing sections. A cavity in each housing section, the cavities cooperating together to form a mixing chamber when the housing is closed. First and second liners are releasably secured by liner retainers to the respective first and second housing sections. A plurality of kneader pins are secured to the liner sections and cooperate with a kneader screw disposed in the mixing chamber to knead or mix various materials.
