Abstract: A puzzle in which a plurality of object members (52) can be rotatably manipulated in groups, the groups overlapping so that a single object member can be moved from one of the groups to another. Each of the object members has an upper surface (60, 62, 64, 66) with a particular colour or design so that a user may derive enjoyment from arranging the object members into a desired pattern based on their colours or images. In a preferred embodiment, the object members (52) are received in rotatably mounted vane members (27, 29).

Abstract: A detachable cutting blade assembly (10) includes an elongated handle (20) having a rear end and a front end (30) on which a cutting blade (40) can be detachably supported and a blade-locking member (70), in the form of a wall, is secured to the top surface of the front end (30) of the handle. A portion of the wall of the blade-locking member (70) has lateral lips (100) which give the wall a T-shaped cross section and this provides securement for a cutting blade (40). The lips (100) of the blade-locking member (70) are aligned with a hole (36) in the handle (20) and this permits the entire handle (20) to be made with a two-part mold in a relatively inexpensive molding process.

Abstract: The feeding system comprises feed rollers (10, 11, 12, 13, 22, 23, 27, 28) intended for the automatic delivery, advance, and ejection of workpieces. The feed rollers are all driven jointly by a single driving means (6) via various belt or chain drives (5, 31, 39, 41, 42, 44, 45, 47, 48, 50), all have the same peripheral speed and rotate synchronously with an upper cutting head (30) which is driven by the same driving means (6). The feed rollers include delivery rollers (11, 12, 13) disposed before the cutting head and upper (27, 28) and lower (22, 23) ejection rollers disposed after the cutting head. The lower ejection rollers are connected to a vertically adjustable feed table (2). None of the feed rollers need be displaced for adjusting the woodworking machine to different dimensions of workpieces, and the synchronization of the feed rollers and cutting head yields workpieces with uniformly smoothly machined surfaces.

Abstract: A fluorocarbon elastomer having remarkably high tensile strength, high modulus in tension, and excellent retention of tensile strength at elevated temperatures, made from a copolymer of vinylidene fluoride and at least one copolymerizable fluorine-containing monomer blended with a polyfunctional acrylate and exposed to high-energy ionizing radiation to crosslink the copolymer. No thermal curing agent needs to be used unless the elastomer is being molded to form a shaped body such as an O-ring or a gasket. Even then, the preferred amount of thermal curing agent is only about one-fourth the amount used in the prior art for crosslinking such fluorocarbon elastomer copolymers. The fluorocarbon elastomer is especially useful as fuel line tubing and can be so used without a jacket.
