Abstract: An infinitely variable angle adjusting device for a handlebar of a motorized vehicle includes a fixing seat, a handlebar stem, a pull handle, an adjusting base, a cover, two sockets, two slides, a compression spring, two urging ball units, a shaft, two press members, and a pull wire. Thus, the adjusting base is movable on the shaft freely, so that the handlebar stem is pivoted relative to the fixing seat, so as to adjust the included angle between the handlebar stem and the fixing seat arbitrarily, so that the inclined angle of the handlebar on the handlebar stem can be adjusted easily and arbitrarily.

Abstract: An eyeglass case comprises a cover including a lengthwise first groove along one side, a lengthwise second groove adjacent and parallel to the first groove, and a lengthwise third groove along the other side; a body including a lengthwise ridge along one side pivotably fitted in the first groove, a lengthwise fourth groove below the ridge, a lengthwise member having a section of V between the ridge and the third groove, and a lengthwise fifth groove along the other side; two side members releasably coupled to the cover and the body, each side member having an interior recess for facilitating of closing the cover onto the body; and two snapping members each having a section of C, a top end clung in the second groove, and a bottom end clung in the third groove for pivotably securing the cover to the body.

Abstract: A rotational control apparatus (10) includes multiple facings (274-276) rotatable with and axially slideable relative to a mount (124) and which sandwich multiple friction plates (252, 253) rotatable with and axially slideable relative to a hub (12). To create turbulent air flow, the friction plates (252, 253) include an undulating outer circumferential edge (258) and a plurality of passages (260) in the interface portion and overlapping the inner peripheries (282) of the facings (274-276). An automotive clutch release type bearing (290) directly abuts between a piston (40) and the friction facing (274) and is encapsulated in the piston cavity (36) and a cavity (277) formed in the friction facing (274), with the friction facing (274) engaging the axial end (34) of the air chamber (24) when the facings (274-276) and the friction plates (252, 253) are disengaged. In the preferred form, the air chamber (24) and the mount (124) are of the same geometry and are machined from identical castings.

Abstract: A nail stapler includes a gun and a magazine for receiving and supplying staple nails to the gun. The gun includes a shell, a solenoid received in the shell, a puncher received in the shell for movement from an original position to a punching position due to attraction by the solenoid, a pin secured to the puncher and inserted through the solenoid, a spring compressed between a portion of the solenoid and a portion of the puncher, and a security device received in the shell for buffering the puncher when the puncher is pushed from the punching position to the original position by the spring. The security device includes an elastic end for contact with the puncher. The nail elastic end of the security device includes a plurality of elastic elements. The puncher defines a cavity with a wall for contact with the elastic elements. The shell includes two halves each including a retainer formed on an internal face. The security device defines a groove for receiving the retainers of the halves of the shell.

Abstract: A nozzle for delivering fluid evenly over a wide swath is disclosed. The nozzle has an elongated tip which has a stepped slot. Air eduction is also provided to reduce drift of the fluid being delivered through the nozzle.
