Abstract: A jack comprises a frame, a base including an end pivotally mounted to the frame and an engaging portion, an elevating member securely attached to the other end of the base, and a cylinder device including an end pivotally connected to the frame. The cylinder device includes a cylinder and a piston rod having a first end slidably received in the cylinder and a second end beyond the cylinder. The second end of the piston rod is connected to the base to move therewith. When an end of an operative rod is engaged with the engaging portion of the base, the elevating member is quickly elevated when another end of the operative rod is applied with a force. When the operative rod is engaged with the cylinder device, the elevating member is elevated under manual operation on the operative rod.

Abstract: A sensor ring is coaxially mounted on a free end portion of a rotating element for detecting rotations of the rotating element. The free end portion defines an axially extending cylindrical surface and a radially extending stop surface for mounting of the sensor ring. The sensor ring has a cylindrical portion which defines a cylindrical center opening to be press fitted over the axially extending cylindrical surface of the free end portion of the rotating element. The sensor ring also has a flange portion which extends diagonally radially outward from one end periphery of the cylindrical portion such that the flange portion abuts on the stop surface of the free end portion of the rotating element when the sensor ring is completely mounted on the rotating element. The diagonally extending flange portion can avoid a connection curvature between the axial and radial surfaces of the free end portion of the rotating element during the press fitting operation.

When mounting the iron sleeve into the compartment of the chassis, the first pressing member is attached to a side of the chassis and the bolt is extended through the first pressing member and the compartment of the chassis with the bolt head pressing against the first pressing member. The iron sleeve and the push-in member are mounted around the shank of the bolt.

Abstract: Apparatus (10) for packaging products (P) includes a mechanism (84) for accumulating, metering, and creating an array of products (P) in a pack pattern. The array of products (P) in a conveying orientation is transferred to a tray (36), and the tray (36) and the entire pack pattern of products (P) supported thereon are rotated to a second arrangement where the products (P) in the conveying orientation in the tray (36) are perpendicular to the conveying direction. The products (P) are pushed from the trays (36) moving in the conveying direction into cartons (C) moving at the same speed as the trays (36). In the preferred form, the trays (36) are rotatably mounted to carriers (12) moving along a path defined by roller chains (22). A cam follower (48) on a crank arm (46) extending from a spindle (44) rotatably mounting the tray (36) to the carrier (12) travels in a cam track (50) to rotate the tray (36) relative to the carrier (12) between the first and second arrangements.

Abstract: A sunglasses comprising a U-shaped frame having a slot in either end, a groove at the underside having a length substantially the same as frame, a nose pad, a first recess adjacent the nose pad, and a second recess above the first recess; an integrally formed lens having a latched piece in either end and a flexible latched member having a substantially conic shape conformed to the recesses on the top central portion wherein the top edge of the lens, the latched member, and the latched pieces are clung to the groove, the second recess through the first recess, and slots respectively; and a pair of temples. The set of sunglasses is more simplified in components and thus assembly. Further, the stability is enhanced due to the additional securing of the latched member in the second recess.

Abstract: An articulated screwdriver has a handle and a shank secured on the handle. The shank has a ball-end formed at a free end thereof, and an outer thread formed on an outer periphery close to the free end. A joint sleeve has a joint formed at a first end thereof and an opening defined at a second end. The ball-end is pivotally mounted in the opening. A positioning sleeve screwed on the shank has an inner thread engaged with the outer thread. Whereby, when the positioning sleeve is moved forwards to enter the opening, the shank is unable to be pivoted about the joint sleeve and when the positioning sleeve is distant from the opening the joint sleeve is able to pivot relative to the shank.
