Abstract: Coin assorting device having a disc (12) mounted for rotation on a bottom plate (10) to pass below a coin supply tube (19). The rotatable disc includes two pairs of recesses (16) for receiving a coin in each recess, the bottom plate having a discharge opening (20) for coins the diameter of which is less than a predetermined maximum diameter of the coins supplied. The discharge opening (20) extends beneath the mouth of the coin supply tube (19) and is shaped with an upper chamfered edge (24). Opposite sides of the wings (14) of the rotatable disc (12) are shaped in the form of blunt edges having a thickness which substantially corresponds to the thickness of the thinnest occurring coin. Circuitry is associated with the rotatable disc (12) for momentarily reversing the rotational movement of the disc when a coin jamming is sensed.

Abstract: A metal frame structure of the type employing two chords (11) extending in generally the same longitudinal direction and having a plurality of webs (12) extending in zig-zag configuration between the chords (11). The webs (12) are secured to the chords (11) at a plurality of frame joints (13). At each frame joint adjacent webs have opposed flattened end portions (22) which extend in overlapping relation along the inner sides of a respective chord (11) and are secured to the chord by transversely spaced fasteners (14).

Abstract: A pivoting handle type winder or door latch actuating handle (1, 2) and a pivoting stay type of window retaining latch (19, 20) for mounting on a movable frame of an openable door or window, and which is co-operable with a corresponding keeper on or in a surrounding fixed frame in order to latch the movable frame to the fixed frame. The latch comprises a latching element (23) which is movable into latching engagement with the keeper when the movable frame is in a closed position with respect to the surrounding fixed frame, and a locking mechanism is provided to lock the engagement of the latching element with the keeper. An elongate arm (1, 2; 19, 20) is coupled with the latching element, and at least two combinations wheels (9) are mounted on the elongate arm and arranged to control the operation of the locking mechanism so that the latch element can only be released from locking engagement with the keeper when a respective predetermined correct combination is set on each of the combination wheels.

Abstract: An interchangeable lens barrel comprising a lens barrel having a mount which can be attached to a mount of a camera body, focussing lens means rotatably supported on the lens barrel and moving in directions of the optical axis when it rotates, a driving motor, a driving mechanism connected to the driving motor for rotating the focussing lens means, and means on the mount of the lens barrel for receiving a driving signal of the driving motor from the camera body.

Abstract: A surface grinding method in a first embodiment of which a workpiece supported on a surface (56) is rotated about a vertical axis while being translated along ways (46, 47) past a cutting head (22) comprising an abrasive belt (71) driven about a drum (72) to have a working edge (17) skewed with respect to the direction of the ways. In other embodiments the workpiece (100) is fed axially into the belt (106), which may be oscillated transversely to the direction of feed, and the workpiece may be moved, in the direction of the working edge, out of engagement with the belt while the belt and workpiece are in motion.
