Patent CA-2120494-A1 (CA)
Title: Apparatus for reducing can spacing and speed
Inventor: WILLIAMS ROBERT
IPC: B65G47/84
Filed: 1992-10-08
Abstract: A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain. Linear speed of the holding devices while moving through the transfer region exceeds chain speed, and in this region the holding devices are spaced apart by a distance that exceeds pin spacing. By the time the holding devices reach the pickup region they are arranged in two rows, are spaced apart and are moving at a speed such that they essentially track the moving pins while the latter are being loaded.

Title: Wide angle, deep field, close focusing optical system
Inventor: FRAZIER JAMES A
IPC: G02B23/02
Filed: 1995-06-26
Abstract: An optical system having the features of a wide angle lens, a deep field lens and a close focusing lens is comprised of an objective lens, a field lens and a relay lens aligned on an optical axis in that sequence for the objective lens to form an intermediate image at or near the field lens and for the field lens and relay lens to transmit that same image to a smaller final image at the plane of the film of a film camera or charge coupled device of a video camera. The objective lens preferably has a fixed focal length and a wide open aperture for forming the intermediate image of a larger size than is otherwise normal for an objective lens of that focal length. Preferably, the relay lens has the iris and focusing mechanism whereby the objective lens and field lens are not required to be used for aperture control and focusing. The optical system provides an extended optical axis for accommodating lighting of a near object being photographed. In modifications of the basic optical system, the optical axis is turned 90° one or more times and rotatable joints are provided in the lens barrel for versatile positioning of the objective lens relative to the camera with appropriate prisms for inverting and reversing the orientation of the final image at the film or CCD detector plane.

Patent CA-2156372-A1 (CA)
Inventor: HANCOCK WILLIAM JOHN
IPC: A47C1/032
Filed: 1995-08-17
Abstract: A chair mechanism (1) has a seat support (11) and a backrest support (50) which can pivot about pins on a fixed support (2). They are interconnected so that their tilting is synchronised.  A lock (30) locks the seat support (11) at a certain tilt position with respect to the fixed support (2) and therefore in turn locks the backrest support.  The lock (30) has lock members (36, 37) with ridges or teeth which interengage to provide positive mechanical locking . The teeth are configured so that tilt bias which is provided by a bias unit (15) urges the teeth into tighter locking engagement once they are engaged. Therefore, accidental release of the actuator does not cause the lock to become released and therefore jerking actions of parts of the chair are avoided.  For releasing of the lock, it is necessary for the user to urge parts of the chair against the tilt bias, thereby causing release surfaces on the teeth to slide with respect to each other to urge the locking member (37) away from the locking member (36).  The slopes of the surfaces on the teeth are important as they provide for tighter mechanical engagement under the tilt bias and for disengagement when the user urges a chair part against the tilt bias.
