Abstract: A device for rehabilitation of the upper limb includes a frame and an exoskeleton mounted on the frame. The exoskeleton has a first joint coupled to the frame, a first L-shaped connector connecting the first joint to a second joint, a second L-shaped connector connecting the second joint to a third joint, and an attaching member attaching an upper limb of a human subject to the exoskeleton. The first joint is situated above a shoulder of the human subject and has a first axis of rotation substantially coinciding with the horizontal abduction/adduction rotation axis of the shoulder. The second joint is situated behind the shoulder and has a second axis of rotation coinciding with the abduction/adduction rotation axis of the shoulder. The third joint is situated at the side of the shoulder and has a third axis of rotation substantially coinciding with the flexion/extension rotation axis of the shoulder.

Abstract: A spray gun and a detachable liquid reservoir releasably attached to the spray gun by engagement of mateable, non-threaded formations provided on the spray gun and the reservoir. The spray gun has an integral connector boss with a socket for reception of a connector tube of the reservoir. The boss has an external flange at the distal end and the reservoir has hook members separate from the connector tube. The hook members are co-operable with the flange when the connector tube is received in the socket to secure releasably the reservoir to the spray gun. In another arrangement, the connector tube is an interference friction-fit in the socket to secure releasably the reservoir to the spray gun. In yet another arrangement, the connector tube has bayonet lugs co-operable with bayonet grooves in the wall of the socket when the connector tube is received in the socket to secure releasably the reservoir to the spray gun.

Abstract: The invention disclosed is a printing system particularly useful for printing languages having large number of characters such as Chinese. The printing system in one aspect comprises a packet of coaxially disposed printing elements, each having a generally flat edge, an axis of rotation proximate that edge, and at least one series of character faces disposed circumferentially relative to the axis of rotation. The printing elements are generally mutually aligned so that their flat edges are disposed adjacent to a print receiving means such as a platen and are axially translatable so that any selected printing element can be placed in a pre-print position. Each printing element is rotatable so that a selected character face on the printing element in pre-print position can be juxtaposed into a print position relative to the print receiving means for printing of the character.
