A simultaneous-rotating hinge has a body, a first leaf and a second leaf. The body has a gear assembly. The gear assembly is mounted in the body and comprises multiple gears that engage each other. The first leaf is mounted rotatably on the body and connects to one of the gears in the gear assembly. The second leaf is mounted rotatably on the body and connects to another gear in the gear assembly. Interaction of the gears causes the first leaf and the second leaf to pivot simultaneously toward or away from each other.

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

An improved golf ball driver has a first weight positioned within the clubhead of the driver, and a first means for adjusting the first weight in a generally vertical direction within the clubhead, that is, from top to bottom thereof. The improved driver also has a second weight positioned within the clubhead, and a second means for adjusting the second weight in a generally horizontal direction within the clubhead, that is from the heel to the toe thereof. Adjusting the weights allows a golfer to eliminate natural swing problems and / or to make a desired change in the flight pattern of a golf ball when it is struck by the driver.

In one aspect the invention provides an optical circuit enclosure enclosing at least one optical circuit or optical circuit component; the enclosure comprises: a tray type container containing at least one optical circuit or optical circuit component; a tray type closure member closing the container; the closure member containing at least one further optical circuit component on an external side thereof for optically connecting the enclosed component to an external optical circuit; and sealing means providing a moisture resistant seal between the container and the closure member.

The self-ligating bracket for use in orthodontics comprisesa base; an occlusal wall and a gingival wall extending from the base and having at least one ligature wing; a slot separating the occlusal wall and the gingival wall; a slide retained in a guide provided in the occlusal and / or gingival wall and arranged for being displaced between a closed position, in which the slide bridges the slot, and an open position in which the slot is open in the labial direction; means capable of retaining the slide in both its closed and open position; at least one recess in which a spring is seated and which is arranged in the gingival or occlusal wall of the bracket and is provided with an opening that faces the slide and from which a spring projects; a first stop on the slide which abuts against the at least one spring in the open position of the slide; a projection is which provided on the slide and which is so arranged that during displacement of the slide to its closed position it will abut against the spring before it reaches its closed position; space on both sides of the projection which accommodates the spring that projects from the recess which expands toward its opening facing the slide so that the spring can bent in the two directions of displacement of the slide; a second stop that abuts the slide in its closed position, once its projection has overcome the at least one spring.
