Title: Arrangement comprising a spacer element for an implant, such a spacer element, and a screwdriver for fastening the spacer element
Inventor: BJORN GORAN
IPC: A61C8/00
Filed: 2001-03-22
Abstract: An arrangement including a spacer element operative to support a superstructure and including a first passage and a second passage. The second passage is operative to permit mechanical anchoring of the holder. A first screw is operative to screw the spacer element into an implant. During an initial stage of insertion the first passage is operative to receive the first screw such that a center axis of the first screw is inclined in relation to a direction of screwing of the first screw. During a final stage of insertion the first passage permits the first screw to tilt such that the center axis of the first screw substantially coincides with the direction of screwing. A holder is operative to hold the spacer element. The holder substantially prevents the first screw from leaving the position it has assumed during the final stage of insertion. A second screw is operative to screw the superstructure onto the spacer element.

Title: Fiber optic switch and associated methods
Inventor: PRESLEY HARRY
IPC: G02B26/08
Filed: 2001-09-07
Abstract: The fiber optic switch includes a plurality of optical inputs and a plurality of optical outputs carried by a support. The switch also includes a first plurality of rotatable reflectors each being associated with a respective optical input, and a second plurality of rotatable reflectors each being associated with a respective optical output. Also, a plurality of reflector drivers directs selected pairs of the first and second plurality of rotatable reflectors to define respective paths between the optical inputs and the optical outputs. The free-space propagating optical beam that is transferred between each input and output is formed by a micro lens producing a substantially collimated beam and therefore minimizing optical performance penalties due to the relative path length differences between various routing paths.

IPC: B65B31/00
Filed: 1989-10-17
Abstract: ABSTRACT      A system for pumping fluids and pressurizing gases incorporating an inflatable bladder inside an accumulator or container.  The system uses a liquid for compressing the bladder inside the container and avoids pistons or rotating blades, also provides a pump for corrosive gases and liquids.          The bladder has no connection to the container, and a fluid input line from the bladder has a first non-return valve for connection to a fluid supply.  A fluid output line from the bladder has a second non-return valve and a hydraulic supply system feeds liquid under pressure to the container to compress the bladder within the container and force fluid out through the output line, a drain allows liquid from the container to drain to permit the bladder to fill with fluid, and a timer used in association with a value repeats the steps of feeding liquid to the container and draining liquid from the container.
