Title: Polarization rotator with frequency shifting phase conjugate mirror and simplified interferometric output coupler
Inventor: ROCKWELL DAVID A
IPC: G02B5/30
Filed: 1994-06-16
Granted: 1999-12-14
Abstract: An interferometer that is used with a frequency shifting phase conjugate mirror (PCM) (12), to produce a 90° polarization rotation, employs only two adjustable elements:  a specially shaped prism (16), and a beam deflector that is preferably a porro prism (40). The primary prism is shaped and oriented so that a linearally polarized input beam (4) is divided into ordinary (o) and extraordinary (e) subbeams (24,26). One of the subbeams (26) is refracted out of the prism along a controlled length path, and then returned back into the prism by the deflector. The second subbeam (24) is retained within the prism by total internal reflection, and directed onto a exit path (38) that coincides with the path of the first subbeam after its reentry into the prism. The recombined output beam (10) is directed into the PCM, from which it is reflected back into the prism for a reverse pass. The difference in path lengths between the o and a subbeams is selected to produce a net 90° polarization rotation after both passes.

Abstract: A pilot stage for pressure control valves comprises an axially displaceable valve piston (110) which bounds a valve chamber (141) axially on one side and includes a valve seat (140) for a closure cone (104) therein. Valve piston (110) has an actuating surface in a pressure chamber (164) that is substantially larger than the free cross-section of the valve seat (140). By pressurization of this pressure chamber (164), a large hydrostatic force is exerted on the valve piston (110) which opposes the closing force of the pressure-setting spring (106). A housing stop (130) fixes a first axial end position of the valve piston (110) in the direction of this hydrostatic force. The pilot control stage has improved properties both in manually adjustable pressure control valves and in proportional pressure control valves.

Title: Dental matrix strip
Inventor: LOCOCO MICHAEL
IPC: A61C5/12
Filed: 1995-12-22
Granted: 2007-08-07
Abstract: A dental matrix of the type of a flexible strip, preferably made from a thin , strong, flexible material such as Mylar.TM.. Instead of the usual rectangula r band, the strip tapers toward one end to provide a variety of sections having different width so that the overlap of a cavity, usually in the interproximal surface of a tooth, can be accurately made by simply sliding the strip to a desired position. As a result, there is an improved strength with which the strip envelopes th e immediate vicinity of the filled cavity thus preventing undesired escape of the filling material towards the gum or towards the incisive part of the tooth. Two embodiments are disclosed.

Abstract: A method for retrieving video data which has been striped across a plurality of disks using a coarse-grained striping technique. Specifically, and in accordance with an illustrative embodiment of the present invention, the method comprises scheduling the retrieval of a video in response to an incoming request and based on the availability of bandwidth on the disks, and then rescheduling the retrieval of that video to occur at an earlier time, the rescheduling based on a change (i.e., an increase) in the availability of bandwidth on the disks which results from the retrieval of another video being completed. The scheduling and rescheduling may, for example, comprise assigning a disk to the video, where the method further comprises incrementing the disk assigned to the video as each round occurs and beginning the retrieval of the given video when the disk assigned to it is the disk on which the data for the given video begins.
