Patent CA-2206931-A1 (CA)
Inventor: SHAW BENJAMIN
IPC: A61M5/00
Filed: 1996-11-26
Abstract: Ambiguity, in readings from an optical bubble detector used with tubing, can be reduced by shaping the tubing into the shape of a prism, so that when different contents of the tubing have differing indices of refraction, there is a clear difference in the exit angle of the light beam leaving the tube. A triangular prism shape is preferred for the compressed tubing. The optical bubble detector features an optics block formed with a V-shaped recess, and a clamp block. The optics block and clamp block cooperatively press or "sandwich" the flexible tubing into the V-shaped recess and deform it into a triangular prismatic cross-section. A generally U-shaped optical interrupter element, containing a photoemitter and a photosensor, fits into the optics block in such a manner that a light beam is directed radially into the triangular tubing section. The clamp block "windows" the transmitted and received light from the optical interrupter, to allow only a thin channel of light to be transmitted; this minimizes optical noise during measurement. When saline is located in the tubing, the light follows a fairly straight path through the optics block and tubing. However, when air is in the tubing, the light is refracted away from the photosensor, resulting in lower intensity readings. By measuring the amount of light received at the photosensor, it can be determined whether air, or saline, is in the tubing.

IPC: E21B7/18
Filed: 1996-08-01
Abstract: A jet assisted drill system which uses a high pressure intensifier (18), positioned in a down hole drill assembly (10). Drill fluid from a drill stem (12) is directed into the drill assembly (10), and in one mode this drill fluid is passed through the pressure intensifier (18) to cause a piston assembly (28) of the intensifier (18) to reciprocate, with the high pressure pistons (34) of the piston assembly (28) delivering high pressure drill fluid to a discharge jet (68) in the drill bit assembly (14). The low pressure fluid which drives the low pressure pistons (32) is discharged into a downstream annular passageway (56) and to the drill bit assembly (14). In a by-pass mode, a selector valve (60) directs drill fluid from an upstream passageway portion (48) directly to a downstream main passageway portion (56) to pass out the drill bit assembly (14). There is a control valve (62) to operate the piston assembly (28) and a trigger valve (64) to direct fluids selectively to the control valve (62).

Title: Device and method for simultaneous bilateral pelvic osteotomies
Inventor: ROOKS ROBERT L
IPC: A61B17/88
Filed: 1998-04-15
Abstract: A method and device facilitates the procedure of a transverse osteotomy of both ilium and a secondary osteotomy through the pelvic symphysis. A plate (40) is utilized which has facility for attachment of eight screws into the animal bone tissue to more securely hold the plate (40) in place. The shape of the plate (40) represents a significant advance and has important characteristics, including (1) only one side of the plate (40) has sharply angled surfaces to accommodate rotated pelvic bone portions, the other side of the plate (40) is smoothly continuous and facilitates a more stable direct insertion of the bone screws to prevent non-even pressure from being applied to the bores (55) provided for insertion of the bone screws; (2) In this configuration, the bores (55) can closely match the shapes of the heads of the bone screws and provide less exposed material at the outside of the plate (40), as well as providing entry of bone screws at right angles to the bone tissue adjacent the sharply angled surfaces; (3) the plate (40) provides the ability for it to be bent and, more than ample material is provided to bend the plate (40) along its axis to provide an even more enhanced ability to insert bone screws at right angles to the extent of the pelvic bone tissue and to avoid an angle which would prevent secure bone attachment of the bone screws and maximum surface area contact and support from the sharply angled surfaces directly onto bone tissue.

Title: Astigmatism measurement apparatus and method
Inventor: LINDOW WILLIAM C
IPC: G01B11/00
Filed: 1996-10-18
Abstract: A computer (30) receives image data from a star-shaped optical target (18) in the object plane and calculates angle-dependent boundary sharpness. The horizontal, x-direction, amplitude derivative and the vertical, y-direction, amplitude derivative are computed over a portion of each star pattern image from a Z panning sequence (83). A microscope slide stage (16), carrying the target (18), is moved vertically from a level just below where the target is in focus to a level just above where the target is in focus. For each small increment of vertical motion, Z panning, an image of the star pattern is captured for analysis (85, 86, 89). Computations are performed on the differentiated images to search for evidence of elongation of the point spread function and variation with stage Z position of the angle of long axis of such an out-of-round point spread function (134). The presence of a distorted point spread function that varies along the optical axis indicates astigmatism (136).

Inventor: WU HENRY T
IPC: F02C7/20
Filed: 1997-01-14
Abstract: A method is described for identifying the primary load path of a particular engine (13). An elastomeric mount (12, 14) may then be made laterally soft in a first (in the disclosed case, the tangential) direction and more rigid in the direction of the primary load path. Efforts can then be directed to dynamically softening the mount (12, 14) in the primary load path. Specific apparatus may include passive fluid devices, active fluid devices, passive nonfluid devices and active non-fluid devices. In the case of a fluid mount, another feature of the invention is to have an auxiliary fill port (66) of the volume compensator (40) in alignment with at least one and, preferably both, of the primary fill port (58) for the mount and the inertia track (38) to facilitate filling.

The extra, or secondary, support (18) core has an outer diameter which is approximately equal to inner diameter of the primary support core (14). The secondary support core (18) is sufficiently long to substantially support the area where the flowable material (16) abuts the primary support core (14). In one embodiment particularly suited for power applications, the elastomeric tube (12) is electrically insulative and the flowable material (16) provides electrical stress control, and another elastomeric tube (20) is provided having a high permittivity. The primary support core (14) may have a varying diameter such that the tubular member (12) has different zones with different expanded diameters. The secondary support core (18) is preferably removed just prior to product application (leaving the larger core intact) so as to increase the product's shelf life.
