Inventor: BRYAN ROBERT N
IPC: A61B34/20
Filed: 1989-11-21
Granted: 1999-04-06
Abstract: A computerized system for viewing of internal anatomical regions of a patient based on previously acquired image data of the patient.   The anatomical regions are viewed in direct relationship to a moving probe which can be hand-held.   The location of the probe relative to the patient is reported to computer.  The computer then uses the previously acquired image data to generate a desired view of the patient's anatomy in relationship to the position or orientation of the probe.  An operator is able to visualize normally invisible anatomical features  before  commencing,  and  during,  procedure.    The correspondence between positions of the patient's anatomy is to locations on the stored data images is determined through an initialization procedure which can be repeated or refined between viewing  operations.    The  system  may  be  employed  during diagnostic, therapeutic, or surgical procedures.

Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for collecting fish eggs comprises a conveyor for transporting fish with the upper half of each fish inclined obliquely upward, a pair of upper and lower conveyor belts for holding the tail of each fish therebetween during transport, a pair of upper and lower conveyor belts for holding the trunk lower half portion of each fish therebetween during transport, trunk support portions and fish back restraining frames arranged alternately on the lower trunk holding belt, a head cutter disposed close to the terminal end of the conveyor, a member for pressing the abdomen of each fish after its head has been cut off, and an operating mechanism for the pressing member.         During transport on the conveyor, the eggs in the abdominal cavity of each fish move toward the tail of the fish under gravity, and the head is thereafter cut off by the cutter.  During the subsequent transport operation, the fish has its abdomen pressed by the member, is bent rearward about the portion thereof held by the trunk holding belts and is prevented from being further bent by the restraining frame in bearing contact with the back of the fish.  The member therefore fully exerts its pressure on the fish to completely squeeze out the eggs from the head cut-off face for collection.

Title: Optical waveguide amplifier source gyroscope
Inventor: FESLER KENNETH A
IPC: G01C19/72
Filed: 1991-07-31
Granted: 2002-04-30
Abstract: An improved Sagnac interferometer includes a broadband light source (100) that comprises a fluorescent optical medium which is pumped by light from a pump source with a sufficient intensity to cause the fluorescent optical medium to generate temporally incoherent light by superfluorescence. In the preferred embodiment, the superfluorescent optical medium comprises an optical fiber (130) which is backward pumped. The light signal input into the sensing loop (142) of the interferometer is amplified by a modulator, output from the interferometer loop (142) and amplified by the optical gain of the superfluorescent fiber which acts as a light source (100) and as an amplifier. In order to avoid gain modulation in the superfluorescent fiber (130), the modulation frequency is selected so that the modulation gain depth is substantially reduced.

Title: Rf repeater arrangement with improved frequency reuse for wireless telephones
Inventor: BEASLEY ANDREW S
IPC: H04B1/46
Filed: 1992-01-03
Granted: 1997-03-18
Abstract: An RF repeater arrangement for use in a wireless telephone system has a number of handset interface parts, each provided with a transmit section for transmitting a signal to a wireless telephone handset, a receive section for receiving an off-air signal from the wireless handset and an energy detector fordetecting the energy level of the received off-air signal and providing a control signal corresponding to such energy level. The control signal is employed for inhibiting the transmit section when the energy level of the received off-air signal is below a predetermined value. Thus, each handset interface part can determine when a channel is occupied and avoid transmission on that channel, so that only the geographic area around the occupied handset is subject to interference from the occupied channel.

Title: Edible fats
Inventor: VAN MEETEREN JOHANNA ANTONIA
IPC: A23D7/02
Filed: 1992-02-03
Granted: 2001-12-11
Abstract: The processability of a margarine or other edible spread fat blends and the properties of the resulting products are to a large extent determined by the crystallisation behaviour of the fat blend. Problems of delayed crystallisation are known in the art of margarine or other spread manufacture, in particular, it is common knowledge in margarine blend formulation that interesterification of fats quite often results in slower crystallising fat blends and often fat blends which are impractically or inconveniently slow to crystallise. We have now determined that the crystallisation of margarine fats from a supercooled melt can be accelerated by the use of a triglyceride having a trans fatty acid at the 2-position, preferably a 1,3-saturated-2-trans-unsaturated (FTF) tempering accelerator. These include, in particular the HTH TAGS where H is stearic or palmitic, and especially PEP.

Title: Utility power pole system
Inventor: MCCOMBS P ROGER
IPC: E04H12/02
Filed: 1992-06-16
Granted: 1996-09-17
Abstract: A utility power pole system comprises a pultruded hollow primary pole having an external hexagonal cross section and a number of longitudinal exterior grooves along its length. The hollow primary pole also has an internal hexagonal cross section rotated 30° relative to the external hexagonal cross section . One or more pultruded hollow liners are provided which are also hexagonal in cross section and which may be internally or externally concentric with the primary pole.          These liners vary in length to achieve an effective structural taper to the power pole system. The insertion of a tapered liner in the lower portion of the utility pole results in a utility pole having the effective load bearing capability of a tapered utility pole. By using a plurality of overlapping liners of varying lengths, an effective taper can be provided to the utility pole. The longitudinal grooves in the outer surface of the primary pole provide a means for climbing for a utility lineman and a means for attaching accessory attach-ment devices such as cross arms, stiffening members, conductor supports and for interconnection with other structural elements in a more extensive system. The rounded edges of each longitudinal groove are directed inwardly so as to retain devices in the groove which conform to the cross section of the groove. Cross arms attached to the utility pole may also employ similar longitudinal grooves to facilitate inter-connection with existing utility hardware or other components.

IPC: E21B47/01
Filed: 1992-06-24
Granted: 2002-08-13
Abstract: A system for maintaining a downhole instrumentation package in a roll stabilised orientation with respect to a drill string comprises an instrument carrier which is mounted within a drill collar for rotation about the longitudinal axis of the collar. An impeller is mounted on the instrument carrier so as to rotate the carrier relatively to the drill collar as a result of the flow of drilling fluid along the drill collar during drilling. The torque transmitted to the instrument carrier is controlled, in response to signals from sensors in the carrier which respond to the rotational orientation of the carrier, and input signals indicating the required roll angle of the carrier, so as to rotate the carrier in the opposite direction to the drill collar and at the same speed, so as to maintain the carrier non-rotating in space and hence roll stabilised.  The torque may be controlled by controlling a variable coupling between the impeller and the carrier and/or by controlling a brake between the carrier and the drill collar.
