Title: Method and apparatus for measuring continuous blood flow at low power
Inventor: BOWMAN HARRY F
IPC: G01F1/68
Filed: 1995-03-14
Abstract: A technique for determining blood flow in a living body by changing the thermal energy level by a predetermined amount at a site in a blood flow path and detecting temperatures at locations upstream and downstream of the site. The temperature difference at such locations determined and the blood flow is calculated as a function of the change in energy level and of the temperature differences measured prior to and following the change in energy level.

Title: Seal arrangement for batch coil annealing furnace
Inventor: HEMSATH KLAUS H
IPC: F27D99/00
Filed: 1995-04-26
Abstract: An improved seal arrangement is disclosed for use in batch coil annealing furnaces. The furnace has extending from its base a pair of cylindrical upright supports having exposed membrane  engaging  seal  edges  and  between  which  an underpressure chamber is formed.   The inner cover which removably  rests  on the base,  has  an annular top  plate extending radially outwardly from its sidewall adjacent the cover's bottom end.  Extending vertically downwardly from the top plate are concentric inner and outer clamp mechanisms which clamp flat annular elastomer seal therebetween.   An overpressure chamber is formed between the seal and the top plate and when the inner cover is seated on the base, an underpressure chamber is formed between the seal and the upright supports.   A positive pressure is applied to the overpressure  chamber  and  a  vacuum  is  drawn  in  the underpressure chamber to insure that the seal is forced into sealing contact with the upright engaging surfaces,  thus assuring a positive seal of the inner cover with the furnace base.

Title: Structural protection assemblies
Inventor: HUDAK DAVID BRUCE NESSETH
IPC: E02D29/02
Filed: 1995-05-10
Abstract: The assembly is comprised of a flexible enclosure, filled with a suitable pressure wave attenuating medium material having a lower acoustic impedance than water so as to reflect shock wave energy.  This basic configuration can be mounted in the form of panels and attached to the  structure it  is intended to protect, in which case it will form a flexible barrier of low acoustic impedance and be orientated between the structure and the water or ground in contact with the structure.  The pressure absorbing and attenuating medium that will reflect shock waves may be a gas,  compressed air,  a closed cell foam or expanded foam.  The flexible enclosure may be made of rubber or plastic or elastomer.  For certain types of foaming agents, the outer skin will harden into a suitable enclosure so that no discrete shell or enclosure is necessary.
Patent CA-2153415-A1 (CA)
Title: Front end apparatus and method
Inventor: CLARK GREG S
IPC: G01N11/00
Filed: 1994-06-20
Abstract: Air is supplied from an air supply through a disposable pipette tip (11). With no obstructions in the path from the supply through the tip, air will flow freely and little back pressure will be measured by a pressure transducer (12) located upstream from the tip in an air supply circuit. The tip is lowered toward the surface (16) of the liquid by a robotic arm (20). As the lip contacts the surface, the liquid blocks airflow and the pressure sensed by the transducer increases. This increase signals that the pipette tip has located the liquid level. The tip is lowered beneath the liquid level and a vacuum source is then coupled to the air supply circuit The liquid is drawn onto the tip. The transducer measures a negative pressure. The measured pressure depends on air flow rate, liquid viscosity and a number of other secondary factors. If flow rate and these other factors are known, viscosity and change in viscosity can be measured. A clot or gel in the liquid u the tip produces a larger increase in the partial vacuum and hence the clot or gel is detected.

Title: Optoelectronic Devices Utilizing Multiple Quantum Well Pin Structures and a Process for Fabricating the Same
Inventor: CUNNINGHAM JOHN E
IPC: G02F1/017
Filed: 1995-08-17
Abstract: Optoelectronic devices such as photodetectors, modulators and lasers with improved optical properties are provided with an atomically smooth transition between the buried conductive layer and quantum-well-diode-containing intrinsic region of a p-i-n structure. The buried conductive layer is grown on an underlying substrate utilizing a surfactant-assisted growth technique. The dopant and dopant concentration are selected, as a function of the thickness of the conductive layer to be formed, so that a surface impurity concentration of from 0.1 to 1 monolayer of dopant atoms is provided. The presence of the impurities promotes atomic ordering at the interface between the conductive layer and the intrinsic region, and subsequently results in sharp barriers between the alternating layers comprising the quantum-well-diodes of the intrinsic layer.

Reciprocating movement be-tween the cover member relative to the pump member urges fluid from within the cavity through one of the first and second valves on a first stroke and urges fluid into the cavity through the other of the first and second valves on an opposite stroke.
Patent CA-2160032-A1 (CA)
Inventor: ESTABROOK BRIAN K
IPC: A61B17/32
Filed: 1994-03-31
Abstract: The ultrasonic instrument includes a shaft (12) having an integral sheath (20) of PTFE encompassing the shaft and attached solely to the shaft. At the proximal end of the shaft, wrench flats (24, 26) arc exposed through openings in the sheath and grooves cooperate with complementary ribs (32, 34) on the sheath to prevent relative longitudinal and rotational displacement of the sheath and shaft. The sheath is in contact with the shaft at the nodes along the shaft. To manufacture the instrument, the sheath is initially formed to a diameter equal to or less than the diameter of the shaft and then mechanically expanded. Subsequently, the sheath is heat-shrunk about the shaft, and rolled continuously along the shaft, except at regions corresponding to the nodes along the shaft, to expand the sheath to a larger diameter to space the sheath from the shaft except at the nodes of the shaft.

Title: Animal ear tag mounting mechanism
Inventor: HICKS DONALD D
IPC: A01K11/00
Filed: 1995-12-28
Abstract: A snug fitting two-piece tagging system which employs a lowgrade spring function therein. The present invention provides a piercing stud coupled to a domed shaped member. The compressible domed shaped member may have an outer surface which is domed away from the piercing stud and is concavely rounded on the inner surface from which the stud emanates. Further, the compressible domed shaped piercing stud may be formed from a flexible material. In this configuration, the compressible domed shape piercing stud functions as a low-grade spring which may be slightly compressed upon installation. That is, the piercing stud base may be snug against the tagged material around the contacting perimeter, leaving no gap to snag a foreign object. Another embodiment of the present invention allows for interruption of contact around the contacting perimeter of the compressible domed shaped member to prevent the entrapment of moisture or the like in and around the compressible domed shaped member. This embodiment may prevent necrosis under the tag element while providing the attendant advantages of the spring action discussed above.

IPC: H01L21/22
Filed: 1996-01-17
Abstract: InGaAs photodiodes are produced on an epitaxial InP wafer having an InP substrate, epitaxially-grown layers and an InGaAs light-sensing layer. An insulating-protecting film of Si x N y or of SiO x is deposited thereon with openings selectively in the epitaxial wafer. Compound semiconductor undercoat layers of a compound semiconductor are then grown having a band gap which is narrower than InP on the InP window layers at the openings by utilizing the insulating-protecting film as a mask. A p-type impurity is diffused from a solid source or from a gas source through the undercoat layers and the epitaxial InP layer into the InGaAs light-sensing layer.  P-electrodes are formed on the undercoat layers and the undercoat layers are then etched by utilizing the p-electrodes as a mask. Alternatively, the undercoat layers may be shaped by selective etching in the form of p-electrodes and forming the p-electrodes on the undercoat layers.
