Patent CA-1289788-C (CA)
Title: Operating microscope providing an image of an obscured object
Inventor: FANTONE STEPHEN D
IPC: G02B21/22
Filed: 1987-12-16
Granted: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE      An  improved  microscope  features  real  time generation of combined visible and converted images. The converted image is of an object which is obscured by a layer of material which is opaque to visible light, but which is substantially transparent to non-visible pentrating  radiation.    In  an  operating  microscope application, the invisible penetrating radiation may be radiation of wavelength greater than 620 nm, to which blood is transparent.  The converted visible image made using  the  reflected  pentrating  radiation  will  show tissues underlying a layer of blood,  which otherwise would  obscure  the  tissues  from  being  viewed  by  a surgeon.  The converted and visible images are combined to generate a combined image which is more useful than would  be  the  reflected  penetrating  radiation  image alone.  Image enhancement techniques may be employed to enhance the converted image.

Title: Switching circuit for a refrigerator control
Inventor: JANKE DONALD E
IPC: F25D17/04
Filed: 1987-12-17
Granted: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE     An AC voltage motor switching circuit for a refrigerator control has a temperature responsive portion connected to provide gate current to an SCR which is connected with a reverse-poled diode to form a parallel combination, which together are in series with the AC motor and a charging capacitor.  When the SCR is gated on, the SCR conducts positive half-waves of the voltage source and the diode conducts negative half-waves causing the capacitor to become an AC reactance device and, thus, the motor to be energized.          When the SCR is gated off, only the negative half-waves of the AC signal are capable of being transmitted through the diode which fully charges the capacitor and prevents current flow through the windings of the motor to deenergize the motor.

Title: Method and apparatus for reducing blockage in body channels
Inventor: MURPHY-CHUTORIAN DOUGLAS R
IPC: A61B17/22
Filed: 1987-12-24
Granted: 1993-03-09
Abstract: ABSTRACT OF DISCLOSURE   An instrument for removing an obstruction in an internal body channel comprises an elongated catheter body adapted for insertion into a body channel having a first lumen throughout its length. An elongated guide and laser transmission conduit extends through the lumen of said catheter body and is  movable therein so that its distal end  can  be  extendable  beyond  the  distal  end  of  the catheter body. The proximal end of the movable conduit is connected  to  a  controlled  source  of  laser  energy.  A treatment element  is provided at the distal end of the catheter body for further reducing the channel obstruction following preliminary penetration thereof by the movable laser transmission conduit. The treatment element may be a fixed laser transmission conduit which terminates at the end of the catheter body or a dilatation balloon near its distal end. In method steps utilizing the instrument, the movable conduit is positioned near a channel obstruction to enlarge a passage through and then serves to guide the catheter body into position so as to further enlarge or remove the obstruction using its treatment element.

Granted: 1999-06-29
Abstract: Genetically engineered host cells containing new expression cassettes are provided which are able to carry out biochemical oxidations of steroids. In particular the oxidation is carried out with cells into which DNA has been introduced which encodes protein involved in the biological pathway of cholesterol to hydrocortisone. Suited host cells comprise species of Bacillus, Saccharomyces or Kluyveromyces.      The new host cells are suited for microbiological oxidations of cholesterol, pregnenolone, progesterone, 17.alpha.-hydroxy-progesterone, and cortexolone, which are intermediates in said biological pathway. The new expression cassettes are also useful in the ultimate production of a multigenic system for a one-step conversion of cholesterol into hydrocortisone.

Title: Shoe with naturally contoured sole
Inventor: ELLIS FRAMPTON E III
IPC: A43B5/00
Filed: 1989-07-14
Granted: 2001-05-22
Abstract: A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole that conforms to the natural shape of the foot, particularly the sides, and that has a constant thickness in frontal plane cross sections. The thickness of the shoe sole side contour equals and therefore varies exactly as the thickness of the load-bearing sole portion varies due to heel lift, for example. Thus, the outer contour of the edge portion of the sole has at least a portion which lies along a theoretically ideal stability plane for providing natural stability and efficient motion of the shoe and foot particularly in an inverted and everted mode. In a more conventional embodiment, wherein the side contours of the shoe sole are formed by variations in the bottom surface alone, the edge portion of the sole is contoured and defined by an arc of a circle having a radius equal to the thickness of the sole portion of the sole and its center at a point lying on the plane of the upper surface of the sole thickness.
