Title: Surgical device for volumetric localization, biopsy and surgical procedures
Inventor: MOSBY RICHARD A
IPC: A61B10/00
Filed: 1992-01-20
Abstract: SURGICAL DEVICE FOR VOLUMETRIC LOCALIZATION, BIOPSY AND SURGICAL PROCEDURES     ABSTRACT OF THE DISCLOSURE     A surgical device for volumetric localization, biopsy and surgical procedures consists of a tubular shaft containing an array of filaments which are preformed and preloaded as springs.           The filaments when deployed by extension from the tubular shaft, after insertion through or adjacent to a tumor or other tissue mass, form a predetermined, i.e., substantially closed loop, con-figuration outlining, encasing and excluding a known volume of tissue, i.e., tumor or other tissue mass, from the human body for the purpose of localization, biopsy or surgical removal,  The filament array configuration, when outlining, enclosing and ex-cluding the tumor or other tissue mass, limits tissue exposure to conventional and nonconventional forms of surgery to that within the encircling filaments.
Patent CA-2059848-A1 (CA)
Title: Liquid crystal display and reflective diffuser therefor
Inventor: ELDERFIELD DAVID V
IPC: H04M1/22
Filed: 1992-01-22
Abstract: ABSTRACT A diffuser for backlighting a display panel consists of a shell having a flat surface for positioning against the backside of the panel.  A reflection cavity extending into the shell from the flat surface has highly reflective walls one of which opposite the mouth of the cavity defines a ramp.  An illumination cavity extending into the shell intercepts the reflection cavity at an aperture near the foot of the ramp. When light propagates from the illumination cavity into the reflection cavity, the walls of the latter cavity distribute that light by reflection and the ramp redirects that light to the mouth of the reflection cavity from which the light propagates to the display panel as a uniform diffuse emanation.

Title: Bleed alleviation in ink-jet inks
Inventor: MOFFATT JOHN R
IPC: C09D11/02
Filed: 1992-02-04
Abstract: Color bleed (the invasion of one color into another on the surface of the print medium) using ink-jet inks is al-leviated by employing zwitterionic surfactants (ph-sensi-tive or pH-insensitive) or ionic or non-ionic amphiphiles.      The inks of the invention comprise a vehicle and a dye.      The vehicle typically comprises a low viscosity, high boil-ing point solvent, one or two amphiphiles at concentrations above their critical micelle concentration (cmc), while the dye typically comprises any of the dyes commonly employed in ink-jet printing. The amount of surfactant/amphiphile is described in terms of its critical micelle concentration (cmc), which is a unique value for each amphiphile. Above the cmc, micelles form, which attract the dye molecule and thus control the color bleed. Below the cmc, there is no micelle formation, and thus no control of the color bleed.

Title: Tow vehicle alignment method and apparatus
Inventor: PARENT RICHARD A
IPC: B60R1/00
Filed: 1991-01-18
Abstract: A method and apparatus for monitoring towed vehicles, such as trailers and the like, which are not visible in a rear view mirror of a tow vehicle. The method consists of, firstly, attaching markers to a towed vehicle such that the markers are visible on each side of a towing vehicle to which the towed vehicle is coupled. Secondly, projections are attached to each side of the towing ve-hicle. The projections are positioned on each side of the towing vehicle so that the projections are in respective linear alignment with the markers when viewed from respect-ive side mounted rear view mirrors of the towing vehicle.  When the markers cease to be in linear alignment with the projections during driving, the driver of the towing vehicle is alerted that there has been an alteration in the positioning of the towed vehicle relative to the towing vehicle, thereby indicating a problem requiring a stoppage of the vehicles.

Title: Sheet metal motor mount
Inventor: GREENFIELD JOHN B
IPC: F04D25/08
Filed: 1992-09-21
Abstract: ABSTRACT OF THE DISCLOSURE The  drive  motor  of  a  centrifugal  blower  is coaxially supported within the blower housing using a circumferentially spaced  series  of  four  specially  designed  sheet  metal  motor mounts.    The  mounts  have  generally  planar  bodies  extending radially across an inlet air intake annulus defined between the blower motor housing and a cross-sectionally rounded circular edge portion formed through a blower housing inlet side wall and bordering the blower inlet opening.  The plane of each mount body is positioned generally parallel to the motor axis so that mount blockage  and  disruption  of  blower  inlet  air  is  minimized.          Transverse inner end portions of the mounts are rigidly secured to the  outer side of the drive motor by sheet metal screws.          Elongated  transverse  outer  end  portions of  the  mounts longitudinally extend radially relative to the motor axis and are rigidly secured along their lengths to the outer side of the blower housing inlet  side wall,  thereby serving to brace  it against undesirable flexure.   Transverse bending flexure of the mounts is  facilitated in one embodiment thereof by relatively large openings formed through the motor ends of their bodies, and depressions formed in the trailing body edges receive portions of the  cross-sectionally  rounded  peripheral  side  wall  edge  to provide mounting clearance space therefor and the ability to use the same mount on housings having different inlet diameters.

Title: Suppression of immune responses of oligomeric forms of antigen of controlled chemistry
Inventor: DINTZIS HOWARD M
IPC: A61K47/48
Filed: 1991-12-17
Abstract: The present invention relates to a method of specifically suppressing an undesired immune response in a mammal suffering from such a response. The method comprises: i) preparing a construct comprising at least one discrete antigenically recognizable moiety corresponding to an antigenic determinant of an antigen causing the undesired immune response bound to a pharmacologically acceptable carrier wherein the number of the moieties bound to the carrier and the spacing of the moieties on the carrier are such that the construct does not elicit an immune response to the moieties but does directly compete with the antigen for receptors on an immunocompetent cell that recognizes the determinant, and thereby the construct specifically suppresses the undesired inmune response;  and ii) administering the construct to the mammal in an amount such that suppression of the undesired immune response is effected.  The invention further relates to constructs suitable for use in the above method and to methods of making same.

Title: Process and apparatus for the control and regulation of the pressing process of a brick press
Inventor: HAUSER HANS U
IPC: B28B3/02
Filed: 1992-10-02
Abstract: A brick press for the production of formed bodies from free-fa.owing materials has a measuring and comparison device, in which pressing force and press path are detected from the beginning of the pressing process and are compared with a preset pressure curve, which represents the pressure/path setpoint value of the pressing process. Any deviations from the force/path setpoint value determined outside a range of tolerance of pressure curve are used as a signal for early ending of the pressing process.      Reject formed bodies resulting in this case can be crushed effortlessly and again recycled in the initial material to be pressed without subsequent treatment. A process is also disclosed for the control and regulation of the pressing process.

Abstract: In a method to modify the chemistry of a portion of  the  surface  of an article,  the surface is placed adjacent an electrode in a plasma chamber, the distance to the wall of the chamber being at least five times the size of the electrode.  A plasma of very high power density is generated in a discharge volume surrounding the electrode so that the surface area closest to the electrode   receives   a  very   intense  plasma  which, diminishes with increasing distance from the discharge volume thus forming a chemical gradient on the article surface.   The preferred article is a tube having one closed end, and the gradient may be formed from either the closed end or the open end.  The gradient may be of decreasing    glass-like    character   or   decreasing plastic-like character.
