Patent CA-1302825-C (CA)
Inventor: RANFORD ALAN B
IPC: A61M1/00
Filed: 1988-02-12
Granted: 1992-06-09
Abstract: ABSTRACT     A collection container for body fluids includes a bag having walls (66,68) adapted to move with relatively stiff and flexible sheet members(76,78).  A squeezing force applied to the side edges of the members (76,78) causes them to bend outwardly thereby expanding the bag. The members have inwardly extending slots (106-112) which allow the bag to adopt a generally conical shape at top and bottom in the expanded condition.       The specification also discloses a filter (120) between the bag inlet (22) and outlet (30) which filters incoming liquid but allows gas to pass directly from inlet to outlet without flowing through the filter.
Patent CA-1341232-C (CA)
Inventor: FLEISCHER HANS-JOACHIM
IPC: B01J23/86
Filed: 1988-02-26
Granted: 2001-05-15
Abstract: The invention relates to a ferritic, heat-resistant steel whose behaviour at high application temperatures is improved by the combined addition of oxygen affine elements. Apart from stabilizing the electric resistance of heating elements by addition of zirconium, titanium and rare metal, also the creep elongation of the steel is considerably reduced under load at temperatures above 900°C, the thermal stress capacity thus being increased. The resulting complex oxide coating increases the protective function with regard to preserving the metallic cross-section in continuous and/or cyclic heat treatments.      The steel is composed of: max. 0.10 % C max. 0.80 % Si 0.10 to 0.50 % Mn max. 0.035 % P max. 0.020 % S 12 to 30 % Cr 0.10 to 1.0 % Mo max. 1 % Ni 3.5 to 8 % A1 0.01 to 1 % Zr 0.003 to 0.8 % rare metals 0.003 to 0.30 % Ti 0.003 to 0.050 % N remainder Fe and incidental impurities.

Title: Method and apparatus for sorting non-ferrous metal pieces
Inventor: OSTERBERG RICHARD R
IPC: B03C1/23
Filed: 1988-08-24
Granted: 1993-07-13
Abstract: METHOD AND APPARATUS FOR SORTING NON-FERROUS METAL PIECES     ABSTRACT OF DISCLOSURE     Mixed pieces of different non-ferrous metals are sorted by initially moving the pieces through a high density, rapidly changing magnetic flux field, and immediately thereafter, freely moving the pieces along unsupported forwardly and downwardly directed trajectories resulting from the momentum of the pieces, the force of gravity and the magnetically induced repulsive forces developed in the pieces by the flux field. The magnitude of the magnetically induced repulsive forces differ for different non-ferrous metals so that the lengths of the trajectories of generally similar size and shape pieces vary accordingly for separating pieces formed of different metals. The magnetic field is provided by a horizontally axised, rapidly rotating, hollow, liquid cooled, ion wall drum having magnets affixed to its outer surface. The magnets are arranged in rows that are formed of numerous, tile-like, small, permanent magnets which are positioned end to end, with their like polarity ends adjacent. A belt conveyor, which moves the pieces across the top of the drum, has its discharge end pulley coaxially surrounding the drum so that the pieces freely move off the end of the conveyor belt after passing through the magnetic field. Hence, the lengths of the trajectories may be controlled by adjusting the speed of the conveyor, which adjusts the momentum of the pieces, and by adjusting the rotational speed of the drum for adjusting the frequency of the changes in the magnetic field and, consequently, the magnitude of the induced repulsive forces.

Abstract: BALLOON CATHETER     ABSTRACT An inflatable medical balloon is formed by fabricating a tubular preform having a tapered region at the end of the portion where the main body of the balloon will form to enable the corresponding transition section of the blown balloon to have a separately controllable thickness profile.  The preferred method includes providing a tube of a selected resin of wall thickness and diameter suitable for being formed into a balloon, and selectively heating to drawing temperature a defined region of the tube at one or both ends of the . portion of the tube from which the balloon is to be formed.  Tension is applied in opposite directions to respective ends of the heated region to draw the region to a smaller diameter, thereby providing a preform having, at the end of the portion of the tube, a tapered, relatively small diameter region of material that has substantially no crystallization or molecular orientation.  In preferred embodiments a tapered region is provided at both ends of the portion in which the main body of the balloon is to be formed.  Thereafter the tubular freform is heated to blowing temperature and, while heated, a balloon is formed by drawing and blowing the preform including the tapered regions.  The balloon is mounted to form a balloon catheter device.  A dilatation balloon catheter, is also described having wall thickness in the transition region less than 0.001 inch.

An ignition transmission system comprises a plurality of ignition tubes which extend in a longitudinal conjoint relationship in which one tubular member at least overlaps partially another.  The walls of the tubular members are sufficiently thin so that, upon ignition of the ignition strands within one tubular member, communication of the ignition reaction from the first tubular member is transmitted to the ignition strands of the other tubular member.  The ignition system is useful in elongated propellant charges such as ordnance cartridges.

Water is sprayed out of a trough into the freezer cells by means of a spraying device in the form of a bucket wheel which rotates about a horizontal shaft and which comprises two parallel circular discs between which are arranged concave splash blades.  Splash-guard walls as well as a movable splash-guard flap prevent the escape of water from the apparatus.          The defrosted small ice bodies fall on to an inclined grid.  At the beginning of a freezing cycle, the trough is filled via a supply pipe having a valve and, at the end of a freezing cycle, is emptied via a discharge pipe having a valve.

Abstract: Abstract of the Disclosure Mechanical treatment of a pulp slurry of up to 50% O. D. consistency by dewatering and compacting the pulp permanently twists and kinks individual fibers to a degree that is substantially irreversible when they are subsequently subjected to papermaking process steps. The preferred device for imparting such permanent twisting and kinking is a plug screw feeder. Pulp that has been so treated exhibits increased desired drainability in the wet section of a papermachine. Such treated pulp also loses water vapor more easily in the dryer section than untreated pulp, and correspondingly results in less energy consumption in the dryer section of a papermachine. Pulp treated in accordance with the invention also exhibits increased absorbency. Tissue or other soft paper products produced from softwood pulp treated in accordance with the invention exhibit significantly increased softness over such untreated softwood pulp. Pulp treated in accordance with the invention is also useful in enhancing properties, for example bulk, in other paper products.

Abstract: ULTRA-HIGH SPEED TWO-DIMENSIONAL COORDINATE TRANSFORM PROCESSOR       ABSTRACT OF THE DISCLOSURE    An  ultra-high  speed  two-dimensional  coordinate  transform processor   (10)   contains   layers   having   conducting   lines representing coordinate lines in coordinate systems.  Layers in  a first set have  conducting lines representing  a first  coordinate system.  Layers in a second set have conducting lines representing a second coordinate system and are positioned adjacent the  layers in the first set.  A signal is  applied at a point where lines  in the first set  intersect.  This  point represents a  point in  the first coordinate  system.   An induced  signal  is sensed  in  the layers in  the  second  set  at a  point  where  coordinate  lines intersect.  Since the  detected signal  will be  strongest at  the point nearest the  applied signal, the  intersecting point  having the strongest  signal  will  represent the  point  in  the  second coordinate system that is the  transform of the first point.   The processor (10) is  faster than  conventional coordinate  transform methods and is inexpensive to produce.  Accuracy may be  increased by repeating the processing in a smaller coordinate space.
