Patent CA-1303020-C (CA)
Inventor: BRIEKE HANS-GUENTER
IPC: F28F9/02
Filed: 1987-11-06
Granted: 1992-06-09
Abstract: ABSTRACT          The invention relates to a device for the heat exchange between a recycle gas leaving an NH3 converter and water, with recycle gas-charged heat exchanger tubes which have a gastight connection to at least one tubesheet separating a pressure-resistant channel from a heat exchange chamber, the tubesheet be-ing additionally provided with cooling bores for a flow of water or of a water/steam mixture.  The object of the present invention is to provide for a solution which allows cooling to be safely main-tained even for an arrangement other than horizontal of the tubesheets, i.e. cooling should be effective independently of the position of installation of the tubesheet.  The problem is solved, as per this invention, by the fact that the cooling bores, as seen from the heat exchanger side, do not penetrate the tubesheet completely and are, in their base area, connected via feed bores to a cooling water supply line, the water being fed to the heat exchange chamber via the cooling bores.

Title: Method of decontaminating surfaces on or near living eukarotic cells with vapor phase hydrogen peroxide
Inventor: SCHMIDT WILLIAM C
IPC: A61L2/24
Filed: 1987-11-27
Granted: 1992-03-17
Abstract: Abstract of the Disclosure A method of selectively destroying organisms within a predetermined area is comprised of the steps of introducing vapor phase hydrogen peroxide into the predetermined area at a rate sufficient to cause a predetermined concentration of hydrogen peroxide to be reached while preventing any substantial change in pressure or condensation of the hydrogen peroxide within the predetermined area.  The predetermined concentration is maintained for a period of time sufficient for destroying undesirable organisms but insufficient for harming desirable organisms.  When the predetermined period of time has elapsed, the vapor phase hydrogen peroxide is removed from the area.

Patent CA-1321310-C (CA)
Title: Head box for a paper machine or the like
Inventor: EGELHOF DIETER
IPC: D21F1/00
Filed: 1987-12-23
Granted: 1993-08-17
Abstract: Abstract of the Disclosure A head box has a preferably fixed flow-carrying wall  and  a  movable  flow-carrying  wall  defining  a nozzle-like  stock conduit  and  an  outlet  slot.    The movable wall is provided with an adjustable profile bar at the stock outlet slot.  For coarse adjustment of the slot width,  two  lifting  devices  act  on the movable flow-carrying wall.   Fine adjustment of the slot width is  performed  by  adjustment  spindles  acting  on  the profile bar.  To improve adjustment of the stock outlet slot by the movable wall and to use the profile bar adjustment to perform very small corrections to the slot width, a front end section of the movable wall located in the region of the stock outlet slot  is  flexibly constructed with respect to  the remaining part of the wall,  and a plurality of adjustment units are spaced across the machine width and act on said flexible end section directly in front of the stock outlet slot.  In this  way,  the  movable  wall  can  be  adapted  with relatively high accuracy to the contour of the fixed wall on the outlet  slot side by means of the adjustment units  acting  on  the  flexible,  end  section.    The immersion  depth  of  the  profile  bar  into  the  stock conduit therefore is  substantially constant over the machine width.  Cross currents and different velocities of the stock flow are avoided and the properties of the paper resulting from the paper machine are improved.

Title: Automatic primary color convergence alignment system for projection television
Inventor: TSUJIHARA SUSUMU
IPC: H04N9/28
Filed: 1988-02-25
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE:           An automatic primary color, component convergence alignment system for a color television display apparatus is presented whereby sections of an alignment pattern are periodically displayed in peripheral regions of the television screen, in each of the primary colors during respective successive correction intervals, the patterm positioned such as to fall upon photo-sensitive devices disposed at the screen periphery.  Adjustment of pattern position is executed during each correction interval, based on position data derived from output signals from the photo-sensitive devices, such as to align the alignment pattern with predetermined reference positions.  During each period between these sets of correction intervals, the position data thus derived are held stored and are continuously utilized for controlling the deflection of respective electron beams used in generating the primary colors, to thereby implement automatic convergence alignment adjustment.

Title: Method for rapid induction heating of molten glass or the like
Inventor: MATESA JOSEPH M
IPC: C03B5/00
Filed: 1988-03-03
Granted: 1993-01-05
Abstract: ABSTRACT     A melt of a material such as glass is inductively heated at a stage intermediate an initial liquefying stage and a refining stage.  The function of the intermediate induction heating stage is essentially limited to raising the temperature of the melt a relatively minor amount to a refining temperature.  Therefore, the induction heating stage may be compact with an intensified heating rate and rapid throughput, thereby permitting the induction heating zone to be a "cold" walled vessel without an appreciable effect on efficiency.

Title: Method of rapidly abandoning large, cavities washed-out in rock salt
Inventor: BOULANGER ALAIN
IPC: B65G5/00
Filed: 1989-06-02
Granted: 1993-03-23
Abstract: A B S T R A C T            After they have been washed out, cavities (4) in rock salt contain a large quantity of brine (8) at a temperature which is lower than the temperature of the surrounding formation (2). This means that the cavity cannot be sealed quickly because the brine will expand progressively as it heats up.  The method of the invention serves to shorten the time period between the end of working the cavity for salt and being able to abandon the cavity finally from about 30 years to about 2 years.  The method consists in injecting quantities of a mixture (12) into the cavity (4), the mixture being of greater density than brine (8) and being capable of setting, with equivalent quantities of brine (8) being returned to the surface, and then in keeping the cavity (4) open after it has been completely filled with mixture (12) for as long as it takes the rock salt (2) to creep and fill up the shrinkage voids which appear during setting of the mixture (12), after which the cavity (4) can be sealed.  To do this, it is advantageous to make use of waste material for constituting the mixture (12).
