Patent CA-2048146-A1 (CA)
IPC: F25J3/08
Filed: 1991-07-30
Abstract: ABSTRACT   This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein an ultra high purity nitrogen rich, oxygen rich and optionally an argon rich product are generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Ultra high purity, e.g., nitrogen having less than 0.1 ppm of volatile impurities is generated with enhanced nitrogen product recovery by withdrawing liquid nitrogen from the higher pressure column at an intermediate point and charging that fraction as reflux to the lower pressure column, withdrawing a nitrogen stream which is rich in volatile contaminants from the top of the high pressure column, partially condensing the nitrogen stream and removing the uncondensed portion as a purge stream, and, withdrawing an ultra high purity nitrogen product at a point below a nitrogen vapor withdrawal point at the top of the lower pressure column.  Alternatively, no purge need be taken and the volatile impurities allowed to pass to the low pressure column.  In that case, a nitrogen fraction rich in volatile impurities is removed from an upper portion of the low pressure column, condensed and at least a portion of the uncondensed fraction removed as a purge and the condensed portion returned to the low pressure column.

Title: Device for separating hydrocarbon products from water
Inventor: NOESTHEDEN ANDREW
IPC: B01D17/02
Filed: 1991-12-17
Abstract: A device is disclosed for separating hydrocarbon products or oil from water. The device includes a receiving tank defining a reservoir which receives a mixture of water and oil. The oil floats above the water and thus forms an upper layer in the receiving tank. A skimmer skims the upper layer from the receiving tank and channels the skimmed portion to a pumping chamber. A venturi pump then pumps the skimmed portion from the pumping chamber to a settling tank which then separates the oil and water. The skimmer includes floats which vary the depth of the skimmer as a function of the liquid level in the receiving tank.

Abstract: TITLE OF THE INVENTION     APPARATUS FOR REMOVING COATINGS FROM LARGE SURFACE AREAS AND FOR CLEANING SUCH AREAS            ABSTRACT OF THE DISCLOSURE     Lacquer coatings are stripped from a large surface, e.g. aircraft and vehicle body surfaces, and the surface is simultaneously cleaned by a spraying device that carries at least three spraying units each with at least one, preferably two, spray heads arranged in a row.  Two outer spraying units flank one central spraying unit.  The spraying device is secured to a free end of an outrigger arm on a mobile car-riage, by a wrist mechanism, by a rod linkage and by a mount-ing member tiltable by the rod linkage.  The central spraying unit is directly secured to the tiltable mounting member while the two outer spraying units are secured by lazy tongues operable to track the contour of said large surface.  Distance measuring sensors are arranged to measure the distance between the spray heads and the surface contour to provide respective distance signals to a central processing and control unit which controls the position of the spray heads in response to the distance signals and in response to optimal spacing values stored in a memory of the CPU to assure a desired spacing between the wall and all spray heads.     2692/ar               - 1 -

Title: Lighting control system for pinball games
Inventor: BLEICH CHARLES R
IPC: H05B37/02
Filed: 1992-01-28
Abstract: ABSTRACT     A lighting control system for pinball games employs a lighting circuit board that supports at least one string of lamps connected in parallel.  The lighting board associates a triac with each lighting string for switching the output of an a.c. power supply to each lighting string.  The triacs are controlled responsive to the output of a zero-cross detection circuit, which monitors the a.c. power supply.  The intensity of the lighting strings is independently controllable responsive to conditions on the game playfield by varying the length of time the triac switches power relative to the zero-crossing point of the output of the a.c. power supply.

Title: Cleaning process for radioactive machine shop turnings
Inventor: SORRENTINO PETER P
IPC: C22B1/00
Filed: 1992-03-02
Abstract: ABSTRACT          The present invention relates to a process provided for  cleaning  magnesium thoriated  scrap  turnings resulting from machining  operations.   It results in the recovery of a maximum possible amount of magnesium  thorium  alloy  for  future  use  while ensuring  protection  of  the  environment.   The process reduces to a minimum the amount of the hazardous waste which must otherwise be buried at great expense and with continuing legal liability to the Burying party.  A batch of the magnesium thoriated scrap turnings is rapidly flooded, then washed,  with  a  solution  of  heated  water  and detergent.   Thereupon,  the water,  detergent  and impurities are removed from the scrap turnings, and the  batch  dried.   Thereafter,  ferrous  material present in the washed batch of magnesium thoriated scrap  turnings  is  separated  from  non-ferrous material  and  the  latter  is  classified  into processed  turnings  and  fines.   The  processed turnings, fines and the ferrous material are then separately packaged.

Abstract: The present invention relates to foaming hard surface cleaners, and containers comprising the same in an enclosure. It is known, to provide foaming hard surface cleaners in a metal can together with a propellant to dispense the cleaner. Corrosion may occur on the interior surface of the can, in regions where the can contacts the liquid phase and more especially in regions where the can contacts the vapour phase (ie. in the headspace) and it is known to include in the composition a volatile amine, preferably a primary or secondary amine or ammonia. It is desirable to prevent corrosion in the gas phase while maintaining an acceptable product fragrance. In the compositions disclosed herein, adequate head space corrosion protection is attained with lower ammonia levels, by inverting the can after filling and holding the can in an inverted position for a sufficient length of time for a protective film to form in the eventual upper region of the can and subsequently reverting the can to a conventional attitude to complete formation of a protective film in the lower region of the can.
