Patent CA-2043896-A1 (CA)
IPC: F25J3/04
Filed: 1991-06-05
Abstract: ABSTRACT   This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein a nitrogen rich, oxygen rich and argon rich product are generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Moderate pressure, e.g., 25-80 psia nitrogen is generated with enhanced nitrogen product purity and greater recovery of both nitrogen and argon by effecting a high boil-up rate in the bottom of the lower pressure column, thereby creating a reduced liquid flow/vapor flow ratio (L/V) and utilizing a higher than customary nitrogen reflux to the top of the lower pressure column, where the concentration of oxygen in nitrogen is less than about 10 ppm by volume or the nitrogen purity is at least about 99.5% by volume. Refrigeration to drive the system is obtained by recovering the energy from the waste nitrogen stream and oxygen vapor from the lower pressure column. A second method for obtaining refrigeration is to withdraw oxygen as a bottoms liquid from the lower pressure column, expanding that liquid to a lower pressure and using it to condense the nitrogen vapor generated in a higher pressure column which has been expanded in a turbo-expander to provide the refrigeration.

Title: Apparatus for the wet end coating of paper
Inventor: RACINE JEAN-GUY
IPC: D21H23/28
Filed: 1991-10-15
Abstract: Abstract An apparatus for wet-end coating a web on a papermachine  before  the  web  enters  the  dryer comprises  a  first  endless  porous  fabric  passing around a first couch roll equipped with a suction box.   As the web passes around the first couch roll, a first applicator applies a coating on a top side of the web with the first suction box drawing some of the coating color onto and through the web so as to coat the top side thereof.   The web is then conveyed on a second endless porous fabric which passes around a second couch roll equipped with a second suction box.    In this case,  the top side of the web is in contact  with  the  second porous  fabric  so  that  a second  applicator  may  apply  coating color  on  the bottom side of the web with the second suction box, as above,  drawing some of the coating color onto and through  the wet  web  for  coating the  bottom  side thereof.   The applicators may be rolls which contact the  web.     Recovery  systems  may be  provided  for returning  the  coating  color  recuperated  by  the suction boxes to the applicator rolls.    In such a case,  it may be necessary to treat the recuperated coating color before returning it to the applicator rolls.     Asides  from  coating,   bonding  agents, bleaching   agents   and  various  other  substances including dry substances that can enhance the various properties of the paper or paperboard may be applied by the above applicators.

Title: Process for the vapor-phase thermal cracking of dicyclopentadiene and a process for the manufacture of high purity dicyclopentadiene
Inventor: NAKAMURA TAKAO
IPC: C07C13/15
Filed: 1992-04-15
Abstract: Recently, as a process for manufacturing cyclopentadiene resin-shaped articles, an attention has been given to reaction injection molding (RIM).  To conduct RIM, it is necessary to use high purity dicyclopentadiene (DCPD) as the raw material. Vapor-phase thermal cracking of DCPD is usually used as a step of process for manufacturing high purity DCPD.  Hithertofore, when coducting thermal cracking of DCPD, coke formation within cracking tubes is the most serious and troublesome problem.  A vapor-phase thermal cracking process for resolving the problem by a very simple procedure is described herein.  Further, a process for manufacturing high purity DCPD suitable as a raw material  for  use in RIM utilizing  the vapor-phase thermal cracking process just mentioned above is also described.

Title: Surgical drill guide
Inventor: TROTT A FRANK
IPC: A61B17/17
Filed: 1992-06-23
Abstract: A drill guide is disclosed in which a cylindrical guide tube is secured to a handle so that it may not be easily longitudinally moved in either direction without the user engaging a thumb activated locking mechanism. The cylindrical guide tube passes through a conically tapered cylindrical bore within the drill guide handle and a similarly tapered split collet is interposed concentrically between the exterior of the cylindrical guide tube and the interior of the bore. The collet is provided with a plurality of longitudinally extending lobes which are sufficiently resilient that movement of the collet to its proximal-most position causes the lobes to squeeze inwardly against the cylindrical guide tube.      Frictional engagement between the collet lobes and the guide tube prevents the latter from moving until the collet is moved distally to release pressure on the lobes. The collet is normally biased proximally by a leaf spring attached to the drill guide handle and a thumb activated lever is provided to move the leaf spring distally to release pressure on the lobes and unlock the cylindrical guide tube.

Title: Equalizer training in a radiotelephone system
Inventor: BACKSTROEM TOMAS
IPC: H04L25/03

Abstract: Reception of a transmission in a radiotelephone system including an equalizer is improved by training the equalizer using a synchronization portion of the transmission having a data pattern chosen for its correlation properties and retraining the equalizer using a portion of the transmission transmitted for a different purpose. In particular, the portion of the transmission transmitted for a different purpose may be the digital verification color code transmitted during each burst in a digital cellular mobile radiotelephone system. Reception quality is increased by training the equalizer at more frequent intervals without increasing transmission overhead.
