Title: Method of preparing 4-aminodiphenylamine
Inventor: ALLMAN JAMES M
IPC: C07C209/30
Filed: 1992-04-03
Abstract: A method of producing 4-ADPA is disclosed wherein aniline or substituted aniline derivatives and nitrobenzene are reacted under suitable conditions to produce 4-nitrodiphrenylamine ar substituted derivatives thereof and/or 4-nitrosodiphenylamine or substituted derivatives thereof and/or their salts, either or both of which are subsequently reduced to produce 4-ADPA or substituted derivatives thereof. The 4-ADPA or substituted derivatives thereof can be reductively alkylated to produce p-phenylenediamine products or substituted derivatives thereof which are useful as antiozonants. A second embodiment of the invention is the tetrasubstituted ammonium salts or alkyl substituted diammonium salts of 4-nitrodiphenylamine, 4-nitrosodiphenylamine and the substituted derivatives thereof wherein each substituent of the tetrasubstituted ammonium ion is independently selected from the group consisting of alkyl, aryl and arylalkyl groups and each alkyl substituent of the alkyl substituted diammonium salt is independently selected.

Title: Coated abrasive having a coating of an epoxy resin coatable from water
Inventor: LEE CHONG S
IPC: B24D3/28
Filed: 1992-11-26
Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a coated abrasive having a plurality of abrasive grains bonded to a backing by means of one or more binders, in particular a binder formed from an epoxy resin that is coatable from water.          Coated abrasives comprise a backing having abrasive grains bonded thereto by one or more binders. These binders typically comprise a glutinous or resinous adhesive, and may optionally contain one or more additives. Binders are typically applied by coating from an organic solvent.          In recent years, however, there has been a need to coat these resins exclusively from water on account of increasingly stringent pollution legislation.  Accordingly, it is desired to provide a coated abrasive article having an overcoating containing an epoxy resin and a grinding aid, wherein the epoxy resin can be coated from water. This invention provides a coated abrasive article having a coating comprising a composition formed from an epoxy resin that is capable of being coated from water, a curing agent, and optionally a grinding aid dispersed in the epoxy resin. It is preferred that the coat containing the epoxy resin and the grinding aid be the outermost coat of the coated abrasive article, e.g. the size coat or supersize coat, in order to position the grinding aid in direct contact with the workpiece being abraded.

Filed: 1993-07-09
Abstract: A method and apparatus for producing blood component products.  In  one  embodiment,   a  plurality  of  a predetermined type of blood component is harvested from a source  of  whole  blood.    At  least  two  on-line  yield determination techniques are utilized to determine the yield  of  the  harvested  blood  components.    One  is  a predetermined yield prediction technique and the second is a predetermined yield monitoring technique, each of which are individually calibrated in relation to a predetermined off-line yield determination technique.  The predetermined yield prediction and monitoring techniques each provide the yield of the harvested blood components and each is then utilized to provide a determined yield.  Consequently, when the harvested blood components are packaged the determined yield may be associated therewith,  thereby providing a blood component product.

Filed: 1992-03-12
Abstract: The rate of viral resistance developed during the course of treatment with antiviral nucleoside analogues is reduced by administering dsRNAs early in the treatment of the infection or in later stages when viral genetic mutation has occured to restore susceptibility of the virus to otherwise ineffective antiviral agents.  Delaying and/or reducing the appearance of nucleoside analogue resistant retroviruses, particularly HIV, is achieved with mismatched dsRNAs notably in the peripheral blood mononuclear cells, especially the CD4 lymphocytes.

Patent CA-2105544-A1 (CA)
Inventor: SCHMIDT DOUGLAS C
IPC: H04L69/40
Filed: 1993-09-03
Abstract: An error rate monitor determines, on a safe and effective basis, when a transmission link is experiencing excessive errors and should be taken out of service. Safety is assured by preforming a changeover when the amount of data awaiting transmission via the link gets too high; effectiveness is assured by keeping the link in service despite short term error bursts that can be overcome by data retransmission. In one monitor arrangement, errors that occur in the transmission link during a fixed time interval are monitored. If one or more errors occur in an interval, an increment is added to a counter (originally initialized to zero). If no errors occur in the interval, a decrement is subtracted from the counter, to a minimum of zero. The increment and decrement values are determined as a joint function of (a) the round trip delay on the transmission link, (b) the maximum allowable error rate on the link, and (c) the link speed, so that, in general, the increment and decrement values are significantly different. When the counter exceeds a given threshold, T, a changeover is declared. The value of T is determined as a joint function of (a) the maximum amount of data in the messages that should be stored in the transmit buffers when changeover occurs, (b) the maximum allowableerror rate on the link, and (c) the duration of the fixed time interval.
