Patent CA-2068215-A1 (CA)
Inventor: PARKS ROBERT A
IPC: H03M1/52
Filed: 1990-12-14
Abstract: An analog-to-digital converter employs a capacitor circuit for integrating a sample of an input signal during a predetermined interval of time and, thereafter, the capacitor is discharged at a predetermined rate until the integration voltage is equal to that of a reference. The discharge time serves as a measure of the amplitude of the input signal. A measurement interval is established which is equal to an integral number of cycles of each of the possible values of frequency of the A.C. excitation. The signal integration interval has a duration less than or approximately equal to the shortest period of the A.C. excitation, this being the period of the highest frequency A.C. excitation. The signal integration is repeated periodically at each third half-cycle of the highest frequency excitation so that the total integration time experienced during positive half cycles is equal to that experienced during negative half cycles of any of the plurality of excitation frequencies. This cancels the effect of noise due to signal polarity.

Title: Process for the preparation of oligomeric polyisocyanates and their use
Inventor: SCHOLL HANS-JOACHIM
IPC: C08G18/79
Filed: 1992-06-11
Abstract: The present invention relates to a process for the preparation of oligomeric polyisocyanates in which (a) a portion of the isocyanate groups of organic poly-isocyanates is oligomerized in the presence of catalysts that accelerate the dimerization of isocyanate groups, and (b) the oligomerization reaction is terminated after reaction of about 5 to about 45% of the isocyanate groups present in said organic polyisocyanates by the addition of a catalyst poison comprising a silylated acid corresponding to the formula X-[Si(CN3)3]n wherein X represents the neutral acid residue obtained by removal of the acidic hydrogen atoms from an n-basic acid having a pK a value of at most 3, other than a hydrohalic acid, and n is an integer of 1 to 3.        The invention also relates to the use of oligomeric polyiso-cyanates obtained by this process, optionally in admixture with unreacted starting polyisocyanates and/or optionally with the isocyanate groups blocked by blocking agents, as polyisocyanate component for the preparation of polyurethane resins by the isocyanate polyaddition process.

Title: Method for enhancing antibody transport through capillary barriers
Inventor: PARDRIDGE WILLIAM M
IPC: A61K47/48
Filed: 1991-03-06
Abstract: A method for increasing the transcytosis of an antibody across the microvascular barrier and into the interstitial fluid of organs is disclosed. The method consists of cationizing the antibody with a cationizing agent to increase the isoelectric point of the antibody by between about 1 to about 7 to produce a cationized antibody having an isoelectric point which is less than about 11.5. The increased rate of transport across the microvascular barrier of organs makes such canonized antibodies useful for both therapeutic and diagnostic purposes.

Inventor: GYGER ROGER F
IPC: F25D13/06
Filed: 1991-05-06
Abstract: A food freezer'(10) having a mechanical refrigeration system (54) comprising first (56) and second (58) closed-loop fluid circuits, wherein the first fluid circuit (56) employs carbon dioxide as its refrigerant and transfers heat to the second fluid circuit (58), which in turn transfers heat to the environment or to another fluid circuit. In the first fluid circuit evaporator (60), carbon dioxide is maintained at pressures between 60.4 psig and 120 psig. In a preferred embodiment of the invention, the freezer (10) employs at least two separate blowers (44); (86) or fans for circulation of air or other gas in the freezer enclosure. One blower/fan (44) operates continuously to maintain circulation of cold air or gas in the freezer (10). The other blower/fan (86) operates inter-mittently or at variable speeds to vary air flow across the evaporator (60), and thereby increase or decrease heat transfer from the freezer (10) interior to the first fluid circuit evaporator (60) to maintain the freezer (10) interior at a desired temperature or within a desired temperature range.

Title: Method of manufacturing sterilized organic fertilizer and apparatus therefor
Inventor: SHIRLEY BRUCE L
IPC: C05G1/00
Filed: 1991-04-26
Abstract: ABSTRACT          A method and device for sterilization of organic fertilizer, wherein the method includes the step of formulating components of the composite fertilizer such that constituents are treated with an acid to form a mixture having a pH less than (7), i.e., acidic.  The bacteria contained in the mixture adapt within a short time to the acidic environment and thrive therein.  The components are then further treated with a basic material, such as anhydrous ammonia NH3.  The transition from strong acidic to mild acidic or basic pH is of such a severe nature that the bacteria cannot adapt to the changed pH and heat changes and as a result die within seconds.  The finished fertilizer product is thereby rendered sterile of bacteria which would otherwise thrive and consume the nitrogen within the fertilizer.  The fertilizer held nitrogen is then safely locked into the organic fertilizer.  The nitrogen is later released on application to soil when soil-borne bacteria feed on the fertilizer.  The bacteria consume the nitrogen, and alter the constituents making the elements assumable as nutrients for growth of plants.

Title: Oligosaccharide oxazolines, oligosaccharide conjugates and methods of preparation thereof
Inventor: COLON MARCELO
IPC: C07H13/04
Filed: 1991-05-24
Abstract: This invention relates to a method of producing peracetyloxazolines from peracetyl saccharides. The method involves reacting the starting material, a peracetyl saccharide, with a reagent combination, to directly produce the peracetyl oxazoline. This method maybe used for the activation of oligosaccharides, wherein an oligosaccharide containing a reducing GIcNAc terminus is activated by the formation of an oxazoline at the terminal GIcNAc, and then coupled with a bifunctional spacer to provide an oli-gosaccharide-spacer conjugate. The activated oligosaccharide-spacer conjugate is then coupled to a protein, such as granulocyte colony stimulating factor or .gamma.-interferon, providing a neoglycoprotein conjugate. The invention provides a method for forming neoglycoprotein conjugates which may improve biological and physiochemical properties of the protein. For example, serum life-time or efficiency of drug delivery of the peptide to a target organ or cell may be improved.

Abstract: A  data  processing  system  for  regulating  access  to  a communication  network  is  disclosed  herein.   The  data processing  system  employs  a  component  that  can  be implemented in hardware logic or software.  The component regulates access to the priority queue or transmit channel that is attached to the shared medium local area network section.  All  access  to  the  priority  queue  or  transmit channel must pass through this component,  thus subjecting all communication transactions to rejection or tracking by the component. The component allocates a frame size based on the information to be transmitted and the priority to assure the transmission will be completed in line with the quality of service required.  The component monitors the rate and size of messages to assure that an application's actual throughput does not exceed its negotiated throughput.  The component, moreover, is capable of operating in correction mode  where  throughput  and  frame  size  violations  are prevented  and  reported.   Alternatively,   the  component operates in detection mode where violations are recorded and reported to an application.

Title: Fcc regeneration process and apparatus for reducing nox
Inventor: AVIDAN AMOS A
IPC: C10G11/18
Filed: 1993-06-22
Abstract: Oxides of nitrogen (NO x) emissions from an FCC regenerator are reduced by forcing the regenerator to operate intermediate full and partial CO burn mode. Operating with less than 1 mole % O2, and up to 1 or 2 % in the flue gas, creates conditions which oxidize nitrogen compounds in coke on spent catalyst to NO x, and simultaneously convert NO x in the regenerator to nitrogen. A downstream CO boiler can burn this low CO flue gas without producing large amounts of NO x. Most NO x emissions can be eliminated. An apparatus, with the regenerator air:coke ratio controlled by both CO and O2 analyzers monitoring regenerator flue gas, is also disclosed.

A mechanism, responsive to diaphragm deflection, determines pressure of the melt.  Another mechanism is included for determining the temperature of the melt and a further mechanism is included for indicating longitudinal movement of the plunger.  From such determinations, the PVT characteristics and the apparent shear viscosity characteristics of the polymer melt can be obtained.
