Title: Process for the preparation of activated chitosans and their use in the preparation of chitosan derivatives
Inventor: MEISTER CHRISTOPH
IPC: C08B37/08
Filed: 1990-02-08
Abstract: HOECHST AKTIENGESELLSCHAFT - KALLE Works Abstract of the disclosure:            Process for the preparation of activated chitosans and their use for the preparation of chitosan derivatives The invention relates to a process for the preparation of activated chitosans,  in which process a chitosan is reacted with an acid for salt formation,  preferably followed by a reaction with a base. The addition of acid and the addition of bases which is preferably to be effected in the activation are carried out in a suspend-ing agent which largely prevents the chitosan salts from dissolving,  suitable  suspending  agents  can  be  both aqueous  solutions of inorganic salts and organic or aqueous-organic solvents.            The invention also relates to a process for the prepara-tion of both water-soluble and water-insoluble chitosan derivatives by reacting the activated chitosans with reagents which are generally suitable for the reaction of polysaccharides or amines.

Title: Monoclonal antibody to novel antigen associated with human tumors
Inventor: HELLSTROM KARL E
IPC: C07K16/00
Filed: 1990-02-16
Abstract: ABSTRACT      The present invention is concerned with a novel monoclonal antibody which binds strongly to a protein antigen associated with human tumors, including carcinomas of the colon, breast, ovary and lung, as well as melanomas and sarcomas.  The antibody binds to normal human cells to a much lesser degree than to tumor cells. The antibody finds use both in diagnostic methods such as the detection of malignant cells associated with tumors and in therapeutic methods for treatment of humans with tumors.  Also disclosed is a novel 100,000 dalton glycoprotein antigen found on the cell surface of human tumor cells.  The amino terminal amino acid sequence of this antigen is:     W-Y-T-V-N-S-A-Y-G-D-T-I-I-I-P-X-R-L-D-V-P-Q-N-L-M-F   in which X represents an unidentified amino acid.

Title: High speed packet resequencing system
Inventor: STEVENSON DANIEL S
IPC: H04Q3/00
Filed: 1990-03-07
Abstract: HIGH SPEED PACKET RESEQUENCING SYSTEM            Abstract of the Disclosure There is provided a resequencing process capable of sorting out-of-sequence cells as they transit through a high speed switching network, while maintaining a desired level of performance.   The process comprises the steps of adding a time stamp to an incoming cell, prior to entering the switching network, wherein the time stamp corresponds to the current system time.  Cells leaving the switching network are forwarded to a series of cell storage buffers as they exit the switching network.  The status of each cell storage buffer is monitored such that an incoming cell can be directed to an empty buffer.  The cell delay time of the buffer can then be set by comparing the difference between the cell time stamp and the current system time to the amount of time the incoming cell must be delayed before reaching an age maturity of k.  Once the cell has reached maturity, they are allowed to exit the storage buffer.            - i -

Title: Palm pad
Inventor: HEARN EDWARD J
IPC: B25B23/00
Filed: 1990-06-04
Abstract: - ABSTRACT -In using a manual torquing tool such as a screw driver to turn a threaded fastener, it is known to use the palm of the other hand to apply additional axial load in order to increase turning ability and reduce slippage and wear on both tool and fastener.          In this invention, a circular curved pad is provided to the palm of the pressing hand to transmit load to the handle without direct contact between the handle and the palm, thus reducing friction and eliminating discomfort to the hand.    Said invention is positioned with the convex surface towards the palm, and can be held in place by partial closure of thumb and little finger. The invention is bi-directional, as the torque tool can be rotated either clockwise or counterclockwise, and can be used in either hand. A concentric profile on the concave surface provides a centering action on the tool handle. The invention would be provided in a variety of colours common to hand tools, and would accomodate a full range of hand torque drivers for sockets and all varieties of screwdrivers.

Abstract: ABSTRACT        An irradiator furnace is connected to a square waveguide  for propagation  of  microwave  and  provided through a top wall with a slot.   A conveyor bucket conveys sealed containers along  the  slot with  lower portions  of  the  sealed  containers  being  inserted through the slot into the  irradiator furnace.     The irradiator furnace includes therein a rail which ex-tends from the lowest level at an inlet of the irradia-tor furnace to the highest level at an outlet of the irradiator furnace so as to support the sealed contain-ers.  The hot air furnace is provided above the irradi-ator furnace.   A narrow passage  extending  from the outlet of the irradiator furnace is directly followed by a thermostatic station utilizing an IR heater.   So the sealed containers are sterilized.      To feed the sealed containers to the conveyor bucket of the sterilizer,  a sealed container feeding hopper comprising a conveyor belt, a screw and a feed-ing wheel is provided.  A  sensor is provided to detect whether individual turns of a screw groove are properly loaded with the sealed containers or not and auxiliary feeding guides operatively associated with the sensor to feed the sealed containers to the screw.

IPC: C02F1/42
Filed: 1990-07-31
Abstract: ABSTRACT OF THE DISCLOSURE A container has a removable multi-bed, water purification filter with two beds or compartments that are separated by a fibrous member.  The multi-bed filter reduces lead, aluminum, chlorine, or the like, from water.  The container has upper and lower chambers with the multi-bed filter therebetween which permit a batch filtering of water in response to a gravity feed so that water pressure is not required in order to filter water.

Patent CA-2028423-A1 (CA)
IPC: D04H3/04
Filed: 1990-10-24
Abstract: The specification of the instant invention discloses improvements in methods for making various types of mats of fiberous material.  In particular, the improvements relate to methods for making continuous fiber glass strand mats using reciprocating strand feeders and a programmable motion controller to control both the rate of reciprocation and the rate at which strand is deposited from the feeders onto a moving conveyor so as to form mats of uniform density and thickness.  Electric servomotors are used to reciprocate the feeders and also deposit strand therefrom.  A closed-loop feedback circuit is used to accurately monitor and control the position of the feeders with respect to the conveyor as well as the rate of strand deposition.  Methods for using the programmable motion controller described herein can increase the uniformity of needled, resin-impregnated, and uni-directional fiber glass mats.

Abstract: Atty. Dkt.:  910084/W          ABSTRACT OF THE DISCLOSURE       Measurements of acids in air can be greatly falsified by the content of carbon dioxide in the air in spite of the low solubility of carbon dioxide in water and its low dissociation constant.  When the measurements are made after a simple absorption of the acid residues in the air in an absorption solution.  The air separated from the absorption solution on its way to measurement is cleaned of carbon dioxide by exposure to silica gel and soda-lime and then is used to clean the absorption solution of carbon dioxide in a similar exposure of air to the liquid.  The measurement of the acidity of the solution thus cleaned of carbon dioxide provides reliable measurements of strong acid residues in air and can be carried out on a continuous basis.
