Title: Liposome preparation and material encapsulation method
Inventor: COLLINS DAVID SAMUEL
IPC: A61K9/127
Filed: 1994-11-03
Abstract: The present invention relates to a method of producing liposomes useful for encapsulating and delivering a wide variety of biologically active materials.  The invention provides liposomes and a production method which is simple, feasible and inexpensive for the large-scale commercial manufacturing of liposomes and encapsulated materials. The method involves the formation of a liposome dispersion in the absence of an organic solvent or detergent, one or several cycles of freezing and thawing the liposomes, and dehydration of the liposome dispersion to form a lipid powder. When desired, the lipid powder is hydrated in the presence of the biologically active material whereby the material is encapsulated in reconstituted liposomes. The method can also include combining the liposome dispersion with a bulking agent prior to the dehydration and formation of the lipid powder. The addition of the bulking agent facilitates the handling of the lipid powder as well as its rapid dispersal upon hydration.

Title: Heat treating and removing cores from castings
Inventor: CRAFTON SCOTT P
IPC: F27B9/00
Filed: 1995-01-10
Abstract: Waste gases generated in the process of manufacturing cores and castings are collected and inventively routed to a heat treating furnace (12) for incineration. Additionally, as a portion of the waste gas is being routed, it is put to use in the reclaiming of uncured scrap materials and the reclaiming of sand within the furnace. Additionally, provisions are made for decreasing the height of the furnace by decreasing the height of hoppers therein and increasing the size of the base of the hoppers to maintain proper flow of reclaimed sand and portions of core materials being reclaimed therein toward the base of the hopper. Multiple fluidizers (18) are employed in the base of the hopper to accomodate for the increased size of the base of the hopper and maintain optimum flow of materials toward the base and optimum fluidization of the materials within the hopper.

Title: Novel peptides for heparin and low molecular weight heparin anticoagulation reversal
Inventor: WAKEFIELD THOMAS W
IPC: C07K14/00
Filed: 1994-11-10
Abstract: Less toxic agents for reversal of heparin or low molecular  weight heparin anticoagulation which are synthetic protamine-like polycationic peptides having a total cationic charge which is less than that of n-protamine.  In preferred embodiments, arginine residues of n-protamine are replaced with lysine residues for ease of manufacture. Selective positively charged arginine residues have been replaced with an uncharged amino acid residue or its analog, such as glycine or glutamine, in order to reduce the total cationic charge on the polycationic peptide to the range of about [+14] to [+18], preferably [+16] to [+18]. In specific embodiments, there are sequences of 29 and 32 amino acid residues wherein 4 to 5 clusters of 2 to 4 positively charged amino acids are separated by 2 to 6 neutral amino acids. The C-terminus and the N-terminus can be modified to mitigate against in vivo degradation by carboxypeptidases and aminopeptidases.  Another modification, specifically use of .alpha.-helix forming amino acids, such as glutamic acid, further promotes anticoagulation reversal.

Patent CA-2178776-A1 (CA)
Inventor: ROBINSON VICTOR E
IPC: C25C7/08
Filed: 1996-06-11
Abstract: This invention concerns a method and an apparatus for automated stripping of electrodeposited zinc sheets from aluminum cathode base plates.  This is achieved using a stripping mechanism that has a single pivotable stripping arm assembly linearly movable on the side of a rack of cathodes suspended vertically in parallel alignment with one  another.  The  single  stripping  arm  assembly  is automatically moved and positioned in alignment with each cathode and then pivoted so that the knives mounted at the end of the stripping arm assembly wedge between the cathode base plate and the zinc sheets on each side of the cathode and then proceed to peel or strip the zinc sheets from the cathode base plate. This is done until each cathode is so stripped. The apparatus is preferably provided with wheels for mobility.

Patent CA-2179187-A1 (CA)
Inventor: MARESCA JOSEPH W JR
IPC: G01M3/28
Filed: 1994-12-16
Abstract: An apparatus for detection of leaks in pressurized pipelines which utilizes a large pressure vessel (610) and a small measurement vessel (612). The measurement vessel (612) magnifies level changes during leak detection tests. The apparatus is connected to a pipeline through the measurement vessel (612). The entire system can be filled with liquid from the pipeline by opening a valve (V2) between the measurement (612) end pressure (610) vessels. leak detection tests are conducted by measuring changes in volume with the measurement vessel (612) over time while the pressure over the liquid in the pressure vessel (610) and measurement vessel (612) is maintained approximately constant. During tests, liquid communication between the measurement vessel (612) and pressure vessel (610) is prevented by closing the valve (V2) between them but vapor communication between the vessels is permitted.

Patent CA-2193077-A1 (CA)
Title: Telemetry Access Arrangement
Inventor: GARLAND STUART MANDEL
IPC: H04M11/00
Filed: 1995-01-26
Abstract: This invention relates to a method and apparatus for accessing customer meters and for controlling customer devices over a telephone line. A connection using only a single distinctive brief burst of power ringing or tone is established over a customer line between a central office and customer station equipment to alert both the customer and the customer premises equipment (CPE) or a short burst of tone to alert the CPE. The connection is between a data accessing device such as a meter reading controller and a customer premises device such as a meter interface unit. Signals are exchanged over the connection between these two units without alerting the customer via a ringing signal and without changing the supervisory state of the customer's station equipment from on-hook. The connection can also be used for controlling devices such as air conditioning units, in order, for example, to avoid overloads in a power distribution system. The voice switching network of the central office is used for making the connection between the meter control unit and the meter interface unit. Advantageously, this arrangement can allow a large number of utility meters and controlling devices to be accessed remotely using existing telephone plant. The short distinctive burst of power ringing or tone alert may be used to alert the customer premises equipment (CPE), the customer telephone, or both.
