Title: Scooped lacrosse head
Inventor: MORROW DAVID
IPC: A63B59/02
Filed: 1996-08-15
Abstract: A lacrosse head having an open frame with sidewalls that curve continuously from the base to the lip of the frame so as to define a curved scoop-like frame geometry when viewed in side elevation. The frame base has an angulated ball rest surface and a shoulder recessed therefrom at which a net is attached to the base. The lip that interconnects the frame sidewalls remote from the base has an outside surface angle that cooperates with the scoop-like geometry of the sidewalls to enhance control of ground balls. The overall scoop-like construction of the head frame provides improved feel during play, and enhanced ball control and pass/shot velocity. The recessed base shoulder, particularly when combined with the angulated ball-rest surface, protects the net attachment knots from abrasion, and also improves ball control during one-handed vertical cradling.

Title: Diaper having a lotioned topsheet
Inventor: WARNER ALRICK VINCENT
IPC: A61Q19/00
Filed: 1995-10-26
Abstract: A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM  to the skin of the wearer, thereby improving the ease of BM cleanup. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

Title: Breast tissue engineering
Inventor: VACANTI JOSEPH P
IPC: C12N5/0793
Filed: 1995-12-15
Abstract: Methods and compositions are described herein for reconstruction or augmentation of breast tissue. Dissociated cells, preferably muscle cells, are implanted in combination with a suitable biodegradable, polymeric matrix to form new tissue. There are two forms of matrices which can be used: a polymeric hydrogel formed of a material such as alginate having cells suspended therein, and a fibrous matrix having an interstitial spacing between about 100 and 300 microns. Preferred polymeric materials are those degrading over about one to two months, such as polylactic acid-glycolic acid copolymers.      The matrices can be seeded prior to implantation or implanted, allowed to vascularize, then seeded with cells. In a preferred embodiment, the cell-matrix structures are implanted in combination with tissue expander devices. As cell-matrix is implanted, or cells proliferate and form new tissue, the expander size is decreased, until it can be removed and the desired reconstruction or augmentation is obtained. The preferred cell types are muscle cells, although other types of mesenchymal cells, fibroblasts, chondrocytes, and adipocytes can be used. Cells obtained from tissue such as the labia can be used for specialized applications such as formation of a nipple type tissue.      Other materials, such as bioactive molecules that enhance vascularization of the implanted tissue and/or which inhibit ingrowth of fibrotic tissue, can be implanted with the matrix to enhance development of more normal tissue.

Title: Data transmission device
Inventor: KAWAHARA TOSHIRO
IPC: H03M13/35
Filed: 1997-06-24
Abstract: A data transmission device comprises a transmitter device and a receiver device. The transmitter device divides a data to be transmitted into an original data requiring protection against code error and a data requiring no protection. The transmitter device then carries out error detection code adding operation and error correction coding at a redundancy 1/N on the original data to generate a coded data. The transmitter device divides the coded data by N, and outputs the N divided coded data and the data requiring no protection on a communication line under a time division multiplexing control. The receiver device receives the N coded data and the data requiring no protection. The receiver device carries out error correction decoding on the N divided coded data and a mixed coded data obtained by mixing the divided coded data, and carries out error detection on decoded data obtained by the decoding. The receiver device then outputs one of the decoded data from which no code error is detected together with the data requiring no protection. The data transmission device can carry out a data transmission protecting the transmitted data from burst code errors and random code errors without increase of redundancy.

Patent CA-2214352-A1 (CA)
Inventor: BOURGAULT PIERRE
IPC: F26B23/10
Filed: 1997-09-02
Abstract: A novel in-bin grain drying system is the subject of the present invention. A boiler having a variable capacity Btu output heats an ethylene glycol/water heating fluid which is circulated through hydronic coils. Fans move ambient air through the hydronic coils and the dry heated air is circulated to the plenum of the grain bin. The air which enters the bin is less moisture laden than in other drying systems, particularly those which are heated by propane flame.      The temperature of the returning fluid is sensed and a fuel supply controller adjusts the amount of fuel supplied to the boiler and thus the Btu output. Accordingly the desired temperature of the air entering the plenum chamber is constant regardless of ambient outside temperature or relative humidity.
