Title: Protective helmet and method of making same
Inventor: FERGUSON MARK
IPC: B29C37/02
Filed: 2002-02-27
Abstract: A protective helmet (10) includes: a shell (12), a headband (13) with an absorbent brow pad (11), and a suspension (14). A key (18a, 18b, 18c, 18d) i s secured to each end of each of the straps (16a, 16b) of the suspension (14) for insertion into respective key sockets (20a, 20b, 20c, 20d) spaced about the periphery of the shell (12) of the protective helmet (10) along its lowe r edge. Of particular importance to the protective helmet (10) of the present invention, many (if not all) of the keys (18a, 18b, 18c, 18d) are molded directly to and around a strap (16a, 16b), rather than sewn to the strap (16 a, 16b). In the method of the present invention, lengths of strap material are positioned in a mold (32), and plastic is injected into the mold cavity (32a ) to encapsulate the straps (116a, 116b, 116c) and form the plastic component, e.g., a key (18) for the suspension of the protective helmet (10). A trimmin g die is used to trim any webbing scrap between parts or other extraneous materials resulting from the molding of the plastic component to the straps (116a, 116b, 116c).
Patent CA-2437616-A1 (CA)
Inventor: SAIN MOHINI M
IPC: C08H8/00
Filed: 2003-08-04
Abstract: Natural grown fibers are gaining a renewed interest, especially as a glass fiber substitute, partly due to ecological concerns. Natural fibers like hemp, flax, sisal, and jute;  Agro-based fibres such as Bagasse, wheat straw etc and root crops like Rutabaga fibers hold potential for such innovations due to their availability and low cost. These natural fibers are bundles of individual strands of fibers held together by means of interface of pectin and lignin.  Apart from the long fibers there are fibers, which are on much smaller scale and have 5-50 nm diameters and are thousands of manometer long. The objective is to isolate these nano-sized microfibrils, which are embedded in hydrated, amorphous matrix of hemicelluloses and pectin.  Chemical treatment is done to remove the impurities like hemicelluloses and extractives since higher cellulose content in the fibre leads to higher strength and stiffness of the fibre and then individualization of the cellulose microfibrils done by using mechanical shear force with the help of cryocrushing and high-pressure defibrillization. These namo-sized microfibrils[also referred as namo-fibrils] could contribute towards producing composite materials of very high strength at a low cost in an environmentally friendly manner suitable for biocompatible medical devices, packaging and other high strength structural applications.

Title: N4 virion single-stranded dna dependent rna polymerase
Inventor: KAZMIERCZAK KRYSTYNA M
IPC: C12N9/10
Filed: 2002-05-22
Abstract: A histidine-tagged, deletion mutant of bacteriophage N4-coded, virion RNA  polymerase (mini-vRNAP) which is active has been developed. The his-tagged mini-vRNAP has been cloned under the control of the Pbad promoter, is stable and is purified in a single step yielding large amounts (10 mg/liter of E.  coli expressing cells). This RNA polymerase uses single-stranded DNA  containing 17 bases (the promoter) upstream of the transcribed regions as a template. In the presence of E. coli SSB protein, it transcribes this template efficiently, providing a unique system to synthesize RNAs of the desired sequence using single-stranded DNA templates. The enzyme incorporates derivatized nucleoside triphosphates with high efficiency. A mutant of mini-vRNAP has been generated that incorporates deoxynucleoside triphosphates. In addition, the inventors have developed an in vivo system to express RNAs and proteins under mini vRNA polymerase promoter control.

Inventor: HWANG CHARLES G
IPC: A61M5/32
Filed: 2002-06-27
Abstract: A needle shield (26) and needle shield assembly (20) are provided for preventing accidental needle sticks. The needle shield (26) includes opposin g sidewalls and is pivotable between an open position that allows use of the needle cannula (30) and a closed position that covers at least the tip of th e needle cannula (30).
