Abstract: An improved aircraft tire 10 is described.  The tire 10 has at least one circumferentially extending reinforcement inserts.  At least one reinforcement inserts 90 is located on one side of the tire.  Each insert 90 preferably has two cord reinforced members 91,92 having bias angled cords.  The cords are equal but opposite in orientation relative to the cords of the adjacent member.  The pairs of reinforced members 91,92 extend from the bead portion 18,20 and terminate in a radially upper portion of the sidewall 14A,16A. Each pair of reinforcement members 91,92 is interposed between the carcass plies 36,37,38,39,40,41, and the sidewall of the tire 10.  This structure can increase tire durability while at the same time achieve a significant weight reduction.  In a preferred embodiment of the invention the inserts 90 are located on only one side of the tire, this asymmetric construction prevents tire damage from an arrestor cable used on aircraft carriers.  Alternatively the inserts can be symmetrically added to each side of the tire

Patent CA-2154606-A1 (CA)
Title: Method and apparatus for nozzle mix gunning
Inventor: WIRTH EMIL J JR
IPC: B05B7/04
Filed: 1995-07-25
Abstract: A method and apparatus for thoroughly mixing a flow of particulate gunning material suspended within a gas with a regulated liquid flow and thereafter directing the wetted material through a nozzle toward a substrate a distance removed from the apparatus.  The apparatus utilizes a water injection ring for mixing the liquid and particulate streams. The ring comprises a substantially circular member having an inner surface, an outer surface, a first end and a second end. The inner surface defines a substantially open bore extending from the first end to the second end.  The circular member is further provided with liquid injection apertures, each having an inlet on the outer surface and an outlet end on the inner surface.  The inner surface has a first diameter at the first end thereof and a portion operatively associated with the outlets of the injection apertures to produce a region of reduced static pressure adjacent the aperture outlets within the bore.  The portion of the bore which is operatively associated with the outlets has a second diameter greater than the first diameter and is located between the first and second ends of the bore.  The combined effect of a regulated liquid flow to and through the water injection ring with the reduction in static pressure thus obtained by the geometry of the ring bore ensures that the particulate is thoroughly mixed with the water.

Title: High efficiency translation of mrna molecules
Inventor: ANDREWS DAVID W
IPC: C12N15/67
Filed: 1996-02-12
Abstract: An increased level of translation of a selected mRNA molecule is effected by coupling specific nucleotide sequences at the 5'- and 3'  -ends of a nucleic acid molecule transcribable to or which itself is the mRNA molecule.   The nucleotide sequence at the 5'-end is effective to increase the rate of translation initiation of the mRNA molecule in a cell while the nucleotide sequence at the 3'-end is effective to increase the period of translation of the mRNA molecule in a cell. The nucleotide sequence of the 3'-end is provided by a 3'-untranslated region (3'-UTR) of a gene, particularly that of .beta.-prolactin, or an effective fragment thereof. A polyadenylation sequence preferably is provided at the 3'-end of the 3'-UTR sequence.   The 3'-UTR sequence provides mRNA stabilization independent of the poly A tail.
