Patent CA-2297296-C (CA)
Title: Multi-dump metering valve
Inventor: BROOKE PETER LEIGHTON
IPC: A62C3/02
Filed: 2000-01-27
Granted: 2005-04-12
Abstract: In one aspect, the invention is directed towards a helicopter-carried firefighting device including a valve. The valve has an outer assembly and an inner assembly in which the outer assembly has a reduced surface area on those surfaces which are disposed normally to a direction of movement. The outer assembly therefore may be less affected by hydrostatic and hydrodynamic forces directed so as to oppose its movement. The valve may be located in a reservoir of fluid, and controlled by a control head operated remotely from the helicopter so as to release fluid from the reservoir over a fire. The valve may be symmetrical about a longitudinal axis of the valve, such that transversely directed fluid flows through the valve may be cancelled, producing a coherent, longitudinal fluid flow. The valve may be opened partially so as to operate as a metering valve. The valve may be closed relatively rapidly to retain fluid in the reservoir so as to permit multiple dumps from a single reservoir if so desired.

Abstract: A novel electrical connection device for surface-mounting on a circuit board. The electrical connection device includes at least two terminal members. Each terminal member includes a retaining surface serving as a point of electrical contact between the terminal member and the circuit board and as a point of solder-anchoring for securely mounting the electrical connection device to the PCB. Further, each terminal member includes a contact portion providing for the mounting of an electrical component onto the circuit board, as well as serving as a point of electrical contact between the circuit board and the electrical component. The terminal members are mounted on a strip of insulating material that holds them in the proper spacial relationship until they have been secured to the circuit board. The strip reduces pin-misalignment that can cause difficulties in engaging a mating electrical component on the electrical connection device. Optionally, the strip can be removed from the pins once the pins are fixed on the circuit board.

Title: Liquid acidic limescale removal compositions packaged in a spray-type dispenser
Inventor: DELUCCA BARBARA
IPC: C11D3/02
Filed: 1998-11-02
Granted: 2005-07-26
Abstract: The present invention relates to liquid acidic compositions suitable for removing limescale-containing stains from a hard-surface, comprising an acid, from 0.001 ~o to 20 % by weight of the total composition of a polysaccharide polymer and from 0.001 % to 20 % by weight of the total composition of a vinylpyrrolidone homopolymer or copolymer, said composition being packaged in a spray type-dispenser. Such a composition provides improved shine to the surface treated while exhibiting effective limescale removal performance. The use of a polysaccharide polymer and a vinylpyrrolidone homopolymer or copolymer, in a liquid acidic composition being packaged in a spray-type dispenser, to treat a hard-surface, reduces or even prevents the formation of watermarks and even limescale deposits on said hard-surface after said hard-surface has first been treated with said composition and subsequently comes in contact with water. Also the use of a polysaccharide polymer and a vinylpyrrolidone homopolymer or copolymer, in a liquid acidic composition being packaged in a spray-type dispenser, to treat a hard-surface delivers shine/long lasting shine to the surface.

Title: Paper machine, paper machine belt for and method of manufacturing textured soft paper
Inventor: POLAT OSMAN
IPC: D21H27/00
Filed: 1998-12-16
Granted: 2007-07-17
Abstract: A paper machine for manufacturing textured soft paper comprises a press section with a press nip, through which an impermeable belt and a felt run with the fibrous web between them, a drying cylinder and a transfer roll forming a nip for transfer of the web to the drying cylinder. Smooth impermeable belts ride less of the web over longer distances, and do not facilitate web transfer to a smooth roll. The impermeable belt is a texturing belt with a web-contacting layer having depressions and surface portions forming a relief pattern in the web, the texturing belt running from the press to the drying cylinder carrying the textured web to the transfer nip. The felt runs away from the texturing belt before a water film formed in the press nip breaks up. Adhesive is applied on the drying cylinder before the transferring.

Abstract: Nonsymbiotic hemoglobins are broadly present across evolution; however, the function of these proteins is unknown. Cultured maize cells have been transformed to constitutively express a barley hemoglobin gene in either the sense (HB+) or antisense (HB-) orientation.  Hemoglobin protein in the transformed cell lines was correspondingly higher or lower than in wild type cells under normal atmospheric conditions. Limiting oxygen availability, by placing the cells in a nitrogen atmosphere for 12 hours, had little effect on the energy status of cells constitutively expressing hemoglobin, but had a pronounced effect on both wild type and HB- cells, where ATP levels declined by 27 % and 61 % respectively. Energy charge was relatively unaffected by the treatment in HB+ and wild type cells, but was reduced from 0.91 to 0.73 in HB- cells suggesting that the latter were incapable of maintaining their energy status under the low oxygen regime. Similar results were observed with P. aeruginosa cells transformed with an Hb expression vector. It is suggested that nonsymbiotic hemoglobins act to maintain the energy status of cells in low oxygen environments and that they accomplish this effect by promoting glycolytic flux through NADH oxidation, resulting in increased substrate level phosphorylation. Nonsymbiotic hemoglobins are likely ancestors of an early form of hemoglobin that sequestered oxygen in low oxygen environments, providing a source of oxygen to oxidize NADH to provide ATP  for cell growth and development. This in turn suggests that cells containing increased levels of Hb protein will survive longer under low oxygen tension or high energy demand.

Abstract: A system for roofing a substructure his a plurality of roof panels, a plurality of support members and a plurality of cap members. The roof panels each have a horizontal channel section bounded on a pair of opposing side edges by side flanges, with an upper end of each side flange bent to provide a groove opening outwardly laterally from the panel. The support members each have a pair of oppositely extending base flanges and a pair of oppositely extending top flanges, the base flanges and top flanges being positioned along a vertical web member. The top flanges are adapted to be received in the groove of one of a pair of adjacent roof panels and one of the base flanges of each support member is adapted to fasten the support member to the substructure. The cap members have side walls to retain the top flanges in the grooves without fastening the roof panel to the support member, thereby allowing some relative movement upon deflection of the roof panel. The length of the support members allows a single support member to be fastened to each of a pair of spaced-apart substructural members, such as purlins.
