Patent CA-2051569-A1 (CA)
IPC: G03G15/00
Filed: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE   A simplified low cost, low wear, sheet registration and feeding system for laterally (side) registering a sheet without frictional drive slippage against the sheet and while maintaining feeding control in the primary forward feeding direction of the sheet. The sheet may be fed both forward and laterally (towards a side guide edge for side registration) utilizing only multiple sheet-engaging rotatable ellipsoidal rollers angularly mounted around the periphery of a fixed angle rotating hub member. The sheet-engaging rollers rotate with the hub member to so feed the sheet, but are also rotatable about their own, different, axes of rotation, which axes are parallel to the forward feeding direction of the sheet and the side guide to allow the sheet-engaging rollers to roll after side registration is achieved to prevent excessive lateral feeding force and undesirable slippage, smearing and/or wear.

Filed: 1991-09-24
Abstract: The invention provides a molten metal producing and refining method which does not damage the apparatus, realizes a stable and high second combustion rate, and is capable of effectively recovering heat generated by the second combustion. It is a molten metal producing and refining method wherein a metal-containing material, a carbonaceous material, a flux and O<6> gas are introduced into a furnace, the carbon dissolving into the metal bath in the furnace from the carbonaceous material is combusted with the O<6> gas to generate heat and CO gas, the CO gas is subjected to the second combustion with the O<6> gas to additionally generate heat, and the metal-containing material is melted and refined by both the generated heat and carbon, said method being characterized in that O<6> gas or O<6>-containing gas is blown into the furnace through large-diameter tuyeres installed near the bottom of the furnace and a part of the O<6> gas does not combust in the metal bath and leaves the metal bath unburnt, to perform the second combustion of the unburnt O<6> gas with CO gas in the slag bath in the furnace. <IMAGE>

Abstract: An improved pipe jointing system includes sections of pipe having annular grooves about each of the ends thereof and a coupling having a rigid outer layer and an elastomeric inner layer fixedly secured thereto.  The inner layer has a inwardly directed lip and a pair of opposing sets of sawtooth ridges, one set disposed on each side of the lip.  A pair of the pipes inserted into opposing ends of one of the couplings in end-to-end relationship compresses the respective lip therebetween forming a fluid-tight seal between the coupling and the pipes.  The grooves are adapted to receive respective ones of the sawtooth ridges such that axial movement of the pipes relative to the coupling is resisted.   A modified embodiment provides a pipe and coupling system whereby an elastomeric inner layer of the coupling creates sufficient frictional force to resist axially outward movement of the pipes relative to the coupling.

Abstract: Dans un procédé et un dispositif pour l'insertion automatique de mandrins dans des machines à découper à roulettes du type à cylindre d'appui, une large bande (12) de papier ou similaire est déroulée d'un large rouleau (11) au niveau d'un poste de débobinage (10). Dans un poste de découpage (20), cette large bande (12) est divisée dans le sens la longueur en au moins deux bandes partielles (24) plus étroites. Dans deux postes de bobinage (40, 50) disposés chacun sur un côté du ou des cylindres d'appui (30) et constitués chacun d'au moins un enrouleur (41, 51), les bandes partielles (24) plus étroites sont enroulées avec utilisation de mandrins (44, 54) de telle manière que chaque bande partielle (24) voisine soit enroulée sur des postes de bobinage (40 ou 50) différents. Dans un dispositif d'insertion (60), les mandrins (44, 54) sont glissés successivement, en fonction des enrouleurs (41, 51) à équiper, dans une position de réception parallèle au cylindre d'appui (30) ou aux cylindres d'appui, répartis des deux côtés du ou des cylindres d'appui depuis leur position de réception et transportés dans une position de tension des enrouleurs (41, 51) pour y être tendus afin de recevoir ensuite la bande partielle correspondante. Les mandrins (44, 54) se trouvant dans leur position de réception et répartis des deux côtés du ou des cylindres d'appui sont repris par le dispositif de transport (70) associé à chaque enrouleur (41, 51) et soulevés ou abaissés en position de tension suivant un parcours essentiellement rectiligne. De cette manière, l'insertion automatique des mandrins est sensiblement améliorée, étant donné que le recours à des dispositifs mécaniques est relativement faible, en dépit d'une suppression d'importants travaux d'ajustage, d'une réduction des temps de préparation et d'une économie de personnel d'entretien.

Title: Load measuring apparatus for an elevator car
Inventor: PEARSON DAVID B
IPC: G01G19/18
Filed: 1992-11-30
Abstract: P10377.S01 Abstract of the Disclosure The load measuring apparatus is arranged at an elevator car and detects the car load brought about by passengers and/or goods transported by the elevator car.   An upper crossbeam together with vertically extending supports and a lower crossbeam forms a support frame suspended at traction cables and moves within an elevator shaft along suitable guide rails.  A floor frame mounted on isolation pads at the lower crossbeam carries the elevator car.   At the roof of the elevator car there is centrally arranged a reference plate member which is part of the load measuring apparatus.   A proximity sensor centrally arranged at the upper crossbeam has a predetermined frontal  spacing from the  reference plate member in the no-load condition of the elevator car.  When the elevator car carries a load this predetermine frontal spacing increases as a function of compression of the isolation pads. The proximity sensor then generates an electrical signal or potential which is dependent upon the momentarily prevailing frontal spacing from the reference plate member.

Abstract: An Acquired Immunodeficiency Syndrome (AIDS) vaccine containing the Human Immunodeficiency Virus, Type-1 (HIV-1) envelope proteins is produced from cloned HIV-1 envelope genes in a baculovirus-insect cell vector system. The recombinant HIV-1 proteins are purified, assembled into particles and then adsorbed on an aluminum phosphate adjuvant. The resulting adsorbed recombinant HIV-1 virus envelope protein formulation (AIDS vaccine) is highly immunogenic in animals and elicits antibodies which bind to the HIV-1 virus envelope and neutralize the infectivity of the virus in in vitro) tests. The above AIDS vaccine induces new humoral and cellular immune responses in HIV-infected patients and is useful as a form of vaccine therapy to delay or prevent the destruction of the immune system.
