Patent CA-2179558-A1 (CA)
Inventor: VERMEER ARTHUR A
IPC: E04B7/16
Filed: 1996-06-20
Abstract: A greenhouse roof structure for the usual rectangular in plan greenhouse comprises at least two rectangular roof panels each having a lower edge hinged to the structure for movement about a respective horizontal hinge axis.   The roof panels are movable about their hinge axes between a fully closed position in which their upper edges meet to form a roof peak, and a fully open position in which they extend generally vertically at least approximately parallel to one another for the greenhouse space to be upwardly fully open to the ambient atmosphere, as is needed for example to "harden" new plants before they are exposed to the harsher ambient conditions outside the greenhouse.          Preferably trusses extend transversely between the two outer side walls, support members are carried by the trusses, and transversely extending upwardly convex arch members are each connected at its ends to respective support members to connect them against the forces, such as wind forces, applied by the roof panels.   A ridge post member for each arch member extends vertically from its transverse centre point and a ridge member is mounted on the ridge post members.          Preferably the roof panels are pivotally mounted on the arch members closely adjacent to the support members.

Title: Steering wheel overlay
Inventor: POTEET TOM A
IPC: B62D1/06
Filed: 1997-03-24
Abstract: A steering wheel "after-market" overlay, having a unitary, integral, relatively stiff, thin-walled construction, is adapted to be adhesively applied to and closely conform to the surface of the upper portion of an original equipment steering wheel. The overlay covers not only the upper portion of the steering wheel grip but also the upper portions of the steering wheel spokes up to the center pad of the steering wheel. The portion of the overlay covering each spoke has an radially inner terminus including a flange that is adapted to extend into the small space that typically exists between the inner end surface of the spoke and the side peripheral surface of the center pad. By also covering the upper portions of the spokes, not only is the appearance of the overlaid steering wheel enhanced, but the bonded surface area is substantially increased thereby assuring the long term positional stability and peel resistance of the overlay.

Title: Method of manufacturing lithium sulfide
Inventor: YAMAMOTO KAZUTOMI
IPC: C01B17/22
Filed: 1997-04-14
Abstract: Lithium sulfide can be manufactured by the reaction between lithium hydroxide  and gaseous sulfur at the temperature of 130 to 445 °C.  As lithium hydroxide is solid and raw material as sulfur is gas at this temperature, fluidization and mechanical agitation are effective to react solid with gas.  It is important to control lithium hydroxide's size in order to react two components smoothly and  perfectly.

Title: Process and apparatus for homogeneous charging of solid catalyst particles in a tubular reactor
Inventor: TREF JEAN-PIERRE
IPC: B01J8/06
Filed: 1997-04-25
Abstract: Homogenous charging of particles of solid catalyst (6) into a tubular reactor containing vertical tubes (2) opening at their top through a perpendicular tube plate (3) which reunites them, uses a charging system which ensures a homogenous rain of particles onto the whole surface of the plate. Around the periphery of the plate a first cylindrical wall (11) with a diameter similar to that of the plate is placed so all the charging orifices of the tubes are inside. The particles are charged homogenously within this cylinder until the tubes at the perimeter of the tube plate and near the cylindrical wall are full. A second cylindrical wall with a smaller diameter is placed on the tube plate so the tubes which are full are outside the second wall and those which are not are inside it. The homogenous distribution is restarted until the tubes nearest the second cylinder are full, and the cycle is repeated with diminishing diameter cylinders each time separating the full tubes from those which are not. Also claimed is a device to carry out the above process using a series of cylindrical walls of diminishing diameters to fill the tubes successively from periphery to centre.

Patent CA-2218645-A1 (CA)
Inventor: PARR MICHAEL J
IPC: B44C3/04
Filed: 1997-10-20
Abstract: A method for making a decorative particulate material in which a clay based cat litter or other suitable particulate material is tumbled in a rotating barrel, sprayed with paint, and while the paint is wet, powdered mica is dispersed over the mixture. The adhesive paint adheres the mica to the particulates. Since only a single layer of mica adheres, the mica is used very efficiently. A clear gelatine-based top coat is sprayed over the mica. The finished particulates of mesh size 30 to 3 mesh, can be used in glass containers as a candle base and serve to contain liquid wax from the burning candle, preventing the wax from contacting the container walls. The resultant clump of wax and particles can easily be removed and thrown out.

Abstract: A catheter and introducer needle assembly is provided wherein the catheter includes a side port and a plug located in the catheter hub, the needle is notched and is securely mounted to a shield housing with a plurality of telescoped tubesconcentrically surrounding the needle. One of the telescoped tubes is securely connected to the shield housing.  The other tubes in the assembly may be slid with respect to one another and distally away from the shield housing.  The tubes have combined lengths to enable complete shielding of the needle when the tubes are telescopingly extended. The tubes include interlocking mechanisms to prevent separation of the tubes and to prevent collapse of the tubes once they have beenfully extended. The distal-most tube, when the tubes are telescopingly extended,engages a catheter hub to prevent withdrawal of the needle from the shield assembly until the tubes are fully telescopingly extended. After the needle is fully shielded, the shielded needle is separated from the catheter hub.

Title: Intubation system having an axially moveable memory cylinder
Inventor: RAYBURN ROBERT L
IPC: A61B1/005
Filed: 1997-12-23
Abstract: An intubator includes a housing and a memory cylinder connected for axial movement relative to the housing.  A flexible scope tube attached to the housing extends within and through the memory cylinder such that the scope tube can be retracted within or caused to extend beyond the distal end of the memory cylinder by the relative axial movement between the housing and memory cylinder.  The scope tube is angularly adjustable and includes a light transmitting  fiber  optic  cable,  a  visual  transmission fiberoptic  cable,  and  a  fluid  conduit.    In  use,  an endotracheal tube is mounted on the memory cylinder such that the endotracheal tube, memory cylinder and scope tube have their distal  ends  flush.   The  intubator is  then inserted through the patient's mouth to the larynx opening. Collapsing the memory cylinder within the handle causes the scope tube to be extended from the memory cylinder for positioning within the trachea.  The endotracheal tube can then be located within the trachea using the scope tube as a stylet or guide.
