Abstract: A multi-axial bone screw assembly (10) includes a bone screw (11) having a partially spherical head (22). The bone screw head (22) is truncated at an upper surface (24) in which a tool receiving recess (25) is defined. The assembly includes a receiver member (12) including a central bore (34) that defines a tapered recess (35) to receive the head (22) of the bone screw (11). The bore (34) of the receiver member also defines a channel (33) communicating with the recess (35) and configured to receive a spinal rod (R) therein. A portion (37) of the channel is threaded to receive a set screw (14) above the rod. The assembly (10) also includes a crown member (13) disposed between the rod (R) and the head (22) of the bone screw (11). As the set screw (14) is tightened into the receiver member (12), the set screw (14) compresses the rod (R) against the crown member (13), which presses the head (22) of the bone screw (11) into the tapered recess (35). In one embodiment, the head (22) of the bone screw (11) includes a flared edge (26) that penetrates at least the crown member (13) as the assembly (10) is tightened.

Title: Optical transmission system
Inventor: MURAKAMI MAKOTO
IPC: H04B10/2525
Filed: 1999-07-08
Abstract: It is the objective of the present invention to resolve the limitations on transmission capacity and distance in a system by means of a simple design, through the provision of a means for restraining the deterioration in transmission characteristics that is the result of accumulation over the entire system of third order dispersion in the optical fiber. In the present invention, there is provided an optical fiber transmission path in which positive dispersion fibers 40,46,52,and 54 and negative dispersion fibers 42,48 (referred to as optical fibers hereinafter), which have at least second and third order dispersion of mutually opposite signs, are combined. In addition, the optical fiber is disposed so that the average third order dispersion value on the transmission path overall is reduced, and so the length of each optical fiber is sufficiently smaller than the square root of the product of the second order dispersion length, which is determined from the second order dispersion value of the optical fiber and the pulse width of the signal, and the non-linear length, which is determined from the average power of the signal within the optical fiber and the optical fiber nonlinear coefficient.

Patent CA-2289643-A1 (CA)
Title: Production of methanol
Inventor: ABBOTT PETER EDWARD JAMES
IPC: C07B61/00
Filed: 1998-06-08
Abstract: A process for the production of methanol comprises converting a hydrocarbon feedstock at a pressure above the desired synthesis pressure into a synthesis gas mixture containing hydrogen, carbon oxides and steam at an elevated temperature and pressure, cooling said mixture to condense water from the mixture, separating the condensed water, and passing the resultant gas mixture, with no further compression and no recycle of unreacted gas, at an elevated temperature through a series of at least two methanol synthesis stages with separation of synthesised methanol from the gas mixture after each stage. The hydrocarbon feedstock is converted into the synthesis gas mixture by a catalytic steam reforming process wherein the heat required for reforming is supplied by the products of combustion of the unreacted gas remaining after separation of synthesised methanol, and, preferably also by the reformed gas after it has left the reforming catalyst.
Patent CA-2290836-A1 (CA)
Title: Integrally moulded plastic landscape edging strip and spikes
Inventor: GIBSON SIDNEY
IPC: A01G9/28
Filed: 1999-11-25
Abstract: The invention relates to a moulded plastic landscape edging strip with integrally moulded plastic spikes that can be severed on site for use in installation and also serve during storage and handling to stiffen the rear edge of the flexible plastic edging strip. Plastic spikes are less expensive to manufacture than conventionally used galvanised steel spikes, however, when integrally moulded with the plastic edging, the marginal increase in cost of the spikes is very low. The costs and time involved in manufacturing, inventory maintenance, handling, shipping and installation are reduced as a result of integrally moulding the spikes and edging together.The edging strip has an elongate vertical wall with bottom edge, front and rear faces, a horizontal footing extending rearwardly from the bottom edge with longitudinally spaced apart apertures and elongate plastic spikes severably joined to the rearward end of the footing. The spikes have a cross-sectional profile adapted for vertical insertion through the apertures, and may include serrated edges to inhibit withdrawal after installation. The integral moulding of spikes with the edging relieves the installer and distributor from the burden of stocking and purchasing separate spikes, calculating the number of spikes necessary for installation, and eliminates the risk of misplacing spikes or forgetting to bring spikes to the job site. The integral moulding of spikes also ensures that edging and spike materials are compatible and will not corrode.
