Patent CA-2129685-C (CA)
Inventor: KEITH PETER G

Abstract: A method of connecting a tow vehicle to a trailer having a front axle assembly which pivots about a vertical axis. The method includes the following steps which will be hereinafter described. Firstly, position a drawbar assembly between the tow vehicle and the trailer. The drawbar assembly has a tow vehicle end and a trailer end. The tow vehicle end is mounted to a single articulation point at a rear of the tow vehicle.      The trailer end is pivotally mounted on a substantially horizontal transverse axis thereby accommodating up and down movement while precluding side to side movement of the drawbar assembly. Secondly, position a steering arm assembly between the tow vehicle and the front axle assembly of the trailer.      The steering arm assembly includes a pair of steering arms having tow vehicle ends and trailer ends. The tow vehicle ends are adapted for omni-directional attachment to the tow vehicle equidistant from the single articulation point. The trailer ends are adapted for omni-directional attachment to the front axle assembly of the trailer equidistant from the vertical pivot axis of the front axle assembly, thereby accommodating relative movement of the tow vehicle and the front axle assembly of the trailer while causing a proportianate change in the angular positioning of the front axle assembly of the trailer to maintain correct steering geometry of the trailer relative to the tow vehicle as the tow vehicle turns.

Granted: 2000-02-01
Abstract: Improved organophilic clay gellants for highly viscous systems such as asphalt and creosote can be prepared by a process wherein the smectite-type clay is gently dried and/or subjected to minimum or no grinding. The organophilic clay agent may be used to thicken a variety of organic compositions including pitch and heavy resins. In a preferred aspect, the organophilic clay gellant can be directly added to asphalt systems in order to efficiently and effectively modify the viscosity thereof without the use of either a polar activator as a dispersion agent or a preactivation agent.

Granted: 2001-08-07
Abstract: There is provide a method for optical telecommunications with which an optical signal modulated for the plane of polarization can be received for certain without lowering the threshold level and being affected by noises so that any optical telecommunications can be identified without fail. With the method, an optical signal is modulated by continuous pulses a at the transmitting side before transmission and a predetermined number (n) of pulses a are extracted within a given period of time in synchronism at the receiving side so that the presence of a modulated optical signal is acknowledged only when the number of pulses a received within the given period of time is smaller than the predetermined number (n) but greater than another predetermined number (m) (n  m). This method may be so modified that the absence of a modulated optical signal is acknowledged even when the above defined numberof pulses are received if k or more than k (k  1) noise signals b are found between any successive two of the received pulses.

Abstract: A cordless telephone system includes an arrangement wherein multiple portable units operate with a common base unit using the same security code without conflict or confusion. When a portable unit attempts to establish a radio link with the base unit, for example, this originating portable unit generates a random number which is retained by this unit and also transmitted  to the base unit. This random number is substituted for the common stored security code, then shared by the base unit and all of the portable units, for creating a temporary unique security code that is known only to the base unit and the originating portable unit. Interference from other portable units attempting  to gain access to the base unit while the originating portable unit is actively communicating with the base unit is thereby advantageously prevented.

Granted: 2004-03-30
Abstract: A footwear system for providing enhanced protection and comfort to the foot of a wearer by reducing impact and shearing forces normally received by the foot. The footwear system has a knit sock and a shoe. The knit sock overlies and contacts the shoe and includes a ball portion, a heel portion, and an arch portion disposed between the ball and heel portions.      Each of the ball and heel portions is formed of thicker knit fabric than the arch portion thereby providing a greater amount of protection and cushioning to the ball and heel of the foot of the wearer than to the arch portion. The shoe includes a sole having a ball portion, a heel portion, and a raised arch portion for contacting and interfacing with the respective overlying portions of the sock. The raised arch portion of the sole preferably corresponds substantially to the lengthwise extent of the thinner fabric arch portion of the sock when positioned on the foot of a wearer so as to provide a substantially mating interfacing relationship for added protection and comfort to the wearer thereof.

Granted: 1998-12-22
Abstract: A composite insulator-producing compression mold device is formed of a pair of molding units each having a recess for the formation of a housing of a composite insulator.  At least one partition plate is fitted to one of the molding units near the composite insulator housing-forming recess and at a location radially outwardly from said recess.          An urging member is provided for urging the partition plate toward the other molding unit such that an outer end portion of the partition plate may project toward the other molding unit from a parting face of the one molding unit when the molding units are opened, whereas when the molding units are closed, the partition plate may be received within the one molding unit.  The partition plate is prevented from being detached from the one molding unit.  As a pair of the molding units are to be closed, the outer end portion of the partition plate is brought into contact with a mold-parting face of the other molding unit by the urging means and thereby insulating material fed into said recess for the formation of the housing is prevented from flowing radially outwardly through between the parting faces.

Abstract: A communication network (I) comprises a number of network nodes (2. 3, 4 and 5) linked together by transmission paths (6, 7 and 8). A network manager (9) controls acceptance of calls onto transmission paths by classifying an incoming call and selecting from the database (14) an appropriate mean to peak bit rate distribution, This selected distribution is then used with the monitored transmission path load to determine a posterior distribution which reflects the load. The decision to accept or reject the call is made on the basis of the posterior distribution by a call acceptance algorithm considering the effective bandwidth for example.

Title: Ink cartridge and a method for sealing an aperture provided for such cartridge
Inventor: KAMIYAMA YUJI
IPC: B41J2/175
Filed: 1996-09-27
Granted: 2001-03-06
Abstract: An ink cartridge for ink jet use is provided with an aperture for filling in the cartridge with ink.  The circumference of the aperture and a part of a plug pressed in the aperture are fused and welded to be formed integrally to airtightly close the aperture, and obtain an integrated structure without any interface.          Hence, it is made possible to reliably prevent ink from leaking therefrom, even if some scratches and cracks are present on both of them. This contributes to eliminating inspection steps to find ink leakage in the course of manufacture, and also, contributes to improving the yield of production. As a result, a significant reduction of costs is possible, while enhancing the reliability of the ink cartridge.
