Patent CA-2266991-A1 (CA)
Inventor: WHITE KEVIN T
IPC: G02B6/44
Filed: 1999-03-26
Abstract: Water blocking components (31, 35, 51, 55) for blocking the flow of water in fiber optic cables (10, 40, 70) and methods of making the components. Each water blocking component (31, 35, 51, 55) includes a respective plastic substrate (32, 36, 52, 55) that includes a water absorbent entity, for example, a water absorbent layer (60). The water absorbent layer is a mixture of a water absorbent substance and an adhesive substance. The cross sectional profiles of water blocking components (31, 35, 51, 55) permit a distribution of the water absorbent substance, and the adhesive substance stabilizes the position of the water absorbent substance, thereby advantageously establishing the water blocking effectiveness of components (31, 35, 51, 55).      Additionally, the bulk of the substrates themselves substantially fill the grooves and thereby effectuate a water blocking function. A method of making water blocking components (31, 35, 51, 55) includes the application of water absorbent layer (60) as a thin surface treatment, i.e., it is not impregnated into the substrates but, rather, it is adhered to the smooth, non-porous surfaces of the substrates. Substrates (32, 36, 52, 55) may be in the form of foamed rods. Figures 1-2.

Abstract: Apparatus and methodology for radio utility meter reading processing of data acquisition for use with an automatic billing system involves a utility meter transmitter antenna system installed at or near ground level. An RF utility meter communication apparatus transmits utility meter data to a remote utility meter data collection unit from an underground pit box. The pit box includes a utility meter and has a generally ground level pit lid with an opening therethrough. An antenna element has an upper member extending at least partly through such pit lid opening. A depending base of the antenna element extends from the upper element and passes through the pit lid opening into the underground pit box. The depending antenna element is capacitively coupled or provided with some other form of non-mechanical coupling to the output of an RF transmitter also included within the pit box. The antenna element components are nested for ease of attachment to or removal from a pit lid, with a rotatable threaded nut received about a depending antenna element for drawing tight against the underside of the pit lid, with an upper antenna element received above such pit lid. An antenna element may be directly coupled with a metallic pit lid so that such metallic pit lid functions as part of the antenna. Alternative embodiments may be provided for structure of the antenna element, so as to minimize the structure and components needed for removably securing or installing the antenna arrangement, supported on the removable pit lit of a conventional pit box.

Abstract: The present invention involves a system and method for enabling transfer of title in property (TIP) wherein the property is usually money, between a Source and a Destination according to the terms defined by parties to an agreement. The Destination sends the agreement specifications to the Central Controller (CC) for authorization. Once the CC authenticates the agreement, the CC initiates transfer in the TIP as per the terms during one or more transfers from a Source TIP to a collection trust. As the defined targets are reached in the collection trust, a portion of its contents is transferred to the Destination TIP. The system can be used to transfer TIP for property as diverse as real property, money, shares, other choses in action, wherein applications can range, for example, from transfer of regular payments from a paycheck to: service providers, goods providers, alimony payments, non-profit organizations, etc. The system may also be used by individuals or companies to transfer incremental ownership in land or shares in a company.

Filed: 2000-02-24
Abstract: A chair control mechanism for a chair assembly having a seat and a back includes an arrangement for mounting the lower end of a back support member, for positioning the back above the seat. The chair control mechanism includes a variable configuration mounting area so as to enable different back support members to be used with the same basic chair control mechanism structure. In one version, the variable configuration mounting area is provided by engaging one of a series of inserts within a transverse rear wall defined by the chair control mechanism. Each insert defines a passage configured to receive the lower seat mounting section of a back mounting member having a different set of dimensions, and the seat mounting section of the back mounting member extends through the passage and is engaged with the chair control mechanism by means of a fixed fastener-type arrangement or by a hand screw received within a slot for providing adjustability in the position of the back relative to the seat. In another version, the chair control mechanism includes an upper wall and a pair of depending sidewalls, with inwardly extending protrusions formed on the sidewalk which cooperate with the upper wall and sidewalls to define a space for receiving a seat mounting section having a maximum set of dimensions. Inserts are engageable with the protrusions for altering the effective dimensions of the space so as to enable seat mounting sections of different, smaller dimensions to be received between the sidewalls, top wall and protrusions.

Title: Method for rubberizing and/or pelletizing trinidad lake asphalt
Inventor: NICHOLAS DOLLY
IPC: E01C19/10
Filed: 1998-10-07
Abstract: Method of processing Trinidad Lake Asphalt (TLA), including the steps of removing Trinidad Lake Asphalt from the earth and adding thereto at least one stabilizing material of a type which increases the melting point of the TLA to produce a stabilized product. The stabilizing material is preferably clay, carbonaceous material, silica and/or polymer. The stabilized product is then pulverized or otherwise broken down into discrete elements, such as pellets or powder. The discrete elements are then packaged into, for example, polyethylene bags and stored or transported for later use. The stabilizer prevents the discrete elements from coalescing during storage or transport.  The bags of discrete TLA elements may be used to improve road building mixes by throwing the entire bag, including the bag itself, if desired, into a mixer with the other road building materials. A method is also disclosed for increasing the surface tension of the TLA in order to make the TLA more user friendly.

Title: Power control circuit for the heating element of an electrophotographic device
Inventor: DRAGOJEVIC MILAN
IPC: H02M5/293
Filed: 2000-06-14
Abstract: Power control circuitry for regulating power to the heating element of an electrophotographic copier or printer. The circuitry uses a low pass filter to filter an AC power source and employs a PWM control technique to periodically apply the filtered AC power through a bi-directional AC switch to the heating element. Snubbing circuitry periodically dissipates the energy accumulated in the parasitic inductance of the heating element. The parasitic energy is dissipated through a resistance that varies depending on the amount of energy stored in the parasitic inductance. This minimizes the power loss attributable to the snubbers. The circuitry also limits EMI and harmonic currents to tolerable levels, and enables flicker to be controlled.

Title: Thermal apparatus and process for removing contaminants from oil
Inventor: WHEELER CHARLIE
IPC: B01J19/28
Filed: 1996-09-27
Abstract: Used oil is treated in a thermal reactor to remove contaminants. The reactor comprises a rotating hollow vessel having side and end walls. The vessel is housed within a heating chamber. The inside chamber of the vessel is indirectly heated by conduction through the vessel walls. The vessel chamber is sealed and maintained at sub-atmospheric pressure. The chamber contains a permanently resident charge of non-ablating, coarse granular solids. Within the chamber, the oil is vaporized and pyrolysed, producing hydrocarbon vapour. Coke is formed as a byproduct. Contaminants, such as metals and halides, become associated with the coke. The coarse granular solids scour and comminute the coke to form fine solids. The fine solids are separated from the coarse solids and are removed from the vessel through an end wall. The hydrocarbon vapours are separated from any fine solids and are routed to a vapour condensation system for producing a substantially contaminant- free product oil. The contaminant-rich solids are collected for disposal.
