Patent CA-2323446-A1 (CA)
Inventor: EJAZ UL HAQ
IPC: G06F12/00
Filed: 1999-03-08
Abstract: A system of the present invention uses small swing differential source synchronous voltage and timing reference (SSVTR and /SSVTR) signals to compare single-ended signals of the same slew rate generated at the same time from the same integrated circuit for high frequency signaling. The SSVTR and /SSVTR signals toggle every time the valid signals are driven by the transmitting integrated circuit. Each signal receiver includes two comparators, one for comparing the signal against SSVTR and the other for comparing the signal against /SSVTR. A present signal binary value determines which comparator is coupled to the receiver output, optionally by using XOR logic with SSVTR and /SSVTR. The coupled comparator in the receiver detects whether change in signal binary value occurred or not until SSVTR and /SSVTR have changed their binary value. The same comparator is coupled if the signal transitions. The comparator is de-coupled if no transition occurs. The system may use a first set of oscillating references on a first bus for detecting transitions in control information and a second set of oscillating references for detecting transitions in data information.

Title: System and method for increasing cdma capacity by frequency assignment
Inventor: O'BYRNE VINCENT A
IPC: H04W16/12
Filed: 1999-03-23
Abstract: A system increases the capacity of a CDMA network having a plurality of cell sites (4110, 4120, 4130). The system defines a pool of frequencies (F1, F2) available for assignment, and assigns one of the available frequencies (F1, F2) to each of the cell sites (4110, 4120, 4130) so as to minimize the number of neighboring cell sites assigned a same one of the available frequencies (F1, F2). By deploying different frequencies (F1, F2) in the cell sites (4110, 4120, 4130), the amount of interference caused by neighboring cell sites reduces. As a result, the capacity of each of the cell sites (4110, 4120, 4130) operating at a single frequency (F1 or F2) can be increased, so long as there remains sufficient power to reach the mobile units (4200) operating within the cell site (4110, 4120, 4130). The system attains maximum benefits when the cell sites (4110, 4120, 4130) are located close together and the propagation exponent is low (for example, 10-20 dB/decade).

Abstract: TITLE: PAD-TYPE IDLER FOR BELT CONVEYORS Note to the attention of the Commissioner of Patents: This application is incomplete. This application is filed under the provisions of the Patent Rule # 93. The sections relating to the Field of Invention; Background of the Invention; Summary of the Invention; Description of the Drawings; Detailed Description of the Preferred Embodiment; Abstract of the Disclosure; and a number of additional claims will be added at a later date. The enclosed informal sketches will also be replaced by CAD drawings at that time. The pad-type idler according to the present invention comprises a rectangular pad made of a mixture of Teflon TM and carbon graphite. The pad is supported on a metal structural angle. The pad has on its bottom surface, a pair of angled longitudinal grooves that are used to mount the pad to the metal support angle. Each leg of the metal support angle make an angle of 45 degrees with the plane of the pad. The pad further has a plurality of cavities through its bottom surface, some of these cavities are between the longitudinal grooves. The depth of the cavities is slightly more than the depth of the longitudinal grooves, such that upon wear of the pad in use, the cavities are exposed to the belt side of the pad before the longitudinal grooves become exposed. Therefore, upon wear of the pad to the point of exposing the cavities, dust from the conveyor belt surface quickly accumulates inside the support angle. The support angle forms a triangular receptacle extending along the length of the pad and to the side of the pad. The dust accumulating in this receptacle is easily seen 1 or felt by the touch by a maintenance worker walking along the conveyor, to detect a pad which needs replacement. Worn pads can thereby be replaced before the metal support angle protrudes though the longitudinal grooves of the pad and damage the belt of the conveyor. It was also discovered that in some industrial applications, a glaze forms on the surface of the pad to protect the pad against wear. 2

Title: Mechanical hydroforming with improved lubrication
Inventor: ELIZONDO EDWARD
IPC: B21D26/02
Filed: 1999-09-02
Abstract: A process of mechanical hydroforming, in which a hollow tube is caused to expand against the interior surface of a die that surrounds the tube by hydraulic pressure applied to a liquid that fills the interior of the tube, is improved by coating the part of the exterior surface of the tube that comes into contact with the die surface against which it expands with a wax that is solid at normal room temperature but can be maintained fully melted and in contact with air, without showing any visible evidence of decomposition, at a temperature that is at least 75 ~C. Preferably, the wax is applied to the surface to be hydroformed by spraying from melt onto the surface while the latter is maintained above the melt temperature of the wax. Shortly after the wax has been thus applied to the surface, the wax is cooled until it solidifies. Most preferably, the wax is an "oxidized hydrocarbon" wax that is about 95 % hydrocarbon and 5 % straight chain carboxylic acids and contains a wide variety of molecular weights of both hydrocarbons and carboxylic acids.

IPC: C08J9/12
Filed: 1999-08-31
Abstract: The invention disclosed provides a method for producing ultramicrocellular polymer foams at low pressures. A polymer is saturated with a blowing agent at low temperatures and pressures within a short time period, due to retrograde vitrification. The blowing agent may be in the form of a gas or a volatile liquid. Polymer-blowing agent combinations are selected to provide a processing temperature/pressure in the area below the positive slope portion of the retrograde vitrification profile of the glass transition temperature of the polymer versus pressure. The polymer thus saturated has an exceptionally high blowing agent content, and is then foamed to produce materials with small cells and high cell density.
