Patent CA-2482033-A1 (CA)
Inventor: LOCKETT STEVEN G
IPC: C10N40/25
Filed: 2004-09-17
Abstract: The present invention is directed to a novel process for making Group II metal overbased sulfurized alkylphenols, which process uses alkylene carbonate as both a source of carbon dioxide and alkylene glycol. In particular, under the reaction conditions using ethylene carbonate, carbonation time is reduced to about one quarter the time taught in the prior art to make Group II metal overbased sulfurized alkylphenol compositions. The present invention is also directed to a detergent-dispersant additive composition comprising a Group II metal overbased sulfurized alkylphenols, wherein the Group II metal overbased sulfurized alkylphenols have a reduced color as measured by ASTM Test No. D 6045 and an increased hydrolytic stability as measured by a modified ASTM Test No. 2619. The present invention is also directed to a process using ethylene carbonate or alkyl-substituted ethylene carbonate and water for delivering in situ equimolar quantities of ethylene glycol and carbon dioxide for use as reactants in chemical reactions.

Title: Apparatus and method for bending coated glass using microwaves
Inventor: VANDAL ROBERT A
IPC: C03C23/00
Filed: 2003-06-26
Abstract: An apparatus and method for bending glass substrate(s) are provided. Microwave radiation is used to heat glass substrate(s) for bending. As a result, a coating supported by the substrate(s) is not heated as much during the bending process compared to if only conventional IR radiation was used. Thus, more extreme degrees of glass bending may be achieved, and/or the likelihood of coating damage reduced.

Inventor: LOPEZ MEDRANO ALVARO
IPC: H04B1/707
Filed: 2003-12-12
Abstract: The invention relates to a method and apparatus for the outer loop of the power control system of a mobile communication system, which form a cellular infrastructure and which can be used to meet a quality-of-service (QoS) specification determined with the minimum level of power necessary. The inventive outer loop is used to fix the desired signal-to-interference targe t ratio, SIRtgt, which meets the quality-of-service specification required in a radio environment that is characterised using stochastic models. The inventi ve method consists in applying the iterative Newton-Raphson method to numerical approximations of the different cut-off probability distribution functions (QoS) in different propagation environments. In this way, once said probability has been fixed and the second-order statistical moments specific to each statistic considered have been estimated dynamically, the margin on the median SIR is obtained as well as the SIRtgt corresponding to said cut-o ff probability.

IPC: A61B3/103
Filed: 2004-01-20
Abstract: A system for measuring the eye comprising a light source (10) which sends a narrow collimated beam of light (12), to reflect from a beam splitter (14).  The beam of light (12) enters the eye (16) through the pupil (17) where it is focused to a point (20) on the retina (18). The light (12) is reflected from the retina (18) where it passes through a series of relay lenses (22, 24). The light then passes through one or more reticles (26, 28). A CCD camera (30) records the shadow pattern formed by reticles (26, 28). The shadow pattern is digitized into a computer and algorithms are created to calculate the distortions. As a result of the above steps being performed, the refractive power of the eye, with or without corrective lenses in place, can be measured at many points, simultaneously.
