Abstract: An anti-reflection coating that is soil resistant and easy to maintain is provided on a transparent substrate (10). Optionally, an adhesion-promoting layer (10A) may be provided between the substrate and anti-reflection coating. The anti-reflection coating comprises a multilayer film (11, 12) having: alternating layers of high and low refractive index materials that are transparent over a wavelength region near 550 nm. The multilayer film is formed by reacting metal with non-stoichiometric amounts of oxygen such that the coating has one or more layers of electrically conductive metal oxide material. The resultant conductivity prevents large static potentials from being developed on the coated substrate. The coating is particularly suited for ophthalmic applications.

IPC: F22G7/14
Filed: 1997-12-16
Abstract: Suspended superheaters (52 and 53) alone are provided in the outlet of a furnace. The heat transfer areas of these superheaters are determined so that the temperature of exhaust gas in the rear flow thereof may be 1000-1100 ~C  under the maximum load of a boiler. The passages of the exhaust gas in the rear flow of the superheaters (52 and 53) are divided into subpassages along the flow of the exhaust gas and a damper for regulating the flow rate of the exhaust gas flowing through each subpassage is provided at an outlet of each of the subpassages. A horizontal reheater (41) is provided for the subpassages. Since the temperature difference between the temperature (1000-1100 ~C) of the exhaust gas flowing around the reheater (41) and the temperature of steam flowing through the reheater (41) is large, a highly effective heat exchange can be conducted for even a small heat transfer area.  Accordingly, an increase in the heat transfer area of the reheater (41), that is, in the size of the whole, can be suppressed.

Title: Adaptive communications formatting
Inventor: PAULS RICHARD JOSEPH
IPC: H04L1/00
Filed: 1998-09-21
Abstract: The present invention is a method for improving data transfer performance over communications networks connecting data networks and users using adaptive communications formatting. Adaptive communications formatting includes encoding (or compressing) the data and applying error control schemes to reduce the amount of data being transmitted and to correct and/or conceal errors occurring during data transmission. In one embodiment, the present invention uses a set of transcoding techniques to encode (or compress) the data and a set of error control schemes to correct and/or conceal errors occurring during data transmission. The particular sets of transcoding techniques and error control schemes selected to format the data are adaptive to factors, such as the nature of the communications network connecting a user to an access server on the data network, the preferences of the user, and the data type of the data being transmitted to the user (or the access server).

Title: Composite filled hollow structure
Inventor: GREENE ROBERT H
IPC: E04H17/20
Filed: 1996-03-29
Abstract: A filled hollow structure (10), such as a fence post, which is constructed with a hollow member (14) filled with a core (12) to increase its strength.  One aspect of the structure is that the core material normal expands upon setting, so that, when hardening within the hollow member, the expansion is restrained by the hollow member and the core is formed into an integral structure with the hollow member. Further strength is added by constructing the hollow member of reinforced fiberglass with the fiberglass rovings oriented at an angle to the axis of the pipe and by using a hard coating (18) on the outside of the pipe.

Patent CA-2251216-A1 (CA)
Inventor: AUTH DAVID C
IPC: A61B18/14
Filed: 1997-04-10
Abstract: An apparatus and method for use in performing ablation of organs and other tissue includes an electrode carrying member which is substantially absorbent and/or permeable to moisture. The electrode carrying member is mounted to the distal end of an elongate shaft, and an array of electrodes is mounted to the surface of the electrode carrying member. Following placement of the ablation device into contact with the tissue to be ablated, an RF generator is used to deliver RF energy to the electrodes and to thereby induce current flow from the electrodes to tissue to be ablated. As the current heats the tissue, moisture (such as water vapor or liquid) leaves the tissue causing the tissue to dehydrate. The moisture permeability and/or absorbency of the electrode carrying member allows the moisture to leave the ablation site so as to prevent the moisture from providing a path of conductivity for the current.

Title: Method for determining the phase difference of light waves propagated over two paths
Inventor: BUNN JAMES S JR
IPC: G01J9/00
Filed: 1998-11-18
Abstract: The invention is a method for obtaining a measure of the light propagation time difference for two light-propagating-media paths. The first step consists of generating two substantially-identical frequency-modulated light waves whereby the frequency of the light waves is offset from a reference frequency by a different frequency increment for each basic time interval in each of a plurality of groups of three or more basic time intervals. Each frequency increment is the sum of a specified increment and a frequency-modulation-error increment. The frequency-modulation-error increments associated with the specified increments are independent of each other and unknown. The second step consists of feeding the two light waves into the entry points of two light-propagating-media paths having a light propagation time difference and obtaining a combination light wave by summing the light waves emerging from the exit points of the two light-propagating-media paths. The third step consists of calculating an estimated corrected or estimated uncorrected phase measure of the light propagation time difference for the two paths for a plurality of groups using only measured properties of the combination light wave.
