Patent CA-2137733-A1 (CA)
Inventor: WILLARD WALTER L JR
IPC: B60C13/00
Filed: 1994-12-09
Abstract: A run-flat tire the weight, space and convenience advantages of which can be substantial.  This is especially true for the urban-economy car or family type vehicles which have limited space available for a spare tire and inadequate space for the removed flat tire.  These vehicles also have higher comfort requirements that must be addressed.  The mini-space solution to the flat tire problem has very limited performance capabilities.   Other solutions include major modifications in the rim and/or the tire, which are not cost effective or compatible with a conversion to standard tires on the same rims.   The run-flat tire of this invention includes thickened sidewall portions, a belt package with a cap ply, lower sidewall rubber support portions, a specially designed bead seat area with a rim seat ply and three carcass layers.   The classical problems of inflated vs. deflated performance  tradeoffs  in  ride  comfort,  handling,  radial stiffness  and  endurance  of  the  tire  are  substantially improved.  This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and a rim that can be used interchangeably with the standard tire. The run-flat tire system of this invention is capable of maximum lateral accelerations under nominal operations of approximately 0.90 gS and extended operating efficiency (i.e., handling  and  durability)  at  higher  speeds  for  longer distances.

Title: Chemical vapor deposition from single organometallic precursors
Inventor: BARRON ANDREW R
IPC: H01L21/20
Filed: 1993-06-18
Abstract: A method is disclosed for forming a passivating/buffer film on a substrate. The method includes heating the substrate to a temperature which is sufficient to cause a volatilized organometallic precursor to pyrolyze and thereby form a passivating/buffer film on a substrate (42). The organometallic precursor is volatilized at a precursor source (38). A carrier gas is directed from a carrier gas source (26) across the precursor source (38) to conduct the volatilized precursor from the precursor source (38) to the substrate (42). The volatilized precursor pyrolyzes and is deposited onto the substrate (42), thereby forming the passivating/buffer film on the substrate. The passivating/buffer film can be a cubic-phase passivating/buffer film. An oxide layer can also be formed on the passivating/buffer film to thereby form a composite of the substrate, the passivating/buffer film and the oxide layer.  Cubic-phase passivating/buffer films formed by the method of the invention can be lattice-matched with the substrate. Electronic or electro-optical circuits or circuit elements can be formed which include passivating/buffer films formed by the method of the invention.

Abstract: An arrangement for noise removal according to the present invention includes a microphone and an acoustic high-pass filter positioned in front of the microphone and consisting of the combination of an acoustic resistance, an acoustic compliance and an inertance.          According to the invention, the acoustic resistance is composed of nonwoven fabric; the acoustic compliance, of a cavity; and the inertance, of a thin cavity connected to said cavity.  This acoustic high-pass filter reduces unpleasant noise which arises from the microphone when a low-frequency high-pressure air stream, such as the speaker's breath, hits the mouthpiece of the telephone.

Patent CA-2153269-A1 (CA)
Inventor: WALSH ROBERT C
IPC: F16L11/12
Filed: 1995-06-05
Abstract: A system for pumping liquids that may be subject to solidification in the line, uses a compressed gas as an expulsion medium for the liquid. A compound hose pipeline is used, having a variable volume gas chamber adjacent a compressible transfer passage, both of which extend the length of the line.  The line may comprise an outer hose that provides a gas annulus about a collapsible inner hose, through which inner hose the pumped liquid can flow.  Air or other gas within the annulus operates to expel the liquid by compressing the inner hose.  A compartmented hose embodiment has a separating diaphragm running the length of the hose, dividing the hose into expansible gas and liquid portions.  The system may be self priming, using a source of vacuum to remove the air and expand the volume of the liquid transfer hose portion, to thereby induce filling of the transfer flow portion of the hose or pipeline, followed by an emptying phase, by re-applying air pressure.  A Shrader-type valve or a needle inflator valve in the line outer wall may provide convenient access for inflation air.  The delivery system can use piston or centrifugal type pumps; or a gas compressor can serve as the sole pumping medium.  An immersed intake for use with the system in fresh water can incorporate a fine filter cloth against zebra larvae or other contaminants, which filter is back-flushed at the end of each pumping cycle.  The line, when being operated to serve as a pump may be duplexed, so as to provide more continuous flow.  An inner hose may be used that is normally in a flattened condition, thereby incorporating an initial charge of atmospheric air upon sealing the line ends, while its "memory" assists in dewatering.  A discovered air pressure "bump" when dewatering further contributes to system effectiveness.  The co-extensive hose may be manufactured by co-extrusion, in endless length, thus removing the limitation of having to thread the inner hose within the outer hose.

IPC: H04L12/46
Filed: 1995-08-10
Abstract: A gateway system for connecting first and second communication networks has first and second network end nodes and a protocol converter. The gateway system operates to provide input-output services of both network protocols to users of both networks in communicating through the gateway system. The gateway system employs associated complement protocol circuits in the end nodes and the protocol converter to provide these services. An efficient technique for generating the complement protocol of a first network is to prune finite state machines representing the operation of the second network protocol to provide the services of the second protocol that are not provided by the first protocol. The complement protocol circuits for the second network are then constructed based on the pruned finite state machines representing the operation of the first protocol.

Abstract: A simultaneous voice and data (SVD) modem includes a preemphasis filter for processing an audio source signal, e.g., a voice signal, before transmission to a far-end SVD-capable modem. The preemphasis filter implements a second order linear predictor in which a quantized  set of predictor coefficients are selected directly from the normalized autocorrelation coefficients. In addition, an index is associated with the selected set of predictor coefficients. This index is transmitted to an oppositeSVD-capable modem, which thereby allows the opposite SVD-capable modem to selectthe same set of predictor coefficients for use in recovering the voice signal at the opposite endpoint.
