Patent CA-2141997-C (CA)
Inventor: SHIMADA MICHIO
IPC: H04L9/14
Filed: 1995-02-07
Granted: 1998-09-29
Abstract: The invention provides a public-key cryptographic apparatus which does not leak information regarding a plaintext and can prevent an increase in block length.          A quadratic residue calculation circuit calculates a residue when the square of the lower n-1 bits of the plaintext of n bits is divided by public-key, and an exclusive OR circuit calculates an exclusive OR of the least significant bit of a result of the calculation and the most significant bit of the plaintext.  Then, public-key encipherment such as the RSA cryptosystem or a modified Rabin cryptosystem is performed twice repetitively for totaling n bits of the output of exclusive OR circuit and the lower n-1 bits of plaintext by public-key enciphering circuits so as to make it impossible to estimate the most significant bit of the plaintext from the ciphertext.

Title: Equal access to inter-exchange carriers in a mobile wireless packet data communication system
Inventor: EJZAK RICHARD PAUL
IPC: H04L12/56
Filed: 1995-06-22
Granted: 1998-10-06
Abstract: The present invention discloses an improvement to a wireless packet data communication system by permitting a subscriber using a mobile end system (M-ES) to select the inter-exchange carrier (IXC) which will carry the data over those network paths for which the subscriber bears the cost during a particular communication session.  The present invention allows the subscriber to specify a preferred inter-exchange carrier in an optional preferred IXC field added to an end system hello message.  During registration and authorization procedures, an identifier corresponding to the preferred inter-exchange carrier is transmitted between a serving mobile data intermediate system (MD-IS) and a home MD-IS in a preferred IXC field added to standard registration protocol messages.  If the subscriber has specified a preferred inter-exchange carrier in the preferred IXC field, then this preferred inter-exchange carrier is given higher priority than a default preferred inter-exchange carrier selected when the user subscribes to the network services.  Each MD-IS is provided with a new database that maps inter-exchange carrier identifiers to a corresponding boundary router address associated with the preferred inter-exchange carrier in order to route data packets via the subscriber's preferred IXC.  The present invention thus allows data to be sent over the subscriber's preferred inter-exchange carrier on paths in both the forward and reverse directions on a per session basis.

The upward curvature is preferably a radius that slopes upwardly at a declining rate with increasing distance from the respective cutting face junctures.  A third cutting face at the nose adjoins the side connected faces preferably at a common angle.  Various additional features are also disclosed.

Granted: 2005-03-15
Abstract: A process for solvent dewaxing a waxy oil feed to obtain petroleum oil lubricating stock comprising the steps of contacting a warm waxy oil feed by indirect heat exchange first with cold filtrate, then with refrigerant to crystallize and precipitate the wax in the oil feed to form an oil/solvent/wax mixture. The oil/solvent/wax mixture is diluted with cold solvent to adjust the viscosity of the mixture and the mixture is filtered to remove the wax from the cold oil/solvent/wax mixture. A cold wax cake is recovered and a cold oil/solvent filtrate stream is recovered. The cold ail/solvent filtrate stream is fed, at the filtration temperature, to a selective permeable membrane. The membrane selectively separates the cold filtrate into a cold solvent permeate stream and a cold filtrate stream which contains the dewaxed oil and the remaining solvent.

Title: Tire having silica reinforced rubber tread with outer cap containing carbon black
Inventor: CRAWFORD MICHAEL JULIAN
IPC: B60C1/00
Filed: 1995-10-11
Granted: 2006-04-04
Abstract: The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is quantitatively reinforced with silica and which, in turn, has a thin, integral, rubber outer cap on its outer surface which contains a quantitative amount of carbon black.        In one aspect, said outer cap, sometimes referred to herein as an outer top cap, extends across the outer surface of the tread which is normally intended to be ground contacting and in an alternative aspect, the outer top cap extends only over the outer portion, namely the peripheral edges, of said tread surface intended to be ground contacting.        The outer, carbon black reinforced, rubber tread top cap connects with at least one other carbon black reinforced rubber component of the tire in a manner to provide a path of reduced electrical resistance from said outer tread top cap to the bead portion of the tire carcass and, therefore, such a path from the vehicle to the road surface.
