Title: Tire having silica reinforced rubber tread with outer, carbon black reinforced rubber strip
Inventor: NOWACKI MARC CHRISTOPHER
IPC: B60C19/08
Filed: 1997-07-02
Abstract: The invention relates to a rubber tire having a rubber tread intended to be ground-contacting which is relative electrically insulating and which has at least one thin, narrow, carbon black reinforced rubber strip integral the outer surface, or face, of said tread, each strip extending laterally across the tread to each of the tire's carbon black reinforced sidewalls.     In one aspect, said outer rubber strip, extends laterally across the outer surface of the tread which is designed to be ground contacting and connects with carbon black reinforced tire sidewalls to provide a path of reduced electrical resistance from the outer surface of the tire tread to the bead portion of the tire carcass and, thereby, such a reduced electrical resistance path from a vehicle to the road surface.     In another aspect, the said rubber tread intended to be ground-contacting, is primarily reinforced with silica.

Patent CA-2214790-A1 (CA)
Inventor: MILLER VAN
IPC: A23G1/56
Filed: 1997-02-03
Abstract: Milk chocolate may be prepared from a chocolate crumb, or other milk and sugar precursor component, by which the required amount of dried milk solids are provided for subsequent processing, together with at least some sugar. Later, the additional constituents for milk chocolate including remaining sugar, cocoa butter, cocoa liquor if the milk chocolate is not white milk chocolate, and so on, will be added and processed. In any event, a distinctive feature of milk chocolate is that it requires a caramel-like flavor ingredient to be brought into the milk chocolate formulation by the sugar constituent thereof.  However, rather than relying on heating processes whereby sugar will be at least partially caramelized, a caramel-like flavor may be brought into the sugar formulation using molasses, particularly molasses derived from sugarcane. Moreover, since molasses is the ingredient which provides a caramel-like flavor to brown sugar, and brown sugar itself comprises an intimate mixture of fine sugar crystals and molasses, where the molasses coats the fine sugar crystals, then brown sugar may be employed as well as to provide the caramel-like flavor ingredient to be carried into the milk chocolate formulation. The molasses or brown sugar is hydrated with milk, dried, and further processed by addition of the balance of sugar, fats, cocoa butter, and cocoa liquor if used; and the product is then set aside for subsequent pasting and conching operations which are typically used in the production of milk chocolate.

Title: Receiver for an optical communications system, filter device, and method for operating such a system
Inventor: PFEIFFER THOMAS
IPC: H04B10/67
Filed: 1998-05-25
Abstract: A receiver (R) is disclosed for receiving coded optical signals in an asynchronous optical transmission system using a CDMA method based on periodic spectrum encoding. The receiver (R) has a filter device (Rx) for decoding received signals as well as an optical detector unit (PD). The filter device (Rx) consists of a periodic filter (PRx) and a prefilter (VOR) whose transfer function causes the cosine transform of the optical frequency spectrum of the signal to be limited to a predeterminable range of a tuning curve. This reduces crosstalk between adjacent channels in the tuning range, and increases the maximum permissible number of transmitters.

Title: Improved method for correcting thermal drift in cardiac output determination
Inventor: HUGHES TIMOTHY J
IPC: A61M25/00
Filed: 1996-12-05
Abstract: A method and apparatus for correcting thermal drift in cardiac output measurements based upon a temperature signal indicative of the change in temperature of blood leaving the heart is disclosed. In a first preferred embodiment of a cardiac output monitoring system (10), the catheter (14) is provided with an electrical resistance heater (22). An electrical current having a sinusoidal waveform with a period of from 30 to 60 seconds is applied to the heater, causing power to be dissipated into the blood within a patient's heart (12). A temperature sensor (24) disposed near a distal end of the catheter produces a signal indicative of the temperature of blood leaving the heart. The temperature signal and the signal corresponding to the electrical power dissipated in the heater (an input signal) are filtered at a frequency .omega.n corresponding to the frequency of the applied electrical current, i.e., the frequency of the input signal. An output signal indicative of the temperature of the blood leaving the heart corrected for the effects of thermal drift is then calculated.     The blood temperature output signal is first split into two equal overlapping time periods. The two signals are then filtered separately to produce two partially independent output signals in the frequency domain. These two frequency domain output signals are then combined into a single corrected frequency domain output signal with the effects of thermal drift removed. The amplitude of the input power, the amplitude of the temperature signal corrected for thermal drift, and their phase difference are then used in calculating cardiac output.

Title: Procede de preparation d'ethers d'alkyle et de leurs melanges
Inventor: LINDQVIST PETRI
IPC: C07C43/04
Filed: 1996-12-19
Abstract: Ce procédé permet de préparer des éthers d'alkyles tertiaires, en particulier méthyle t-butyle éther (MTBE) et éthyle t-butyle éther (ETBE) ou des mélanges de ces éthers avec d'autres plus lourds. On introduit la charge de départ contenant des hydrocarbures dans un réacteur de distillation catalytique où des isooléfines, les isooléfines C¿4-7? en particulier, contenues dans cette charge sont mises en réaction avec un alcanol, en présence d'une résine d'échange cationique, pour donner des produits qui sont des éthers d'alkyle tertiaires. Le produit de réaction contenant les éthers est retiré du système de distillation sous forme d'un résidu et soumis, si nécessaire, à un traitement complémentaire pour la production d'un composant d'essence. On retire l'alcanol n'ayant pas réagi comme produit de tête de distillation. Le distillat retiré contient essentiellement un azéotrope d'alcanol et d'hydrocarbures C¿3? dont la quantité de C¿3? correspond au moins approximativement à la concentration d'hydrocarbures C¿3? dans la charge de départ d'hydrocarbures, une partie substantielle de l'alcanol n'ayant pas réagi étant retirée sous la forme dudit azéotrope. Ainsi, on évite le recours à une unité de lavage séparée pour l'alcanol dans une telle installation, ce qui réduit considérablement les coûts d'investissements concernant cette installation.
