Patent CA-2045455-A1 (CA)
Title: Motor fuels of enhanced properties
Inventor: HANLON JOHN V
IPC: C10L1/30
Filed: 1991-06-26
Abstract: Environmentally-friendly fuels are provided comprising a gasoline fuel composition having a Reid vapor pressure (ASTM test method D-323) of 8.5 psi (58.6 kPa) or less, and preferably 8.0 psi (55.2 kPa) or less, containing up to 1/32 gram of manganese per gallon (0.008 g/liter) as at least one fuel-soluble cyclopentadienyl manganese tricarbonyl compound. Such motor fuels have improved octane quality as compared to the clear base fuel, and thus do not require the use of increased proportions of aromatics in the fuel. In addition, the motor fuels contribute to clean air by resulting in less evaporation into the atmosphere during such operations as storage and dispensing to vehicles and by resulting during engine operation in reduced emission of carbon monoxide (CO) and oxides of nitrogen (NO x) while having little effect on the level of tailpipe hydrocarbon emissions. The fuels exhibit virtually no adverse effect upon exhaust gas catalysts of the type commonly used in present-day vehicles. Because the base fuels can contain reduced volumes of aromatics, the antiknock response of the fuels to the addition of the cyclopentadienyl manganese tricarbonyl compounds remains high.

Title: System for validating the authenticity of a transaction employing electronic receipts
Inventor: FRANCINI JOSEPH P
IPC: G07G1/00
Filed: 1991-08-01
Abstract: ABSTRACT      A method is disclosed for validating the authenticity of a transaction.  In the subject method, a digitized code signal representative of the signature of the purchaser is generated at the point of sale by the transaction terminal.  This code signal along with the parameters of the transaction are stored electronically.  In the event that the customer questions the transaction, the financial institution associated with the merchant can generate a hard copy receipt which includes the parameters of the transaction as well as a representation of the signature of the purchaser.  This hard copy receipt is then sent to the customer for validating the transaction.  The approach disclosed herein eliminates the need to generate, transfer and store hard copy receipts unless they are specifically requested.

Title: Method for controlling basis weight in the production of stretchable webs
Inventor: BEUTHER PAUL D
IPC: D21F7/06
Filed: 1991-08-23
Abstract: ABSTRACT In the manufacture of stretchable webs such as creped tissue, nonwovens, and the like, in which the web is formed and thereafter wound onto a reel, basis weight control of the web on the reel is accomplished by measuring the speed and basis weight of the web prior to winding the web onto the reel and calculating the basis weight of the web on the reel.  In response to this calculated value, either the upstream flow of material or the downstream speed of the web (reel speed) are adjusted to obtain the desired basis weight of the web at the reel.

Abstract: ABSTRACT            The invention provides a method and apparatus for making an electrochemical cell solid electrolyte holder. A layer of solid electrolyte powder or its precursor is formed around an externally screw threaded mandrel. The powder is pressed to form the holder in a green state with internal threads formed by the mandrel. The mandrel is screwed axially out of the green holder,  after which the green holder  is sintered. In the apparatus there is a mandrel which has external threads, and a flexible sheath.  The mandrel is receivable in the sheath to provide an annular space around the mandrel for receiving a powder to be isostatically pressed by the sheath.  The space is provided between the sheath and a mould, but can, instead, be provided between the mandrel and sheath, or between two sheaths between the mould and mandrel.

Title: Method of forming interlayer-insulating film
Inventor: SATO NOBUYOSHI
IPC: H01L21/768
Filed: 1991-09-20
Abstract: Method of Forming Interlayer-Insulating Film Abstract of the Disclosure A silicon oxide film to be used as an interlayer-insulating film in a semiconductor device is formed by a high pressure organic silane-O3 CVD. A semiconductor wafer is placed in a reaction vessel and is heated at a temperature of 400°C.  A mixture of an organic silane gas such as TEOS, HMDS and OMCTS and an ozone gas is introduced into the reaction vessel and the reaction is carried out at a pressure higher than the atmospheric pressure, preferably at a pressure of about 2 Torr to form a silicon oxide film having excellent properties.  A life time of the ozone gas which serves as an oxiding agent and/or catalyst can be prolonged under the high pressure, and therefore a deposition rate of the silicon oxide film ca be increased and the flatness of the silicon oxide film can be improved.  Therefore, the silicon oxide film forming process can be performed efficiently and a flatenning process after the formation of the silicon oxide film can be made simpler.
