Filed: 1998-01-21
Abstract: Simplified hinge structures for vehicle body closures provide a plurality of pivot axes that are aligned with a common intersection point above a body opening closed by a closure panel hinged to the vehicle body.  A panel mount defines a first axis while a body mount defines  a second axis.   A pair of  links are pivotally secured together between the panel mount and the body mount to complete a hinge set.  Preferably, a pair of hinge sets are secured to the hinge side of the closure panel, the hinge sets providing a panel hinge axis positioned to align said panel for movement in a non-interfering  path  with  respect  to  body  portions adjacent the path.  Preferably, the hinge axis is also positioned outward of the opening away from the hinge side of the panel, and external to the body opening, to avoid interfering displacement paths of the lid with respect to conventional body opening stylings.  Preferably, the hinge structure is combined with a simple torsion biasing spring.
Patent CA-2234269-A1 (CA)
Inventor: BERKLEY STANLEY G
IPC: G01N23/20
Filed: 1996-09-24
Abstract: Improved methods for managing a population of metal components subject to fatigue failure are provided. The residual compressive stress in the critical surfaces of such components, especially in areas of high stress concentration, are measured non-destructively using x-ray diffraction techniques. The measured surface residual compressive stress is used as a management criterion. A component having a surface residual compressive stress greater than a predetermined value can be returned to service. However, once the measured surface residual compressive stress of a component falls below the predetermined value, it can either be removed permanently from service, or it can be reworked to increase its surface residual compressive stress and then returned to service. Additionally, by measuring the surface residual compressive stress of an individual component, the remaining service life of that individual component can be estimated. These methods for management of polulations of such metal components allow for increasing the service life of the components in a safe and effective manner. Methods are also provided for the manufacture and/or design of metal parts with improved performance criterion (e.g., reduction in weight) while maintaining acceptable service life. Methods are also provided for establishing quality control procedures using surface residual compressive stress measurements during and/or after the manufacturing process in order to prevent, for example, introduction of metal parts having insufficient surface residual compressive stress levels for their intended use.
Patent CA-2235153-A1 (CA)
Inventor: SMED JAN PEER
IPC: F01D25/12
Filed: 1996-09-05
Abstract: A variable area restrictor is disclosed that is preferably used in a turbine engine to provide improved matching between the pressure required for aerofoil cooling and the somewhat lower pressure requirement for supplying air to the interstage seals and disc cavities. In a preferred embodiment, the valve of the present invention comprises a spring loaded valve assembly with a fixed minimum flow area controlled by pre-setting a minimum dimension for the opening between an inlet and the housing or body of the valve. A pre-loaded spring maintains the lift at this minimum dimension until the pressure drop across the flow area exceeds a certain value. Above this critical pressure drop, the valve lifts, causing the flow area to increase, and thereby reducing the supply pressure that would be otherwise necessary to achieve a disc cavity flow adequate to maintain the temperatures within specifications.

Title: Iron fortified chocolate-flavored beverages including edible acids or their salts
Inventor: MEHANSHO HAILE
IPC: A23L1/304
Filed: 1997-01-29
Abstract: Nutritional chocolate-flavored beverage mixes and other edible mixes that are fortified with highly bioavailable sources of iron such as ferrous fumarate and ferrous sulfate, yet do not develop undesirable gray color when the beverage mix is reconstituted with water or milk, even when the water or milk has been boiled. This problem of gray color development is solved by including edible acids such as citric or malic acid as buffering agents in the beverage mix so that the pH of the reconstituted chocolate beverage is about 6.5 or less. An additional benefit of including these edible buffering acids/salts is that they tend to stabilize the chocolate aroma in the reconstituted beverage. Inclusion of these edible buffering acids/salts in ready-to-serve chocolate-flavored beverages fortified with these highly bioavailable iron sources also prevents the formation of undesirable gray color.

Abstract: An equipment (1) for the suppression of whole echoes composed of several partial echoes in telecommunications (TC) equipment, such as end devices, transmission systems or exchange equipment, with the help of adaptive FIR  (=Finite Impulse Response) filters, which reproduce the whole echo and extract it from the echo-laden useful signal and which has been transferred to the respective TC equipment, in which the homogeneous FIR filters or partial filters (10), each of which are able to reproduce a whole echo or partial echo, are implemented on a single ASIC (=Application Specific Integrated Circuit) (9) for the m parallel and independent TC channels n to be served; and in which the whole echoes or partial echoes to be reproduced can be calculated in real time in the ASIC (9) and in which a digital signal processor (4) is designed to control the ASIC (9) and set the filter settings, especially after the coefficient required to reproduce the echo is calculated on the ASIC (9). This calculation is carried out in the digital signal processor (4). This makes it possible to effectively suppress echoes in a large number of m parallel and independent TC channels, as they must be processed in exchanges and network hybrids, without requiring a large amount of memory space and computational effort.

Title: Tire innerliner composition
Inventor: BENKO DAVID ANDREW
IPC: C08L23/28
Filed: 1999-01-20
Abstract: A halobutyl rubber is generally used in the innerliner of pneumatic tires to retard the escape of air used to inflate the tire, thereby maintaining tire pressure.  Since halobutyl rubbers, such as bromobutyl rubber, are generally the most expensive elastomers used in tires, it is desirable from a standpoint of cost reduction to reduce the level of halobutyl rubbers used in tires.  The present invention relates to a technique for reducing the quantity of halobutyl rubber utilized in the innerliner of tubeless pneumatic vehicle tires.  The present invention more specifically relates to a tire innerliner and pneumatic tires containing the same, which are prepared from a composition comprising, based on 100 parts by weight of rubber, a blend of (1) about 50 parts to about 90 parts of a halobutyl rubber and (2) about 10 parts to about 50 parts of a styrene-isoprene-butadiene terpolymer rubber having a first glass transition temperature which is within the range of about -110°C to about -20°C and a second glass transition temperature which is within the range of about -50°C to about 0°C, wherein said styrene-isoprene-butadiene terpolymer rubber contains about 20 weight percent to about 40 weight percent bound styrene.

Abstract: A gas appliance includes a pair of separate manifolds which each supply gas to two burner assemblies.      Each manifold includes a relatively short and straight steel tube having a central section with a generally square-shaped cross-section and end sections with generally circular-shaped cross-sections, and a pair of end plugs closing the end sections to form a sealed interior space.

A pair of bolt-through type valves are associated with each of the manifolds to regulate flow of gas from the manifolds to the burner assemblies. The valves have inlets directly secured to the manifolds and outlets connected to the burner assemblies with burner tubes. A pair of light-weight aluminum supply tubes connect a gas inlet with the two manifolds. The supply tubes are preferably secured to the manifolds with bolt-through type adapters located at the longitudinal centers of the manifold tubes and between the two valves.
