Abstract: A gas fired infrared radiant heating system of improved thermal output. The present invention solves problems associated with prior art designs by providing a single gas delivery system for delivering combustible gas to two or more burner assemblies. The invention consists of a burner housing (10) with two or more burner assemblies (18), each of which can be connected to a typical radiant tube heat exchanger assembly (12). The homer housing contains a single gas delive ry system including a valve (14), a single control circuit module (30), a single blower proving switch (50), and a single manifold (16) which will distribute the gas to the multiple radiant tube heat exchanger assemblies (12). In addition, in positive pressure configurations, the burner housing will also have a single air fan (38), whereas in negative pressure configurations of the heating system one or more exhaus t fans may be utilized. The foregoing design will provide a higher thermal output without the heat distribution and installation cost problems of the currently available infrared heaters.

Title: Optimizing updatable scrollable cursors in database systems
Inventor: HURAS MATTHEW A
IPC: G06F17/30
Filed: 2000-10-06
Granted: 2005-04-12
Abstract: An optimization for updatable scrollable cursors in database systems. To ensure that a temporary copy of a data record matches the data record maintained in the database, the temporary copy is associated with a timestamp included on each page storing the data records of the database. The timestamp on a page in the database is updated whenever any record stored on the page is updated. The optimization compares the timestamp stored with the temporary record with the current timestamp associated with the page on which the data record is stored in the database. If the two timestamps are matching then the temporary record is identical to the database table record and there is no need to carry out a comparison of the attribute values of the temporary record with the record in the database table.

Abstract: The present invention provides a gasket for use in a service portion of a brake control valve in a railway braking system. The gasket comprises an elastomeric composition with a predetermined shape. There is a series of bead-like projections formed on the first surface of the gasket for sealing such gasket with a body portion of the valve. A first aperture is disposed in the gasket at a predetermined location for engagement with a projection on the filling piece of the service portion. A brass insert is molded into the elastomeric composition and has a second aperture formed therein. The second aperture is in fluid communication with an auxiliary reservoir of such railway braking system. A third aperture is formed in the gasket in a third predetermined location. A brass insert, which has a first predetermined configuration, is molded into the elastomeric composition of the gasket. The brass insert is disposed in a lower quadrant of the first surface of the gasket and has a fourth aperture disposed therein having a second predetermined configuration. The fourth aperture is in fluid communication with a brake pipe. There are bead like projections formed on the opposed planar second surface of the gasket that correspond to similar positions, but radially opposed, for each of the bead like projections formed on the first surface of the gasket. The bead like projections formed on second surface are for sealing contact with such filling piece of such service portion.

Filed: 2001-06-04
Granted: 2009-08-11
Abstract: Packaging and processes for facilitating fast, efficient, and reliable production line packaging of products, and more particularly perishable products including meat products. Product trays according to the present invention are formed of non-foam plastic material with three dimensional structure and configuration that imparts an esthetically pleasing appearance and feel to the customer at the point of sale, as well as offering to the consumer a container that is microwavable, dishwasher safe and freezer safe in addition, if desired, to being recyclable. Such packaging and processes are particularly useful in newly emerging automated supply chains where inventory sales are tracked to support centralized processing of meat and other perishable products at centralized facilities for shipment to geographically distant points of sale. In these situations, the packaging must present the requisite esthetic, convenience and performance qualities to the customer at the point of sale even after having been loaded into a shipment container, transported often by truck over hundreds of miles, unpacked and placed in the product display case. Non-foam containers according to the present invention can accomplish these results by featuring separation structure to permit manufacture, storage, stacking, shipment, and dispensing on processing lines with minimum chance or potential of the sort of locking together which can otherwise occur with non-foam containers.

Abstract: The present invention is directed toward a stabler leveling mechanism for tree harvesters. The present invention utilizes many of the same components of conventional leveling mechanisms for tree harvesters, but it alters the pivot axis of a swing-house assembly. A conventional swing-house assembly pivots about an axis parallel to the top surface of a carriage on level ground. That conventional assembly can be deleterious, therefore, applicant has altered the pivot axis of the swing-house assembly. Admittedly, merely moving the pivot axis seems simple but it is difficult. The components had to be constructed differently to obtain the desired results and simultaneously make the device stable within the working environment.
