A point-of-sale system automatically processes a credit towards a pre-registered upsell along with a conventional transaction. The system receives an identifier pursuant to the transaction which is used to determine the pre-registered upsell and instructions for adjusting a purchase price from the transaction to provide the upsell credit. The instructions may direct, for example, that the purchase...

A POS terminal (10) generates a purchase price of a purchase, and generates a rounded price. The rounded price may be, for example, the lowest whole number greater than the purchase price. The POS terminal (10) then calculates a round-up amount (change due to the customer) as the difference between the purchase price and the rounded price. The coupon value (414) is set based on the round-up amount...

In accordance with the present invention, a store controller determines a monetary value, such as an amount of spare change due to a customer. The store controller also selects a ticket record that includes a set of ticket numbers. Subsequently, the store controller purchases at least one lottery ticket based on the monetary value and the set of ticket numbers. The store controller then outputs th...

The DataTreasury System provides comprehensive support for the processing of documents and electronic data associated with different applications including sale, business, banking and general consumer transactions. The system retrieves transaction data such as credit car...

The method for encapsulating a space or object to render it dust-tight comprises applying a layer of material around essentially the entire periphery of the space or object, and bonding at least part of the material to it. A film is used as the layer of material and at least part of it is subjected to a heat treatment step. Also claimed is the film used.

A method of producing a sandwich plate that consists of a foamed core layer and two fiber-reinforced cover layers, comprising the steps of providing a sheet of a thermoplastic plastics material, such as polyetherimide, containing an amount of a suitable solvent or blowing agent; placing said sheet between two fiber-reinforced layers of a similar thermoplastic material, such as polyetherimide; plac...

A microfabricated, tuning fork rate sensitive structure and drive electronics in which vibrational forces are communicated through a set of meshing drive (40,42) and driven (36,38) finger electrodes associated with each of two vibrating elements (18,20). The vibrating elements (18,20) are supported in a rotatable assembly (16) between first and second support electrodes (22,24) which are in turn s...

A release film for a part with a pressure-sensitive adhesive attached to the part, in which the part with a pressure-sensitive adhesive attached has adequate adhesion to the release film within the temperature range from normal temperature to a low atmospheric temperature in the winter season is provided. A release film for a part with a pressure-sensitive adhesive attached to the part, which has ...

An extrudable vinylidene chloride composition is useful in packaging films where controlled CO2 and O2 transmission rates benefit the packaging of products such as gassing cheese. The compositon, and film made therefrom, comprises 100 parts by weight of at least one vinylidene chloride copolymer; between 4 and 15 parts by weight of a plasticizer; and between 4 and 15 parts by weight of an acrylate...

A process for adhering high-melting perfluoroplastic materials is disclosed, which process comprises swelling a material comprised of a first perfluoropolymer with a solution of a second lower-melting perfluoropolymer, and then adhering the material to a substrate with an interlayer of the same second perfluoropolymer. The final assembly, as well as intermediate assemblies or compositions which ca...

The method comprises the steps of storing authorisation data in a central control arrangement (3), and transmitting (2) of index data from a computer (4), in which a certain program (6) is loaded, to the central control arrangement by device of an interface (1). The index data indicate the kind and/or the extent of the certain program loaded in the computer, and the transferred index data are comp...

The invention relates to a motor vehicle with an automatic clutch and a gearbox activated on the driver side. The clutch opens automatically when the engine speed falls short of a relatively low minimum engine speed. In certain driving conditions, in particular in the event of great differences in speed between driven and non-driven vehicle wheels, this minimum engine speed is increased.

A mineral building material, capable of foaming on water addition, consists of a cement-based reactive solids mixture, an alkali metal aluminate as pH-adjusting catalyst component, sodium perborate as gas releasing agent and calcium stearate as thixotropic agent, all the components being in solid form. A water-foamable mineral building material, in solid form, consists of (a) 70-83 wt.% Portland c...

The invention relates to a method for producing expanded polyolefin particles, according to which polyolefin granulate is impregnated with a volatile expanding agent in suspension under pressure and then relaxed. The suspension medium has a lower density than the polyolefin granulate and the suspension is practically free of suspension stabilisers.

The invention relates to a method for the production of flat structures using foamable material and fibers with a high fineness coefficient. The foamable material is applied by spinning or is foamed totally or partially thereafter on the flat structure by applying energy. Fibers with a fineness coefficient greater than 50 are used. A considerable enlargement of the active surface is achieved by us...

The invention relates to a long fiber-foam composite material, in which the long fibers are bonded to form a loose but dimensionally stable structure with good recovery properties. The long fibers are only partially bonded by foam particles in the shape of nodal points. The foamed or unfoamed foam particles are applied to the structure when the latter is being formed. The unfoamed foam particles a...
