A patterning method includes the steps of irradiating an excimer laser beam to a material layer so as to form a pattern on the material layer; and transferring onto a substrate, the material layer formed with the pattern; and irradiating the excimer laser beam to the material layer transferred onto the substrate so as to form a further pattern on the material layer.

Descaling device employing water to descale blooms, thin slabs, billets, etc., which cooperates with a mould and the zone immediately downstream therefrom, or with an induction furnace or rolling mill stands, the slabs or blooms (11-24) being fed in cooperation with the descaling device at a speed of feed of the order of 1.5-20 meters per minute, but advantageously between 4 and 10 meters per minute, the device consisting of at least one movable arm (12-13) bearing nozzle means (14) delivering d...

An adhesive fluororesin (A) comprising an ethylene-tetrafluoroethylene copolymer having at least one characteristic selected from the group consisting of a melt flow characteristic which is a melt flow rate of at least 40 and an infrared absorption characteristic which is a distinct absorption peak within a wavenumber range of from 1,720 to 1,800 cm.sup.-1 in its infrared absorption spectrum.

A method of intensifying or amplifying an image substrate obtained by imagewise release or transfer of a microcapsular substance which is liquid at room temperature, unaltered in state, by a pigment developer, and fixing the image.

A pinball game is contained within a housing which includes a liquid filled chamber. At least one ball is located within the liquid within the chamber. The ball has a specific gravity heavier than the liquid such that it tends to sink within the liquid but it is light enough to be conveyed upwardly by currents within the liquid. A flipper is located within the chamber and is capable of interacting with the ball to propel it within the confines of the chamber. The flipper is controlled by an actu...

Heat transfer apparatus comprises: (a) a heat pump, and (b) a distillation means operatively connected with the heat pump to receive distillable fluid therefrom for condensation and release of latent heat Q.sub.c, (c) the heat pump connected with said distillation means to receive said latent heat for addition of work input and re-transfer to the distillation fluid.

An antenna is for a wireless communication device mounted in an opening of a wall. The antenna includes a switch cover plate adapted to cover the opening of the wall. The switch cover plate includes a first or front surface adapted to be disposed away from the opening and an opposite second or rear surface adapted to face the opening. An antenna element, such as a dipole or loop, engages the front surface of the cover plate or is disposed between the front and rear surfaces. A connector is elect...

A measurement system includes a transceiver and a transponder. The transceiver is configured to send and receive radio frequency signals. The transponder is configured to receive radio frequency signals from the transceiver and to send radio frequency signals to the transceiver. The transponder includes a sensor. The transceiver is configured to send an activation signal to the transponder thereby enabling the first transponder sensor to make a measurement and to hold the measurement.

The present invention provides a method for inhibiting fouling deposits in refinery processing equipment caused by the heat treatment of hydrocarbon feedstocks. The deposits are inhibited by adding to the feedstock an effective amount of an iron sulfide dispersant prepared in accordance with this invention. The dispersants comprise polyimides which are prepared by reacting fatty amines with maleic anhydride/alpha-olefin copolymers.

A game has a plurality of playing pieces and a plurality of stacked disks. Each of the disks is pierced by an angularly spaced plurality of peripheral apertures. At least one of the apertures in each of the disks is sized to allow passage of the playing pieces. An entrapping one of the apertures in each of the disks is shaped to prevent passage of the playing pieces. These disks are interconnected to rotate relatively and coaxially. Each of the disks has its apertures alignable of those of adjac...
