A method for atomizing a liquid which comprises the steps of 1) forming a dispersion of minute gas bubbles in a flowing enclosed pressurized liquid, said liquid and gas being the continuous and dispersed phases respectively, and 2) subsequently forcibly expelling the dispersed system through an hydraulic atomizing nozzle into an ambient atmosphere to provide an expanding stream of minute droplets. The preferred apparatus for carrying out the method of the invention is a venturi tube fitted at on...

A method and apparatus for the continuous production of welded tube from a continuous length of strip material wherein the welded seam is cold worked and wherein the physical nature of the welded seam is continuously monitored to insure that a proper weld is produced is described herein.

An improved grouting method and arrangement using particulate material and aqueous solutions of alkali silicate materials confined between pile seal assembly and top of an offshore platform in sealing the annular space formed between either a jacket leg or pile sleeve and a pile driven therethrough or similar annular space of an offshore platform to support a column of grout thereon so that the annular space may ultimately be filled with grouting material.

The invention provides for controlling the after grinding size of a work piece and the production rate while maintaining surface integrity and finish of the work piece substantially uniform. The method includes the step of controlling the surface velocity of a grinding element to maintain the specific grinding energy substantially constant.

Improved performance of known techniques of spraying liquids to form extremely dense liquid sprays or aerosols can be obtained by pre-saturation of the carrier gas at a given location before final introduction of the product to be aerosolized into the spraying system.

A wire from each of two communication cables to be spliced is inserted into a tang connector, which has a stiff plate above and below the connector. The tanged connector is one of many in a block. The connectors, each containing wire, are crimped by forcing each connector into a tapered hole, the plurality of tapered holes being located in a crimp block. After crimping the connectors, the excess wire is cut off by a cutter in a slot in the crimp block. The crimp block is left permanently attache...

There is disclosed the use of synthetic organic reactive polymer resins and other materials as soldering fluxes. These resins contain "chemical functionalities", i.e., radicals therein which provide active hydrogen for removing the oxides from the metal substrate during the soldering operation. There are essentially three types of applications as follows. The materials, distinct from known rosin fluxes, do not harden and may be easily removed with solvents. The chemical functionalities may be su...

A narrow beam of light is directed through an optical chamber to intersect a thin stream of small particles to be optically analyzed. At least two photoresponsive pick-up elements are positioned at different angular positions with respect to the beam to simultaneously detect different optical reactions of each particle to the beam illumination.

A printing method wherein a series of indicia, a geometric design, an artistic work or the like is scribed on a flexible plastic sheet serving as a printing plate. The plastic sheet is then coated with a water base ink, an oil base ink, or both, one after the other in either order. The excess ink is removed after each coating. The inked plastic sheet is placed on top of an ink receptive paper or the like with the scribed and inked surface of the plastic sheet adjacent the paper. The non-scribed,...

An illustrative embodiment of the invention converts a signal that reflects the natural radioactivity of an earth formation into another signal that is related to the volumetric shale fraction of the formation under observation. Typically, the radiation signal is normalized to a standard formation radioactivity characteristic. The normalized signal then is contrasted with some other physical parameter (e.g., porosity, density) in accordance with the specific mineral composition of the formation ...
