This is a method to connect two or more drill holes, such as drill holes at distances of 2,000 to 5,000 feet or more apart, for the purpose of producing soluble ores, such as sylvanite or carnallite, from thick, deep ore bodies or from thin, shallow ore bodies. The drill holes are connected utilizing a signal-sending...

A rugged portable diagnostic apparatus is configured for temporary installation and operation on board Naval ships. The apparatus provides gunnery training support by allowing a comprehensive empirical assessment and feedback of individual, team and equipment performance on an economical and environmentally...

A mowing apparatus including a casing containing a cord and operative to rotate while an end portion of the cord is drawn out therefrom. The casing is formed with a cord outlet opening in the form of a slot having a major axis oriented in the direction of rotation of the casing.

A semi-submersible vessel is disclosed in which a side wall which is continuous in the horizontal direction connects an underwater buoyant pontoon hull to an operating deck located above the water surface. In operation the side wall is subject to moderate cyclic fatigue stresses only, thereby increasing the useful...

A pager arranged for operation in a cellular radio system provides economy to subscribers and technological flexibility to a system operator. Paging service is available in any geographical area covered by the advanced mobile phone service system. Subscribers are thereby able to travel at will while continuing to...

An analog transversal filter includes a charge transfer delay line, including a plurality of cells for storing electrical charge, and a multiphase clock to transfer electrical charge from cell to cell through the delay line. A plurality of injection electrodes are connected to predetermined ones of the cells to sample...

Multiple phase flow is detected and characterized in a fluid-containing conduit using a compressional wave acoustic transducer in the pulse-echo mode. The acoustic energy is transmitted in a transverse direction through the conduit and the returning echo is analyzed to determine if single or multiphase flow is present...

An addressable delay memory device which operates as a dual mode device. In he first mode, the addressable delay memory functions as a first in-first out delay memory in which the data is delayed for a predetermined period. In the second mode, the addressable delay memory operates under the control of a remote...

A pressure sensor assembly (10, 10') is disclosed in which a pressure sensing element (11, 11', 11") is protected from external contaminants in an externally-applied pressure (P) to be sensed. This is accomplished by filling an external cavity (36) of a tubular portion (32) of a cover member (30) which fits over the...

A phased array antenna is disclosed including a central reference element. This is surrounded by a plurality of sub-elements which form the adaptive elements of the array and have no feed networks. Each adaptive element is essentially an "L" stub, with the adaptive elements oriented such that the "L" top loading is...
