Title: Stationary drill string hydraulic mining tool  apparatus
Inventor: HODGES EVERETT L

Abstract: STATIONARY DRILL STRING HYDRAULIC MINING TOOL APPARATUS             ABSTRACT OF THE PRESENT INVENTION      An improved hydraulic mining tool apparatus for the recovery of minerals from subterranean formations is dis-closed wherein the drill string, which extends from ground surface into the mineral deposit, is adapted to be main-tained stationary during the mining operation while the mining tool, mounted to the lower end of the drill string, is adapted to rotate within the mineral formation.  By maintaining the drill string stationary within the forma-tion, frictional drag forces and tortional forces exerted on the apparatus are minimized thereby substantially reducing the input power requirements and reducing the possibility of a twist-off of the mining tool within the formation.  The present invention additionally discloses a multiple stage slurry transport system for increasing the recovery rate of mined minerals from deep subterranean formations and further includes a tri-cone cutting bit attachment, mountable to the lowermost end of the mining tool which provides a rock crushing and force-feeding effect of mined materials into the mining tool.

Abstract: ABSTRACT A separable fastener is provided, consisting of a male member with a stem portion and a T-shaped head portion, and a female member in the shape of an elongated body having a tail portion and a forward portion that is bent with respect to the tail portion. The body has an opening adjacent the bent portion, the opening of sufficient length to permit insertion of one arm of the T-shaped head portion of the male member. The bent forward portion of the female member terminates at an edge which interferes with complete passage of the T-shaped head portion through the opening in any but one particular orientation of the male member with respect to the female member.  The edge has an indentation which is adapted to receive the T-shaped head portion when the male member is in that particular orientation, thus permitting the avoidance of interference and a complete passage of the T-shaped head portion through the opening.  The opening also has a part wide enough to permit swivelling of the stem portion of the male member after passage of the T-shaped head portion through the opening.

Abstract: APPLICATION OF    T. B. BOZARTH, A. M. DEMARK, E. F. FINN AND F. LYNCH                SENSOR COMMUNICATION SYSTEM          ABSTRACT    A sensor communication system uses a shared analog signal to duty cycle converter for producing a comparison between a predetermined free-running triangular waveshape and a selected output signal from a plurality of analog signal sources such as process sensors, to convert the amplitude of the analog signal to a variable duty cycle signal.  The variable duty cycle signal is subsequently converted to a digital signal which may be represented by a count stored in a counter counting clock pulses during the occurrence of the pulse width waveshape of the variable duty cycle signal.  The digital signal is utilized as a digital word by a microprocessor operating in accordance with a stored program to produce a characterized digital output signal for use in a communication after conversion to a 4-20 ma control signal for communication and control in an industrial process control system.  One of the signal sources may be from a circuit having temperature and time drift components whereby the corresponding digital word is used by the micrcoprocessor to compensate the digital words from the other analog signal sources.

Abstract: Abstract In a television receiver, a horizontal peaking signal produced by a peaking signal generator is added to a luminance signal to accentuate its horizontal detail. The peaking signal is subject to a coring action from a control voltage source with the amount of coring subject to dynamic control as a function of luminance signal content.  The sense of coring control is such that a greater amount of coring is associated with dark portions of a scene to be reproduced than is associated with bright portions thereof.  The coring control is non-linear and exhibits one control characteristic over a first range of luminance signal levels between a white image limit and a threshold level in the black image direction, and a different control characteristic over a second range of signal levels between the threshold level and the black image limit for restricting the amount of coring produced as the black limit is approached.

Abstract: Abstract of the Invention An anchor bolt assembly includes a sleeve-like expander made of a resilient material, an end plate attached to the distal or inner-most end of the expander, a flange mounted on the proximal or outermost end of the expander, and a fastener.  In use, the assembly serves to anchor an object to a substrate, such as a wall.  The fastener is inserted through a longitudinal opening in the expander and threadably engages the end plate in order to apply an axial compression force to the expander, which force causes the resilient expander to bulge outward to contact the inside surface of an opening in the substrate.  This longitudinal compression and transverse expansion of the expander causes the assembly to be securely anchored in the substrate opening.  The flange provides a wide base against which the axial compression force generated by the fastener and end plate can act.  In one embodiment, the flange is integral with the resilient expander, while in a second embodiment the flange is non-resilient to provide additional support to the fastener and prevent the cold flow of the expander material. Advantageously, the anchor bolt assembly is reusable and can be utilized in conjunction with a wide variety of substrate materials and thicknesses.     GA-2620:ks1/dd2

Abstract: REAL TIME DATA TRANSFORMATION AND TRANSMISSION OVERLEAP DEVICE                              ABSTRACT A real time data transformation and transmission apparatus transforms data from a first data device and transfers the transformed data to a second data device which need not have a data transfer rate consistent with the first data device.   Data from the first data device is divided into blocks and is compressed by a compression device and written into a buffer. A controller controls the buffer to transmit compressed data to  the second data device as a function of the data receiving rate of the second data medium provided that the buffer contains a predetermined amount of data.          While the buffer is transmitting data, the compressor is compressing further blocks of data which are being written to the buffer such that the predetermined amount of data is stored in the buffer upon completion of the buffer transmitting a block of data.   This ensures that complete blocks of data are transmitted to the second data medium at the data receiving rate of the second data medium.
