Abstract: An electrically grounded storage cabinet (20) for electrical circuit board modules (15) provided with multiple rectangular arrays of brackets (100, 108, 130, 160) for receiving at least one pair of conductive rectangular shelves (180). The shelves (180) are slidably adjustable in elevation relative to each other on the brackets. A circuit board module (M) is received between registered grooves (182, 189) in the lower surface of one shelf and the upper surface of the other shelf in each pair. The modules are grounded through the shelves, supporting brackets, and cabinet wall (22, 24, 26, 28, 30) to preclude damage to the modules from static electricity discharges and to provide a controlled discharge of any charge remaining in circuit board components after removal from service or any incoming charge from personnel or the environment.

Granted: 1991-11-27
Abstract: An apparatus is provided that is useful for effecting liquid-liquid extraction by contacting a first liquid medium with a substantially immiscible heavier second liquid medium. The apparatus includes either a single mixer-settler unit or two or more such mixer-settler units in series. Each mixer-settler unit includes a vertically extending settling tank. An elongated extraction column extends generally vertically upwardly through the settling tank bottom. The extraction column is open at its top with the top of the extraction column below the top of the settling tank. A mixer is provided in liquid communication with the extraction column for mixing the first and second liquid mediums together to form a dispersion of droplets of one of the liquid mediums in the other liquid medium and for pumping the liquid mediums through the apparatus. The dispersion flows from the mixer upwardly through the extraction column and out from its top into the settling tank. The first liquid medium separates from the dispersion, rises to the top of the settling tank and exits the settling tank from an outlet near the settling tank top. The second liquid medium separates from the dispersion, sinks to the bottom of the settling tank and exits the settling tank from an outlet near the settling tank bottom.

Granted: 1989-10-18
Abstract: During off-peak hours, mechanical energy is stored by pumping liquid from a first cavern into a second cavern containing a gas. In this way the gas in the second cavern is compressed. The stored energy is recovered by allowing the gas in the second cavern to expand, which causes liquid to flow-back from the second to the first cavern. The liquid flowing back from the second to the first cavern is used for driving a turbine.

Abstract: A fiber-optic system for measuring a desired environmental parameter, such as temperature, is disclosed. The system includes a fiber-optic sensing head that alters light of a prescribed frequency as a function of the environmental parameter to be measured. Light not of the prescribed frequency is not so altered. In a preferred embodiment of the fiber-­optic sensing head, a semiconductor material is positioned between two substantially parallel optical fibers at a distal end of the fibers. One fiber serves as in input channel and the other fiber serves as an output channel. Both fibers approach the semiconductor material from the same direction. Light channeled to the semiconductor material is reflected at the distal end of the input fiber so as to pass through the semiconductor material, and then is reflected again at the distal end of the output fiber so as to pass back out the output fiber. The semiconductor material absorbs the light of the prescribed frequency as a function of temperature. By monitoring the intensity of the light of the first frequency at the output channel, a measurement of the temperature to which the fiber-optic sensing head is subjected can be determined. To remove the influence of input light intensities, fiber attenuation, and the like, from the temperature measurement, lights of two frequencies, only one of which is the prescribed frequency, are selectively directed to an optical detector through the fiber-optic sensing head and through a separate fiber-­optic reference channel. The four measurements thus obtained at the optical detector -- prescribed frequency through sensing head, prescribed frequency through reference channel, non-prescribed frequency through sensing head, and non-prescribed frequency through reference channel -- are appropriately processed in order to generate a signal that has all variations or influences removed therefrom except the temperature variations of the sensing head.

Date Jan. 29, 1987.A wafer scale integrated circuit comprises a few hundred modules (10) which can be connected into a long chain by commands sent to the modules along a transmit path set up by way of module inputs (XINN, XINE, XINS, XINW) from neighboring modules and outputs thereto (XOUTN, XOUTE, XOUTS, XOUTW), only one of which is enabled by one of four selection signals (SELN, SELE, SELS, SELW) acting both on transmit path logic (20) and on receive path logic (21) in a return path. Each module includes configuration logic (22) which decodes commands providing the selection signals (SELN, etc), a READ signal and a WRITE signal. The configuration logic (22) is addressed when a bit is presented thereto by the transmit path simultaneously with assertion of a signal (CMND) which is supplied globally to all modules. The address configuration logic clocks the bit along a shift register and the selected command is determined by the position of the bit at the time that the global signal (CMND) is terminated. Each module includes am memory unit (23) including a free running address counter. When the WRITE command appears a data stream on the transmit path is read into the memory. When READ appears, the contents of the memory are read out onto the return path. Memory refresh occurs conventionally under control of the free-running address counter. In order to avoid heavy current in any of the power distribution conductors on the wafer, the count cycles of the free-running address counters are staggered.

Abstract: Printed circuit boards containing thru-holes requiring metallization are manufactured by first applying to the board material an alkaline strippable resist in a predetermined desired pattern, thereafter applying material catalytic to subsequent metallization, thereafter treating the board with an aqueous alkaline solution to remove catalytic material from resist surfaces without adversely affecting the catalyst at non-resist areas, and then metallizing the non-resist areas. The ability to preliminarily apply the resist pattern before catalyst application, metallization, etc., yet prevent metallization of the resist, enables the manufacturing process to proceed straight through the activation, metallization, etc. steps without need for interruption for resist application.
