Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed are gas fed, porous electrodes capable of steady, high current density operation for practical periods of service, e.g. as oxygen cathodes in metal-air batteries.  The subject electrodes feature at least two bonded composite layers, one of which is a form-stable, conductive wetproofing layer while the other is an unusually thin active layer containing active carbon particles predominantly between about 2 and about 20 micrometers and having a high internal surface area, e.g. a B.E.T. surface area of over 1000 m2/gram.  A simple and highly successful method of preparing such electrodes is also disclosed, which avoids the necessity of separately forming and handling the thin active layer.

Abstract: ABSTRACT OF THE DISCLOSURE     A chip implemented in new technology is designed to include expandable levels of new functionality.  The chip includes compatibility circuits which connect to a number of pins which are unused in the chip it replaces in an existing computer system.  The compatibility circuits connect to those internal parts of the new chip that contain the newly added or altered levels of functionality.  The new chip is installed in the existing computer system just as the prior chip.  When so installed, the compatibility circuits enable the new chip to operate in the same manner as the replaced chip but at high speed and with improved performance.          When the new chip is installed in the system for which it was designed, the compatibility circuits enable the chip to operate with a selectable level of new functionality at the same higher speed and improved performance.

Abstract: MULTIPLE ZONE OIL RECOVERY PROCESS     Abstract Viscous oil is recovered from a subterranean reservoir having two or more vertically separated oil bearing, permeable zones separated by impervious layers such as shale.  A steam drive process is employed in each permeable layer, using ordered patterns of injection and production wells with the pattern in each layer staggered with respect to the pattern in the adjacent layer or layers.  The injection and production wells are singly completed. The use of staggered well patterns in this manner produces a greater recovery of oil at an earlier time than a regular, superimposed pattern of wells in each layer.

Abstract: ABSTRACT OF THE DISCLOSURE      For severing a continuous slide fastener chain into individual slide fastener lengths, the chain having succesive coupling element portions and element-free gap sections on a stringer tape, a cutting station is preceded by a detecting unit.  The detecting unit utilizes at leasat two sensors for sensing the leading end of each successive coupling element portion of the chain which is being conducted to the cutting station. The sensors are longitudinally spaced along the chain's path to the cutting station and produce respective command signals one after the other to a chain drive to reduce the moving rate of the chain in step fashion to a low speed as the gap section approaches the cutting station.  This enables uniform and adequate quality fastener length cutting to be reliably achieved.

Abstract: ABSTRACT      A portable spectrum analyzer using frequency synthesis is used in the field to perform voltage amplitude measurements of specified channel segments in a multichannel configured coaxial cable environment.  The instrument is a microprocessor (28) based system, and includes an RF input (1) and keyboard (36) and function switch inputs and provides both aural and visual outputs by means of a speaker and an LCD display (27).  A three stage frequency converter (7) including PLLs (11, 12 and 13) controlled by the microprocessor (28) allows for the automatic monitoring of a plurality of carrier channels or the display of both video and audio levels of a single channel.          Automatic adjustment of the input signal level is provided by attenuator pads (2 and 3) controlled by the microprocessor (28).  Calibration is also automatically controlled by the periodic injection of a signal of predetermined level from a noise source (4) under the control of the microprocessor (28).  The microporcessor is programmed to provide several modes of operation including a sweep mode, a zoom mode, and a memory mode.  In the sweep mode, the instrument continually scans all carrier channels automatically, each channel being presented sequentially and simultaneously in bar graph form on the LCD display (27).  In the zoom mode, a single channel is displayed with both video and audio levels side by side.  In the memory mode, the operator can view data saved from measurements previously made at a selected location in the cable system.

Abstract: METHOD AND APPARATUS FOR OPHTHALMOLOGICAL SURGERY     ABSTRACT OF THE DISCLOSURE     The invention contemplates use of a scanning laser characterized by ultraviolet radiation to achieve controlled ablative photodecomposition of one or more selected regions of a cornea.  Irradiated flux density and exposure time are so controlled as to achieve desired depth of the ablation, which is a local sculpturing step, and the scanning action is coordinated to achieve desired ultimate surface change in the cornea.  The scanning may be so controlled as to change the front surface of the cornea from a greater to a lesser spherical curvature, or from a lesser to a greater spherical curvature, thus effect-ing reduction in a myopic or in a hyperopic condition, without resort to a contact or other corrective auxil-iary lens technique, in that the cornea becomes the corrective lens.  The scanning may also be so controlled as to reduce astigmatism and to perform the precise incisions of a keratotomy.  Still further, the scanning may be so controlled as to excise corneal tissue uniformly over a precisely controlled area of the cornea for precision accommodation of a corneal transplant.

Abstract: SYNTHETIC PEPTIDE-BASED ANTI-RABIES COMPOSITIONS AND METHODS                         ABSTRACT        A sequence in the coat glycoprotein of rabies virus is identified as the molecular basis for an essential step in the pathogenesis of the virus, the binding of virus to acetylcholine receptor at neuromuscular junctions prior to virus uptake into peripheral nerves.  Based on this discovery, synthetic peptide-based, anti-rabies vaccines are prepared.  The active ingredient of such vaccines is a synthetic protein, which is a conjugate with an immunogenic carrier protein of a synthetic peptide with a sequence which includes a sequence which is substantially the same as a substantial portion of the sequence of the acetylcholine receptor-binding segment of the rabies virus coat protein.  Anti-rabies antisera, and anti-rabies antibodies, are prepared by injecting a mammal with a synthetic protein of the invention in a manner that induces an immune response in the mammal against the synthetic protein.  Hybridomas which secrete anti-rabies antibodies, which bind to specific epitopes on or near the acetylcholine receptor binding segment on the rabies virus coat glycoprotein, are prepared with B cells immunized in vitro with a synthetic peptide or synthetic protein of the invention or taken from a mammal inoculated with such a peptide or protein. The anti-rabies vaccines of the invention avoid risks associated with currently available anti-rabies vaccines.  The antisera and antibodies of the invention are useful therapeutically to induce passive anti-rabies immunity in a mammal that has been exposed to rabies virus.  The antisera and antibodies are also useful for diagnosing whether a mammal is rabid and whether a mammal has been exposed to live rabies virus.

Abstract: Abstract of the disclosure ERROR DETECTION USING VARIABLE FIELD PARITY CHECKING      A variable number of parity bits or error correction code per word is used to increase error detection for words having the extra parity bits in a control store.  Since some words do not utilize all the architected space available for words, extra parity bits are generated at development time for such words and stored with the words.  A decoder identifies the location and number of parity bits.  Parity checking against the extra parity bits is then performed on different groups of bits in the word.  This provides an inexpensive means of increasing error detection with minimal hardware cost.

Abstract: A process for stabilizing soils, for example fine-grained earth or clay, by using vacuum pumping to provoke settlements in the soil comprises the development of vertical drainage holes, which are coupled to suction pumps for the evacuation of drainage water, and the generation of underpressure in a region of the soil covered by an airtight tarpaulin, which, at its edges, is sealed against the soil, the atmospheric pressure contributing to the said settlements. The soils are first frozen to form ice crystals, which grow by water being drawn out of the soil/clay between the ice crystals, the ice crystals exerting a consolidating pressure on the mineral grain aggregates of the soil. The frozen region is rethawed by the supply of heat, after which excess water is drawn out of the soil and drainage holes by vacuum-pumping in order to provoke the said settlements, whereupon the region will appear as a depression. <IMAGE>
