Abstract: ABSTRACT OF THE DISCLOSURE   A carrier wave recovery circuit for recovering a carrier wave from a double-binary phase-modulated carrier wave containing a clock frequency component is disclosed.  The circuit includes a frequency doubler to which the modulated wave is applied.  A signal branching circuit passes the output through two parallel band-pass filters which derive, respectively, two components equal to twice the carrier wave frequency plus and minus the clock frequency.  These two frequency components are separately mixed with the clock frequency component which is synchronized with the modulation rate of the modulated wave and the resulting signals are combined and frequency doubled. This frequency doubled signal is combined with the output of another frequency doubler which is connected to an output of the signal branching circuit in parallel with the two band-pass filters.  A carrier wave synchronization circuit derives a synchronized carrier wave from this combined signal.  The circuit ensures that a stable synchronized recovered carrier can be obtained without the necessity for an excessive wide band frequency multiplier.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention discloses a novel apparatus for the measurement of colour of a sample which comprises an illumination means to illuminate the sample, an electro-optical sensing head to receive the light from the illuminated sample and to output electronic signals and an electronic processing unit adapted to process the signals.  The system uses, in the preferred embodiment, a moving spatial filter to modulate a spectrum and a masking means to selectively mask the light from the modulated spectrum.  A reference optical path and reference light signals are produced for subsequent processing with the light from the sample, corrected for any errors produced and processed in an analogue electronic unit to produce the tristimulus values X, Y, Z and the chromaticity coordinates x, y of the sample with respect to CIE standards for luminance and chromaticity values.  The automatic computing colour meter device is accurate, has good light throughput and has an improved signal to noise ratio.  It has wide dynamic range, fast response and automatically produces the desired results in a relatively inexpensive device.  Reference may be made to a standard source and the machine functions without the need for digital integration techniques.

Abstract: Abstract of the Disclosure An apparatus and method for use during earth boring operations when a wireline instrument  is positioned within the drill string while drilling fluid is circulated, such as during directional drilling.  The apparatus includes a cir-culating head connected to the top of the drill string that is connected to the drilling fluid pump.  A wireline sealing apparatus is connected to and extends partially into the inner passage of the circulating head.  The wireline sealing appara-tus is of the type that has a flow tube closely fitted about the wireline and in communication with grease supplied under high pressure.  The grease provides a seal while the line is stationary and while moving.  Consequently, after the wireline instrument reaches the bottom of the drill string, the wireline may be pulled upward while drilling fluid is being circulated to remove slack.  The wireline instrument also may be lowered and retrieved while drilling fluid is being circulated.

Title: Pacer demand-rate test mode control

Abstract: ABSTRACT In an implanted heart stimulating device of the demand type, test mode circuitry is arranged to cause the temporary generation of stimulation impulses at the demand-rate in the presence of naturally occurring heartbeats.  The test mode circuitry may cause dependence of the heart-stimulation rate upon the level of the power source within the test mode or at least a portion of the test mode, but is arranged to provide a heart-stimulation rate independent of the level of the power source in the ordinary demand mode.  The test mode circuitry is operative, through a relatively simple bias-modifying circuit, to force the pacer to generate at least several stimulating impulses at the demand-rate immediately following cessation of that portion of the test made in which stimulation impulses are generated at a rate dependent upon the level of the power source.  Subsequently, the pacer reverts to the ordinary (i.e., non-forced) demand mode.

Abstract: ABSTRACT     The present invention relates to the field of fluid heat exchangers.  Prior art heat exchangers cannot be readily expanded in size to handle the large volume of gas required in many applications.  Moreover, the abra-sive contaminants contained in flue gasses cause consider-able wear in some prior art heat exchangers, while in other prior art exchangers contaminants accumulate re-sulting in a reduction in handling capacity and effi-ciency.  The heat exchanger of the present invention includes a plurality of elongated, generally parallel, continuous tubes.  The lower ends or outlet ends of these tubes are rigidly secured to a platform, which platform provides vertical support for the tubes.  The upper ends of the tubes are coupled to a bulkhead which bulkhead floats within the heat exchanger frame, that is, the bulkhead is free to move in the vertical direction.  The bulkhead is coupled between an inlet transition member and the upper ends of the tubes.  Spacer sheets are dis-posed within the heat exchanger frame to assure that the elongated tubes in these sheets, thus allowing the tubes to freely expand.  Fans are mounted on the heat exchanger frame to provide a cross flow through the tubes.  The continuous, straight tubes do not significantly wear from an abrasive fluid nor do they provide surfaces where contaminants are likely to accumulate.  Moreover, these tubes may be readily cleaned.

Abstract: ABSTRACT OF THE DISCLOSURE   A re-entrable duct is provided through which a cable is adapted to penetrate a wall, e.g., of an environmentally controlled manhole.  The re-entrable duct includes a duct pipe, e.g., a length of steel pipe, through which the cable passes.  A resilient annular plug having a central aperture through which the cable passes, e.g., a so-called split rubber duct plug, is situated at each end of the duct pipe.  The annular plugs, with the duct pipe, define a sealant chamber.  A quantity of bentonite is provided which substantially fills the sealant chamber and is adapted to surround the cable.  A sleeve is secured to one end of the duct pipe adjacent one such split rubber duct plug, that sleeve including an end plate having a central aperture therethrough through which the cable passes.  The cable is thus secured within the central aperture in a cir-cumferential, hermetic sealed manner, thereby defining a secondary sealed air chamber between the splitrubber duct plug and the end plate.  Finally, a crimpable tube is disposed within, and projects from, the central aper-ture in the end plate, and is crimped into hermetically selaed contact onto the cable.  Together, the three components of the re-entrable duct seal provide a three-stage seal against moisture and at least a one-stage seal against gas.  All components can be re-entered, if necessary, and all may be placed from one end of the steel duct pipe only.

Abstract: ERROR CORRECTING SYSTEM FOR SERIAL BY BYTE DATA                 Abstract A system is disclosed for generating a plurality of error correcting check ECC bytes from a block of data presented to the system in serial by byte form.  The system employs a plurality of ECC channels which operate in parallel with the channel generating check bytes from interleaved subsets of the data block.  One channel generates an ECC parity check byte for each interleaved subset while another channel generates an ECC locator check byte for each interleaved subset of data. The ECC locator check byte for each subset represents the parity or modulo 2 sum of bit positions which are selected systematically in accordance with a predefined m sequence which is unique to each channel that generates locator check bytes.  Error patterns greater than the number of bits in one byte are correctable, as are error patterns which are less than the number of bits in one byte but extend across byte boundaries of two adjacent bytes in different subsets.
