Abstract: LINEAR CODEC WITH DUAL DIVIDER            Abstract Disclosed is a charge redistribution codec employing a two capacitor network for developing a progression of reference voltages having a binary relationship to each other for each analog input sample to be encoded.  Linear encoding of input samples is achieved with the use of two such charge  redistribution networks, with one developing positive reference voltages and the other developing negative reference voltages.  Analog input samples are placed in an encoding capacitor and based on the polarity of the voltage across the capacitor either a positive or a negative charge is added iteratively to the capacitor in the direction of driving the voltage across that capacitor to zero. A code is developed by assigning at each iteration one value to an output code bit when a positive voltage is added and the opposite value to the bit when a negative voltage is added.         Chord-law encoding is achieved in a similar manner except that the output code includes a sign bit, a chord count and a linear code for describing the signal within the chord.  Operationally, as with linear encoding two reference voltage generating circuits are employed to provide the positive and negative reference voltages.  In addition, means are provided for adding an offset voltage to increase the magnitude of the input sample for assigning a sign bit based on the initial polarity if the input sample and for chord counting.

Abstract: DUAL-ANTENNA TRANSCEIVER                        ABSTRACT           A magnetic-field, noise-cancelling transceiver is provided by a dual-coil antenna circuit.  In the receive mode, two identical coils, connected in series opposition, cancel noise signals common to both coils and receive desired signals present at only one coil.  Capacitance in parallel with the series-opposed coils establishes the resonant frequency of the receiver, antenna circuit.  In the transmit mode, the two coils, connected in series opposition, have their non-adjacent terminals clamped to ground via two pairs of oppositely-poled diodes, one pair on each non-adjacent terminal.  The transmitter signal, coupled to the junction of the two coils through a capacitor, generates additive magnetic fields by causing equal currents to flow in each coil from the common junction, to their respective diode junctions, to ground through the respective, oppositely-poled diode pairs. Series resonance is established by the transmitter coupling capacitance and the parallel combination of the two coils.  The transmitter and receiver tuning are independent.  The receiver tuning is unaffected by the transmitter circuitry and coupling capacitance because the transmitter is connected to the null between the receiving antenna coils.  The transmitter tuning is unaffected by the receiver circuitry and receiver capacitance because the diode pairs provide a relative short across the receiver input during transmission.

Abstract: Abstract of the Disclosure Diverter apparatus for rapidly and gently diverting articles, typically fruit, from a moving conveyor.  The apparatus comprises an ejector lever member, an air cylinder assembly, and a stationary ejector lever mount, the two former sharing a common pivot point while each of the two is pivotable with respect to each other while pivoting on pivot pins mounted to the stationary mount.  The working end of the ejector lever is caused to swing arcuately over a certain distance to divert the fruit when the piston rod of the air cylinder assembly travels a much shorter distance, thus permitting very rapid cycling of the diverter.          Diverting and retraction strokes of the piston are controlled by air from a solenoid valve, the solenoid valve receiving control signals from a computer controlled relay.

Abstract: ELECTROGRAPHIC SYSTEM AND METHOD     ABSTRACT OF THE DISCLOSURE   An electrographic system and method having a control which carries out correction for graphic surface non-linearities. The control employs a procedure wherein a correction look-up table is developed as part of the manufacture of the device wherein output readings are taken along a physical domain rectangular grid array of predetermined dimension and these output readings are adjusted in their signal domain to establish a regularly incremented sequence of address values within that signal domain. Physical domain coordinate values then are derived and placed in the table for each address value. The control then accesses this memory for each of a given locator or tracer position on the graphic surface and carries out an interpolative weighting to derive acceptably accurate coordinate pair signals which are outputted to a host computer or the like.

Abstract: ABSTRACT         A fiber optic rotation rate sensor employs two fiber loop interferometers.  Two Sagnac fiber optic interferometers are interleaved such that both fibers are contained in each each interferometer.  A coherent light beam at one frequency is proprogated in only one of the fibers, and an optical beam at another frequency is proprogated in the other fiber.  The beam emerging from one of the fibers is combined with the beam emerg-ing from the other of the fibers for each of the two ends of each fiber to produce a pair of interference signals each having a frequency equal to the difference between the two light beam frequencies.  The relative phase of these two signals is then determined to pro vide an indication of the rate of angular rotation of the fiber optic loops, and this determination is inde-pendent of any temperature-related characteristics that produce offset phase errors.

Abstract: ROGERS, BERESKIN & PARR     TITLE:  IMPROVED METHOD FOR ROCK REPRODUCTION          INVENTOR:  PHILIP DI GIACOMO     ABSTRACT OF THE DISCLOSURE     This invention relates to improvements in methods for reproducing natural rock surfaces which are used as decorative faces for walls, facings, shorelines and the like.  A rock surface to be reproduced is coated with latex and the latex is then coated with urethane resin to form a mold panel.  The mold panel is removed from the rock sur-face and its inside is coated with a thin layer of sprayed concrete to form a concrete rock panel.  The rock panel is removed from the mold panel and is used to form a cast-in-place reproduced rock wall.  Tha concrete rock panel so formed is of sufficient strength to maintain its proper profile while concrete is poured behind it.  Because of the concrete rock panels strength and rigidity, it can be read-ily supported in place by a simple framework.           In the case of larger surfaces mold panels can be made of various portions of the natural rock surface, and trimmed along natural issures.  The corresponding rock panels formed from the mold panels can be overlapped and the edges grouted together to reproduce the entire natural rock surface. The joins are substantially invisible since they occur along the fissures.

Abstract: X-RAY-EMITTING INTERSTITIAL IMPLANTS             ABSTRACT OF THE DISCLOSURE        Particles or "seeds" are manufactured for implantation into tumors within a human body for emitting X-rays to destroy or reduce the tumors.  The seeds contain palladium which is substantially enriched in palladium-102 and which is activated by exposure to neutron flux so as to contain a minor, but significant, fraction of X-ray-emitting palladium-103.  The palladium is distributed on or throughout a base material so as to reduce self-shielding by the palladium.  The seeds include an X-ray-opaque marker to faciliate external visualization of the seeds after their implantation, the marker preferably being formed of a material, such as lead or rhodium, which does not activate to contain undesirable isotopes under the radiation conditions in which palladium-102 is activated to palladium-103.  The base material-distributed palladium and the marker are encased in an elongated shell which is formed by welding a pair of end caps to a tubular member, the construction of the shell reducing the mass of material at the end of the seed, thereby providing a more isotropic angular distribution of X-rays.
