Abstract: ABSTRACT OF THE DISCLOSURE      Temperature-sensitive instruments and methods for produc-ing them are disclosed.  The apparatus disclosed comprises a pair of temperature-sensitive sensors which have at least one electrical property, such as resistance, which varies with temperature, and which are in electrical communication with each other, conductors connected to these sensors so that the temperature-sensitive instrument can be employed to provide a temerature reading by determining that electrical property from the conductors, and where the electrical property of each of the sensors has equal and opposite deviations from predeter-mined values so that the sum of those deviations approximately equals zero.  In a preferred embodiment the sensors are coupl-ed in series.  The method disclosed includes measuring an electrical property of a plurality of these temperature-sensitive sensors, which preferably are thermistors, sorting the sensors in accordance with the measured values of that electrical property, selecting a plurality of the sorted sensors so that the sum of the deviations from predetermined values of the measured values of their respective electrical properties is approximately equal to zero, and assembling those selected sensors into a temperature-sensitive instument.

Abstract: ABSTRACT          Apparatus for detecting and providing a signal from detection indicia carried by a controlled document for determining its character, the document passing through the apparatus at high speed, the detection indicia being substantially more conductive than the substrate.        Detection is effected by establishing a capacitive element with the aid of a charging electrode passing relative to the detection indicia and in such passage inducing a capacitive charge onto the detection indicia, movement of the charged detection indicia relative to a sensor electrode downstream establishing a second capacitive element.  The charge remaining on the detection indicia moving into juxtaposition relative to the sensor electrode, tends to leak off through coupling with this sensor electrode.  The leakage current is used to provide a signal whose amplitude is detected and to operate certain output means such as indicators, ejectors, counters, or the like which will respond in accordance with the character of the detection indicia, for example, its size.

Abstract: ABSTRACT     Pathological tissue is excised with a beam from a laser that is coupled through a flexible, optical waveguide to a collimator that reduces the beam cross-sectional area by variable, controlled amounts.          A transparent bore or a graphite cannula couples the beam exiting the collimator to the tissue to vaporize same.  An electrically responsive deflector gyrates the reduced cross-sectional area beam about a bore sight axis aligned with the cannula bore so that the excised tissue has a frusto-conical volume.  To excise different, displaced tissue regions, a position servo system moves the cannula so the bore sight axis moves in a plane at right angles to a plane on the exterior surface containing the pathological tissue.

Abstract: ABSTRACT OF THE DISCLOSURE        A system for detecting the direction of speech transmission between a telephone communication device and a telephone line connected thereto comprises an apparatus for detecting coincidence in the phase of speech signals developed across respective impedances and an impedance network by means of which said device is coupled to the telephone line.  The apparatus for detecting the phase coincidence of the signals comprises a pulse generating device for generating trains of pulses in response to excursions of the respective signals across a reference level, and a gating device responsive to the coincidence of pulses of the respective trains.  In a system with separate amplification of talk and listen channels, the amplifier providing the output to the line is preferably an operational amplifier connected to have substantially zero output impedance, which makes possible a simple configuration of an impedance network of which respective impedances are effectively connected either in series or in parallel, in accordance with the direction of speech transmission.  Such impedance network thus provides for the appropriate change in the phase relationship of signals developed across the respective impedance.

Abstract: ANATOMICALLY MANIPULABLE ROTATABLE IMPLEMENT An anatomically manipulable toy in the form of a rotatable implement comprising a shaft, a massive body portion rigidly attached to the shaft, and a contact element at one end of the shaft. In operation, the rotating implement is generally supported by placing the contact element on a portion of the user's anatomy, typically a hand, with the shaft horizontal, rotation having been initiated by manually imparting a torque to the implement, typically at the shaft. The contact element rolls on the user's anatomy, thereby producing a linear translation therealong. The weight of the implement acting at a horizontal separation from the point of contact causes a precession of the spinning implement about the vertical axis through the point of contact. The rate of precession depends on the rate of angular rotation and the distance of horizontal separation. Thus, the rotating implement precesses at a controllable rate relative to the rate of linear translation, allowing the implement to circumscribe a portion of the anatomy such as the palm, or travel along the arm as the user rotates the arm. The dimensions and mass distribution of the device are characterized by three dimensional parameters, namely the radius of gyration R, the axial distance L between the center of gravity of the device and the point of contact between the contact element and the user's anatomy, and the diameter D of the contact element. the quantity L/(R2D) is preferably in the range of 0.05 - 0.11 reciprocal inches squared (hereinafter sometimes inch-2).
