Abstract: INSERT MEMBER FOR A HELICAL DISPENSING COIL     ABSTRACT OF THE DISCLOSURE    In a dispensing machine of a helical coil type having a plurality of shelves which each contain at least one elongated helical dispensing coil, an insert member is received inside the convolutions of selected coils.  Each insert member comprises a plastic rail member having a bracket at one end.  The bracket loosely and nonrotatably journals the insert member about the shank of the output shaft of the motor for the coil.  The insert member extends forwardly through the coil to a position between the last and next to last convolutions of the coil.  The insert member is free floating relative to the coil by virtue of its mounting and rides on the inner surfaces of the lower-most portions of the convolutions of the coil.  Rotation of the coil imparts a rocking movement to the insert member.  Thus, the insert member supports the products received in the coil above the shelf surface and further agitates these products to prevent their sticking to the insert member.

Abstract: ABSTRACT OF THE DISCLOSURE         In an optical measuring device for measuring physical magnitudes a sensor is actuated by the physical magnitude to be measured.  An optical signal generator and processor provides light signals to the sensor and processes optical output signals transmitted from the sensor.  Optical fibers conduct light to the sensor and transmit light signals therefrom to optical detectors.  The sensor modulates at least a portion of the light transmitted thereto such that the modulated light output therefrom transmitted to the optic processor contains measuring components representative of the magnitude to be measured and stabilizing component signals independent of the magnitude.  The optical processor separates the measuring components and the stabilizing components and generates at least one measuring signal and compensating signals for stabilizing the measuring device.

Abstract: METHOD AND APPARATUS FOR FORMING HIGH RESOLUTION HALFTONE IMAGES                        ABSTRACT          Halftone images are formed from dots selected from a dot character font memory storing information representing halftone dots of different sizes and shapes corresponding to different gray scale tone values or image densities.  An orig-inal image is first scanned to sample its tone values at minute intervals exceeding the desired dot resolution of the reproduction.   These sample values are digitized by an A/D converter which converts them to multibit binary numbers.          Adjacent samples are compared to determine the average image density in a particular area, as well as the rapidity of rate of change of image density within that area.  If the rate of change of image density in a given area is below a selected threshold value, the area is designated as low detail and the multibit binary number representing the result of the average density calculation over the area is used to select a dot character from the font memory for reproducing that area of the image.  If, however, the rate of change of image density exceeds the selected threshold value,  indicating an area of relatively high detail, the area samples are used to select special dot shapes and positions for use in reproducing that sampled area.  This technique achieves a higher resolution halftone image for a given amount of stored data than prior techniques, as well as achieving a higher "apparent" resolu-tion to the observer.

Abstract: 3.9.1979                   1                   PHN 9235 ABSTRACT:   Method of and device for providing a concentric envelope on an end of all optical fibre, and fibre end provided with an envelope in accordance with the method.           The invention relates to a method of and a device for providing on outer surface of an envelope, being concentric to a light-conductive core, around a mono-mode optical fibre; this means that the eccentricity of the fibre plus envelope may amount to 0.1 /um for a core diameter of 3 /um. This accuracy is achieved by splitting a light beam, emerging from the end of the fibre which is clamped in an envelope into two beams by means of ro-tating optical means, each of said beams producing a circular image. By a suitable choice and adjustment of the optical means, the two light beams will form opposite-ly moving images when the fibre end is displaced with respect to the axis of rotation and observation. When the images are concentric, the fibre end is situated on the  axis of rotation. Machining of the envelope of a tool which rotates around the axis of rotation results in an envelope which is concentric to the light-conductive core of the fibre.

Abstract: TURBINE CONTROL SYSTEM FOR SLIDING    OR CONSTANT PRESSURE BOILERS            Abstract of the Disclosure An automatic control system enabling comprehensive operation of a reheat steam turbine with sliding or constant pressure boilers.  The control system includes an HP control valve for regulating steam flow to the high-pressure turbine according to load and speed demands, an intercept valve for regulating steam flow to the low-pressure turbine and for reheater pressure control, and a bypass flow system for bypassing excess boiler steam during periods of low loading.  The bypass system includes a high-pressure bypass sub-system and a low-pressure bypass sub-system, each having a flow control valve and provision for desuperheating the steam.  A signal indicative of actual load demand (ALD) and proportional to the product of boiler pressure and main control valve flow demand is produced. From the ALD signal, reference functions are generated to effect control of the bypass valves.  The intercept valve is controlled directly by the ALD signal with a regulation factor inversely pro-portional to the minimum allowable reheat pressure,  Coordinated valve control is effected during all principal phases of turbine operation.

Abstract: D22,215 METHOD AND APPARATUS FOR FORCING A PHASE-LOCK OSCILLATOR            TO A PREDETERMINED FREQUENCY WHEN UNLOCKED by Gerard J. Miille ABSTRACT OF THE DISCLOSURE          An active filter used for the loop filter of a phase-lock loop has one input to the operational amplifier thereof connected to receive the output from a phase detector, and has the non-inverting input connected to receive a control signal from an override signal generator.  Under normal operating conditions, the output from the override signal generator is such that it does not affect operation of the active filter and the filter operates as a standard loop filter.  During abnormal operating conditions the output signal from the over-ride signal generator is of such magnitude that it causes the operational amplifier and, hence, the filter to output the maximum voltage +V.  The filter output is connected to one end of a pair of serially connected resistors which have the node connected to the control voltage input of the voltage control oscillator.  The other end of the serially connected resistors is connected to the collector of a transistor.  The emitter of the transistor is connected to a reference voltage -V and the base is connected through a bias circuit to the output of the override signal generator.  The presence of the override signal causes the transistor to conduct thus, connecting the D-22,215 serially connected resistors between +V and -V.  The value of the serially connected resistors are selected so that the node voltage supplies a predetermined value of control voltage to the control input of the VCO to set the predetermined frequency.
