Abstract: ABSTRACT OF THE DISCLOSURE:   One or more optical fibers are loosely enclosed in a tubular plastic sheath so as to be slidable with respect to the sheath.  The fibers may be longer than the length of the corresponding surrounding sheath.  The sheathed fibers are wound around a core and covered with a further sheath to form a cable.  In the pro-cess, the optical fiber is treated with an anti-adhesive material before the sheath is extruded thereover and during the subsequent processing the sheath, which has a length greater than the length of the enclosed fiber, either be-cause of its temperature or because of mechanical stretching, is allowed to contract while in non-slidable relation with the fiber, thereby providing a fiber length greater than that of the sheath.

Abstract: ABSTRACT OF THE DISCLOSURE      Video disc player is provided with a sync separator which is responsive to output of luminance comb filter after de-emphasis circuit processing.  Input to comb filter cir-cuitry is provided by amplitude modulator, responsive to carrier wave oscillations from a voltage controlled oscillator (VCO) and to composite video signals provided by a defect compensation system.  The compensation system normally supplies an output directly derived from the player's pickup circuits, but, under defect conditions, substitutes stored video signals.  The VCO is a component of a phase locked loop (PLL) arrangement, also including a burst gate for selectively passing color synchronizing information contained ion the modulator output.  Gating pulses for the burst gate are generated by apparatus responsive to the sync separator output, the generating apparatus including a cappa-citor charging circuit activated by the trailing edge of a separator output pulse to control gating pulse termination, and a separate capacitor discharging circuit activated by the trailing edge of a separator output pulse to control gating pulse initiation.  Also responsive to an output of the sync separator is a keying pulse generator for controlling keyed clamping of the luminance comb filter output, with keying pulse timing determined by differentiated and inte-grated versions of the separator output.

Abstract: WATER DEPTH MEASURING DEVICE            Abstract of the Disclosure A device for use in determining the depth of water accumulating on the surface of a pathway, such as an airport runway or the like.  A block of electrically insulative mate-rial is embedded in a pathway with the top surface of the block being substantially flush with the pathway surface and exposed to atmospheric precipitation.  A sensor comprising first and second capacitors, each of which has first and second coplanar spaced apart electrodes, is positioned within the block with the electrodes of the first capacitor positioned adjacent to and inclined with respect to the top surface of the block and with the electrodes of the second capacitor being positioned a substantially greater distance from the top surface of the block whereby an accumulation of water on the surface of the block af-fects the dielectric, capacitance and conductance of the first capacitor without substantially affecting the dielectric, capaci-tance and conductance of the second.  Time-varying out-of-phase electrical signals are applied to the first electrodes of the capacitors as the input to the sensor.  An output circuit com-monly connected to the second electrodes of the aforesaid capaci-tors supplies an electrical output signal relative to electrical ground from the sensor.  At least one electrical conductor within the block is connected to electrical ground with a portion there-of exposed to the atmosphere at the top surface of the block.  Ac-cumulation of water on the surface of the block affects the ca-pacitance and conductance between the output circuit and elec-trical ground whereby the amplitude of the electrical output signal of the sensor is a function of the depth of water accu-mulating on the surface of the pathway.

Each piece of a set has a particular design in a particular color on one exposed surface of a piece. The other exposed surfaces of each piece are un-marked. The design and color utilized have been selected to be easily recognized by a young child and distinguishable from the other designs and colors used. A fixed number of pieces are selected randomly by players of the game to form a hand leaving a set number of remaining undivided pieces. Each selected piece can be conveniently placed in a support rack carried by a four-sided frame of a playing board. Each player in rotation then selects a piece from the undivided remaining pieces. The player retains the selected piece if the design or color of the design matches that of a piece in the hand. If the design or color of the design does not match, the player discards that piece or another piece such that the number of pieces in the hand remains the same. The first player to obtain sets of matching pieces is a winner.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure relates to a method of binder removal from a green body before sintering or the like wherein the green body is initially heated to a temperature above the flow point of the binder to liquify the binder and, at this elevated temperature, surrounded by a solvent for said binder in the vapor phase and at a temperature slightly above the melting point of the binder.  The solvent vapor enters the green body slowly and dissolves the binder therein so that excessive stresses are not provided within the body due to binder expan-sion until binder-solvent substantially ceases to exude from the body.  The body is then placed in a bath of the solvent, the solvent being maintained at a temperature above the flow point of the binder to remove remaining binder from the body.

Abstract: ABSTRACT OF THE DISCLOSURE:             A roll of the type which is used in paper machines has an inner roll body provided with an outer covering made up of a series of elongated strip portions which circumfer-entially surround the inner roll body while being distributed axially therealong and engaging each other.  These strip portions are welded to each other and also may be welded to the inner roll body.  The welding of the strip portions is carried out by way of an electron beam type of welding which can be oriented so as to achieve one or more of a number of different types of weld connections between the successive strip portions and, if desired between the strip portions and the inner roll body.  Where the strip portions form part of an elongated strip which is helically wound onto the inner roll body, the welding by way of the electron beam can take place simmultaneously with the winding of the strip onto the roll body, and by suitable controls the welding can be con-tinuous welding or the welding may be applied at predetermined intervals to provide a discontinuous type of welding.
