Abstract: ABSTRACT OF THE INVENTION            An uncorrected composite color television signal, including frequency-modulated luminance and frequency-transposed chrominance components is reproduced from a storage medium and separated by filters into its luminance and chrominance compo-nents.  The chrominance component is coupled to a frequency converter for converting it back to its nominal frequency, i.e., its frequency prior to the frequency transposition.  The frequency and phase of the output provided by the frequency converter is determined by a chrominance subcarrier reference signal provided by a generator.  The uncorrected luminance component is employed to adjust the frequency and phase of the signal provided by the generator so that the provided reference signal is coherent with the uncorrected luminance component.  This causes the frequency converted chrominance component to be stabilized to the reference signal and coherent with the uncorrected luminance component.          Both components are then combined and coupled to a conventional line-to-line time-base corrector for correcting any time-base errors that are present in the combined components.                     -2a-

Abstract: Abstract Of Disclosure An artificial tooth for use in a denture compris-ing a base portion, an occlusal portion, and an intermediate portion sandwiched between and secured to the base portion and occlusal portion, the intermediate portion being resil-ient to permit the occlusal portion yieldably to move rela-tive to the base portion.  The intermediate portion is dis-posed generally at equal vertical distances from the occlu-sal surface of the occlusal portion and the ridge lap sur-face of the base portion.  Anchor wires or other connecting members are provided for limiting the movement of the oc-clusal portion relative to the base portion.  Each anchor wire may preferably be rigidly connected to the occlusal portion and loosely pivotally connected to the base por-tion with the anchor wire extending downwardly through the sandwiched intermediate portion.  The loose pivotal con-nection permits the occlusal portion to move from its normal position toward the base portion even by tipping movement.  Two such anchor wires, spaced apart in the central mesial-distal plane of the tooth, prevent the occlusal portion from twisting relative to the base portion.          The anchor wires prevent the occlusal portion from moving from its normal position away from the base portion.

Abstract: ABSTRACT OF THE DISCLOSURE An archery bow having a riser that is adapted to be grasped by an archer and which has a face and upper and lower, opposite end portions. The inboard ends of a pair of elongate spring members are mounted in cantilevered fashion from the face of the riser, one is in association with each opposite end portion thereof.  The medial portion of a limb member, in the fashion of a second degree lever, is pivotally mounted on the outboard end of each elongate spring member.  A bow string ex-tends between the outboard ends of the two limb members, and a cam follower is presented from the inboard end of each limb member to engage a corresponding cam secured to the face of the riser and which serves as a fulcrum against which the limb member acts to cock the spring member in response to the application of a drawing force to the bow string.  The configuration of the cam determines the functional interrelation of the draw weight in response to the draw displacement of the bow string.  Means are provided to synchronize movement of the limb members, and the spring members as well as the cams are preferably individually adjustable.

Abstract: ABSTRACT OF THE DISCLOSURE           An inspection apparatus for inspecting and detecting flaws in serially fed substantially cylindrical objects. The inspection apparatus includes a notch-shaped inspection station formed by a pair of drive wheels mounted on a first shaft and a pair of discharge wheels fixedly mounted on a second shaft, parallel to the first shaft.  A book having a convex back surface is connected to and protrudes beyond the circumference of each discharge wheel.  An L-shaped bracket whose body includes a sending surface and whose leg includes an infeed cradle, is mounted above the drive wheels and pivots in synchronism with the rotation of the discharge wheels.  A first object in the infeed cradle is positively sent by the bracket sending surface towards the inspection station where it is rotated and inspected for flaws by sensors mounted axially on an imaginary straight line drawn from the axial center line of the inspection station to the axial center of the first or second shaft.  A kinematic drive system keeps objects stable while they rotate in the inspection station by the drive wheels driving the objects into the inspection station, and, with the cooperation of magnets below the station, keeping the object in contact with the discharge wheels.  The kinematic drive system includes a slip clutch assembly which communicates with the drive wheels and connects them to the first shaft.  The slip clutch assembly is adjustable for imparting pre-set desires limited slip torque values to either or both drive wheels to allow either or both to slip in the first shaft, when either or both is subjected to a torque whose value exceeds the pre-set limit.  The kinematic torque drive system, along with the axial alignment of the sensors on the imaginary straight line allow a substantially uniform gap to be maintained between the sensors and the object regardless o f whether objects are out-of-round. When the object is a ferrous can body and its rim portion is to be inspected, a magnet on the side of the inspection station axially aligns the can in the station and orients its rims with the magnetic sensors.  A primary magnet below the inspection station whose axial length is shorter than that of the ferrous can body, induces a magnetic field through the can body portions axially beyond the magnet and the magnetic sensors detect disturbances in the magnetic field caused by flaws in the rim.

Abstract: ABSTRACT OF THE DISCLOSURE      An optical assembly is provided which comprises a light source, preferably a laser, and a particularly compensated prism unit, the la-ser and the prism unit being mounted on a common holder or base.  The beam emitted from the laser is reflected 90° by the prism unit, and although this unit is only approximately aligned with the laser the reflected beam will always form a right angle to the incident beam with an extreme accuracy, the deviation from 90° being less than half an angular minute.  The accuracy in reflexion independently of prism unit setting is attributed to the compensated prism unit, which com-prises a quadrangular prism composed of two semi-quadrangular prisms. a reflecting surface being mounted, preferably in an adjustable posi-tion, adjacent one side of the prism.

Abstract: ABSTRACT OF THE DISCLOSURE            A pressure sensing device is disclosed having the pressure sensing diaphragm positioned in a housing which is not stressed or enlarged by large static pressure.  The housing is attached within a recess of a larger casing by means of a support diaphragm.  The recesses are communicated with the interior of the housing by passages therethrough to equalize the pressure inside and outside the housing.  The outer side of each casing forms a pressure reception chamber with a respective pressure receiving diaphragm.  The latter chambers communicate with the recess via passages in the casing.  The space between the pressure sensitive diaphragm and each pressure receiving diaphragm, including the housing interior chamber, the housing passage, the casing recess, the casing passage and the pressure receptive chamber, is filled with a fluid.  The construction and filling is such that overpressure on one pressure receiving diaphragm causes the entire housing to move toward the inner wall of the casing.  However the latter diaphragm closes with the outer wall of the casing before the housing contacts the casing inner wall.
