Abstract: APPARATUS AND METHOD WHEREBY ENERGY IS CORRELATED WITH GEOMETRY OF A MANUFACTURED PART OR THE LIKE OR TO POSITIONAL                 RELATIONSHIPS IN A SYSTEM            Abstract of the Disclosure A way of automatically inspecting a machined part, for example, to a tolerance of 0.001 inches.  A minicomputer monitors a change in phase, for example, of wave energy impinging upon a sample part and compares it with a change in phase of such energy for a standard or master part, any difference between the monitored changes being interpreted to determine if the sample is within acceptable tolerance limits.  The inspection approach described uses no moving parts and can be used to inspect many dimensions of a part simul-taneously in less than a second.  Acoustic waves or microwave electromagentic wave energy can be used to inspect parts of any shape.  The inspection system disclosed can be used, as well, to monitor the geometry of an object over time to note any changes in said geometry.  And the concepts of the inspection system can be employed in conjunction with robot-controlled devices to provide close-positioning data for such devices.

Abstract: ABSTRACT OF THE DISCLOSURE        A method for determining parallax effects in a stereoscopic optical system, such as a binocular range finder, is disclosed.           Also disclosed is a stereoscopic optical system. An optical grating structure is disposed in the path of imaging flux of optical imaging means of the system and two electrical signals are derived by photo-electric detectors from mutually distinguishable optical fluxes received from the grating structure. The two electrical signals are subtracted from one another and one of the two electrical signals is differemtiated. The difference and differential signals are multiplied together and a control signal is derived from the prodyct signal.           The control signal is indicative of the parallax effects and is utilized to control indicator means and/or control serve means for adjusting optical elements in the system to compensate for parallax effects.

Abstract: DATA ACCESS CIRCUIT FOR A MEMORY ARRAY     Abstract of the Disclosure A memory array, having a plurality of intersecting rows and columns, stores digitized speech.  Each row and column intersection consists of a binary storage cell for storing one bit of digitized speech.  Incoming digitized speech is loaded into columns of the memory array in a plurality of repetitive loading sequences, each loading sequence including; reading out the bits stored in success-ive rows of binary storage cells, replacing in each successive row of bits, a predetermined one of the bits in the read out row with a successive one of the bits of the digitized speech and writing each read out row of bits including the replaced bit back into the row.  Multi-bit binary grunts (digitized speech segments) stored in the array are read out therefrom by applying the bits of the grunts to time slots in frames on a time-division highway, each frame being of n bits duration and including one bit from each of n grunts stored in the array.  A selected grunt is extracted from the highway by commencing a count of the bits on the highway with a first bit of the selected grunt and by extracting the first bit and every nth bit thereafter.  Memory malfunction is indicated when the number of rows in the array containing parity errors exceeds a predetermined threshold number.

Abstract: Title of the Invention Flyback transformer with high tension connector Abstract of the Disclosure A low tension and a high tension coil on a flyback transformer are coupled together with an output rectifier connected with the high tension coil by an enclosure of an electrically insulating material.          A hollow cylindrical connector body of an electrically insulating material is attached to the enclosure, and has one end of a greater inner diameter than that of the other end, with a step formed intermediate the both ends. Said one end of the connector body is disposed within the enclosure and is adapted to receive a conductive cap electrically connected with the rectifier while said other end opens outside the enclosure. The flyback transformer is mounted on a television receiver, and the end of a high tension lead wire is inserted into the connector body of the flyback transformer through said other end in order to supply the rectifier output to a cathode ray tube. At its inner end, the high tension lead wire is rigidly formed with a fastener of an electrically conductive material and having a plurality of resilient wings, which engage the conductive cap and are locked by the step when the inner end is inserted into the connector body.

Abstract: COMBINED MUTUAL DRAINAGE REACTOR AND GROUNDING RELAY       ABSTRACT OF THE DISCLOSURE            A combination mutual drainage reactor and grounding relay for protection of a two-wire communication circuit comprising a pair of inductively coupled coils each having one end grounded and the other end connected to a corres-ponding communication line through one of a pair of magnetically operated, normally open S.P.S.T. gas-filled reed switches which are disposed in the common magnetic circuit of the two coils and which have predetermined voltage breakdown characteristics between their open contacts.          A voltage from one line to ground in excess of the breakdown voltage characteristic of the connected reed switch causes current flow across the open switch contacts and through one coil to ground.  The voltage thus impressed across this coil produces an equal voltage across the other magnetically coupled coil, which, in turn, causes the other reed switch to conduct, thereby preventing abnormal line-to-line voltage and maintaining balanced line-to-ground voltages.  When the overvoltage ceases, the reed switches become non-conductive and isolate the drainage  reactor from the communication lines.          If the line overvoltage and the proportional currents flowing between the open contacts of the switches exceeds a predetermined value and/or persists for a pre-determined time, the magnetic force on the reed switches will close these switches while such current persists to protect the reed switches from open contact operation in excess of their rated capacity for such operation and to minimize erosion of the switch contacts while conducting current across open contacts.
