Abstract: PHN 9818                                        6.7.1981 ABSTRACT: "A method of writing and reading sector-organized in-formation into and from a record carrier body, and device for performing the method".     A description is given of a method and an associated device for the writing and reading of infor-mation into and from a record carrier body. The record carrier body is preferably made of a radiation-sensitive medium and comprises a servo track. The information is written in consecutively arranged sectors and is read directly after writing for the purpose of verification. A vector address is added to the amount of information to be written in a sector. A vector address of this kind indicates a previously inscribed sector of the record carrier body, said previously inscribed sector having -the property that the information has been correctly written therein. The added vector address enables the transfer of only the correctly written information to a user when the written information is read. The use of so-called "inter-leaving" during the inscribing of information in the record carrier body protects the information written against an error burst.

Abstract: ABSTRACT        This invention relates to apparatus for auto-matically grading and sorting articles, especially fruit, according to size  surface blemish and surface color. Prior art automatic processes have resulted in incomplete grading and are incapable of providing certain important information such as abrupt variations of blemishes and size related information.  The present invention provides an improved apparatus and method for grading and sorting articles, particularly fruit, according to size, surface blemish and surface color.  Fruit is passed sequentially through a camera array which scans the surface of each fruit and measures the intensity of light reflected from successive discrete surface segments.  Significant differ-ences between such measured intensities are detected and a measurement of surface blemish is generated in accor-dance therewith.  Size measurements are derived by count-ing the total number of segments in the surface of each fruit.  Color measurements are derived by averaging the ratio of red light intensity to infrared light intensity reflected from each of a plurality of surface areas of each fruit.  The fruit are separated and delivered to separate receivers by a mechanism responsive to the size, blemish and color measurements of the respective fruit.

Abstract: ABSTRACT OF THE DISCLOSURE A circuit breaker for interrupting current through plural electrical circuits has a separate current responsive circuit path for each electrical circuit.  Each path includes a manually operable latching mechanism capable of engaging and disengaging a pair of electrical contacts on demand and further includes a circuit responsive releaseable latch mechanism for automatically disengaging the pair of contacts.  A common manually activated handle is connected to each of the latching mechanisms to enable manual and automatic operation of the breaker for simultaneous engagement or disengagement of the paired electrical contacts. The connection of the common handle to the several latching mechanisms encompasses a trip bar arranged for both pivotal movement about an axis parallel to the axis of the handle and sliding movement relative to guides within a common insulating case of the circuit breaker.  The disclosed breaker assures tripping of all latching mechanisms, instantly, upon release by any one or more of the circuit responsive mechanisms.  The pivotal and sliding movement of the trip bar eliminates high frictional forces between the linkage portions and permits the use of a minimal overcenter angle to latch the breaker.

Fluorinated ion exchange polymers which have pen-dant side chains containing -OCF2COOR groups and also pendant side chains which contain sulfonyl groups can also be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic group; and also by treatment of a polymer which contains -OCF2CF2SO3H or salts thereof with a combination of fluorine and oxygen.

Abstract: 12                  49,464 ABSTRACT OF THE DISCLOSURE A test system utilizing a plurality of program-mable test instruments each capable of executing portions of a test program with the test program being written in a compiler  language  such as ATLAS,  for  example,  is dis-closed.  Programs specifying the tests to be performed are written in a compiler language such as ATLAS and trans-ferred to a central control processor utilizing standard peripheral equipment.  The central control processor com-municates with a plurality of test instruments utilizing a series of data busses.  In executing the test program, the control processor first segments the program into a series of individual tests to be performed.  The test instruments are interrogated to determine which of the test instru-ments is currently capable of executing a specific se-quence of the test program.  Once an instrument has been identified which  can execute  the program  segment,  the control process transfers that segment to the instrument capable  of executing the  test.  After a test has been executed, the programmable test instrument executing the test transfers the result of the test back to the central control processor for analysis.  In addition to performing the basic test, each of the instruments also has access to the switching matrix so that the required interconnects between the system being tested and the test instruments can be made under the control of the test instrument it-self.  Functionally, each of the test instruments accepts segments of the overall test program in a compiler lan-13                  49,464 guage and performs all the functions necessary to execute that segment of the program and transfer the test results to  the  central processor.  The function of the central processor is to control the system,  allocate portions of the program to each of the test instruments and analyze the  final  test  result.   Alternate  embodiments  provide means permitting any one of the programmable test instru-ments to assume control of the entire system.
