Title: Method of producing a high torque synthetic filament yarn
Inventor: CHIBA Y

Filed: 1971-10-29
Abstract: 1374286 False-twisted yarns TORAY INDUSTRIES Inc 29 Oct 1971 [4 Nov 1970 (2)] 50318/71 Heading D1F A method of false-twisting mono- or multifilament yarn consisting of a thermoplastic synthetic polymer comprises heating the yarn to a temperature at which the yarn is plasticized, and false-twisting the yarn by passing the yarn through a closed path formed around a pin 6 or a pin and a guide roller, the yarn enters into and emerges from the closed path while contacting or coming very close to the periphery of the pin, and at entry and exit regions of the closed path 12, the portion 13 of the yarn entering into the path and the portion 14 of the yarn emerging from the path are entwined with each other in at least one turn under friction while travelling in the same direction, whereby the entering portion of said yarn is twisted while being heat-set in the twisted state and then the emerging portion of said yarn is untwisted to convert it to high torque yarn. The pin 6 may be fixed or rotatable. The closed path may also be formed by means of a fixed pin 6 and a rotatable guide roller 15 spaced from the pin 6 and which may be movable about the pin 6. The angle # at which the portions of the yarn 16, and 17 upstream and downstream of the entwining point, cross may be varied by varying the diameter of the pin 6, the diameter of the roller 15, the spacing of roller 15 from the pin 6, and the angular disposition of the roller 15 relative to the yarn path downstream of the crossing point 7. The pin 6 may be made of ruby, sapphire or alumina ceramic material. The yarn produced is a torque yarn without crimp. The number of false-twists in the yarn is affected by the cross angle #, the diameter of the pin 6, the denier of the yarn and the number of filaments. The number of false twists in turns metre is preferably less than 15480/#D.f where D is the denier of the yarn and f the number of filaments; most preferably the number of false twists is in the range 15480/#D.f x 0.40 to 15480#D.f x 0.95 turns/metre.

Title: Method of operating a computer to produce test case programmes
IPC: G06F11/36
Filed: 1975-12-11
Abstract: 1479122 Generating test case programs for testing computers INTERNATIONAL BUSINESS MACHINES CORP 11 Dec 1975 50745/75 Heading G4A A method of operating a computer to produce test case programs, written in a predetermined computer language, which are suitable for checking the operation of computer programs, comprises entering into the computer information relating to the frequency in which particular types of instructions are to appear in a test case program and the total number of instructions which are to so appear; operating the computer to generate instructions having a frequency of type and a total number conforming with the entered information, to predict the results of the execution of each generated instruction including any resultant changes to the test case program's variables to reject any generated instruction that would cause an unwanted interrupt during execution of the test case program, and to generate error checking code for inclusion in the test case program, the code including instructions for checking the flow of execution and for checking the calculated values of the variables against their predicted values; and storing the generated test case program in a form suitable for further use by a computer. Prediction of changes in a test case program's variables may be by way of creation of a dictionary entry for each variable declared in a generated program and maintaining an updated -value for a variable each time it is used in the generated program. The dictionary may be stack-organized according to data type; if a data item is an array the array and its associated status flags are stored elsewhere than in the dictionary and are addressed via the dictionary entry. As described the computer language is PL/1 and details of the generation of IF and DO instructions thereof are given. Generation of particular types of instructions is on a random basis. For example, in an ASSIGNMENT instruction the l.h.s. or target is obtained by selecting randomly a variable from a dictionary stack, and the r.h.s. by calling a subroutine EXPRESSION GENERATOR which generates a random expression and the predicted value thereof. Expression generation is achieved by way of creation, using recursive routines, of a tree structure of operators and operands, evaluation of the predicted value of the generated expression being achieved by list processing of the tree structure. The error checking code includes instructions which call error routines whenever a failure is detected during the execution of a test case program, and automatically generated comments may be inserted in the test case program to aid the tracing of such failures. Following the generation of a test case program a PRINT routine reorders the program, if necessary, prior to its storage for further use by a computer. The test case programs may be used for checking the operation of a compiler.

Abstract: 1,190,665. Multiplex signalling. BRITISH AIRCRAFT CORP. Ltd. 24 Jan., 1969 [9 Nov.. 1967], No. 51137/67. Heading H4L. In a system for transmitting an instruction signal to a remote receiver, e.g. a guided missile, on a single carrier wave, in which the instruction signal consists of an amplitude R and a phase displacement # from a reference signal, a subcarrier is frequency modulated with the instruction signal and combined with the reference signal, the resulting complex signal frequency modulating the carrier or a further subcarrier. Transmitter.-As shown, a 5 KHz sine wave which carries amplitude variations R and phase variations # frequency modulates a 51 KHz subcarrier and then is mixed with a 5 KHz reference signal. Further command tones may be supplied to the mixer. The resultant waveform frequency modulates a 500 KHz subcarrier and is converted into a square wave and finally pulse modulates a V.H.F. carrier. Receiver.-The received signal is demodulated at 14 and the resulting 500 KHz signal is amplified at 15 and supplied to a frequency discriminator 2. A 51 KHz filter 13 extracts the instruction signal which is demodulated at 7 and passed through a 5 KHz filter 16. The reference signal is selected by a 5 KHz filter 5 and the phase adjusted at 10 and by combination with the instruction signal the appropriate control signals may be derived. The command tones are extracted by filters 12, rectified and supplied to a decoder.
