Title: Textured textile yarn
IPC: D02G1/00
Filed: 1968-11-06
Abstract: 1,247,023. Texturing yarns, knitted fabrics. J. P. STEVENS & CO. Inc. 6 Nov., 1968 [13 Dec., 1967], No. 52539/68. Headings D1F and D1K.  A monofilament, thermoplastic, e.g. nylon, yarn is textured by flattening selected portions (20-62 per linear inch) of the heat softened, previously drawn yarn so as to form segments of altered cross-sectional shape in the yarn in a uniform pattern whereby the yarn exhibits a variation in bending modules along the length thereof. The pressure and temperature of such treatment are so controlled as to effect permanent distortion of the yarn while maintaining a residual shrinkage of at least 5% in the flattened yarn. The latter is cooled whilst maintained in tensionless condition and the textured yarn is wound into a package under a controlled tension which prevents any further drawing thereof. As shown, a sheet 13 of monofilaments passes from a beam 11, through a reed 15, between one or more pairs of rolls, as at 19, 21, one roll driven and having a grooved surface to effect flattening of the monofilaments at intervals and the other roll smooth-surfaced, one or both rolls being heated internally as by circulating oil. Take-up rolls 25, 27 may effect positive filament cooling prior to package formation. In a knitted fabric comprising textured yarns combined with untextured yarns, effects, e.g. crepe, may be caused by a loop distortion produced during the knitting cycle due to the varying bending modules.

Title: A combined buff and draw gear for central buffer couplings on railway vehicles
IPC: B61G9/08
Filed: 1969-11-03
Abstract: 1,273,440. Combined buff and draw gear. RHEINMETALL G.m.b.H. 3 Nov., 1969 [15 Nov., 1968], No. 53687/69. Heading B7T. Combined buff and draw gear for a railway vehicle centre buffer coupling comprises a housing 4 having slidably mounted in one end a member 7 connected to the coupling and projecting inwardly therefrom an hydraulic damper cylinder 8 which co-operates with a piston connected with a cap 5 at the opposite end of the housing, there being coaxial with the damper three columns I, II, III of friction springs, wherein during buff all the columns are effective together with the damper, but during draw only columns I and II are effective. During buff, pressure from the coupling is transmitted successively through a web 9 of slide member 7, a slide ring 22, column I, ring 23, column II, ring 18, bush 16, intermediate tube 12, ring 15, column III to body 19 with a stop ring 21. Also some of the force is absorbed by the damper with fluid from space 8a flowing through passages 25 past valve 26 and through passage 27. The column III will be fully compressed first when the end of flange 17 abuts stop flange 24, the column II will become fully compressed, second when ring 23 abuts the end of bush 16, with the column I fully compressed last. On the return stroke fluid passes from space 10a to space 8a through valve 28. Upon draw loading, the damper is hardly effective since fluid passes only through return valve 28 with the force being transmisted successively through web 9, tube 14, tube 12, bush 16, ring 18, column II and ring 23 and column I to ring 22 abutting portion 6 of the housing comprising an end stop. The column III is not utilized and column II becomes fully compressed before column I. A fluid reservoir 31 is connected to space 10a.

Abstract: 1,103,799. Determining angular displacement of a rotating shaft. GENERAL ELECTRIC CO. Dec.20, 1965 [Dec. 28, 1964], No.53790/65. Heading G1A. In an arrangement for sensing optically the relative angular displacement between the axis x of a rotating member and a reference axis y, a reflecting surface making an angle with a plane normal to the x axis is mounted on one end of the member, a collimated beam e, f of light is directed parallel to the reference axis on to the reflecting surface so that the reflected beam sweeps out a conical surface, and an adjustable iris shutter 28 is provided for masking the outer portion of the annular path of the beam together with a photo-sensitive member 34 responsive to changes in masking arising from the angular displacement. The arrangement is applied to a cryogenic gyroscope 10 in a gymbal mounted housing 12 the axis of which is maintained in alignment with the axis of the gyroscope by torquers controlled by the sensed displacement signal. The light from a lamp 16 is focused by a lens 18 on a pinhole reticule 20 and provides the beam e, f, through a two-prism beam splitter 22 and a lens 26. The iris is disposed in a plane spaced from lens 26 the same optical distance as the pinhole, and the partly masked beam Q rotating around the edge of the iris is rendered stationary on photo-sensitive tube 34 by lens 32. A pulsatance developed by misalignment is demodulated in 36 by mixing with the output of an oscillator 44 the frequency of which is locked by a second beam from the beam splitter which rotates around the periphery of a lens 40 and falls on a photo-cell 42, the lens having a radial line 46 which interrupts the light each revolution.

Abstract: 1,245,147. Programme control of machine tools. GENERAL ELECTRIC CO. Nov. 15, 1968 [Nov. 15, 1967], No.54446/68. Heading G3N. A system for controlling a machine moving member stores blocks of offset digital data of a plurality of separate pattern programme digital data relating to positions about an offset point and successively reads the offset data blocks and carries out a selected pattern programme through a machine director. As shown, a tape reader 1 reads position information from a tape 2 and a tape reader 3 reads information, concerning a pattern of operations to be carried out at the position, from a tape 4. The information is presented in alphanumeric form and the tapes are magnetic or paper. The position reader 1 first reads information stored on tape 2 into a decode AND-logic circuit 6 which responds to offset commands U, V by closing switches 7a, 7b to feed position values to an offset register 5 through a decoder and distributor 9. The recognition of a command Q, determining the pattern of holes to be punched at the offset position, causes a switch 12 to close and the pattern code Q, through a contact 13a, to be fed to a pattern search command store 15 from the decoder and distributor 9. The code Q is also fed to a reader control 17 to enable a subsequent search of the tape 4 to be effected on receipt of an end-of-block command M, read by logic 6, which closes a switch 18 to initiate, through the reader control 17, operation of the reader 3 and search of the tape 4 for the pattern stored in command store 15. The codes Q are read and, through switch 12 and a contact 13b, fed to a pattern number store 24 the contents of which are compared by a comparator 25 with the stored pattern in store 15. On equality being attained, the comparator, through reader control 17, initiates the read-out X, Y values which, through circuit 9 and, by logic 8 controlling switches 7c, 7d, are fed to a command register 28. A punch tool selecting code T is then read and fed by logic 6 controlling a switch 29 to the command register 28. The command register derives U+X and V+Y values which, together with the tool code T is fed to a machine director 30 which effects a working operation by a tool 32. On completion of the operation a signal is sent to the reader control which initiates the next step in the selected pattern of operations. The pattern is completed on receipt of command M, from tape 4, which, through reader control 17 initiates the operation of reader 1 to read out the next offset from the position tape 2. The programme is completed on receipt of a command M from tape 2. The reader 3 is commanded to search in a reverse direction by the reading of a negative sign associated with the command Q from the tape 2.
