Title: Method and apparatus for the production of crimped yarns
IPC: D02G1/02
Filed: 1966-07-28
Abstract: 1,134,803. Crimping yarns; regulating thread tension. ZINSER TEXTILMASCHINEN G.m.b.H. 28 July, 1966 [28 July, 1965], No. 33940/66. Headings DID and DIF. In the production of crimped multifilament or staple fibre yarns of synthetic thermoplastic materials, such as polyamides, polyesters, polyacrylonitriles, by a method in which at least two separate yarns are fed under tension to a common twisting zone and, after heatsetting of the false-twist thus produced, are separated at a separating point and withdrawn under tension at equal speeds to be finally spooled, the separated yarns reach run through at least one extension zone in which the tensions of the yarns are so controlled and regulated within their elastic range that, when a relative difference in length of the yarns occurs, the tension of the shorter yarn is is increased and the tension of the longer yarn is simultaneously decreased. In the apparatus of Fig. 1, a thread guide 2 limits lateral oscillation of yarn in the twisting zone 1 and enables smooth separation of yarns 6 and 7. If the tension in these yarns are equal and the yarns between the separating point 3 and the draw-off points 52, 53, at the nips of rollers 22, 23, are of equal length, then guide rollers 12 and 13 are symmetrically disposed about the guide 2 and the yarns run over corresponding portions of conical frustra 8 and 9 of equal diameter so that their speeds over coupling roller 10 are equal. However, if the tension of one yarn increases relative to the other, then parallelogram links 16, 17, are urged to one side or the other so that the yarns run over portions of the frustra 8, 9, of different diameters and the tensions therein are thereby correctively and quickly adjusted whereupon the central position of the guide appliances 50 is restored. In a modified apparatus, Fig. 4, yarn guide appliance 51 has a guiding device 40 transversely displaceable by means of guide rails 20 or 21a and 21b and corresponding rollers 25. The rails are joined to form a rigid frame 19 on which guide and deflecting rollers 12, 13, and 14, 15, are mounted. Rollers 25 are fixed and support frame 19 in its horizontal position so as to be displaceable transversely to the run of twisted yarns. Coupling roller 10 comprises a central bearing in a block 26.

Title: Improvements in or relating to a multiphase electrolytic removeal process and apparatus therefor
IPC: B23H3/00
Filed: 1963-08-28
Abstract: Material is removed electrolytically from workpieces by means of polyphase current by employing a number of tool electrodes equal to the number of phases of the current source or a multiple of this and passing current between the tool electrodes and one or more electrically interconnected workpieces whilst an electrolyte is passed through the workpiece - electrode gaps, the working tips of the electrodes being electrochemically inert and together with workpiece(s) being immersed in the electrolyte.  While several electrically connected workpieces may be acted on simultaneously by locating at least one working tip opposite each workpiece, typically either several separate surfaces of a single workpiece are acted upon simultaneously by locating at least one working tip opposite each such surface or a single surface of a single workpiece <PICT:1055170/C6-C7/1> <PICT:1055170/C6-C7/2> piece is treated by grouping several tool electrode tips together as a unitary structure and insulating them from one another, relative movement being imparted between the workpiece and the electrode tips to remove irregularities in the workpiece surface resulting from the insulating regions between them.  As shown three segmental electrodes 42 of copper separated by insulation 46 are supported from a manifold 26 of PTFE or epoxy resin, fed by an electrolyte pressure hose 62, to form an electrolyte feed bore 50 for the working gap, epoxy resin insulating coatings 52, 54 being applied to the bore 50 and the exterior of the electrode segments. The tips 48 of each electrode segment are of electrolytically inert material such as graphite or titanium coated with platinum or rhodium.  For electrode arrays of large diameter or thin workpieces a multiple of three electrode segments is provided.  The workpiece is rotatably mounted Fig 1 (not shown).  In an alternative arrangement, three rectangular copper electrodes 80 separated by insulation 86 and coated on their outer faces with epoxy resin supported from a block of PTFE or epoxy resin and bearing working tips of graphite extending a little beyond the outer margins of the electrode array are disposed to pass through a recessed bushing 76 of PTFE or epoxy resin provided with a number of electrolyte supply pressure hoses 104 and throttled drain hose 110, and adapted to seat in sealing manner on the workpiece, the high electrolyte pressure giving a polished finish to the cavity sunk in the workpiece, e.g. of stainless steel.

Title: Gyromagnetic resonance method and apparatus
IPC: G01R33/389
Filed: 1961-09-22
Abstract: 985,208. Gyromagnetic resonance apparatus. VARIAN ASSOCIATES. Sept. 22, 1961 [Sept. 22, 1960], No. 34083/61. Addition to 939,258. Heading H3B. A gyromagnetic resonance oscillator comprises a sideband resonance system in which the driving radio-frequency magnetic field or the polarizing magnetic field is modulated at a frequency lower than the driving radio frequency to produce side-band resonance, the arrangement being made self-sustaining by selecting one of the frequencies produced and applying it in its correct sense after amplification and detection to effect the said modulation. The transmitter coil 28, Fig. 4, of a crossed coil system is energized by a signal of frequency or from an R.F. oscillator 27 through an attenuator 29, and the R.F. output (# ; #+# 1 , #+2 #1 ) (where # 1  is the modulating frequency), from coil 32 is, after amplification, mixed with oscillations from oscillator 27 in a mixer 34, a filter 35 being provided to select the modulating frequency. The selected frequency is applied to field modulating coil 38 through an audioamplifier 36 and a circuit 37, including a limiter to prevent saturation, the circuit serving to hold constant the amplitude of the resonance signal. A phase shifting network may be included. A single coil system is described with reference to Fig. 5 (not shown.) In an alternative arrangement, Fig. 7, the R.F. driving field is frequency modulated in a unit 56 by the audio output from the resonance system, the audio output being detected by an amplitude detector 61 and being applied also via a discriminator 69 and coils 67 to compensate for field drift. The F.M. signal is limited in a limiter 58 before application to the sample. In a modification of the arrangement of Fig. 7 described with reference to Fig. 8 (not shown), the driving field is amplitude modulated and frequency variation in the gyromagnetic output is detected by a discriminator to produce the modulating frequency. These two systems are insensitive to changes in R.F. gain or to transmitter/receiver coil unbalance. In a further single coil system, Fig. 9 (not shown), wherein the polarizing field is modulated by the audio output, the audio output is used also to control the magnetizing power supply, a frequency discriminator being included in the control circuit, and the arrangement serving to compensate for drift. A sideband resonance electron-paramagnetic oscillator in which the field through a cavity resonator containing the substance is modulated by the detected audio output from a bridge including the cavity in one arm, and energized by a klystron is described with reference to Fig. 10 (not shown).
