Filed: 1974-02-15
Abstract: 1501623 Rolling; bending INTERNATIONAL HARVESTER CO 13 Feb 1975 [15 Feb 1974] 28927/77 Divided out of 1501622 Headings B3M and B3E A metal workpiece is formed to a desired shape by engaging it between electrodes of refractory metal or alloy, at least one of which serves as a forming tool, and simultaneously resistance heating the workpiece between the electrodes. The process is suitable for forming workpieces of titanium, beryllium, zirconium, columbium or their alloys, nickel alloys, stainless steel or mild steel. The tools may be of molybdenum alloy, or of tungsten, tantalum, columbium, or their alloys. A workpiece bar 50, Fig. 1, is rolled between two refractory rolls 52, 54 which produce localized heating between their nip. Additional rolls 202a, 202b, Fig. 11, upstream of the main rolls, may be provided for preheating the workpiece. Serrated feed rolls 184, 186 force the workpiece between the main rolls, the serrations so formed being eliminated during subsequent forming. In alternative arrangements, Y or H sections are formed between three or four cooperating rolls. A sheet 210, Fig. 12A, may be bent about its longitudinal axis by electrode rollers 92, 94 which force the sheet edges against longitudinal dies 214, 216. The dies are supported by formers 218, 220 backed by rollers 138, 126. The sheet and formers are fed past the rollers in several passes, with the rollers being traversed between successive passes. Different regions of the sheet are successively bent against the die 214 and former 218 and against area 234 of the die 214 (using a different former), Fig. 12B. An insulator in the form of fibreglass tape may be positioned between the rollers and formers, and between the workpiece and former. The workpiece is moved between the support rolls 138, 126 by a ram. During deformation, a conductive lubricant of flake graphite, tungsten powder in a plastic binder, or flake silver may be employed. An inert gas, e.g. argon, can be used to purge the working area to prevent the loss of lubricant by oxidative deterioration. A feedback system can be used to regulate the workpiece temperature or roll force. The heating may be generated by A.C., D.C. or a combination of both.

Abstract: 389,896. Impedance networks ; valve circuits for wireless reception. CARPENTER, R. E. H., 35, Croham Valley Road, Croydon, and ECKERSLEY, P. P., 82, Swan Court, Chelsea, London. Oct. 22, 1931, No. 29404. [Classes 40 (iii) and 40 (v).] A tuned circuit is coupled to an alternating- current source, usually another tuned circuit, to form a band-pass filter, by means of a resistance of approximately the same value as the impedance of the tuned circuit at resonance. As shown in Fig. 1, the source comprises an aerial and earth connected at c, d across a tuned circuit a, b, and coupling to the tuned circuit f, g is effected by a resistance e. This resistance is connected between the highpotential ends of the tuned circuits, or at lower potential points determined by tappings on the coils or by dividing the capacity branches of the circuits, Figs. 9 and 10 (not shown). The resistance e is of the same order as the impedance of the parallel-tuned circuit f, g at resonance, or a suitable fraction of that impedance when a tapping is employed. In an alternative arrangement, Fig. 2, a small resistance q, of the same order as the series impedance of the elements f, g at resonance, is included in both tuned circuits a, b and f, g. Accidental coupling between the coils a, g is reduced by placing them with their axes at right angles on opposite sides of a screen n as shown in Fig. 6, the desired coupling being effected by the resistance e which pierces the screen and has its terminals connected to the respective coils. A sequence of three or more tuned circuits may be coupled by the methods of Fig. 1 or of Fig. 2, or the methods may be employed alternately, with the object of securing constancy of coupling over the tuning range, Figs 3-5, (not shown) ; or both methods may be used jointly for coupling a single pair of tuned circuits, Fig. 8 (not shown). In the radio-receiving circuit shown in Fig. 7, the coupling resistance e between the tuned circuits a, band f, g is variable and is operated jointly with variable leak resistances t1, t2 in the grid circuits of succeeding valves V2, V3. If the resistances are ganged and arranged to increase together, according to a suitable law, the control may be used to vary the selectivity without substantially affecting the overall gain. The tuning-condensers may be gang-controlled, and small parallel trimming condensers may be provided.
Patent GB-365041-A (GB)
Title: Improvements in or relating to textile materials and their production
IPC: D06M15/693
Filed: 1930-10-02
Abstract: Yarns or threads of cellulose acetate or other organic derivatives of cellulose are coated at frequent intervals along their length with a removable size.  When the yarns are woven the size is removed as by scouring, whereby, in the case of high-twist yarns, a crape or cockled effect is produced in the fabric.  The size may be any which is commonly used for the particular material, or may be any of those described in Specifications 348,589, 352,451, and 357,169 which are particularly suitable for yarns which are to be highly twisted, and the swelling treatments described in the above-mentioned Specifications or in Specifications 351,999, 352,000, 356,233, and 357,084 may be applied to the yarns or fabrics to increase the crape effects. The size may be applied to filaments continuously with their production, and may serve to unite the filaments without the necessity of imparting twist or the additional twist usually imparted to slightly twisted filaments; it may also be applied to untwisted or slightly twisted yarns of natural or artificial filaments in bobbin-to-bobbin or other winding or twisting and winding operations, or to yarns of staple fibres of cellulose acetate or other organic derivatives of cellulose.  Highly twisted yarns may be intermittently sized after receiving the whole of their twist or a part thereof; a suitable degree of twist is about sixty turns per inch, and a yarn may be doubled with another, having the same or different twist in the same or in a different direction.  The size may be applied at regular or irregular intervals of regular or irregular duration by means of apparatus such as described in Specifications 325,823, 332,263, 332,290, and 337,433, [all in Class 140, Waterproof &c. fabrics], or by means of a fluted or corrugated roller over which the yarn passes or against which it is pressed by a plain roller, whereby size is applied in correspondence with the corrugations, this means being suitable for treating a number of yarns in sheet form in bobbin-to-bobbin or similar winding.  The yarns are dried relatively quickly by passing around or over heated drums or plates or through a heated atmosphere.  Twisting may be effected simultaneously with winding, but high twisting is preferably effected as a separate operation.  After weaving, the fabric is scoured to remove the size, and, in the case of high-twist yarns, the scouring bath may contain agents to cause the size or the filaments or fibres to swell, such as any of the swelling agents referred to in Specification 352,000.  The fabrics are preferably dried without tension.  The high-twist yarns may be used wholly or partly as weft, and as part of the warp, but, generally, the warp consists of low twist yarns and the weft of right-hand and p  left-hand twist yarn incorporated in any convenient manner, for example pairs of each hand alternating with each other.
