Title: Process for the manufacture of fibres and filaments of linear polyesters
IPC: D01F1/10
Filed: 1961-09-14
Abstract: Fibres and filaments of a linear polyester, especially polyethylene terephthalate are made by adding 0.01-5% by weight of the polyester, of terephthalic acid, isophthalic acid, dimethyl terephthalate, diglycol terphthalate, dimethyl isophthalate, diglycol isophthalate or a mixture of these substances as a decomposing agent to the polyester, and melt extruding the product to form filaments in known manner, the filaments thus made having a specific viscosity lower than that of the original polyester by 0.2 to 0.5 units. The specific viscosities are measured at 25 DEG  C. in 1% solution in a 60:40 by weight mixture of phenol and tetrachlorethane.  The decomposing agent may be stirred into the molten polycondensate at the end of the polycondensation, and the polycondensate then fed to the spinning head, or the melt can be extruded through a slot die, cooled in air or water, the ribbon obtained cut into granules, the granules dried to less than 0.04% water and then melted and fed to the spinning head.  Alternatively the decomposing agent, preferably in the form of granules or powder, can be mixed with polyester granules, e.g. in an offset tumbling mixer, and the mixture dried to a water content of less than 0.04% and then melted and fed to the spinning head. Alternatively the decomposing agent may be dissolved in a solvent, the solution applied to the polyester chips, the solvent evaporated and the impregnated chips dried and spun.  Specified solvents include methylene chloride, dioxane, ethyl acetate and ethanol.  The chips are then dried to less than 0.04% water, melted and fed to the spinning head.  In examples, polyesters of specific viscosity 0.85 are treated with the specified decomposing agents to yield products of specific viscosities of 0.55-0.6. Filaments spun from the treated melts, when made into yarns, show less tendency to pilling than conventional polyester filaments.

Title: Raster distortion correction apparatus for cathode-ray devices
IPC: H04N3/237
Filed: 1965-08-05
Abstract: 1,122,667. Cathode-ray tube circuits. RADIO CORPORATION OF AMERICA. 5 Aug., 1965 [31 Aug., 1964], No. 33658/65. Heading H4T. A raster distortion correction circuit includes a first impedance, comprising a winding 33, Fig. 1, connected in parallel with the line deflection coils 12, 13, a second impedance, comprising a winding 30, connected in series with the coils 12, 14 together with means including a winding 37 which varies the magnitudes of the two impedances in a differential manner in accordance with a control signal from a source 40. Thus, when the signal from the latter varies the impedances to effect pin cushion or barrel distortion correction the total impedance presented to the line deflection circuit remains constant so that undesired variations in other circuits connected to the line deflection circuit, e.g. the EH.T. supply system of a television receiver, do not occur. The winding 30, comprising part windings 31, 32, the winding 33, comprising part windings 34, 35 and the winding 37 comprising part windings 38, 39 are wound on a ferromagnetic core 36 (Fig. 4, not shown) in which a suitable magnetic bias flux is established by means of battery 41 and adjustable resistor 42. Fig. 13, shows a particular embodiment in which the winding 33 is connected in parallel with the line deflection coils 136, 138 via the portion of the line output transformer 120 between terminals 164, 168, the winding 30 being connected in series with the coils 136, 138 and both windings 30 and 33 connected in parallel with a raster width control inductance 169. In this embodiment the control signal applied to the winding 37 (comprising windings 38 and 39 connected in series) is derived from the vertical deflection sawtooth 179 (connected at Y, Y to the vertical deflection coils 146, 148) via diode 171 resistors 170, 174 and capacitor 176 producing a composite waveform which is integrated by winding 37 to cause a parabolic current flow therein thus effecting the required raster correction in known manner. In a modification of this embodiment the winding 30 connected in series with the coils 136, 138, is also connected in series with the winding 33 (Fig. 14, not shown). Modifications of the arrangements for deriving the control signal from the output of the vertical deflection transformer 162 are described with reference to Figs. 15 and 16 (not shown).

Abstract: 485,397. Bourdon pressure gauges. HARCOURT, B. W., and MANN, A. J. Dec. 8, 1936, No. 33662. [Class 106 (ii)] The radial stem is formed or rigidly connected with a portion of rectangular or non-circular form and the casing is reinforced with a complementary peripheral portion with which the stem portion can engage to avoid straining the mechanism while connecting up the gauge. In one form the case is provided with a rectangular slot through which passes the stem carrying the Bourdon tube and its associated mechanism, the part of the stem lying in the opening being of rectangular form to fit the slot. If the casing is of stamped metal thick strengthening pieces are secured to the casing along the longitudinal edges of the slot. If the casing is cast this portion is made thicker. In the form shown, the aperture a is of circular form to accommodate a collar j on the stem d and a pair of thicker pieces k are formed on or secured to the casing. Fitting closely between them is a rectangular part l, on the underside of a flat plate m. The inner end of the stem d passes through a bore through the parts l, m. Relative movement between stem d and plate m is prevented by a flat formed on the stem engaging a straight edge part o of the plate m projecting into the bore. The stem d and plate m are brazed or otherwise secured together after assembly. In a further modification the thicker parts k are dispensed with and an additional plate above the plate m engages the stem d and is of similar section that is provided with a straight edge to engage a flat on the stem. Specification 400,795 is referred to.
