IPC: H03D7/08
Filed: 1949-11-29
Abstract: 660,546. Superheterodyne circuits. PHILIPS ELECTRICAL, Ltd. Nov. 29, 1949 [Dec. 2, 1948], No. 30591. Class 40 (v). In a frequency-changing circuit more particularly intended for short waves, the signal and local oscillations are both applied to the input circuit of a mixing valve 6 over a band-pass filter 4, 5 which is also coupled to the output circuit of the valve 6 by means of a reaction coil 7 so as to generate the local oscillations. The filter 4, 5 is over-coupled so that its frequency characteristic exhibits two peaks, one corresponding to the signal frequency and the other determining the oscillation frequency. Mixed inductive and capacitative coupling may be used between the two tuned circuits in order to keep the peak separation constant as the arrangement is tuned over a band.

Title: Method for the preparation of pigmented polyesters and articles manufactured from these polyesters
IPC: C08K5/06
Filed: 1958-09-26
Abstract: In the manufacture of pigmented polyalkylene terephthalates, suitable for the manufacture of threads or fibres, by adding a pigment dispersion either to a mixture of terephthalic acid (or an ester-forming derivative thereof) and a glycol of formula HO(CH2)nOH, where n=2-10 or to a low molecular weight polyester formed from these reactants, the pigmentation is effected in the presence of a substance of formula R1-X-R2, where R1 is a hydrophobic group whose hydrophobic property corresponds at least to that of the group CH3(CH2)6-, R2 is a hydrophilic group containing a polyglycolether group of formula -(CH2CH2O)m, where m is 3-49, and X being a group chemically coupling the parts R1 and R2 by primary valencies.  In this substance the group R1 may be an alkyl, aryl or aralkyl group and the group X may be an ether or ester group.  The substance may either be added to the polyester-forming reactants before or during the ester-interchange or polycondensation or may be added to the pigment dispersion.  The pigment may be carbon black, titanium dioxide, barium sulphate, aluminium oxide or a mixture of carbon black and copper phthalocyanine and it may be dispersed in water or in a glycol of formula HO(CH2)nOH, where n=2-10. In examples: (1) ester-interchange was effected between dimethyl terephthalate and ethylene glycol in the presence of zinc acetate, antimony trioxide and p-octylphenylheptaethylene glycol ether, then a dispersion of carbon black in ethylene glycol containing sodium dibutylnaphthalene sulphonate was added, and then polycondensation was effected; (2) ester-interchange was effected between dimethyl terephthalate and ethylene glycol in the presence of zinc acetate and antimony oxide, then a dispersion of carbon black and copper phthalocyanine in ethylene glycol containing sodium stearyl-p-anisidine sulphonate and heptadecyl decaethylene glycol ether was added, and then polycondensation was effected; (3) dimethyl terephthalate and ethylene glycol were mixed with a dispersion of carbon black and copper phthalocyanine in ethylene glycol containing zinc acetate, antimony oxide and octylnaphthyl tetradecaethylene glycol ether, and then esterinterchange and polycondensation were effected; (4) ester-interchange was effected between dimethyl terephthalate and ethylene glycol in the presence of zinc acetate and antimony oxide, then a dispersion of titanium dioxide in ethylene glycol containing eicosaethylene glycol stearate was added, and then polycondensation was effected.

Title: Improvements relating to electrical supply equipment
IPC: H02M7/54
Filed: 1958-07-09
Abstract: 899,631. Converting. SMITHIES, J. July 9, 1958, No. 30934/56. Class 38 (2). In an arrangement for converting current, polyphase A.C. is fed to the primary windings of two or more transformers and the output is taken from series connected portions of their secondary windings, which portions between fixed and movable taps are so cyclically and continuously varied that the output has the desired characteristics. A two-phase supply is connected to primary windings E 1 , E 2  of transformers TN1, TN2, the output being taken from the series connected winding portions between fixed taps t<SP>1</SP> and movable taps t<SP>2</SP> which move 90 degrees out of phase. When taps  t <SP>2</SP> move with the supply frequency the output is D.C. whose value can be varied by altering the phase relationship between tapping points and the supply voltage. When the taps move at a frequency different from that of the supply the output is A.C. with a frequency equal to the difference. With advancement or retardation of the phase of tapping operation the arrangement operates as a capacitor or inductor. A ring of contacts 13 over which brushes 11, 12 move of different lengths and connected to evenly spaced taps or of equal length and connected to unequally spaced taps results in effective sinusoidal movement of the brushes over the windings. With a three-phase supply a pair of brushes moves over contacts connected to taps on star or mesh connected transformer windings, Fig. 3 (Figs. 5, 6, not shown), and the output voltage may be varied by selecting from rings of contacts connected to differently connected taps (Fig. 4, not shown). Various connections of the arrangements in the supply circuits to motors are described (Figs. 7-9, not shown). Mercury jets may replace the brushes.

Title: Improvement in or relating to knitting mechanism
IPC: D04B9/18
Filed: 1931-11-07
Abstract: 388,127. Circular knitting-machines. STANDARD-TRUMP BROS. MACHINE CO., Beach Street, Wilmington, Delaware, U.S.A.-(Assignees of Houseman, H. E. ; Cragmere Road, Edge Moor, Delaware, U.S.A.) Nov. 7, 1931, No. 30950. Convention date, March 27. [Class 74 (ii).] Uniformity of stitch at the two feeds of a machine for knitting split foot stockings &c. is obtained by tilting the sinkers as required. One sinker-tilting cam 38 carried by a rocker 28 and situated vertically above the stitch cam 22 at the instep feed operates on the butts 48 of sinkers 42 associated with long butt needles. Sinkers 40 associated with short butt needles have butts 44 which are engaged by the usual sinker cams and missed by the cam 38. Both kinds of sinkers can tilt on fulcra on the lower edges 41, 43. Sinker-tilting cams 58, 68, situated vertically above the stitch cams 24, 26 at the sole feed are carried on arms 56, 62 mounted on a shaft 54 and operated by a vertical arm 70, the lower end of which runs on a cam 78. During rotary knitting the needles take yarn from fingers 12 at the instep feed, the sole feed being out of action. Upon reciprocation, the cams 20, 22 are partially withdrawn to miss the short butt needles. The long butt needles are raised by deflector cams and miss the yarn at the sole feed. A few needles with butts of intermediate length knit at both feeds and form sutures. The size of loop is determined in a counterclockwise reciprocation by the cam 20 alone, and .in a clockwise reciprocation by the cam 22 and the sinker-tilting cam 38 acting together. To secure uniform loops in adjacent courses the rocker 28 is adjusted to compensate for the difference in level between the points of the cams 20, 22. The cam 20 is made permanently lower than the cam 22 and, since it receives more wear, further adjustment of the rocker 28 from time to time is necessary. The cams 24, 26 are approximately uniform and relative adjustment is obtained by varying the elevation of the cam 68. The cams 58, 68 are also adjustable relative to the other feed to allow for differences in weights of yarns used &c. The needle cylinder can also be adjusted relative to the cam cylinder.

Abstract: 834,992. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS Inc. Oct. 2, 1958 [March 26, 1958(2)], No. 31541/58. Class 39(1). [Also in Group XXII] A method of making a grid for a thermionic valve comprises forming a sheet metal frame with longitudinal beads projecting from the sides of the frame and spaced from its inner edges, attaching a number of parallel wires to the beads so that they extend across the frame aperture and then slightly rotating the sides of the frame so as to bring the side edges of the aperture into contact with the wires and increase their tension. A frame comprising sides 35 and ends 37 surrounding an aperture 33, mounting tabs 23 and upset longitudinal beads 25 spaced from the aperture is stamped out of sheet metal, for example, nickel clad steel. Parallel grid wires 27 are secured between the beads by inserting them in notches 29 which are then peened over as shown in Fig. 2. Alternatively the wires may be attached by brazing, welding or other known means. The frame is then formed to the finished shape shown in Fig. 3 by pressing between upper and lower die sets. These dies form indentations 41 in the ends 37 of the frame, shape the sides of the frame and also bend the sides so that the edges of the aperture move into contact with and tension the grid wires, Fig. 4. In practice two such frames are assembled together to form a grid, being mounted with their tabs 23 through perforated mica plates. The shape of the frames is varied according to whether they are required to form inner or outer grids.
