Title: A sewing machine for sewing decorative stitches
IPC: D05B19/00
Filed: 1963-12-20
Abstract: 980, 042. Sewing machines. MEFINA S.A. Dec. 20, 1963 [March 4, 1963], No. 50543/63. Heading D1G. A zig-zag sewing machine comprises a pack of rotary cams fixed to a driving shaft, an oscillating follower selectively engageable with the cams, a slide rigid with the follower, a finger abutting the slide and coupled to the needle bar gate for transmitting thereto oscillation of the follower, and camselection means having a member which is movable parallel to the axis of the cam-driving shaft by co-operation with a manually-rotatable cam and is so coupled to the follower that the latter is movable therewith while being free to oscillate. A pack of cams 6, fixed to a rotary driven shaft 7, is selectively engageable with a follower 13 fixed to a plate 27 slidable on parallel shafts 14 and 25 which are rigid with a member 23 formed with a slide 24. Shaft 14 is journalled in a structure 15 which is pivoted on a shaft 30, but which is normally fixed. A bar 29, slidable on parallel shafts 30 and 32, carries a member 34 which is forked to embrace place 27, and also carries a follower pin 36 co-operating with a spiral camgroove 37 formed in the rear face of a manuallyrotatable knob 40. Rotation of the latter thereby serves to move member 29 and plate 27 for engaging follower 13 selectively with the cams 6. Knob 40 is held in its positions of adjustment by a spring- biased pin 45. A finger 57 abutting'slide 24 is carried by a link 52 pivoted at 53 to a gate 54 which is pivoted at 55 and slidably carries the needle bar 4. A spring 70 serves to bias finger 57 against slide 24. A bell crank lever 64, pivoted on shaft 7, carries on one of its arms a handle 66 and on the other arm a pin 61 engaged in an axial slot 60 in finger 57. Swinging of lever 64 thereby serves to shift finger 57 along slide 24 for varying the stitch width. An extension 76 of structure 15 carries a follower pin 75 co-operating with a cam groove 74 formed in the upper surface of a manually-rotatable knurled wheel 71. Rotation of the latter thereby serves to pivot structure 15 for varying the centre line of the stitching. Detachably fixed to the upper end of shaft 7 by the means described in Specification 779,038 is an additional zig zag control cam and a work feed control cam.

Abstract: 1535192 Electron beam magnetic deflecting apparatus LICENTIA PATENT VERWALTUNGS GmbH 12 Dec 1975 [21 Dec 1974] 50952/75 Heading H1D An in-line multiple beam cathode-ray tube has line and field deflection coils with a ring-like core 5 having recesses 6 diametrically opposed and each containing a magnet 9, the magnets producing fields each having a static component and substantially transverse to the plane of the beams and effecting line-direction dynamic convergence. Preferably three beams are present and Fig. 1 (not shown) includes vertical and horizontal deflection coils 3, 4. The magnets may be electromagnets fed with adjustable direct current, and dynamic correction currents as required, or permanent magnets 9 magnetized diametrically and movable parallel to the plane of the beams. In Fig. 2, magnets 9 are adjustably secured to a holder (not shown) which is secured either to the tube neck or to core 5. Magnets 9 may be additionally rotatable about their axes and movable in the direction of the tube axis, and their axes may be slightly inclined to the tube axis 12 to compensate for axial errors of the tube system. The polarities of the magnets are mutually opposed in the vertical direction for symmetrical errors and similarly magnetized for asymmetrical errors. Dimensions are given. Vertical direction dynamic convergence may be effected for example by toroidal coils. The correcting action is greater at the periphery than at the centre (Fig. 3, not shown) and any remaining misconvergence in the centre may be compensated by an additional static convergence device. Raster error caused by the deflection unit may also be corrected.

Abstract: 1373524 Electron beam deflecting apparatus RCA CORPORATION 26 Nov 1971 [7 Dec 1970] 55000/71 Heading H1D A toroidal deflection yoke for a delta gun, e.g. shadow mask colour TV tube comprises vertical and horizontal coil winding portions in each of four quadrants defined by vertical and horizontal axes, wherein for minimizing unsymmetrical convergence of a displayed raster in a direction along at least one of the deflection axes, the conductor distribution of at least the vertical or horizontal coil winding portion in a first quadrant is selected to be asymmetrical relative to the winding distribution of the correponding (i.e. vertical or horizontal) coil winding portion in a second quadrant adjacent the first quadrant, the first and second quadrant lying on the same side of a deflection axis along which said unsymmetrical convergence would appear. Corrections may be for misconvergence caused by asymmetry of gun assembly, interaction of getter structure and field, imbalances due to vertical component of earths field. Fig. 2 (not shown) illustrates asymmetric top to bottom misconvergence for a symmetrical yoke, Fig. 3 (not shown), indicating left to right misconvergence with left shifted blue line (32) created by getter structure and field interaction. Left to right misconvergence for example may be corrected by asymmetry in the two lower quadrants, and optionally a slight asymmetry in the upper two quadrants. Other correction combinations are discussed. The Fig. 4 winding compensates for the Fig. 2 and 3 aberrations with first and second winding layers 41, 42, which may alternatively be interspersed in a single layer. Layer 41 is symmetrical and interconnected with layer 42 as in Fig. 5 (not shown). Quadrants I, IV are asymmetric for correction of the Fig. 2 aberration, in the horizontal conductors, although vertical conductors could be asymmetrically altered, as well or instead. For correction of the Fig. 3 aberration the horizontal conductors in quadrants III and IV (layer 42) are asymmetric. Either or both vertical and horizontal windings may be asymmetric. The horizontal coil windings may be series or parallel connected, the vertical windings being normally series connected. Dynamic corner correction waveform circuitry is not required. Fig. 1 (not shown) includes getter structure (18) mounted adjacent the gun assembly along the envelope surface, terminating in structure (19) ahead of the yoke. Yoke conductors are wound about rings (23), (24) on ferrite core (22). Wide angle tubes are mentioned.
