Title: Improvements in or relating to sewing machines for automatically producing stitches forming various patterns
IPC: D05B21/00
Filed: 1958-05-02
Abstract: 833,310. Sewing machines. MEFINA SA. May 2, 1958 [[May 9, 1957], No. 14079/58. Class 112 Needles, shifting laterally; work feeding. In a sewing machine having a control device adapted to act upon a needle bar, or upon a work-feed element, for producing a predetermined pattern of stitches, the control device comprises a digital programme controiler furnishing electrical signals, a series of electromagnets to which the signals are transmitted, a series of mobile abutments controlled by the electromagnets and each abutment being adapted to occupy a withdrawn position and a working position, a slidable control member connected mechanically to the needle bar or feed element, and driving means adapted to displace the control member in one or the other direction, the control member comprising arresting surfaces which co-operate with the abutments and are so arranged that each abutment determines two stopping positions of the control member depending on whether the latter engages an abutment when being displaced in one direction or the other. As shown, the swinging needle barcarrying gate 3 of a zig-zag sewing machine is connected by a link 5 to a slidable control member 6 adapted to be displaced in one direction or the other by electromagnets 8 and 9 respectively. The displacement is limited by rods 10, 11, 12 fast with the plungers of electromagnets 13, 14, 15, energization of which causes the respective rod to penetrate the respective one of a series of holes 16, 17, 18 of different diameters in the control member. Each rod when raised is adapted to stop the control member in two positions, depending on which direction the control member is displaced. The control member may therefore be stopped in eight different positions including the extreme left and right hand positions it can occupy when all the rods are withdrawn. The sequence of energization of the electromagnets is determined by a programme controller which comprises a ring 22 embracing an insulating disc 23 driven rotatably by the sewing machine. Mounted in the disc are five concentric rings of contact rods 24, the lower ends of which are respectively connected, via fixed contacts 26a to 26e, to the respective electromagnets. The lower end of ring 22 is connected, via a fixed contact 21, to a source of current 19, and the upper end engages a disc 25 formed with perforations 28 so arranged that some of the rods 24 are electrically connected to disc 25 while others are insulated therefrom. On rotation of the disc, current will pass to the electromagnets in a sequence determined by the perforations 28, the disc being interchangeable to provide various patterns of stitching.

Title: Improvements in electric starting switches
IPC: H02P1/02
Filed: 1922-05-18
Abstract: 202,408. Schattner, E. May 18, 1922. Controllers, actuating - In motor starters, a travelling member c<2> carrying a contact f butts successively against stationary contact studs b and escapes from stud to stud in a series of quick jerks. The movement is obtained by connecting the member c<2> through a link e and spring g to an operating handle h, and arranging, as by a slotted pivoted bearing d, for a radial wiping movement of the contact f over the face of each stud as the spring g is put under tension. In the circular face-plate construction shown, two similarly operated arms c<2> are moved on opposite sides of the centre and pass over two series of studs, the contacts on one side alternating with those on the other side. For a three-phase starter, the contacts of both series are simultaneous. In a modification, a single arm makes a. butt contact and a separate sliding contact at each step. In other modifications the moving member travels in a straight line and is actuated by a solenoid.

Abstract: 662,262. Making wire mesh tape. SPECHT, H. G. May 26, 1949 [April 9, 1949], No. 14146/49. Class 83 (ii). [Also in Group I] Wire.-A method of making wire mesh tape, particularly for use in a filter screen, consists in forming longitudinallyspaced projections on a plurality of wires, carrying said wires into a guide to position and retain them in tape-forming relation with the projections laterally disposed, and while held in such relation carrying them into a heating unit 22 to cause adherence of the wires to each other. The projections 11 may be formed on both sides of each wire 10 and other wires 13 of uniform cross-section are held between the wires 10 and passed through the heating unit. The wires 10, 13 may be of metal or alloy which will cause the projection to join to the wires 13 upon the application of heat, or either or both of the wires 10, 13 may be coated with an easily fusible material such as solder, zinc, silver or the like. Heat may be applied by gas burners, induction heating or resistance welding. In making a cylindrical filter screen, the tape is wound spirally around a frame and the edges of adjacent turns joined by welding, soldering or the like.

Title: Method and apparatus for detecting data on a photographic recording medium
IPC: G03G21/00
Filed: 1975-04-07
Abstract: 1510532 Detecting if a photographic frame has been used SCOTT PAPER CO 7 April 1975 [8 April 1974] 14210/75 Heading G2A [Also in Division G 1] In a device for determining whether or not a particular frame of a multi-frame micro-fiche has been used in an electro-photographic document copying system a dark border is formed around each frame when it is developed. This border is detectable by a photo-electric detector 26 in conjunction with a source 23. The enclosure of the device has a transparent window 15 on which the document 16 is placed and the underneath of the window frame surround has a dark frame-like mask 27. The mask 27's image will be projected (along with the document image) by a lamp 17, a mirror 14 and lens system 19 on to a predetermined frame of the microfiche 12. Thus, after the corresponding frame of the micro-fiche has been developed the film will have a dark "border" developed on it corresponding to the mask 27. This border is detectable by a further lamp 23 and a detector 26 positioned to receive light reflected off where the dark border is expected to be. Thus when the micro-fiche 12 is inserted into the machine it is possible to determine whether or not a particular frame of the micro-fiche has been developed by means of the detector 26's output, since, if it has been developed a dark frame will be present which will decrease the reflectivity and thus the detector's output. The description refers to using other predetermined "marks" other than a border.

A crop conditioner (not shown) is coupled by a draw-bar 68 to a mowing machine connected to a tractor by lift links 11, 12, the arrangement being such that raising the mower to an inoperative position, Fig. 3, still permits the conditioner to be easily towed. The draw-bar 68 is connected to a bell-crank plate 76, 80 pivoted on a shaft 75 to arms 69, 70 projecting from the mower frame 31, and the plate is pivotally connected by a rigid L-shaped link 81 to a pivoted arm 41 of the mower control linkage. When the mower is lifted by the lifting links, the arms 41, 42 swing down about the pivots 44, 45 and move the link 81 to depress the bell-crank plate and the draw-pin 79 to retain the draw-bar 68 and the power take-off shaft 66 in parallel relationship, thus, as seen in Fig. 1, the shafting 66 may be kept low and close to the draw-bar 68 and in a substantially straight line. The mower blades 26 are reciprocated by a pulley 61 and belt 62.

Abstract: 593,063. Radio direction finding. CAPLIN, F., and BAGLEY, J. H. June 7, 1945; No. 14459. [Class 40 (v)] For sense determination in a spaced loop direction finder, the directional pattern is distorted to produce two different patterns by switching an impedance into each loop alternately. The undistorted polar diagram, Fig. 1a, is modified to form alternate polar diagrams, as shown in Fig. 1c, by the switching of the resistance 5, Fig. 2, into the circuits of one or other of the aerial loops 1, 2. The output of the receiver 8 is applied through a switch 10, operating synchronously with the switch 6, to one or other of the valves 11, 12, and is so smoothed that the valve outputs follow the mean signal amplitudes. This output is applied differentially to the centre zero meter 13 which shows no reading when a balance has been obtained. Sense is obtained by a rotation of the aerial system. At one of the zero readings obtained by the equality of the overlapping beams, these being the required balances, the needle will pass through the zero position in a certain direction while at the other true balance the needle will move in the reverse direction. At the intermediate zero positions, the needle will approach zero from one side and subsequently recede while remaining upon the same side.
