Title: Improvements in or relating to the formation of stitches in material
IPC: D05B1/06
Filed: 1944-05-31
Abstract: 596,146. Sewing-machines; stitches. NEWTON, E. P. (International Button Hole Sewing Machine Co.). May 31, 1944, No. 10481. [Class 112] Loop-stitching; thread-cutters.-A tying stitch is formed at the end of a straight or zig-zag chain-stitch seam, without involving any different movements of the needle and looper or loopers, by means of a loop-deflector which carries the last loop back so that the ends of the two previous loops lie together and interlock with the last loop (one limb of which is subsequently cut and withdrawn). The drawings show the application to a zig-zag chainstitch seam formed by a laterally-vibrating eyed needle and two loopers of which only one, shown at 32<1>, is involved in the formation of the tying stitch. After the last loop l has been inserted by the needle and engaged by the looper 32 and the work has been shifted laterally the position of the loops is as shown in plan in Fig. 10. The stitch-forming devices being stopped in this position, a loop deflector 33, lying close beneath the work-plate, is reciprocated once transversely of the seam; the movement compresses the limbs of the last loop l in the slot 35 of the deflector and carries them across to a considerable distance so that they lie close to the underside of the work, the workplate being cut away at 39, Fig. 9, to allow this. The thread is clamped during this movement, so that thread is drawn from the preceding loops and the thread is also stretched; the last stitches are thus set very tightly so that the last loop is gripped between the two preceding loops, as shown in Fig. 9, and the last stitch is partly embedded in the work as shown at L<z>. As the loop l is carried across by the deflector it is severed by a cutter 40 fixed on the looper 32; the needle-thread can then be drawn out of the work, but the end left remains effectively gripped by the preceding stitches. In a modification the slot 35 of the loopdeflector 33 is omitted. In a further modification, resulting in a somewhat less effective tying stitch, the deflector 57, Fig. 17, is projected from the same side as the looper 55, and is formed with a blunt end engaging the free limb of the last loop and a cutting side which severs the other limb after the stitches have been set as shown. Stopping-gear.-The loop-deflectors are operated by a rock-shaft connected to a sliding member which moves against a spring to take up the shock of stopping. the machine; the mechanism is as described in Specification 594,528. Specifications 25936/02, [Class 112], 476,082 and 596,215 also are referred to.

Abstract: 1,139,602. Telegraphy. ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT. 11 March, 1966 [12 March, 1965], No. 10893/66. Heading H4P. A code converter having 32 inputs corresponding to the 32 combinations of the CCITT alphabet No. 2, i.e. to a "normal" alphabet, comprises means for delivering outputs on only 26 leads, i.e. a "reduced" alphabet. This is done by rearranging the characters in the 32 upper and 32 lower case character positions and by eliminating certain functions such that all necessary functions and characters are contained in 26 upper case and 26 lower case positions. In Fig. 4, each 5-bit character in CCITT No. 2 from tape reader 1 is converted at 2 to a corresponding marking on one of 32 leads. Various of these leads are interconnected by switches, as shown, to feed 26 output leads 5. A relay arrangement 3 controls the various switches in response to signals on certain of the 32 leads. It also controls the tape reader so that, when the reader inputs a character which is represented in the reduced alphabet by a character in a different case, the reader is stopped while a case shift signal and the reduced alphabet character are passed to output 5. The 26 leads 5 may feed a tape punch which records the reduced alphabet message. They may also feed a normal teleprinter which includes a code converter, Fig. 2 (not shown), for returning the data to normal alphabet, switches in the converter being controlled by reduced alphabet case shift signals.

Abstract: 540,507. Aerial photographic cameras. KODAK. Ltd., DAVIES, E. R., SELWYN, E. W. H., and OTAZU, J. M. July 1, 1940, No. 11109. [Classes 97 (i) and 98 (i)] An aerial photographic camera is provided with a plane-parallel glass plate between the objective and the film, the plate being rotatable about an axis perpendicular to that of the objective and to the direction of flight and at an adjustable angular speed so as to compensate the movement of the image on the film otherwise produced by the flight. In cases where the film is continuously moved to produce overlapping exposures, the angular speed of the plate is such that compensation is also made for the movement of the film. As shown, the film is passed from a supply reel 5 through a gate 8 to a take-up reel 13 by sprockets 6, 9, 11 the first and last of which are continuously rotated whilst the sprocket 9 is given an intermittent movement through gears 27, 29, 28 by a multilated gear 26 in order to move the film intermittently through the gate. A sector 30 carried by the gear 26 engages a cut-away disc carried by the gear 28 to lock the gear 28 when it is not being rotated. The take-up spool 13 is rotated through a slipping drive from a gear 25. The sprockets are driven by a motor 14, through a worm drive 18, 19 and gears 20, 21. The motor also drives through gears 41, 40 a rotatably mounted frame carrying the planeparallel glass plate 34, the speed being adjustable so that the image movement due to refraction of the rays passing through it counteracts that due to the movement of the aircraft. The shutter 3 is intermittently operated by a cam 32 also driven by the motor.
