Filed: 1975-12-23
Abstract: 1490460 Visual indicator for dialled digits STANDARD TELEPHONES & CABLES Ltd 23 Dec 1975 52584/75 Heading H4K To give a visual check of each digit dialled a single digit visual display, preferably an integrated unit LED, shows the content of a counter which counts the impulses in the train of each digit dialled, an interdigital pause detector clearing the counter and extinguishing the display before a next digit can be dialled. In the outline of Fig. 1 impulses are detected and reconstituted by circuits 2, 3, 4, to be counted at 7 with a visual display of the counter contents at 9. A counter 11, driven continuously by an oscillator 10, is reset by the leading edge of each impulse as detected by a differentiator 6. Having been reset by the last impulse of a train the counter 11 measures out an interdigital pause during which the display 9 shows the digit dialled and at the end of which the counter 7 is cleared and the display extinguished. A circuit 12 suppresses the display of a true zero so that the symbol is available to represent the dialled digit "0".

Abstract: 1,025,540. Sealing. L. R. KALB. Dec. 30, 1964, No. 52912/64. Heading B6P. [Also in Division F2] Apparatus for strapping packages comprises a member 3 movable towards a stationary member 5 in order to punch at least two locking tongues in two overlying thicknesses of the strap on either side of a wheel 20 which advances the strap and is in substantially the same vertical plane as the movable member. The wheel 20 has two major diameters (Fig. 2, not shown) externally serrated and spaced apart by a spindle 21 of smaller diameter so as to engage the two edges of the upper straps whilst allowing the punching logs 3a to descend on either side of the spindle when, due to pivoting the lever 10 in the direction P, the punch 3 is pressed down by an eccentric 16 on the lever 10. Prior to punching the strap is tightened by rotating the wheel 20 so as to move the top strap over the lower strap which is anchored by being pressed against the grooved base 23. At the same time as the straps are joined by punching the attached end of one of the straps is severed from its supply by roll by cutting edges at 8, 9. An adjustable stop 18 cooperates with a flat surface at 17 to limit travel of the lever 10. After cutting the punch 3 is raised by the link 13 when the lever 10 is returned to its first position, thereby causing the straps to be raised off the punching member 5 by lifting means 19.

Thermosetting or thermosoling of synthetic fibrous materials is effected by passing heated gas through the material which is spread out over a sieve. The sieve is preferably in the form of a rotating cylindrical sieve 5 which is contained in a closed casing 1 and is under the action of a suction draft, the material being in web form 12. The gas. after being expelled from the cylinder by ventilators 8 passes over heating devices 4 and is recycled to the material. To prevent the sieve perforations leaving marks, the cylinder is covered with a seamless fine meshed sieve with a distance between the wires of less than 1 mm. Several cylindrical sieves may be arranged in series, preferably rotating at different speeds so that overfeeding of the material is achieved to allow for shrinkage. The material may be preheated by passing between heated rolls 11. A water cooled drum may be arranged at the material outlet of the casing 1. An endless perforated band running in a closed casing may replace the cylinder. The web of material may be printed or padded with dyestuff which is fixed in the apparatus. Suitable gases are air, steam, nitrogen and carbon dioxide.
