Title: Improvements in or relating to the manufacture of stockings in a single working process
IPC: D04B11/00
Filed: 1950-11-16
Abstract: 684,526. Knitting. SVIT, NARODNI PODNIK. Nov. 16, 1950. [Nov. 29, 1949] No. 28007/50. Classes 74 (i) and 74 (ii). In making a stocking in a single working process on a straight-bar machine, where the heel pocket has been knitted the portion of the fabric preceding the instep and which is supported on the needle shanks of a rockable' middle section of the needle bar, is lifted by an automatically operated device in the direction of the needle axes to a position in which the loops of the last knitted course are beneath the needle beards. At the beginning of the heel pockets, the middle section 2 of the needle bar is rocked to position II, Fig. 3, the movement being such that the needles are not pressed and small enough to avoid breaking of the loops between the extreme needles of section 2 and the fixed sections 1. When a definite length of heel pockets has been knitted the section 2 is worked further, to position III, Fig. 4, in which the needles are out of range of the sinkers. When knitting of the heelpockets is ended, a fabric lifter 9 lifts the loops of the section 2 up the needle stems to a position beneath the beards, where they are retained. The lifter 9 now descends to its idle position (Fig. 4) and the section 2 is returned, first to an intermediate position IV, Fig. 7, for the period of sinker operation and then, as the needle bar is descending and the sinkers are withdrawing, to the initial position in line with the fixed sections 1. The rocking of the section 2 and the operation of the lifter 9 are effected respectively by a cam element 6 having high and low faces and by cam element 19, both mounted on a bar 7 moved laterally, as required, by a rod 21, through a coupling 24, 25. The rod 21 bears a roller 29 running in a cam groove in a drum 31. The drum 31 is rocked round, as required, by pawl and ratchet 39, 38 and is locked in position, between railings, by engagement of a locking pawl 36 in notches in a wheel 34. The drum 31 is rocked whenever the nose of a lever 58 rides off a cam piece 56 or 57 on to the surface of a pattern drum 54, rocking a cam face 64 away from the end of a spring- urged pin 67 so that when a nose 70 of a lever 71 is temporarily moved out of a groove 69 in the pin by the higher point of a cam 45, this pin 67 may be retracted by its spring, from the path of the lever 71 to free the rocking linkwork which is connected thereto, and allow the cam 45 to rock the drum 31. When the nose of lever 58 again rides on to a cam piece 56 or 57, at the moment when lever 71 is again under the influence of the highest point of cam 45; the cam face 64 again projects pin 67 to lock the lever 71 and disable the rocking mechanism.

Abstract: 1,136,710. Digital phase measurement. XEROX CORP. 19 June, 1967 [24 June, 1966], No. 28164/67. Heading G4H. [Also in Division G3] A phase comparator, e.g. for use in facsimile transmission apparatus, comprises an arrange-, ment by which an AND gate 30 or 42, according to whether one set of pulse signals are leading or lagging the other, is enabled to pass clock pulses for a time equal to the phase difference between the signal pulses to a reversible counter which is followed by a digital to analogue converter. The arrangement comprises AND gates 20, 28 and flip-flops 26, 24 which are normally in the reset condition and produce an output at 1. Thus, whichever signal pulse is received first at input 22 or 34 is passed by the appropriate AND gate to set the corresponding flip-flop, which then produces an output on its O terminal and so enables its associated AND gate 30 or 42 to pass the clock pulses. When the other signal pulse arrives on the opposite input terminal it resets the flip-flop and hence blocks the AND gate 30 or 42 and the clock pulses. In Fig. 1 (not shown) the signal pulses are produced photoelectrically from bench marks on parts driven by master and slave electric motors, the slave motor being driven by a multivibrator whose frequency is controlled by the output of the digital to analogue converter.

Abstract: 1395770 Polyamide films TEIJIN Ltd 15 June 1972 [15 June 1971] 28182/72 Heading B5B [Also in Division C3] Shaped articles are formed from polyamides containing 1,4-dihydroterephthalic acid units and during and/or after shaping are heated at at least 100 C. but below the decomposition temperature thereby raising the softening point of the polymer. It is suggested that this may be due to dehydrogenation of the units to terephthalamide units and/or cross-linking. There are preferably at least 5 mol per cent of such units, more preferably at least 30% unless the other acid units are terephthalic or adipic. Numerous possible comonomers are specified. When heated about its softening point the article should be left in a mould but the heating can be effected at progressively increasing temperatures always lower than the gradually increasing softening point. In Ex. 1, hexamethylene dihydroterephthalamide (softening point 155 C.), is injection moulded at 190 C. and the resulting article heated in a mould at 260 C. for 20 minutes. The softening point is then 241 C., increasing after 4 hours further heating at 200 C. to 274 C. Example 3, illustrates a rolled film.
