Abstract: 903,570. Automatic-exchange systems. FUJI TSUSHINKI SEIZO KABUSHIKI KAISHA. May 9, 1961 [May 9, 1960], No. 16899/61. Class 40 (4). A pulse-delaying system comprises two delay lines, each having a series of taps and means for selectively interconnecting any two taps one on each delay line. The invention relates to the selective interconnection of pulse multiplex channels between incoming and outgoing junctions. As shown in a 24-channel system, Fig. 3, a pulse P requiring a delay of 23 units would be routed via gate S(3,20) arranged to be opened at time P+3. The return path for the subscriber uses Fig. 6. Thus the pulse at P+23 enters gate S(-3,-20) at time P+23+4# P+3 and leaves the output terminal at P+3+24-3#P. Gates S(3,20) and S(-3,-20) may therefore be pulsed synchronously. The gates are pulsed from combinations of stores comprising tapped delay lines into which appropriately timed pulses are inserted, Fig. 4 (not shown).

Title: Improvements in and relating to the production of artificial threads by wet spinning
Inventor: GIVENS JOHN HARRISON
IPC: D01D10/04
Filed: 1951-07-18
Abstract: <PICT:0708657/IV (a)/1> An artificial thread obtained by wet-spinning is treated with liquids as it is advancing in helical turns over a pair of rollers; the treatment liquid is supplied to one or more surfaces which touch the thread pack between the rollers so that liquid is taken up by the travelling thread, and the excess of liquid is removed from the thread pack by one or more additional surfaces which also touch the thread pack between the rollers.  The rollers may be arranged one vertically above the other with the liquid-supplying surface or surfaces arranged to touch the thread travelling upwards and the liquid-removing surfaces arranged to touch the thread travelling downwards.  The advancement of the thread in helical turns is preferably effected by disposing the rollers with their axes skewed with respect to one another.  The liquid-supplying surfaces may be provided by glass rods which are slightly inclined to the horizontal so that liquid, e.g. water, applied to one end of a rod will run down the rod until it contacts with the thread pack. The liquid-removing surfaces may similarly be provided by glass rods. Instead of rods, small rotating rollers may be used.  A single rotating roller may be provided between the helices of the thread, the treatment liquid being supplied to one side of the roller.  The apparatus may be used in a process for the continuous production and after-treatment of viscose rayon threads.  As shown, viscose is extruded through a spinning-nozzle 4 and the filaments after coagulation in bath 5 are taken up as a thread 6 which passes to the stepped end 8 of roller 9.  The thread passes a few times around the ends 8 and 10 of rollers 9 and 11, and then round the main parts of the rollers in a large number of advancing helical turns.  The axes of the rollers are skewed so as to effect axial advancement of the thread.  Over the first part of rollers 9, 11 no liquid is applied to the thread but regeneration of the cellulose is allowed to continue. Beyond the regeneration stage the thread is washed with water, supplied by pipe 16 to glass rod 17 which lightly touches the thread as it travels upwards.  Excess of liquid is removed by another glass rod which just touches the thread as it travels downwards.  A drip pan 19 is provided.  The thread passes to a drying device consisting of an internally heated rotating roller 20 and an unheated auxiliary roller 21, and the dried thread is collected on a cap-spinning bobbin. Specification 688,219, is referred to.

Yoke (25a), coil (25b) and poleshoes (29) (Fig. 2, not shown) are located to one side of tube 23 axis, and suppress, leakage fields which may prematurely deflect the beams. Poleshoes (29) are tangential to shell (27) and include an angle of 60 degrees producing a barrel shaped field to effect displacement and additional focusing, and merge into the periphery of shell 27 to facilitate fitting into circular container openings without dismantling. "y" deflecting systems (26) includes ferromagnetic frame (33). Fig. 3 (not shown) includes water-cooled rotatable vaporising crucible (42) with a plurality of cups (43), shaft (45), vacuum container (47), one of two water cooling connections (48), water cooled Cu shield (49), (also Fig. 4, not shown) serving as a sputter quard for the vaporising material and as a collection screen for part of the reflected electrons. Alternatively a crucible may be suspended between poleshoes (29), (Figs. 5, 6, not shown), which are extended by ferromagnetic members (29alpha) forming part of the crucible, further extensions (29b) being connected by magnet (51). Members (29alpha, 29b) and (51) form a supplementary deflecting system. In an alternative arrangement, a rod-shaped material may be continuously fed into an opening in the bottom of a crucible for vaporization at a rate corresponding to consumption.
