Title: Improvements in or relating to crimped yarn
Inventor: FAIRLEY KENNETH DUFF
IPC: D02J1/22
Filed: 1960-04-01
Abstract: <PICT:0911509/IV(a)/1> In a crimping process (see Group IX) undrawn or incompletely drawn synthetic linear polymer yarn of continuous filaments is drawn in the solid state at a neck.  The temperature of the yarn at the neck is controlled so that there is at this point a unidirectional temperature gradient through the filaments of the yarn along a line perpendicular to their longitudinal axes.  The yarn is relaxed, under wet or dry heat-treatment, to an extent which may be controlled.  The polymer may be a polyamide, polyester, polyolefine including polypropylene, polyurea or polyurethane.  As shown, undrawn yarn passes from a supply bobbin 1, through a pretensioner 2, over a drying heater 3, around a feed roll 4 and separator 5, over a wick 7 supplying liquid 6, e.g. water, carbon tetrachloride or paraffin oil, for improving thermal contact between the yarn and any heating surface, and around a water-cooled snubbing pin 8.  In the vicinity of the point where the yarn leaving the pin 8 is elongated at the neck, the yarn passes through the heat rays emanating from an incandescent coil 9 or a hot, flat, ceramic plate or jet of hot air (not shown), then proceeds to a draw roll 10 and separator 11 and, on leaving the draw roll, relaxes or is allowed to relax by means of another roll (not shown) which may be heated and runs at a lower peripheral speed than the draw roll.  Specification 785,978 is referred to.

Title: Improvements in or relating to organic isocyanates
Filed: 1951-05-18
Abstract: Organic isocyanates RNCO in which R is an organic radicle, preferably a hydrocarbon radicle, are made by dehydrohalogenating, in the presence of an organic dehydrohalogenating base which is free of primary and secondary amino groups, a substituted N-haloformamide HCON (X) (R) in which X is Cl or Br. Representative of groups specified for R are methyl, tert. amyl, octadecyl, cyclopentyl, phenyl anthracyl, phenethyl, p - butylphenyl, nitrophenyl and chlorophenyl or it may contain a second N - haloformamido group as in 1, 8-di-(N - chloroformamido) - p - menthane.  Pyridine, triethylamine, benzyldimethylamine and dimethylaniline are specified bases.  The base is used in amounts equivalent to or in slight excess of the stoirchiometrical amount of the formamide.  The reaction is preferably effected at about 20-100 DEG C.  Superatmospheric or reduced pressure may be used and inert solvents employed.  In Examples (1) N-methyl-N-chloroformamide with quinoline yields methyl isocyanate, (2) N - butyl - N - chloroformamide with pyridine yields butyl isocyanate, (3) N - tert.-butyl - N - chloroformamide with quinoline yields tert. butyl isocyanate, (4) N - tert. octyl-N-chloroformamide with pyridine yields tert. octyl isocyanate (stated to be a new compound) and dodecyl isocyanate is similarly made from N - dodecyl - N - chloroformamide and in (5) N - butyl - N - chloroformamide with benzene and triethylamine yields butyl isocyanate.  The N - halo - formamides are stated to be novel compounds and are made by treating the corresponding formamide HCONHR with a hypohalite, preferably with a tertiary-alkyl hypohalite.  The formamides may be made by reacting an olefine with hydrogen cyanide, water and sulphuric acid, e.g. 1,8 - di - (N-formamido)-p - menthane is made by reacting dipentene or a -terpinol with these reagents.

[Class 28 (ii)] In narrow-guide mechanism for a slicing-machine, the guiding means are arranged below the feedtable 11 and comprise a stationary guide part 16 on the under table or carriage 12, and moving guide parts 14, 15 cooperating therewith, the part 15 being a releasable braking member. The table 11 is detachably secured to the side block 13 which is integral with the part 14, and the part 15 is movable longitudinally and away from the part 16, this movement being permitted by a pin-and-slot mounting 22, 23 on the block 13. The part 15 is normally pressed towards the part 16 by inclined plungers 20 pressed towards the part 15 by springs. The plungers have wedge-shaped ends which engage in under-cut ends 24 of recesses 21 in the part 15. Means, described below, are provided for moving the part 15 longitudinally, against the action of the plungers 20 which are thus forced backwards and away from the part 16. During the backward movement, the wedge-shaped ends of the plungers, being engaged in the undercuts 24, pull the part 15 away from the part 16. The longitudinal movement of the part 15 is effected by a handle 29 pivoted at 30 and having a double-humped cam which engages a lever 34 pivoted at 35 and swings it clockwise irrespective of the direction of movement of the handle 29. The lever 34 bears against the pin 22 on the part 15 which is thus moved against the plungers 20. The handle 29 has also a cam formation 31 which engages a roller 32 on the feed nut bracket 27, the cams raising the feed nut when the handle 29 is pulled in either direction to relieve the braking-action and to move the feed table. If it is desired to advance the feed table by hand, the handle 29 is moved still further to engage the roller in a part of the cam which holds the feed nut disengaged. A spring 36 tends to keep the feed nut in engagement. Dirt is excluded from the guide parts by a plate 18 secured by screws 19 to the stationary guide part 16. The feed screw 25 is housed in a stationary slotted tube 26 which is embraced by a part 13a of the slide block 13.

Abstract: 310,329. Westinghouse Lamp Co., (Assignees of Slack, C. M.). April 23, 1928, [Convention date]. Vacuum tubes.-The window of a cathode-ray or like tube for the passage of electrons or ions consists of vitreous material of not more than a few thousandths of an inch in thickness. The material for the window may be glass, such as lime glass, boro-silicate glass or glass known by the registered Trade Mark, " Pyrex," quartz or non-porous porcelain. The thickness of the window is about 0.00025 inch, or in the case of a small window 0.0001 inch; details of the absorption of energy at different voltages are given. As shown, the window 14 is formed by drawing in a part of the envelope to form a bulbous part. The window may be formed on the closed end of a short length of tube which is subsequently sealed to the envelope. The thickness of the window increases gradually from the centre outwards, and the thickness may be further reduced by etching with a weak solution of hydrofluoric acid. The thickness of the window may be determined by the voltage required to cause cathode rays to pass through. The surface of the window inside the envelope may be coated with a thin film of conducting material connected with the anode 3 so as to prevent the accumulation of a negative charge on the window. The outer surface of the bulbous part below the window is coated with a strengthening and shielding material such as shellac to prevent heating of the glass by impact of stray electrons. The cathode 2 consists of a coil of tungsten or molybdenum mounted within a focusing cup 8 and surrounded bv an electrostatic shield 9 in the form of a split tube of nickel, monel metal, or chrome-iron. The anode consists of a copper tube having a flared end 15 and supported by a split collar 13 of chrome-iron or other metal.
