Title: Process for producing carbon fibres from mesophase pitch
IPC: D01F9/14
Filed: 1974-12-10
Abstract: 1496678 Carbon fibres from pitch UNION CARBIDE CORP 10 Dec 1974 [11 Dec 1973 (2)] 53251/74 Addition to 1416614 Heading C1A [Also in Division C5] High modulus, high strength carbon fibres are produced by spinning carbonaceous fibres from a non-thixotropic carbonaceous meso-phase pitch, the pitch having a meso-phase content of from 40% to 90% by wt. prepared by passing through the pitch an inert gas at a rate of 0À5 scfh per pound of pitch while forming the meso-phase by heating the pitch in an inert atmosphere, thermosetting the fibres so produced by heating in an oxygencontaining atmosphere to render it infusible, and carbonizing the thermoset fibre by heating it in an inert atmosphere. Suitable meso-phase pitches are produced by heating to 350‹ to 450‹ C. while passing the inert gas through the pitch. Typical inert gases are N 2 , Ar, Xe, He or steam. Alternatively the meso-phase pitch is formed by subjecting the pitch to a pressure of less than 100 mm. Hg while heating. The fibres may be thermoset in air at from 250‹ to 400‹ C. (e.g. for 5 to 60 min. at from 275‹ to 350‹ C.). Carbonization in an inert atmosphere such as these listed above may be effected by heating the fibres in excess of 1000‹ C., typically from 1000‹ to 2000‹ C. for 0À5 to 25 mins. It is also preferred to pre-heat the fibres at 700‹ to 900‹ C. for say, 0À5 to 5 mins., prior to the final carbonization. The carbonized fibres may be further heat treated at from 2500‹ to 3300‹ C. in an inert atmosphere (e.g. as above) for 10 sec. to 5 mins. to graphitize the fibres.

Abstract: 1,133,510. Autocondensation of acetone. SHAWINIGAN CHEMICALS Ltd. 19 Dec., 1966 [27 Dec., 1965], No. 56656/66. Heading C2C. Condensation products of acetone, e.g. diacetone alcohol, isophorone and mesityl oxide are obtained by mechanically dispersing an acetone immiscible aqueous solution of an alkali metal hydroxide in liquid acetone to form a reaction mixture of a stable fine dispersion of the catalyst in the acetone, and subsequently maintaining the dispersion at appropriate reaction temperatures for the time necessary for the desired autocondensation. Suitably acetone is condensed in the presence of the finely dispersed alkali metal hydroxide catalyst for between 5 minutes and 5 hours, to give as the principal product (a) diacetone alcohol at - 20‹ to 50‹ C., (b) mesityl oxide at 60‹ to 120‹ C. and (c) isophorone at 130‹ to 235‹ C. The catalyst may be an aqueous solution containing 25 to 50% by weight of an alkali metal hydroxide dispersed in acetone so that the mixture contains between 0À001 and 0À5% of alkali metal hydroxide. The catalyst may be dispersed in acetone (a) by passing the liquids together through a constriction which creates a pressure drop of from 20 to 200 lb./in.<SP>-2</SP>, (b) by using an ultrasonic generator or (c) by using a centrifugal pump.

Abstract: 1,166,522. Locks. LIQUIDONICS INDUSTRIES Inc. 21 Dec., 1966 [22 Dec., 1965], No. 57222/66. Heading E2A. A magnetic lock device comprises one or more tumblers 20, 21, 24 of ferro-magnetic material and a key 18 having magnetized inserts, 20", 32", 21", 31" and 24", one for each tumbler, adapted to cause all the tumblers to move from locking to unlocking position against the attractive action of auxiliary elements 20', 21' and 24', one for each tumbler acting, in the absence of the key, to move and hold its related tumbler into locking position, such movements being effective regardless of the line and direction of movement of the tumblers to unlocking position, and including non-magnetizable material 44 between each tumbler and its related auxiliary element. As shown in which the tumblers control a barrel 16 rotatably mounted on a cylinder 15, the tumblers are manually held in a locking position by the magnetic attraction of the auxiliary elements 20', 21', 24' constituted by permanent magnets. A second set of tumblers 31, 32 and elements 31' is arranged at an angle to be first set and the key 18 is provided with corresponding inserts 31" and 32". A pin 33 extending through the key is engageable at one end 33' thereof in an external channel 35 of the cylinder, and in a notch 36 in the barrel to prevent withdrawal of the key except when the tumblers are in the position in which they are moved to the locking position as the key is withdrawn. A tumbler 40 of a magnetizable material is normally maintained in a hole 41 in the cylinder by a permanent magnet 42, but falls into a socket 43 to block movement to the barrel if a magnetic kicking device is applied to the key-hole of the lock. In alternative arrangements Figs. 7 and 8 (not shown), the tumblers may be permanent magnets and the elements 20', 21', &c. unmagnetized and the material 44 may be air. In a further arrangement, Fig. 10 (not shown), the elements 20', 21' &c. are afforded by a soft-iron sleeve (52), and the material 44 is a copper or brass lining 52'.
