Patent GB-470292-A (GB)
Title: Process for the manufacture of highly nitrated and stabilised cellulose nitrates
IPC: C08B5/02
Filed: 1936-04-07
Abstract: Stable cellulose nitrates with high nitrogen contents are obtained by treating cellulose with a mixed acid containing nitric acid, phosphoric acid and phosphoric anhydride, removing and washing out the acid from the resulting cellulose nitrate, boiling the latter once or several times with a reagent which exerts a swelling but not a dissolving action on the cellulose nitrate, and finally removing the swelling agent from the cellulose nitrate. If desired, small amounts of hydrochloric or perchloric acid may be added to the swelling agent.  In an example, cotton linters in a finely divided state produced by stirring in ethanol or methanol and subsequent treatment with ether, gasoline, or dichloromethane, or in the form of thin sheets, are treated with a mixture of phosphoric acid and nitric acid containing free phosphoric anhydride for 2--10 minutes at 0--50 DEG  C.  When nitration is complete the waste acid is separated, and the material after washing is heated to boiling with ethanol with or without addition of soap or similar higher fatty acid compound. Aqueous acetone may be used as swelling liquid instead of ethanol. The swelling liquid may then be removed by centrifuging, filtering or washing.  Cellulose nitrate containing up to 14 per cent of nitrogen may be obtained.  In another example, textile fabrics which have been boiled in weak alkali to remove fatty substances, or artificial silk fabrics are treated with a mixture of nitric acid, phosphoric acid and phosphorus pentoxide.  Air bubbles may be removed by passing the fabric through rollers or by vacuum treatment.  The mixed acid may flow in counter-current to the direction of travel of the fabric. The material is stabilized by treatment with alcohol or aqueous acetone maintained at the boiling point.  The cellulose nitrate produced may be employed in explosives particularly for cartridge case charges, and in making filter cloths for filtering acid liquids such as a mixture of gypsum and phosphoric acid, or phosphoric acid containing sulphuric acid and iron salts.

Title: Improvements in Knitting Machines.
IPC: D04B1/28
Filed: 1919-04-24
Abstract: 126,616. Hemphill Co., (Assignees of Bosworth, G. P.). May 8, 1918, [Convention date]. Circular machines; knitting, methods of. -- Gloves are knitted on circular latch-needle machines having a rotating needle cylinder (1) by ma.king a tubular fabric to form the wrist up to the root of the thumb, (2) reciprocating the needle cylinder and knitting on a portion of the needles only to form a thumb strip. (3) throwing all the needles into action and again knitting tubular fabric to form the hand up to the roots of the fingers, and (4) knitting separately and in succession on groups of needles by reciprocation of the needle cylinder six rectangular strips of fabric to iorm (a) the whole of the first finger tube, (b) the outside half of the second finger tube, (c) the outside half of the third finger tube, (d) the whole of the little finger tube, (e) the inside half of the third finger tube, and (f) the inside half of the second finger tube. It will be seen that the thumb strip forms a loop of fabric continuous with the tubular fabric at its ends. The sides of this loop are united by seaming to form the complete thumb tube. The longitudinal edges of the rectangular strips to form the first and little fingers are seamed together to form complete tubes. The pairs of strips which form the outside and inside halves of the second and third fingers have their longitudinal edges seamed together to form tubes. In making four of the six strips which form the finger tubes, some of the needles, as shown diagrammatically in Fig. 8, are common to two groups, and, consequently, the strips made have overlapping edges. When the overlapping parts are severed at the base they form four gusset pieces which form the sides of the tubes for the second and third finger tubes. All these operations are performed on a known type of knitting- machine by means of knitting cams e<2>, e<3>, x, x and needle withdrawing and selecting cams 2, 3. 6, 21, 10, 15, 15a, 15<b>, 15<c>, 15d, Fig. 6. The cams are operated in a properly timed sequence by means of pattern mechanism and act on needles having variously positioned butts of various lengths in such a way as to throw the various groups of needles into and out of action as required. When making the thumb and finger strips by reciprocation of the needle cylinder it is necessary to bring each section of needles into a central position with respect to the fixed knitting cams and yarn guide. When the change motion causes the needle cylinder to reciprocate, the pattern mechanism causes the needle cylinder to be unclutched from its driving wheel, which goes on without the cylinder; after a certain amount of lost motion, the cylinder is again clutched to the reciprocating gear. This centralizing of the cylinder is controlled by the pattern mechanism.
