[Class 74 (ii)] Loops of thread B<1> are inserted as weft threads in the knitting of tubular fabrics to form a reinforced panel in an elastic fabric or an elastic panel in an inelastic fabric. The fabric is knitted upon a cylinder-and-dial machine, as described, a machine having a stationary needle cylinder and dial, and the weft thread B is carried up the interior of the needle cylinder A and out through an opening C. The thread B passes from the opening C to an eye in the top of an instrument D mounted in one of the needle tricks, and the yarn is seized and taken around the cylinder as a loop by a hook J<1> mounted upon the cam case. The hook J<1> is rotatable with a spindle J carrying a pinion J<2> which engages a segmental rack K<1> carried by an arm K. In the rotation of the cam case, the arm K engages an abutment L to rotate the pinions J<2> and to cause the hook to release the loop B<1>. At the point of release of the loop, a rib needle S is projected to hold the end of the loop and subsequently to draw a loop of the ground thread through it to lock it in the fabric. By providing long rib needles in the whole of the panel area, the two lengths of thread comprising each loop B<1> are disposed so that one length is positioned between the rib needle and cylinder needle loops of one course and the other length is positioned between the rib and cylinder loops of the next succeeding course. The thread B is tensioned by passing between jaws M<1> carried by a lever M and engaging a conical member Q. The lever M is depressed at the completion of each loop inserting operation to release the thread. Specification 455,931 is referred to.

Title: Improvements relating to the manufacture of graphite
Inventor: JENKINS MANSELL JOHN
IPC: C04B35/532
Filed: 1962-07-09
Abstract: A solid or plastic cokable substance, e.g. coal tar pitch, a petroleum bitumen, a bituminous coal or a pure hydrocarbon is coked by heating, preferably to about 500 DEG  C., while static in a still at a pressure sufficient to preserve the solid or plastic phase, e.g. up to 800 p.s.i.g., cooling and comminuting; calcination may precede or follow the comminution step.  The coke particles produced are roughly spherical or equiaxial and may be further shaped by mechanical abrasion. In the example, pure anthracene is coked by heating to between 500 DEG  and 550 DEG  C. at a rate not exceeding 15 DEG  C. per hour or at a pressure of N2 or A of 500 p.s.i.g., and maintained at 500-550 DEG  C. for 1 hour, excess pressure build-up being prevented by periodic release of the liberated volatiles; the cooled mass is crushed, milled and calcined and may be graphitized to yield a product of high isotropy.ALSO:Graphite of high isotropy is obtained by graphitization of coke particles produced in a process in which a solid or plastic cokable substance, e.g. coal tar pitch, a petroleum bitumen, a bituminous coal or a pure hydrocarbon is coked by heating while static in a still at a pressure sufficient to preserve the solid or plastic phase.  In the example pure anthracene is coked between 500 DEG  and 550 DEG  C. for 1 hour at 500 p.s.i.g. N2 or A, the heating rate to 500 DEG  C. being not more than 15 DEG C. per hour.  No details of graphitization are given.
