Title: Auxiliary device for controlling the action of patterning drums of knitting machines
IPC: D04B15/66
Filed: 1962-09-05
Abstract: 1,014,177. Knitting machines. SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTVI. Sept. 5,1962 [Sept. 5, 1961), No.33975/62. Heading D1C. Pattern control means for a multi-feed superimposed rotary cylinder knitting machine comprises a main control drum 2 with cam projections 3, 4, 5 co-operating with a series of follower levers 13 which act through nose pieces 17 and levers 19 to operate Bowden cables 22 to bring into operation pattern drums (not shown) associated with the knitting stations. During the start of the work and while knitting plain courses the followers 13 rest on drum 2 and the pattern drums are out of action. For patterning the drum 2 is rotated to cause the cams 4 to lift the followers 13 and so bring in all the pattern drums through a certain amount of movement of the Bowden cables 22. If for the execution of the pattern it is required to stop one of the pattern drums, an auxiliary control drum 53 is brought into action by a controlling stud 8 of a main pattern chain 7 on a sprocket 6 co-axial with the main control drum 2. The stud 8 lifts a follower 30 of a two armed lever 27, 28 which, through a Bowden cable 35, brings a ratchet pawl 90 into action to step round drum 53. Drum 53 has cam projections 60 which co-operate with follower levers 71a-a which are coupled by Bowden cables 76 to the followers 13 of the main control drum 2. Thus on the appropriate follower of drum 53 being lifted the corresponding follower of drum 2 is raised off cam 4 to a position to actuate cable 22 further to cut out the desired pattern drum. The stud 8 releases follower 30 on continued rotation of chain 7 so that the driver of auxiliary drum 53 is stopped and knitting continues with the remaining pattern drums only. If a further pattern change is required another stud 8 of pattern chain 7 is brought into action to effect another stepping of auxiliary cam 53 to cause another pattern drum to be cut out and the one which was previously cut out may be brought back into operation. Thus an over-riding control of the main drum 2 is provided. When required all the pattern drums may be cut out of action by rotating main control drum 2 so that the high cam 5 lifts all the followers 15 to the position where the cables 22 effect this operation a further movement of drum 2 to bring the followers 15 back on to the low cams 4 will bring all the previously active pattern drums back into operation. If the drum 2 is rotated so that low cam 3 engages a follower 29 of lever 27-28 the cable 35 and pawl 90 are partially actuated, the drum 53 being driven until a low tooth therein comes under pawl 90 which corresponds to the starting position of drum 53.

Abstract: 602,788. Lathes. NIELSEN, L. H. Dec. 15, 1945, No. 34002. Convention date, March 15, 1943. [Class 83 (iii)] In a lathe for cutting either tapered or straight screw-threads in wood, either internally as in broom stocks, or externally as on broom handles, the work is secured to a clamp attached to a hollow rotatable cylinder fed towards a rotating cutter by a screw and nut and capable of being displaced to one side by means of an inclined plane. A work head 4, Fig. 1, is mounted on pivots 2 on the machine frame 1 and carries a hollow cylinder 6 on which is cut a lead screw 7. The cylinder may be rotated by a handle 20 and bevel gears 21 or 22 or any other suitable drive and is fed forward when a spring-loaded half-nut 8 is engaged with the lead screw by depressing a pedal 9. When the half-nut is disengaged, the cylinder may be shifted by means of a handle 14 on a ring 16 loosely fitted between collars 15. A socket 30 on the cylinder carries either a pivoted holder 29 with an angular scale and a clamp screw 33 for holding broom stocks, or clamps 37, Fig. 5, for broom handles inserted through the cylinder. The holder 29 has a hole 34 so that the broom stock can be centred by a rod passed through it into the hole already formed in the stock. For cutting taper threads, the work head is moved sideways against the action of a spring 50, Fig. 2, as the cylinder is moved forward by a roller 18 on the ring 16 engaging an inclined guide 19, the roller arm being fitted between guide rails 27. An arm 25 mounted on pivots 26 carries the cutter spindle which is driven by a pulley 46. The arm 25 is moved up into working position against the action of a spring 45 by the pedal 9 which is connected to a rod 44 abutting on the arm by means of a shaft 10 and rods and levers. The movement of the arm is limited by fixed stops or by screws 38, 39. The cutter 47, Fig. 6, for external screw cutting has auxiliary blades 48 fitted in front of it for removing surplus material when cutting taper threads. The cutter 23, Fig. 2, for internal threads is four-fifths of the diameter of the hole to be threaded.

Title: Improvements in or relating to the manufacture of uranium/zirconium carbide
Inventor: WHEATLEY CHRISTOPHER CAMERON H
IPC: C01B31/30
Filed: 1962-09-06
Abstract: A solid solution of U/Zr carbide is produced by taking a mixture of uranium carbide and zirconium carbide in the requisite proportions, grinding such a mixture to a particle size of less than 5 microns in an atmosphere in which oxygen bearing materials are substantially absent, pressing the ground mix at a pressure in excess of 5 tons/square inch and heating in one or more stages in vacuo to a temperature in excess of 1800 DEG  C., oxygen being excluded at all times until completion of firing.  The concentrations of oxygen and water in the atmosphere are preferably less than 30 and 150 parts per million respectively. The uranium and zirconium carbide may be obtained by co-formation from the corresponding metal or metal oxide and the carbides are preferably ground with a vibro milling machine for a period of 7-20 hours. The ground powders may be pressed isostatically at 100,000 lb./sq. inch and heated in one stage to 2100 DEG  C. or in two stages first to 1400 DEG  C. and then to 2100 DEG C., and during heating the pressure is 10-4 tons.  A preferred product contains 67% by weight UC and 33% ZrC and, if desired, the uranium may be enriched in 235. The product may be utilized as a nuclear fuel material but its primary purpose is the direct conversion of fission heat into electric power.
