Abstract: 939,319. Knitting machines &c. M. S. MORETTA. Nov. 15, 1960 [Dec. 16, 1959], No. 39137/60. Class 74 (2). A sinker P 1  for a circular knitting machine has in addition to the usual neb 1 and throat 2 a second neb 8 and throat 9 at the same level. The first neb 1 is employed only for the formation of the first course of loops and acts, after the needle 10 has pulled the thread down into the throat 2, to prevent the needle dragging the loop upwards, the needle working in the usual way in front of said neb. For the subsequent courses the second neb 8 only is employed, the needle working behind this neb which functions to calibrate the loop size.

Title: Nuclear reactor fuel assembly
IPC: G21C3/338
Filed: 1974-09-11
Abstract: 1450878 Fuel elements V V KURILKIN and E V KUSMARTSEV 11 Sept 1974 39542/74 Heading G6C A fuel assembly comprises a plurality of elongate fuel elements at least some of which are provided with helically wound spacer members, each of which is formed as a bunch of wires. In one embodiment, as shown, each bunch comprises three wires 15, 16, 17, each of which initially adjoins the other two along their entire length. Wires 15, 16 constitute the base of the bunch adjoining the jacket of the fuel element 11  on which they are mounted, the third wire 17 being disposed externally in the space defined by the wires 15, 16, and adjoins the adjacent fuel elements 11. The wires 15, 16, 17 are rigidly interconnected by welding only between lines 18 drawn horizontally through the fuel element 11 from the points of contact with adjacent fuel elements. In the course of operation, the fuel elements undergo swelling and the resultant transverse stresses cause the spacer members to be deformed, the external wire 17 separating the wires 15, 16 at the points lying at the ends of the lines 18 and entering into the space thus defined (Fig. 8, not shown) thereby causing a reduction in the contact stresses of the jackets of the fuel elements induced by the spacer members. In their turn, the wires 15, 16 tend to eject the wire 17, thereby imparting elasticity to the spacer member as a whole so that it continues to exert on the adjacent fuel elements 11 the force required to keep them uniformly spaced along the entire length of the fuel assembly. In an alternative embodiment (Fig. 6, not shown), the spacer member comprises an increased member, e.g. six, of wires of reduced diameter and is consequently of increased lateral compressibility.

In a method and apparatus for the continuous electrochemical measurement of the concentration of a substance, such as sulphur dioxide in the atmosphere, the gas introduced through pipe 4, is brought at a constant speed into contact with a flowing solution 7 reactive with the substance to be measured, and the solution is electrolysed by at least two electrodes 2, 3 one (2) of which may become polarised and in the vicinity of which intensive bubbling is employed to ensure that practically all the electro-chemically active substance produced in the solution by the reaction with the substance in the gas is oxidised or reduced, the current during electrolysis being measured to provide an indication of the concentration. Air passed in tube 4 at a speed of 0. 5-1 litres per minute mixes with a 10% acqueous solution of sulphuric acid saturated with iodine passing along tube 5 at a speed of . 05-1 mL per minute from a vessel 10 filled with iodine crystals and the reaction produces iodide ions which are anodically oxidised at a platinum electrode 2. An equivalent amount of bichromate ions are reduced at an electrode 3 which extends into a depolarising agent comprising crystals of Potassium bichromate. The method is said to be suitable for the determination of the concentration of Chlorine, ozone or oxygen.
