Abstract: 707,985. Knitting-machines. MELLOR, BROMLEY & CO., Ltd. Aug. 21, 1951 [Sept. 12, 1950], No. 22409/50. Class 74 (2) i Yarn severing and trapping mechanism is provided adjacent the needle circle in a circular machine and is adapted to be operated in conjunction with the movement of the yarn guides from their operative and inoperative positions. As described in connection with a single cylinder circular machine, the mechanism comprises two series of fingers 15 rotatable about a common axis 17, the fingers operating in pairs to trap and sever the yarn cf a withdrawn guide by one of the fingers engaging the yarn and drawing it through a trapper in which the yarn is held, and the other finger co-operating with a cutter associated with the trapper to sever the yarn. The fingers 15 are formed as part of rotatable discs 13, 14 adapted to be periodically rotated by a pawl 30 engaging pins 16 securing the discs together. The movement of the pawl 30 is derived through a lever 27 from a cam on the sinker ring 3. This movement is controlled by a lever associated with the ratchet mechanism rotating the drum controlling the thread guides such that only when the drum is rotated to effect a change of guides is the pawl 30 operated. When rotation of the discs is effected, the finger of the disc 14 becoming operative. upon the movement and being slightly in advance of the corresponding finger of the disc 13, engages the yarn of the withdrawn guide and passes through the fixed and sprung jaws 19, 20 of the trapper so as to cause the yarn to be held therebetween. The following movement of the finger of the disc 13 draws the yarn against the edge 25a of a cutter 25 fixed to the trapper and thereby severs the yarn. At the next yarn change the following pair of fingers become operative, the discs rotating in one direction only and each pair of fingers becoming operative in succession. The invention may also be applied to a cylinder and dial machine and to a double axially opposed needle cylinder machine.

Abstract: 961,827. Nuclear reactors. ATOMENERGI A.B. June 6, 1963 [June 6, 1962], No. 22583/63. Heading G6C. A nuclear reactor comprises a thin-walled reactor tank containing a water space and a steam space, a pressure-resistant vessel enclosing the reactor tank, a gas filled space between the tank and the vessel, a communication between the steam space and the gas-filled space so as to equalise the pressures in the two spaces, means for withdrawing gas from the communication and removing any steam in the gas, and means for supplying the dried gas to the gas-filled space. In the boiling water reactor shown in Fig. 1 the reactor core is contained in a stainless steel tank 3 mounted within a steel lined concrete pressure vessel 1. The space 7 between the tank and the pressure vessel contains a gas, such as air or helium, which is in contact with steam generated in the reator through an opening 4 in the top of the tank. Steam-gas mixture is withdrawn from the space 7 through pipe 28 and taken to a condenser 29, where the water condenses out, and the dry gas is taken via a pump 30 into the bottom portion 16 of the pressure vessel and flows upward in space 7. The space 7 contains means 5 for supporting the tank and a thermal shield 6 comprising several cylinders of sheet steel. Feed water enters the reactor through a pipe 10 and steam generated in the reactor passes downwards through superheater tubes 12 to a header 13 and an outlet 14. The temperature or pressure in the reactor increases abnormally, a valve 24 is opened to allow steam to pass from header 13 to an expansion chamber 20; the latter is connected by a pipe 22 to a water vessel (not shown), the pipe including a safety valve 26. Valves 23 and 25 in the water inlet and steam outlet pipes may be closed in response to abnormal conditions in the reactor. Fuel is fed to and from the reactor of a loading machine 18 and a pipe 19, the fuel being handled inside the reactor by a manipulator 32 which can be inserted through the lid 2 of the pressure vessel. In another arrangement, Fig. 2, using heavy water, the steam space 39 has a pipe connection 41 to the gas space 40. The pipe connection contains a small storage vessel 47 and a narrow passage 48 which is shunted by a circuit containing a circulator 51 and a drying unit 52. The circulator maintains a flow of gas (e.g. nitrogen) in the direction shown by the arrows, and the circuit is connected to a high pressure gas storage vessel 55 by means of a compressor 53 and throttling valve 54. The concrete pressure vessel 37 is lined with blocks 56 of insulating concrete and contains cooling water pipes (not shown).
