A device, for use in conjunction with a statorwinding machine, comprises a plurality of mould pairs for guiding the wire and forming the coil ends, the moulds of each pair co-operating and being mountable at the respective stator ends during the forming of a coil, is characterized in that each mould has a projection for insertion axially into a stator slot and has one half of a plug-in coupling for fixing the mould by movement parallel to the stator axis and is further characterized in that the device comprises two holders, mountable outside both stator end surfaces and axially movable relative to the stator, and each adapted to hold a plurality of moulds, and having gripping means for dismounting the moulds from a stator by axial movement. Each mould comprises a guiding surface 1 along which the wire slides into a recess 2. Pegs 4 and 6, Figs. 1 and 2 (not shown), occupy one stator slot and pegs 3 and 5 occupy a second slot. The moulds are fitted by holes 9 on to pegs 18 of a holder 13, and have recesses 10 which are engaged by a rotatable pawl 14 when the moulds are to be removed from the stator 11, which has a casing 16 and laminations 17.

Title: Improvements in or relating to electrically driven chronometric balance mechanisms
Inventor: ALEXANDER BRUCE GODFREY
IPC: G04C3/06
Filed: 1954-12-02
Abstract: 781,781. Electric clocks. CASS & PHILLIP. Aug. '4, 1955 [Dec. 2. 1954], No. 34952/54. Class 139 In an electric chronometer the balance is electro-magnetically maintained by a maintaining circuit including a main electro-magnet and a switch .operated by movement of the balance staff. An auxiliary electro-magnet fed from the same supply as the main electro-magnet controls the position of a finger which when the supply is disconnected arrests the balance in a position wherein the hair spring is stressed so as to ensure immediate starting upon re-connection of the supply. The balance 22, Fig. 2, is carried by a staff 19 which also carries the armature 27 which is periodically impulsed by the electromagnet 28 upon closure of a switch comprising a contact element 25 on the staff 19 and a flexible contact 33 which is positioned beside a rigid lever 35 so that a long impulse is given to the balance as it swings in one direction and a short ineffective impulse as it swings in the other direction. An auxiliary electro-magnet 39 located adjacent the main electro-magnet and connected to the same supply has an armature 43 to which a curved 'finger 38 is attached When the supply is disconnected by opening of a main switch (not shown) a spring member 45. Fig. 1, moves the armature 43 so that the finger 38 moves the armature 27 and locates the balance staff 19 in a position in which the hair spring 23 is stressed. If desired this arrested position of the balance may coincide with engagement of contacts 25, 33. When the supply is again connected, the auxiliary electro-magnet is energized, the armature 43 is attracted against the pressure of the spring 45 and the finger 38 is moved away from the armature 27 so that the balance starts to oscillate. To avoid sparking between the contacts 25, 33 a resistor is shunted across the winding of the main electro-magnet.

Title: Nuclear reactor

Filed: 1975-09-03
Abstract: 1505577 Reactors WESTINGHOUSE ELECTRIC CORP 3 Sept 1975 [4 Sept 1974] 36209/75 Heading G6C A reactor, particularly of the sodium-cooled fast-breeder type, has, as part of the lower internals, a massive supporting structure 191 for supporting the core assemblies 121. The structure 191 carries the weight of the core assemblies 121 and their components and serves to distribute the heat-exchange fluid to the core and the other parts of the reactor vessel 21; it also transmits the forces of the weight which it supports, of the hydrostatic pressure of the fluid and of any seismic loads to the reactor vessel 21. The structure 191 has a massive plate 193 in which inlet modules 221, 223 which support, and distribute fluid to, the core assemblies 121 are removably mounted in openings 195. Each opening 195 has a liner 203 open at the top to receive a corresponding module 221, 223, and closed at the bottom to provide a low pressure plenum below the module and thus balance the hydrostatic forces of the fluid on the module so that the module is not ejected from the plate. The liner 203 is held mechanically in the plate 193 between a shoulder 300 engaging the bottom of the plate 193 and a collar 207 engaging the top of the plate. The collar 207 is welded to the liner 203 by a circumferential weld 228 which on solidifying pre-tensions the portion of the liner 203 between the collar 207 and the shoulder 300 and prevents the collar 207 from becoming loose on the liner 203 as the result of thermal transients. The opening 195 in the plate 193 in which each liner 203 is inserted is counterbored to provide an annular space between the plate and the liner in which heat-transfer fluid entering and leaving through holes 197 in the wall of the counterbore can flow around the liner. The massive plate may be formed in two parts: a massive inner disc and a massive ring secured to the plate by webs which take up the shear stress between the disc and the ring produced by the loads on them (Figs. 6A-6C, not shown).

Yarn from bobbins 1 is supplied to the needles of a knitting machine at substantially uniform tension by depressing the yarn 2 between fixed guide members 3, 4 to form storage loops, the yarn being clamped by brakes 5, positioned between the needles and the loops, when the needles are inactive so that increased tension during the loop-forming is not passed to the needles. The loops are formed by a grid-like frame 6 reciprocated by means of an eccentric 27 driven from the main machine drive and synchronized so that downward movement of the frame to form a loop takes place when the needles are inactive. The brakes 5 (see Fig. 3) comprise adjustable eyelets 11-14 for varying the yarn tension, a feed roller 15 around which the yarn is lapped at least once, and a double-armed spring 17, 18 which can frictionally engage a braking disc 16 to stop the feed roller when backward tension is applied to the yarn 2 by the loop-forming frame 6. When the needles are moving, the tension of the thread upon exit eyelet 23, mounted on the end of an arm 22, lifts the spring arm 17 from the disc 16. Braking pressure is adjustable by nut 21 working on screw 20.
