Abstract: 1,107,290. Thread-break. PALITEX PROJECTCO. G.m.b.H. 24 Oct., 1966 [25 Oct.. 1965], No. 47592/66. Heading DID. A thread brake, Fig. 1, for 2:1 twisting apparatus comprises a housing 1 which is insertable into a bobbin holder and which carries a thread-guide tube 13 and a pair of axially - spaced brakerings 2, 4 with a brake cartridge 3 between them; the upper brakering is carried by a ring 5, the axial position of which in the housing can be adjusted by engaging a fixed stop 7 with a selected one of a number of surfaces located at different levels on the ring 5. The cartridge 3 may be a single member with upper and lower rounded ends or, as shown, two telescopically-slidable members each with a rounded end and with a spring between them. The ring 5 is secured to the tube 13, and is loaded by a spring 13 bearing at its upper end against a collar 12 removably secured to the housing and slidable on the tube 13. The surfaces which cooperate with the stop 7 to position the upper brake ring are constituted by the ends of slots (6a, 6b, Fig. 2, not shown) having curved sides and different depths; by turning the tube 13, the ring 5 can be rotated until a selected one of the slots engages the stop 7, thus changing the degree of compression of the spring 11, to vary the load on the upper brake-ring. The load is indicated by which one of a series of marks on the tube 13 becomes level with the stop 7. of which a lug 8 engages a recess (9) in the bobbin carrier (10, Fig. 3) to position the housing relatively to the bobbin carrier. The carrier has one or more openings 14 through which the cartridge can be observed and replaced by one containing a spring of different characteristics. In alternative arrangement, the carrier 1 is in two parts connected by asymmetricallyspaced curved plates or rods, which to locate the carrier are engaged with correspondinglylocated recesses in the bobbin carrier. The lower brake ring may be supported on a spring as described in Specification 1,107,289.

A charge shoot for serving two circular groups 15, 16 of fuel element guide tubes arranged concentrically about a support 18 comprises a tubular body 10 having a leg 11 pivoted thereto at 12. A stem 13 projecting from the body 10 is non-rotatably supported by the support 18, is rotatable relatively to the body, and has keyed thereto a drum-type cam 32 having two tracks 41, 42 shown in developed form in Fig. 7. A bell-crank lever 34 pivoted at 36 to the body 10 has a cam follower 37 which engages the track 41 or 42 and also has a pin 39 connected to the leg 11. The tracks 41, 42 are connected by inclined tracks 43, 44 and have steps 45, 50. In the solid-line position in Fig. 1 the follower 37 engages track 41 so that as the shoot is rotated the leg 11 moves over the inner group 15 of fuel element guide tubes. When the follower 37 reaches the step 45, reversal of the rotation of the shoot causes the follower to move along track 43, whereby the lever 34 pivots into the chain-line position in Fig. 1 and the leg 11 is moved to be above the group 16 of fuel element guide tubes. When the follower 37 reaches the track 42 the direction of rotation of the shoot is again reversed so that leg 11 moves over the outer group 16 until the follower reaches the step 50. The follower 37 now moves along the track 44 to the track 41 and the leg 11 is returned to its initial position above the group 15.

[Also in Divisions Fl and F2] A diesel hammer comprises a ram 2, an anvil 3 and a cylinder housing 1 defining a combustion chamber 5 and a fuel pump 7 operated by the air pressure within the chamber 5. The fuel is supplied from a tank 6 around the cylinder and pumped along lines 12, 13 to fuel injection nozzles 8, 8<SP>1</SP>. The pump 7 comprises a piston 31, Fig. 12, which when reciprocated closes the fuel duct 29 and forces the fuel through a non-return valve 35. The piston 31 is moved by a push-rod 27 operated by compressed air in a chamber 24 connected by a passage 14 to the combustion chamber. In operation, the ram 2 falls under gravity to compress the air in the chamber 5 and actuate the fuel pump 7. The fuel injected into the chamber 5 is ignited by the air which has been heated adiabatically. The ignited fuel causes further movement of the fuel pump piston 31 and the injection of more fuel. The fuel injection nozzles 8, 8<SP>1</SP> may direct the fuel over an angular distance to each side or one side of the nozzle axis, Figs. 6 and 7 (not shown). A valve (54), Fig. 13 (not shown), may be provided in the fuel line from the pump to the nozzles. The valve is spring-biased open and closed by rope-actuated levers (52), (53).
