Abstract: 1,253,169. Assembling electrical brushes; jointing by stamping; shearing. AMP Inc. 16 June, 1970 [24 June, 1969], No. 29060/70. Headings B3A, B3Q and B3W. A method of assembling a lead wire 2 of an electrical component through a spring 6 comprises, positioning the wire at one end of the spring and across the axis of the spring to form a bight in the wire, compressing the spring, locating a part of the wire emerging from the other end of the spring in a ferrule 332 of a terminal and securing the terminal to the wire, the bight being moved through the spring. The lead 2 is positioned manually in an eye 300 of a threading rod 298 after the spring 6 has been placed thereon, and a brush 4 for a dynamoelectric machine is disposed in a holder 384. The rod 298 is pulled through the spring and simultaneously the holder 384 is raised to the level of a spring holder 306 and brought into abutment with it, thereby compressing the spring. The wire 2 is pulled through a retainer plate 312, taking up an arcuate form as it moves through the eye 300 so that it is lightly retained by the plate. The operator then places the bared end of an insulated wire 324 above the ferrule 332. The ferrule is located on an anvil 316 and a carrier strip 328 of a strip (326) of terminals, Fig. 1 (not shown), is located in a slot 318 of a depressible shear block 320. A crimping die 322 is then actuated and on its downward movement the ferrule 332 is crimped to the wires 2, 324. At the same time, the shear block 320 is depressed, as the lower end of the die 322 engages a projection 512 on the shear block so that the terminal on the anvil 316 is sheared from the strip 328. After the die has moved through its return stroke, the brush 4 is ejected from the apparatus by a pivoted plate (494), which projects into the path of the holder 384 during its return stroke, Fig. 19 (not shown).

Abstract: 1288485 Explosively actuated fastener driving tools OLIN CORP 18 Feb 1970 7832/70 Heading B4C An explosively actuated fastener driving tool comprises a body member 1 in which a fastener driving piston 3 is reciprocable and in which a cylindrical member 8 is mounted for rotation between a loading and a firing position. The cylindrical member includes a diametrical bore 9 for receiving a cartridge or other explosive charge, e.g. a pellet of explosive material, and when the member is in the loading position the bore 9 registers with an opening 11 through which a cartridge or other charge may be introduced into the bore and with a bore 12 through which an appropriate tool may be introduced to eject a spent cartridge from the bore. When the member is in the firing position, the bore is aligned with a firing pin 14 and with a port 13 leading into a cylindrical space 2 in which the piston reciprocates. The member 8 is held in the body member against axial movement by screw plugs 19 which also act as gas seals, and is rotatable by a handle 18. A pin 15 in the body member engages a slot 16 in the member 8 and the ends of the slot define the loading and firing positions. A lever 25, pivotally mounted on pin 26 and located in a recess 27, in the body member, is normally urged by spring 28 to the inoperative position of Fig. 3. With the lever in the inoperative position a blow applied to end wall 21 of the cap 22 will not drive the firing pin 14. Rotation of the cap anticlockwise (Fig. 3) relative to the body member will cause a pin 31 carried by the cap to move the lever 25 to an operative position overlying the firing pin such that a blow then applied to the cap will effect firing of the cartridge or explosive charge.

Abstract: 1297496 Rod seals UNITED STIRLING (SWEDEN( AB & CO KB 3 Sept 1971 41151/71 Heading F2B A seal for the piston rod 3 of a hot gas engine comprises a first wall 8 adjacent the high pressure side 7 of the seal, a second wall 9 adjacent the low pressure side, a third wall 10 which is axially-movable between the first and second walls, means such as a gas return conduit 15 and non-return valve 16 for establishing in the space between the first and third walls a pressure corresponding to a minimum pressure occuring at the high pressure side 7, and means such as an oil pump 18 and oil escape passage 19 for establishing in the space between the third and second walls a pressure substantially equal to the pressure in the space between the first and third walls. During operation, the gas leaking past the wall 8 is compressed by the upward force of the wall 10 as oil is supplied from the engine sump by the pump 18, the pressure of the gas being established at the lowest cyclic pressure in the chamber 7 by the non-return valve 16 in the conduit 15. The upward movement of the wall 10 ceases as soon as the inlet port to the oil escape passage 19 is uncovered to allow a sufficient rapid leakage of oil back to the sump; an effective seal is thereby provided by the wall 10 since there is almost no pressure difference across it. When the engine is stopped, oil is no longer pumped to the space between the walls 9, 10 and the gas pressure urges the wall down on to a rubber gasket 22 which becomes compressed against the rod. The wall 8 is arranged to be radially-movable and an oil-separator 17 is provided in the conduit 15.

Abstract: 1304467 Valves ENGINEERING LABORATORY EQUIPMENT Ltd 12 Oct 1971 [10 Nov 1970] 53449/70 Heading F2V In a needle valve comprising a needle 6 having a conically tapered portion 8 which extends into a conioally-tapered bore and a more steeply tapered point 19, the needle being movable axially relative to said box by rotation of a shank 11 which is in screw-threaded connection with a body 1 of the valve but being prevented from rotation, the needle is attached to the shank in such a way that the needle has a limited freedom of lateral movement relative to the shank. This is achieved by providing the needle with a head 13 which is held in a blind bore of the shank by a nut 14, the axial thrust being transmitted through a ball bearing 15. The lateral movement is limited by cylindrical bores in the nut and in sleeve 3. The conical bore is provided in sleeve 4. Rotation of the needle is prevented by the sealing ring 9 which also prevents flow between the needle and sleeve 3. The sleeve 4 is also provided with a sealing ring 5. The shank is provided with a stop 18 so that the needle does not come in contact with the bore in sleeve 4. The needle has a core tip with a greater angle of conicity than the portion 8. The sleeve 3 is provided with grooves 20 and the body with an annular chamber 21 to facilitate the even flow of fluid to the output port 22.

Apparatus for the method comprises a base-plate 11 having a reaction member 12 supporting the hollow pressure vessel 15 comprising a rigid back member 17 spaced from a neoprene rubber diaphragm 18 by a peripheral rubber member (19) Fig. 2 (not shown), bonded to both parts, an additional peripheral clamp is also provided for this purpose. Pressurized fluid delivered, through inlets (24, 25), to compartments of the pressure vessel divided by an extensible rubber partition wall 21 inflates the diaphragm and so causes varying loads, according to the fluid pressure, to act on the surface element 10 e.g. a missile wing, supported above vessel 15 on one side by bracket 16 and on the other by an angle member 29. The latter also prevents sidewards bulging of the inflated diaphragm. The amount of deflection is measured by gauges 26 through feelers 28 and for simulating pressure loads in high speed flight, the element surface temperature may be increased by infra-red heaters 27.

The elastic ring 12 may be a rubber ring or a metallic spring. When an impact is applied to the steering assembly the elastic ring 12 is stretched to allow the upper component to move down the shaft 9. In a first embodiment (Fig. 2) the detent members 6 are pivoted by pins 7 to lugs 5 formed on an enlarged portion 3 of the tube 2 which carries the steering wheel (not shown). Each groove 10 may be formed with a plurality of dents 11 as shown in Fig. 2. Alternatively each groove 10 may be formed with one dent 11 at its top end and the remainder of the groove is smooth. This remaining portion of the bottom wall of each groove may be parallel to the axis of the shaft 10 or may be inclined so that the elastic ring 12 is progressively stretched as the tube 2, 3 moves downwardly. In a further modification the tube 2 is formed with an extension (not shown) which is co-axial with the enlarged portion 3 and which is slidable inside the hollow shaft 9. The extension has an axial groove and the shaft 9 has a key engaging the groove to prevent relative rotation of the tube 2 and shaft 9. In a second embodiment (Fig. 10) the detent members 6 are pivoted by pins 21 to lugs 20 formed on the steering wheel rim 1.
