Title: Improvements in the method of and apparatus for punching strip iron
IPC: B21D31/02
Filed: 1924-03-20
Abstract: 223,493. Stachelband Ges. Jan. 8, 1924, [Convention date]. Wire.-In a process for making wire strip metal is fed between rollers p to dies f, a between which it is first perforated at n, Fig. 4, by punches h, Fig. 1 and then slit at o by parallel bent cutters e which are formed with clamped edges so as to bend the slit metal out of the plane of the strip. The tongues so formed coact with correspondingly chamfered members d so as automatically to eject the strip when it is fed forwards. A stripping-plate i is provided for the punches h. In a modification, the punched holes mav be elongated to extend to the centre of the strip. The slitting- cutters are so formed as to cut first at the edges of the strip.

IPC: H01J35/10
Filed: 1942-05-28
Abstract: 557,631. Magnetic brakes. BRITISH THOMSONHOUSTON CO., Ltd. (General Electric Co.). May 28, 1942, No. 7251. [Class 103 (i)] [Also in Group XL] An X-ray tube having a rotatable anode is provided within the envelope with magnetic braking means for bringing the anode to rest when the drive ceases. The X-ray tube shown comprises an anode support or pedestal 17 extending into the glass extension 21 to which it is sealed at 29 by a member 25, 27. The anode 11 is attached to a cylindrical member 15 of steel carried by a spindle 37 mounted by roller bearings 33, 35 within a tubular part 19 of the support 17. The bearings are positioned by members 39, 41 and may be lubricated in the manner described in Specification 542,665, [Group II]. The braking device comprises a permanent magnet 43 secured in a slot in the support part 19 by transverse straps which also form pole pieces 47, 49 slightly spaced from the steel part 15 which completes the magnetic circuit. The skirt 31 of the anode is of cuprous material and with the steel part 15 constitute the rotor of a motor device by which the anode is driven, the stator being formed by annular windings disposed about the tube extension 21 and which when energised establish a rotating field. The co-operation of the magnet 43 with the part 15 produces a braking action which rapidly brings the anode to rest when the windings are de-energised.

Title: Improvements in fuel injection apparatus for internal combustion engines
IPC: F02M57/02
Filed: 1948-03-09
Abstract: 677,324. Fuel injectors. AKTIEBOLAGET ATLAS DIESEL. March 9, 1948 [March 22, 1947], No. 7259/48. Class 7(iii) [Also in Group XXVIII] A fuel injection apparatus comprises a pump having a plunger 5 reciprocable in a cylinder 4 which communicates through a pipe 17 with a fuel injection valve 3, means in the plunger or cylinder providing a small accurately defined vent passage through which the fuel leaks during the initial part of the injection stroke to byepass the plunger, and an actuating cam 6 which has a relatively slow rise 7 for producing a preliminary injection and a relatively steep rise 8 for producing the main injection. The plunger has a peripheral groove 10 communicating with the pump chamber 11 through a small leak passage 12 which forms a restricted byepass from the pump chamber to the supply duct 13 until the latter is closed by the lower edge 16 of the groove. The fuel injection valve which is designed to open at a low pressure and to close against a high pressure, has its nozzle openings 19 controlled by a needle valve 18 having a large piston portion 20 and a small piston portion 21 both of which are subjected to the pressure of the fuel in chambers 32, 27 respectively to raise the needle valve against its loading spring 22. The fuel enters a gallery 24 connected permanently with the chamber 32 and, through a valve 25, provided with a pressure-reduction piston portion, with the chamber 27. A return flow passage 28 communicates with the gallery 24 through a check valve 29 provided with a pressure-reduction piston portion. The valve 29 is held closed by its spring 30 and the pressure in gallery 24 until the pressure therein is released whereupon the needle 18 closes and the valve 29 opens to permit excess fuel in the chamber 27 to escape. In another embodiment the pump and injection valve are formed as a single coaxial unit and the plunger has a slightly reduced end to form the vent passage. In other embodiments a vent plug is provided in the cylinder wall or a 'vee' notch is provided on one edge of a peripheral groove in the cylinder wall or in the end of the plunger. Specification 563,539, [Group XXVIII], is referred to. The Specification as open to inspection under Sect. 91, also discloses construction in which the vent passage is effective during the entire injection stroke. This subject-matter does not appear in the Specification as accepted.

Filed: 1958-03-10
Abstract: 918,913. Extrusion machines. COAL INDUSTRY (PATENTS) Ltd. June 10, 1959 [March 10, 1958], No. 7592/58. Class 87(2). An extrusion die 2 has a flexible inner wall that is under hydraulic pressure to decrease it in size at least part of the extrusion passage. The hydraulic pressure may be coupled to that of a ram 15 so that a constant pressure to the passage of extrusion is exerted, irrespective of ram pressure. In operation the ram 15, movable in and with a piston 10, is moved by the piston 10 to force the material through the passage. As extrusion pressure increase with ram movement a cam 19 opens a valve 20 to connect the fluid in a cylinder 11, behind the ram 15, with a spindle 23 of a valve 17. If the ram pressure exceeds that of extrusion the spindle 23 will lift a valve 26, against a spring 26 to exhaust the die through pipes 6, 28 to reduce extrusion pressure. If the ram pressure is less than extrusion pressure the spring 26 will move the valve 26 and spindle 23 downwards until a port 30 communicates with the pipe 6 so that fluid under pressure may be admitted, through the port 30, to the die to increase its pressure. Specification 875,441 is referred to.

Abstract: 1464131 Making shadow masks HITACHI Ltd 20 Feb 1974 [21 Feb 1973 4 July 1973] 7789/74 Heading B3A A method of making a shadow mask includes annealing a sheet of low carbon or mild steel, skin-pass rolling the annealed sheet to a reduction of 0À5-15%, forming holes in the sheet and press forming it to shape. The sheet material is annealed at about 600 C. for 20 minutes to give high elongation properties. The sheet is normally cold rolled but it may be rolled hot if desired. Rolling imparts high ductility and substantially nil elongation at the yield point. The sheet has holes formed by etching and is finally pressed to shape, normally cold but hot forming may be used. Skin-pass rolling the sheet material delays ageing so that the rolled sheets can be left several weeks between rolling and press forming

[Class 83 (iii)] A portable hand-operated tool for grooving pipes comprises a hollow body 1, means supported by the body for centring it on a pipe, a cutter 17 carried by the body 1 and having means for maintaining resilient pressure thereon throughout the grooving operation, and stop means for limiting the depth of feed of the cutter 17. The hardened-end 13a of a screw 13 centres the pipe against rollers 7 in the body 1 as the end of the pipe locates against a stop 40. The cutter 17, which is housed in a recess in the body 1, is attached by a pin 31 to a screw 22 passing through the end 20 of a cover member 12 which is attached to the top of the body 1. A wing-nut 23 on the end of the screw 22 retains the cutter 17 against the influence of a compressed spring 27 interposed between the cutter 17 and the end 20. An extension 35 of the pin 31 is guided in a slot 30 in a stop-member 29, the position of the member 29 being adjustable by releasing a clamp-screw 32 in the slot 30 and operating a setting screw 37 whose head is received in a recess in the cover 12. During the grooving operation, the body 1 is turned by a wrench 6 co-operating with teeth 3 formed in the side of the body. The wing-nut 23 is backed-off on the screw 22 to allow the tool 17 to be fed by the spring 27 until the extension 35 of the pin 31 encounters the end of the slot 30 in the stopmember 29. In a modification, the axes of the rollers 7 are inclined to advance the upper ends 11 of the roller axles 8 in the direction of rotation of the tool and so influence the stop 40 to bear against the end of the pipe as the tool is rotated.
