Title: Method and apparatus for machining articles using a beam of charged particles
IPC: B23K15/08
Filed: 1963-10-22
Abstract: 980,600. Cutting by fusion. NIHON DENSHI KABUSHIK KAISHA. Oct. 22, 1963 [Oct. 23, 1962], No. 41597/63. Heading B3V. [Also in Division H1] In the machining of a workpiece 1 by a beam 4 of charged particles, the workpiece is subjected to a magnetic or electric field to deflect the beam as it penetrates the workpiece. This enables curved cuts, grooves and bores to be formed. An ion or preferably an electron beam 4 which may be pulsed, is generated by a cathode 8 and anode 9 and focused by a condenser lens 10. A magnetic field is generated by coils 12, 12<SP>1</SP>, in pole pieces 2, 3 to act on the workpiece 1 which is mounted on a movable support 11. A shield 14 of high magnetic permeability protects the beam from the magnetic field. Various forms of curved bores, grooves and cuts are described, Figs. 4-7 (not shown). In one embodiment, Figs. 8, 9 (not shown) three sets of deflecting magnets may be used to produce reversely curved shapes, and in another embodiment, Fig. 10 (not shown) a helical bore is formed. The shape of the bore or cut can be varied by adjusting the speed of the electrons, the angle of the beam relatively to the workpiece and the strength and direction of the electric or magnetic field.

Abstract: 1439817 Generating gears MAAG GEAR-WHEEL & MACHINE CO Ltd 6 Sept 1973 [7 Sept 1972] 41960/73 Heading B3K  Apparatus for grinding the flanks of the teeth in a gear 4 by means of at least one grinding wheel 15, 16, wherein a generating motion between the workpiece 4 and wheel 15, 16 is modified so as to provide for a superimposed relative movement in the Z direction between the wheel and workpiece, comprises position transducers 8a, 27 responsive to relative movements between the workpiece and wheel, in the X, Y, directions and providing a measure of these movements, a programme control unit 30, receiving an input from the transducers, having means for comparing the input with a feed position programme and an output providing correcting displacements for the relative positions so as to modify the gear tooth involute profile. Workpiece 4 is rotatably mounted on a cross-slide 3 movable by a drive unit 11 comprising a crank 12, and the position transducer 27. The workpiece is rotated upon movement of the cross-slide, by tension tapes 6 connected to a pitch block 5, and a pitch block stand 7. Slide 3 is mounted on a carriage 2, moved by a unit 8 which comprises the position transducer 8a. Each grinding wheel 15, 16, is mounted on a shaft and the positions of the shafts are determined by stepping motors 25, 26, which pivot levers 21 when cams 24 are rotated, the levers then engaging the ends of the shafts and moving them, along with their grinding wheels, in the Z direction. Control unit 30 includes a keyboard 32, a programme selector switch 40, and displays 37, 38, 39, for the X, Y and Z co-ordinates. In operation, information including any desired deviation from an involute is fed into unit 30, and during the grinding operation signals relating to the positions of the grinding wheels, carriage 2, and cross-slide 3, are fed into unit 30 by transducers 8a, 27, 28, 29. The values are compared for each instant, and any difference provides for rotation of motors 25, 26, so as to move the grinding wheels in the Z direction. It is stated that the correcting movements in the Z direction can be applied to the workpiece rather than to the grinding wheels when only one flank is being ground at any one time. Keyboard 32 may be replaced by a punched tape, or the control may be by templates.

Abstract: 1,143,058. Fuel injection I. C. engines. DAIMLER-BENZ A. G. Sept. 14, 1967 [Sept. 15, 1966], No. 42010/67. Heading F1B. In a method of injecting fuel into a spark or glow plug ignited I. C. engine, in which the commencement of injection is advanced with an increasing quantity of injected fuel, the fuel initially impacts the piston 2, Fig. 1 at a point remote from the ignition source 7 and the region of initial impact moves across the piston head towards the ignition source as the piston rises, the fuel flowing across the piston head in a film-like manner. The position of the impact point 9 of the last fuel injected remains the same for all operating conditions so that a rich ignitable mixture is always present in the region of the ignition source 7. The invention is also applicable to an engine operating according to method. In another embodiment the injection nozzle (6), Fig. 2 (not shown) is situated in the marginal region of a cylindrical combustion chamber (4<SP>1</SP>) remote from the piston centre. The combustion chamber is in the cylinder head beneath a valve (10) and the ignition plug (7) is situated in this marginal region opposite to the injection nozzle. In both embodiments the combustion air may swirl about the cylinder axis.

Abstract: 1394719 Valves SOC BOURGUIGNONNE DE MECANIQUE 11 Sept 1972 [5 April 1972] 42088/72 Heading F2V [Also in Division F4] An ignition safety device for a burner or burners comprises a high-tension ignition current generator connected to a spark gap igniter (25), Figs. 1, 2, 7 (not shown), a thermocouple temperature sensor 16 capable of energizing a coil 7 to hold open a fuel gas supply valve 10, 12 having a closing spring 11, and a coil 17 energized through a rectifier to move a stem 19 and thereby move a lever to open valve 10, 12 prior to ignition, the valve being maintained open after ignition by sensor 16 and coil 7. Generator 34 and the rectifier supplying coil 17 are connected to a common mains supply via a common remotely controlled contactor which may be a time delay device automatically switching itself off after the delay and operated manually or under the control of a thermostat, a clock, or a mechanical actuator responsive for example, to the opening of doors of, or the introduction of products into, for example, a cooker. The device may be incorporated into an assembly having two or more burners, the thermocouple 16 being located in the flame of one burner and the spark gap (25) being located near another burner. The illustrated embodiment utilizes two burners (2), 3 to heat a metal radiant panel 1, the thermocouple 16 receiving radiation from the panel 1 and spark gap (25) being located near burner (2), the valve 10, 12 supplying both burners via a manifold 4. To shut off the burners an electrically operated normally-open valve may be located upstream of valve 10, 12 and may be remotely operated by an element having a time-delay allowing time for the burners to be shut-off before the normally-open valve automatically reopens. Alternatively a remotely-operated relay in the lead 15 between each coil 7 and thermocouple 16 may be provided to allow remotely controlled shutoff.

The brush 25 is on a shaft which has Sprockets 30 engaging the chains of the conveyer 12, and is thus driven by the latter. The periphery of the brush moves in the opposite direction to the chains of the conveyer 11 due to the chains being suitably guided by a member 27 (Fig. 4). The brush 25 may be driven in the opposite direction at a higher speed of rotation than that of the chain 11 by the action of a separate drive motor 29. Free wheel drive gearing is provided as necessary at 30 and 31. The brush 25 dips into a reservoir 28 of liquid which inhibits sticking e.g. a soya base oil.
