Title: Improvements in or relating to devices for straightening the leading-in wires of electric incandescent lamps and the like
IPC: H01J9/28
Filed: 1931-06-16
Abstract: 377,382. Electric incandescent lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. June 16, 1931, No. 17463. Convention date, June 26, 1930. [Class 39 (ii).] In a method of directing and straightening leading-in wires secured to electric lamps or discharge tubes, the wire is led over two relatively movable points of support between which it is straightened during such movement. The leading-in wires 11, Fig. 6, from the lamp or discharge tube 10 are brought over a stationary member or support 9 adjacent thereto and are gripped lightly by pivoted members 1 which are then retracted in a horizontal direction to impart upon the wire a light pull which is augmented towards the end of the movement, the additional pull serving to overcome, the tendency of the wires to spring back when released. The wires 11, which emerge from the lamp bulb 10 in an arbitrary manner, as indicated in dotted lines in Fig. 6, are engaged by the grippers 1 which, at this stage, act as wire-seekers and rotate in a clockwise direction through an angle to bring the wires 11 against stops 2, Figs. 4 and 6, consisting of plates mounted upon a sleeve 24 which is carried upon a sleeve 8. The wires are pushed into grooves at the end of the sleeve 8 and held therein by the grippers 1 while the sleeves 8, 20 are moved axially by a fork 21 engaging a bush 18 surrounding them. During this movement through a distance S the ends of the angle-levers 1 bear upon plungers 3 and move them inwardly against the pressure of light helical springs 13 surrounding their inner ends within a housing 4. This movement continues until a collar 12 secured on each of the plungers 3 bears upon the end of a body 14 which is restrained by a helical spring 15, whereupon the levers 1 are caused to swing and an increased pull is transmitted to the wires 11 just before they are released.

Surface treatment with liquid materials; pneumatic collectors.-Relates to vehicles for distributing dust-laying oils, tar, or tar products on road surfaces, and consists in providing fluid-pressure-operated valves for controlling the flow of oil or tar through separate pipes leading to the distributing nozzles, and means, controlled by the speed of the vehicle, for supplying pressure fluid to the valves. The vehicle shown in plan in Fig. 3 carries a pipe 10 connected with an oil tank wagon. The oil passes through a heater 19 to a box 11 fitted with valves 12 which control the supply along pipes 13 to oil-spraying devices 22. Air under pressure, derived from a compressor 6 driven by the propelling motor 5, is delivered through a heater 14, and the hot air is utilized through pipes 21 to give an ejector action at the spraying- nozzles, and through a pipe 16, tank 7, governor-controlled valves 43, and pipes 35 to actuate pneumatically the oil-supply valves 12 in accordance with the speed of the vehicle. The valve 12, as shown in detail in Fig..9, comprises a sliding member .24 normally pressed downwards by an adjustable spring 31 so as to close the supply pipe 23. The valve is opened by air under pressure acting through the pipe 35 on a piston 30, the air exhausting through a passage 34. Figs. 6 and 7 show a spraying-nozzle which is supplied with air through a pipe 57 connected to one of the pipes 21, Fig. 3, the space outside the pipe 57 being supplied with oil which is sprayed through a slit 49 by an air jet acting through a slit 55. The pipe 57 is adjustable within the fixed casing 56 and is centred by projections 55'. A fan 9, Fig. 3, driven from the motor 5, serves to raise dust from the road surface in front of the spray through a flexible nozzle (not shown) and the dust so raised is delivered over the oiled road surface by a nozzle 63.

Abstract: 925,542. Discharge lamps. BURROUGHS CORPORATION. May 22, 1959 [May 22, 1958], No. 17573/59. Class 39 (1). [Also in Group XXXVIII] An indicator tube has an envelope 12, filled with a gas such as neon at about 40-120 mms. pressure, and a plurality of glow cathodes 22, in the form of numbers, letters, &c. arranged in a group or groups of two sets with one of a pair of anodes 36, 40 respectively associated with each set, each of the anodes being interposed between its associated set of cathodes and the other anode whereby each of the anodes shields its associated set of cathodes from the other anode. A shield 38 can be mounted between the anodes 36 and 40 to further shield each of said sets of cathodes from the other anode. All the electrodes and the shield 38 are mounted in stacked relationship. Each cathode in one of the sets, e.g. representing the odd integers, is connected electrically to a respective cathode in the other of the sets, e.g. representing the even integers. The interconnections can be made by connecting each cathode to a pin 16 and connecting the appropriate pins together inside or outside the envelope, or leads from each two cathodes to be connected together can be secured directly to the same pin inside the envelope, or the socket to be used with the tube can be wired to provide the desired cathode pairs. A screen 42 is provided to prevent sublimation of metal from the cathodes on to the plane or curved viewing window 20. The cathodes 22 can be made from stainless steel, aluminium, nickelchromium alloys, or molybdenum by etching, stamping or formed wire and are displaced laterally with respect to each other. Each anode 36, 40 is formed of wire mesh and all the electrodes are provided with apertured tabs for mounting between insulating spacers 34 on elongated pins. The shield 38 can be at a neutral potential relative to the cathodes and anodes. A cup-shaped member 24 as described in Specification 879,033, of imperforate or mesh conductive or non-conductive material rests on a mica disc 30, and surrounds the electrodes. The cup 24 can be at a neutral potential or can be connected to the shield 38. The screen 42 can be connected to the shield 38. A binarytype decade-counter in which the tube is used is shown in Fig. 3, and includes four flip-flop circuits 50, 52, 54, 56, input pulses being fed into the first circuit 50, the output of which is connected both to the counting chain and to the anodes 36 and 40. The output lines of the circuits 52, 54 and 56 are fed into a resistor matrix 58 and the output of the matrix is applied to a particular cathode pair. In the construction shown in Fig. 4, the tube 10<SP>1</SP> comprises one group 60 of two sets of electrodes and a second group 62 which includes cathodes, anodes 36<SP>1</SP> and 401 and a shield 38<SP>1</SP>. The tube 10<SP>1</SP> can be operated so that one cathode in each group glows at the same time to achieve a two-numeral read-out.

Title: An improved machine for slotting and like purposes
IPC: B23C3/30
Filed: 1920-06-28
Abstract: 162,574. Gourriet, F. V. June 28, 1920. Milling-machines. - A machine particularly designed for slotting the head and stems of poppet valves holds the work in or on a sliding plunger fed by a spring against a cutter mounted in a frame that can be swung aside to facilitate loading the work-holding fixture. For cutting the collar slot in the stem, the valve is held in a V-block 44, located on the head of the plunger 6 by dowels, by a spring-controlled V -block 48 against an adjustable end .stop 52. The plunger is guided by pins 7 engaging slots in the body 4 adjustable in a base 1 that may be secured to a bench. A cam ring 31 is rotatable by hand on the body to bring raised flats 32 under the pins 11 on which the cutter-frame 12 is trunnioned, thus maintaining the plunger depressed in opposition to a feeding-spring 9. A stop 34 on the cam determines this position. The cutter-spindle is mounted in bearings 13 in the frame 12 braced by a bridge 17 carrying adjustable screws 18 that take the cutting thrust close up to the cutter 15. With the swing frame in the operative position slots 22 engage pins 23 and a stirrup 24 is passed between a hasp 28 and the body for locking by a nut 30 on a pin 26 passing through a slot in the hasp. When the frame is secured in this position the cam is operated to allow the spring to feed the work-carrying plunger to the cutter that is rotated by a hand-crank 16 or by power. After cutting into the stem from one side the work is indexed 180‹ by a plunger 55 with bevelled ends resting on spring-pressed balls 38 in a bore in the plunger and snapping into the slot just milled. A finger-piece 57 enables this action to be felt. For slotting the head of the valve, the fixture 44 is removed and the valve is centred by the balls 38 and by the conical surface 41 under the head. Milling-cutters. - The cutter arbor is integral with the cutter and is reduced in diameter in proximity thereto in order to obtain maximum penetration with a small diameter. In a modification, the cutter is integral with the reduced diameter portion only, the end portions 14, Fig.. 11, being screwed on.
