Title: Improvements relating to the manufacture of incandescent electric lamps
IPC: H01K3/10
Filed: 1926-04-12
Abstract: 251,259. Westinghouse Lamp Co., (Assignees of Higgins, J. J.). April 23, 1925, [Convention date]. Making lamps; filaments, supports for.-In a machine for making mounts, the hooks or pigtails are first inserted in the arbors and the filament supports thus formed are transferred to mechanism for completing the mounts. The machine described is designed to make mounts of the kind shown in Fig. 4. The filament supports are formed on an intermittently rotated frame 52 having a number of intermittently rotatable arbor holders. At the position a, glass rods are fed into the tubular holders 68 and are positioned by a gauge 84, and jaws 61 are then closed to grip the rods by conical members 75 being forced by springs 76 between the upper ends of the gripper arms, which are pivoted at 64 in rotatable toothed discs 57 gearing with a central toothed wheel 58 serving to rotate them intermittently. The members 75 are mounted in pivoted carriers 72 having projecting arms 78, which are lifted to open the grippers 61 by a fixed cam track 79 at the loading position and by a cam-actuated lever 224 at the discharge position d. At the position b the ends of the glass rods are softened by burners 86 and a plunger 87 rises to form the buttons into which the hooks are inserted. These are formed and inserted at position c by known devices comprising a ram 89 and wire cutting and coiling mechanism 95. If it is desired to form pendant hooks 10, Fig. 4, a member 106 is operated by a cam 108 to bend them down after insertion. The finished filament supports are transferred at position d from the frame 52 to a stem head 152 on the stem-making machine C, by means of grippers 226 mounted on an arm 228 adapted to swing horizontally about a post 229 and also to slide on it vertically to enable the glass rods to be withdrawn from the clamps. The grippers 226 are actuated by a slide 231 operable in the two extreme positions of the swinging arm 228 by levers duplicated on a bracket 258. The stem heads comprise a number of grippers pivoted on vertical rods 157, 158, Fig. 10, the exhaust tubes 5 being held by grippers 172, 173, the flare tube 6 by grippers 168, and the filament support 7 by grippers 163. Shields 150 protect the leading-in wires. The grippers 172, 173 are operated by turning the rod 158 by a handle 161, thus operating links 177, 178. Fig. 11, connected to the grippers. A handle 159 on the rod 157 similarly enables the grippers 168 to be operated. The grippers 163 are operated automatically by a cam 192, a link 191, a crank 185, and pinions 182 engaging rack teeth on the jaws of the grippers. The stem parts are assembled at the positions G, H, Fig. 2, softened at position I, the pinch is formed by tongs 199, 201 at position J, compressed air is passed into the exhaust tube by a pipe 204 at position K, to blow the exhaust aperture 11<1> through the pinch, the mount may be annealed at position L, and is discharged at position M to an operator at 200 who applies the filament to the hooks.

Title: Improvements relating to drying apparatus of the festoon conveyor type
IPC: D21F5/00
Filed: 1932-04-04
Abstract: 380,010. Drying fabrics in long lengths. WIGGINS, TEAPE, & CO. (1919), Ltd., 10, Aldgate, and ROUGH, W. M., 119, Westmount Road, Eltham, both in London. April 4, 1932, No. 9644. [Class 34 (i).] In machines for conveying continuous webs of paper or other fabric in festoons through drying chambers, of the kind comprising a series of chain conveyers A .. E arranged in succession along a U-shaped track, and wherein the web R coming, for example, from a coating machine F is hung in festoons from rods P deposited at intervals along the conveyer chains at one end of the track, and is removed at the other end for delivery to a reeling machine G, all the conveyer sections are driven, through the intermediary of worm gearing and cross shafts I, J, K from a common rotary shaft H extending longitudinally of the machine. The shaft H may be driven through bevel gearing L, a crossshaft L<1>, and a pulley L2, from the same overhead shaft as drives the reeling machine G and coating machine F. The conveyers comprise along the straight portion of the track parallel trackways M, N, on which endless chains carrying the rods P move. The chain 7 of the conveyer section A passed downwardly around a guide pulley coaxial with the pulley 12, shown in Fig. 8, and engages with a chain wheel 1 which is driven from the shaft J through gearing comprising chain sprockets 2, 3, an endless chain 4, and spur wheels 5, 6. The chain 7 returns to the fore end of the section A over fixed pulley wheels 9, 10 and an intermediate weight-loaded jockey pulley S. The pulley 12 carries the non-driven end of the chain 13 in the next conveyer section B. The gearing arrangements through which the successive sections are driven from their respective cross shafts are so chosen that the speed of travel of the corresponding chains is successively less, the sticks P becoming more closely spaced as the web moves through the machine. The motion of the web is reversed at a turntable C<1> comprising an outer series of spaced pulleys 26 guiding a chain 25, and an inner series of spaced pulleys 34 guiding a chain 33. The chain 25 is the same as that traversing the outer trackway of the adjacent conveyer section C. The chain 33 for the inner edge of the arcuate track is driven at a suitably reduced speed through appropriate gearing from a chain wheel driven by the chain 27 which traverses the inner edges of the adjacent straight portions of the section C. The guide pulleys 26, 34 are arranged slightly inclined to the horizontal, so as to prevent contact between the sticks and the backwardly moving parts of the pulleys.

Title: Automatic electric circuit breakers
IPC: H01H71/68
Filed: 1960-03-21
Abstract: 884,450. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION. March 21, 1960 [March 25, 1959], No. 9847/60. Class 38 (5). An automatic circuit-breaker has primary and auxiliary trip means, the latter being operable by resetting movement of the closing mechanism when the primary trip is not reset. The circuit-breaker comprises two contact sets each having a resiliently-mounted main fixed contact 19 and an arcing contact 26, these contacts co-operating with movable contacts 23, 28 mounted respectively on channel-shaped arms 24, 29 which are pivoted at 25, separated by a spring 30, and urged anti-clockwise by a spring 33 acting on a pin 38 carried by ends 39 of the arm 24 and slidable in the bifurcated end 40 of a guide 34. The arms 24, 29 are also pivoted at 42 to an insulating- toggle link 41 whose shaft 44 slides in slots 45 of a fixed channel-shaped cam 46 between a lower deadcentre position and an upper position corresponding to closed and open positions respectively. The primary trip comprises an arm 71 pivoted at 67 in the cam 46, urged clockwise by a spring 68, and normally latched by a catch arm 52, the extension arm 72 of the arm 71 engaging the shaft 44 in this position to prevent undesired contact opening due to external shock. The catch arm 52 is pivoted on one end of a shaft 55 and is urged upwardly by a spring 59, the other end of the shaft 55 carrying a similar spring-controlled arm 64 having a contact 62 normally engaging a fixed contact 61, Fig. 4. The arms 52, 64 engage the flange 60 of a plunger 49 controlled by a coil 57 which may be energized by closure of a bimetallic device external to the breaker, Fig. 5 (not shown). The closing mechanism comprises a plunger 75 having steel push plates 76, 77 and controlled by a coil 73 connected in series with a manually-operable switch and the contacts 61, 62, Fig. 5 (not shown), energization of the coil 73 producing downward movement of the plunger 75 which is reset by springs 84, 85 whose ends engage brackets 88, 89 carried by plates 77, 76 and studs 86, 87 mounted on the breaker housing 13. Plates 76, 77 also carry a roller 82 engageable with the arm 72 and a pin 95 on which pivot the ends 93, 94 of a link 92 forming the auxiliary trip means, this link being urged anti-clockwise by a spring 96 to normally engage a rivet 98 on the arm 72. To trip the breaker, the coil 57 is energized to depress the arms 52, 64, movement of the arm 52 releasing the arm 71 which rotates to knock the shaft 44 from the dead-centre position and allow the springs 33 to open the contacts, Fig. 3 (not shown). To reclose, the coil 73 is energized to operate the plunger 75 whose plates 76, 77 depress the shaft 44 and whose roller 82 engages the arm 72 to relatch the arm 71. Should the breaker reclose on to an overload the arm 71 will not relatch and, together with the arm 72, rotates slowly clockwise when the plunger 75 resets, thus allowing the end 97 of the link 92 to engage the shaft 44 near the end of the plunger stroke and so trip the breaker.

Filed: 1967-03-02
Abstract: 1,179,785. Gas turbine power plant. GENERAL ELECTRIC CO. March 2, 1967 [July 11, 1966], No.9894/67. Headings F1G and F1Q. A gas turbine powerplant comprises primary and secondary gas turbine units each including a compressor, a combustion chamber and a gas turbine, and power transmission means operable in a first mode to connect the primary unit to a power output shaft, the secondary unit remaining inoperative, and in a second mode to connect the primary unit to drive the compressor of the secondary unit and the secondary unit to drive the power output shaft. The primary gas turbine unit 11 comprises an axial-flow compressor 17, combustion chamber 18, turbine 19 driving the compressor 17, and a separate power turbine 21, the exhaust gases from which pass through a fixed or rotary regenerator 23 to pre-heat the combustion air. The turbine 21 drives a shaft 22 which extends into a transmission casing 13. A secondary gas turbine unit 12 comprises a centrifugal compressor 30 mounted on a shaft 33 extending into the casing 13, a combustion chamber 31 and an inward flow turbine 32 mounted on a shaft 34 also extending into the casing 13. Sliding clutch members 54a, 54b are provided such that during normal running member 54a connects primary power turbine shaft 22 with a gear 43 mounted about the shaft to thus drive the final power output shaft 40 through gear 42 and gearbox 14. During such running the secondary turbine unit 12 is not operating and gear 44 is running free on shaft 34. When power exceeding the maximum output of primary unit 11 is required, the secondary unit 12 is started by moving clutch member 54a to the right so that shaft 22 drives the secondary compressor 30 through shaft 33 but is disengaged from gear 43. Simultaneously, clutch member 54b is moved to the left to connect the secondary turbine 32 with gear 44 so as to drive the output shaft 40. The maximum power output of turbine 32 is substantially greater than that of turbine 21. The exhaust gases of turbine 32 may pass to the regenerator 23 which may also pre-heat the air for the secondary combustion chamber 31. The plant is more efficient at part load than a plant of comparable output having a single power turbine.
