Title: Improvements in thermionic devices
IPC: H01J1/20
Filed: 1922-08-08
Abstract: 205,613. Robinson, E. Y. Aug. 8, 1922.. Thermionic valve circuits.-A cathode is. formed in two or more parts between which an electron discharge is produced so as to heat the cathode to incandescence. The cathode may be heated at starting by an auxiliary discharge from a filament and the parts may be of flat, semicylindrical or cylindrical shape, or in the form of interlocking helices of wire of rectangular section. The gap between the parts is preferably short. In the arrangement shown in Fig. 2 the two cathode parts 3, 4 are connected through the operating winding 11 of a switch 12 and choke coils 15 with the secondary 14 of a transformer 8. A filament 7 is connected with the secondary of a transformer 9 and is maintained at a negative potential with respect to the cathode by means of a battery 10, so that at starting a thermionic discharge may be produced between the filament and cathode. When a discharge passes between the parts 3, 4 the winding 11 operates the switch 12 to connect the parts 3, 4 across a low-volting tapping 13, and to open the circuit of the filament. A grid may be mounted betwen the cathode and the anode 2. A three-part cathode may be used for three-phase working. In the arrangement shown in Fig. 9 the cathode consists of a cylinder 36 surrounding a tungsten rod 37 swaged to a molybdenum head 40 at each end and connected with leads 38 by one or more thin stems 42 which may be short-circuited by copper leads 42. The rod may be heated to incandescence at starting by passage of current, and during working a discharge is produced between the rod and cylinder. The cathode may consist of two concentric cylinders 3, 4, Fig. 10, between which an alternating potential is applied and the wave may be of a symmetrical shape produced by superposing a continuous potential on an alternating potential; or the outer cylinder may be made positive. An auxiliary filament cathode 7 is mounted on a stem 33. The cathode may be provided with shields as described in Specification 195,691, [Class 39 (i), Electric lamps, Arc &c.], or arranged so as to reduce the discharge at the ends. For this purpose the inner cylinder may be shaped, as shown in Fig. 10, to increase the air gaps at the ends, or may be made shorter than the outer cylinder; or a groove may be formed near each end of the inner cylinder, or both cylinders may be tapered so as to reduce the heating current. ' In the arrangement shown in Fig. 14, the cathode consists of three parallel plates 48, 49, 50. At starting the plates are heated by discharge from V-shaped filaments 51, and during working the outer plates 48, 49 are maintained at a positive potential with respect to the inner plate 50 and the filaments may act as shields to confine the discharge. In a modification, two inner plates are used and the auxiliary filament cathode may be disposed between them.

Title: Pull-down broaching machines
IPC: B23D37/04
Filed: 1938-07-21
Abstract: 517,176. Broaching. HERBERT, Ltd., A., and HUGO, L. J. July 21, 1938, No. 21638. [Class 83 (iii)] A pull-down broaching-machine has an upper tool-holder operable to raise the tool when it is released from the lower holder by hydraulic or other means movable as a whole in unison with the lower holder and having a lost-motion connection with the upper holder which can thus remain stationary while the tool is pulled downwards completely through the work. A main slide preferably actuated by a hydraulic ram carries a rod secured to an upper cross-head 12 connected by parallel rods 13 guided at 15. in the work support, to a lower cross-head 14. The two broaches 18 have tapered neck portions 19 by which they may be detachably secured to a block 20 mounted on the lower cross-head by latches operating as described in Specification 517,175. A cross - piece 25 slidably mounted the rods 13 is bored to receive the upper ends of the broaches, the necks 26 of which may be locked by spring-pressed latches 27. The crosspiece carries a tubular guide 30 which telescopes over a hydraulic cylinder 31 secured to the lower cross-head. The piston-rod 34 carries a collar 35 which may engage under a lifting extension 36 of the part 25. From the loading position, the piston 33 is moved downwards hydraulically or by gravity until the tools have entered and been locked in the lower holder. The rod with the cross-heads are then lowered for the working stroke. As the part 25 nears the work-table, cams 43 pass through holes .44 in the upper holder and disengage the latches 27 after which the broaches are drawn completely through the work. During this latter movement the cylinder 31 .and piston 33 travel downward and the collar 35 leaves the head 36. On the return upward stroke this lost motion between parts 35, 36'is taken up and the upper holder is then raised allowing the upper latches to relock the broaches. On completion of the return stroke of the main slide, cams automatically unlock the latches in the lower holder and fluid is admitted to the underside of piston 33 to raise the broaches to the loading position shown in Fig. 2. The front face of the work-table is machined at 47 to assist in mounting certain kinds of work: In a modification, Fig. 6, the main ram 48, 49 carries a lower pulling-head 50. An upper head 54, slidable on rod 49 has an extension coacting with lifting- collar 58 on a rod having a lost-motion connection 59 with a piston-rod working in a cylinder 61 carried by the lower pulling-head. In the Fig. 6 position, the broach has been released from the upper holder which rests on the work-support and the downward broach movement has been continued through the work. On the upward movement, the lost motion 59 is taken up, the broach gripped by the upper head and the ram 49 fully raised. The cylinder 61 is then actuated to raise the broach, which has been unlocked from the lower holder, to a loading position. For surface broaching the head 54 and broach 63 are removed and a surface broach mounted on the rod 49.
