Abstract: 1334126 Electron beam apparatus; electrode processing BALZERS PATENTUND BETEILIGUNGS-AG 22 July 1971 [12 Aug 1970] 34336/71 Heading H1D A method of vaporizing and/or working materials uses a device with thermionic cathode 4 and auxiliary electrode 5 wherein the latter is at a positive potential relative to the cathode before vaporizing and/or working whereby electron bombardment heats the auxiliary electrode to above 600‹ C. (e.g. # 1000‹ C.) to effect degassing, the released gas is pumped away, electrode 5 is switched to a high negative potential relative to the cathode, e.g. by switch 15, Fig. 2 (not shown), and the vaporizing and/or working performed after further pumping down, to pressures of 10<SP>-8</SP> ton and less for example. The material is in copper crucible 2 carried by cooling water supply lines 3, while thermionic annular cathode 4 is surrounded by the hollow, ring-shaped auxiliary electrode 5 with a slit for electron emission, the latter connected to tubular H.T. supply 6 containing also the return line for the cathode heating current. The procedure enables cooling of the auxiliary electrode to reduce degassing to be dispensed with. Fig. 1 includes assembly flange 7 adjacent insulator 8 and crucible 2 may be earthed while cathode 4 and electrode 5 are at the high negative potential (e.g. a few thousand volts). Vapor deposition of thin film electronic circuits is mentioned.

Title: Improved method of and means for use in the manufacture of pipes, conduits, and other like hollow objects of plastic material
IPC: B28B21/24
Filed: 1932-12-12
Abstract: 411,852. Moulding pipes, tubes, &c. PORTER, W. A., O'Connell Street, Red Hill, and DAVIS, A. T., Prospect Terrace, Kelvin Grove, both in Brisbane, Australia. Dec. 12, 1932, No. 35200. [Class 87 (ii).] Concrete pipes and the like are manufactured by pouring plastic material into the annular space between a core and the mould, simultaneously vibrating the mould, and also moving it either axially or rotatably relatively to the core. In one construction the material is placed in a mould provided with rotating and/or axially-moving cores which is mounted on a vibrating table and is tamped by annular tampers while still being vibrated. After the vibration and tamping actions have ceased, the rotating core is withdrawn gradually. The moulds are then removed from the table and the pipes taken out. The moulds B are fixed on the platform A by the coned heads B<3> on a crosshead B<3> raised and lowered by the pedal C<2>. and are vibrated by the ratchet wheels A<2> driven from the shaft A<4>. The cores F<3> are rotated by gearing F mounted on the crosshead F which is raised and lowered by chains G driven from the counter-shaft H controlled by a hand-operated band-brake H<3>. The cores can yield relatively to the crosshead F so that the vibrations of the mould are not transmitted to the gearing F<1>. The moulds may be rotated by spur-gear in the same direction as, or oppositely to, the core, but usually are non- rotatable. The annular tampers L<1> are carried by a crosshead L raised and lowered by a pedal M or by power-gear. The cores are usually rotatable when making circular objects such as pipes but are only movable axially when making columns with polygonal holes therethrough. As modifications, the moulds may be fixed to the crosshead B<5> and raised with it, or hinged so as to swing round one of the guide posts D for removal from the machine ; while the cores may have a knuckle-joint connection with the crosshead F and may be vibrated by crank-mechanism acting on their lower ends independently of the jigging-mechanism for the mould table. Also the crosshead F may be raised and lowered on screwed portions of the guides D.

Title: Improvements in record card controlled accountancy machines, known as summary-punching machines
IPC: A21C11/18
Filed: 1953-12-18
Abstract: 740,180. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 18, 1953 [Dec. 23, 1952], No. 35284/53. Class 106 (1). An installation comprises in combination a single summary punch and at least two record card controlled calculating machines, each machine having link relay circuits adapted to operate so that results registered in the accumulators of respective machines may be punched automatically in a summary caid by the single summary punch in the same order as received from the machines or in a predetermined order if the results are received from the machines simultaneously. Referring to Fig. 2 a hopper 1 supplies cards which are sensed by brushes 2 which control punches 3 and then by brushes 4 which verify agreement with the data duplicated by the punches and sensed by brushes 5. After sensing by brushes 4 the cards are ejected into stacker 8. A series of levers L4, L5, L6, are provided to detect the presence of cards in the hopper and under brushes 2 and 4, respectively, operate contacts, not shown, which control various machine functions in known manner. Hopper 6 is employed to feed blank cards under punches 3 and then under comparing brushes 5 before being ejected into stacker 7. Another series of levers L1, L2, L3 control through their contacts to punching circuits shown in Fig. 3. Referring to Fig. 3 the start key 9 completes a circuit energizing relay 10 which establishes its own hold circuit through contacts 10a, and actuates the clutch magnet in the usual manner Levers L1, L2, L3 energize control relays 13, 11, 40 respectively. Referring to Fig. 4 a double switch 14 is shown which places the operation of start relay 15 of the first accounting machine under control either of the normal circuits, not shown, which lead to terminals N, or the circuits of the summary punch which lead to terminals P. When switch 14 is in the latter position a circuit is completed between lines 16 and 17 through switch 14, wire A1, contact 28a, Fig. 3, wire A2, switch 14 and relay 15. The pick-up of relay 15 starts the first accounting-machine. Data to be punched is registered in an accumulator shown diagrammatically as a common contact 20 and a series of ten contacts 21. A brush 22 gives the value of the result contained in the accumulator. When the control for punching a result is initiated by one of the accounting machines a series of control circuits momentarily stops the record machine when the latter is ready to initiate punching of its own results. When this occurs simultaneously for both accounting machines the punching from accumulators of the first machine is arranged to take place first. In order to differentiate the punched cards from one accounting machine from those of the other machine, a contact 18d is provided which when associated with emitter 36 punches a sign characteristic of the accounting machine giving the results.
