Title: Improvements relating to electromagnetically-operated mercury switches
IPC: H01H29/18
Filed: 1935-02-01
Abstract: 453,229. Mercury switches. CIANCHI, A., 72, Greencroft Gardens, Hampstead, London. Feb. 1, 1935, No. 3399. [Class 38 (v)] An electromagnetic ally operated mer cury switch comprises a sealed container 1 having electrodes 5 6 projecting into the main part and ar electrode 7 projecting into a pocket in a side limb. Floating on mercury 3 is ar iron armature 2 pro vided with a small hole 8 in its base. Surrounding the electrode 5 is an insulating cup 20 supported by limbs 21 and provided with a small hole 22 at the bottom. The switch is surrounded by a solenoid 4 and when this is de-energized the parts are in the position shown, and electrode 6 is in electrical connection with electrode 5 but is disconnected from electrode 7. When the solenoid is energized, the armature 2 is drawn down rapidly thus displacing the mercury to cause connection with electrode 7. The mercury inside the armature is drawn down to break connection with electrode 5. This break is delayed by the mercury flowing through hole 22 in cup 20. Mercury gradually flows through hole 8 in the armature and the original position of the mercury is restored. This may be prevented by the flat top 9 of electrode 6 covering the holes when the armature is depressed. The switch may be arranged for continuous self interruption. In a modification a ball valve is arranged to close the passage in the armature while it is depressed, and the switch may be mounted on a wall so as to be rotatable to vary the time delay effect on the side limb contact 7.

Filed: 1941-03-14
Abstract: 547,952. Billet-piercing. WELLMAN SEAVER ROLLING MILL CO., Ltd., McLAY, G. S., WILLIAMSON, J C., and MARNIE, J. March 14, 1941, No. 3527. [Class 83 (iv)] A press for billet-piercing has one or more punches 13, 13a, Fig. 4, mounted in a slide 71, movable in guides 72 of the frame 2 to bring a punch into rough alignment with the axis of the billet container 7, a bolt 78 which can be moved axially into a recess 76, Fig. 5, in the base of this punch to align and lock it and means, such as hydraulic rams 12, Fig. 1, to raise the container 7 till it engages a guide ring 56, as described in Specification 547,951 and forces the billet therein over the punch. During the rise of the container, fluid in return cylinders 15 is forced into an accumulator and a cam 41 engages a lever 43 which, acting through linkwork 45, 48, 50, moves a perforated slide 52 so that it obstructs the ejector 25 to push the hollow billet out of the container 7 on the return stroke. The slide 71 may be moved by an electric motor controlled by a limit switch and the bolt 78 by a hydraulic piston 79 which may have an extension 88 to operate a switch 87, when the bolt enters the recess 76, which releases the fluid control valve of the main cylinder 10. The punches not in line with the container may be in a cooling device and the container may be cooled by water which with any scale escapes by a hole 27 and is caught by a tray 28.

Patent GB-786728-A (GB)
Title: Method and apparatus for making hollow blades for compressors and gas turbines
IPC: B21D53/78
Filed: 1956-07-13
Abstract: 786,728. Making turbine and compressor blades; stamping. STALKER, E. A., and CLARKE, D. J. July 13, 1956, No. 3590/57. Divided out of 786,727. Classes 83 (2) and 83 (4). A method of fabricating the deflection surfaces of a fluid deflecting blade, e.g. a turbine or compressor blade, comprises forming a metal sheet between dies while applying a chordwise stretch to the metal so controlled by relative slipping between dies and metal that the metal is substantially free of internal stress for brazing purposes. The upper deflection surface 1 of the blade is formed by placing the sheet metal across the recess 8 of a die 9 (Fig. 3) and held by gripping members 40 and 35 which allow a controlled slip whilst the male die 10 is forming the blade contour. The lower deflecting surface 2 is similarly formed by placing a metal sheet over a female die 11 and stretching it to shape by a male die 12 (Fig. 4). To produce the complete blade the two surfaces are juxtaposed and held assembled by spot welds at nose and tail during brazing. After the braze material has been melted in a furnace, the blade is trimmed off. Each blade part is produced from separate lengths or from a continuous strip of sheet metal 30 (Fig. 2) fed over a table 34 by feed rollers 31, 32 to the dies 9 or 11. A stop 39 limits the feed of the sheet. The male die is carried by an hydraulic plunger in a cylinder 42 and the clamp 35 is operated by an hydraulic plunger 48. The other clamp 40 is pivoted at 54 and actuated by an hydraulic plunger 56. Hydraulic pressure is supplied from a pump 60. The press is controlled by a reversing valve 70 actuated by the feed roller 31. When the sheet has been fed up to the stop the roller 31 actuates valve 70 to supply pressure fluid to the die and clamp cylinders 42 and 49 respectively. The clamp 35 grips the sheet before the die 10 or 12 presses the sheet into the die recess. After a predetermined movement of the male die an arm 76 on the die operates a valve 77 to supply pressure fluid to the clamp 40. Thus, both clamps are engaged and the holding force is controlled to provide for a predetermined amount of slipping. Finally, the formed blade part is cut from the sheet.

Title: Improvements in or relating to typewriting and record-card punching machines
IPC: B41J3/50
Filed: 1946-02-06
Abstract: 626,456. Punching-machines. BRITISH TABULATING MACHINE CO., Ltd. Feb. 6, 1946, No. 3727. Convention date, Feb. 15, 1945. [Class 31 (ii)] [Also in Group XVI] In apparatus as described in Specification 562,278, adapted to type by power-driven means on a sheet moved by a carriage and to punch by power-driven means a card moved by a carriage and including a set of digit keys having variable connections to the typing and punching apparatus, whereby depression of a key may cause a digit to be either typed or punched or both typed and punched, means are provided by which more than one sequence of operations or programme can be set up and the particular programme can be selected at will. The arrangement can be employed when more data has to be punched than can be accommodated on a single standard card and two or more cards are necessary in which the fields upon which the matter is to be punched vary. In the present example, three cards 1, 2 and 3 are successively punched, some or all the matter recorded on card 1 being printed on two lines of the sheet, and the matter recorded on cards 2, 3 being printed on the two succeeding lines of the sheet. For this purpose, relays RA, RB, RC are included in the key circuits of the relays operating the punches corresponding to digits 1, 2, 3 respectively. To commence operations, card 1 is punched on column one by depressing digit key 1 to designate the type of card, the machine being set so that no printing on the sheet takes place. At the same time, relay RA is energized to close contacts RA1 so that through margin contacts R5A the pick-up winding of a relay RD is energized. Contacts RD1 now close to complete the holding circuit of the relay RD. Similarly, when cards 2 and 3 follow on, the punch keys corresponding to digits 2, 3 are operated to punch their first columns, and relays RE and RF respectively are energized. The relays RD, RE, RF control the closing of contacts in series with relays R10-1 to R10-13 which cause through suitable plug connections operations such as zero elimination, tabulation, &c. to take place at certain column positions, as described in the Specification referred to. Thus, the punching of card 1 in column one with the digit 1 causes relay RD to be energized and contacts RD2, RD3 in series with R10-1 and R10-2 to be closed and thus determines the scheme of the punching carried out on the card and the manner in which the corresponding printing on the sheet is effected. Similarly, for card 2, relay RE closes contacts RE2-RE6 and for card 3, relay RF closes contacts RF2-RF5. If certain columns in one card, e.g. card 1 are to be punched and the same columns of cards 2, 3 are not punched, no contacts need be placed in the circuits of the relays plugged to such columns, as is shown for relays R10-3 .... R10-6. Each relay RD, RE, RF remains energized throughout the period the corresponding card is passing through the punching apparatus.
