Title: Process and apparatus for extruding molten steel to produce a cast steel wire and wire thereby produced
IPC: B21C23/00
Filed: 1973-12-28
Abstract: 1460750 Continuous casting MONSANTO CO 28 Dec 1973 [28 Dec 1972] 60086/73 Heading B3F A cast alloyed steel wire of less than 0À035 inch diameter, e.g. containing by weight from 0À3-5À0% Al or from 0À5 to 6À0% Si, or Be, Cr, La, Mg or Ti, has a porosity less than 0À06 volume per cent. This is said to be due to the molten metal having been extruded at a velocity of at least 2400 ft/min. The wire may be used for tyre reinforcement. An oxide film of the alloying constituent, produced by interaction with an ambient atmosphere, stabilizes the extruded melt. A jet 22 of the steel is extruded through an orifice 13 into inert gas, e.g. He or Ar, possibly mixed with an oxidizing gas such as CO or air, which forms the film-forming atmosphere beyond a throated orifice 15. Other film-forming gases which may be suitable for use with the steels are given in Specification 1,153,577. The jet 22 then passes through a converging passageway 18 into more of the film-forming atmosphere in a cavity 21. The inert or mainly inert gas between orificed plates 12, 14 flows from an inlet 23 and attenuates the jet. It flows with the jet 22 into the chamber 19 beneath the plate 14. The plates 12, 14, 17 may be made of high density alumina, beryllia or zirconia. Argon at 100 psig may be used to force the melt 11 through the orifice 13. Together with operation figures, there are given various dimensions and dimension relationships such as angles of orifice divergence, relationship of plate gap to throat diameter and between orifice diameters. The gap between plate 14 and passageway plate 17 may be 0À005-0À020 inch and the throat diameter may be equal to or less than that of the exit of the extrusion orifice 13.

Apparatus for forming billets and thence patterns comprises a heated pump 4 for feeding filtered molten wax from a tank 1 to a cooled extruder 6 which continuously extrudes wax through an outlet tube 12 to a reciprocating take-off mechanism 28 which shears the extruded rod into billet lengths and alternately feeds breeches 18 of the moulds A, B with billets, the latter being subsequently forced into the moulds A, B by respective hydraulic rams 20. The mechanism 28 comprises a pair of tubular billet containers adjustably interconnected by a plate 40 via respective carriers 29, 30 so that each of the tubular containers may be moved along rails 36, 37 by an hydraulic cylinder 41 between a position aligned with the outlet tube 12 and a position within a respective breech 18. Each tubular container comprises an inner tube 31 surrounded by a split sleeve 32 which is thermostatically heated by electrical tapes (33, Fig. 5). To allow acurate alignment of a billet within a breech, each breech comprises a pair of mutually inclined stop-plates 24 arranged within longitudinal slots in a hemi-cylinder and each tubular billet container is pivotally mounted to the respective carriers 29, 30 via blocks 44 and shaft 45 and is urged against an adjustable stop by a spring-loaded plunger 46. A pair of vertical knives (48, 49, Fig. 7) may be provided to trim the ends of a billet en route to a breech 18. The extruder 6 may include a shaft provided with scraper blades and a cooling jacket fed with cold water. The outlet tube 12 may be heated by electrical tapes 13 controlled by a preset temperature sensor 14 to melt the boundary layer of the billet and provide a float for the solid wax core. Each mould A, B may comprise two fixed platens 15, 16 and one hydraulically movable platen 17 and is cooled after injection for 15-120 seconds before ejection of the pattern. Excess wax extruded through the tube 12 and aligned tubular carrier may fall through a steam-heated copper coil into a double walled tank 52 heated by thermostatically controlled oil so that it can be fed back to the tank 1 through a steam jacketed pipe 54 and pump 55.

Filed: 1968-12-19
Abstract: 1,247,547. Electric digital calculators. ALLEN-BRADLEY CO. 19 Dec., 1968 [29 Feb., 1968], No. 60614/68. Heading G4A. [Also in Division G3] A system wherein a machine tool is located at a distance from a central processor includes means at the machine tool for generating and transmitting to the central processor signals, indicative of a part to be machined and operations to be performed in machining, and means at the central processor for receiving the signals, producing signals representing data accumulated from previous operations and up-dating and storing the data signals. As shown, a numerically controlled machine tool control system, as disclosed in Specification 1,159,799, comprises a control processor 10, having a computer memory wherein is stored a plurality of digital machine tool programmes. Each machine shop terminal 14-18 communicates with the central processor, through lines 14B-18B, a desired programme being called up by a punched card inserted in a card reader 14A-18A. This system is modified by providing at the central processor supervisory control and display circuits 20-24 which are used to time the various actions required in the process of machining a part and for keeping count of the parts which are completed or not completed. When machining a part, a card is first inserted in the reader and a four-bit code 0001 transmitted to the central processor followed by an N-bit coded part identification number corresponding to the address in the memory. The N bit code is stored and enables the read-out from the memory into registers of the accumulated information relating to the part, which comprises scrap time, scrap count, abort time, running time elapsed until the operation is aborted, abort count, set-up time, and run-time. The set-up operation is then carried out and the operator inserts a card to transmit a code 0011 to begin the part machinery operation. On completion of a part, or parts, a part completion code 1001 is transmitted and the contents of the registers updated and recorded in the memory. If the part being machined is spoilt the operator scraps the part, and inserts a card to transmit a 0100 scrap code. The runtime register is then cleared and the contents of the scrap time register updated and scrap count increased by one. The system is also employed for determining whether the machine tool is operating at its maximum feedrate by timing the interval between machine tool control system requests for instructions from the central processor which occur at regular intervals dependent on the manual adjustment of the programmed feedrate.

Abstract: 1292960 Transport systems; propelling railway vehicles ASSOCIATED ELECTRICAL INDUSTRIES Ltd 22 Dec 1969 [23 Dec 1968] 61036/68 Headings B7H and B7L A transport system comprises a vehicle having wheels 15, adapted to run on rails 5, and propelled exclusively by an air motor 19, driving one of the wheels, supplied by compressed air from a reservoir 17 carried by the vehicle, there being provided a coupling 51 for replenishing the reservoir at stations in the system. Trays 25 are loaded and unloaded on to the top of the vehicle by means of a carriage 27 mounted on rollers 29 and operated by a pneumatic ram 39. A hook 33 mounted on the carriage is engageable with the trays which move over two lines of rollers 35. A control circuit for operating the vehicle is shown in Fig. 6, wherein when the vehicle stops at a station a bolt 43 is inserted in a floor socket, and coupling 51 connected to a compressed air supply. Air is then supplied to the reservoir and to a cylinder 71 directly from the coupling and via a valve 77 from the reservoir which cuts off valve 73 thereby rendering the air motor inoperative. A control lever 41 can now be operated to supply air to ram 39 via regulator 63 to move the carriage to collect a tray 25. Reversal of lever 41 supplies air to the opposite end of the ram via regulator 79 to move the carriage back, thus loading the tray on to the vehicle. When the carriage is back in place valve 77 is shut, stopping the supply of air from the reservoir to cylinder 71. The coupling 51 is then released so that the other air supply to cylinder 71 is stopped thus enabling the valve 73 to pass air to the motor 19 for movement of the vehicle to the next station. The mechanism 23 associated with hook 33 may be rotatable through 360 degrees, thus enabling carriage 27 to be used to load trays 25 from both sides of the vehicle. (For Figures see next page.)

Disks 30 prevent. the leaves being wedged between the wheels 12 and allow them to be removed onto a conveyor comprising an endless belt of tines 32, adjusted from the ground by a threaded rod 43. The belt raises the leaves into transverse parallel screw augers 44, 45 which transfer the leaves into the central part of the machine where they are taken up by a first central longitudinal conveyor 60 composed of spaced bars. The conveyor 60 transfers material onto a second conveyor 74 of the same type which discharges the leaves into the rear collecting container 84 which may be emptied automatically by operation of a hydraulic cylinder 88 or a mechanical lever, not shown pivoting the rear part of the container about the lateral axis of a pivot pin. The beets are lifted by vertically adjustable shares 89 and/or pairs of inclined disks (not shown) onto one of a pair of rotating disk conveyors 93 which may be frusto-conically shaped and are composed of rods. The beets are prevented from being spun off the disk conveyors 93 by guide rails (101) Fig. 4C (not shown) as they are carried to either side of the machine where they are picked up by bars on vertical elevators 102 from the top of which they are transferred to a container 114. A rotating spoked wheel (138) Fig. 9 (not shown) may assist the transfer of beets onto the disk (135) and a similar wheel (142) may assist the transfer of beets from the disk (135) to the vertical elevator 102. The beet container 114 may be tilted by a hydraulic ram (115), Fig. 5 (not shown) about a pivot (116) to empty the beets or unloading conveyor chains (119, 120) Figs. 2B, 5 (not shown) may be used. The belts and conveyors may be operated by individual hydraulic motors driven by a master pump (141) Fig. 7 (not shown) or may be operated by conventional chains or grooved belts and gears from an engine drive shaft.

Title: Improvements in or relating to dynamic semiconductor storage elements
IPC: G11C11/35
Filed: 1978-09-15
Abstract: A dynamic semiconductor storage element comprises an MOS-storage capacitor (1,3,4) arranged on a semiconductor layer (4) of one conductivity type. This capacitor is fed with the charge to be stored via a bit line (5) constituted by a strip-shaped buried layer of the opposite conductivity type. A portion of the word line (1) forms a conductor path which is arranged above and insulated from the semiconductor layer (4) and serves as the outer electrode of the storage capacitor. In storage elements of this type, the drive voltage range on the word line is kept low by increasing the doping of the semiconductor layer (4) from its surface with the insulating layer (3) to a depth of a few 100 nm. The invention is particularly suitable for highly integrated storage components. <IMAGE>
