Title: Improvements in and relating to pattern plates for the production of sand castings
IPC: B22C7/04
Filed: 1940-02-19
Abstract: 534,422. Patterns. LANGLEY ALLOYS, Ltd., and SKRIPT, G. Feb. 19, 1940, No. 3130. [Class 83 (i)] In permanently mounting a pattern on its plate, it is first temporarily secured to the plate by a settable substance, while mechanically located thereon, and is then positively secured, e.g. by screws. Pattern halves of metal are provided with corresponding dowels and sockets and with tapped holes. One half is positioned in a flask, with its section face down, and packed with sand, the flask is inverted and the other half pattern and a second flask are applied. This is then packed, lifted off and inverted. Marking medium, such as oil and and lamp black, is appled to the exposed face of the socketed half-pattern, while still embedded in the sand, and a pattern plate is located-on the flask by the usual lugs &c. thus receiving an imprint which indicates the position of the tapped holes. The plate is removed, holes are drilled at the positions indicated, and the plate re-applied and secured by studs or bolts, passed through these holes into the tapped holes in the pattern, and by type metal or other unshrinkable material poured around these studs or bolts. The plate and pattern are then removed from the flask and positively secured together.. The studs or bolts may then be removed if desired. The half pattern having projecting dowels is treated in the same way except that clearance holes for the dowels are first drilled in the pattern plate at points indicated. by a preliminary application of the plate to the flask &c. marking material having been applied to the dowel ends. In a modification the pattern dowels are spring loaded to recede flush with the surface of the pattern so that clearance holes for the dowels in the pattern plate are unnecessary. If the pattern is of wood, the tapped holes are formed in bushes therein. Pattern plates which have been so used for a number of different patterns successively may be again used for an earlier pattern without resetting if the sets of the locating holes are marked to indicate the corresponding pattern.

Title: Improvements relating to pressurised vapour generators
Inventor: O'NEIL ROBERT
IPC: G21C15/25
Filed: 1965-01-26
Abstract: 1,086,243. Coding reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 19, 1966 [Jan. 26, 1965], No. 3410/65. Heading G6C. In a boiling water nuclear reactor, loss of coolant from the core due to rupture of either water supply or steam outlet pipes is reduced by providing the water pipes with both non- return valves and outlet nozzles opening into the liquid near the free surface and by providing each steam pipe with a constriction to limit the steam outflow. If the liquid coolant level falls due to back flow through the inlets, the nozzles are exposed and the back-flow checked. The steam flow through the constrictions is limited by the sonic flow velocity and normally is approximately adiabatic, the swell pressure drop reducing the vapour wetness. Circulation of the water through the core is effected by the inflow of the coolant through the nozzles which co-operate with upper openings of the coolant channels to function as jet-pumps. The steam generated is collected in the upper section of the pressure vessel and is dried before passing through the outlet constrictions.

Abstract: 417,704. Coking processes. WARNER, A. W., 7, East Washington Street, Media, Pennsylvania, U.S.A. Feb. 2, 1934, No. 3525. Convention date, Feb. 2, 1933. [Class 55 (i).] In the destructive distillation of coal, the charge is fed downwardly through a continuously operated vertical retort which is heated internally by the passage of hot gases, and the escape of the distillates from the inside of an internal cone bounded by the plastic layer is facilitated by maintaining a gas-pervious core at the apex of the cone. This core is formed by introducing coke or the like down the centre portion of the charge. The coal is fed through hoppers 4b, and the coke from a central hopper or tube 6, hot producer gas enters through tuyeres 9, and air with or without steam through tuyeres 11. Coke is discharged through rotating star wheels 3, and steam or a neutral gas may be supplied from a pipe 12. The coke from the tube 6 maintains unsealed the apex of the plastic layer 13 so that the gases from within and outside this layer only meet in the upper and cooler part of the charge before they reach the outlet 5. About 50,000 cubic feet of gas per ton having a temperature of about 1120‹ F. are required, and the coal is preheated in the upper part of the retort before it reaches the hot zone adjacent to the tuyeres 9.

Title: Phonogram carrier, or carrier for corresponding recording of optical, acoustic or similar occurrences or oscillations
IPC: G11B11/08
Filed: 1931-02-04
Abstract: 384,258. Recording sound and other oscillations. ZADDACH, R., 148, Langhansstrasse, Weiszensee, Berlin. Feb. 4, 1931, No. 3564. Convention date, Feb. 18, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] A method of recording sound and other oscillations consists in subjecting a suitable material, other than metal, to electrical polarization so as to influence the polar arrangement of the molecules of the material in accordance with the oscillations. The material is recorded when in a heated or softened state and is afterwards cooled or otherwise treated. Suitable materials consist of one or more of the following : rubber, resins, celluloses, albumens. Alternatively, a metal, metal sulphide or graphite may be dispersed as small particles in a base, or a piezo-electric material such as tourmaline may be dispersed in a wax or like base. The polarizable substance may be disposed on a base in the form of a thread, ribbon, or disc, and such base may consist of metal sheet or foil, cellulose, gelatine or rubber. A metal wire may be provided with a coating of the polarizable substance, or the latter member may be embedded in a silk &c. thread. The recording apparatus shown in Fig. 1 comprises two electrodes 3, between which the ribbon 1 constituting the record carrier is passed, and such electrodes are connected to.an amplifier 6. The ribbon passes to the electrodes 3 from a heating chamber 2 so that the material is in a softened state, and after recording the ribbon passes to a cooling medium 7. The cooling may be effected by liquid air or liquefied carbo-hydrates. When the ribbon is in the form of a coated wire, a single electrode of annular shape is provided. In reproducing, an electrode 11, Fig. 2, cooperating with an electrode 14, is connected. to an amplifier 6 and loud-speaker 12, and a blade 10 is provided in order " to remove the surface layer of absorbed ions." Alternatively, the record ribbon may be used as a continuously varying dielectric medium passing between two electrodes constituting a condenser, or, when the ribbon is of transparent material, optical reproducing means may be used, and a metallic reflecting layer may then be disposed at the back of the ribbon for reflecting back the light beam. The ribbon may be adapted to receive both sound and picture records.
