Apparatus shown for cooling the gases comprises jacketed-tube heat exchangers wherein the gases from reaction tubes 3 flow through heat exchange tubes 5 and the molten metal passes through the jackets 6 in a contraflow direction to that of the gas in tubes 5. The molten metal flows from the heat exchange tubes 5 via a conduit 12 to a tank 13 in which it is cooled by a heat exchanger 14 in which water circulates to be converted into steam removed at 19 to a point of use. After cooling in the tank 13, the molten metal returns through a conduit 20 to the heat exchangers. Circulation of the molten metal through the heat exchangers is assisted by using a pump 21 to circulate an inert gas such as nitrogen in a circuit comprising the tank 13, a conduit 22 and the conduit 12.

Erase, write and monitor heads 8, 9, 11 are provided for each track, and each monitor head 11 normally checks recording by indicating a fault when no data is detected in the selected track for a period of five seconds. The areas 53-55 have a predetermined length (<SP>1</SP>/ 3  sec.) and spacing (1 sec.) and extend the full width of the tape, and are recognised from the output of all the monitor heads 11 by logic circuitry 57; the areas are thus distinguished from recording faults.

Title: Fusion coated metal base and method of producing same
IPC: C23C24/10
Filed: 1961-11-20
Abstract: A metal base is fusion-coated with a nickel-chromium alloy containing residual phosphorus by applying to said base a powdered alloy of nickel, chromium and phosphorus in an amount to provide from at least about 1 to about 4 gms. of said fused alloy per sq. foot of fused coated surface, and thereafter heating the base in a protective non-oxidizing atmosphere at a temperature and for a time sufficient to melt the powdered alloy and thereby provide a continuous fusion coating of said alloy on the surface of said base, said atmosphere having a dew point not greater than about -5 DEG  F. maximum and preferably not greater than about -10 DEG  F.  The metal base is a ferrous metal base having, or subsequently heat-treated to have, sufficient ductility and formability for fabricating purposes and in the preferred continuous process usually low carbon, cold-rolled steel strip of about 0.03-0.2% carbon content: alternatively, said base is a non-ferrous metal having a melting point above about 1650 DEG  F., e.g. Ni, Mo, W, Co, Cr and Ti.  The powdered alloy comprises from 5-20 % wt. chromium 7-13 % wt. phosphorus and the balance Ni, preferably about 13% Cr, 9% P and 78% Ni.  The alloy has a melting point of 1650-2050 DEG  F. and the temperature in said heating for fusion is within the range 1650-2050 DEG  F., but is at least the melting point of said alloy and less than the melting point of said base.  The time of heating at fusion temperature ranges from 20 seconds to 2 minutes.  The protective non-oxidizing atmosphere is neutral or reducing in character, depending upon the hydrogen content, which suitably varies from 0-10% H2 and the balance nitrogen; and is subject to the aforementioned critical low moisture content with, preferably, a low concentration of CO and CO2 not exceeding 0.1% by volume.  The performed alloy powder is preferably applied to the metal base in the form of a liquid suspension, the suspending liquid being, conveniently, water, but it can be glycerine, light oils &c. Starch, or surface-active agent, acting to form a relatively stable suspension or dispersion is added when water is used.  The metal base is pre-cleaned by conventional techniques to remove rust, grease, oil, dirt, scale &c. prior to application of said suspension.  Powders may range in size from 100-420 mesh, suitably 325 mesh, but smaller particle sizes down to 1-5 microns can be used.  A coated steel base can be annealed, to impart ductility and formability to the steel base and it can be temper-rolled to eliminate the yield point of the steel base.  A coated steel base is substantially free of brittle intermetallic compound formation at the juncture between said base and said coating whereby said coated base has high formability suitable for fabrication without objectionable flaking or cracking of said coating.

Abstract: 1,016,848. Reservoir for cigarettes. D. W. MOLINS and THE MOLINS ORGANISATION Ltd. Oct. 30, 1963 [Nov. 1, 1962 (2)], Nos. 41396/62 and 41397/62. Heading B8A. Cigarettes from a plurality of cigarettemaking machines fall on to the upper surface of endless conveyer 4 and are conveyed rightwards and then leftwards and are then guided by device 12 to fall into a compartment formed by a pair of upstanding partitions 20a and 20b carried respectively by two endless chains 23 which operate on vertical axes. Device 12 is provided with a shoot 11 for feeding the cigarettes down into each compartment and with a detector 13 which detects the level of a filled compartment. The endless chains 23 are moved forward to convey each compartment to the left, the bottom of each compartment being formed by an endless belt 6 which likewise moves. The two conveyers therefore form a reservoir of cigarettes each compartment of which in turn is discharged by endless conveyer 16 or by endless conveyer 31 (not shown), each arm 32 of which discharges a compartment upwards and delivers the cigarettes into a packaging machine.  Shoot device 12.-Its shoot 11 is formed narrow, so that it lies between the pairs of partitions 2Oa and 20b, and permits their free movement. The device 12 is carried by a band 15 which passes round a spring reel 24. This enables the position of device 12 to be varied along the length of the conveyers. This increases or decreases the capacity of the cigarette reservoir as needed.

Title: Closure of containers

Filed: 1972-09-07
Abstract: 1440922 Closing containers METAL BOX Ltd 5 Sept 1973 [7 Sept 1972] 41669/72 Heading B8C [Also in Division B5] A method of closing a container 5, comprises heat-sealing a portion of an indexable web 74 of closure material to the rim around the open end of a container, clamping the web between two apertured plates while a knife severs excess closure material around the entire periphery of said rim when the rim and closure material are at least partially heat-sealed to one another, and forming down around the container a portion of the severed closure material which extends around and beyond the rim of the container. The web is also damped during the heat-sealing operation. In one embodiment, Fig. 1, a pot 5 is placed in a locating block 10 for reciprocable movement towards and away from a clamping, heat-sealing and severing assembly mounted on a fixed plate 20. In the operation of this embodiment, when striker plates 12 which are movable with the locating block 10, engage the lower one of the pair of clamping plates 34, 38, the lower plate 38 is pushed upwards and the web 74 clamped. Continued upward movement of the locating block 10 and striker plates 12 causes the clamping plates 34, 38 to move upwardly against springs 71 and the web 74, now in contact with the pot rim, moves into engagement with a heated sealing tool 58. Further upward movement of the pot 5 causes the sealing tool 58 which is spring urged downwardly, to yield and a knife 46 which is fixed on the fixed plate 20, severs the covering material. In an alternative embodiment, Figs. 3-5 (not shown), the clamping, sealing and severing assembly is movable towards and away from a fixed pot locating block (10). In the operation of this embodiment, when the web (74) contacts the pot (5), the lower one of the clamping plates (118, 164) engages a fixed stop and is pushed against the upper plate (118) to clamp the web (74). Continued downward movement brings the heated sealing tool (134) into contact with the web (74) around the rim of the pot and the cutting blade (158) severs the web. In this latter embodiment, the heat-sealing tool (134) may be mounted through mating curved members (132, 152) or a high rate compression spring to allow the tool limited rocking or floating movement, respectively. In both embodiments the cutting blade is mounted around a former, e.g. 42 Fig. 1, which folds down the overlapping severed closure material around the rim of the pot. The closure material maybe inherently heat-sealable or carry a heatsealable coating, or a heat-sealable adhesive may be applied to the container and/or closure material.
