The lower annular member is formed in two parts bolted together to clamp between them the base of the vessel (Fig. 3, not shown) formed of assembled parallel laminated bands of the surface coated super refractory alloy, which are provided with a refractory lining. In another embodiment, Fig. 7, a cylindrical framework is formed from alloy tie rods 18 each sheathed with silicoalumina insulating fibre, surface coated refractory alloy wire 19 being helically wound around adjacent pairs of the tie-rods to form a braiding, the whole assembly after prestressing, being encased in refractory concrete and provided with a bottom similar to that of Fig. 9. In a further embodiment (Fig. 1, not shown) the casing is formed from assembled radial segments of the surface coated alloy held together by circumferential hoops or fasteners. In use the vessel may be detachably mounted in a vacuum induction furnace 26, being transferred to a subsequent working station after completion of the treatment in an outer casing having trunnions (Fig. 10, not shown) which are engaged by a transporting yoke. The outer casing and yoke allow tilting of the vessel for pouring. The outer casing also has a bottom outlet aligned with the vessel outlet 31 to allow bottom pouring.

Title: A process and apparatus for obtaining light hydrocarbons (benzines and petrols) during the low temperature carbonisation of solid fuels
IPC: C10G1/02
Filed: 1929-08-22
Abstract: 317,857. Meiro, A. Aug. 24, 1928, [Convention date]. Coking and carbonizing processes.-Light hydrocarbons are obtained from solid fuels by subjecting the latter to low temperature carbonization in a series of retorts. fractionating the liquid products and returning the heavier hydrocarbons to the retorts to be cracked in contact with the hot fuel. Finely divided dry fuel is fed by a conveyer 21 through a valved funnel 25 into the first retort 1 and is passed along by a. worm conveyer to a pipe 38 connecting with a second retort 2, and similarly with retorts 3, 4, and 5. From the latter, the coke produced drops into an unheated retort 6 from which it is discharged to a storage bin 14. Heavy oils and pitch collecting in a reservoir 15 are pumped through a line 39 to a still 7 where they mix with distillates rising by pipes 24, 32 - - 35 from the retorts 1 - - 5. Benzines and light oils are drawn off from the upper of the still by pipes 26, 27, 28; the heavy residues are reintroduced by pipes 22, 23 into the retorts. The uncondensed products and gases pass by a pipe 36 to a condenser 8 and purifiers 10; the permanent gases, which are rich in hydrogen and methane, are compressed into reservoirs 13, and are used in part to heat the retorts by combustion in a flue 19, and in part are injected into the retorts to stir the mass and to aid the formation of light hydrocarbons. The cast or wrought iron of the retorts is said to act catalytically. Suitable, temperatures and pressures are 410-450‹ C. and 0.1-0.3 atmospheres.

Abstract: 408,996. Control of motors. FITZGERALD, A. S., 433, Warwick Road, Wynnewood, Pennsylvania, U.S.A. Sept. 14, 1932, No. 25615. [Class 38 (iii).] Travelling to predetermined limits.-A motordriven escalator or like endless-band conveyer is automatically started up by a photo-electric control circuit, and is stopped by time delay means after it has travelled a distance sufficient to carry an object or person to a required point. The presence of a person at the entrance of an escalator interrupts a light beam, and a light-sensitive device 4 acts through an amplifier 18 to close a relay 16 which causes a relay 10 to close contact 19 immediately, and start the motor 5 driving the escalator. Provided the light beam is not again intercepted, the relay 10 falls, and, after a time determined by a timing device 13, closes contacts 20 to stop the motor. Instead of a time relay a condenser may be provided which is charged through an electron tube under the control of the device 4, and is allowed to discharge over a high resistance. The voltage of the condenser is applied to the grid of a further electron tube which feeds a relay for the motor starter.

Abstract: 1501914 Forming partitioned packages E I DU PONT DE NEMOURS & CO 17 June 1975 [18 June 1974] 25749/75 Heading B8C A process for forming a series of packages comprises drawing a web of material 1 into a member 3 which forms the web into a tube 5 and feeding a second web of material 6 within the tube 5 at the same rate of advancement as that of the tube 5. This second web may be formed as a tube 10, e.g. by a member 8 (Fig. 1) or may be a strip 23 (Fig. 9) which spans the tube 5 thus providing separate compartments for two different materials which are introduced through filling tubes 4, 9 with discharge ends at 4a, 9a. Alternatively, the tube 10 can be pre-formed and can also be pre-filled prior to passing into tube 5. Pairs of encircling closures 15 are applied at intervals to the partitioned tube which is then severed to produce individual packages. The longitudinal seal 20 is made by, for example, an air heater 11 and a similar device 12 is used to seal the tube 10. The tubes are advanced by pairs of rollers 13, 14, a motor 26 being controlled by signals from devices 16, 17 so that the tube 10 moves at the same rate as the tube 5. In an alternative embodiment (Figs. 5, 6, not shown) one set of rollers is arranged to engage the inner tube through the walls of the outer tube so that both are advanced together. The webs may be of plastics or a plastics laminate.
