Title: Improvements in or relating to endless conveyors
Inventor: HERTEL HEINRICH
IPC: B65G17/02
Filed: 1953-03-12
Abstract: 733,714. Endless belt conveyers. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. March 12, 1953, No. 6867/53. Class 78 (1). An endless conveyer belt a is normally held suspended in trough formation by a support b, formed by a network of cables, which is provided at spaced points along the length of the belt with pairs of chains c, d secured to spindles e<SP>1</SP> of pairs of wheels e propelled along a track by driving means such as an endless chain. The upper end of each chain d terminates in a hook g normally engaging a hook f on the spindle e<SP>1</SP>, whilst each chain c is connected. directly to the spindle. Rollers h on the hooks g engage rails i provided at the loading and unloading stations. At a loading station these rails are shaped so that the rollers h on engaging them are first moved upwardly and then outwardly whereby the hooks g are disengaged from the hooks f and the chains d move away from the chains c so as to open the belt. At an unloading station, the rails i are shaped so that after the rollers h run on to them, they are moved first upwardly to disengage the hooks g from the hooks f and then outwardly and downwardly whereby the edge of the belt attached to the chain d falls below the opposite edge and the material slides off the belt. The rails may be shaped whereby the detached edge of the belt is raised to effect discharge. When the loaded or unloaded belt has passed the loading or unloading station the rails i return the conveyer parts to the condition shown in Fig. 1. In a modification, Fig. 4, each pair of chains are connected to a hook-shaped member p carrying a pulley wheel p<SP>1</SP> adapted to run on a rail n which is suspended by members m from a suspension system comprising cables k<SP>1</SP>, k<SP>2</SP> connected by rigid members l. Resilient cushioning members may be provided between the wheels e and the edges of the belt, for example, at either end of the chains c, d. The driving means may be protected from the weather by a tubular shield. The conveyer belt may be arranged to have increased flexibility in its edge portions and its loadsupporting surface to include resilient pads to protect it against the action of sharp-edged material being conveyed. Furthermore, one edge of the belt may include a portion of extended width which overlaps the other edge of the belt except during loading and unloading so as to protect the conveyed material from the effects of weather.

Abstract: 548,398. Hydrogen. POWER-GAS CORPORATION Ltd., RAMBUSH, N. E., and GRISENTHWAITE, A. T. June 6, 1941, No. 7148. [Class 90] Apparatus for the production of hydrogen by the steamiron process comprises a generator 1 containing iron oxide 5, a superheater 2 containing heatstoring refractory material 6, a connection 3 between the top of the generator and the top of the superheater, and one or more air inlets 13, 14 in the neighbourhood of said connection. Reducing gas from blower 17 passes through the oxide mass, is mixed with air from blower 18, and burnt in-.the superheater. During the producing phase steam is admitted by valve 26 and the hydrogen produced passes out by valve 28. In the reducing phase all or a part of the hot gases leaving the superheater may be passed through a heat-exchanger through which the supply or reducing gas passes. In a modified apparatus a part of the hot residual gas leaving generator 1 is diverted to one of two regenerators in which it is mixed with air and burnt, while the reducing gas supply is heated by passage through the other regenerator, which has been heated by the combustion of residual gas therein during the previous reducing phase.

Abstract: 1,216,604. Polyurethanes. AMELIOTEX Inc. 16 Feb., 1968 [17 Feb., 1967; 22 Jan., 1968], No. 7680/68. Heading C3R. Solutions of substantially linear polyurethanes are prepared by reacting in a solvent (a) a prepolymer derived from a substantially linear glycol of M.W. 500 to 5000 and a mixture of at least two diisocyanates comprising a major amount, on a mole basis, of a first diisocyanate having no substituents alpha to the isocyanate groups and a minor amount, on a mole basis, of a second diisocyanate having at least one substituent group alpha to an isocyanate group, the molar ratio of total diisocyanate to glycol being 1À5-2À5 to 1, and (b) an aliphatic diprimary amine. The mixture of diisocyanate preferably contains 75 to 98 mole per cent of the first diisocyanate and 25 to 2 mole per cent of the second diisocyanate. The linear glycol is suitably a polyester, polyether or polyester/ether glycol. Preferably, the first diisocyanate is diphenylmethane - 4,4<SP>1 </SP>- diisocyanate and the second diisocyanate is tolylene-2,4-diisocyanate, tolylene-2,6-diisocyanate or mixtures thereof and the solvent is dimethylformamide. Ethylene diamine is the preferred diprimary amine. A chain terminating agent may be added to the reaction solution. In a typical example, a polyester prepared from a mixture of ethylene glycol and propylene glycol and adipic acid was mixed with a mixture of 4,41-diphenylmethane diisocyanate and an 80/20 mixture of 2,4- tolylene diisocyanate and 2,6-tolylene diisocyanate to form a prepolymer which was diluted with dimethylformamide and reacted with methylimino-bis-propylamine and subsequently with ethylene diamine and diethanolamine. Filaments may be spun from the polyurethanecontaining solutions.

Abstract: 742,858. Sink and float separation. TROTTER, F. J., ANDREWS, T., SKELTON, W. R., and HUNTINGTON, HEBERLEIN & CO., Ltd. March 25, 1953 [March 25, 1952], No. 7682/52. Class 82(2). A sink and float process comprises first effecting a sink and float treatment and then further treating the sinks fraction in a medium of higher specific gravity than that used in the first treatment, and in direct connection therewith, the specific gravity of the second medium being maintained by feed of fresh medium. The first sink and float treatment takes place in a vessel 10, such a separator as disclosed in Specifications 547,098 and 547,099 being suitable. The sinks fall down the flaring part 11 into a casing 13 for the final sinks elevator. The second (middlings) separating vessel 15 is interposed. The media for the two separators are supplied by a cyclone separator 18 fed from a pump 19. The overflow of the cyclone is fed to a density control tank 22 and fed via line 25 to the first separator. The cyclone underflow is fed to control tank 23 and then to the second separator by a line 29. It may, in addition, be supplied to the elevator casing 13. A stock medium tank 38 takes overflow from the further control tank 36 fed from the overflow of 22 and excess medium is recycled via pumps 43 and 19 to enable density control to be effected. Some of the medium drained from the middlings is pumped by 46 to a splitting device 47 from which portions of higher density medium can be supplied to the upper and lower ends of the elevator casing, The apparatus is thus arranged to maintain the body of medium in the second separating treatment of uniform density throughout. The process is stated to be particularly adapted to coal washing.
