Title: Process for the catalytic production of hydrocarbons
IPC: C07C1/04
Filed: 1937-12-02
Abstract: 510,513. Synthesis of hydrocarbons. METALLGES. AKT.-GES. Dec. 2, 1937, No. 33360. Convention date, Dec. 2, 1936. [Class 2 (iii)] In a process for the catalytic conversion of gases containing carbon monoxide and hydrogen into hydrocarbon containing more than 2 carbon atoms in the molecule a t temperatures between 150 and 265‹C., dilute synthesis gas is applied to a contact furnace under a pressure greater than 2 atmospheres, at least a portion of the hydrocarbon products are separated from the end gas which is recycled to the inlet of the contact furnace and fresh gas rich in carbon monoxide and hydrogen is admitted beyond the point of admission of the recycled end gas so that the gas undergoing the catalytic conversion always contains more than 20 per cent. of inert constituents. The catalysts employed are those known to be suitable for the Fischer - Tropsch benzine synthesis at atmospheric pressure, e.g., cobalt 33 per cent., thorium oxide 5 per cent. and kieselguhr 61 per cent. The incorporation of the fresh gas may be effected approximately midway of the reaction zone or distributed over a number of points. In this way greater uniformity of reaction is ensured and local overheating is avoided. In the drawing A denotes a contact furnace with spaced sets of contact mass A', A<2>, A<3>, A<4>. Dilute synthesis gas enters at B. Reaction products are separated at D and withdrawn at E. Part of the uncirculated gas is recycled to B and part withdrawn at G. Fresh gas is introduced at H, I, K. Other diluents may be added to the reacting gases, e.g., methane, carbon dioxide, water, alcohols or higher hydrocarbons. Substances which occur as less desirable products of the synthesis may be employed as diluents. Addition of benzine vapour as diluent increases the life of the catalyst by extracting high boiling substances which impair its activity. The proportion of diluents in the gases is greater the greater the working pressure. The synthesis may be subdivided into stages, separation of the products occurring between stages. The Specification as open to inspection under Sect. 91 comprises generally the catalytic synthesis of hydrocarbons from mixtures of oxides of carbon and hydrogen containing gases containing more than 20 per cent. of diluents. The use of end gases from a methanol synthesis or from a Fischer-Tropsch benzine synthesis at atmospheric pressure is described. Addition of gas-oil vapours as diluent is referred to. The use of pressure in the reaction together if desired with cooling is stated to facilitate separation of products at the end of the synthesis-the hydrocarbons becoming liquid and carbon dioxide being readily washed out. The pressure is preferably so high that the partial presence of reacting gases is the same as in the normal synthesis at atmospheric pressure with gases nil in CO2 and H2. Operation in stage and regeneration of the catalysts are referred to. Two examples are given illustrating modes of operation. This subjectmatter does not appear in the Specification as accepted.

IPC: B66F9/18
Filed: 1961-03-21
Abstract: 985,699. Suction lifting devices. HYSTER CO. March 21, 1961, No. 33684/64. Divided out of 985,698. Heading B8H. A fork-lift truck 188, Fig. 6, has a suctionlifting device 11 mounted on the carriage and suction is derived from the inlet of an internalcombustion engine which powers the truck as described in Specification 985,698 [Division F1]. Interlocks are provided to prevent the suction being released until the load has been set down and the truck clutch disengaged. The suction device shown in Fig. 12, has metal top and back plates and a flexible three sided curtain 454 supported therefrom. A separate front curtain which can be rolled up or let down by a motor is also provided. The side curtains are clamped to the top and back plates and supported in rectangular formation by springs 466, Fig. 15. The lower edges of the curtains are weighted by sand, lead-shot or fluid and flexible rods are incorporated to maintain a rectangular shape. To lift a palletized load the truck is driven up with the front curtain rolled up until the load is enclosed by the three sides. The front curtain is lowered and suction applied. This collapses the curtains against the load to a certain extent and pulls the load against the top and back plates. In this position the load and pallet may be lifted. The curtains may be of polyethylene film or Craft paper. In a modification, Fig. 24, the top plate is replaced by an open three-sided frame 479. The three-sided curtain is as previously described, but its top is supported by springs 466A. A front curtain 492 is controlled by a motor 471a and the operation is the same as before. In a further embodiment, Fig. 27, a load L3 is enclosed in a flexible enclosure 494 having a flapper valve 496. A suction head 493 on a fork lift truck is brought into register with the flapper valve and suction is applied to force the load against the head after consolidation. Fig. 31 shows a suction-lifting device on a straddle carrier. A rectangular plate is supported by chains 507 for raising and lowering and has side curtains 511 and an open front and back. The side curtains and front and back curtains, which can be rolled up and down, are lowered into contact with a flexible pallet 505 and suction is applied from a blower 520. Fig. 34 shows an embodiment in which the front curtain of the suction attachment is replaced by an upstanding wall 524 on a pallet 525. Fig. 39 shows a rigid vertical suction manifold 545 which has hollow retractable top and side curtains 547, 548, Fig. 40. These contain coil springs and are rolled and unrolled by air pressure to form top and side curtains which co-operate with an L-shaped pallet 524,525, Fig. 39.

Abstract: 967,720. Jet propulsion plant. COMMONWEALTH OF AUSTRALIA. Nov. 7, 1956 [Nov. 7, 1955], No. 34080/56. Headings FIG and FIJ. A supersonic air intake comprises a multishock producing body and a surface spaced from the body and defining with it the boundary of the air intake, the arrangement being such that all the shock waves produced by the body ahead of the final oblique shock wave and the normal shock wave are outside the lip of the surface, and so that the entropy rise across the final oblique shock wave is smaller than the entropy rise across the previous oblique shock wave or waves and of such value as to permit the starting shock to make the final transition. It is explained in the Specification that the condition that a double cone Oswatitsch intake will "start" is that where C R  is the area contraction ratio, A 0 /A* and A1/A* are the isentropic area ratios PT 1 /PT 0  and P<SP>1</SP>T2/PT 1  are the stagnation pressure recoveries. Similar conditions are derived for a triple cone and a quadruple cone intake.

Filed: 1945-12-17
Abstract: 605,166. Centrifugal spinning and twistin g apparatus. PRINCE-SMITH & STELLS, Ltd., and FEATHER, E. E. Dec. 17, 1945, No. 34106. [Class 120(ii)] A centrifugal spinning and twisting machine of the kind in which yarn is laid centrifugally on the inside of inverted cup-shaped rotary holders to be subsequently unwound onto bobbins inserted into the holders from below, supplementary lengths of yarn being wound above the bobbins, which bobbins are collectively movable, angularly and forwardly of the machine, is provided with means whereby the angular movement is caused to re-start the delivery rollers, thereby initiating another spinning or twisting period. The bobbins 13, Fig. 3, are tilted by a handlever 17 fixed on a shaft 15, having an arm 26 keyed upon it for movement with the lever 17 to transmit motion through a rod 28, arms 30, 32 and a rod 34 to a pivoted tappet arm 36, Figs. 2 and 7, carrying an adjustable screw tappet 39 adapted to bear against the limb 41 of an arm formed with a detent 45 arranged to co-operate with a notch 49 in a stationary but adjustable sector 50 while the delivery rollers 19 are stopped, due to their clutch members 20, 21 being disengaged, Fig. 2. The motion initiated by tilting the bobbins 13 effects the removal of the detent 45 from the recess 49, Fig. 7, and frees the disengaged clutch members 20, 21, Fig. 2, held apart by a lever 22, connected to the sector 50 by an arm 24 and a rod 25. The clutch members 20, 21 re-engage under the influence of a clutch spring. Engagement or dis-engagement of the clutch members 20, 21 may be effected independently of the bobbin tilting mechanism by manual pressure on a plunger 47, Figs. 2 and 7. As the bobbins 13 are tilted, the yarns extending from them towards the yarn holders 5, Fig. 3, are trapped by spring clips, located circumferentially of the lower openings of the holders, so as to be severed by the rotation of the holders and held by them for the commencement of a further spinning period when the delivery rollers re-start.

Abstract: 282,437. Smoot Engineering Corporation, (Assignees of Smoot, C. H.). Dec. 16, 1926, [Convention date]. Fluid-actuated valves for maintaining atmospheric pressure in the fuel bed of a furnace. A conduit 14 permitting a bye-pass flow between a point 19 of higher pressure below the fuel bed 2 and a point 20 of lower pressure above, is connected intermediate its ends by a conduit 13 to a draught regulator 11. The bye-pass 14 is adjusted, preferably by means of reducing valves 17, 18 in its two limbs, so that the pressure transmitted to the conduit 13 is the average of hat within the fuel bed, and the regulator 11 is such as to maintain this at atmospheric pressure. In the regulator described a diaphragm 24, exposed above to the pressure of the conduit 13 and below to atmosphere is connected to a leakage valve 26 the operation of which controls the effect of a motive pressure-fluid admitted at 28 and exhausting at 29 on a piston 27 connected to the flue damper 5, the arrangement being such that the damper 5 opens or closes according as the pressure in the fuel bed rises or falls in relation to the desired normal. The regulator instead of controlling the exhaust damper might equally well control the forced-draught damper 6, or a fan instead of a damper. The Specification as open to inspection under Sect. 91 (3) (a) comprises also broadly the regulation of pressure in a fluid current with the object of maintaining a desired pressure at a selected point in the flow. This subject-matter does not appear in the Specification as accepted.
