Title: Process for effecting endothermic reactions of hydrocarbons in the presence of catalysts
IPC: C10G11/18
Filed: 1943-01-06
Abstract: 568,298. Cracking oils ; dehydrogenating butane. UNIVERSAL OIL PRODUCTS CO. Jan. 6, 1943, No. 265. Convention date, Dec. 8, 1941. [Classes 1 (i) and 32] In processes for the catalytic conversion of hydrocarbons, e.g. cracking, dehydrogenation, &c., of the kind in which the hydrocarbons are reacted in suspension with the catalysts which are thereafter separated and regenerated with an oxygen containing gas and returned to the conversion zone, additional combustible material is supplied to the regeneration zone so that the catalyst is heated to such a degree that the amount of heat units contained therein are sufficient for effecting the endothermic conversion reaction without supplying external heat thereto. The apparatus comprises an endothermic reactor 3 with superposed regenerator 24. Hydrocarbon vapours are supplied through line 1 and are mixed with catalyst issuing from a pipe 39 through opening 42. The suspension passes upwardly through a perforated distributing plate 4 supporting a relatively dense mass of catalysts. Reacted vapours pass through conduit 7 and a series of separators 6, 10 where catalyst carried off by the vapours is separated and returned through lines 8, 11 to below the surface of the catalyst bed, the vapours passing through line 12 to the usual fractionating and recovery plant. The catalyst is transferred continuously through conduit 15 where it is stripped from residual vapours by steam or process gases admitted through line 16. The catalyst then flows down tube 21 and is admixed with regenerating gases fed through line 22, the injector action of the gases transferring the catalyst through line 47 to the regenerator 24, the regenerated catalyst being returned to the reactor through the pipe 39. The used gases pass off through line 27 and are separated from catalyst in separator 26 and then flow off through line 30 and coil 44 in heat exchanger 32 where the residual heat of the gases is used to preheat air admitted through line 33 ; the preheated air then flows through line 35 to line 37 where it is admixed with extraneous fuel, e.g. in liquid, solid or gaseous state admitted through line 50, this fuel being burnt in the regenerator 24 and serving to supply the extra heat units required by the catalyst for the endothermic reaction. The process is described with reference to the conversion of butane to butenes by heating normal butane to 580‹ C. and passing it through a reactor in contact with catalyst heated to 640‹ C. and comprising a mixture of chromium oxide and alumina. The catalyst being regenerated is raised to the required temperature by admixture with further air preheated to 400‹ C. and mixed with coke equivalent in amount to 1.2 kg. per kg. mol. of butane. Specification 547,130 is referred to.

Abstract: 747,556. Type -- printing telegraphy. AUTELCA AKT.-GES. Jan. 8, 1953 [March 18, 1952], No. 654/53. Class 40 (3). In teleprinter apparatus for use at a subscriber's station wherein the operating magnet of the receiving apparatus is connected in a local energizing circuit controlled by a sensitive relay connected in the subscriber's loop, the need for delicate adjustment of the normal operating magnet and the detrimental effect on its change-over time, due to the fact that the magnetic force on the armature varies as the square of the air gap while the mechanical resetting force depends linearly on the deflection of a spring, are overcome by providing the operating magnet with two electromagnets, the one effecting the operative movement and the other the restoring movement of a common armature which has no resetting springs. As shown, an operating magnet EM, comprising two electromagnets EM1 and EM2 acting in opposition on a common armature A, is connected in the local energizing circuit and controlled by the change-over contacts ir of a polarized relay IR in the subscriber's loop. Thus the appropriate winding EM1 or EM2 is energized in accordance with pulses in the subscribers' loop and the armature A takes up the respective position without any opposition from the means to move it in the reverse direction (which only comes into operation when required).

Title: Improvements in infantry guns
IPC: F41C23/06
Filed: 1936-01-10
Abstract: 471,891. Infantry guns. COLEMAN, C. J. Jan. 10, 1936, No. 853. [Class 119] To enable a gun to discharge moderately heavy projectiles without danger or discomfort when the gun is fired from the shoulder, the gun barrel a, provided. with a breech-block c is slidably fitted into a tube f, a firing-pin x is arranged in the breech-block, a trigger l is mounted on the tube f, and means such as a rod k is provided to operate the firing-pin when the trigger is pulled. The tube and the barrel are preferably tapered down towards the front. The barrel is normally retained in the tube by a spring catch h, which yields to the recoil when the shot is fired ; the gun barrel is then ejected rearward from the tube, which is thus relieved of heavy shock. A pistol grip or a butt i is provided on the tube to facilitate the holding of the tube over the shoulder of the marksman. The trigger l is controlled by a spring t, and may be locked at safe by a catch m. The rod k is cocked against a spring r by a handle kl, and has a collar s for engagement by the trigger. When the rod is released by the trigger, its rear end enters the breech-block and strikes one arm of a lever v pivoted at w, and the firing-pin x, which is on the other arm of the lever, fires the cartridge d. The firing-pin is normally held in the retracted position by the action of a spring y on the lever v. The breech-block c may be provided with a buffer, which cushions the shock when the barrel strikes the ground after ejection from the tube. The buffer shown comprises a cylinder 2 containing a coiled spring 3 and formed with a vent 4 covered by a spring flap 5 having a small vent 6. The flap lifts to allow quick escape of air when the spring is compressed, and the small vent 6 allows a slow re-entry of air, preventing a quick return of the spring. The cylinder 2 may be connected to the barrel by a bellows 7, which keeps the parts enclosed to prevent entrance of dirt. The cylinder 2 may be connected to the tube by a chain to prevent complete separation of the parts. A tubular extension may be screwed to the cylinder 2 and its rear end formed with a cupped flange to roll on the ground and to support the gun when firing at high elevation, for example against aircraft.
Patent GB-578776-A (GB)
Title: Improved process for the production of motor fuels
Filed: 1943-01-18
Abstract: Gasolines of low acid heat are produced by cracking high boiling hydrocarbons catalytically at 800-1000 DEG  F., fractionating the cracked products to isolate a fraction having an end boiling point of 400 DEG  F. and freed from C4 and lighter boiling hydrocarbons, and reforming this fraction catalytically at 800-1000 DEG  F., the reformed product being fractionated to separate a gasoline fraction therefrom.  Catalysts specified are silica and alumina gels preferably a mixture containing 5-30 per cent alumina.  The pressure in the second stage is preferably maintained higher than in the first stage.  The C4 and lighter fraction separated in the fractionating stages are alkylated.  The charge oil, e.g. gas oil topped or reduced crudes, vaporized in coil 12 and separated from liquid content in drum 14 is superheated in coil 17 to 800-1000 DEG  F. and then passed into one of a pair of catalyst chambers 21 alternately on run and undergoing regeneration.  The cracked vapours pass off through lines 22, 23 to a fractionating tower 24 from which fractions boiling higher than gasoline are removed through lines 25, 26, the lighter vapours passing overhead through a cooler 29 maintained at a temperature to condense the butanebutene fraction.  The condensate obtained is separated in tower 31 from cracking gases (hydrogen and hydrocarbons having one to three C atoms in the mol.) and then passed to a debutanising tower 34 where fractions containing hydrocarbons having four or less C atoms are vaporized.  The debutanised fraction then passes through line 37 to the reforming stage comprising a heating coil 38 and a pair of catalytic convertors 41 alternately "on stream" and undergoing regeneration.  The reformed products are fractionated in tower 44 to recover a gasoline overhead through cooler 53 to separator 54, and heavier fractions through 51, 45, the latter fraction being recycled through line 47 to the heating coil 38.  The <PICT:0578776/IV/1> unstable aviation grade gasoline is fed through line 58 to a tower 59 for further rectification a stabilised fraction being recovered through line 62 while propane, butane, &c. fractions vaporized are recycled through line 61 to condenser 67. Excess butane-butene fraction produced during the cracking is alkylated by passing the vapours from the debutanising tower 34, 59 through a cooler 67 and separator 68 to an alkylating plant comprising alkylation chamber 72 provided with alkylation catalysts, e.g. sulphuric acid, halogenated sulphuric acids, metal halides, a settling chamber 75 and washer 82, the products being fractionated and separated in towers 84, 94.  Specifications 543,968 and 551,663 are referred to.

Filed: 1996-02-08
Abstract: With this system, guide rails (3) can be mounted in a lift shaft in a time-saving manner by swinging them into a fastening plate (1) and subsequently securing them with a wedge (2). The guide rails (3) are connected to one another by means of a push-in part (4) whose rectangular cross-section fits into an identical, internally profiled rectangular cross-section of the guide rail (3). The push-in part (4) is firmly installed, for example, at the top end of each guide rail (3), and the next upper guide rail (3) is in each case slipped onto the lower guide rail. The joint (8.1) between the guide rails (3) with the push-in part (4) cannot collide with the fastening point, because, as viewed in cross-section, the push-in connection is located outside the fastening mechanism. This means that joints (8.1) and fastening points can be at the same height without being mutually intrusive and that there is a free choice as regards the local positioning of fastening points and joints.
