Title: Precipitation of asphaltic and metallic substances from petroleum oil
IPC: C10G21/00
Filed: 1948-04-12
Abstract: Petroleum oils, especially distillation residua obtained during the refining of petroleum, are freed from asphaltic and metallic constituents with the aid of a liquefied normally gaseous paraffinic hydrocarbon (such as methane, ethane, propane or butane) as precipitant, the oils being fed into the precipitating zone at a point above the point of introduction of the precipitant, which latter point is substantially at the bottom of the zone. Precipitated substances are withdrawn from the bottom of the zone and treated oil from the top of the zone so that the precipitated asphaltic phase is maintained substantially above the point of introduction of the precipitant.  By operating in such a manner, the asphaltic phase comprises the continuous phase.  The residua to be treated may contain asphaltic materials having a softening point above 100 DEG F. and salts of metals such as iron, sodium, calcium, magnesium, vanadium and nickel.  The treated residua may be suitable feedstocks in cracking processes or in the preparation of lubricating oils.  The precipitation may be carried out in a vertical tower at elevated temperature and pressure and preferably with higher temperature at the top of the tower than at the bottom.  If the process is carried out in stages, wherein the first stage is operated at temperatures below those required for complete precipitation of the asphaltic substances and the treated oil from the first stage is subjected to heat treatment in at least one subsequent stage at higher temperatures whereby further precipitation is caused, asphalts of different softening points may be segregated in the respective precipitation zones.  The process may also be operated by introducing solvents for aromatics at the upper end of the treating zone, examples of such solvents being phenol and cresylic acid, introducing the normally gaseous paraffinic hydrocarbon precipitant at the lower end of the treating zone, and introducing the residuum at an intermediate point of the treating zone.  In an example, the residuum treated is a 16 per cent West Texas bottoms (the percentage being based on the total crude) having an initial boiling point in the range 800-850 DEG  F.  This is treated with liquefied propane in a tower packed with disc and doughnut packing at a pressure of 100-200 per square inch above the vapour pressure of the propane at a temperature of 90-180 DEG F.

Filed: 1947-04-21
Abstract: 636,744. Gravity-separation apparatus. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES ALAIS, FROGES, & CAMARGUE. April 21, 1947, No. 10592. Convention date, May 15, 1946. [Class 46] [Also in Group II] In apparatus for separating and forming suspensions of solids in liquids, a cylindrical settlement tank 1, Fig. 1, having a conical bottom 2 has attached to the bottom 2 a cylindrical conduit 8, of diameter equal to or smaller than that of the tank, provided with internal baffles formed by cones 10 and funnels 11, down which settled solid material flows to a discharge orifice 7, and up which passes a diluting, washing or substitution liquid from a funnel 61. Inside the tank 1 are provided a sleeve 3 and within it a cylinder 12 separated by a narrow gap from the tank bottom 2, and having a narrower portion 13 at the top. A stirrer 9 may be provided. The suspension is fed into the sleeve 3, the heaviest particles collecting upon the cone 2, and the lighter particles flowing out through a side tube 4 with the greater part of the suspension liquid. A less dense washing or substitution liquid is introduced into the funnel 61, a part of this liquid escaping with the heavy particles through a pipe 7 in a jacket 5, and the remainder flowing up the cylinder 8 where it mixes with the liquid of the initial suspension and becomes partly substituted for it. The mixture of the two liquids reaching the top of the conduit 8 flows up the cylinder 12 and through the orifice 13 into the sleeve 3. The orifice 13 is slightly above the level of the suspension inside the sleeve 3 to prevent the suspension passing into the cylinder 12. If the liquid introduced at 6<SP>1</SP> is denser than that of the suspension, the cylinder 12 may be dispensed with. The cones 10 and funnels 11 may be replaced by other mixing devices. Fig. 2 shows the conduit part of the device combined with classifying apparatus. The suspension to be treated is introduced through a tangential pipe 14, the heavy particles thus collecting on the wall of the tank 1 and by-passing a diaphragm 15 to fall on the cone 2. A suspension of lighter particles deflected by the diaphragm 15 flows upwards between two cylinders 3 and 16 and out by a tube 4 ; froth and very light particles pass upwards between the cylinder 16 and a tube 17 and out by a tube 18. Suspension containing light particles which has flowed past the diaphragm 15 returns to the supply through the tube 17.

Title: Trigger mechanism for firearms
IPC: F41A19/45
Filed: 1937-04-14
Abstract: 493,556. Automatic firearms. SOSSO, G. April 14, 1937, No. 10640. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 15, 1937.] [Class 119] Relates to automatic firearms in which a pivoted hammer 11 is connected by a link 12 to a lever 10 pivoted at 10a and carrying a pivoted catch 15 co-operating with a pawl 14 on the trigger 13. According to the invention a fixed stop 15b is provided for co-operation with the catch which then operates as explained below. When the breech block 3 is pulled back by hand for reloading in the known way, it turns the hammer 11 back and the lever 10 is thereby turned forward against the pressure of main spring 9 acting through a sleeve 8 and pins 8a, whereupon the catch 15 rocks and engages the stop 15b, which retains this mechanism in the cocked position. After this hand loading and cocking operation, the breech block 3, which in its front part surrounds the barrel, is returned forward by the spring 9. If then the trigger 13 is pulled, the pawl 14 thereon engages a bent on the catch 15 and rocks this catch out of engagement by the stop 15b. Further pull of the trigger causes the pawl to ride over the catch 15 and release the lever 10, whereupon firing takes place and is repeated until the trigger is released, when a spring 16 between the pawl 14 and the trigger causes the restoration of these parts to their normal position, whereupon the firing mechanism remains cocked. This mechanism can be uncocked by gentle hand operation of hammer and trigger, and after this uncocking can be cocked again by a mere partial pull of the trigger, a further pull bringing about firing. During the firing operation, the barrel recoils slightly against the spring 9 and by means of rack and pinion 7, 6 and lever 17 on said pinion throws breech block 3 fully back. An extractor 18 and a striker 19 with rebound spring 20 are provided in known manner. The grip 2 contains a curved magazine containing an endless belt as described in Specification 461,598. The Specification as open to inspection under Sect. 91 describes also a safety device, Fig. 4 (Cancelled), comprising a transverse member 22, which under the influence of a spring 23 normally locks the striker 19. When the trigger is pressed, it lifts a rod 24 and this wedges the member 22 aside bringing a recess 22b therein in line with the striker, which is thus unlocked. This subject-matter does not appear in the Specification as accepted.

Regulating.-Regulation of the fuel-injection air and of the fuel is obtained by a centrifugal governor connected, to the fuel valve and to the loading- spring of the reducing-valve through which the injection air passes. The governor h is shown connected by a lever f, rod d, and bell crank c<1> to a piston b<1> which bears against the reducing- valve a, so that as the speed increases, the piston b<1> is moved by the governor so as to augment the pressure of the loading-spring b and thereby increase the pressure of the injection air. The lever f is further connected by a rod k to the fuel valve m. When the highest injection pressure has been obtained, a spring i interposed in the rod d yields, and allows the rod k to close the fuel valve, thereby shutting off the fuel at excessive speeds.
