Class 107 [Also in Groups XXI and XXXII] Means for coupling a frame 53 mounting a snow plough or scraper blade 52 to a motor vehicle 10, Figs. 1, 2 and 3, comprises an arrowhead member 57 on the blade frame 53, a slot 59 in a plate 31 forming a front part of a frame 13 attached to the vehicle, spring-urged jaws 64 which are fixed to vertical pivots 63 and may be pushed aside by the arrowhead 57 entering the slot 59 and may move into holding position behind the entered head, links 67 connecting each jaw mechanism with a disc 68 which may be rotated about a pivot 70 by a hand lever 71, and a latching mechanism comprising a lever 88 pivoted at 89 to a plate 32, which lever 88 is urged by a spring 93 into a position where its end 87 may hold the jaw operating hand lever 71 in an inoperative position. The frame 13 comprises braces 15 joined by a tie plate 17, and is provided with an adjustable member 19 having a mounting 23 by which the frame may be clamped to an axle 12 of the vehicle. The frame 13 also comprises a top brace 30 connecting uprights 28, and adjustably mounts a transverse member 35 having ears 36 fixed by pins 37 through holes 34 in the uprights 28 so that a bracket 38 may be seated on the vehicle bumper 11. The frame thus constructed and mounted on the vehicle pivotally supports a hydraulic piston and cylinder 47 which may be actuated to raise or lower the blade frame 53 through a pivoted linkage 40 and a chain 54. When the blade frame 53 is disconnected from the vehicle it is supported by a pivoted rest bar, (see also Group XXXII). In operation the blade frame supported on its rest bar is approached by the motor vehicle which is manoeuvred to enter the arrowhead in the slot. Further movement of the vehicle unlatches the rest bar which springs upwardly, and the arrowhead is caused further to enter the slot and push aside the sprung jaws 64 which snap into holding position behind the head, Figs. 4 and 5. The blade frame may then be raised or lowered within the limits of the coupling by operating the hydraulic cylinder.

IPC: B01J8/12
Filed: 1941-02-10
Abstract: 598,228. Catalytic apparatus; cracking hydrocarbons; destructive hydrogenation. STANDARD OIL DEVELOPMENT CO Feb. 10, 1941, No. 1740. Convention date, Dec. 30, 1939. [Classes 1 (i) and 32] In the conversion of hydrocarbon oils the vapours are passed through a conversion zone with finely divided catalyst under such conditions that part of the catalyst is suspended and is withdrawn with the reaction products,. and a substantial portion of the catalyst remains in the reaction zone for a considerably longer time than the vapours and is withdrawn from the bottom of the conversion zone. The vapours preferably remain in the reaction zone for 10-50 seconds and the catalyst for 15 seconds to 30 minutes; the catalyst is preferably 200-400 mesh and the vapour velocity 0.1-10 feet per second. In the illustrated embodiment, catalyst from hopper 69 is suspended in inert gas from pipe 71 and mixed with hydrocarbon vapours from pipe 10. The suspension is passed through pipe 12 to converter 13, and a further supply of vapour may be admitted at 51. Suspended catalyst is separated from the reaction products in cyclones 52 and 112, and may be returned to the reactor or treated in a stripping chamber 22, from which it passes through a depressuring chamber 29 to a hopper 33. It may be suspended in inert gas and passed into a conical regenerating chamber 45, to which a suitably cooled oxidising gas is admitted in stages through pipes 58- 60. In this step also the catalyst may remain for a considerably longer time than the gas in which it is suspended. The regenerated catalyst is separated from the combustion products in cyclones and passed through a stripping chamber similar to the chamber 22, and thence to a hopper 69 from which it is returned to the cyclone. For cracking oils the conversion zone may be maintained at 600-1200‹F. and up to 50 lbs. pressure The hydroforming of gasoline fractions is also described, at temperatures of 800-1050‹F. and pressures of 50-750 lb, a gas containing 40-70 per cent. of hydrogen being added to the reactant.

Filed: 1925-09-23
Abstract: 263,639. Spencer, H. E. Sept. 23, 1925. Filling tubes and like receptacles.-In a machine for making and filling containers, a modified form of mandrel for use in charging liquids or semi-liquids into the containers is shown in Fig. 18. The mandrel 16 contains a tube 39 open at the top to the atmosphere constituting an air passage, and the charge is fed into the annular passage 136 between the mandrel and the tube through a pipe 137. In use, discs 45, 47 are picked up by the mandrel, which descends to the bottom of the container. The bottom of a valve 143, with the washer 45, strikes the bottom of the socket 50 and moves a rod 144 upwards to close the air valve 143 and to lift a charging valve 140 off its seat 139 to allow the charge to flow into the container. The disc 45 is disengaged by the relative movement of the parts and rests at the bottom of the container. The mandrel 16 then rises until a trip causes the air valve to open and the charge valve to close.
