Patent GB-489955-A (GB)
Title: Improvements in or relating to rotary engines
IPC: F01C21/08
Filed: 1937-02-05
Abstract: 489,955. Rotary engines. FLUVARIO, Ltd., and GUINNESS, E. E. Feb. 5, 1937, No. 3649. [Class 110 (ii)] The engine or pump of the roller, or sliding vane, type is provided with means to move a stator 24 to decrease the eccentricity, when the fluid pressure in the delivery pipe (in the case of a pump) rises unduly. Roller vanes 29 are supported by a ring 30 in a rotor 28 to pump fluid from an inlet 22 to a delivery port 23. Pressure fluid presses on the underside of a piston 38, through a passage 32 to force up the stator against the pressure of a spring 44, when the delivery pressure is excessive. If the pump is to be reversed, plugs 36, 37, are interchanged to open a passage 33, and close 32. Hard metal liners line the end plates of the outer casing. Instead of plugs 36, 37, non-return valves may be used in passages 32, 33. Sealing rings 53 are forced into engagement with the casing as described in Specification 430,159. In Fig. 7, valves 57 are seated in trunnions 61 which may be rotated by hand, and which seal the passage 33 and open the passage 32, when 22 is the inlet port. A modified arrangement, Fig. 9, shows a stator 24 which may be rotated when fluid in the delivery 23 reaches a pre-determined figure and forces a piston 38 to turn the stator about a pivot located near the suction port 25. When the stator is rotated, the part 71 moves across the delivery port. The bearing portion 70 may be made of phosphor bronze. A sealing member 72 may be pressed upwards by a spring or fluid under pressure. This pump is not reversible so that only one control passage 32 is provided. The piston 38 may be integral with the stator. The invention is applicable to constructions described in Specifications 450,595, 450.625, [both in Group XXIX], 450,669; 450,670, [Group XXIX]. Specifications 430,159 and 474,231 also are referred to.

Title: Improvements in or relating to apparatus for tipping railway wagons and the like
IPC: B65G67/00
Filed: 1942-03-18
Abstract: 556,091. Tipping-apparatus. GENERAL ELECTRIC CO., Ltd., and MARSHALL, C. H. March 18, 1942, No. 3604. [Classes 78 (iii) and 78 (iv)] Wagon-tipping apparatus comprises a tilting frame 16, 17, having rails 13 for a wagon 12, the frame being vertically guided as by rollers 23,24 and guides 21,22 at one side only and being hoisted by ropes 29 secured thereto at that side, the ropes being passed over pulleys 30 at the top of the vertical guides, down around pulleys 31, 33 on the frame and up to winding drums 34, so that when the ropes 29 are wound on the drums the frame is first lifted until stops engage pivot pins at the top of the guides, further winding of the ropes then tilting the frame and the wagon until the latter discharges into a hopper 51. During the tilting movement the wagon is held on the frame by bolster means. The tilting movement may be about either the fixed centres 37 of the pulleys 30, or about a floating axis. In the construction shown in Fig. 1 the frame 16, 17 is L-shaped and carries rollers 23 engaging between vertical guides 21, 22, and rollers 24 engaging the guides 21. The frame carries a cradle 11 which has wagon rails 13 and is supported on the frame by an out-of-centre fulcrum pin 14, the cradle being normally prevented from tilting inwards by a roller 19 engaging a fixed bracket 20 on the main structure. When the frame 16, 17 begins to rise as the ropes 29 are wound on the drums 34 the cradle tilts inwards until the wagon side bears against pivoted bolsters 27. The frame rises until forks 36 on arms 35 on the frame engage the fixed pulley spindles 37 ; at the same time the rollers 24 on the frame engage cams 48, so that the frame then turns about the spindles 37. The wagon is clamped on the frame by bolsters 40 pivoted to a bar 39 fixed to arms 38 pivoted on the axis of the rollers 23, these arms being connected by links 41 to cables 42 passing over pulleys 43, 44 to counterweights 45. The winding drums 34 are driven by an electric motor (not shown) which is switched off by a limit switch when the wagon reaches the fully tilted position shown in broken lines. When the ropes 29 are slackened the frame turns back with the wagon and is lowered to its normal position. In the modification shown in Fig. 4 the frame and wagon tilt about a floating axis, the pulleys 30 being mounted on toothed cam members 58 adapted to roll on fixed surfaces 50 so that the frame and wagon travel laterally while they tilt.
