Title: Improvements relating to domestic and like ovens
IPC: F24B1/18
Filed: 1926-03-19
Abstract: 254,665. Clare, L. D'A. March 19, 1926. Oven shelves are moved outwards by gravity, under control of an exterior operating handle. In the form shown, the shelf or tray T runs on rollers V carried by a frame H pivoted at the front on pins M. To cause outward movement of the shelf, the rear end of the frame is tilted upwards by a lever B pivoted at C, which through a link D and lever E causes rotation of a crank G on which the rear of the frame rests. The movement of the shelf is initiated by the crank G contacting with lugs K attached to it, and is limited by stops P which engage an upper pair of rollers. The back of the frame is prevented from rising too far by hooks 0 engaging the crank G. The apparatus may be modified so that the rear of the frame may be lowered to return the shelf, the operating lever B being provided with a gate to retain it in the desired position. Instead of resting on the crank G, the edges of the shelf may rest on the crank webs, which are formed as scroll cams the form of which controls the ratio of lift to angular displacement.

Title: Improvements in treating petroleum oil with sulphur trioxide
IPC: C10G17/09
Filed: 1949-04-26
Abstract: <PICT:0665169/III/1> Petroleum distillates are refined by treating with sulphur trioxide in a series of consecutive stages, wherein the feed oil for at least the first stage is mixed before treatment with sulphur trioxide, with an oil which has been previously treated with sulphur trioxide and separated from the resulting sludge, the sludge produced during the treatment in each stage being separated from the oil before the oil is passed to the next succeeding stage.  The sulphur trioxide employed may be a dilute gas consisting of 7 per cent of sulphur trioxide and 93 per cent of inert gases.  In the drawing, a petroleum oil distillate having an S.U. viscosity at 100 DEG F. of 350-380 seconds is passed through heat exchanger 3 and pipe 2 to a treating tower 1, and a stream of dilute gaseous sulphur trioxide is passed through pipe 4 in countercurrent flow to the oil. Gases are removed from the tower by pipe 5 and the acid oil passed by pipe 6 to a settler 7, from which sludge is withdrawn by pipe 8 and a portion of the oil recycled through pipe 10 in a proportion of from 1 : 5 to 10 : 1 parts recycled oil to oil feed flowing from pipe 13. The remaining part of the acid oil which may be filtered to remove the pepper sludge is passed through pipe 14 to chamber 20, where it is mixed with an alkali such as caustic soda, and a 50 per cent aqueous solution of an alcohol such as ethyl or isopropyl alcohol. The neutralized oil and alcohol solution of sulphonates are passed through pipe 22 to settler 23, where the alcoholic solution of sulphonates is removed by pipe 24 and the oil passed to chamber 27 where it is washed with water.  Finally the oil is passed to stripping tower 30 to remove moisture and any dissolved alcohol, which are removed through pipe 33.  The treated oil is passed through pipe 36 to reactor 37 where it is again treated with sulphur trioxide, and is then neutralized and washed by a similar series of treatments to those used in the first stage.

Abstract: 1,212,562. Draft and buffing gear. CLEVELAND PNEUMATIC TOOL CO. 7 March, 1968 [16 May, 1967], No. 11168/68. Heading B7T. Railway draft and buffing gear comprises a cylinder 11 connected to a coupler head 10 and a hollow piston 12 pivotally connectable to a railway car by means of member 13 within a sill 17, an annular space 49 between piston head 22 and a gland nut 46 being in communication with the interior of piston 12 via ring valve 27 and ports 29, and the space ahead of piston head 22 being in communication with the interior of piston 12 by metering orifice 31 controlled by a pin 32 connected to a secondary piston 33, and there being provided within the hollow piston 12 a floating piston 47 which divides the space within the piston 12 into a first portion 48 into which ports 29 and orifice open and a space open into the interior of member 13, the latter space being charged with air through a valve 64 and the remainder of the gear being filled with liquid through ports 66. The metering orifice 31 is by-passed by spring- loaded stepped valve members 61 which open to allow fluid to by-pass orifice 31 if the pressure ahead of piston head 22 is greater than a predetermined maximum. The space 55 between axially spaced seals 50 of the floating piston is vented to atmosphere through passages 54, tube 57, bore 35, space 36 and bore 59. The air charge centres the gear to the position shown under no-load conditions. Under draft loading liquid in annular space 49 passes through throttling holes 28 in ring valve 27 into the space 48 where it forces back piston 47, compressing the charge of air. Extension of the gear ceases under draft when head 22 contacts the nut 46. When the draft loading is taken off, the air charge forces the piston 47 to its neutral position and the liquid in space 48 re-enters space 49 by forcing its way past the ring valve 27 and also through the orifices 28. Under buff conditions liquid ahead of piston head 22 passes through orifice 31 into space 48 forcing back piston 47 and compressing the air charge. The size of orifice 31 will continuously vary due to the variation in the cross-section of the pin 32. Compression of the gear will cease when head 24 contacts member 13. When the buff loading is taken off the compressed air charge will re-enter the space ahead of piston head 22, causing the gear to return to its neutral position. A chevron type seal is used between gland nut 46 and the piston 12.
