Title: Removal of acidic gases from gaseous mixtures
IPC: C10K1/16
Filed: 1962-01-15
Abstract: Sulphur is obtained from a solution of hydrogen sulphide in a liquid dialkyl N-substituted aliphatic amide, such solution having been obtained in a process for removing hydrogen sulphide from hydrocarbon gases by contact with the dialkyl amide in a rectified absorption column, by introducing sulphur dioxide into the lower portion of the absorption column.  Unabsorbed gases are washed in the upper part of the column to remove sulphur dioxide and precipitated sulphur is recovered from the absorbent.ALSO:Acidic contaminants, such as hydrogen sulphide, sulphur dioxide, carbonyl sulphide and carbon dioxide, are separated from hydrocarbon gases by countercurrent contact in a rectified absorption column with a liquid dialkyl N-substituted aliphatic amide; the gas is simultaneously dried by the absorbent. Specified absorbents are dimethyl, methylethyl, diethyl, propylmethyl and dibutyl formamides, dimethyl and methylethyl acetamides and dimethyl propamide.  The gas may be a flue gas, refinery gas or natural gas containing 3-90% mol. of hydrogen sulphide.  The absorption column is preferably operated at above 14 kg./cm.2 abs. and 10-65 DEG  C. with the bottom temperature 20-80 DEG C. higher than at the top of the column.  The maximum ratio of hydrocarbon and hydrogen sulphide in the solution should be 5 : 100 parts by weight. The absorbed gases may be recovered by flashing at 0.45-7 kg./cm.2abs. and simultaneously or subsequently stripping by heating and, if desired, with a stripping aid such as a C4-C12 hydrocarbon oil.  The stripped gases are washed with a C12-C18 hydrocarbon wash oil such as a gas oil to recover any gasoline hydrocarbons, the washing being effected in the top of the stripping tower or in a separate tower.ALSO:Acidic contaminants, such as hydrogen sulphide, sulphur dioxide, carbonyl sulphide and carbon dioxide, are separated from hydrocarbon gases by countercurrent contact in a rectified absorption column with a liquid dialkyl N-substituted aliphatic amide; the gas is simultaneously dried by the absorbent.

Title: Improvements in or relating to the Lubrication of Connecting Rod Bearing of Internal Combustion Engines.
Inventor: BROOK OSCAR LEONARD LEOPOLD
IPC: F16C9/04
Filed: 1918-01-25
Abstract: 122,684. Brook, O. L. L. Jan. 25, 1918. Force-feed lubricating.-A connecting-rod for internal-combustion engines is provided with a reservoir supplied by oil under pressure and forming a reserve of oil available if the pressure-feed fails. The reservoir consists of two chambers B, B<1> connected to the rod A by perforated bolts C, Fig. 3, which form oil passages between the chambers and act as baffles to restrain surging of the oil. Oil from a pressure-fed bearing A' enters the reservoir by a pipe D formed with a transverse outlet D<2>. From the chamber B the oil passes to the bearings A<2>, A<3> by overflow pipes E, F. The pipe E is shorter than the pipe D so that there is no tendency for oil to leave the reservoir by the pipe D. The pipe D may be replaced by a non-return valve placed at the end D<3>. A chamber G in communication with the reservoir discharges oil on to the cylinder walls through pipes H, H<1>. A filling- opening is provided to give the reservoir an initial charge of oil. If the connecting-rod A is of tubular section, the interior serves as the oil reservoir.

Abstract: 1,112,457. Plugboards. J. E. TAYLOR. 12 Jan., 1967 [12 Jan., 1966], No. 1666/67. Heading H2E. A multiple contact assembly comprises a fixed panel 12, Fig. 1, carrying resilient contacts 28 and a movable panel 10 carrying patchcords, and a shaft 36 rotatably mounted on the panel 12 and carrying cams 40, the assembly being such that when the two panels are placed adjacent one another with rotatable bearing elements 22 on panel 10 seating in hanger elements 34 on panel 12, the bottom of the panel 10 lies adjacent the cams 40, and on rotation of the shaft 36, the ends of the patchcords are first caused to move vertically and horizontally towards the contacts 28 and then a short distance in the reverse direction, thus providing a wiping action between the patchcord ends and the contacts and ensuring good electrical contact. Panel 10 comprises a plurality of insulating blocks 16 having apertures 18 through which the patchcords are inserted, the blocks being contained in a frame 14 provided with handles 20. Panel 12 comprises a plurality of resilient paddle contacts 28 mounted in insulating material within a frame 24, to the ends of which are attached vertical support members 30, 32. A shaft 36 is rotatably journalled in the supports 30, 32 and an extended portion of the shaft is attached to an arm 42, which when moved, causes the shaft to rotate. The arm 42 can be moved into the recess 46 in the housing 44 attached to the outer surface of the support member 30 and can be looked therein by the detent 48 engaging the recess 50 in the arm. The hanger elements 34 are mounted in recesses in the support members 30, 32 and are provided Pith a level surface 62, Fig. 2, a channel 64 and a recess 66, the latter containing a pivoted latch 68 which engages with a pin 78 mounted on a spring 76 in the hole 74. On bringing the panels 10 and 12 together the rotatable bearings 22 are placed on the level surfaces 62 and are then pushed into the depression 72 in the latches 68. The wiping action between the patohoords and the resilient contacts is effected by raising the arm 42 towards the recess 46, this motion causing the bearings 22 to rise up into the channels 64 and, after the cams have passed their maximum rise positions, to fall slightly down the channel 64.
