Title: Improvements in or relating to the treatment of gases
IPC: C09B35/02
Filed: 1930-07-17
Abstract: In the process according to the parent Specification, in which hydrogen and carbon dioxide are produced in the removal of carbon monoxide from town gas by passing the latter together with steam over calcined dolomite at high temperatures, the process is so operated that during the whole or portion thereof the temperature is such that there is a definite predetermined vapour pressure of carbon dioxide above the absorbing material.  The process may be carried out in two stages, in the first of which carbon dioxide is completely absorbed and in the second, incompletely absorbed, the gases from each stage being mixed in the desired proportions.

Title: Process of purifying hydrocarbon oils containing sulphur
IPC: C10G29/10
Filed: 1926-09-03
Abstract: 270,626. Standard Development Co., (Assignees of Fischer, H. G. M., and Addems, W. J.). May 8, 1926, [Convention date]. Mineral and tar oils, purifying.-Liquid hydrocarbons are desulphurized by treatment with sulphur in presence of an alkali and a preformed sulphide of a heavy metal e.g. lead or copper. The oil may afterwards be distilled up to about 320‹ F., with or without vacuum or steam or both, and the distillates may be treated with alkaline plumbite. Treatment with acid, e.g. sulphuric acid of 66‹ BÞ, may precede the distillation. The sulphur may be added dissolved in hydrocarbon oils or as an aqueous solution of an alkali metal sulphide or polysulphide. The lead sulphide may be formed in the body of oil, e.g. by adding sodium plumbite and passing in sulphuretted hydrogen. In an example 5500 barrels of kerosene are agitated, as by air, with 2020 lb. of flowers of sulphur, 1100 lb, of lead sulphide, and 2500 gallons of 15‹ BÚ, sodium hydrate solution at atmospheric temperature for 1¢ hours, allowed to settle, and distilled until the still residue is reduced to 8 per cent.

Abstract: 211,080. Swan, Hunter, & W. Richardson, Ltd., and Belyavin, P. April 19, 1923. Eccentric - and - lever-actuated pumps ; stroke, varying.- The fuel admission valves of an internal combustion engine are arranged around a central starting valve in the cylinder cover midway between the axis and the circumference and in double acting engines around the piston rod at the crank shaft end. All the valves in one cover may be supplied by one pump, or each valve may have its own pump. The suction strokes of the pumps are effected by springs h<3> and controlled in length by cams j<1> and levers J, Fig. 2. Groups of pumps may be worked by a single eccentric L Fig. 3 through levers K having arms of different lengths, by which either the lengths or the duration of the delivery strokes may be made to differ. A pump of short stroke may have a plunger of a correspondingly larger diameter. By these arrangements the pumps may be cut out in succession they may start their delivery strokes at different times and a pump that starts earlier than the others may deliver a light fuel to start combustion.

Abstract: 646,904. Cutting out garment patterns. JONSON, H. C. A. Aug. 24,1948, No. 22322. Convention date, Sept. 19, 1947. [Class 141] '[Also in Group XXIII] A method of determining the position at which a fabric web is to be cut into pieces corresponding to the length of a pattern lay-out for one or more garments comprises combining a reproduction of the lay-out with a lattice pattern having longitudinal and transverse graduations, laying out the fabric web over a cutting-off table with corresponding graduations and ascertaining, by reference to the reproduction, whether any defect in the fabric occurs in an unsuitable position on the pattern. The reproduction may comprise a photograph of the pattern lay-out inserted into a graduated frame or a graduated transparent case. Alternatively, a photograph of the pattern lay-out together with a graduated frame pivotally mounted along one longitudinal side of a pattern lay-out table, may be taken. A suitable cutting-off table is provided with a transverse groove in its surface at the zero line of the longitudinal graduations with which groove are associated a rotary cutter-disc and an electric driving motor.

The fabric web is drawn out over the table for a sufficient distance from the zero longitudinal graduation and clamped in position. If necessary, the length is adjusted to insure that any defect does not occur in an unsuitable part of the pattern and then the web is cut off along the transverse groove.

Title: Improvements in or relating to variable-speed and reversing gear suitable for driving aircraft propellers and other applications
IPC: F16H61/02
Filed: 1932-08-10
Abstract: 387,607. Variable - speed and reversing gearing; propelling aircraft. CASSAGNE, G.R., Avenue Greynemer, Cazaud, Gironde, France. Aug. 10, 1932, No. 22436. Convention date, Aug. 10, 1931. [Class 80 (ii).] An epicyclic train is controlled frictionally by a single control member so as to reduce speed gradually and pass readily into adjustable reverse so as to facilitate the landing of an aircraft fitted with such propelling-gear. Aligned driving and driven shafts 1, 9, Fig. 1, are secured to a sun gear 2 and to an internal gear 7, respectively, which mesh with planets 3 supported in a loose carrier 5. Upon the spindle 4 of each planet 5 is a brake disc 24, Fig. 3, upon which brake shoes 22 pivoted at 21 are normally held by springs 23. The gearing now turns forwardly solid. The manual control (not shown) contracts a brake band d 12 which thrusts inwards rollers 17 and through toggle links 20 releases the grip of the shoes 22 on the discs 24. The discs 24 slip round so that the drive on the gear 7 is eased and the speed of the propeller shaft 9 reduced. Further contraction of the band 12 disengages the shoes 22 so that the propellers (not shown) are free to be turned by air resistance. The band 12 on still further contraction arrests the carrier 5 so that the propellers revolve backwards at a speed which is immediately responsive to hand control. A form is described with single planets in which the controlling brake is moved axially instead of radially. A form with stepped planets is described in which, in the disconnected position of the gearing, the manual control lever applies a brake to the driven or propeller shaft. The Specification as open to inspection under Sect. 91 comprises also an arrangement without means for braking the planet gears. The means for obtaining forward drives variable by slipping comprises centrifugal clutch shoes supported resiliently on the planet carrier and adapted to grip the driven internal wheel, the centrifugal action being assisted by electromagnets on the periphery of said wheel. A manual band brake acts on the planet carrier to reverse the drive. This subject-matter does not appear in the Specification as accepted.
