Filed: 1928-08-11
Abstract: 318,727. Thompson (Wolverhampton), Ltd., J., and Hartland, H. Aug. 11, 1928. Cleansing and purifying casks.- Relates to barrel washing machines of the type in which the clutch on the driving shaft is controlled by a cam. According to the invention the part C of the clutch is controlled by a two part lever J the part K of which is controlled by the cam H while the part M is controlled from a podal d which operates a lever S having a forked end in which the part M engages. On pressing the pedal d the part M and the clutch member move to the left and the machine starts; immediately afterwards the part K is moved into the position shown by the dotted lines in Fig. 4 by the cam H. The operator can then remove his foot from the pedal without stopping the machine. At a predetermined time the cam will draw back the lever K and the weight of the lever S and friction at the joint m will move the part M and withdraw the clutch. By keeping the pedal d depressed the machine will run continuously. A pin P prevents the joint m from articulating in the other direction.

Abstract: 511,398. Purifying hydrocarbon oils. ROSTIN, H. Aug. 11, 1938, No. 23766. [Classes 32 and 91] Hydrocarbon oils are freed from gumforming constituents and sulphur compounds by passing the oil vapours at 300 to 450‹C. over the oolitic ore minette together with reducing gases and steam. The gases and steam are used in such proportions that the minette is not entirely reduced or entirely oxidized ; preferably carbon monoxide, hydrogen or a mixture thereof is saturated with water vapour at 65-95‹C. The sulphur is eliminated as hydrogen sulphide. The treated vapours are condensed, and the liquid con- 'densate treated with salt to remove moisture, and then with powdered minette to remove traces of hydrogen sulphide. The minette is regenerated by withdrawing small portions from one end of the treating chamber, roasting it, and returning the regenerated ore to the other end. Naphtha or oils produced from coal or shale are treated.

Title: Improvements in or relating to damping or oscillation-checking devices
IPC: F16F15/28
Filed: 1929-08-03
Abstract: 337,466. Carter, B. C. Aug. 3, 1929. Crank shafts. - Torsional vibrations in internal-combustion engine crank shafts, and other oscillations, are damped by means comprising a friction actuated solid mass or a combination of a solid and liquid mass with its centre of gravity eccentric to the crank shaft journals. The solid mass is preferably in the form of bronze discs which may slide, roll or rotate to a limited extent in eccentric cylindrical cavities of slightly greater diameter than themselves formed in the balance masses. The difference in diameter is about one-twentieth of the throw of the centre of the cavity whereby circumferential movement of the mass is limited to Œ 1.5‹. The remaining space in the cavity may be partially filled with liquidwhich, by reason of its centrifugal pressure, controls the position of the mass in the cavity. The mass may be made to float or to contact with the inner or outer periphery of the cavity by varying the quantity or density of the liquid present. The liquid, which may be mercury, or a lead-tin-bismuthcadmium alloy molten under working conditions, assists in damping by reason of friction, viscosity, inertia, splash and wave formation. In Fig. 4, - the disc masses 4 are thrust laterally against friction linings 11 on the walls of one or more cavities 1 formed in a balance mass 2 forming an extension of the crankweb, by the centrifugal force on a double conical member 9 assisted by springs 12. The end loading may be regulated by the cone angle and by the density of the cone. The cone may be replaced by a ball or by a liquid-containing capsule which distorts slightly under the centrifugal pressure of the liquid. The tendency of the discs to assume a mean radial position under centrifugal force i.e. their tendency to set themselves with their centres in line with the centres of the cavity and the shaft journal, may be augmented by springs which will then influence the natural period of the mass. In one form the cone and springs 12 are omitted. and in a further form the masses are arranged in flanged box-like members sealed by screwing or welding and these boxes are attached in balanced disposition to one or more cranks not otherwise provided with balance masses. Six boxes are shown attached in equispaced relation to a crankweb, the mass centre of the added system being on the centre line of the shaft.
