Title: Improvements in or relating to double-acting piston engines
IPC: F01B3/04
Filed: 1929-06-24
Abstract: 338,574. Mackenzie, D. G. June 24, 1929. Four-stroke-cycle engines.-In an engine having two double-acting co-axial cylinders 18, 19, which rotate about their own axes, the inlet and exhaust ports are controlled by the movements of the pistons 25, 26, passages such as 36 leading from the circumference to the ends to the combustion chambers. The induction and exhaust manifolds 16 and 17 respectively connect with fixed ports 16<1>, 17<1> in the cylinder casing 15. Each cylinder is surrounded by a fixed bevel wheel 31 meshing with which are four pairs of bevel pinions 29, 30 having bosses 27, 28 journaled in the cylinder walls. Spring-pressed pins 33, 34 carried by the pistons engage with sockets formed eccentrically in each boss so that movement of the pistons due to pressure in the cylinders causes the pistons and hence the cylinders to rotate. The oscillating movement of the pistons within the rotating cylinders provides the correct combination of port openings for four-stroke cycle working. The number of power strokes to each revolution of the shaft 22 is determined by the choice of ratio between the diameters of the bevel wheels and pinions. The cycles of the individual cylinders are 90‹ out of phase. Ignition is by sparking plugs (not shown) the plug leads being connected to slip rings. A cooling and lubricating medium circulates in the casing 15.

[Also in Group XXXIII] Apparatus for deflecting or constricting a propulsive jet issuing from a nozzle 2 comprises flaps 3, 4, 5 and 6 which, as shown in Fig. 2, are each cranked and mounted on a pivot 8 for movements from a position, shown in the lower part of the Figure, in which they do not interfere with jet flow, to a position shown in the top of the Figure wherein they penetrate into the jet and cause its deflection. Each flap carries an arm 15 connected by linkage 13 to a fluid-pressure jack 12, the jacks being selectively operated to produce a desired deflection. Each flap is hollow and is formed with a nozzle 9 and a rotary or flexible connection 11 to a conduit 10, connected to a source of high-pressure air and provided with a valve 16 operated by the linkage 13 so that the deflecting effect of the solid flap is supplemented by a jet issuing from nozzle 9. A divergent extension may be provided in axiallyspaced relation to the rear end of the nozzle and flaps and the divergent surfaces may have a symmetric or asymmetric curvature. In addition additional retractable deflecting elements may be provided aft of the divergent extension. The whole may be enclosed within a cowl so that ambient air may be drawn through the annular space between the cowl and jet pipe to enter the propulsive jet through the gap between the axially-spaced jet pipe and extension. An auxiliary controlling jet arranged transversely of the axis of either conduit 10 or nozzle 9 may be used instead of valve 16. An arrangement is described wherein a turbo-jet nozzle is arranged coaxially within the nozzle of a ram-jet and solid and gaseous deflecting arrangements are described for operating on the jets from both nozzles. In all of the arrangements described the flaps may be moved simultaneously in. wards to constrict the propulsive jet or jets. Specifications 691,302, 745,630 and 750,601 are referred to.

Patent GB-887874-A (GB)
Title: Purification process for isocyanates
Inventor: KANTYKA TADEUSZ ANTONI
Filed: 1959-06-12
Abstract: A process for eliminating impurities from crude organic isocyanates obtained by phosgenating primary amines in the presence of inert solvents comprises mixing the crude organic isocyanate and the inert solvent in which it is dissolved with a petroleum fraction as defined below, mechanically removing impurities thereby precipitated, and distilling the mixture to recover the organic isocyanate, inert solvent and petroleum fraction.  The petroleum fraction employed is any liquid hydrocarbon fraction obtained during the distillation or cracking of crude petroleum which contains a substantial proportion of paraffinic hydrocarbons and has a boiling range the upper limit of which is below the boiling point of the isocyanate and which is sufficiently different from that of the inert solvent to facilitate separation by fractional distillation, e.g. petroleum ether or kerosene.  The process may be employed for purifying mono-, di- and tri-isocyanates, especially aromatic isocyanates, e.g. tolylene- and diphenylmethane diisocyanate.  The solvent in the phosgenation reaction may be any solvent capable of dissolving the amine employed as starting material and the isocyanate produced, e.g. chlorinated aromatic hydrocarbons such as o-dichlorobenzene.  The phosgenation reaction mixture may be concentrated before addition of the petroleum fraction.  The impurities may be removed by filtration or centrifuging.  In examples an o-dichlorobenzene solution of tolylene diisocyanate, obtained by phosgenating tolylene diamine is mixed with petroleum spirit boiling at 115 DEG C.-125 DEG C., the residue is filtered off and the desired isocyanate recovered from the filtrate by fractionation.
