Title: Improvements in methods of transmitting controlled motion to apparatus at a distanceby means of a column of fluid
IPC: F15B9/10
Filed: 1939-06-16
Abstract: 530,641. Fluid-pressure servomotor: control systems. BENNETT, R., and EWING, A. June 16, 1939, No. 17671. [Class 135] In a remote control apparatus the position of the controlled member is determined by the pressure of a column of fluid from which there is continuous leakage when the member is stationary in any position within its range of movement, while the column is replenished under the control of a valve subject to the pressure of the fluid column and loaded by means which may be adjusted to vary the pressure of the column and thereby bring about a corresponding change in the position of the controlled member. In the form shown in the Figure the operation of a spring-loaded single-acting power piston 14 is controlled by varying the compression of a loading spring 10 acting on a pair of differential pistons 1, 2 working in a liner 4. The larger piston 2 has a series of horizontal recesses 17 on its periphery extending to within a short distance of the lower end so that when the piston is moved downwards by compressing the spring 10 fluid entering by the conduit 12 between the pistons passes to the conduit 8a leading to the power cylinder and builds up pressure therein to move the power piston an appropriate distance and restore the piston 2 to its normal position. In this form the conduit is provided with a bleed port 9 adapted to be closed by a conical part 6 on the piston when the piston is in its lowest position. In a modification the bleed port is fitted with an independent throttle valve. When applied to a ship's steering gear two control valves are actuated by a see-saw lever coupled to the steering wheel by a pinion and toothed quadrant and control the operation of a double-acting piston fitted with centralizing springs. This piston is arranged to actuate a piston relay valve working in a ported follow-up liner connected by a bell-crank with the rudder servomotor.

A pipe composed of a lining of PTFE and bonded layers of fabric impregnated with PTFE is reinforced with a metal tube embedded in the fabric layers and of such a length that the fabric layers extend beyond at least one end of the tube. The pipe is built up by first helically wrapping a strip 11, Fig. 1, unfused PTFE on a mandrel 10 and covering it with a helically wrapped strip 12 of strived PTFE tape and one or more layers 13, 14, 15 of glass fabric pre-impregnated with PTFE. The assembly is then wrapped round with unimpregnated glass fabric tape and heated to fuse or sinter the PTFE and bond the layers together. After removal of the glass wrapping, a metal, preferably tempered steel, tube 16, of less length than the assembly is applied and the exposed end or ends of the assembly is/are wrapped with layers of impregnated tape 17, 18 up to the thickness of the metal tube. A layer 19 of unfused PTFE film, layers of impregnated glass tape 20, and a final layer of unfused PTFE are then applied. The threads of the fabric layers adjacent one end are arranged on the bias to facilitate the formation of a flare 23. The whole assembly is then wrapped with unimpregnated glass fabric and heated to fuse or sinter the PTFE and bond the layers together. To adapt the pipe for use as a sparger, a reinforced tube of PTFE, 33, Fig. 3, closed by a plug 34, is secured in the end of the pipe so that it overlaps the end of the metal tube, and apertures 37 are drilled in the wall of the assembly. The pipe can be mounted in the wall of a vessel by providing it with a flange 24 having a tapered bore 25 lined with PTFE and accommodating a tapered plug 27 forced into place by a member 28.

Title: Improvements in the absorption of olefines and in the manufacture of oxygenated organic compounds therefrom
IPC: C07C29/06
Filed: 1932-06-23
Abstract: Sulphuric acid is concentrated to about 82 per cent strength in ordinary lead apparatus, and further concentration is then effected in vessels of lead alloyed with a little copper.ALSO:In the successive absorption of propylene and ethylene from gases containing them, absorption of propylene in an acid is followed by absorption of ethylene in the same acid at a lower concentration.  Absorption of propylene may be effected in sulphuric acid of 80--90 per cent strength at atmospheric or raised temperature and pressure, but preferably in 87 per cent sulphuric acid at 20--23 DEG  C. and 10--25 atm. pressure; absorption of ethylene may then be effected in 75--85 per cent, sulphuric acid, preferably at 90--130 DEG  C. and 10--25 atm. pressure.  Each absorption may be promoted by the presence of a catalyst, e.g. silver oxide, ferrous ammonium sulphate, mercurous sulphate, or sulphate of silver, calcium, lead, iron or copper, and instead of sulphuric acid other acids such as phosphoric acids or strong sulphonic acids may be used.  The gases treated may be cracking gases, which may be generated under the same pressure as that applied during the absorption, and may be preliminarily enriched in olefines, as by liquefaction, and (or) treated to remove olefines higher than propylene, as by scrubbing the gases with 60--65 per cent sulphuric acid at 90--110 DEG  C. or with 80 per cent sulphuric acid at 0--15 DEG  C.  The absorption products may be worked up to alcohols and (or) ethers by dilution (if necessary) followed by distillation; dilution may be effected with water or with the alcohol or aqueous alcohol corresponding to the olefine absorbed; the subsequent distillation is preferably effected below 120 DEG  C. and if desired under reduced pressure or in a stream of inert gas. After the distillation, the residual acid may be concentrated for re-use; concentration of sulphuric acid to about 82 per cent strength may be effected in ordinary lead apparatus, and further concentration in vessels of lead alloyed with a little copper. Specification 401,269 is referred to.
