Title: Improvements in or relating to compound positive displacement pump circuit
IPC: F15B11/17
Filed: 1938-04-30
Abstract: 497,546. Rotary pumps. VICKERS, Inc. April 30, 1938, No. 12960. Convention date, May 1, 1937. [Class 110 (ii)] [Also in Group XXVIII] The invention deals with a variable pressure pumping system incorporating two or more pumps which are connected in series when high pressure exists in the output line 9, or run in parallel for a moderate output pressure in the line 9. In one plant, two pumps 2, 3, driven by a motor 1, suck oil from a tank 4 through pipes 5, 6, and deliver the oil to an outlet pipe 9 which may supply pressure to a machine tool. The pump 2 has a slightly larger capacity than pump 3. For normal operation the pump 2 delivers into the pipe 7 by way of passages 11, 12, 13. A byepass 15 leads to both sides of a piston 16, having different areas under the same pressure intensity, a light spring 16 a passing to the right. A valve 8, which is described in Specification 393,761, [Group XXIX], has a piston 23a under pressure from the pipe 7 and a light spring 25. A third valve 30 is acted upon on the left by the pressure in the pipe 7, and on the right by the pressure in pipes 17, 18. When pressure rises in the pipes 9, 14, the piston 16 is moved to the left and opens valve 19 to allow the discharge from the pump 2 to pass through pipe 18 to the inlet 17 of the pump 3. The surplus oil from the pump 2 closes the valve 31, forces back the piston 30 slightly, and is byepassed to the tank 4 by way of the pipe 29. The piston 30 is designed to be balanced by pressures in pipes 28, 17, such as when they are in a ratio of 1 : 2, in which case the pumps will be delivering oil under equal pressure rises, the sum of these being the pressure existing in pipes 7, 9. Should the pump 2 fail, the pressure behind a piston 26 falls, and valve 8 will open to allow the oil to pass through a port 22 back to the tank. If pump 3 fails, the output of the pump 2 passes past the piston 30 and to the tank by way of the pipe 29.

Abstract: 700,457. Cable-joints. SUBMARINE CABLES, Ltd. May 16, 1950 [May 16, 1949], No. 13040/49. Class 38 (1). A submarine cable repeater or like housing comprises an elongated tubular casing R formed in one piece of metal of high tensile strength, within bores at each end of which are located bulkhead sections 11 enclosing a compartment W for the repeater or the like, each bulkhead having an aperture for a cable end and being located against endwise movement, and end caps Q secured to each end of the casing Fig. 1 shows one embodiment in which each bulkhead is located by a flanged ring 22 screwed thereon, the flange 22<SP>1</SP> of the ring bearing against a shoulder on the casing, the bulkhead also being welded to the casing at 11<SP>1</SP>. The bulkheads are interconnected by spacer bars 32. A gland assembly 10 for the cable end is screwed into a central aperture in the bulkhead and earthing tapes 25 on the cable are secured to the ring 22.

Fig. 2b shows a modification in which ring 22 is omitted and each bulkhead 40 fits into a counterbore 41 on the casing. Also the central gland assembly is formed ntegral with the bulkhead. The space between each bulkhead and its adjacent cap Q is divided into chambers 46, 47 by a diaphragm 45 having a bush 50 for the cable. Chamber 46 is filled with dielectric whilst chamber 47 accommodates a loop in the cable, being enlarged for this purpose by the use of a hollow gland plug and may also be filled with dielectric 47<SP>1</SP>. The bulkheads may be secured to the casing by screwing, either a full or interrupted thread being employed. Specifications 643,550 and 700,460 are referred to.

In the mechanism shown in Figs. 2 and 3, a rack 304, co-operating with escapement-mechanism 326, has pin- and-slot mounting 306, 307 on the paper-carriage 320, and is provided with a flange 330 carrying a roller 332 which engages a cam 305 pivoted on the carriage. A pinion 316 on the cam cooperates with a rack 315 on a slide 334 which is mounted on the carriage and is connected by a link 344 to a bell-crank 343 mounted on the carriage. A roller 302 on the bell-crank runs on a rail 301 which is pivoted at 350 to the framework 322.

In operation, a trial line is typed to determine the space excess or defect, and the knob 313 is then set accordingly by the aid of a scale 314 to raise or lower the rail 301 and thereby cause the cam 305 to decrease or increase the spacing movement of the paper-carriage. To adjust the mechanism for different lengths of line, the knob 312 is set by the aid of a scale 365, and the link 319 is thereby adjusted in relation to the lever 308. To facilitate determination of the number of spaces excess or defect in a trial line, a pointer on the paper-carriage reads plus or minus graduations on a margin stop.
