The actuator piston chamber 30 is supplied from a separate motor-driven pump 24 through a reversible solenoid valve and the exhaust line includes a pressure limiting valve 32 whereof the pressure on the exhaust side of the piston 21 is only slightly below that on the pressure side. In a modification the chamber 30 is formed between pistons 211, 212, Fig. 3, connected by a rod 35 and the bearing surfaces 39, pressure spaces 37 and relief spaces 38 are formed in said pistons which have supply and return circuits 161, 18. In a further modification the voltage and current supplied to the solenoids of valve 29 may be varied so as to vary the speed of piston 21 during part of the stroke and to maintain consistency of speed during the remainder of the stroke. In a further modification the coil (291), Fig. 7 (not shown), is vibrated gently by means of a frequency converter (47) resulting in gentle vibration of the rods 19, 20. Such vibration may be imparted by including a throttle valve (50), Fig. 8 (not shown), and a closed storage vessel 51 in the return line 23.

Abstract: 968,308. Rotary rubbing tools; rolling tubes. TITANIUM METALS CORPORATION OF AMERICA. Nov. 13, 1962 [Dec. 11, 1961], No. 42981/62. Headings B3M and B3V. A process for reducing a metallic tube includes the steps of plastically deforming the tube by rotating work rolls acting on the outside of the tube, so that the metal of the tube flows along the tube axis, and applying a back tension on the tube of up to 50% of the yield strength of the metal determined at ambient temperature. The work rolls may be of annular shape 14 and 16, being rotated by a frame 18 surrounding the tube, or may be discs having axes parallel to that of the tube. The tube, mounted on a mandrel 12 is reduced from a thickness 10 to a thickness 20. A draw tension sufficient to overcome the back tension and friction and to give a desired feed rate to the work is applied hydraulically. The preferred range of values for back tension is between 5 and 20% of the yield strength of the material.

Abstract: 935,769. Electric correspondence control. DOWTY TECHNICAL DEVELOPMENTS Ltd. Dec. 22, 1961 [Dec. 24, 1960], No. 44371/60. Class 40 (1). [Also in Groups XXIX and XXXI] A servomotor, as shown an hydraulic, rotary vane motor consisting of vanes 7, 8 secured to a rotary cylinder 6 and vanes (not shown) secured to a fixed spindle 9, is connectible by a clutch to a load 1 to be operated, e.g. the steerable nosewheel of an aircraft, and has means for aligning the elements of the clutch to permit engagement when the pilot selects manual steering control. The clutch consists of plungers 18 which, in their retracted positions shown, permit free castoring of the nosewheel but which, when moved outwardly by hydraulic pressure applied to pistons 22 to engage holes 19,secure the rotary cylinder 6 to the element 1. An electrical position-responsive device 35 is mechanically connected by a tube 33 to the element 1 whilst a similar device 36 is connected by a frame 30 and tube 34 to the cylinder 6, and the outputs from these two devices are normally connected in series so as to produce a resultant signal which is indicative of the positional error between the elements 1, 6. A pilot-operated switch for selecting manual steering control causes hydraulic fluid under pressure to be supplied to the pistons 22 and to a valve which controls the vane motor and is itself controlled through an amplifier by the error signal from the devices 35, 36. The plungers 18 consequently engage the holes 19 and operate levers 27 and a rod 29 to actuate a lever 31 which causes a switch 32 to interrupt the series connection between the devices 35, 36 and connect the device 36 in series with a similar device (not shown.) movable by the pilot so that the vane motor now moves in correspondence with a pilot's control. The devices 35, 36 may consist of fixed primary windings supplied with A.C. current and magnetically interconnected with fixed secondary windings by movable iron armatures. Alternatively they may be potentiometer or synchro devices.

Title: Apparatus for effecting intimate contact between particulate material and liquid
Inventor: LAW FRANK
IPC: C02F1/52
Filed: 1962-11-27
Abstract: A starter of calcium carbonate pellets is placed at the bottom of the main chamber 10 in the annular column 24.  The raw-water and lime slurry are pumped through the tangential inlet pipes 26 and injectors 28 respectively and are forced round and up the column.  Due to the tapering core which extends from 1/3 to 1/2 the height of the chamber the rotational speed of flow of the water and slurry mixture decreases as it rises in the column so that considerable turbulenece of the mixture is achieved.  The water is softened by the chemical reaction of the calcium hydroxide with the calcium bicarbonate and the solution becomes, after a short period of operations, super-saturated with calcium carbonate. The latter crystallizes out of solution and forms on the already present calcium carbonate pellets.  The crystallization is greatly assisted by the turbulence brought about by the increasing cross-sectional area of the annular column.  The pellets are carried up the column and then fall to the bottom again as they reduce speed.  The pellets fall down to <PICT:0987638/C1/1> the region of at least cross-sectional area where they are swept up again by the inflowing slurry and water.  The pellets gradually increase in size and other pellets form.  From time to time pellets are removed by means of the draw-off pipe 29.  For this purpose it is desirable to turn off the flow from the injector and inlet adjacent the draw-off pipe.  The softened water rises in the funnel-shaped chamber 12 and flows over the inner wall 14 which forms a weir.  The flow proceeds from the trough 17 through the outlet 18.  Instead of the construction of a core made up to two tapering portions a simple cone may be provided.  Alternatively the core may have a curved profile but the curve must be convex to ensure maximum velocities at the base of the chamber.
