Patent GB-523036-A (GB)
Title: Improvements in or relating to liquid pressure remote control systems
IPC: F15B7/00
Filed: 1938-12-22
Abstract: 523,036. Telemotor systems. AUTOMOTIVE PRODUCTS CO., Ltd., and SIMPSON, J. K. Dec. 22, 1938, No. 37351. [Class 69 (ii)] In a liquid pressure remote control system of the kind in which a single pipe line 45 connects a transmitting cylinder A with a receiving cylinder B and the respective pistons 11, 23, are held by the pressure of springs 12, 24 against the liquid pressure, the transmitting lever 34 is connected to the pressure applying member 17 by a clutch device which permits expansion of the fluid under temperature variations to take place without affecting the lever 34, and the piston 23 has frictional loading means to provide a greater resistance to motion than the resistance to motion of the piston 11. The transmitting cylinder is connected by a pipe 62 to a reservoir C and a valve 68 normally closed by a spring 71 is opened by movement of the piston 11 in its fully retracted position in order to make up leakage. The cylinder A is of greater diameter than the cylinder B, and the spring 12 acts on a thimble 21 which presses on an arm 17 shaped as an isosceles right-angled triangle. As the arm 17 moves counter-clockwise about its pivot the leverage of the arm 17 increases as the pressure exacted by the spring 12 decreases so that a substantially constant pressure is applied to the liquid. The arm 17 is pivoted at 47 and is integral with a quadrant 46 which normally can move freely relatively to the lever 34. When pressure is applied to the lever 34 it at first moves against the action of a spring blade 56 about a pivot 53 so as to lock it to the quadrant 46 which subsequently moves with the lever. The controlled lever 35 is also fitted with an arm 31 similar to the arm 17, but the arm 31 instead of acting direct on the piston 23 acts on a plunger 33 which can move relatively to the piston and normally is locked to the cylinder B by means of balls 36 acted upon by a conical surface 41 of the plunger which is pressed towards the arm 31 by a spring 44. When the piston 23 is moved to the left by fluid pressure its end finally moves the balls 36 and then motion is transferred from the plunger to the arm 31. Owing to the greater diameter of the piston 11 a full stroke of the receiver piston can be effected by a part of the stroke of the transmitter piston.

Title: Process for purification of water
IPC: C02F1/52
Filed: 1946-12-20
Abstract: In purification of water by mixing with chemical agents, e.g., calcium hydroxide or the like, to cause precipitation and upward flow through a vessel which contains contact grains for promoting precipitation, the surfaces of which contact grains consist of or contain crystalline substances identical with the substances to be precipitated in and settled from the water, and the cross-sectional area of which vessel increases upwardly, the velocity of the water is maintained so low in the upper part of the container that very small crystals precipitated out of the water during its passage will sink downwardly against the ascending current of water in order to form nuclei upon which further precipitates may settle.  This condition is realised when the velocity is maintained, for example, at less than 4-5 metres per hour.  The container is preferably one the cross-section of which at increasing heights increases stepwise or smoothly at a rate greater than the square of the height.  For example, the bottom of the container may consist of a cone of height 2.1 metres and maximum upper diameter 1.05 metres, and the upper part may be a truncated cone of height 1.67 metres and maximum upper diameter 2.5 metres in a plant having a capacity of 20 cu. metres per hour.

Title: Arrangement for detachably connecting a bobbin holder to a suspension rail or creel of a spinning or twisting machine
IPC: D01H1/18
Filed: 1964-09-16
Abstract: The specification is directed to an arrangement for connecting a bobbin holder to a suspension rail, creel, or the like, characterized in that the connection is designed as a plug-in and turn connection against the action of resilient pressure.  In Fig. 6 (not shown) the rail 16 has two downwardly cranked rectangular ears 18 that can extend into a rectangular recess 20 of the bobbin holder 21.  On rotating the holder 21 by 90 degrees the ears 18 pass under upper wall portions 90a to secure the bobbin holder 21 to the rail 16. Fig. 2 (not shown) is a plan view of a suspension rail 14 below which is a bobbin holder 10, the bobbin holder 10 having an upwardly extending square protrusion formed with ears 12.  After the protrusion has been pushed upwardly such that the ears 12 pass through a slot 15 in the rail 14 the bobbin holder 10 is turned by 90 degrees to place the ears 12 at right angles to the slot 15 and so lock the holder 10 to the rail 14.  The square protrusion is of elastic material and on it is turned through 90 degrees, in a corresponding square part of the opening in the rail 14, it is temporarily deformed to permit such turning.  Accidental turning back is then impossible. In Fig. 16 (not shown) the rail 14 is replaced by a channel member having a slot extending along the length of its underface.  This slot serves the same function as the slot 15 in Fig. 2.  In Fig. 9 (not shown) a square plug formed with ears 29, 30, 31 is used to connect the rail 32, cover cap 33 and sleeve body 34 together in a plug-in and turn connection.  The sleeve body 34 receives the bearing (not shown) of the bobbin holder.
