Title: Improvements relating to hose and like couplings
IPC: F16L37/252
Filed: 1940-05-27
Abstract: 540,156. Hose pipe couplings. WILSON, W. B., and SUTCLIFFE, R. U. May 27, 1940, No. 9309. [Class 99 (i)] In a hose-pipe or other coupling a sleeve 2 which is free to rotate on a pipe connector 7 is forced against a collar 4 having a bull-nose 5 which engages a sealing ring 10 housed in an extension 1 of the pipe-connector 6. To connect the pipes, projections with inclined faces on the sleeve 2 are passed through recesses in the part 1 and by a bayonet-like movement the parts 1 and 2 are forced together by a wedge action. Projections 11 and 12 enable the parts to be gripped during the make and break of the joint. To secure the part 2 to its connector a screw 14 is forced against a fibre pad 13. If necessary a tool, Fig. 4, such as a short pipe length may be applied to the grips 11, 12, to increase their leverage. A screw-driver 16 in the tool is adapted for use with the screw 14.

Title: Improvements in or relating to ratiometer type indicating instruments
IPC: G05F1/00
Filed: 1951-04-23
Abstract: 681,677. Electric correspondence control system. LIQUIDOMETER CORPORATION. April 23, 1951 [May 8, 1950], No. 9373/51. Class 40 (i) [Also in Group XXXVI] A ratiometer type instrument comprises a pointer attached to a magnetic armature whose angular position is determined by the currents through two or more coils angularly arranged round the armature, the coils being inter-connected in a circuit including a potentiometer movable by e.g. a float for measuring liquid level, in such a way that movement of the potentiometer slider from one end to the other causes the armature and pointer to rotate in linear fashion through approximately 300‹. As shown for an arrangement containing six coils, 4, 6, 8, 12, 14, 16 (Figs. 1-5) each coil consists of two half windings, 4A, 4B &c., assembled on a soft iron core 26, supported between end plates 22, 24 of non-magnetic material, symmetrically around a rotatable magnetized armature 18. The magnetic circuit for each core 26 is completed by a pole shoe 28 at one end, and a soft iron disc 30 at the other. The armature 18 is secured to a shaft 32, carrying at one end a pointer 36 moving over a scale -38, so that the position of the armature 18, shown by the pointer 36, is determined by the direction of the resultant field of all the windings 4-16, which is dependent on the relative current passing through each coil, which in turn depends on the position of the slider of the potentiometer 42. The number of turns in each coil is arranged to give linear relationship between the angular displacement of the armature 18, and the position of the slider of the potentiometer. Circuits are given for other instruments employing six coils, and also for two and four coils. Specification 642,551 is referred to.

[Also in Groups XIII and XXIX] A method of controlling the electrical resistivity of bodies of ion exchange material, e.g. membranes 17, 18 or fillers, during operation of a multi-membrane electrodialysis cell 11 through which liquids to be treated are passed, comprising extracting heat from the effluent (ducts 79, 80) and adding heat to the influent (ducts 77, 78), including the heat extracted, the total amount of heat added being less than the difference between that contained by the effluent and that contained by the unheated influent. A pump 53 delivers liquid to be desalted via a unit 13 (see Group XXIX) which controls the pressure of the liquid, a heat exchanger 12 and temperature-actuated mechanisms 14, 15 (see Group XIII), to the ducts 77, 78 which lead respectively to the dilution and concentration chambers D, C of the cell 11. The effluent from each set of chambers leaves via the ducts 79, 80 and traverses the heat exchanger 12, the duct 79 incorporating further mechanisms 14, 15. The mechanisms 15 are bimetallically-operated valves which by-pass liquid through ducts 56, 57 upon a predetermined high temperature being attained. The mechanisms 14 are bimetallically operated heat exchangers which regulate the supply of a heating or cooling fluid through lines 65, 66. Electrolyte is passed successively through end chambers 21, 22 from a supply line 81 to an outlet 83, also traversing the heat exchanger 12. The electrodes 19, 20 are platinum, and the membranes 17, 18 comprise a mixture of 72% by weight ion-exchange resin and 28% polythene which has been pressed, heated and irradiated. In a modification, Fig. 5 (not shown), two cells are connected in series, the diluent from the first cell passing straight through the second before dividing, both portions traversing the heat exchanger but one portion first becoming the concentrate for the second cell. The concentrate from the first cell traverses the heat exchanger as in Fig. 1. Details of cell operation are given, including flow rates, temperatures (e.g. 70‹ C. to 110‹ C.), voltages and amperages (e.g. 1.0 to 2.5). In one test, the apparatus was operated under a pressure of 30 1b. per square inch. Specification 796,149 is referred to.
