Title: Improvements in granular interpolymers and process for their preparation
IPC: C08F8/12
Filed: 1949-03-14
Abstract: <PICT:0659836/IV (a)/1> Hydrolysed copolymers of ethylene and a vinyl ester of an organic monocarboxylic acid, wherein the ratio of ethylene to the remainder of the molecule is from 1 : 1 to 4 : 1, and at least 50 per cent of the ester groups are hydrolysed, are obtained in a granular macromonecular form by bringing a stream of a solution of the hydrolysed copolymer in a volatile solvent into contact with a stream of steam, and maintaining the combined streams in a turbulent state until the solvent content of the copolymer particles thus produced has been reduced below the level at which agglomeration occurs.  When the solution of hydrolysed copolymer contains the alkaline catalyst used in the hydrolysis step, this is preferably removed by neutralization with acids such as acetic or stearic. Suitable vinyl esters are vinyl formate, acetate, propionate, butyrate, stearate, and benzoate.  The volatile solvent may be a lower alcohol, or a mixture thereof with benzene, toluene, xylene, pyridine, dioxane or trichloroethylene, or water in admixture with methanol, ethanol, acetic acid, acetone, or dioxane.  In the apparatus shown, high-velocity steam enters pipe 1 and a dilute solution of colloidal material may be introduced into the steam from inlet 2 before coming into contact with the copolymer solution from inlet 4.  The mixture is then carried along tail pipe 7 and discharged into a steam-heated catch pot 8 which contains a hot agitated liquid 13, such as water, which is a non-solvent for the copolymer, and which preferably contains a small quantity of a colloidal substance such as starch, methyl starch, glue, gelatine, casein, albumin, and sodium or zinc stearate, these forming a thin film round the copolymer particles, vaporized solvent issuing from line 11 may be recovered and re-used.  The slurry of copolymer particles is withdrawn through pipe 16, filtered, washed, and dried, providing a white granular powder of particle size from 6 to 150 mesh, which may be used in the manufacture of films, filaments, coatings, injection mouldings and extrusion products.  Specification 607,911 is referred to.

Title: Improvements in or relating to railway block telegraph instruments
IPC: B61L23/12
Filed: 1924-03-19
Abstract: 235,638. Fleming, J. March 19, 1924. Signalling any of a number of possible indications.-Railway block signalling instruments giving three different signals in both directions over a single transmission line are provided with stick relays which give a maintained indication initiated by a momentary line impulse. The line currents are of normal strength and different polarity, and of increased strength, for the three signals respectively. Impulses over the line 1 pass through two relays A, B. The former is polarized, and operated by current of normal strength, the latter responding only to current of increased strength. The armature of relay A engages one or other of two contacts 6, 18 according to the polarity of the received impulse. If contact 6 be engaged, a stick relay D is energized from a battery 5 through lead 7, indicator E, lead 15, armature of relay B, to earth. The indicator E is thus energized to give an indication corresponding with the line impulse. Armature of relay D engages a contact 10, closing a circuit by which relay D and indicator E are maintained energized, over lead 11, contacts 12 (held closed by the released armature of relay C) and leads 13, 14. Contacts 21 are at the same time opened. The indication remains until a different signal impulse is received. If the next impulse differs in polarity, stick relay C is energized from battery 17, relay D being deenergized by the opening of contacts 12. A maintained indication is given by current from battery 17 through relay C, contact 19, lead 20, contacts 21, leads 22, 14, indicator E and armature 8. This current differs from that supplied by battery 5, so that the indication of indicator E corresponnds with the changed polarity of the signal impulse. If a signal impulse of increased strength is received, relay B is operated, and the circuit is broken at contact 8. The relays C, D and indicator E are thus de-energized, and a corresponding indication is given, the apparatus then being as shown in Fig. 1. A modification is described using a throw-over switch operated by the polarized relay, and a single stick relay. A further modification is also given in which stick relays are used of the type having separate exciting and retaining windings. Circuit diagrams are also given showing two arrangements of transmitting and receiving instruments at one end of the line, together with the battery, key, &c. arrangements for transmitting the signal impulses. In one of these, the arrangements generally resemble those shown in Fig. 1. In the other, the indicator pointer is arranged between, and is operated mechanically by, the armatures of the two stick relays.

Title: Improvements in and relating to remote control systems for electric motors
IPC: H02J13/00
Filed: 1930-03-07
Abstract: 349,169. Master control of several motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Cutler Hammer Manufacturing Co.; Milwaukee, Wisconsin, U.S.A.) March 7, 1930, No. 7539. [Class 38 (iii).] Travelling to predetermined limits.-Each of the motors A, only one shown in Fig. 3, for opening and closing a furnace door is controlled locally by a drum 13, and by a master controller MC, located on a crane, through a single connection effected by a trolley T3 on the crane engaging a shoe S pertaining to the particular motor. Low voltage relay contacts 26, 27 are closed when both coils 26a, 26b or 27a, 27b of the relay are energized, but will remain closed with normal voltage with only coil 26a or 27a energized. Thus to reclose these relays after operation it is necessary to return the master controller to the " off " position. Movement of the master controller to the " open " position, provided the local controller 13 is "off," connects line L1 through coil 26a to point X, thereby short-circuiting operating coil 12a and lock-out coil 11b of reversing switches 12, 11 respectively, and fully energizing lock-out coil 12b and operating coil 11a. Reversing switches 11 thereupon close and cause closure of main switch 10, whereupon the motor opens the door until the limit switch 14 is opened. Similar circuits are completed in the " close " position of the master controller only line L2 is connected to the point X and an auxiliary contact 12e on the switch 12 completes a maintaining circuit for this reversing switch, so that the crane may proceed to another furnace while the door is still closing. On overload, coils 16a, 17a open contacts 16, 17 in the circuit between the shoe S and the point X, thereby shutting down the motor. These contacts are maintained open by coils 16b, 17b until deenergized by return of the master controller to its " off " position. A modified arrangement of novolt relays is shown in Fig. 4. Relay 40 can only be closed in the " off " position. In either running position, a second relay 41 is closed over contacts 40 and completes an alternative energizing circuit for the relay 40.

Patent GB-823297-A (GB)
Title: Process for the separation of mixtures of liquids
IPC: B01D3/14
Filed: 1957-03-07
Abstract: <PICT:0823297/III/1> <PICT:0823297/III/2> Mixtures of liquids are at least partially separated by a process comprising partial vaporization of the liquid mixture and/or partial condensation of the vaporized mixture in the presence of granular or porous sintered substances, such as quartz sand, sintered glass or granular basalt, which are warmer than the mixture, and whose infra-red vibration absorption bands overlap those of only one of the components of the mixture, so that this particular component is vaporized to a greater extent in the vaporization step and is condensed to a smaller extent in the condensation step than would be the case in the absence of the large surface solid body.  In Example (1), water containing 1 part in 7000 of deuterium oxide D2O is introduced at a temperature of 18 DEG C. through tube A (Fig. 1), at the rate of 10 ml. per minute; and it flows through a porous plate E, which is 1 cm. thick, made of sintered glass, the void diameter being 0.01 to 0.03 mm.  The temperature of the apparatus is 20 DEG  C.  At the same time, air at 20 DEG  C. is introduced through tube B at the rate of 2.1 litres per minute.  The air, laden with water-vapour, withdrawn through tube C is cooled; and the condensate is found to contain 1.1% of D2O. Alternatively, the vapour-air mixture from tube C is passed up through metal tube G (Fig. 2), which is charged with basalt grains 0.1 to 1.0 mm. in diameter, and is heated to 95 DEG  C. by means of jacket H.  The vapour-air mixture leaving tube F contains practically only H2O in the first 100 minutes of the run; while the water condensed on the basalt grains in tube G contains all the D2O. Carbon dioxide gas is then passed through tube G at about 110 DEG C., and the H2O/D2O mixture is vaporized from the grains.  The liquid, condensed from the gas outside the tube, consists of approximately one quarter of D2O.  In Example (2), dioxane-water mixture of azeotropic composition (i.e. 80% dioxane) is passed at 45 DEG  C. and at 30 ml. per min. through a 1 cm. layer of quartz sand at 60 DEG  C., together with 2.1 litres per minute of nitrogen at 45 DEG  C.  The effluent gas/vapour mixture is passed for 30 seconds into a cooling trap, and afterwards into a different cooling trap. Analysis of the two condensates and of the non-vaporized liquid shows that there has been preferential vaporization of dioxane from the azeotropic mixture.
