Title: Process for polymerizing a rubber-monomer solution
IPC: C08F279/02
Filed: 1963-04-03
Abstract: Polymeric materials of improved gloss/impact strength balance are made by polymerizing a solution of a rubbery polymer of a conjugated diene in a monovinyl aromatic hydrocarbon or halohyrocarbon, the polymerization being carried out in bulk, at least until phase inversion has occured, and wherein: (a) the agitation intensity is maintained at a level insufficient to cause any appreciable shearing of the rubber until phase inversion has occurred, (b) after phase inversion, the intensity of agitation is increased to a level sufficient to cause shearing of the particles of rubbery polymer and this intensity of agitation is maintained until the rubber particle size has been reduced to the desired degree, and (c) the agitation intensity is then decreased to a level insufficient to cause further shearing of the particles of rubbery polymer and is maintained at this level throughout the remainder of the reaction.  The shear rate in the second stage of polymerization is preferably at least 1000 sec.-1. The examples describe forming a solution of a butadiene-styrene copolymer in styrene, polymerizing it in bulk until stage (b) of polymerization is complete, then transferring the mixture to an aqueous medium in which polymerization is completed in suspension.

Title: Improvements in, or relating to, Grenades, Bombs, Mines, Shells, or other like Apparatus.
Inventor: HUMPHRIS FRANK
IPC: F42C14/02
Filed: 1917-09-18
Abstract: 129,004. Humphris, F. Sept. 18,1917. Mines, land.-Consists of a fuse for stationary mines, &c., comprising a casing or plug-piece readily attachable to the body containing the explosive charge, and having arranged in a well-like recess and in three longitudinal perforations all the igniting-devices, including a time-fuse and a pivoted hammer. Figs. 1, 3, and 5 show the application of the invention to a grenade. The detachable casing has three longitudinal holes through its body part a<2>, accommodating a tension spring h, Fig. 1, and a time-fuse j, leading to a detonator k, Fig. 3. The detonator is preferably contained in a removable plug k'. The spring h is attached at one end to a pivoted hammer c, mounted in the recessed end of the casing, the hammer being normally held in the potential position, (shown in Fig. 5), with the spring extended, by a plate g slidably mounted between guides d<2>. When the spring is thus extended, a wad p carried by it, Fig. 1, closes a vent-hole p<1>; but whenthe hammer is released, and pulled down by the spring h so as to strike the ignition cap f and fire the time-use, the wad p uncovers the vent. The fusecasing is, in the construction shown, secured at its inner end to the grenade body by a cap i, which is filled with wax, resin or like composition, serving to seal up the ends of the bores in the plug a<2> and thereby prevent a flash from passing and causing premature detonation. The outer end of the casing fits closely against a seating in the body of the grenade, or like charge-container, and it may also be screwed in at this end, or secured by screws &c. passing through lugs. A cover-plate l closes the mouth of the recess containing the striker, and this cover, through which the release-plate g passes, carries a pillar (not shown) to which a folding finger or ring-piece m, attached to the plate g, can be secured by a safety-pin, which mav be withdrawn by hand. In use, the withdrawal of the slidable plate g, to release the igniting-mechanism, may be effected by means of an attached cord.
Patent GB-764833-A (GB)
Title: Improvements in or relating to treatment of glyceride oils
IPC: C11B3/06
Filed: 1954-05-07
Abstract: <PICT:0764833/III/1> Fatty oils containing gums and free fatty acids are purified by mixing with the oil, separately or as an aqueous solution, a quantity of a volatile alkali and a quantity of water sufficient to precipitate at least some of the gums of the oil as hydrated volatile-alkali gums, and separating mixture into an oil phase and an aqueous phase containing the hydrated gums.  The alkali may be ammonia, monomethylamine or dimethylamine.  Sufficient ammonia may be used to react with part or all of the free fatty acids to produce soaps.  The ammonia may be separated as vapour from the aqueous phase and re-used.  The separated gums or gums mixed with fatty acids may be used for many purposes, e.g. as emulsified and antioxidants.  In a plant for de-gumming only, the oil from a tank 10 and ammonia solution from a tank 20 in controlled amounts are mixed and passed through a heater 14 and an agitator 16 to a separator 17 such as a centrifuge, to produce degummed oil at 24 and ammoniated gums at 25.  Only a small amount of ammonia is required.  Gaseous ammonia may be used from tank 20, water being supplied from tank 31. The gums discharge to a vacuum still 26 for recovering the ammonia and water, which are condensed in 28 for re-use.  A larger amount of ammonia may be used to react with the free fatty acids to produce an aqueous phase containing aqueous ammoniated soaps and gums.  The ammonia is recovered as before and the proportion of gums to fatty acids in the product may be varied by blending the oils treated or by varying the quantity of ammonia added.  The mixed gums and fatty acids may be fractionated into a predominantly fatty acid fraction and a predominantly gum fraction by using water to hydrate the gums and separating, or by using solvents for the fatty acids.  The oils may be purified in two stages comprising degumming by ammonia in the first-stage and removal of fatty acids in the second-stage by ammonia or other alkali.  The gums or gum soap stock material may be de-oiled in an extractor with an oil solvent immiscible with water such as a hydrocarbon or chlorinated hydrocarbon, e.g. propane.  The gums may first be precipitated with water from the oils and then treated with ammonia before further processing.  The purifying process may be applied directly to the miscella obtained in the solvent extraction of oil from seeds.

Patent GB-495335-A (GB)
Title: Improvements in or connected with electric remote control systems with protective arrangements
IPC: H02P1/04
Filed: 1937-05-13
Abstract: 495,335. Protective cut-out arrangements. M. & C. SWITCHGEAR, Ltd., and MORRISON, R. May 13, 1937, No. 13476. [Class 38 (v)] In a remote-control system of the kind wherein a machine, for example, a coal-cutter, is controlled from a remote main switch over a circuit including a control switch and resistance at the machine, pilot and earth leads extending to the main switch, and an operating relay controlling the operating circuit of the coil of the main switch (contactor), the control of the machine is effected by a simple make- and-break switch at the machine, and resistancevariation necessary to give a relatively-high secondary starting current, followed by reduced running current, is effected automatically on closure of this switch by the automatic insertion in the secondary circuit, on energization of the contactor-operating circuit, of an additional resistance constituted by a fault-tripping relay coil which, or an additional part of which, is brought into the secondary circuit to establish the running condition. Manual closure of the isolating switch C at the gate-end box A energizes the transformer E and prepares the circuit of the operating coil 6 of the main contactor D, which circuit is completed by closure of a switch 7 by a relay 9 through a swinging arm 13 and toggle 14, when a circuit from the secondary of transformer E is made over the earth and pilot conductors 4, 5 by closing a manual switch 12 at the machine B. The circuit also includes part of the winding of a fault relay 8 having a tap 11 connected to a change-over switch 10 which is operated by closure of D to insert the whole winding in circuit. The machine B can be stopped by opening switch 12. When a short-circuit between 4, 5 cuts out the limiting resistance 15, the coil 8 breaks the toggle 14 and opens switch 7 to stop the machine. Coil 9, however, remains energized and holds arm 13 in position, and the arrangement is such that the toggle 14 cannot be re-made and switch 7 reclosed until, after the fault is removed, switch 12 is first opened to de-energize 9 and release the arm 13, and then reclosed. The toggle can also be broken by a no-volt coil 16 across the supply. In a modification, Fig. 2 (not shown), relay 9 directly operates a contact 7 which is in series with an auxiliary switch operated by the increased current flowing in fault-relay 8 when a short-circuit occurs in the protective circuit, the switch being maintained open until, after removal of the fault, the switch 12 is opened. D.C. operation of the protective circuit may be obtained by means of a rectifier.

Title: Apparatus for detecting postage stamps
IPC: B07C3/14
Filed: 1972-03-23
Abstract: 1355781 Photo-electric detection of postage stamps H HUDLER 23 March 1972 [30 March 1971] 13590/72 Heading G1A Postage stamps on items of mail are detected photo-electrically by scanning the stamp serrations. Light from a source 3 is incident at grazing incidence on the letter, moved at constant velocity V on belt 1. The photo-detector nears the light reflected from the edges of the serrations via a slit, which is oriented parallel to the illuminated sides of the serrations. Alternatively, to avoid errors due to the letter-detector distance variations, two crossed cylindrical lenses may be used with a slit in front of the detector, Figs. 2b, 2c (not shown). To cover the area within which under international regulations the stamp should be stuck, a staggered array of photo-cells may be used, connected with respective circuits to an OR-gate which operates a switch to allow only the photo-cell output which corresponds to detection of serrations to pass, Fig.4 (not shown). The output circuit of the (or each) detector 4 comprises an amplifier tuned to the frequency which will be generated by the passage of serrations across the field of view of the detector. When the amplitude of the amplifier is above a certain threshold (A) Figs. 5a-c (not shown) and it lasts above this threshold for a certain duration (until B) as tuned by a timer 6, in the form of a resistance-capacitance integrator circuit, or a counter of a preset member of pulses, it is evident that a stamp has been detected and switch 8 is actuated. Shorter interference pulses either do not reach threshold A or do not last as long as B. The detection device is orientable to be able to detect the brightest reflections, and the light source is rotatable in correspondence. If stamps have different serration pitches e.g. in accordance with value, a plurality of amplifiers tuned to different frequencies are used and checking and sorting according to value is possible.
