Title: Antiinfectants
IPC: A61K33/24
Filed: 1954-11-05
Abstract: An anti-infectant preparation for medicinal use comprises at least one reducing agent having a chain of not more than six carbon atoms and an enediol group, a nongaseous oxidizing agent capable of oxidizing the enediol group in aqueous medium, and a substance capable of yielding ions of at least one of the metals, copper, iron, manganese, nickel, cobalt or zinc, as a catalyst for the oxidation, any aqueous phase present contacting one only of the enediol and oxidizing constituents prior to use.  Peroxides, e.g. hydrogen or carbamide peroxide, or alkali metal percarbonates or perborates are the preferred oxidizing agents and may be present in substantially equimolar proportion to the enediol compound.  Enediol compounds specified are ascorbic, reductic and dihydroxy-maleic or dihydroxy-fumaric acids, reductane and water-soluble salts or derivatives e.g. esters, thereof.  The catalyst, which preferably yields copper ions, is present in a proportion of from 0.00003 to 0.01 mol of copper per mol of enediol compound, or from 0.000004 to 0.0004 per cent by weight of the preparation.  The oxidizing and reducing agents are kept separately and the preparation kept free from moisture e.g. in water-free vehicles such as paraffin, olive oil or glycerol, and are not brought together in the presence of water until the time of application.  The preparation may be preserved in the form of water-free powders, tablets or ampull  by granulating the reaction mixture and coating the particles with sodium silicate, or in the form of water-free pastes made up with glycerol.  The final pH of the preparation, between 5 and 8, may be obtained by addition of sodium hydroxide or carbonate, or citric acid, either after the hydration of the water-free preparation, or to each component prior to mixing.

Title: Improvements in signal or smoke rockets
IPC: F42B10/18
Filed: 1946-10-30
Abstract: 617,738. Signalling rockets. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY. C. Oct. 30, 1946, No. 32172. [Class 9 (ii)] A rocket comprising two casings 1, 2, one casing containing a propellent composition and the other casing containing a signalling composition is so constructed that the two casings are axially movable relative to each other and maintained in spaced relationship during flight. The front casing 1 contains a propellent composition 5 held in place by an annular clay plug 4 and an annular choke 3, the front of the casing being closed by a clay plug 6 and a wooden plug 7. The rear casing 2 contains a smoke-producing composition 10 held in place by a rear clay plug 9 and choke 8 and a forward clay plug 11 and a frusto-conical plug 12. A central flash passage 13 is provided through the plugs and composition in the rear casing 2. On the rear casing 2 is a collar 14 carrying two sleeves 15 through which pass rods 16 rigidly held in sleeves 17 welded to a collar 18 fixed to the front casing. The rods 16 carry stops 19 on their free ends to limit their forward movement relative to the rear casing. The rocket is' fired by inserting the rear casing 2 in the barrel of a discharger with the rods 16 outside the barrel and the collar 14 resting on the muzzle. The flash from the cartridge of the discharger ignites the smoke composition and passes through its central passage to ignite the propellent composition in the forward casing. As the propellant burns, the gases generated drive its casing forward and the stops 69 on the rods 16 engage with the collar 14 to carry the rear casing forward spaced from the front casing by the rods 16. In an alternative arrangement, the front casing is of greater diameter than the rear casing and has an apertured extension in which the rear casing is housed until the rocket is fired. Upon firing, the front casing moves forward, an annular stop at its rear end engaging with a flange at the forward end of the rear casing to tow the latter, whilst the propellent gases escape through the apertures in the extension. In both constructions, the outwardly burning compositions may be replaced by inwardly burning compositions. Pressed cylinders of the compositions are then held away from the walls of their respective casings by projections. A fuze is then led from the propellent composition through an orifice in the conical plug between the smoke composition and the wall of the rear casing and connected to the free end of a fuze leading to the smoke composition. The latter fuze may be a delay fuze. The smoke composition may be replaced by other signalling compositions. A sliding tail may be provided on the rear casing in both arrangements.

Title: Mechanism for controlling the force of impact of the type faces in electric typewriting machines
IPC: B41J7/92
Filed: 1956-10-23
Abstract: 793,419. Typewriters &c. ADLERWERKE VORM H. KLEYER AKT.-GES. Oct. 23, 1956 [Oct. 24, 1955], No. 32316/56. Class 100(4) In a power operated typewriter having means for adjusting the force of impact of the type faces, the case-shift lever also adjusts the force of impact so that both upper and lower case characters produce the same impression. When manual control 18 is rotated clockwise, bar 8 is moved to the left by lever 14, rotated anticlockwise about 13 by pin and slot 7, 2, and held in the resulting position by pawl 24. In moving anticlockwise, bar 8 moves stop bar 10 clockwise about pivot 12, thus allowing the type bar actuating member to remain longer in contact with the power roller and resulting in a heavier impresion being produced. On depressing the shift key, member 27 is turned clockwise about 29 by cam 31 rotated by shaft 30 through a clutch, not shown. Pin 28 turns plate 3 anticlockwise which increases the anticlockwise movement of bar 8, the clockwise rotation of stop bar 10, and the force of the blow of the type face on the platen, thus ensuring equal impressions for upper and lower case characters.

Title: Process for the conversion of hydrogen iodide to iodine
IPC: C01B7/14
Filed: 1957-10-16
Abstract: In converting hydrogen iodide to iodine, a liquid aqueous solution of HI is dispersed as very small droplets in an atmosphere containing a partial pressure of molecular oxygen of at least 0.7 kg/cm.2, preferably 1.4-7 kg/cm.2, and maintained at at least 50 DEG  C., e.g. 80-150 DEG  C.  The H1 concentration should not exceed the concentration of HI in the constant boiling mixture of HI and H2O at the pressure used, and the droplet size should be not greater than 500 microns average diameter, preferably 200, or less.  Any dispersing nozzles may be used, but a gas atomizing nozzle discharging direct into a reaction zone, and using the O2-containing gas as atomizing gas, is preferred.  There may be agitation in the reaction zone. The molecular oxygen may be alone or in admixture with inert gas, e.g. commercial oxygen, oxygen-enriched air, or air, and should be in at least 25% excess, preferably 50%-100 fold.  H-ion catalyses the reaction, and acid material catalyst may be included in the HI solution, e.g. clay cracking catalysts, heavy metal salts of strong mineral acids, phosphoric acid, or one, or more, alkane sulphonic acids.  I is recovered by decantation, if liquid, or filtration, if solid, from the aqueous HI.  I in the HI solution may be recovered by adding a strong oxidizing agent, e.g. chlorine, to oxidize HI to I, and decanting I, or by passing inert gas through the solution, recovering I from the gas, and recycling the solution to the reaction zone.  I may alternatively be recovered from the gas phase of the reaction by cooling and separating I from the resultant water.  The HI conversion may be effected in two or more stages, with the same or different catalyst, or without catalyst, with, or without, I removal, and HI concentration, by fractionation, between the stages.  The process may be used to recover I from processes, which employ I to remove H atoms from organic materials, and give rise to HI solutions by quenching effluent gases.

Title: Improvements in electric inductor relays
IPC: H01H36/00
Filed: 1936-11-26
Abstract: 485,666. Electromagnetic relays. EXPRESS LIFT CO., Ltd., and WELLS, L.E.W. Nov. 26, 1936, No. 32399. [Class 38 (v)] In an inductor relay suitable for use with electrically-operated lifts, an armature 14, normally attracted to a pole 5 and serving to complete a path for magnetic flux between the pole 5 and another pole 6, is released when a sheet of magnetizable material (not shown) comes between the poles 5, 6 and the magnet 4 that supplies them with flux. The poles 5, 6 are separated by a considerable air gap 31 from the magnet 4, but U-shaped strips 7, 8 of magnetizable material arranged between the magnet and the poles serve to convey enough flux to the poles to attract the armature except when this flux is diverted by the sheet of magnetizable material. Release of the armature 14 allows contacts 17, 19 to come together, and a quick decisive action is provided by a second magnet 26 which is shielded from the magnet 4 by a magnetic shield 27. Resilient buffers are provided to cushion the movements of armature and contacts. The armature is pivoted on a knife edge 12 against which it is pressed by a spring-urged rubber washer 22. In the case of a lift system the relay is mounted on a lift and the magnetizable sheet is fixed in the lift shaft. Specification 460,585 is referred to.

Title: Improvements in pulverizing mills
IPC: B02C15/12
Filed: 1932-11-16
Abstract: 401,115. Ball-and-ring mills. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London. Nov. 16, 1932, No. 32449. Convention date, Nov. 16, 1931. [Class 59.] In a pulverizing-mill the sifting air current passes to the inside of the lower row of balls and then divides into streams which pass between the balls 13 and through orifices 14a in the rotating ring to the outside of the upper rows of balls and through a screen 43 past the inner row of the upper rows of balls. As shown a ring 14, perforated with air passages 14a and fixed to a rotary shaft 16, drives a lower row of balls 13 on a stationary track 12 and two upper rows of balls 17, 18 retained by independent non- rotary tracks 19, 20, the track 19 being pressed downwardly by springs 21 and the track 20 by springs 22. A conical shelf 42 extends from the side 10 of the mill to the top of the track 19, the free edge being adjustable to vary the space for the passage of air and fines to the outlet 26. The outlet 26 is provided with an adjustable extension, flanged inwardly at the end and extending into an open-ended cone 44 in which coarse material is deposited and returned to the row of balls 18. Material to be ground enters the mill through an inlet 11 and passes to the balls 18 and after being partly ground proceeds to the balls 17. The track of the balls 17 is higher than that of the balls 18 so that coarse material tends to remain in the track 18. According to the material to be pulverized the flow may be accelerated by reducing, omitting or reversing the elevation of the outer track of the balls 17. An annular adjustable baffle 24 surrounds the balls 17 and the material passes this baffle and falls to the lower ring of balls 13. Air which may be heated is drawn into the mill through an orifice 25 and through passages 25c to the inside of the balls 13 where it divides into two streams, one passing through the balls to the outside of the baffle 24 and the other passing outwardly through the gaps 14a and through a bar screen 43. The air passing outside the baffle 24 carries the fines between the cone 42 and track ring 19 to the inside of the cone 44 and thence to the outlet 26. The coarse material which does not pass the screen 43 returns to the lower row of balls 13. The air carries the ground material to a pair of cyclone separators, the residual materials being discharged by a fan to a second pair of separators.

Title: Improvements in or relating to process for making polypropylene film
IPC: B29D7/01
Filed: 1961-09-12
Abstract: Biaxially oriented film of stereo-regular polypropylene is produced by extruding a molten flat film of the polymer through a slot die at a temperature below 290 DEG C., pulling the film away from the die at a linear speed at least three times the rate of extrusion, quenching the film to a temperature below 40 DEG C. within a distance of 1/8 to 3 inches from the die, reheating the film to 95 DEG  to 160 DEG C., and stretching the film transversely while at the latter temperature. The transverse stretch ratio may be any ratio below about 8:1.  The film may thereafter be stretched in the linear direction to increase its linear orientation.  In an example, stereoregular polypropylene having a birefringent melting point of about 170 DEG C. and a "reduced specific viscosity" (the ratio of the absolute viscosity of a 0,1% solution of the polymer in decahydronaphthalene at 135 DEG C., to the absolute viscosity of the solvent at 135 DEG C.) of 3 is extruded at 232 DEG C. through a slot die at 4 ft./min. and the molten film is pulled away from the die at the rate of 24 ft./min. into a bath of water at 4 DEG C. spaced 0,25 inch from the lips of the die.  The quenched and linearly oriented film is then passed through an enclosed tenter chamber at the rate of 26 ft./min. and in the first 50 inch length of the chamber is heated to 123 DEG C. without being transversely stretched.  In the second 50 inch length of the chamber the film is heated to 160 DEG C. and transversely stretched by means of conventional tenter clips to twice its original width. In the third 50 inch length of the chamber the film is allowed to cool without further transverse stretching and upon leaving the chamber is edge-trimmed and wound.  Films which have been produced in the prescribed manner may subsequently be stretched in either or both planar directions without loss of their initial linear orientation and without splitting or wrinkling.
