Title: Improvements in and relating to receiver-assemblies for automatic rifles and like firearms
IPC: F41A17/32
Filed: 1943-11-04
Abstract: 579,668. Automatic smallarms. WESTERN CARTRIDGE CO. Nov. 4, 1943, No. 18335. Convention date, Feb. 26, 1943. [Class 119] The rear end of the receiver 31 of a fixedbarrel automatic firearm is closed, against ingress of dirt &c., by a rotary hollow plug 88 which also, in one angular position, closes the slot 85, Fig. 23, in the receiver wall in which the operating and locking lug 38 on the breechbolt 36 reciprocates. The plug is settable into three different positions, in one of which, shown in Fig. 1, it permits normal working of the weapon; in the second position it moves the cocked hammer 70 to over-cocked position and holds it there and also, by closing the slot' 85, prevents the breech-bolt being moved rearwards from closed position beyond a limited distance sufficient to show whether there is a cartridge in the breech ; and in the third position detains the breech-bolt in fullyopen position. The plug has semicircular ribs 91 at its rear end for interlocking with complementary ribs 87 in a rear extension 84 of the receiver, and a radial lug 92 on which is hinged a finger-piece 96, an extension 98 of which provides a latch to hold the plug in its several positions. Appropriately-shaped slots 101, 103 in the plug provide, in the normalworking position, for the free movement of the breech-bolt locking lugs and the pivoted hammer 70. When the plug is rotated to the second or " safety position, a cam 102 on one wall of the slot 101 pushes back the hammer to an over-cocked position and then obstructs its return ; and in the third position, a tooth 104 at. the front end of slot 103 engages in front of the breech-bolt lug 38 and locks the bolt in fully-open position. A flexible stud 68, used as described in Specification 573,668 in the securing of the barrel and receiver to the stock, enters a transverse slot 100 in the plug and limits the extent of its rotation, so that the ribs 87, 91 cannot be fully disengaged until the weapon is stripped.

Abstract: 120,908. Seward, G. O. Nov. 19, 1917, [Convention date]. Electrolytic furnaces.-In a furnace for producing magnesium, a fused electrolyte containing magnesium fluoride carries a, quantity of magnesia in considerable excess of that soluble therein, and is of sufficient density to prevent rapid subsidence of the undissolved oxide. The specific gravity should exceed 3, and is preferably about 4. The electrolyte may contain fluorides of metals electropositive to magnesium and salts which increase the density and lower the melting-point. A suitable mixture contains 55 parts magnesium fluoride, 5 parts sodium fluoride, and 40 parts barium fluoride. The temperature of electrolysis may be 900-1000‹ C., and the current density at the cathode 400 amperes per sq. ft. The furnace comprises a cast-iron container 1 cooled at the base and encrusted with solid electrolyte 3, the pointed cathode 5 projecting through the base. Carbon anodes 9 depend into the electrolyte. Above the cathode is a cooling coil 11 which produces a crust sufficient to shield the floating magnesium from the air but easily broken when the metal is to be removed. On the electrolyte floats a layer 10 of magnesium oxide or carbonate, part of the oxide becoming suspended and combining with the fluorine. This layer also protects the anodes.

Title: Improvements in or relating to methods of growing quartz crystals
IPC: C30B7/00
Filed: 1954-06-23
Abstract: Quartz crystals are grown on seed crystals suspended in a vessel capable of withstanding high temperatures and pressures, containing a mass of particles of quartzite, a sample of which shows no blackening in the grains of quartz when irradiated with X-rays, and aqueous medium containing sodium carbonate in a concentration of 0.5 to 3.0 N, the aqueous medium partially filling the vessel so that the ratio of the volume available to it after insertion of the quartzite to the volume filled by it is between 1.18 and 1.46, the vessel being sealed and heated so that the temperature of the aqueous medium is between 320 DEG  and 400 DEG  C., the solution in the region of the quartzite being at a temperature 5 DEG  to 20 DEG  C. higher than the solution in the region of the seed crystals, the mass and surface area of the quartzite initially being such that an average daily increase in thickness perpendicular to and on each of the growing faces of the seed crystals is between 0.3 and 1.0 mms.  The sample of quartzite is tested as described in Specification 811,213.  The vessel, which is a cylindrical steel autoclave with a lid which is bolted in place, is heated on an electric hot plate in a furnace cavity, the temperatures of the solution opposite the quartzite and opposite the seed crystals being measured by thermo-couples strapped to the external surface of the autoclave.  The seed crystals are rectangular plates having their major surfaces perpendicular to the Z axis, and are suspended one above the other by platinum wires.  The quartzite is crushed into particles and sieved to obtain particles of a size to give the desired rate of growth. Sufficient quartzite is used so that one third remains unused when the crystals have grown to the desired size.  The total surface area of the quartzite particles is chosen, after experiment, so that the required temperature difference between the solution around the quartzite and that around the seed crystals, is obtained.  Specifications 792,724, 797,203 and 811,215 also are referred to.

Title: Process and apparatus for the production of soap powder
IPC: C11D13/20
Filed: 1920-07-06
Abstract: 173,791. Imhausen, A. July 6, 1920. Soap powder is produced by cooling the hot liquid mixture of soap and soda or other filler, preferably while in motion, to below the temperature of the atmosphere, even to below 0‹ C., and gradually reheating to the air temperature by a heating-medium. The cooling may be effected by blowing in cold air, or by the admixture of liquid air or other gas which bleaches the powder as it is reheated, or by saturating the hot liquid in a closed vessel with air or other gas, leaving the mass under gaseous pressure to loosen and disintegrate, and blowing it in finely divided condition intn a well-cooled chamber; or the cooling and reheating may be effected by jacketing the ccntaining-vessels or by flowing the mass in thin films on to internally cooled or heated rollers. The mixture, when cooled to 0‹ C., may be allowed to absorb liquid hydrocarbon or other solvent of fat, preferably made water-soluble, to produce a durable soap powder containing volatile solvents. In the apparatus shown the liquid mixture is passed along the channel a by propellers k on a preferable hollow and perforated shaft h while cold brine is flowed in the opposite direction through that part of the jacket d below sloping partitions e; the cooled mass falls into a second channel in which it is propelled in countercurrent to warm brine or other heating- medium in the jacket. Air or other gas may be blown in through the shaft h, the blades k may be so shaped and spaced at the discharge end as to grind the mass, the cooling-brine may be returned to the discharge end through that part of the jacket d above the partitions e, and the brine from the cooling-jacket may be used in the reheating jacket. In other apparatus the liquid mixture falls on to a nest of say five superposed pairs of rollers, the top three pairs being well-cooled and the last two pairs heated, or on to the first of a set of say seven rollers arranged horizontally, the first four being cooled and the last three heated. Preferably the first roller or pair of rollers is cooled the most.

Abstract: 296,859. British Celanese, Ltd., and Cope, E. C. July 16, 1927. Addition to 285,927. Alternating-current induction machines; driving-arrangements; motors, cooling; windings.- The electrical driving-means for spindles of spinning, twisting, doubling, winding and like apparatus described in the parent Specification, wherein very high speeds are obtained in polyphase motors without the possibility of the motors remaining at any critical speed below full speed by providing unbalanced ampere-turns in the motors or in the high-frequency generators supplying them, is arranged so that the spindles are driven from the motors by belt, cord, toothed, or friction gearing instead of being directly coupled to or forming part of the rotors. The descriptive matter relating to the electrical construction and details of the motors and generators and to the control and supply systems is the same as that in the parent Specification. A motor 23, Fig. 6 may drive a spindle by means of a belt 26, or a series of spindles may be driven by belts from a shaft directly coupled to or geared with the motor, or the motor may drive a vertical shaft carrying a horizontally arranged pulley provided with a belt passing lengthwise of the machine and engaging the spindle wharls alternately on opposite side, an additior-al row of spindles being mounted on a rail at the back of the machine and being driven by the return length of the belt. Any suitable gear ratio may be selected for the gearing between the motor and the spindles, but generally the speed of the spindles is equal to or greater than that of the motor. The motor may be coupled to a shaft 58, Fig. 8, which drives the spindles by spiral gears 65, 66, which are enclosed in casings 67 and lubricated by a continuous forced or gravity feed. To minimise end thrust alternate gears are reversely cut.

Abstract: 1471022 Venting/delivery device HAEMONETICS CORP 30 April 1974 [11 May 1973] 18926/74 Heading B8V A sealed container of liquid, e.g. saline solution is emptied using a moulded plastics by-pass spike 20, 21 or 22, that has a tip 35 for penetrating the seal 14 of the container, a passageway for liquid flow and a gas vent which comprises a central thin-walled rigid metal tube 30, preferably of stainless steel and of small diameter, said tube extending beyond the tip to prevent the vent gas being drawn out with the liquid. The by-pass spike is formed as three separate mouldings, i.e. tip member 31, central member 32, and body 33; these are preferably of synthetic resin such as polystyrene or polycarbonate and are either welded or bonded together. The tip 35 has parts 36 that preferably have smooth contours to avoid damage to the seal and which open into a flow passage 52. This in turn is connected to the space 93 by passageways 91 and 92, Fig. 9, on either side of a rectangular part 82 at the top of the central member 32. From 93 the liquid leaves via opening 90. A ring 42 formed at the end of the tip and an insert in the rectangular part 82 secure the vent tube 30, passages 80 and 84 in the part 82 connecting its interior to the space 81 and hence to the sidearm 85, which is normally connected to a source of sterile air to prevent contamination. The distance from parts 36 to the bottom of the outlet 76 and the diameter of the space 93 are chosen to maximize the flow rate subject to moulding restraints and to ensure no vent air is withdrawn with the liquid. A series of containers 10, 11 and 12 may be consecutively emptied through a single outlet 13, Fig. 1.

Title: The production of nisin
Inventor: HAWLEY HENRY BERNARD
IPC: C07K14/315
Filed: 1957-06-17
Abstract: A concentrated nisin preparation is obtained from a dilute aqueous solution of nisin produced by growing in a culture medium a nisin-producing strain of Streptococcus lactis by a process in which foam is produced from the aqueous solution in the presence of a small quantity, not exceeding 0,1%, of a surface active agent especially a non-ionic surface active agent, and the foam is then collected.  The culture liquid is transferred to an upright tube having a rotating plate at the top and air is passed upwardly through the tube, the foam collecting at the top of the tube being collapsed prior to collection by the rotating plate.  Other inert gas such as nitrous oxide, carbon-dioxide or nitrogen may be used in place of air.  The collapsed foam is treated with a salting out agent such as sodium chloride, the precipitated nisin dissolved in a solvent such as methanol and is reprecipitated by the addition of a non-solvent such as acetone.  The dilute aqueous solution of nisin may be formed by growing the Streptococcus lactis in a milk culture medium precipitating a curd of casein or paracasein from the culture medium, adjusting the pH of the culture medium to a value less than 4,5 and thereafter separating from the curd the aqueous liquid containing the nisin.
