Title: A new or improved counter pressure machine for the delivery of draught beer
IPC: B67C3/06
Filed: 1933-02-10
Abstract: 407,175. Dispensingliquids. CHIGNELL, J., 14, York Road, Hall Green, Birmingham. Feb. 10, 1933, No. 4097. [Classes 106 (v) and 116.] In apparatus for dispensing beer in which the beer is passed from a main storage reservoir to a vessel in which it is kept under pressure and from which it is passed, before delivery, to a measuring chamber in which it is normally under pressure, the beer is reduced to atmospheric pressure before it is drawn off and an adjustable means is provided for automatically cutting off the supply to the measuring chamber when a predetermined quantity has been received therein. The operations in connection with the filling of the measuring vessel and the discharge of the beer from its delivery nozzle are effected by two valve plugs 9, 20 simultaneously rotated through links 22, 23, 24 operated by a handle 25. The measuring vessel 16, after being emptied, is filled with air at atmospheric pressure through a passage 31 open to the atmosphere and registering with a groove 32 of the plug 9 connected to a passage 15 in the body 8 of the plug 9. When the handle 25 is raised, the passage 31 is closed, and the passage 15 is connected through a channel 12 to a tube 30 projecting above the beer under pressure in the cylinder 4, raising the pressure of the air and gas in the vessel 16 to that existing above the liquid in the vessel 4. On further rotation of the valve plugs 9, 20, the channel 10 registers with a pipe 26 through which beer flows into the measuring chamber 16 from the cylinder 4 until the beer reaches the level of a nozzle 29 which co-operates with a channel 11 and a tube 28 projecting above the liquid in the cylinder 4 to prevent further flow into the measuring vessel 16. The nozzle 29 is adjustable to vary the volume of beer entering the measuring vessel 16. To discharge the beer, the handle is moved downwardly, and before it reaches the discharge position shown in Fig. 6 the groove 32 on the plug 9 registers with the passages 15, 31 so that the measuring chamber 16 is connected to the atmosphere. On further depression of the handle 25, the channel 21 of the plug 20 connects the bottom of the measuring chamber 16 to a delivery nozzle 34 through a passage 33 in the valve body 19.

Title: Improvements in or relating to methods of purifying crude phthalic anhydride
IPC: C07C51/573
Filed: 1949-02-16
Abstract: Phthalic anhydride is obtained from crude phthalic anhydride by heating a mixture of the crude anhydride and at least 0.0001 mol. per mol. of phthalic anhydride in the crude anhydride of a basic sodium salt or a basic lithium salt of an inorganic acid, or a mixture of said salts, at a temperature above 250 DEG  C., but not substantially in excess of the boiling-point of phthalic anhydride at atmospheric pressure, and then separating phthalic anhydride from said mixture in a purified form, the said salts having a pH above 7.5 when measured in a pure water solution.  The crude phthalic anhydride may be obtained from the vapour phase catalytic oxidation of naphthalene, and may contain colour and odour impurities.  The crude anhydride may be distilled before mixing it with said salts.  The temperature employed may be above 275 DEG  C., e.g. the boiling-point of phthalic anhydride at atmospheric pressure.  The heating may be continued until a distillate is obtained which is substantially free of objectionable odour and is stable on heating, e.g. for a period of 0.5 to 6 hours. Preferably, substantial loss of phthalic anhydride vapour during the heating should be avoided.  The purified phthalic anhydride may be separated by distillation at sub-atmospheric pressure, e.g. at an absolute pressure below 500 mm. of mercury.  The preferred quantity of said salt or mixtures thereof is from 0.0001 to 0.08 mol. per mol. of phthalic anhydride in the crude anhydride. Inorganic salts mentioned are sodium and lithium carbonates, sulphites, bicarbonates, orthophosphates, pyroborates and disodium hydrogen phosphate.  A number of examples are given.

Title: Magnetic data storage matrix
IPC: G11C5/02
Filed: 1960-02-09
Abstract: 870,108. Magnetic data storage apparatus. NATIONAL CASH REGISTER CO. Feb. 9, 1960 [March 3, 1959], No. 4495/60. Class 40 (9). [Also in Groups XXXV and XXXVI] A three-dimensional storage matrix comprises a stack of matrix planes 23a . . . 23g, Fig. 5, with aligned apertures 24a . . . 24t each encircled by a concentric set of coils, the aligned apertures accommodating rods 14 each of which comprises a glass filament 15, Fig. 2, having a magnetic film coating 12 with rectangular magnetization characteristics on which is wound a number of spaced series-connected coils 13 defining discrete storage regions, the rods being positioned so that each of the associated coils are located within a respective coil set. The rods are in the order of 0.015 inch diameter, and are spray-coated with silver over which a thin film of 97% iron with 3% nickel alloy is electrolytically deposited to a thickness between 800A to 5000A (see Group XXXVI), the film being either continuous as shown or having longitudinal discontinuities. An oxydization-preventing plastic layer may be applied over the films, and a further layer may be applied after the coils 13 are wound on the rods. The matrix planes are each constituted by a sheet base of non-magnetic and insulating material such as impregnated fibreglass fabric 20, Fig. 3, which is formed with co-ordinate apertures 24, a set of three concentric coils respectively for bias, writing and reading purposes being secured about each aperture by an embedding compound. Respective coils from each set are connected in series to peripheral terminals such as 21e<SP>1</SP>, 21e<SP>11</SP>. The three co-ordinate matrix is formed by cementing together a stack of matrix planes with their apertures aligned by temporarily inserted guide wires. These wires are then replaced by the rods 14 which are positioned so that each coil 13 is concentric with a set of coils in a plane. It is stated that the use of spaced coils 13 is not essential and that a single coil extending the length of the rod may be used. Two modes of operation are described. In one mode the bias winding is unenergized and currents of value - I/2 are applied to a selected series of coils 13 and to the writing coils of a plane in coincidence to store a binary one in a discrete portion of a magnetically coated rod, the current value I being the total current necessary to reverse the remanent state. Read-out is effected by a current + I applied to a series of coils on a selected rod, a change of remanent state inducing an output in a reading coil in the associated plane. Alternatively the magnetic films may all be continuously biased by a current of + I/3 value in the bias coils of all the planes, writing then being effected by coincident currents of - 21/3 and reading by a   single current of + 21/3.
