Title: Improvements in electrical musical instruments
IPC: G10H1/18
Filed: 1937-07-28
Abstract: 499,771. Electrical musical instruments. MIDGLEY, A. H., and MIDGLEY, A. M. July 28, 1937, No. 20844. [Class 88 (ii)] In an electrical musical instrument wherein partials of the notes are produced by electrostatic means and orders of partials are controlled separately by stop contacts, a single generator element being used for co-pitch partials of different notes on the same keyboard and for the same partials of the same notes on different keyboards, the effect of coupling keyboards is obtained with an additive result by means of resistances and switches and additional sets of harmonic bus-bars for the keyboards to which coupling is made. The Fig. shows ten harmonic bus-bars S for the Swell, with which bus-bars a number of different keys m connect a particular generator element a (through key resistances i) according to the partials of the notes to which the generator element relates. The Great has a similar set of ten bus-bars G for normal playing the keys m making contacts connecting to the same generators a. The Great keys also actuate further contacts operating on ten additional bus-bars 11 normally not in circuit but which, when the Swell is to be coupled, are connected by a multiple switch n to the respective Swell bus-bars. Multiple switches o, p connect two additional sets of pedal bus-bars (not shown) respectively to the normal set of Great bus-bars and to the Swell bus-bars, for coupling Great to Pedal, and Swell to Pedal. The generators may be as described in Specification 482,284 or 501,520. There may be 12 semitone pairs of generator discs, one disc of each pair having rings generating a scale note and all its octaves. All the rings of one generator electrode are connected together and to the amplifier b. Each ring of the other electrode is connected to earth both through a condenser c, and through a charging resistance e and condenser f a leak resistance g being arranged across the condenser f; this network forms a low pass filter preventing key-clicks, and also produces reverberation. According to the Provisional Specification, the first generator electrode is connected to earth, and each ring of the other electrode is connected to the amplifier through condenser c, and to earth through the charging resistance e and condenser f; and a further resistance is inserted between the charging resistance and the key resistances, with a connection to earth through another condenser across which is arranged a regulating resistance. Also the circumferential length of the sine wave forms in a ring may be half a wave-length, the forms being at wave-length distance in the ring and the ring portion connecting them being made thin.

Title: Method of and apparatus for treating granular food materials
IPC: A23L5/20
Filed: 1956-07-06
Abstract: 807,108. Treating food granules. FRENCH CO., R. T. July 6, 1956 [Aug. 3, 1955], No. 21038/56. Class 49. In a method for treating granular food materials by means of a gas, e.g. the deoxygenation of potato or dried milk granules using nitrogen gas; the material is passed under gravity through a substantially vertical duct having a plurality of sections of small bore diameter alternating with a plurality of sections of larger bore diameter and the gas is counterflowed through the duct at a rate such that the material is fluidized in, and flows quiescently through, the sections of small bore and larger bore, respectively. A hopper 10 supplies the granules adjacent the top of the duct which is composed of pipe sections such as 17, each having a portion 18 of smaller bore diameter, alternate sections being inverted so that the ends of adjoining sections are of the same bore and are coupled at 12. Sections 23 and 27 are separated by a section 25 of uniform bore throughout so that in the deoxygenation of potato granules a nitrogen diffuser 35 can be accommodated in the duet to supply nitrogen from a tank 40. The section 29 is connected to a hopper 30 for collecting the granules. In operation, oxygen or air is washed out of the potato granules by passing nitrogen gas up the duct, the granules in the portions 60, 61 of small bore being fluidized and thereby thoroughly washed with nitrogen, while there is a steady flow of granules through the areas 62, 63, 64. Efflux of the gas is through the top of section 16 which is open to the atmosphere.

Title: Process for the manufacture of pyrene compounds
IPC: C07C41/16
Filed: 1934-07-20
Abstract: Pyrene and hydroxypyrene sulphonic acids; acid wool dyes and substantive dyes, dyeing with.--Pyrene is exhaustively sulphonated by customary sulphonating agents and promoters such as mercury salts, to give the 3 : 5 : 8 : 10 tetra-sulphonic derivative. Pyrene already sulphonated in the 3, 3 : 8, or 3 : 10 positions may also be used. The product may be converted by means of strong alkaline agents into a compound in which one or more of the sulphonic groups have been replaced by hydroxy groups.  According to examples: (1) pyrene is sulphonated with a sulphuric acid monohydrate with or without the addition of kieselguhr, or with sodium sulphate and sulphuric monohydrate; (2) pyrene-3-sulphonic acid is similarly sulphonated to give the tetrasulphonic acid; (3) pyrene 3 : 5 : 8 : 10-tetrasodium sulphonate is converted into a 3-hydroxy-5 : 8 : 10-trisulphonic acid, a dihydroxy-disulphonic acid, and a tetrahydroxy-pyrene, by means of caustic soda, milk of lime or aqueous ammonia.  The tetrahydroxypyrene may be methylated or easily converted into naphthalene tetracarboxylic acid, and the hydrolysis with ammonia produces a 3-amino-5 : 8 : 10-trisulphonic acid as a dye-product. The hydroxy-sulphonic acids dye wool from an acid bath and may be after-treated with basic substances such as triethanolamine, hexahydroaniline, and barium hydroxide, or chromates, to give yellow to brown shades. The tetrahydroxypyrene has affinity for animal and cellulosic fibres and yields brown shades on after-treating with chromates.

Title: Improvements in hydraulic or pneumatic programming apparatus
IPC: F15B15/24
Filed: 1962-06-02
Abstract: 982,003. Fluid pressure apparatus. F. G. GRISLEY. June 4, 1963 [June 2, 1962], No. 21343/62. Heading F1P. [Also in Division B3] A programming apparatus for a machine such as a drill, mill or capstan lathe, comprises a cylinder 1 having pressure fluid supply pipes 14, 15 and an internal longitudinal groove 2 communicating with a tank or with the atmosphere through apertures 3, and with the inside of a rotatable sleeve 9 through selectively aligned holes 21 therein, the holes being circumferentially and axially spaced to determine the particular programme of movements to be carried out by a piston 11 slidable in the sleeve 9 as a result of differential pressure on opposite sides thereof, and having a rod 12 secured thereto for controlling the machine. In operation pressure fluid from a common source is divided into two streams, each stream passing through an adjustable flow restrictor and a flow indicator to thereafter act on either side of the piston 11. The flow restrictors are adjusted to create the required pressure differential and to compensate for the different effective areas of each side of the piston 11. If one of the holes 21 is aligned with the groove 2 in the cylinder, fluid can discharge through the apertures 3 and the piston therefore moves to cover the hole 21 whereby the force acting on the piston balances and the piston 11 comes to rest over the hole. When the piston is to be moved to a new position a pinion 25 engaging a geared flange 24 on the sleeve 9 is rotated to align another hole 21 with the groove. Alternatively the flange may be formed with ratchet teeth whereby the flange can be periodically rotated by a pawl or push rod. Fig. 6 shows a programming apparatus wherein the piston 11 completes part of its stroke quickly and the remaining part at a slower speed. In operation fluid ahead of the piston initially discharges through the hole 21 aligned with the groove 2 and a pipe 26 having a restrictor 27 until the piston covers the hole 21 whereby fluid is discharged through the pipe 26 only.

Title: Process for the production of alkali and alkaline earth metal borohydrides or reactio mixtures containing them
IPC: F01C21/08
Filed: 1965-05-20
Abstract: Alkali metal and/or alkaline earth metal borohydrides, or mixtures containing them, are produced by reacting mixtures of alkali metal or alkaline earth metal borates and sodium oxide with a reductant in the presence of hydrogen at or above atmospheric pressure and at 100-800 DEG  C.  The reductant is an element whose oxides are not reduced by hydrogen under the reaction conditions or a compound of such an element; the M2O (or MO) : B2O3 ratio is less than 3 : 1 (M is the alkali or alkaline earth metal); 1-1.3 moles of sodium oxide and 1-1.2 moles or gram-atoms of reductant are used per gram-atom of boron. The reactants are introduced at or near the top of a vertical shaft, the upper portion of which is maintained at the ignition temperature of the reactants.  Examples of reductants are silicon and ferrosilicon (FeSi).  The upper third of the vertical shaft may be maintained at the ignition temperature, e.g. 350-550 DEG  C. The product may be discharged on to a conveyer, carried through post-reaction zones heated to 450-520 DEG  C. and then through a coating zone. Substances which give off their water of crystallization when heated and thereby promote contact of the reactants, e.g. Na2B4O7. 4H2O may be added to the reaction mixture.

Abstract: 446,252. Cathode-ray tubes. COSSOR, Ltd., A. C., Highbury Grove, London.- (Assignees of Ardenne, M. von; 19, Jungfernstieg, Lichterfelde, Berlin) July 23, 1934, No. 21531. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 23, 1935]. Application for addition to 442,500. [Class 39 (i)] Different parts of the screen of a cathoderay tube for television reception &c. are maintained at different potentials. In a tube with compensation for the inclination of the screen as described in the parent Specification, blurring of the picture point due to its varying distance from the cathode as the ray is deflected is prevented by making the inclined screen carrier or screen 1 of resistance material and passing a current across the screen between edge clamps 2, 3 connected to a battery B so that the potential of the screen varies from one edge to the other. The screen may be made by cathode sputtering and may be maintained at a potential relatively to the preceding accelerating electrode or connected to the anode of the electron gun. The ray currents are insufficient to set up a voltage drop in the screen. Picture errors with circular symmetry such as spherical aberration may be compensated by passing a current from the centre to the periphery of a circular screen.
