Title: Improvements in or relating to demodulation arrangements for frequency-modulated or phase-modulated signals
IPC: H03D3/14
Filed: 1960-10-17
Abstract: 938,267. Frequency discriminators. SIEMENS-SCHUCKERTWERKE A.G. Oct. 17, 1960 [Oct. 19, 1959], No. 35588/60. Class 40 (5). In a Hall effect frequency discriminator the longitudinal electric and transverse magnetic fields are respectively derived from the frequency or phase modulation input and from a resonant circuit 2, 3 coupled to the input and tuned to the mean frequency and producing a phase shift during the frequency swing. The output at 7, 8 is then, due to the average 90 degrees phase displacement between the fields, a carrier of twice the input frequency and amplitude modulated by the modulation signal, which may then be filtered out. Alternatively, the demodulated output may be taken from two elec-' trodes at the electric field output end of the Hall plate and the electric field output connected to a centre-tapped resistance between the two such electrodes (the magnetic field due to circuit 2, 3 being transverse to the plate as before).

Patent GB-397001-A (GB)
Title: An improved process for obtaining blanc fixe
IPC: C09C1/02
Filed: 1932-12-19
Abstract: A process for obtaining amorphous barium sulphate by dissolving barytes or substances containing the same in a salt melt such as sodium chloride or sulphate which is then introduced into water or aqueous salt solution is characterized in that the surface of the melt entering the dissolving medium is enlarged to such an extent that almost instantaneous dissolution of the fusion salt and separation of the barium sulphate occurs.  Such enlargement is advantageously effected by allowing the melt to enter the dissolving medium as a stream not exceeding 2 cms. in diameter. The degree of fineness of the granule is controllable.  Greater fineness is obtained by raising the temperature of the melt substantially, e.g. 100 DEG  C., above its fusion point, the use of a melt rich in barium sulphate, e.g. 60-70 parts barium sulphate per 100 parts sodium chloride melting at 730 DEG  C., or by increasing the temperature and concentration of the saline solution.  A very fine granule is obtained by employing a melt at 900-950 DEG  C. Coarsening of the granule is obtained by increasing the height through which the melt falls so that it is near the setting point on entering the solution and employing a dissolving medium of low temperature and concentration.  The fineness may thus be controlled by allowing salt liquors of the desired temperature and concentration to flow through the solution vessel for the melt.  Cooling coils may be employed.  A temperature of below 70 DEG  C. or above 90 DEG  C. up to boiling point should be used; in the intermediate range, steam is released explosively.  In a preferred embodiment of the process, the melt from an intermittently operated hearth passes to a heated settling chamber and flows therefrom through a plurality of narrow orifices.  In an example, a product suitable for the manufacture of fine paper and paper for photographic purposes is obtained having a granular size in which 50 per cent is smaller than 0,75m , 20 per cent smaller than 1,5m , 15 per cent smaller than 3m  and 15 per cent larger than 3m .

Title: A method of producing an improved glass yarn
Inventor: MENNERICH FRED AUGUST
IPC: D02G3/18
Filed: 1965-08-24
Abstract: In the production of fibrous glass yarn and as the freshly drawn continuous glass filaments are gathered into a strand, a lubricating and binding size having a liquid e.g. water carrier as the major component is applied thereto.  The sized strand is wound on a package tube from which the package is detached and stored under controlled conditions which restrict, and prevent premature, evaporation of the liquid.  The strand is then spun e.g. on a ring-spinning frame, into yarn under controlled atmospheric conditions which permit evaporation of the liquid so that the size sets to bond the filaments together as they are finally twisted.  The restrictive conditions may be maintained, as by means of controlled water sprays, in conveying and storage chambers Figs. 2 and 3 (not shown) through which the packages pass successively; alternatively, each package may be stored within a sealed, plastic, cover, wrapping or envelope or in a container within which a high humidity is established by a slight evaporation of the liquid carrier.

Title: Process for the purification of crude benzene
IPC: C07C7/163
Filed: 1954-12-16
Abstract: In purifying benzene by treating it with hydrogen at elevated temperature and pressure in the presence of catalysts which accelerate action of the hydrogen on impurities in the benzene, the hydrogen gas also contains polymerizable impurities, such gas and the crude benzene being treated in the vapour phase, without evaporation of benzene, to convert polymerizable substances in the benzene and in the gas to benzene-soluble substances of higher boiling point which remain on subsequently evaporating off the benzene and its homologues.  The gases are exemplified by coke oven gas, town gas, gas obtained by low-temperature carbonization, producer gas, cracking gas, carburetted water gas, residual gases from hydrogenations or hydrocarbon syntheses.  The catalysts are exemplified by oxides and sulphides of elements of Groups V, VI and VIII of the Periodic Classification, e.g. mixtures of the oxides or sulphides of molybdenum or tungsten with oxides or sulphides of cobalt or nickel, the catalyst being preferably on a carrier such as activated alumina or a zinc, magnesium or thorium oxide or silicate.  A temperature of 200 DEG  C. and a pressure of 30-100, preferably 50, atmospheres may be employed.

[Class 145 (ii).] In a frame saw the feed rate, the inclination of the saws, and the height of the pressure rollers are adjusted to suit varying thicknesses of timber by power supplied from a continuously rotating shaft 2 through manually operable couplings. To adjust the feed speed, friction discs 4, 5 are raised or lowered by a hand-lever into contact with the disc 6. This, through the train 11 .. 17, moves the disc 19 radially across the driven disc 21 and so varies the speed of the rollers 29 driven through the chain 25 and gearing 27, 28. The saw blade inclination is simultaneously varied by the eccentric arm 30 on shaft 14 moving the saw heads against the action of springs 35. The pressure rollers 36 are raised or lowered by the handles 53 bringing discs 39, 40 into contact with discs 37 or 38. These then move the supporting frames 50 by the racks 47, 48, and pinions 45, 46.

Title: Arrangement for converting direct current into alternating current by means of electric vacuum valves
IPC: H02M7/51
Filed: 1928-12-13
Abstract: 302,362. Maschinenfabrik Oerlikon. Dec. 16, 1927, [Convention date]. Vacuum or low-pressure apparatus, arrangements of.-An arrangement for converting D.C. into A.C. comprises a pair of vacuum valves V<1>, V<2>, the anodes A<1>, A<2> of which are connected to opposite ends of the primary winding P of a transformer T. The source of D.C., such as a battery Q, is connected to the mid-point of the winding P and, through a choke D, to the cathodes K<1>, K<2> of the valves. An alternating flux for generating an alternating current in the secondary winding S of the transformer T is produced by periodic ionization of the two valves by producing a spark at the ionization anodes K<1>, K<2> alternately. Current from the source Q is thus caused to flow alternately in the two halves of the primary winding P, the circuit of each valve being interrupted by the back e.m.f between the cathode and anode set up when the other valve is started, the choke D being provided to ensure that the anode potential of the valve commencing to conduct is immediately impressed upon the cathode of the valve to be interrupted. The ionizing sparks may be produced in a manner similar to that employed in motor-car ignition systems, the phase of the derived A.C. being adjusted by advancing or retarding the ignition. Synchronous motors fed from an existing A.C. system may be employed for driving the contact breakers when the arrangement is required to work in parallel with that system. Inductances and capacities may be included in the circuits of the valves to modify the rate of increase and decrease of the currents in the valve circuits.

Abstract: In a process for making asymmetrical polyazo dyes a diazoamino-diazo compound of formula <FORM:0908202/IV (b)/1> where R1 and R2 are benzenic residues, R3N is the residue of a primary or secondary amine of the aliphatic, cycloaliphatic or aromatic series, and X is a single bond or a bridge member, is coupled with an azo component and the diazoamino group is split in the resulting product and coupled with a coupling component different from the first coupling component.  R1 and R2 may carry substituents such as halogen, nitro, alkyl, alkoxy, sulphone, sulphonamide, sulphonic acid or carboxylic acid groups.  Bridge members indicated for X are -N=N-, -NHCONH-, -NHCO, -SO2-, -CO-or -CH=CH-.  Examples of indicated amines are sarcosine, diethanolamine, 5-sulpho-2-alkylaminobenzoic acids and phenyl-glycine-carboxylic acid.  Indicated coupling components are pyrazolones and their sulphonic acids, acetoacetic anilides, arylides of 2,3-hydroxynaphthoic acids, naphthols, naphthylamines, aminonaphthols and sulphonic acids of the last three types of compounds.  The starting diazo amino compounds are made by coupling appropriate tetrazo compounds and amines, tetrazo compounds with low coupling energies being preferably coupled with aliphatic amines. The starting compounds may also be made by splitting on one side bis-diazoamido compounds obtained by treating appropriate tetrazo components in two steps with different amines.  The latter process is of advantage when special demands are made on the stability of the remaining diazoamino group.  Examples are provided of the preparation of the dyes and their use in colouring cotton and wool in a variety of colours.

Title: Method for producing l-glutamic acid from racemic glutamic acid by use of a micro-organism
IPC: C12P17/10
Filed: 1959-11-03
Abstract: L-glutamic acid is prepared from racemic glutamic acid by subjecting an aqueous solution of the latter to the action of Pseudomonas cruciviae, a mutant thereof, or the enzyme thereof, whereby the L-glutamic acid is converted into L-2-pyrrolidone-5-carboxylic acid, separating this from the residual D-glutamic acid, and hydrolysing to yield L-glutamic acid.  The D-glutamic acid may be racemised and the process repeated.  The separation of L-pyrrolidonecarboxylic acid from D-glutamic acid may be accomplished by precipitating the latter as its zinc salt and filtering, or by using an ion-exchanger which absorbs glutamic acid but not pyrrolidone-carboxylic acid.  The micro-organism may be used as a proliferated culture medium, as separated cells or as the cell homogenates.  The enzyme of P. cruciviae is prepared by treating lyophilised cells of the organism with supersonic vibration in a phosphate buffer solution, centrifuging, heating the centrifugate, adding saturated ammonium sulphate solution, discarding the precipitate, adding solid ammonium sulphate, and centrifuging and lyophilising the precipitate. Specification 884,415 is referred to.
