Title: Improvements in the manufacture and production of vat dyestuffs of the anthraquinoneacridone series
IPC: C09B5/34
Filed: 1929-10-23
Abstract: Halogenated anthraquinone benzacridones.-Anthraquinone benzacridones or their halogen derivatives are treated with agents capable of replacing oxygen by halogen, preferably in an inert organic solvent or diluent, and the products halogenated with an agent customarily employed for replacing hydrogen by halogen and in presence of an organic solvent or diluent. Phosphorus pentachloride or thionyl chloride may be used for the first stage, and the soluble compounds thus formed are converted by the subsequent halogenation into dyestuffs or intermediate products which latter, by treatment with agents splitting off halogen, such as phenol or sulphur dioxide, are also converted to dyestuffs.  In examples (1) trichloranthraquinone-1,2-benzacridone (prepared by halogenating the benzacridone in nitrobenzene with sulphuryl chloride in the presence of chloriodine) is treated with phosphorus pentachloride in trichlorbenzene and then with chlorine to give a red-violet dyestuff; phosphorus trichloride or thionyl chloride may also be used in the first stage, but in the latter case the final product is treated in o-dichlorbenzene with phenol to give a pink-dyeing benzacridone; when the above treatment with phosphorus pentachloride is followed by a treatment with thionyl chloride the product is also further treated with phenol as above: (2) anthraquinone benzacridone (example of Specification 12653/09, [Class 2 (iii), Dyes &c.], is treated with phosphorus pentachloride in trichlorbenzene and then chlorinated; the product dyes bluish-red shades; when treated with phosphorus pentachloride in nitrobenzene followed by bromination a product dyeing yellow-red shades is obtained.  Specification 295,770, [Class 2 (iii), Dyes &c.], also is referred to.  Reference has been directed by the Comptroller to Specification 295,770.

Title: Improvements in processes of producing titanium nitrogen compounds
IPC: C01B21/076
Filed: 1921-12-07
Abstract: Titanium-nitrogen compounds are produced by heating a mixture of ilmenite, carbon, and an alkali-metal compound containing oxygen but not containing sulphur, in presence of nitrogen or gaseous mixtures containing the same, the temperature being slightly below the melting point of the mass.  The carbon may be supplied as soot, coke, or a compound containing carbon, such as crude oil, and these materials may be supplemented, or even supplanted, by gaseous mixtures containing hydrocarbons, such as natural gas.  In one example, 100 parts of finely ground ilmenite, 5 parts of anhydrous soda ash, and 10 parts of pitch are briquetted and heated under slight pressure for six hours in presence of natural gas containing 20 per cent by volume of nitrogen.  The temperature may be at first between 1100-1200 DEG C., but is finally maintained at 1000-1100 DEG  C., to avoid melting the iron.  The product is allowed to cool in an atmosphere of neutral gas, and the iron dissolved out with warm dilute sulphuric acid. Another example illustrates the use of crude oil tar as the reducing agent, and sodium silicate and soda-ash as the alkali-metal compounds.  The titanium nitride or cyanonitride obtained may be used for the preparation of ammonia, or directly as a fertilizer.ALSO:In a process for the production of titanium-nitrogen compounds from ilmenite, the iron is reduced to the metallic state and is dissolved out from the final product with warm dilute sulphuric acid.  The titanium-nitrogen compounds obtained may be used as a source of titanium oxide or titanium salts.

Title: Improvements in and relating to electric remote metering systems
IPC: G08C19/00
Filed: 1932-11-21
Abstract: 394,232. Electric signalling systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitats- Ges.; 2, Friedrich Karl-Ufer, Berlin.) Nov. 21, 1932, No. 32870. Convention date, Nov. 19, 1931. [Class 40 (i).] For indicating or integrating the sum or or difference of the quantities measured by a plurality of measuring instruments, the instruments control impulse transmitters connected in series in a line circuit each transmitter being adapted to transmit impulses at a frequency dependent on the algebraic sum or difference of the value measured by the instrument and the values measured by instruments connected in series therewith but more remote from the indicating station. The Figure shows the equipment associated with a single instrument. Instruments more remote from the indicating station are connected in series in the line wires 10 and the frequency and polarity of the impulses incoming to the station shown in the Figure determines the operation of one or other of the ratchet wheels 16, 17 to rotate the wheel 18 of the differential gear 19 in one or other direction at a speed which is indicative of the sum or difference of the values measured by the instruments on the line wires 10. The local instrument drives the second wheel 20 of the differential gear through gearing 24', 21 and the planet wheel 25 controls an interrupter 26 which transmits impulses over line wires 11 to the next series station or the indicating station at a modified rate dependent upon the speed of the wheel 20. The planet wheel 25 also controls a worm 28 the grooves of which control a switch 29 which reverses the polarity of the outgoing impulses in accordance with the direction of rotation of the planet wheel and thus the relative rotations of the wheels 18, 20. In a modification the differential gear is dispensed with, the incoming impulses operating a commutator having brushes which are rotated by the local instrument. In this arrangement the commutator at the instrument located at the remote end of the line is driven at a constant speed which may be chosen so that the transmitted impulses are of single polarity independent of the direction of rotation of the measuring instrument. The stepby-step movements produced by the impulses may be converted into uniform movement for operation of the interrupters by a coupling comprising an accumulator spring controlled by an eddy-current brake disc.

Title: Improvements in and relating to operating devices for the closing and fastening mechanism of sliding roofs for vehicles
IPC: E05B83/00
Filed: 1959-09-29
Abstract: 880,351. Releasable fastenings. WEBASTOWERK G.m.b.H. Sept. 29, 1959 [Oct. 15, 1958], No. 33074/59. Class 44. An operating device for the closure and fastening mechanism of a sliding roof of a vehicle comprises an operating handle 10 consisting of a transverse handle part 11 and a handle stem 12, the handle being adapted to be swung out of a handle recess 2 by turning through 90 degrees and then rotated about the stem axis to actuate the roof - fastening mechanism, a locking device 8 preventing the folding-in of the operating handle while the roof-fastening mechanism is unfastened. The handle is pivotally attached to a lug by means of a spindle 5 the lug being welded to a spindle 4 which is rotatable in a bearing member 7. The spindle 4 is welded to a lever 6 which operates the fastening mechanism. The handle pivots through 90 degrees about the spindle 5 and it has a spring loaded catch 13 which engages a notch 16 in the lug in its operative position and a similar notch 15 in its inoperative position. When the handle is turned through 180 degrees to operate the fastening mechanism the end 17 of its stem abuts against the locking device 8 and prevents the handle being folded to its inoperative position. The locking device 8, as shown, is a part-ring carried by the member 7, the arcuate extent of the ring being such that the handle can only be folded when the fastening device is in its fastening position. Cheeks 18 on the handle stem prevent the handle being turned through 180 degrees to operate the fastening mechanism unless it has been moved through 90 degrees to its operating position. In a modification the locking device can consist of a pin or a sheet metal part, the folding of the handle when a pin is used being prevented only when the handle has been turned through its full 180 degrees to operate the fastening mechanism.

Title: A process of purifying juice
IPC: C13B20/06
Filed: 1948-12-23
Abstract: In the process of purifying juices or extracts, particularly sugar juices from beets, by the addition of lime to precipitate the colloids and then treating with carbon dioxide to precipitate the excess lime in the presence of the precipitated colloids, the alkalinity of the juice during carbonation is adjusted to a low value to ensure a negative charge on the precipitated colloids whereby they can aggregate with the positively-charged calcium carbonate, and the aggregates so formed are enlarged and stabilized against subsequent increase in the alkalinity by adding the scum juice to raw juice, the mixture being then pre-defecated, defecated and carbonated in the usual way.  The juice is first treated with a small amount of milk of lime so as to increase the alkalinity above the optimum for the flocculation of the colloids and then, after heating, dry unslaked lime is added to increase the alkalinity further.  The liquid is then first carbonated to approximately the optimum alkalinity, and subsequently a part is further carbonated to reduce the alkalinity considerably below the optimum, this part being mixed with a quantity of raw juice. The remainder of the carbonated juice is passed to the filters.
