Title: Manufacture and use of compounds of the anthraquinone series
IPC: C07C50/34
Filed: 1929-11-15
Abstract: Anthraquinone dyes; cellulose esters and ethers, dyeing.-Hydroxy anthraquinone derivatives are made by replacing at least part of the halogen in halogenated 1 : 5-dioxyanthraquinones by hydroxyl using sulphuric acid, oleum or an alkali, e.g. calcium hydroxide in presence of water and copper or a copper compound.  The new products containing halogen or their leuco compounds are converted into colouring matters by amidation: the process of Specification 310,784, [Class 2 (iii), Dyes &c.], may be used.  Oxidation of the amidated leuco compounds may be effected by adding an aromatic nitro compound to the amidating liquor (cf. Specification 316,989, [Class 2 (iii), Dyes &c.].  Other colouring matters are obtained by etherifying either the hydroxylated compounds obtained by the partial replacement of halogen in halogenated anthrarufins by hydroxyl groups, or the amidated halogen containing products derived therefrom.  In addition, colouring matters are obtained by etherifying the hydroxylated halogen containing compounds and then amidating.  The above amidated and/or etherified colouring matters are used for dyeing cellulose esters and ethers.  They may be applied in the reduced state (cf. Specification 341,408), or in solution, in aqueous suspension or in colloidal form and may be converted into concentrated or other preparations.  Preparations intended for vatting may contain reducing agents or alkali salts of hydroxy cyclic compounds (see Specification 262,506, [Class 15 (ii), Dyeing, Processes &c. for].  As dispersing agents those described in Specifications 219,349, 224,925, 242,393, 273,819, 273,820, 322,737 and 323,788, [all in Class 15 (ii), Dyeing, Processes &c. for], are mentioned used either alone or in conjunction with the solvents of Specifications 242,711 and 269,960, [both in Class 15 (ii), Dyeing, Processes &c. for].  In examples: (1) anthrarufin is p  treated with sulphuryl chloride in nitrobenzene and the isolated reaction product is heated with sulphuric acid containing boric acid; 6-chloro-1 : 4 : 5-trioxyanthraquinone is obtained; (2) the product of (1) is reduced with hydrosulphite, the leuco compound refluxed with alcoholic methylamine and the product oxidized with sodium perborate; it dyes cellulose acetate in greenish-blue shades; (3) the product of (1) is refluxed with nitrobenzene, p-toluenesulphonic acid methyl ester and sodium carbonate; the methylated product dyes cellulose acetate in yellowish shades from an aqueous dispersion.

Title: Improvements in and relating to the granulation of molten material
Inventor: HOY HERBERT RAYMOND
IPC: F23J1/08
Filed: 1958-10-31
Abstract: 939,071. Granulating molten material. C.U.R.A. PATENTS Ltd. Oct. 26, 1959 [Oct. 31, 1958], No. 35107/58. Class 82. Apparatus for granulating molten material consists of a trough carrying a stream of coolant, into which the material is discharged from above. The trough is longitudinally retractable in one direction and is provided with means for dislodging adherent solidified material said means being spaced from the material discharge point in the direction of retraction of the trough, retraction of the trough causing relative longitudinal movement between it and the dislodging means. The apparatus may be equipped with two similar but independent troughs so that when one is in its operative position the other is retracted and may be completely withdrawn, e.g. for repair. For removing solidified material adhering to the molten material outlet there may be provided a torch for softening the material and a member horizontally movable close below the outlet, there also being provided water cooled means for scraping the said member. Conditions in the trough may be observed through a window either visually or remotely by means of a television camera. The latter, or a photo-electric device, may be arranged to operate the removing means at the material outlet and retract the trough automatically when necessary. In one form of apparatus, Fig. 1, the trough 1 is connected to inlet pipe 2 and outlet pipe 3, and is retractable by means of a rod 11. Molten material is discharged into the coolant from outlet 5, and any which adheres to the trough on solidification is dislodged by fixed vertical vanes 17 and side members 18 (Fig. 2) when the trough is retracted. Solid material adhering to the lip 6 of outlet 5 is softened by torch 28 and removed by horizontally movable bar 21 which is equipped with water-cooled scrapers 25 and 26. Additional coolant is added at 16 to increase turbulence and break up the granulated material.

Patent GB-453417-A (GB)
Title: Candy product and process
IPC: A23G3/34
Filed: 1934-12-07
Abstract: A powder is made by drying and reducing a mass of fudge or fondant, the powder being capable of reconstruction into fudge by simple melting with water and heat and thereafter cooling the mass without a creaming or graining step.  The original fudge may be without the usual fat content, the addition of fat being effected during the reconstitution.  The fudge is made, for example, of unsweetened evaporated milk, corn syrup, granulated sugar, fat (butter, coconut butter or hydrogenated fat), salt and a flavouring such as chocolate, cocoa or vanilla.  Examples of proportions are referred to.  The ingredients are mixed together and cooked at 235-255 DEG  F., with constant agitation, and then poured into a beater, having a cold-water jacket, in which the temperature is reduced to 90-120 DEG F., before the agitator is started.  When the mass is properly creamed and grained it is warmed to 125-160 DEG  F., and is spread on pans to set. Alternatively, the ingredients are cooked to 235-255 DEG F., and then cooled to 150-200 DEG  F.  The mass is then creamed, by stirring in a small quantity of fondant, spread in layers and allowed to set.  This fondant is composed of 5-20 parts by weight of corn syrup to 75 parts of sugar and 16 parts of water, which are cooked, cooled and creamed by stirring.  The fudge may be dried by subjecting to heat in an exhaust chamber, and may be powdered by passing the dried fudge through rollers, scraping it off, and rolling again until sufficiently reduced.  Residual lumps are removed by screening.  If the powder is reconstituted with an excess of water, the substance may be used for icing cakes.  To make caramel candy, a small excess of water is used in the reconstitution, and the mixture is cooked to the "medium ball" stage, i.e., when it will form medium balls when a small quantity is dropped into cold water.  It is then spread out to cool and set.  If nut caramels are required, chopped nuts are stirred into the mixture before spreading out.  It is suggested that in the making of fudge, very fine sugar crystals are separated by a film of uncrystallizable substances either produced in the batch itself or added in predetermined amounts.  This film may consist of added invert sugar, or invert sugar produced in the batch by adding acid or acid salts, such as citric, tartaric or acetic acid, or cream of tartar to plain sugar and cooking.  The invert sugar may be formed by cooking sugar and water for long periods without acid additions, or slightly caramelizing the sugar by higher heating. Other colloidal and non-crystallizable materials, such as corn syrup or glucose, honey, gum arabic dextrine, tragacanth, gelatine, may be used.

Abstract: 394,883. Television receivers. TELEFUNKEN GES. FUR DRAHTLOSE TELECRAPHIE, 12, Hallesches Ufer, Berlin. Dec. 12, 1932, No. 35208. Convention date, Dec. 12, 1931. [Class 40 (iii).] Scanning in a cathode-ray tube 1 is controlled by a circuit in which a condenser 22 discharges at the end of each scanning-line in response to the reception of a synchronizing signal and is prevented from accidental response to powerful picture signals until the end of the line is reached. Electrostatic deflecting-plates 5, 6, which move the cathode ray 4 along each scanning-line, are in parallel with the condenser 22 which is charged from the anode-voltage source 13 for the tube through a very high resistance 21 so that the circuit operates on the rectilinear part of the charging curve. The condenser is discharged by a thyratron valve 23 when made conductive by a sufficient bias applied to its grid 25 by rectified signals across a resistance 26. Additional and opposing bias, sufficient to prevent the thyratron becoming conductive, normally is applied by the anode current from a valve 28 through a resistance 27. A bias, sufficient to stop the anode current, is applied-to the grid 29 of the valve when a straight wire 18 beside the picture screen 2 is struck by the cathode ray at the end of each scanning-line. The movement of the cathode ray from line to line is controlled by a condenser (not shown), which receives a fixed increase in charge each time the condenser 22 discharges. The condenser is discharged at the end of each picture by a second thyratron or the like actuated by a special signal, which is separated from the other signals.

Abstract: 306,117. Allmõnna. Svenska Elektriska Aktiebolaget. Feb. 17, 1928, [Convention date]. Current transformer. - To enable the transformation ratio of current transformers to be accurately adjusted, the core is divided so as to form two parallel paths 2, 3 for the flux produced by current in the primary 1, and the secondary comprises a number of windings arranged one on each core part and connected in parallel so that the effect of each secondary turn is reduced in proportion to the number of paths provided for the flux as compared with a transformer in which the secondary turns embrace the total flux. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a transformer in which the secondary which is mainly composed of turns 4 embracing both core parts has one or more turns 5 embracing one part only so as to be affected by only a fraction of the total flux. In an alternative form, the primary consists of a number of turns placed together with the main part of the secondary on one limb of a divided rectangular core, the turn or turns that embrace only a part of the flux being wound on the opposite limb of the core. This subject-matter does not appear in the Specification as accepted.

Title: Error Correction Circuits for Analog Signal Processing.
Inventor: SCHMID HERMANN
IPC: H03M1/00
Filed: 1967-08-02
Abstract: 1,190,631. Analogue-to-digital converters. GENERAL ELECTRIC CO. 2 Aug., 1967 [21 Oct., 1966], No. 35498/67. Heading G4H. An error correcting circuit for an analogue-todigital converter comprises an error storage register into which the lowest 5 bits are entered from the 11-bit register of the converter, a test source which produces a zero number in the test register when the converter is accurate, a digital-to-analogue converter responsive to the error storage register to generate a correcting signal which is applied to the converter, the test source being connected to the converter input alternately with the unknown analogue signals by a multiplexing circuit. The multiplexing circuit comprises switches 10-14, e.g. fieldeffect transistors, connecting the various inputs to a pulse length generator 30. The output of the generator 30 is differentiated to produce a sharp read-out pulse at the end of the pulse length to transfer the value then standing in a counter 20 (which counts clock pulses fo from the beginning of the cycle) to the corresponding register 21, 22, 23 &c., or error store 40, selected by the closing of appropriate switches 26, 27, 28. The input signal is biased by the negative reference voltage - VR which is set at half the full-scale value. The value - V R  therefore gives a zero reading and +V R  a full-scale reading. The sign of the input signal is shown by the highest digit (2<SP>10</SP>). This digit and the five lowest digits are entered into the error store 40. When the test signal is applied the error register should produce five 0's. If any of these digits is not zero a corresponding correction voltage is applied to the operational amplifier of the pulselength generator. The value in the error storage register is displayed on lamps.

[Class 40 (v)] In a receiver employing a tight back-coupling self oscillation is prevented by causing the receiving valve to oscillate at a frequency higher than that at which the back-coupling is effected. Fig. 1 shows a frequency changer 1 in which the intermediate frequency circuit 7, 8 is back-coupled and the local oscillator circuit 4, 5 serves to prevent self oscillation at the intermediate frequency. Radiation of the local oscillation is prevented by the balancing condenser 20. In a modification, Fig. 2 (not shown), a similar double valve is employed and the grid 3 is associated with an oscillating circuit and a circuit tuned to the signal. Fig. 3 shows an arrangement in which a pair of valves 22, 23 oscillate in parallel at the frequency of circuit 27, 28. The signal is applied to the valves in push-pull from an aerial 41 while the intermediate frequency circuit 24, 25 is backcoupled by condensers 31, 32. In a modification, Fig. 4 (not shown), the signal is applied to the pair of valves in phase and the local oscillation is in push-pull and chokes are provided to keep the impedance of the circuit of the anodes high at this frequency. The amount of backcoupling at the intermediate frequency may be adjustable to vary selectivity, the consequent volume variation being prevented by the automatic volume control.
