Title: Process for the manufacture of new vat dyestuffs of the anthraquinone series
IPC: C09B1/34
Filed: 1929-01-12
Abstract: 327,967. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Jan. 12, 1929. Anthraquinone-acridones are made by introducing one or more halogen atoms into the benzene ring of a 4-amino-3-halogenanthraquinone-1 :2- acridone by halogenation in the customary manner or by treatment of 1-amino-2-4-dihalogenanthraquinones with halogen anthranilic acids or salts thereof, in presence of an acid fixing agent and a catalytically active substance such as cupric chloride, if necessary in a suitable solvent, and condensing the resulting product with ring closure by treatment with an acid condensing agent, such as concentrated sulphuric acid or chlorsulphonic acid. In examples (1) 1-amino-2:4-dibromoanthraquinone is condensed with potassium-2-amino-3 :5-dichlorobenzoate, the product boiled with dilute hydrochloric acid, and the ring closed with concentrated sulphuric acid. The product dyes cotton bluish-green shades; (2) 4 - amino - 3 - bromoanthraquinonel: 2-acridine is chlorinated by passing chlorine through the solution. The product dyes cotton bluish-green shades. The aminohalogenanthraquinoneacridones can be obtained from the corresponding dihalogenaminoanthraquinones by treatment with anthranilic acid and subsequent closing of the ring.

Abstract: 269,637. Estaugh, W. Jan. 15, 1926. Addition to 233,124. Code telegrahy.-The system of the parent Specification is modified by the permanent connection to the inner conductor at the transmitting station of an earthed battery of higher potential than the charging battery at the receiving station, the signals being produced by varying the charging potential at the transmitting station. In one arrangement, Fig. 1, the inner conductor a is earthed at the transmitting station thiough opposed signalling batteries k, l in series with a charging battery j. The effective potentials of the batteries j, k, and l, as indicated by voltmeters p, q, and r, are adjusted on potentiometers o, n, and in respectively, those of the batteries k and l being made equal, and signalling is effected by short-circuiting the batteries and l by keys s and t respectively. Alternatively the operation of a key may introduce a corresponding battery k or l into the circuit. The receiving instrument u is connected across the inner and outer conductors a, b either directly, as shown, or through an amplifying valve of which the input circuit includes a. resistance or transformer connection across the conductors.

Abstract: 283,861. Zweigle, G. Jan. 17, 1927, [Convention date]. Fibres, sorting; fibres, testing.-In grading a sample of cotton fibres to determine the proportion of the different lengths present therein, a quantity of determined weight is subdivided into individual groups of the same staple and these groups are weighed so that the percentages of weights of the individual groups serve as comparison values. The apparatus used comprises upper and lower needle fields A, B composed of yokes c, d carrying needles. A fibre tuft F, Fig. 2. is dabbed into the lower field A. The fibres projecting beyond the front of the field are transferred by tongs to the field B, a supporting bar s is shifted backwards to allow the first yoke c to be dropped and the process of transfer continued, the same being repeated until all the fibres are transferred to the field B when they will be arranged in length order. The field B is then swung over into the position shown in Fig. 6 and each group of projecting fibres, obtained by the removal of a pair of yokes comprising an upper and a lower yoke, is separated and weighed. A scale on the bar s gives the staple length of each group.

Title: Improvements in and relating to the treatment of coffee beans
IPC: A23F5/16
Filed: 1930-01-17
Abstract: Coffee beans are heated with moisture under a pressure of 1-3 atmospheres to decompose the constituents causing unpleasant taste and smell.  The chief constituent producing unpleasant taste and smell is chlorogenic acid (caffeo-tannic acid) and during the process, this is broken down into caffeic and kinic (quinic) acids. The hydrolytic action of the moisture may be assisted by the presence of mineral acids, and alkali metal hydroxides or carbonates.  When these are used, the product is neutralized.

[Class 51 (ii).] In a process for firing pressed ceramic material and recovering oil therefrom, the material is heated in a chamber built into a furnace and separated from the remainder of it, until the oil in the material is evaporated, the oil being led off for utilization, any final firing of the material that is required then being effected in a subsequent heating stage of the furnace. In the tunnel kiln shown, the oil evaporation zone or chamber is formed bv the walls o and doors d, e which can be raised and are counterbalanced. An excess pressure is produced in the chamber by blowing air into it through pipes l, m to prevent entry of combustion gases. The mixture of oil vapour and air is drawn off through a pipe n, and may be utilized, together with other fuel, to supply the burners f for heating the furnace. The wagons 1 .. 5 are in the water evaporation zone, 6 .. 9 in the oil evaporation zone, 10 .. 13 in the heating zone, and 14 .. 20 in the cooling zone. If the heating zone is not necessary, the burners may be disposed laterally of the wagons 8, 9. Air warmed in the cooling zone may be used to supply the conduits l, m, and for combustion. In a single furnace, the material is directly heated to drive off the water, indirectly heated to evaporate the oil, and finally directly or indirectly heated, or allowed to cool.

Abstract: 563,491. Electric control systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and FORMBY, W. L. Feb. 10, 1943, No. 2206. [Class 38 (iv)] [Also in Groups XXXVI and XXXVII] A relay particularly suitable in combination with similar relays for battery charging systems automatic voltage regulation or voltage indicating, has two windings ab and de connected in parallel or series and acting in opposition, one winding being associated with a non-linear resistance such as NLR2, the resistance of which varies with applied voltage while the temperature remains the same. By this arrangement one winding will overpower the other at certain voltages, but will itself be overpowered at other voltages. Fig. 2 shows a, system for battery charging, contacts c2 being operated to provide a high voltage charging current when the voltage of the battery falls to 48 volts and a low voltage charging current when the voltage of the battery rises to 54. The contacts c2 are operated by relay C a resistance R3 of which is normally short-circuited by contact b1 of relay B, the non-linear resistance NLR2 of which is short-circuited at c1 by operation of relay C. With parts in the position shown, a battery voltage between 48 and 54 will operate relay e over contact b1. Relay C will operate c2 for high charging and will short-circuit NLR2 so that relay B operates and contacts b1 open. Relay C remains operated, since although winding de is opposed by winding ab it overpowers it. When voltage reaches 52, the relative strength of ab has increased owing to non-linear resistance NLR3 so that the relay C releases, and the low rate of charging is set up, till the voltage 48 is reached when the relay B, under the differential action of its windings releases, whereupon C operates. The cycle continues similarly. The material used for the non-linear resistance may be silicon carbide together with carbon and for tungsten and molybdenum, agglomerated under pressure and baked, and it may take the form of a disc. Selenium or copper oxide may also be used and sensitivity may be further increased by having a resistance with a negative characteristic in circuit with one winding and one with a positive characteristic in circuit with the other winding.
