Title: Improved process for dyeing chrome leather with basic dyestuffs
IPC: D06P3/32
Filed: 1929-01-21
Abstract: 304,608. Oranienburger Chemische Fabrik Akt.-Ges. Jan. 19, 1928, [Con. vention date]. Sulphonic acids, which are mordants for basic dyes upon chrome leather, are obtained by the action of strong condensing and sulphonating agents upon fats, fatty acids, natural resins or fat-like substances, the high boiling distillation products of petroleum, brown coal tar, or other bituminous body or upon mixtures of these substances with compounds capable of being condensed therewith, under the conditions of the sulphonation. The products may be obtained, for example, by the action of a sulphuric acid halogenhydrin upon a fat or a mixture of a fat with an aromatic hydrocarbon, an alcohol, a carboxylic acid or an acid chloride or anhydride (c.f. Specifications 275,267 and 288,126) or upon a mineral oil alone or mixed with an alcohol, thioalcohol, phenol, hydrophenol, carboxylic acid or an acid anhydride or chloride. The halogen containing sulphonic acids obtained by using a halogen transferring substance, such as manganese dioxide, in the sulphonation (c.f. Specification 289,841) and the ketone sulphonic acids or their salts obtainable by sulphonation of the products of condensation of the chlorides of higher fatty acids with aromatic hydrocarbons in the presence of aluminium chloride (cf. Specification 269,917, [Class 15 (i), Dyeing, Processes &c. for]), have similar mordanting properties. In examples, the following mixtures are treated with chlorsulphonic acid : (1) wool-fat and arachis oil fatty acid; (2) naphthalene and the fatty acids of arachis oil and soya oil; (3) castor oil and acetic anhyride; (4) the product obtained by condensing benzene with oleic acid chloride in the presence of aluminium chloride ; (5) a mineral oil and iso-propylalcohol. The sulpho acids are usually neutralized, and may be bleached by means of sodium hypochlorite. Besides mordanting the fibre, the products exert a cleaning, wetting and oiling action. Mixtures of halogen-sulphonic acid with concentrated or fuming sulphuric acid and/or a dehydrating agent, e.g. phosphorus oxychloride, pentoxide, or trichloride or other inorganic acid chloride, are also mentioned as sulphonating agents. Specifications 308,280 and 313.861 also are referred to.

Abstract: 547,292. Wet-separating. AMERICAN CYANAMID CO. Feb. 17, 1941. No. 2149. Convention date, March 30, 1940. [Class 82 (ii)] [Also in Group IV] Concentration or froth flotation processes for separating acidic ore materials, such as silica, from non-metallic ores such as phosphates, calcite, fluorspar &c. are carried out in the presence of a collector for such acidic material chosen from the group consisting of the reaction products of polyalkylene polyamines with higher fatty acids or esters and salts thereof. The different amino groups are separated from one another by a hydrocarbon radical containing 2 to 12 carbon atoms, a fatty acid radical containing at least 10 carbon atoms, salts of the polyamine compound or mixtures of polyamine compounds with or without their salts being attached to at least one of the nitrogen atoms. The collector may also be a reagent from the group consisting of mixed polyethylene amines with coconut oil fatty acids or esters of such acids and acid salts of such products. Examples of such amines are diethylene tetramine, dipropylene triamine, dibutylene triamine or tetraethylene pentamine, and the fatty acids are those having at least nine carbon atoms such as lauric, palmitic, stearic, oleic, ricinoleic, capric or myristic acids or mixtures of such acids such as those obtained from vegetable or animals oils or their glycerides such as those in coconut oil, palm oil, corn oil, olive oil, peanut oil, fish oils &c. The reagents may generally be prepared by heating a fatty acid or a glyceride with a polyalkylene polyamine at a temperature of 130- 2150‹C. until the reaction is complete.

Title: Improvements in or relating to high-frequency electronic devices in which an electromagnetic field is caused to interact with an electron stream
IPC: H01J25/12
Filed: 1944-02-11
Abstract: 623,985. Velocity - modulated tubes. WESTERN ELECTRIC CO., Inc. Feb. 11, 1944, No. 2610. Convention date, March 7, 1941. [Class 39 (i)] In a velocity-modulation discharge tube the spacing between the grids 1, 2 of the buncher resonator 5, the ratio between the electron transmitting and electron obstructing areas of the grids 1, 2, and the average time rate of flow of the electrons in the beam are so interrelated that the impedance of the beam is made substantially equal to the resonant impedance of the resonator 5. The average time rate of flow of the electrons may be varied by varying the emission or the beam velocity, and the impedance of the beam is defined as the ratio between the peak value of the alternating voltage across the buncher grids 1, 2 considered as the space integral of the field between grids 1, 2, and the resultant current variation at the operating frequency produced in the beam between grids 1, 2. If a plurality of resonators are provided, the impedance of each of them is matched to the beam impedance. To obtain an impedance match in any particular case, the design parameters are adjusted so that the measured resonant impedance of the resonator is made equal to the measured beam impedance, the quantity actually measured in the latter case being the ratio collector voltage to collected microwave current, which bears a known linear relationship to the beam impedance as defined. To assist in the impedance matching procedure, the buncher 5 is excited at different frequencies above and below its resonant frequency and the microwave current in the collector circuit is measured for each frequency so that a resonance curve may be plotted. The width of the resonance curve gives an indication of the degree of impedance matching. The invention may be applied to amplifiers, oscillators, modulators and detectors; e.g. to a multi-stage amplifier, Fig. 4 (not shown), a constant frequency oscillator, Fig. 6 (not shown), or to a variable frequency oscillator, Fig. 7 (not shown), which may be used as a frequency modulation system.' The buncher resonator may be excited electrostatically, Fig. 5A (not shown). Specification 529,771 is referred to. The Specification as open to inspection under Sect. 91 states that the impedances of wave guides may be matched to the beam impedance. In general, the impedance matching need not be exact, but may be to " any desired degree." A construction utilizing a double field grid arrangement is described with reference to Fig. 12 (Cancelled, not shown). This subjectmatter does not appear in the Specification as accepted.

Title: Means for controlling the starting of internal combustion engines
IPC: F02N99/00
Filed: 1931-01-27
Abstract: 362,747. Turning-gear. BRETTELL, F. G., 75, Colmore Row, Birmingham.- (Motor Devices, Inc. ; 540, North Michigan Avenue, Chicago, U.S.A.) Jan. 27, 1931, No. 2613. [Class 7. (v).] The electrical circuits of a starting motor 1 and the ignition of an internal-combustion engine are controlled by a manually operated switch A which when moved in one direction consecutively energizes and de-energizes the circuit of an electromagnet 9 controlling the motor circuit and energizes the ignition circuit 27, and the starting motor is then maintained energized by a circuit closed by a moving part of the starter drive until the engine starts. When moved in the opposite direction, the switch de-energizes the ignition circuit without energizing the electromagnet. As shown, the switch A has stationary contacts 16-18 connected to a battery 22 and to the contacts 31, 32 of the electromagnet 9 ; a contact 19 connected to earth and a contact 21 connected to the ignition circuit 27. Movable contact arms 13, 14 insulated from each other are rotatable on an insulated member 15. On moving the switch from the inoperative position shown in Fig. 3 to the position shown in Fig. 4, the arm 13 bridges the contacts 16, 19, and the arm 14 bridges the contacts 17, 18, so that the electromagnet contacts 31, 32 are connected respectively to the battery 22 and to earth. The armature 10 of the electromagnet 9 then closes the circuit between the battery 22 and the starting motor 1, which is set in rotation. The starter pinion 3 is in screw-threaded engagement with a sleeve driven through a coiled spring, and moves axially into driving position, when its flange 4 engages a contact 5, completing another circuit from the electromagnet contact 32 to earth. In the second position, Fig. 1, of the switch A, the contacts 16, 19 are disconnected and the ignition contact 21 is engaged by the arm 27. On returning the switch to the position shown in Fig. 4, the arm 13 rides over a guard arm 20, so that the contacts 16, 19 are not connected and the motor 1 is switched off as soon as the engine overruns it and returns the pinion 3 automatically along its shaft. In a modification, the contact 18 is shorter and is connected to the terminal 12 of the electromagnet 9 through an additional lead in parallel with the lead 26, Fig. 1; in the second position of the switch A, the contacts 17, 18 are disconnected but current flows to the electromagnet 9 through lead 24, contacts 11, 12, the additional lead, and the lead 26.
