Title: Solutions of diazoamino compounds and coupling components and a process for their preparation
Inventor: PETITCOLAS PIERRE
IPC: D06P1/92
Filed: 1958-07-22
Abstract: A solution directly utilisable for textile printing is prepared by adding an organic solvent miscible with water to an aqueous mixture containing a caustic alkali, an azoic coupling component and a diazoamino compound containing mineral salts resulting from its preparation, allowing the mixture to settle and separating the upper less dense layer which contains the diazoamino compound, the coupling component and the caustic alkali from the lower more dense layer which contains the mineral salts.  The diazoamino compounds may be obtained from diazotised p-toluidine, 1-amino-2-methyl-5 (or -4-)-chlorobenzene, 1-amino-2-methyl-4 : 5- dichlorobenzene, 1-amino-2-methoxy-5- chlorobenzene, 1-amino-2-methyl-5- dimethyl-sulphonamido-benzene, 1-amino-2-methoxy-5-diethylsulphonamido-benzene, 1-amino-2-methoxy-5-nitrobenzene, 4-N-phenylamino-1- aminobenzene and 41-methoxy-4-phenylamino-1-aminobenzene and (as stabilisers), sarcosine, 2-carboxy-phenylglycine, 4 : 6-dichloro-2- carboxy-phenylglycine, 2-hydroxyethylamino- 5-bromo-benzoic acid, 5-sulpho-2-ethylaminobenzoic acid and 5-sulpho-2-isopropylaminobenzoic acid.  Specified coupling components are the arylides of 2 : 3-hydroxynaphthoic acid, 2-hydroxy-3-carboxy carbazole and acetyl acetic acid.  Specified solvents are ethylene-, diethylene-, and propylene-glycols, thiodiglycol, dioxane and the monoethyl, monomethyl or monobutyl ethers of ethylene-or diethylene-glycol.  The solution may also contain a volatile amine such as diethylaminoethanol, di- or tri-ethanolamine and piperidine. In examples, the solutions, thickened with the usual thickeners, are printed on fabrics and the prints developed in neutral or acid steam.

Title: Fuel supply systems
IPC: F02D3/00
Filed: 1975-05-29
Abstract: 1464340 Fuel injection apparatus SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 29 May 1975 [5 July 1974] 23461/75 Heading FIB  A jet of fuel flowing to an intake pipe 1 of a fuelinjection I.C. engine is controlled by a cyclically moving element 44 which allows fuel to pass for a portion of its movement cycle determined by the rate of air-flow through the intake pipe 1 sensed by an auxiliary throttle valve 5. The auxiliary throttle valve 5 is located upstream, and a fuel injection duct 25 downstream, of a main throttle valve 2. The auxiliary throttle valve 5 is adjusted by a vacuum servomotor sensing the depression between the two throttle valves 2, 5 and its motion is transmitted through gearing 51, 52 to a lever 48. A constant speed electric motor 47 is mounted on the lever 48 and rotates the cyclically movable element 44 (i.e. a disc with shaped apertures 45). Fuel from a pump (not shown) is directed along a duct 19a and is sprayed as a jet towards the disc 44 from an orifice 20. The shaped apertures 45 in the disc 44 allow the fuel to pass into injection duct 25 for a time determined by the relative position of the orifice 20 and rotational axis 46 of disc 44, which is adjusted according to the position of auxiliary throttle valve 5, by the gearing mentioned above. The disc 44 may be replaced by a rotating cylinder; also, the motor 47 need not be at the end of lever 48, but may be at its pivot point 49, a pulley system driving the disc 44. The motor 47 may be replaced by a rotary. take-off from the engine, (not shown). Fuel not passing through the apertures 45 is centrifuged off the disc 44 and returned to a tank via an overflow duct (53).

Title: Improvements in or relating to radar display arrangements
Inventor: SHIPWAY ROGER PROWSE
IPC: G01S7/14
Filed: 1950-09-25
Abstract: 690,577. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 22, 1951 [Sept. 25, 1950], No. 23480/50. Class 40 (vii). The invention relates to the presentation on a common display tube of information derived from a plurality of radar systems scanning in azimuth. The radar azimuth scans are preferably synchronized so that they sweep through a sector of interest in turn and are connected to the display during the time they are scanning the sector. According to the invention in such a system the time-base deflecting waves and the video outputs of the radar systems are automatically and sequentially switched to the display under the control of azimuth modulated time-base waves. Where three radar systems are employed, the time-base waveforms from each system A, B and C, modulated in accordance with the sine and cosine of the angle between the instantaneous direction of scan and a reference direction are fed over " Sin " and " Cos " lines as shown to ganged selector switches AS1, BS1, CS1 which select either the sine or the cosine inputs and feed them to rectifiers A6, B6 and C6. The modulation waveform obtained is fed in each case to the grid of the left-hand valve of a trigger circuit having two stable states, the grids of the right-hand valves being maintained at an adjustable potential determined by the bias applied to line GB. The current flow in the trigger circuits changes over from one valve to the other, and later on back again at times in the modulation cycle dependent on the bias and by means of switches AS2, BX2 and CS2 the pulses obtained from either anode during these change-overs may be passed through switches AS, BS and CS to the gate control circuits. The gate control circuits consist of further trigger circuits A8, B8 and C8 having two stable states and relay coils RA/3, RB/3 and RC/3 in the anode circuits of their right-hand valves. When current is flowing through the right-hand valve of one of these circuits the corresponding relay is operated to feed Sine and Cosine time base voltages and video signals over the relay contacts to the display tube. Operation of the gate control circuit is initiated by a pulse over the corresponding switch AS, BS or CS applied through diode D1. At the same time the pulse is applied to the opposite valves of the other control circuits to cut off any signals which may be applied to the display. It is shown that by suitable positioning of switches AS1, BS1, CS1 and AS2, BS2, CS2, and the application of suitable bias over line GB any 120 degrees sector out of a complete rotation may be displayed successively by the three radar systems. If one of the switches AS, BS or CS is opened, one remaining system will give a 120 degrees presentation and the other a 240 degrees presentation.

Title: Method of treating tobacco to increase its volume
IPC: A24B3/18
Filed: 1971-04-19
Abstract: 1,273,942. Puffing tobacco; reducing the nicotine content of tobacco. CREATIVE ENTERPRISES Inc. 19 April, 1971 [9 March, 1970], No. 23504/71. Heading A2C. Catalase is applied to tobacco which is then contacted with hydrogen peroxide the decomposition of which increases the volume of the tobacco. The preferred source of catalase is yeast which may be applied in an initially sufficient quantity or is more preferably applied in a lesser quantity together with a yeast nutrient solution and allowed to multiply on the tobacco. The hydrogen peroxide also bleaches the tobacco and converts some or all of the nicotine in the tobacco into nicotinic acid and other relatively harmless products. This reduction of nicotine may be enhanced by the addition of catalytic amounts of nitric acid. The yeast may be applied to the tobacco in the form of a suspension in a saturated sucrose solution.

Title: An improved system of aerial conductors for transmitting and receiving in connection with wireless telegraphy and telephony
Filed: 1923-09-24
Abstract: 223,713. Bashenoff, V. I., and Plebanski, J. von. Sept. 24, 1923. Directive signalling; aerials. -- Directional transmitting or receiving aerials, particularly for short waves, comprise a number of angularly spaced polygons connected in parallel across inductance or capacity to form a closed oscillatory circuit. As shown in Fig. 1<a>, the mutual capacity between two wires of the polygons may form a part of this circuit. The directive effect may be increased by providing connections a-b, c-d, as shown in Fig. 8, or by the insertion of inductance or capacity as shown, for example, in Fig. 1<b>, to produce a phase displacement between the currents in the various polygons. Preferably, the whole system is rotatably supported on a single mast. Alternatively, the system may be erected in all directions and the grouping controlled by a switch, as shown in Fig. 7. The aerial system may be excited directly in any known manner or through a closed oscillatory circuit as is usual with open aerials. Duplex working is possible by erecting two systems so that they are not mutually coupled.

Patent GB-589146-A (GB)
Title: Manufacture of azo-dyestuffs
Filed: 1944-12-01
Abstract: Azo dyestuffs are manufactured by coupling an o-hydroxydiazo compound containing at least one sulphonic acid group with a 2-amino-6-alkoxynaphthalene free from further substituents, and, if desired, treating the product with an agent yielding metal. Suitable o-hydroxydiazo compounds are those produced by diazotizing o-aminophenolsulphonic acids which may contain further substituents, e.g. halogen atoms, alkyl or nitro groups.  Coupling may be effected in an acid, preferably a weakly acid, medium, and may be accelerated by additions of various kinds, e.g. alcohol, pyridine or sodium acetate.  For the metallization there may advantageously be used agents yielding chromium, especially compounds of tervalent chromium, the treatment with which may be conducted in an acid, neutral or alkaline medium, with or without the addition of normal salts, which may be of the kind capable of forming complexes, and of organic solvents such as alcohol or pyridine, and at atmospheric or superatmospheric pressure.  The products, especially those containing metal, may be used for dyeing or printing materials consisting of or containing animal fibres, e.g. leather, silk or wool.  Examples describe the preparation of the following dyestuffs, and their treatment with a solution of chromium formate: 5- or 6 - nitro - 2 - aminophenol - 4 - sulphonic acid, 4 - nitro - 2 - aminophenol - 6 - sulphonic acid or 2 - aminophenol - 4 : 6 - disulphonic acid --> 2 - amino - 6 - methoxynaphthalene, and 2-aminophenol-4 : 6-disulphonic acid -->2-amino-6-ethoxynaphthalene.  In a further example, wool is entered at 50 DEG  C. into a dyebath containing the chromium compound of the dyestuff 6 - nitro - 2 - aminophenol - 4 - sulphonic acid --> 2 - amino - 6 - methoxynaphthalene, sulphuric acid and sodium sulphate, which is then heated to boiling, more sulphuric acid is added, dyeing completed at the boil, and the wool rinsed and finished, yielding a yellowish-green shade.  The Specification as open to inspection under Sect. 91 comprises generally the coupling of any o-hydroxydiazo compound with any 2-aminonaphthalene capable of coupling in the 1-position and containing at least one etherified hydroxyl group (e.g. an alkoxy group in which the alkyl radical may carry solubilizing substituents), which may be in the ring not containing the amino group, advantageously in a b -position. Glycerine mono-(2-amino-6-naphthyl)-ether is specified as an additional coupling component, e.g. in example (1) above.  Reference is also made to the use of the products for colouring plastic masses and lacquers.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in automatic flow-interrupting devices
IPC: F16K31/48
Filed: 1935-08-29
Abstract: 462,032. Clockwork-actuated valves. NEWMAN, A. Aug. 29, 1935, No. 24174. Convention date, Aug. 15. [Class 135] [Also in Group XXXVII] A device for automatically interrupting the flow of gas, liquid or electricity after a predetermined interval comprises a setting pointer 2, movement of which from its zero position releases a switch lever 3 so that the latter can be moved into a locked position to open a valve in the fluid conduit or close contacts in an electric circuit, and during such movement winds up a spring 18 which gradually restores the pointer 2 to zero position, the pointer in such position releasing the lever 3 so that it returns to its initial flow-interrupting position under the action of the spring 18. The lever 3 is held in its inoperative position by the engagement of one arm 12 of a spring- controlled locking-lever 11 with a pin 14 on an extension 15 of the lever 3. When the pointer 2 is moved from its zero position against a stop 7 to setting position indicated on a dial, a pin 9 on a disc 8 fixed to the pointer moves away from an arm 10 of the lever 11 so that a controlling spring 26 causes the lever 11 to rotate and release the lever 3. The lever 3 can now be moved to flow-permitting position, shown dotted, Fig. 3, against a stop 5, and is locked by the engagement of another arm 13 on the lever 11 with a pin 16 thereon. During this movement, the lever 3 winds up the spring 18, the other end of which is attached to the pointer 2 and rotates it towards its zero position. This rotation is controlled by an escapement mechanism 21 .. 24 geared to a toothed disc 19 against which bears a spring 25 fixed to the disc 8 and forming a friction drive. When the pointer reaches zero position, the pin 9 engages the arm 10 of the locking-lever 11 so as to release the lever 3 which moves back to flow interrupting position under the action of the spring 18 and is locked in such position by the members 12, 14.

Filed: 1961-07-05
Abstract: 983,239. Switching diodes. MALLORY BATTERIES Ltd. July 5, 1961 [July 7, 1960], No. 24246/61. Drawings to Specification. Heading H1K. A diode has three successive semi-conductive zones forming an emitter junction between one outer zone and the central zone and a congruent collector junction between the central zone and the other outer zone, the width of which is not greater than the diffusion length therein of minority carriers injected from the central zone. A voltage applied across the device forward biases the emitter junction and reverse biases the collector junction forming there a potential barrier region which will extend completely across the outer (collector) zone when the applied voltage reaches a given switching level, at which point the potential across the barrier region regeneratively collapses due to a regenerative increase in the concentration of minority carriers injected into the central zone by the emitter junction. The diode, of silicon or germanium, may be formed by the grown-junction technique, by fusion processes, or by diffusion of donor (acceptor) impurities into each end of an N (P)- type wafer. Ohmic contacts are welded to each of the two outer zones. Increasing the resistivity of the collector zone will decreas the switching voltage. In the embodiment described boron is diffused for 18 hours at 1280 C. into an 18 mil. N-type silicon wafer forming two uniform P zones at the ends of the wafer, then the zone which is to be the collector zone is lapped to a thickness of 0À2 mils. and the semi-conductor body etched to remove surface impurities.
