Title: Improvements in dyes and coloured products
IPC: C08L1/08
Filed: 1946-01-25
Abstract: Fibres, foils, films and like extruded products of fibre-forming materials soluble in organic solvents, especially cellulose esters or ethers, are coloured, e.g. in any of the ways described in Specification 551,435, with monoazo dyes obtained by coupling a diazotized aminobenzene with a coupling component, at least one of the components containing an oleoylamino radical and both components being free from carboxylic and sulphonic groups (see Group IV (c)). Thus, filaments spun from a cellulose acetate spinning solution coloured with 4-nitro-21-oleoylamino-41-diethylaminoazobenzene are of a cherry red shade, whilst wine shades are obtained with 2 : 6-dichloro-4-nitro-21-oleoylamino-41-diethyl-amino - and dimethylamino-azobenzene and brownish red shades with 4-nitro-21-oleoylamino - 41 - (N - morpholino) - azobenzene or its 2 : 6-dichloro derivative.ALSO:3-Oleoylamino-1-diethylaminobenzene is obtainable by treating m-aminodiethylaniline with a solution of oleoyl-chloride in benzene, prepared by refluxing oleic acid with a slight excess of thionyl chloride in benzene.ALSO:Monoazo dyes are manufactured by coupling a diazotized aminobenzene with a coupling component, at least one of the components containing an oleoylamino radical and both components being free from carboxylic and sulphonic groups.  Particularly suitable coupling components are 3-oleoylamino-1-dialkylaminobenzenes (e.g. 3-oleoylamino-1-diethyl-, dimethyl- and di - (b  - hydroxyethyl) - amino - benzene and 3 - oleoylamino - 6 - methoxy - 1 - diethyl- and -dimethyl-aminobenzene) and 3-oleoylamino-1-N-morpholino- and -piperidinobenzenes, which may be coupled with the diazo compounds of aniline or its nuclear substitution products in which the substituents may be alkyl, halogen, alkoxy, acidylamino or especially nitro (preferably in p-position to the amino-group), e.g. o-, m- or p-nitraniline or 2-chloro- or 2 : 6-dichloro-4-nitraniline.  Alternatively, the oleoylamino group may be present in the diazo component, as in the dyestuffs obtained by coupling diazotized aminobenzenes containing an oleoylamino group as a substituent (e.g. in the p-position) with p-coupling N-dialkylamino benzenes (e.g. diethylaniline, m-acetylaminodiethylaniline, diethyl - m - toluidine or N-di-(b -hydroxyethyl)-m-toluidine) or with other coupling components such as phenols (e.g. phenol itself, cresols, such as p-cresol, or hydroxydiphenyls, such as p-hydroxydiphenyl).

Title: Improvements in or relating to the distillation of alcoholic musts
IPC: B01D3/00
Filed: 1951-02-01
Abstract: <PICT:0718899/III/1> The process for distilling alcoholic musts according to Specification 626,658, is modified by using the bottoms from the distillation at atmospheric pressure as the source of steam for the vacuum distillation, and by inserting an additional distillation stage in order to remove volatile contaminants from the phlegms obtained from the vacuum distillation before those phlegms are introduced into the concentration stage.  The vacuum column is made larger than in the apparatus described in the earlier Specification; or two vacuum columns identical with that used in the parent Specification, are provided.  The strength of the final product is raised to 96-97 DEG G.L.  The apparatus shown comprises two vacuum columns A and A1, an atmospheric column B, a concentrating column UC, and a column, V, for the additional stage.  The must is divided into three parts, which are fed to columns A, A1 and B.  The vapours obtained at the head of column B are passed through pipes 4 and 59 into the base of column UC.  The phlegms leaving the heads of columns A and A1 are condensed; and the condensates are collected in tank P.  The bulked condensate is reheated in heat-exchanger G by the bottoms withdrawn from columns A and A1, and is then pumped through pipes 14 and 54 into column V.  The purified phlegms withdrawn from the base of column V are introduced into the base of column UC. Vinasse withdrawn at 103 DEG C. from the base of column B, is passed through pipe 20 into the left hand compartment of separator J1, where a vacuum corresponding to a boiling point of 70 DEG C. is maintained. Part of the vinasse evaporates in separator J1, and the steam produced is supplied through pipe 21 to heat vacuum columns A and A1. The liquid from the left hand compartment of separator J1 is introduced through pipe 63 into the tubes of tubular heat exchanger J; while the alcoholic vapours from the head of column UC are led to the shell surrounding the tubes.  The emulsion of liquid and vapour, formed inside the tubes of heat exchanger J, is introduced through pipe 64 into the right hand compartment of separator J1.  The steam passes off to columns A and A1 through pipe 21; and the residual liquid is withdrawn from the separator through barometric pipe 65. Rectified alcohol of 96 DEG -97 DEG G.L. is withdrawn from the upper section of column UC, condensed in condenser O, and withdrawn from the system through tube 17.  Fusel oils are withdrawn from the base of column UC by known means.  In a modification, heat exchanger J is heated by the vapours passing from the head of column B.

Title: Speed control for power system
IPC: H02P9/04
Filed: 1973-01-18
Abstract: 1423772 Automatic control of speed ABEX  CORP 18 Jan 1973 2742/73 Heading G3R [Also in Division H3] A speed control arrangement includes a generator providing a prime signal whose frequency represents the speed of a shaft which signal is used to gate a detector on and off for alternate halfcycles and also supplies a phase shifting circuit which provides a quadrature output signal, as input to the detector, whose phase shift from 90 degrees varies monotonically with variations in frequency of the prime signal from a predetermined value and where the output of the detector passes to a filter which produces a D.C. control signal whose amplitude varies as a function of the prime signal frequency and is used in a speed controller for keeping the speed of a motor constant. The phase shifting circuit, detector and filter are combined in electronic controller 14 which consists of a phase shifting network 25 including an operational amplifier having a bridged-T notch filter 27 in the feedback path to set desired operating frequency. A synchronous detector 34 comprises a transistor switch 35 which is switched on in  alternate half-cycles of the prime Signal by the squarewave output from generator 38. Thus a waveform 47 is obtained from the input signal 45 and the average value of the waveform will alter with changes in prime signal frequency. The output from detector 34 passes through filter amplifier 41 to produce a D.C. signal which can be used in a dual coil valve controlling a hydraulic motor forming the drive 11.  The controlled speed can be altered by using variable resistors and capacitors in the notch filter. The connections of transistors and other circuit components forming the electronic controller 14 and speed control device 15 are described in conjunction with Fig. 3 (not shown).

Filed: 1957-01-25
Abstract: 880,405. Fluid-actuated valves. TECALEMIT Ltd. Jan. 10, 1958 [Jan. 25, 1957], No. 2809/57. Class 135. A fluid control valve assembly 1, Fig. 1, for controlling the flow of variable-pressure fluid so that it will be in a desired relationship to a selected pressure drop across a manually-adjustable throttle valve 10, comprises vertical and horizontal pressure chambers 4, 16 divided respectively by a diaphragm 5 or equivalent into upper and lower compartments 6, 7 and by a diaphragm 22 or equivalent into left-hand and right-hand compartments 23, 24. The diaphragm 22 is subjected to the variable-pressure (P 1 ) upstream of the throttle valve 10 transmitted through a conduit 9, the compartment 6 and a passage 17 against the action of a spring 25 to position a cam member 18 co-operable with a piston 20 to adjust the loading of a spring 21 acting on the diaphragm 5. The diaphragm 5 besides being loaded by the spring 21 is also urged downwardly by the pressure P 1  against the loading of a spring 15 and pressure (P 2 ) downstream of throttle 10 to position a valve member 12 controlling an outlet 14 from the assembly. The shape of the cam member 18 will determine the relationship between the value of the pressure P 1  and the pressure drop across the throttle valve 10. Since flow through the valve 10 is proportional to the square root of the pressure drop across it, by suitably selecting the dimensions of the components and the shape of the cam any desired relationship between the pressure P 1  and flow through the valve 12 may be obtained. In a modification, an impeller 45, Fig. 2, is fitted between the inlet 41 to the assembly and the upstream side of a manually adjustable throttle valve 49. The diaphragm 36 in the horizontal pressure chamber in this case is subjected on one side to impeller outlet pressure and on its other side to impeller inlet pressure (inlet pressure) and the loading of a spring 40 to position a cam member 39 adjusting the loading of a spring 33 acting on the diaphragm 27 in the vertical pressure chamber. The pressure drop across the throttle valve 49 and therefore the flow through the valve 30 controlling the outlet 31 is determined in a desired relationship to the pressure difference generated by the impeller 45 and therefore to the speed of the impeller.

Filed: 1939-01-28
Abstract: 524,367. Embroidery. STEVENS, A. H. (Bohleber & Ledbetter). Jan. 28, 1939, No. 3018. Drawings to Specification. [Class 112] [Also in Groups VIII, IV and IX] A destructible fabric for backing embroidery is treated, or the yarns composing it are treated with a compound containing one or more diazotizable amino groups. A fabric so treated is not readily inflammable, can be stored without deterioration, contrasts in colour with usual embroidery threads and can be diazotized away when no longer required. The completed embroidery with backing is placed in a cold diazotizing bath of any soluble nitrite with, preferably, sulphuric or hydrochloric acid. It is then rinsed, dried and sufficiently heated when a substance is liberated which disintegrates the backing. Pattern effects may be produced similarly by treating some of the yarns, or parts of the yarns, of which the fabric is composed, with a diazotizible amino group compound and then disintegrating the treated portions. Such yarns may be woven into fabric with other yarns which have not been treated. A partially destructible fabric having more intricate pattern effects may be produced by applying to a fabric treated as above described a reducing or oxidising compound or chemical such as sodium hydrosulphite, stannous chloride, titanous chloride or sodium chlorate. A paste of the compound is applied in a desired pattern to the places of the fabric where the treated yarns are to be retained. The fabric after drying, steaming and washing to remove the paste can be placed in a diazotizing bath to remove parts of the treated yarn which have not come under the influence of the reducing or oxidizing chemical. The sodium salts of the following acids are suitable for diazotizing in carrying the invention into effect, viz:-(1) 4-amino-benzeneazo-p-cresol-methyl ether-azo 7 amino-1 napthol- 3 sulphonic acid (2) diphenyl disazo-3 sulpho-7 amino-1 naphthol-3 : 6 disulphonic acid, (3) p-aminobenzene-azo-a naphthalene-azo 7 amino- 1 naphthol-3 sulphonic acid and (4) m-aminobenzoyl-6 amino-3 sulpho-1 naphthol-2 azobenzene.
