Title: Improvements in or relating to systems of remote indication of electrical quantities
IPC: G08C19/16
Filed: 1936-03-02
Abstract: 462,778. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. March 2, 1936, No. 6233. [Class 40 (i)] [Also in Group XL] In a signalling system in which impulses are transmitted to an indicating instrument at a rate depending on the speed of rotation of a measuring instrument, the two directions of rotation are distinguished by changes in the impulse ratio. In the system shown, a meter 2 which may rotate in either direction according as energy is being fed from a substation to bus-bars or vice versa carries two impulse discs 3, 5 giving respectively short makes with long breaks, and long makes with short breaks. The discs are associated with two optical systems 6, 8 reflecting light at a mirror 10 on to a photo-electric cell 11 and connected up according to the direction of rotation of the meter 2 by contact 14 of a phase-reversal relay 12. The impulses produced in the cell 11 are transmitted over the line 16 either directly or by means of a carrier to a valve 17 associated with two relays A, B. Relay A is quick-acting and responds to all impulses controlling through condensers 20 the amount of deflection of a central-zero indicator 18. Relay B is slow acting and responds only to the impulses with a long make-period to reverse the connections to the indicator 18. The pitch of the teeth of discs 3, 5 may be different to give an open or closed scale on one or other side of the central zero.

Roller-and-sheet recording-apparatus; integrating apparatus.-Relates to recording and integrating means forming part of a gas calorimeter of the continuous flow type in which the calorific value of a gas is obtained from the rise of temperature of a stream of water heated by the gas. Liquid-filled thermometers subjected to the temperatures of the incoming and outgoing water are respectively connected to flexiblediaphragm expansion-chambers T11, T12 also filled with liquid. The chamber T11 has a lug T23 to which is pivoted at T25 an arm T24 which is also pivotally attached to a nut T29 through which passes a screw T28 the end of which enters a recess T27 in the chamber T12. The outer end of the arm T24 has a number of holes T30 into one of which one end of an arm T31 can be inserted. The capacity of the cold thermometer-bulb is greater than that of the hot bulb in the ratio of 10 to 9 and the distance between the pivots T25, T29 is one tenth the total length of the arm so that when the thermometers are equally heated no movement of the arm T31 results; the holes T30 pivoted in any one of a number of holes in an facilitate this adjustment. The arm T31 is connected to a hinge link T34 which can be arm T38 to alter the scale of the record, a fine adjustment being afforded by a spring T37 and nut T36. The arm T38 is secured to the pen axis T35 carrying the frame I, which is provided with points entering cone-and-slot recesses Th, Ts in the pen frame T41 which carries a reservoir T42 from which ink is conducted by a fine tube T43 protruding at its outer end through the end T39 of the frame.

Filed: 1957-02-25
Abstract: A mixture containing one or more aliphatic monocarboxylic acids having at least 4 carbon atoms and one or more aliphatic dicarboxylic acids having from 4 to 22 carbon atoms is treated to effect separation of the mono- and di-carboxylic acids by introducing the mixture into an aqueous solvent consisting of a solution of a polyhydric alcohol or a mono-alkyl ether thereof in water, and contacting the resulting mixture with a straight chain hydrocarbon solvent, the mono-carboxylic acids being taken up in the hydrocarbon phase whilst the dicarboxylic acids remain in the aqueous phase. Examples of polyhydric alcohols are glycol, propylene glycol, glycerol and trimethylene glycol and suitable ethers are the mono-methyl, -ethyl, -propyl and -butyl ethers of ethylene glycol.  A suitable solvent to water ratio is from 0.25 : 1 to 10 : 1 by volume. Suitable hydrocarbon solvents are petroleum fractions having boiling points in the range of 30 DEG  to 100 DEG  C., e.g. 40 DEG  to 60 DEG C.  The starting carboxylic acid mixtures may be those obtained by disruptive oxidation of unsaturated fatty acids, e.g. those obtained by treatment of the latter with permanganate in acetone solution, or by ozonolysis, or by treatment with nitric acid, or mixtures of sodium dichromate and sulphuric acid.  Examples are given for the separation of (1) caproic acid and dodecanedioic acid, (2) and (4) pelargonic and azelaic acids, (3) butyric and adipic acids, and (5) docosanedioic and stearic acids.

Filed: 1926-03-13
Abstract: 271,589. Synthetic Ammonia & Nitrates, Ltd., Smith, P. A., and Smith, H. G. March 13, 1926. Acetic acid; alkali acetates.-Alkali acetates are obtained by reaction between methanol and an alkali formate or by the interaction of methanol, carbon monoxide, and a caustic alkali or alkali carbonate. The reaction between methanol and an alkali formate is preferably carried out by treating the molten formate with vaporized methanol at a temperature of 200-300‹ C. The formate may be the crude product obtained by the action of carbon monoxide on a caustic alkali, and its melting point may be lowered by the addition of another substance such as water, or by the use, for example, of a mixture of sodium and potassium formates. To inhibit the decomposition of the formate into oxalate, the reaction may be performed under pressure and in presence of hydrogen; gases containing hydrogen and methanol vapour, such as the gases from a methanol synthesis plant, may accordingly be used. The alkali acetate may be directly treated, by known methods, to yield acetic acid. The reaction of methanol, carbon monoxide, and caustic alkali or alkali carbonate is carried out under pressure and at such a temperature, not exceeding 240‹ C., that a liquid phase is maintained during the reaction. An example is given according to which crude methanol and a slight excess of causticsoda or soda ash are placed in an autoclave into which carbon monoxide is pumped until the pressure reaches 50 atmospheres. The temperature is then raised to 200-220‹ C. and is maintained at that point for two or three hours, whereafter the pressure is released. The crude sodium acetate may be purified or the contents of the autoclave may be treated directlv with sulphuric acid and the acetic acid distilled off. Instead of carbon monoxide, water gas or other gases containing carbon monoxide may be used. without special purification. nr the mixture of methanol. hydrogen. and carbon monoxide derived from a methanol synthesis plant may be employed
