Title: Process for the manufacture of aqueous emulsions
IPC: C09K23/00
Filed: 1934-07-02
Abstract: Oil-in-water emulsions are obtained by the use of water soluble salts of sulphuric acid esters of a normal primary alcohol having at least 8, preferably 12--18, carbon atoms as emulsifying agents, the sulphate ester salt being made in situ by dissolving the free acid of the ester in the oil phase and mixing it with an aqueous solution of a suitable base, such as oxides, hydroxides or salts with weak acids of sodium, potassium, ammonium, lithium or magnesium.  Suitable sulphuric acid esters include n-lauryl-1-sulphuric acid and the corresponding esters of myristyl, cetyl, stearyl, oleyl and ricinoleyl alcohols.  Oils which may be emulsified include medicinal paraffin oil, Neat's foot oil, olive oil, castor oil, cottonseed oil and petroleum lubricating oils.  The proportion of emulsifying agent may vary from 0,02 per cent to 10 per cent by weight of the oil, preferably between 0,05 and 2 per cent.  According to examples: (1) 30 gms. of heavy paraffin oil, 30 gms.  Neat's foot oil and 2 gms. of the sulphuric acid ester of lauryl alcohol are mixed together and mixed with a solution of 2 c.c. of 25 per cent caustic soda solution in 36 c.c. distilled water, with high speed stirring at room temperature.  The resulting emulsion has a pH value of 8 and may be used for soaking natural silk to remove serecin.  (2) 30 gms. of heavy paraffin oil and 1 gm. of the sulphuric acid ester of lauryl alcohol are mixed and added with stirring to 1 c.c. of 25 per cent caustic soda solution dissolved in 18 c.c. of distilled water.  (3) 0,5 pt. by weight of 25 per cent caustic soda solution are added to 29 pts. by weight of water, and boiled.  0,5 pt. by weight of the sulphuric acid ester of lauryl alcohol is added to 70 pts. by weight of asphalt at 120 DEG  C., and this is added to the boiling caustic soda solution.  Other known emulsifying agents may be used in addition, also known stabilizing agents or agents to inhibit oxidation of the oil may be added.  The emulsions are readily diluted with water.  Specification 358,612 is referred to.

Title: Arrangement in plants equipped with internal combustion motors, and wherein the exhaust gases from the motors are used for generating steam
IPC: F01K23/14
Filed: 1922-07-21
Abstract: 183,482. Aktiebolaget Vaporackumulator. July 22, 1921, [Convention date]. Steam regenerative accumulators.-Relates to the application of a steam storer to a stationary plant comprising internal-combustion engines, the exhaust gases from which are used to generate steam for power production or heating purposes. The steam storer, which consists of a tank of water or other liquid wherein the steam condenses, is adapted to store the available surplus steam and deliver it when required. In one arrangement, Fig. 2, the exhaust gases from the constant-load internal combustion engines A pass to boilers C and generate steam which is supplied past a valve H to a pipe system E connected to a steam-storer F and a turbine K and also, by way of a reducing-valve M, to further piping 0 connected to steam consumers P. The valve H serves to keep the pressure in the boilers C constant, the storer F storing any steam surplus and supplying any deficiency. In another arrangement, Fig. 4, the steam from the boilers U passes through a turbine R before being conducted to the storer system E, F, and the pipe system O leading to consumers with a variable steam consumption. By means of a centrifugal governor T, an increased demand for steam by the turbine can be met by admitting steam to the low-pressure stage S from the storer F.

Filed: 1927-08-04
Abstract: 294,775. British Hartford-Fairmont Syndicate, Ltd., (Hartford-Empire Co.), Aug. 4. 1927. Glass-annealing leers.- In a glass-annealing leer heated by liquid fuel, the supply of fuel to the burner is controlled by a thermostatic device tn accordance with the average temperature of a zone extending across substantially the whole width of the leer. As shown, the liquid-fuel burner 11 delivers into a nre-box 10 which communicates with flues beneath the floor 13 of the leer, the heat-responsive element 25, which controls the fuel supply, extending through these flues from one side of the leer to the other. The burner 11 is supplied with compressed air and fuel by pipes 20, 19 respectively, the latter pipe being fitted with a valve 29, Fig. 5, having a vertical spindle 33 carrying a pinion 34 which meshes with a rack 35 secured to the rod 37 of a piston 38 operating in a cylinder 43. The piston is urged in a direction tending to close the valve 29 by a spring 39 and is moved in the opposite direction by air which enters the cylinder 43, when the spring-controlled ball valve 53 - is closed, from the main 20 through pipes 45, 50. The element 25 comprises a nickel tube 24 surrounding and fixed at one end to a rod 23 of fused quartz, the tube 24 being secured at the other end to a bracket. 26 having an aperture through which passes the free end of the rod 23. This end carries a thimble 64 in contact with a spring plunger 59 which, on movement of the rod 23 due to expansion of the tube 24, moves inwardly and, by means of the adjustable member 57 carried by it, opens the valve 53 to allow air to escape from pipe 50 through pipe 56 to the atmosphere and thus the piston 38 to move in a direction partially to close the fuel valve 29. The cylinder 43 is provided with adjustable stops 40, 44 at its ends, the former being adjusted to prevent the complete closing of the valve 29. On fall of temperature within the leer, the contraction of the tube 24 produces a movement of the rod 23 to push the plunger 59 outwardly and allow the valve 53 to seat, thus causing air to enter the cylinder 43 and open the valve 29. The automatic control of the fuel supply may be thrown out of operation by closing the handoperated cock 46 in the air pipe 45, regulation of the fuel supply then being effected by the screw stop 44.

Abstract: 1,038,626. Aerials; radio navigation. STANDARD TELEPHONES & CABLES Ltd. May 24, 1963 [May 30, 1962], No. 20747/62. Headings H4A and H4D. A Doppler-effect radio beacon comprises a hollow metal circular cylinder 1 having parallel slots 2 forming a circular array of slot aerials, means to feed the slot aerials cyclically and consecutively around the circle with a wave of frequency F 1 , means to feed the aerials in a similar order with a wave of frequency F 2 , the two feeding cycles being always diametrically opposite on the circle and progressing at a constant rate G, and means to radiate a third wave of frequency F 3  equal to (F 1 +F 2 )/2 via one or more slot aerials. Aerials, Figs. 1, 2 and 3.-The waves of frequency F 3  may be generated by an energized loop aerial on the axis within cylinder 1, the waves from which will propagate out of all the slots; or from a horizontal loop outside the cylinder but on the axis thereof. The commutative feed of energy on frequency F 1  is capacitative via rotating arms 10, 11, Fig. 3, a given slot being energized by feeding to metallic portions on either side of it; a similar arrangement is provided for frequency F 2  energy. To protect the aerial system from hot gaseous jets &c. on an airport runway 3, Fig. 2, steel cylinder 1 and its feeders are installed in a well; the runway is rebuilt with asbestos 4 concreted over. An aircraft may then be guided to rest over the cylinder. Radio navigation.-The beacon provides for elevation and azimuth determination by an aircraft receiver. Frequency F 3  is made equal to (F 1  + F 2 )/2 by utilizing the sidebands of a carrier of frequency F 3  for the frequencies F 1 , F2; wave F 3  is amplitude-modulated at frequency G. At the receiver the frequency deviation d of a beat wave f=F 1  (or F 2 )-F 3  is measured by a frequency discriminator; if D is the frequency deviation in a horizontal plane, the angle of elevation of the receiver is sin<SP>-1</SP>(d/D). For evaluation of azimuth, the phase of the amplitude modulation on wave F 3  is compared with the phase of the output of the frequency discriminator.
