Title: Process of refining glyceride oils and fats
IPC: C11B3/06
Filed: 1945-03-09
Abstract: A crude vegetable glyceride oil or fat containing as impurities free fatty acids, non-fatty colloidal matter, and colouring matter, is refined by neutralising it with dilute aqueous alcoholic caustic alkali at 60 DEG -150 DEG F. in quantity just sufficient to saponify the free fatty acids and to solvate the non-fatty impurities and a substantial part of the colouring matter but insufficient to salt out the saponified products, thereby avoiding emulsification of the neutral oil and conditioning the mixture to have liquid foots, then separating the liquid foots from the neutralised oil, and washing and drying the oil.  Preferably, after the treatment with the aqueous alcoholic caustic soda or potash, the oil is treated with a small quantity of aqueous caustic soda or potash to remove further amounts of colouring matter.  The process is particularly applicable to the refining of crude cottonseed oil.  The alcoholic caustic soda may contain 8-10 per cent. of ethyl alcohol and 2-5 per cent. of caustic soda and the amount may be such that the excess of caustic soda is equivalent to 0.2-1 per cent. of free fatty acid.  The oil may be refined in a conical bottomed kettle provided with heating coils and variable speed agitation, or in a centrifugal apparatus. The caustic soda solution may be sprayed into the oil during vigorous agitation. Mixing may be continued for 20 minutes or more after which the oil is allowed to settle and the foots liquid is drawn off.  The oil may then be treated with aqueous caustic soda solution of 12-20 DEG B<\>ae in an amount equivalent to 0.5-1 per cent. of free fatty acid. This treatment may be effected at 130 DEG -180 DEG F.  The oil may then be washed with water at 190 DEG -200 DEG F. In an example, crude cottonseed oil containing 1-2 per cent. of free fatty acid is refined by treatment with 7-10 per cent. of an alcoholic caustic soda solution containing 0.7-1.0 per cent. of alcohol and excess of caustic soda equivalent to 0.2-1 per cent. of free fatty acid.

Title: Improvements relating to phonographs for recording telephone conversations
IPC: H04M1/65
Filed: 1919-03-10
Abstract: 138,196. Ullmann, H. March 10, 1919. Telephone communications, recording.-A phonograph is arranged to record outgoing and incoming messages by operating a hand-lever which puts the recording-stylus in engagement with the record, connects the recording-coils in separate communication with the microphone and telephone circuits, and releases the phonograph motor. Fig. 3 is a side elevation of the phonograph, Fig. 4 shows a detail of the driving-mechanism, and Fig. 6 shows the electrical connexions. The record blank 16 is mounted on a mandrel shaft 14, which is driven from the motor shaft 6 by a belt 13, and is geared to the feed-screw 20, the recorder 24 being traversed thereby in the usual manner. The control lever 26, when moved to the right, lowers the recorder on to the record, and moves the switch arm 27 into engagement with the insulated halves 28<a>, 28<b> of a rod 28. The switch arm 27 has two contacts on its inner face, the upper one co-operating with the upper contact 28a to connect one of the recording-coils in series with the microphone M and battery S, the lower contacts 28<b> connecting one of the recording-coils in the line circuit 34. The circuit through the contact 28<a> includes an electro-magnet 12 which, when energized, attracts an armature 9 and releases a ratchet-wheel 8 loosely mounted on a shaft 35 of the motor. The wheel 8 has a lug 37 on one side which lies in a segmental gap 38 in a disk 36 fixed to the shaft 35, a spring 41 being interposed between the lug 37 and one side of the gap. The motor starts up when the ratchet-wheel 8 is released, and when the detent is dropped, the motor runs a short distance, compressing the spring 41 before it is arrested. The electro-magnet 12 is shunted by a condenser C or by a non-inductive resistance to afford a path for the voice currents. When the control lever 26 is in non-operative position, the circuits of the recorder coils 24 arc opened at the contacts 28a. 28b, and the microphone circuit is maintained through a contact K, The microphone circuit also includes a hookswitch G for the receiver H. The front 4 of the casing and half of the top-plate 2 are pivoted on vertical hinges to permit access to the record.

Abstract: 177,158. Sulzer FrÞres Soc. Anon., (known as Sulzer Akt.-Ges., Geb.). March 21, 1921, [Convention date]. Regulating; valve-gear.-In engines in which liquid fuel and compressed air are admitted to the combustion chamber, one or more compressed-air inlets are provided in addition to the usual compressed-air inlet valve which is operated when the fuel is injected, the additional inlets being controlled by valves arranged to come into operation only when the load exceeds a predetermined amount. Fig. 1 shows the usual inlet valve a and an additional valve h arranged to be operated respectively by valve levers e, i mounted on an oscillating shaft f and engaging shoulders g, k on the valve stems. The angle through which the shaft f is oscillated is varied by hand or governor so as to alter the arc through which the levers are moved. For light loads, the levers only move sufficiently to open the valve a, but for heavy loads, the levers swing through a greater arc, and the additional valve also is opened. The valve h may also act as a fuel valve, flooding of the valve being prevented at small loads by a second valve in the fuel-supply pipe, which allows fuel to pass to the valve h only when the latter is operative. This fuel valve may also be used to shut off the supply of fuel at all loads ii desired. The valve h may be actuated by means independent of that for the valve a. Where there are several additional valves, some may admit air only and others fuel only. The valves may be disc or slide valves, instead of needle valves as shown.
