Title: Process for the preparation of synergistic antifoam compositions
Inventor: ARONADE KENNETH
IPC: B01D19/04
Filed: 1953-10-13
Abstract: Synergistic antifoam compositions useful in the textile, cosmetic, petroleum, paint, paper, food, laundering industries and for emulsion polymerization are obtained by the combination of a trialkyl phosphate, or mixture of a tri-alkyl phosphate and an alcohol containing at least 30 per cent by volume of trialkyl phosphate, with an emulsion containing at least 1 per cent by weight of methyl- or hydroxymethyl-polysiloxane.  Improved results are obtained when the trialkyl phosphates are added to the known DC Antifoam A emulsions after these have been re-emulsified with additional wetting agents, e.g. polyoxyethylene sorbitan laurates, oleates and stearates.  This re-emulsification permits separation of the most finely dispersed portion of the commercial antifoam emulsion from the heavier greasy portion by filtration, the filtrate being again separated, e.g. by use of a Laval milk separator, into a watery layer, which is rejected, and an oily layer which is mixed with the trialkylphosphate.  Compositions specified comprise (1) 700 ml. tributyl phosphate, 50 ml. "Tween (Registered Trade Mark) 80", 20-50 ml. DC Antifoam A emulsion fractionated as set forth above; (2) 300 ml. tributyl or triethyl phosphate, 300 ml. isopropyl alcohol, 20-60 ml. DC Antifoam A emulsion fractionated or not.  Specifications 631,049 and 689,306, [Group III], are referred to.ALSO:Synergistic antifoam compositions useful in the textile, cosmetic, petroleum paint, paper food, laundering industries are obtained by the combination of a trialkyl phosphate, or mixture of a tri-alkyl phosphate and an alcohol containing at least 30 per cent by volume of trialkyl phosphate, with an emulsion containing at least 1 per cent by weight of methyl- or hydroxymethyl-polysiloxane.

Upon operation of release member 7, a control slider 1 moves under action of a spring 6 until a lug 21 thereon engages a lug 20 of a retaining lever 17. At the same time a changeover switch 40, 41 is actuated to commence the delay action timing, and to energize the electromagnet. When the electromagnet is de-energized armature lever 12 pivots under the action of spring 15 to move lug 20 out of the path of lug 21 and slider 1 continues its movement in direction B, during which an extension 53 thereon operates change-over switch 48, 53, which energizes the electromagnet again and a control extension 10 thereon engages armature extension 14 to return the armature into engagement with the electromagnet. The closing blade 23, held in its initial position by a pin 24 on opening blade 25 is thus held during shutter opening by a pin 22 thereon by retaining lever 17. At the end of its movement, slider 1 engages a pin 30 on an opening lever 28 which is pivoted clockwise to free pin 27 on opening blade 25 and allow opening blade to uncover aperture 26. Exposure timing then continues until the electromagnet is de-energized to release pin 22 and allow the closing blade to cover aperture 26. The mechanism is reset by movement of slider 1 to its initial position.

The buoy a of rubber or other flexible material is housed in a cylinder b in the torpedo. A valve tube c on the buoy is pushed into an inflating tube d which is mounted on a piston e in the cylinder b. A non-return valve f in the tube d is connected by a cord g to the bottom of the cylinder. Air-tight connection between the tubes c, d is made by two or more levers i<1>, i<2>, the upper ends of which are connected by toggle links to a cord k passed round the buoy. The levers are arranged to press together flanges on the tubes c, d, packing being interposed. A tube m<1> is connected to the compressed air reservoir of the torpedo and a valve n is opened by a system of springs and levers o, p, q after a plug r of soluble material has been dissolved by the sea water. This valve permits air to pass through a pipe m<2> into a cylinder s<1> and operate a piston s<2> connected to the sliding cover t of the cylinder b. At the end of its travel the piston s<2> opens a port u through which air passes by way of a pipe m<3> to the cylinder b, driving the piston e upward and expelling the buoy. The cord g, when tightened, opens the valve f, and the buoy is inflated. The cord k is tightened by the inflation of the buoy and opens the lovers i<1>, i<2>, releasing the buoy as shown in Fig. 2. A non-return valve v prevents escape of air from the buoy. The compressed air then escapes through the tube d and forms a channel through any mud or ooze. A relief valve z is provided on the buoy, which is moored by a rope wound on a reel mounted on the piston e.
