An aerosol composition comprises, in addition to a liquid propellant, a caustic alkali, a polyhydric alcohol having a boiling point of at least 185 C., and a nitrogen containing anionic surfactant. Suitable specified propellants are dichlorodifluoromethane, dichlorotetrafluoroethane, or a mixture of these, the propellants being insoluble in the aqueous concentrate, but forming an emulsion which when discharged from a pressurized container forms a stabilized foam. Examples of suitable nitrogen containing anionic surfactants are given, and ethylene glycol, propylene glycol, and dipropylene glycol are specified as suitable polyhydric alcohols. The caustic alkali may be sodium or potassium hydroxide. A cleansing composition comprises an aqueous solution of a caustic alkali, a polyhydric alcohol having a boiling point of at least 185 C. and a nitrogen containing anionic surfactant. Caustic alkalis specified are sodium and potassium hydroxide or mixtures thereof. High boiling polyhydric alcohols specified are ethylene glycol, dipropyleneglycol, and propylene glycol. Anionic surfactants may be selected from compounds having the formulµ: wherein in the first formula above n is an integer averaging 4, R represents the various hydrocarbon groups found in natural amino acids, R 1 COOH represents coconut fatty acids and M represents sodium, potassium, ammonium triethanolamine or other organic amines, in the second formula n is an integer averaging 20, R is as defined above and M is as hereinbefore defined, in the third formula R 2  represents the fatty substituent from lauric acid containing from 10-14 carbon atoms and M is as defined above. The composition may also contain water soluble thickeners such as sodium carboxymethyl cellulose or amylopectin, a foam stabilizer such as the triethanolamine salt of oleic acid.

Title: Improvements in or relating to a process of recovering products from fermentation residues
IPC: C12F3/00
Filed: 1943-11-24
Abstract: <PICT:0585807/III/1> In a process for the spray drying of fermentation residues in inert gas at 900 DEG F. or above, e.g., as described in Specification 559,742, spontaneous combustion of the separated solids when discharged into the atmosphere is prevented by discharging them first into a stream of cool inert gas from which they are then separated and discharged from the drying system.  After the solids have been separated from the hot inert gas, the latter is cooled to remove condensible components; part of the resulting cool inert gas may then be used to cool the solids before the latter are discharged into the atmosphere.  The fermentation residue is fed through pipe 5 and preheater 7 to tank 11 from which it flows by gravity, to the rotating atomizing disc 14 of spray dryer 12 into which hot combustion gases are introduced through conduits 16 and 17. The gases and suspended matter, withdrawn through conduit 20, enter heat-insulated separator 22 having a receptacle 23 for collection of separated solids.  The gases pass on through conduit 24 and up tower 25 through which an aqueous solution, containing glycerine and other condensible components separated from the hot gases, circulates.  The washed gases are then freed from entrained liquid in vessel 33 and a portion thereof is blown through pipes 40 and 42 to tower 44 in which it is cooled by a water spray.  The cool inert gases then enter pipe 48 which is connected by pipe 49 to valve 50 through which the hot solids are withdrawn from receptacle 23.  The solids are carried along to separator 53 wherein they collect in receptacle 54 from which they are withdrawn through valve 55.  The gases pass on through pipe 56 and are recirculated to cooler 44.  To avoid leakage of gas containing condensible constituents from receptacle 23, a pipe 57 controlled by valve 58 delivers cool inert gas from pipe 48 to the receptacle.

Abstract: 683,498. Machines for making concrete blocks. CAWOOD WHARTON & CO., Ltd. Aug. 3, 1951 [Aug. 8, 1950], No. 19707/50. Class 87 (ii). A pallet clip or holding means, for incorporation in a block moulding machine in which the mould is turned over and inverted after filling, comprises a horizontal plunger or plungers spring-urged to engage the pallet and means to retract the plunger or plungers and release the pallet on inversion of the mould, the release being effected by a moving part on the machine. A bracket comprising two plates 7, 8 held by studs 9 and spaced by ferrules 10, 11 is welded to the mould 1, and two plungers 5 pass through holes in the brackets and are connected by a bridge 13. Springs 14 between the plate 7 and the bridge 13 urge the plungers towards the mould. To place the pallet 4 on the mould the plungers 5 are held retracted by the engagement in reverse 24 therein of pegs 18 on a bridge 19 which is urged in the required direction (upwards in Fig. 1) by a spring 23 surrounding a plunger 20. When the plungers 5 are released, by the depression of the plunger 20, an inclined strip 6 at their ends presses on the corner of the pallet 4 and keeps it in place. Retraction of the plungers S is effected after inversion of the mould by cam action of a suitable projection from the moulding machine on an inclined surface 15 cut in the bridge 13.

Filed: 1920-07-08
Abstract: 147,727. Montupet et Cie. June 12, 1914, [Convention date]. Casting-machines; metalpouring.-Metal is introduced into a mould a by withdrawing the air therefrom, but is restrained until the evacuation is complete either by a valve a<1>, Fig. 4, or by evacuating the crucible o with the mould, and then admitting air or a neutral gas, such as nitrogen, at atmospheric or a greater pressure to the crucible. The mould is covered by a bell f, resting on packing e, which is evacuted through a valve v, Fig. 4, the valves a<1> and y being closed. The crucible is then raised till the pipe c', heated by a coil e', dips in the metal. The valve a<1> is then opened to fill the mould and tl:en turned as shown in Fig. 4 to discharge the metal in the pipe c<1> by admitting air through a passage d'. Air is then admitted to the bell by the valve y, the casting is removed from the mould and the valve plug a<1> is removed and cleared. In the modification shown in Fig. 1 the bell f and crucible o are evacuated through pipes r, t, then air or other gas is admitted to the crucible through a pipe s to force the metal up the pipe n, heated by flue gases, into the mould a, which is then moved to the right on rails l by a screw h to sever the runner, to admit air through a passage i thus allowing removal of the bell and then to admit air through a passage g<1> into the pipe n and allow the metal therein to flow back to the crucible. In another modification the screw h may be attached to a block having distributing passages to a number of moulds.
