Title: Improvements in or relating to butter and butter process
IPC: A23C15/06
Filed: 1947-08-06
Abstract: 671,656. Butter and milk fat concentrate. CHERRY - BURRELL CORPORATION, and SUGAR CREEK CREAMERY CO. Aug. 6, 1947 [Dec. 6, 1940], No. 21374/47. Class 84 Milk fat concentrate which may be converted into butter, is obtained by subjecting cream containing milk fat in the dispersed phase to reduced pressure, subjecting the cream while at the reduced pressure to the direct action of steam, concentrating the milk fat by subjecting the treated cream while at a temperature above the melting point of said fat to a centrifuging action, and separating the concentrated fat in the continuous phase from the other constituents. In a preferred method, cream having a milk fat concentration of 30-40 per cent is warmed in vat 1 to a temperature of 90-110‹F. The cream passes to filter 4, through which it passes at about 135‹F. having been heated by steam through pipe 5<SP>1</SP>. The filtered cream is further heated to about 150-160‹F. and after passing flash pasteurizer 7 in which it reaches a temperature of 190-194‹F. it enters supply tank 10 and is then fed to vacuum steam pasteurizer 12 which may be of the type described in U.S.A. Specification 2,022,420. Water vapour and other volatiles leave by passage 14. The treated cream is then separated in centrifuge 17, and a product consisting of at least 80 per cent with fat passes into vat 20 and is subsequently mixed with salt, starters and flavours from vat 25. The mixture is cooled in vessel 29 and is tempered in unit 31 and the resultant butter is then packaged.

Abstract: 1,139,526. Jointing by rolling; making composite sheets. OLIN MATHIESON CHEMICAL CORP. 16 May, 1966, No. 21571/66. Headings B3A and B3M. A process for making plate-like composite article having a core of an iron base alloy, and a cladding of a dissimilar metal, includes rolling together the core, after heating it to between 300‹ and 1350‹ F., and the unheated cladding at a speed of at least 100 feet/min. and at a reduction of 35-75%, the core and cladding contacting each other between the bite of the rolls with an included angle of from 5-22 degrees. The cladding, which may be applied to one or both sides of the core, can be of a dissimilar iron base alloy, or an alloy of Cu, Pb, Ag, Ni, Zu, Sn, Cr, Co, Ti or Al. Before bonding, the core and cladding may be cleaned and mechanically roughened. In an example, a core of 0À10% C iron alloy in a strip of 0À040 inch gauge was clad with a Cu base alloy containing 89% Cu, 0À04% Pb, balance Zu with a gauge of 0À010 inch. After cleaning the metals in alkaline solution and abrading their surfaces with a wire brush, the core was heated to 800‹ F. and the two metals rolled at 150 feet/min. with 65% reduction. The included angle of the core and cladding was 18 degrees at the roll bite, the cladding contacting one of the rolls before the core. The resultant composite had a gauge of 0À018 inch with the bonding area at the metal interface being at least 25% greater than the planar surface area of the composite.

Abstract: 631,991. Phase difference and power factor measurements. EVERETT, EDGCUMBE, & CO., Ltd., and GRUCHY, J. N. DE. Aug. 7, 1947, No. 21671. [Class 37] To measure phase difference, e.g. power factor, on a permanent magnet moving coil, the current in a load Z is applied over transformer CT to a network of resistances R1, R2, rectifiers X1, X2, resistances R3, R4, and condensers C1, C2, and the voltage is applied across R5 over a network of resistances R6, R7, R8 and non-linear resistances R9, R10, so that the voltage across R5 is independent of variations of the voltage applied to the load-circuit Z. To make the circuit additionally independent of current variation, the output winding of the transformer CT may be connected to R1, R2 over a series resistance and a shunt non-linear resistance, (Figure accompanyirig Complete Specification, not shown).

Abstract: 837,883. Cooling cement clinker &c. ZEMENTAULAGENBAU DESSAU VEB. [formerly MASCHINENFABRIK POLYSIUS]. July 16, 1956, No. 21995/56. Class 51 (2). Apparatus for cooling cement clinker discharged from a pulverulent fuel-fired rotary kiln 1 comprises a shoot 4 formed with air nozzles 5 leading to a spiral wall 10 formed with air nozzles 11 and disposed above a basketshaped rotary grate opening into a cylindrical shoot 12. Cooled clinker from the latter falls on to a rotary plate 13 having an adjustable plough 15 guiding it into a hopper 16 from which it falls on to an endless conveyer 17. The rotary grate comprises separate rings 7, 8 and 9 in which or between which air slots are formed and the said rings may be rotated independently of one another in direction or speed. Cooling air is supplied through the nozzles 5 and 11 through the grate and through ports 14 in the shoot 12. A cylindrical baffle 28 extends downwardly in the cooling chamber to touch the clinker or the grate and radial partitions extending outwardly of its wall divides the cooling chamber into sections 18 and 19, the former supplying heated combustion air to the kiln. Passages controlled by valves 30 allow air to pass from the cylindrical baffle 28 to the sections 18 and 19. In a modification, Fig. 5 (not shown), the plate 13 is replaced by a rotary frusto-conical grate built up of separate rings. A further modification, Fig. VI, has a single rotary ring 7 disposed above a hopper 32 leading to the central shoot 12 having a concentric inner shoot defining an air space 34.

Title: Process of dewaxing oils
IPC: C10G73/06
Filed: 1937-08-10
Abstract: In the separation of wax from oils by chilling with a liquefied normally gaseous hydrocarbon, the solution of wax-containing oil is the liquefied hydrocarbon is suddenly chilled by injecting a stream of chilled liquefied hydrocarbon, and the mixture is forced in a stream through an elongated passage way to provide a gradual decrease in pressure on the stream and gradual evaporation of the solvent.  A wax-containing oil is fed from a tank 1 through a heater 3 to a mixer 6, to which liquefied propane is admitted from a tank 7.  The resulting solution at about 60 DEG  F. or higher is mixed with a further amount of cold liquid propane admitted at a line 57, to provide a sudden chilling <PICT:0488063/III/1> to below 60 DEG  F., whereby high melting waxes are precipitated, and the mixture passes to a reservoir 12 at about 10 DEG  F.  The mixture then passes from the tank 12 under pressure of about 80 lb. controlled by a valve 591, through one or more chilling coils 14 in which propane is gradually evaporated, lowering the temperature and precipitating the wax, until the pressure at the exit is about atmospheric.  The mixture of oil, propane and wax at about -40 DEG  F. passes to a tank 29 where vaporized propane passes to a compressor 21 and tank 7.  The mixture passes from the tank 29 to one of the filters 34.  The filtrate passes to a recovery apparatus 39 from which propane returns to the tank 7 and wax-free oil passes to a tank 43.  The wax cake is washed with cold propane from a tank 50, supplied from a tank 7 and cooling coils 44.  The washings pass to a tank 56 and are used in the first sudden chilling stage.  The wax is removed from the filter and is freed from propane in a recovery apparatus 62 from which melted wax passes to a receiver 64, and propane returns to the tank 7. Liquefied propane, ethane, propylene, isobutane or mixtures thereof may be used.  The chilling coil 14 may consist of a long pipe of uniform bore, but preferably consists a series of pipes of increasing bore connected in series.  A series of seven connected pipes from 1/8 to 5/8 " bore is specified.  At intervals in the pipe valved vapour chambers are provided from which propane vapour is withdrawn as a further control upon the evaporation and temperature gradient. Specification 411,866 is referred to.
