hour the so-digested berries in about twice their original weight of water, separating the berries from the resultant liquid, and heating and concentrating by evaporation the liquid; and then mixing the liquid so produced with the liquid obtained from the berries by the first digesting process, substantially as described. (3.) The production of extract of coffee by digesting green or roasted, or partially roasted, coffee-berries with water at a high temperature in a closed vessel, cooling the digested mass in a closed vessel, and removing the resultant liquid from the berries as by pressure and filtration, substantially as described. (4.) In apparatus for carrying out the process specified in the preceding claims, a digesting-chamber, the inlet to which is controlled by a rotary plug, formed with pockets adapted to receive berries and to deliver them to the digesting-chamber, means for admitting a certain quantity of hot water under pressure into the digesting-chamber and heating the contents of the digesting-chamber to a high temperature, say, about 370° Fahr., a cooling-chamber, a second rotary plug controlling communication between the outlet of the digesting-chamber and the inlet of the cooling-chamber, and means for causing berries delivered to the digesting-chamber to pass through and into and through the cooling-chamber, substantially as described. (5.) Apparatus according to the preceding claim wherein the cooling-chamber is provided with a water-jacket that is kept cool by a cold-water coil passing through it, substantially as described. (6.) Apparatus suitable for the production of an extract of coffee, comprising in combination berry digesting and cooling apparatus according to claim 4, a mill or mills into which the contents of the cooling-chamber are discharged and which is adapted to crush the berries and express the liquid therefrom, and a filter or filters into which the liquid is discharged from said mill or mills, substantially as described. (7.) Apparatus of the kind specified in the preceding claim, wherein the mill comprises a roller rotating eccentrically within a casing and adapted to crush the digested berries between it and the casing so as to express the liquid therefrom, a scraper being arranged between the top of said roller and its casing so as to remove the dried refuse from the berries, substantially as described. (8.) In apparatus for use in the production of extract of coffee, digesting and cooling devices constructed, arranged, and operating substantially as described with reference to and shown in the drawings. (9.) Apparatus for use in the production of extract of coffee, constructed, arranged, and operating substantially as described with reference to and shown in the drawings.

No. 17132.—22nd October, 1903.—NIELS BENDIXEN, of 23, Kronprinsensvej, Frederiksberg, Denmark, Chemist. Improvements in and relating to the sterilisation of milk.

Claims.—(1.) Method of sterilising milk, characterized by the fact that the preparatory heating with the contingent introductory proceedings, the sterilising proper (viz., the raising of the temperature from 50° C. to 128° C.), and the cooling, with contingent complementary treatment, take place each in its own part of the sterilising apparatus, and that the sterilising-vessel is emptied by the pressure of two or three atmospheres in the sterilising-vessel, and that this pressure is reduced by the cooling arrangement, after which reduction of the pressure the sterilising-vessel is filled with hot milk from the first heater, in which it is preparatorily treated, substantially as described. (2.) In the method claimed in claim 1, the arrangement that the sterilising-vessel is only partly emptied, in order to avoid scorching, substantially as described. (3.) In the method claimed in claim 1, the arrangement that the sterilising-vessel is not shut until the temperature is raised to 100° C., substantially as described. (4.) In apparatus for carrying out the method claimed in claim 1, a steriliser characterized by the fact that the first heater, the sterilising-vessel, and the cooling arrangement constitute independent parts of the whole apparatus and are connected with each other in order to obtain a continual working, substantially as described. (5.) In apparatus of the kind claimed in claim 4, the arrangement that the mouth of the outlet-pipe is arranged at the level to which the stirring movement brings the surface of the quantity of milk necessary to cover the heating-walls in order to avoid a complete emptying of the sterilising-vessel, substantially as described. (6.) In apparatus of the kind claimed in claim 5, an outlet-pipe characterized by the fact that such outlet-pipe is curved, and may be adjusted by turning in such manner that its mouth is brought farther from or nearer to the turning-axis of the milk, substantially as described. (7.) Apparatus for the sterilisation of milk, constructed, combined, and arranged, and having its parts adapted to operate, substantially as described with reference to the drawings and for the purposes specified.
