No. 15750.—11th December, 1902.—AUGUSTE GAULIN, of 170, Michel Bizot Street, Paris, France, Constructor. System for intimately mixing milk.

Claims.—(1.) An apparatus combined with a process for mixing liquids of heterogeneous composition, such as milk and the like, characterized by the passage of the liquid under strong pressure between surfaces pressed elastically one against the other and adjusting themselves exactly together, so as to secure the disintegration of the smallest particles of the liquid, substantially as set forth. (2.) The mechanical process for mixing liquids of heterogeneous composition which consists in causing the liquid to pass under heavy pressure, firstly through capillary orifices of invariable diameter, then between the terminal surface of the capillary apparatus and the surface of a valve of agate or other hard material pressed strongly by means of a spring against the said capillary apparatus, and adjusted in such a manner as to apply itself exactly thereto, substantially as set forth, in combination with the apparatus specified. (3.) The improved mechanical process for mixing milk and the like as set forth, which consists in exposing the milk under heavy pressure as set forth to a temperature of about 85° C. between surfaces pressed elastically one against the other and capable of adjusting themselves exactly together, substantially as set forth, in combination with the apparatus specified. (4.) An apparatus for the carrying-out of the process set forth, comprising pumps actuated alternately, and a capillary apparatus through which the liquid is forced by the said pumps, in combination with a valve of hard material pressed by an adjustable spring against the outer face of the capillary apparatuses, the contact faces of the valve and the apparatus respectively being exactly adjusted one to the other. (5.) In the improved apparatus combined with the process set forth, the actuation of the pumps, and of the eccentric shaft which operates them, in combination with a motor shaft having a fly-wheel and gearing connecting the said motor shaft to the said eccentric shaft, transmitting to this latter rotary motion at a reduced speed, substantially as and for the purpose set forth. (6.) In an improved apparatus combined with the process as set forth, the use of a filter in the aspiration-tube of the pumps, substantially as described. (7.) In an improved apparatus combined with the process as set forth, the filter with hermetic closure constructed and operating substantially as described with reference to the drawings. (8.) In an improved apparatus combined with the process substantially as above set forth, the arrangement of an air-escape valve at the upper part of the pressure-tube for the liquid, for the purpose of assisting the operation of the pumps, substantially as set forth.

No. 15751.—9th December, 1902.—GEORGE JOHN HOSKINS, of Wattle Street, Ultimo, Sydney, New South Wales, Engineer. Apparatus for regulating the intermittent squeeze and intermittent feed in machines for closing the locking-bar joints of wrought-iron pipes.

Claims.—(1.) In machines for closing the locking-bar joints of wrought-iron pipes, a main shaft on which is keyed a cam, the cam surface of which is divided into approximately two semicircumferential concentric segmental surfaces of different radii and connected by drops, in combination with appliances for alternately, intermittently, and successively operating (a) the hydraulic gear for squeezing the locking-bar joint, and (b) the gear for feeding the pipe forward in order to bring the locking-bar joint intermittently under the operation of the squeezing-ram as specified. (2.) In machines for closing the locking-bar joints of wrought-iron pipes, a cam such as that referred to in claim 1, in combination with a pendant rod adapted to rise and fall synchronously with the rotation of the cam, such rod carrying at its lower end, and acting as fulcrum to, a swivelling-arm adapted to engage with a slot in the spindle of the hydraulic valve gear for working the ram, as and for the purposes specified. (3.) In machines for closing the locking-bar joints of wrought-iron pipes, a cam such as that referred to in claim 1, in combination with a crank-pin from which depends a rod the lower end of which is connected to a bell-crank lever adapted to operate suitable appliances for feeding forward the carriage upon which is placed the pipe, the locking-bar joints of which have to be closed, as specified. (4.) In machines for closing the locking-bar joints of wrought-iron pipes, the cam D, pendant rod J, swivelling-arm m, slotted valve spindle O, and hand-lever N connected to one end of the swivelling-arm m, and adapted to throw the same in and out of engagement with the valve-spindle, as and for the purposes set forth. (5.) In machines for closing the locking-bar joints of wrought-iron pipes, in combination, the cam D, pendant rod J, swivelling-arm m, hand-lever N, bell-crank arms p, p', bent lever q, link r for the purpose of releasing the hauling-gear of the feed, as specified. (6.) In machines for closing the locking-bar joints of wrought-iron pipes, the actuating and releasing-gear referred to in claim 4, in combination with hand appliances for applying additional hydraulic pressure to the locking-bar joint, as and for the purposes set forth. (7.)

No. 15753.—10th December, 1902.—JOHN JOSEPH HILL, of Denver, Arrapahoe, Colorado, United States of America, Mining Engineer. Amalgamating-apparatus.

Claims.—(1.) An amalgamating-apparatus of the class having an inclined series of ribbed quicksilver-coated copper cylinders, journalled to be rotated by the power of the pulp-flow in basins containing quicksilver, and forming intercommunicating pulp-passages between the cylinders and the bodies of quicksilver in the basins, characterized by having the passage under each cylinder constricted towards its overflow end. (2.) An amalgamating-apparatus according to claim 1 characterized by having each of the series of cylinders eccentrically journalled with relation to the longitudinal centre of its supporting basin to produce the pulp-passage under it of gradually tapering form from its inlet to its overflow side. (3.) An amalgamating-apparatus according to claim 1 characterized by having the journals of the cylinders retained by removable plates bearing on the basin-ends and carrying between opposite plates removable amalgamating-curtains. (4.) An amalgamating-apparatus characterized by having at its tailings-discharging end an inclined stationary copper plate coated on its upper side with quicksilver, and a similar plate coated on its under side with quicksilver and hinged to bear at its lower end yieldingly against the surface of the stationary plate and form thereby with a gold-intercepting tailings-passage. (5.) The amalgamating-apparatus shown and described.
