polarity, for effecting a preliminary separation of the material
into layers, and a separator magnet or magnets having pole-
pieces provided with correspondingly arranged bars for re-
moving the upper magnetic layer from the material, and
having a belt travelling over its face to carry the magnetic

substantially as described. (4.) The arrangement for sup-
porting the magnetic plane, the tray, and the feed-hopper on

which the tray can be inclined at different angles without
disturbing the relative arrangement of the parts. (5.) A
magnetic separator constructed and operating substantially
as described with reference to the drawings.

heated to between above 212° Fahr. and its boiling-point.
(2.) Generating steam by bringing water (preferably in a
heated condition) in direct contact within a closed vessel or
the initial cylinder of an engine with an animal or vegetable
oil or fat (preferably olive or cotton-seed oil) heated to be-
tween above 212° Fahr. and its boiling-point, substantially as
described. (3.) Generating steam by bringing water, prefer-
ably in a heated condition, into contact, within a closed
vessel, with a series of coils or pipes through which is circu-
lating an animal or vegetable oil or fat, preferably olive or
cotton-seed oil, heated to between above 212° Fahr. and its
boiling-point, substantially as described. (4.) In a steam-
generator, an oil-heater such as 1 having a series of enclosed
troughs such as 4 subjected to heat from oil or other
burners, the oil-outlet having suitable connection with a
generator such as 15 having shallow trays such as 18, and
having provision for the injection of water and outlet of the
steam, substantially as described and explained, and as illus-
trated. (5.) In a steam-generator, an oil-heater such as 1
having a series of enclosed trays such as 4 subjected to heat
from oil or other burners, the oil-outlet being in suitable
connection with the initial cylinder such as 25 of a series,
into which cylinder the heated oil is drawn or forced, and
pump such as 59 with suitable valves for injecting water
into the cylinder, substantially as described and explained,
and as illustrated. (6.) In a series of single-acting expan-
sion-cylinders for utilising high-pressure steam, a valve-
spindle such as 44 having recesses such as 45 within a
loose sleeve such as 46 and fixed sleeve such as 47, the
said spindle being actuated from the main shaft to open and

close the ports of the cylinders in rotation to permit of the
expansion of the steam therethrough, and the said loose
sleeve being provided with a hand-lever to reverse the admis-
sion and emission of steam in the cylinders, substantially as
described and explained, and as illustrated. (7.) The im-
provements in generating steam consisting of the combina-
tion and arrangement of parts substantially as described and
explained, and as illustrated in Figs. 1, 2, 3, and 4, and 18.
(8.) In the utilisation of high steam-pressures in a series of
single-acting expansion-engines, the employment of an
arrangement of valves such as that described, and as illus-
trated in Figs. 5 and 6 and 8 to 18 of the drawings.
