THE NEW PATENTS LATELY ENROLLED. 
in 
MR. WILLIAM NICHOLSON’s (sSOHO- 
SQUARE,) for various Improvemenis in 
the Application of Steam to ufeful Pur- 
pofes, and in the Apparatus required to 
the jame. Granted November 22, 1806. 
NHS invention, and the manner in 
which it is to be carried into effect 
and practice, are detcribed as follows: 
Mr. Nicholion converts water into iteam 
by the application of heat in any of the 
uinal methods, and permits the faid {team 
to rufh out through one or more aper- 
tures, of fuch magnitudes refpectively as 
may be beft adapted to the feveral pur- 
poies. He then permits the current or 
currents of fieam to pais through a por- 
tion of the atinofphere, or of air com- 
maunicating with the atmofplere, or of 
iuch other gas, or elaitic fluid, or vapour, 
or imoke, as it may be defirabie thould 
come into contact with the faid fteam. 
Further,. he difpofes a tube or pipe (of a 
circular bore m preference) m fuch a 
polition, with regard to the faid current 
er currents of fieam and air, or of iteam 
and gas, eiaftic tluid, or vapour, or {moke, 
as that the iaid current or currents fhall 
pais through the faid tube or pipe,-and 
be carried to its place of dettination. 
He alfo gives unto the faid tube or pipe 
a greater diameter, or fize of perforation, 
than he allows for the firt efcape of the. 
ficam from the place where the fame was 
pr-duced; and he makes the faid tube or 
channel either cylindrical or of iuch 
other figure internally as may he beit 
fuited to produce that effeét which is 
well known to men of fcience by the 
name of the lateral action of fluids, the 
effect cf which faid lateral attion of 
fluids is particularly te be obfervyed in 
the ancient and well-known machine 
ior producing a blaft by the fall of a 
fhower of water throngh an upright pipe; 
and in this invention the lateral action 
of the-current of fteam takes place with 
regard to the furrounding air, or gas, or 
elattic fnid, or vapour, which is carried 
along with it, fo that the fleam is made 
to produce an eifect of the fame nature 
as, but more powerful and advantageous 
than, is produced by the water in the 
faid ancient machine; and Mr. N. ap- 
phes the faid curre: st of fteam and air, 
_ or of fteam and gas, elafie finid or va- 
potr, or fmoke, to fuch purpofes of ma- 
nuizéturing or philofophical chemufiry as 
may be ulcfal according to the nature of 
tie ieveral cafes refpectively, namely — 
(1)}.for agitating, or for impregnating, or 
fur driving over in diftiiauen water or 
other iiuids, or (2) for oxidating, corrod- 
ing, ruiting, or aitering the neiuie “Soc 
tate of lead or other metals, or miteshic 
ores, or mineral bodies, more cr jets 
heated or ignited by the a&ti@m Of fire sm 
tubes, or muiiles, or tefts, or pimp or 
veffels, or upon hearths srates, er other" 
wile fo placed, fituated, or expe ted, a8 
may be beft adapted ter the chianges in- 
tended to be produced in the faid metais, 
metallic ores, or mineral bodies. by 
means of the faid current herein before 
mentioned and defcribed; or (3) he 
caufes the faid current of fteam and at- ~ 
motphene air to pats through the tube or 
pipe here before defcribed, ur m jome 
cafes fimply through an aperture or hole, 
into a receptacle or ar vetlel, wherein 
the tleam 1s fubjected to condenfation, 
and from which veflel the atmofpheric 
air, thus deprived of its ffeam, 1s convey— 
ed to a furnace or any other place con- 
taming fire or burning materials, 1 in orde 
that the faid eurrent or blaft of air hall 
and may excite and increafe the firength, 
rapidity, and efiect of the combuition.

MR. WILLIAM HYDE WOLLASTON’s, (ST. , 
MALY-LE-BONE,) for an Injirument 
whereby any Perjon may draw tin Per- 
J[pettive, or may copy or reduce any 
Print or Drawing. Granted December 
4, 1806. 
This inftrument confifts principally oF 
two reflecting furfaces, fo placed with re- 
gard to each other,-as that the firft of 
the faid furfaces fhall be whelly or in 
part interpofed between the eye of the 
artiit and the paper, or other material on 
which the delimeation of any object or 
view, or the copy or reduétion of any 
tketch, print, or drawing, fhall be in- 
tended to be made; and the faid reflect- 
ing furface fhell be fo inclined toward 
the fecond refleéting farface, that objects 
re by that fecond reflection may 
lo. be again refleéted by the firtt, and 
aoe by that means be rendered vilible to 
the eye after two reflections, when the 
fight 1s direéted towards the faid paper 
or other material. And, in order that 
the faid paper cr other material may be 
feen with the fame eye, as well as the 
doubly-reflected object,the firft-mentioned 
reflector is made of fuch materials as 
fhall permit the faid paper or other ma~ 
terial to be feen through the fame; or es
