PATENTS FOR MECHANICAL AND CHEMICAL 
INVENTIONS. 
To Louis Lamzent—Rue de la Goiit, and 
Cannon-street, London—for his Invention 
of certain Improvementsin the Material and 
Manufacture of Paper.—23da Noy. 1824. 
VRNHE principle of the improvement here 
proposed consists in reducing straw 
into pulp suitable for making paper, and 
in extracting the colouring or other matter 
therefrom. Todo this, all the knots must 
be cut out of the straw, which must 
then be boiled with quick-lime and water, 
which will extract the colouring and sepa- 
rate the fibres. Caustic, potash, soda, or 
ammonia may be employed for this purpose 
instead of lime: it must afterwards be 
washed in clear water. The fibrous sub- 
stance is then submitted to the action of 
hydro-sulphuret, in order to get rid of the 
mucilaginous and silicious matters. After 
this, the fibrous material must be washed 
in successive water, until all the alkaline 
matters are removed, and there is no smell 
of the sulphur left. It is then pressed—to 
extract the waters from the fibres, and 
bleached in the ordinary way. The bleach- 
ing process being completed, the material 
Js again washed until all chemical matters 
-are entirely removed ; when it is fit to be 
-Introduced into the ordinary rag-engine 
employed for making paper. 
To CuarLtes RANDoM Baron Dr BEREN- 
_ “GER, of Target Cottage, Kentish Town, 
Sor his Discovery of certain Improve- 
ments, as to a New Method of applying 
~ Percussion to the Purpose of igniting 
Charges in Fire-arms generally, and in a 
peculiar Manner, whereby a Reduction of 
the Priming is also effectually protected 
against the Influence of Rain or other 
Moisture. 
The object of the patentee is to dispense 
with the greater part of the mechanism of 
‘an ordinary gun-lock, and to employ a 
main-spring only; which, with the assist- 
ance of a lever, will be as completely effica- 
cious in the discharge of percussion guns, 
_as the more complicated locks at present 
in use, and by no means so expensive. 
The principle of the invention consists in 
making the main-sprihg give the blow, 
_ which produces the percussion without the 
_employment of minor parts, as in the locks 
of ordinary construction. 
To Evwarp Cartwricut, Brewer-street, 
Golden-square, for his Invention of, Im- 
provements on, or Additions to Roller 
Printing Presses. —27th July 1824. 
These improvements apply to those kind 
of roller presses employed for copper-plate 
printing. 4 
The first object of the patentee being, 
to obtain a reciprocating action of the press- 
ing rollers, from arotatory motion, commu- 
nicated by the power of steam, water, or 
any other first mover; the second is a com- 
bination of several presses, with conical 
rollers, having an annular table travelling 
round, and passing between the several 
pairs: of rollers; there are several varia- 
tions of this invention. The last proposi- 
tion is the combination of several printing 
presses, set round in a circle, to be ac- 
tuated by one large rotatory wheel in their 
centre, and having an annular or ring- 
formed table travelling round, between the 
several pairs of rollers, upon which : the 
copper-plates and papers are to be laid, 
passing through the press as the table pro- 
ceeds. The rollers of these~presses must 
necessarily be frustums of cones, the apexes 
of which would meet in the centre of the 
annular table; the rollers are, therefore, so 
mounted in frames, upon their axles, that 
each pair respectively shall meet in a hori- 
zontal line; and the upper rollers, having 
toothed wheels upon their axles, taking into 
the large central wheel, which is actuated 
by steam, or some other power, the whole 
of the printing presses are put in motion, 
and continue driving the annular table 
round, upon which the workmen place the 
plates and the paper. 
To Jamus Viney, of Shanklin, Isle of 
Wight, for his Invention of certain Imn- 
provements and Additions to Water- 
Closets. —6th May 1824. 
The object of these improvements is to 
discharge the soil, &c. from the basin of a 
water-closet, more effectually than has yet 
been effected. For this purpose, the patentee 
proposes a new mode of placing the basin 
and its pipes. The improvement is effected 
by the discharge-pipe having a glass open- 
ing outwards into a pipe, placed perpen- 
dicularly on the outside of the house: this 
pipe is open to the air above, but leads 
down to the sewer below. Another pipe, 
leading from a reservoir of water, placed 
above the water-closet, is, at its lower end, 
divided into two branches. A valve is 
placed in the pipe, to regulate the dis- 
charge of water; and when the valve is 
opened, the’ water flows through the branch- 
pipes into a tube, which extends round the 
upper edge of the basin. This tube has 
either a long slit, or a number of perfora- 
tions on its under side, through which the 
water flows, and cleanses the side of the 
basin: when the closet is not in use, there 
is a shutter which is to be lowered so as 
to close the mouth of the discharge-pipe, 
and then the water is allowed to stand a
