NEW INVENTIONS
DAGUERREOTYPE CAMERA.- M. Masrtiner has stated to the French
Academy of Science, that he has discovered the means of carrying on the Daguerreotype
process on a gigantic scale, as compared with what is now done. He can, he says,
Daguerreotype an entire panorama, embracing 150 degrees. His process consists in
curving the metallic plate, and causing the lens which reflects the landscape to turn by
clock-work. The lens, in turning, passes over on one side the whole space to be
Daguerreotype, and on the other side moves the refracted luminous cone to the plate, to
which the objects are successively conveyed.
Mr Joseph Hurd, of Shoreham, Vt. has secured Letters Patent, of an apparatus for
separating or clarifying liquids by application of centrifugal force. It is a well-known fact
that mucilage or sugar, as well as mineral and saline substances, have a greater specific
gravity than water, though the particles thereof, will not readily separate from water by
mere force of gravity; but when a mixed fluid, or turbid water is put into a violent rotary
motion, in a cask or cylinder, the centrifugal force will drive the heavier particles to the
sides of the vessel, while the clear water remains in the centre.
A NEW INVENTION FOR CLEANING COTTON, completed by Mr.
Philip Ault, of Natches is composed of wire cylinder within a box, in which revolves a
shaft with arms capped with rails; from the rail spikes or pins project, which separate the
locks containing the seeds from each other, knock out the trash and dust, and pass the
cleaned cotton over the cylinder down into the gin stand. The shaft is driven by the same
power that drives the gin requiring but little force. It is a valuable assistant to the
Planter.
INDIA RUBBER.-There is no end to the many valuable objects to which India
Rubber may be applied. A new one has been discovered, and that is the inner sheathing of
ships, where sheathing paper is now used in small sheets and where this new rubber can be
applied in wide strips extending the entire length of the vessel. The rubber being
indestructible and impervious to water, renders it an additional means of preventing leaks,
while sand spread over it puts an end to all ravages of insects that infest salt water.
AN IMPROVED COTTON-GIN.-A. M. Groat is about introducing a Gin for
long staple Sea Island cotton. It is expected to clean at least, 100 pounds per day, whereas
the gins now in use will clean only about 25 pounds. The seed is separated without
breaking.
A new machine for breaking stone, has been lately constructed at Brooklyn. Its
construction is on the principle of a large hammer or beater, operated by a movable-steam
engine. It is intended for the West Indies, to be used in McAdamizing roads.
We would invite our readers to look at the advertisement headed "Rare Project." There is real benevolence to men, in the plan proposed. As success must attend some of the inventions, and much gain may follow at little risk, it commends itself to all who desire human improvement. We gladly commend, not only the project, but also the company, as worthy the confidence of the public.
