NEW INVENTIONS.

some fabric or material which will keep them in place, and to which 
buckles, tapes, or other means of fastening are applied to secure them 
to any desired part of the body. The plates, strips, or blades may 
be of any form, according to the part to which they are to be applied. 
The moisture of the body will generally suffice to excite the bandages to 
action. They may, however, be excited by vinegar, or diluted acid, more 
j or less strong. 
Fixing Artificial Teeth. — Mr. D . W . Ransom , patentee. — These 
improvements are more particularly applicable when fixing teeth in 
vulcanite or like mounted bases. Artificial teeth have before been made 
with metal pins, which have usually been bent in opposite directions, in 
order that when the base of vulcanite, or other suitably formed base, has 
been constructed and rendered hard, the teeth may be held securely to the 
base. Here the patentee forms the pins, or it may be a single pin, with a 
l screw thread or threads thereon, or with notches : if two or more pins be 
applied to a tooth they may be arranged parallel to each other ; but it is 
better that they should incline away from each other. 
Producing Gas. — Mr. TV . H . BucJcland , patentee. — In producing gas 
for illuminating and heating purposes according to this invention, air or 
gas is carburretted by causing it to pass over the surface of, or through, 
woven fabrics or fibrous or spongy substances which have the property of 
sucking up and exposing the liquid hydro-carbon in a finely divided 
state. 
Treating Steel and Iron Prepared by the Pneumatic Process. 
—Mr. J. Mushet , patentee. — The essence of this invention consists in 
thoroughly mixing, without the agency and deteriorating effects of the 
pneumatic blast, melted speigel eisen or other melted alloys — such as 
alloys of tungsten of iron, or titanium of iron — with melted steel or 
malleable iron prepared by the pneumatic process from melted pig iron or 
cast iron, which mixing the patentee effects either by the use of two or 
more pneumatic or decarbonizing vessels, each containing melted steel or 
malleable iron made by the pneumatic process, to the steel or malleable 
iron in one or both of which two vessels the melted speigel eisen or other 
melted alloy has been added, the contents of one vessel being poured into 
the other, so as to internally mix and make the whole of uniform com- 
position. 
Reproducing or Obtaining Facsimiles of the Veins, Pores, 
Knots, and Figures of Wood upon Paper and other Surfaces. 
— R. A. Brooman, patentee. — In carrying these improvements into practice 
a smooth plank or piece of wood is covered with a coating of paint, which 
is made to penetrate the pores and veins of the wood ; all the paint 
remaining upon the smooth surface of the wood is removed by a scraper, 
leaving only such of the paint as has penetrated the pores and veins. A 
very thin plate of copper, or other metal, is coal ed on both sides with a 
thin layer of wax, and this metal plate is applied upon the wood prepared 
as above described. The metal plate is pressed strongly upon the wood 
by a roller or otherwise, and the paint is thus forced from the pores or 
veins of the wood, and adheres to the wax upon the metal plate. The 
plate is then removed from the wood, and all the parts of the wax to
