the other constructions of lace machinery, we doubt whether the mode of working set out in the specification, will be found sufficient for the purpose of producing the described articles.-[Inrolled in the Inrolment Office, October, 1835.]

TO HENRY WILLIAM NUNN, of Newport, in the Isle of Wight, lace-manufacturer, for his invention of certain improvements in manufacturing or producing certain kinds of embroidered lace, parts of which improvements are applicable to other purposes.-[Sealed 21st April, 1836.]

THE subjects of this patent are described as improvements on the foregoing, and consist of the following particulars: First, producing, by bobbin-net machinery, the ornamental edges in imitation of the purled head or edge of Valenciennes lace, which is effected by retarding the delivery of the ornamenting thread at intervals, and thereby constructing the heads or edges; also producing spots or ornaments on the body of the groundwork, in imitation of Valenciennes lace, by means of one guide and one spotting bar in place of two, as employed under the previous patent.

Second, in producing the blond edging uncombined with lace net, having two or more purls, connected together by means of plain threads, thereby forming a fabric of blond lace of any width constructed of purl alone, connected by threads.

Third, in producing" Neige" with escollops, and also lace net, having escolloped edges, in bobbin-net machines.

Examples of the several kinds of lace proposed to be made as the subjects of this patent, are appended to the specification, but of which no very intelligible description can be given beyond that which is stated above.

As regards the machinery exhibited, it is merely some detached portions of a traverse warp machine; and the principal feature of peculiarity seems to be a contrivance for contracting, in certain places, the sides of the strips of work called tapeing, or of the loops of the purledged escollops, for the purpose of producing particular patterns, called Valenciennes. The ornamenting thread is furnished from a bobbin above, the rotation of which is occasionally retarded by a weighted cord, thereby preventing the delivery of the thread, and consequently, contracting the extent to which the thread shall be carried, either for producing the variable breadths of the tapeing stripe, the shapes of the spots to be worked upon the net, or for the lengths of the loops of the escolloped purl edges.

As these productions are intended to imitate Valenciennes lace, it is proposed that they should be made of brown cotton, and only half bleached when dressed.[Inrolled in the Inrolment Office, October, 1836.]

To STEPHEN HAWKINS, of Milton House, near Portsmouth, in the county of Hants, gentleman, for his invention of certain improvements in warming-pans or apparatus for warming beds and other purposes.-[Sealed 24th May, 1834.]

THIS invention applies to a particular description of warming pan, to be heated by means of hot water, the

proposed object being a more safe and convenient mode of using and filling the pans with hot water.

The Patentee divides his invention into two parts, viz. an improved construction of warming-pan, and improvements in the manner of filling the same.

The first part of the invention will be better understood by reference to Plate IX., fig. 8, which represents the construction of warming-pan described by the Patentee: a, is the pan, made of copper or any other suitable metal; b, the handle, of wood, screwed into a stem at the back part of the pan, or affixed to it in any other convenient manner. An opening is made in the back of the pan, for the purpose of admitting the hot water, which is to be closed by a screw c, when the pan has been filled.

The Patentee observes that warming-pans are sometimes filled by pouring water down the handle, or by removing the handle; but this constitutes no part of his invention, the handle in this pan always being fixed and retained in its proper place.

The second part of the invention, viz. the manner of filling the pan, is shown at fig. 9, which represents an improved funnel: d, is the pipe of the funnel, which must be inserted in the opening above mentioned; e, is a plug, or rather a float, suspended by a rod f. When the water is poured through the funnel into the pan, as it rises the float will be raised also, and close the end of the pipe d, and thereby prevent overflow.

The Patentee says, in conclusion, " Having now described my invention, and in what manner the same is to be performed, I claim, in the first place, the adaptation of an opening distinct from the handle, by which the pan may be filled; and, in the second place, I claim the improved funnel, with float, for the purpose of filling

the same, which latter improvement may be applied to other useful purposes.-[Inrolled in the Inrolment Office, November, 1834.]

TO JEAN BAPTISTE MOLLERAT, of Leicester-square, in the county of Middlesex, manufacturing chemist, for his invention of an improvement or improvements in the manufacture of gas for illumination.-[Sealed 2d May, 1837.]

THE Patentee states that hydrogen gas and the oxide of carbon, not possessing in themselves sufficient luminous properties, it has been the practice, or at least it has been suggested to pass them over the surface of distilled oil of coal, tar, and other such matters containing bituminous or carbonaceous substances, or to pass them through peculiarly-formed burners in connexion with coal tar, for the purpose of causing them to take up or absorb carbon; but upon the gas cooling, it has been found that a partial separation of the gases have taken place in the gasometer, when obtained by the first process; and that, in the second case, a constant and careful attention to the operation was necessary, in order to keep the chemical matters properly combined.

The present improvement is designed to produce the combination of the hydrogen with the carbon, in such a way, as shall cause them to remain permanently held together in the gaseous form, and capable of being employed for the purposes of illumination.

The hydrogen gas may be obtained from the decomposition of water in any of the known ways, or by any other process, which is not claimed as new. This gas, at a very high temperature, is to be brought in contact

with the volatile products of oil, whether obtained from animal, vegetable, or mineral, and when this contact takes place, an immediate absorption or blending of the gases will result, and their union become permanent.

The Patentee considers that various forms and constructions of apparatus might be employed to effect this object, none of which, however, he claims, but confines his invention to the permanent combination of the above chemical matter, in the way described, for the purpose of producing gas for illumination.

A second feature of invention, is the use of a very cheap and common mineral or earthy matter called bituminous schistus (slate), which is to be subjected to the process of distillation, for the purpose of evaporating an oil which it contains. This oily vapour may be employed for combining with the hydrogen obtained from water, in the way first described, for the production of illuminating gas at a very cheap cost.-[Inrolled in the Inrolment Office, November, 1837.]

To THOMAS ALCOCK, of the parish of Claines, in the county of Worcester, lace-manufacturer, for his invention of certain improvements in machinery already in use for the manufacture of bobbin-net lace.-[Sealed 15th December, 1831.]

THIS invention applies to that particular class of machinery for making lace in which the bobbin carriages slide to and fro through the machine, between the warp threads, upon circular combs; and are actuated by the reciprocating rotary motions of fluted rollers working into teeth or indentations at the under parts of the carriage.
