Thomas Todd, of Swansea, South Wales, 

 orgaii-biiilder, for Ills improvement in pro- 

 ducing tone upon musical instruments of 

 various descriptions. — Nov. 22. 



Samuel IJrown, of Windmill-street, 

 Lambeth, Surrey, for his engine or instru- 

 ment for effecting a vacunm, and thus pro- 

 ments, which require a fine face, he ducing powers by which water may be

size applied warm, and suifered to cool 

 before the mould be used. The re- 

 quired works are then formed by using 

 hard and durable substances imbedded 

 in such calcareous cements as will set 

 quickly and without shrinking, and 

 will harden in a short period. For 

 ceilings and cornices and their enrich- 



mixes as quickly as possible a small 

 quantity of plaster of Paris with water 

 to a creamy consistence, and instantly 

 applies a thin coat with a soft brush to 

 the face of the mould, fixed and pre- 

 pared for use as aforesaid ; and in the 

 mean time another small quantity of 

 plaster or other cement having been 

 quickly tempered with water to the 

 consistence of mortar, he applies it 

 with a trowel as a thicker coat at the 

 back of that first applied with a brush, 

 and then instantly fills up the body of 



raised and machinery put in motion. — 

 Dec. 4. 



Archibald Buchaoan, of Catrine cotton- 

 works, for a certain improvement in ma- 

 chinery heretofore employed in spinning- 

 mills in the carding of cotton and other 

 wool, whereby the top cards are regularly 

 stripped and kept clean by the operation 

 of the machinery without the agency of 

 hard labour. — Dec. 4, 



Josiah Parkes, of Manchester, Lan- 

 cashire, for a certain method of manufac- 

 turing salt. — Dec. 4. 



George Minshaw Glascott, of Great 



the workwith cement, in which bricks, Garden-slreet,Wliitechapel, brass-founder 

 tiles, or squared stones, are intro; and Tobias^Michell, ot Upper Thamcs- 



duced in regular courses; or in which * " " 



bricks, tiles, stones, cleau-worked 

 gravel, ballast, or shingle, or other 

 hard and durable substances, are in- 

 troduced, and heterogeneously incor- 

 porated ; but in such manner that the 

 cement may be in sufficient quantity to 

 retain the distinguishing properties 

 before enumerated. 



For walls, columns, pilasters, and 

 other enrichments to buildings, the 

 cement is to be tempered with water 

 to the consistency of thin mortar, and 

 applied and supported with a trowel 

 to the prepared face of the mould, and 

 the body of the work instantly formed 

 as before described ; and after the 

 moulds are removed, and the cement 

 has acquired firmness without being 

 too hard, he removes any little ine- 

 quality of surface, and, smoothing the 

 same witli a trowel or handfloat, uses 

 water and a little tempered cement 

 when necessary, in the manner plas- 

 tered surfaces of walls are usually 

 finished.
