Patent GB-190003039-A (GB)
Title: An Improved System of Musical Notation and Keyboard for use in Conjunction therewith.
Inventor: BACON JAMES
Filed: 1900-02-15
Granted: 1900-08-04
Abstract: 3039. Bacon, J. Feb. 15. Keyboards for musical instruments; music notation.-The keys corresponding to notes of different names are differently coloured, and all those of the same name are coloured alike, thus, all the C's are coloured blue, the D's green, the E's white, and so on. The shorter keys are parti-coloured, and bear the colours of the natural keys between which they lie. In the notation for use with this keyboard, the ordinary staff lines are done away with, the only lines used being for the top and bottom lines of an octave which correspond preferably to the C's. Instead of the ordinary clef signatures the letters R and L are used corresponding to the right and left hands, and the time is indicated by a single numeral which shows the number of beats in a bar. Fig. 4 shows the concluding bars of "God Save the "Queen" in the ordinary and new notation. The notes are represented by dots coloured like the keys to which they correspond. A new signification is given to the tails of the notes. Thus, a horizontal stroke on an upwardly-directed tail, as in the first chord of the Figure, means that the duration of the note or chord is a whole beat ; two strokes as in the last chord, indicates two beats, and so on. Each horizontal stroke on a downwardly-directed tail, on the other hand, indicates a quarter beat. The upper line of the L clef and the lower line of the R clef both indicate the same note, middle C preferably. The various lines may be given ornamental designs and formed into a pattern.

Abstract: 23,803. Jasset, J. E., and Cinqualbre, A. E. Dec. 29. Nickel &c., depositing ; self-exciting processes.- To deposit nickel upon another metal, a solution is prepared consisting of 1000 parts of hydrochloric acid, 60 parts of nickel, 30 parts of tin, 10 parts of iron, and 30 parts of sulphuric acid. There is also prepared a solution consisting of 200 parts of copper sulphate, 50 parts of sulphuric acid, and 1000 parts of water. The surface to be coated, for example one of iron, is first thoroughly cleaned, and then coated with copper by applying the latter solution, by means of a rag or otherwise. The copper surface thus prepared, or, if a copper article is to be coated, the article itself, is then nickelplated by rubbing it with a rag dipped in succesion into the first solution, and then into tinely-powdered zinc. This process is repeated at least twice. The copper surface forms the cathode upon which the nickel is deposited, the zinc forms the anode, and the nickel solution the electrolyte. By the rubbing, the surface is also polished. Other metals, besides nickel, may be similarly deposited.

Title: Improvements in Mechanism for Grinding Flats in Carding Engines.
Inventor: FOSSEL JOSEPH
Filed: 1902-07-01
Granted: 1902-10-23
Abstract: 14,706. Fossel, J. July 1. Carding - engines.- During the operation of grinding the flats, the latter are passed between the guides 5, 11, and their working faces are pressed upwards by weighted levers 17 against the prepared under surfaces of the guides 11. The grinding-roller 8 is adjustably mounted on levers 20, the free ends of which rest on the ends of levers 30 on the shaft 31, the position of the levers 30 being.governed by an arm 33 projecting from the shaft 31 and resting against a stud 34 on a weighted lever 36, 37. The upper end of the arm 37 carries a spring bolt 42, having a head, part of which is bevelled. The end of the bolt engages between adjacent flats during the grinding operation, as shown in Fig. 3, and the gradual turning of the lever 36, 37 allows the arm 33 to turn and the grinding-roller to descend as the flat moves beneath it. The flat is thereby ground to the desired " heel " or bevel. When the grinding of a flat is completed, a bevelled surface 47 on the frame disengages the bevelled spring bolt 42, and the lever 36, 37 turns until the bolt engages between the next pair of flats, and so on. When it is not desired to use the grinding-mechanism, the mainspring 45 of the bolt 42 is disengaged, and the bolt is held in the withdrawn position by a weaker spring 49.
