Patent GB-189825362-A (GB)
Title: Improvements in Pianofortes.
Inventor: MUNT WILLIAM GEORGE
Filed: 1898-12-01
Granted: 1899-10-07
Abstract: 25,362. Munt, W. G., and Munt, E. Dec. 1. Pianofortes.-Relates to " diapason " pianofortes wherein the hammer is made to strike strings of different pitches, reference being made to Specifications No. 4068, A.D. 1816, and No. 134, A.D. 1864. In the case illustrated, each note has the usual set of strings and one other pitched an octave below the former ones, and the main object of the present invention is to avoid the necessity for notching or otherwise mutilating the bridge for the shorter strings so as to prevent the longer ones from touching it. In Fig. 2, f is the soundboard, having bridges band c, the latter for the ordinary strings e and the former for the longer or " dia- "pason" string d. The bridge b has pins b<1> with holes or notches to receive the string, which exerts an upward pull on the soundboard. The hitch pins for the two sets of strings are at different levels. The arrangement may be modified so as to cause the diapason strings to press on the soundboard. It will thus appear that the diapason strings pass clear of the bridge c, but both sets are brought to the same level at an appropriate point so as to enable the hammer to strike them. The pins b<1> may be replaced by a continuous rail secured to the bridge by pairs of screws. Each string passes between the members of a pair, and is bent by them. Fig. 13 shows an arrangement for the strings at the wrest-plank end which enables the bridges i, j to be cast in one with the framing. The ordinary strings e rest on the bridge i, and pass through notches in the bridge j, being held down by one edge of the rail g. The diapason strings in like manner pass through notches in the bridge i and rest on the bridge j. They are held down by the opposite edge g' of the rail g. The bridges i and j of course need not be made in one with the framing. A number of modifications of the arrangement at the tuning-pin end are shown, Fig. 26 being an example. A fixed rail g presses on the ordinary strings, while a rail g<3> has screws g<2> bearing on the diapason strings. Fig. 24 shows a hitch pin plate, in which the pins can be placed either at a' for downward pressure on the soundboard, or at a<2> for upward pull. In some cases, separate soundboards are provided for the two sets of strings, the soundboard for the diapason strings lying behind the other through which the pins b<1> pass. The soundboard may also be made without bars. The dampers have projecting edges so as to reach the diapason strings, which are at a different level from the others at the points where they are damped.

Title: Improvements relating to Igniting Media or Pills for Automatic Gas Lighters.
Inventor: KILLING CARL
Filed: 1899-11-03
Granted: 1899-12-30
Abstract: 22,027. Killing, C. Nov. 3. Lighting gas.-Porous catalytic igniters are prepared by impregnating meerschaum or similar material with a solution of the salt of a rare earth, and then drying and calcining to cause the deposition of the oxide of the rare earth in the pores of the meerschaum prior to its treatment with a solution of platinum chloride. In an alternative process, the igniters are treated with a solution containing salts of both platinum and a rare earth, the igniters prepared by either process being finally dried and reduced. Platinum wires, which may be coated with rare. earths, are then attached. These igniters, when used with incandescent burners, do not cause that reduction, in the illuminating power of the mantle, by the deposition thereon of fine platinum dust, which occurs in the case of igniters consisting of combustible woven fabrics saturated with a solution of a salt of a rare earth and of platinum.

Title: Improvements in the Process of Electrolytically Preparing Metals or Alloys for Lithographic Purposes
Inventor: STRECKER OTTO CARL
Filed: 1900-04-10
Granted: 1901-04-10
Abstract: 6701. Strecker, O. C. April 10. Lithographic and like printing.-Plates of metals or alloys, such as of aluminium, zinc, nickel, copper, or alloys thereof, for use in lithographic printing, are provided by electrolysis with a waterretaining layer, either before or after the application of the drawing. When it is required to clean the plate again, the layer is removed by electrolysis. To form the layer, the plate is arranged as an anode, if a continuous current be used, the electrolyte employed being dilute aqueous salt solution whose anion forms with the metal of the plate the required insoluble or nearly insoluble layer, or forms a layer which may be subsequently converted into the required layer by chemical treatment, such as by the use of a dilute acid. A neutralizing-agent having weak acid qualities may be added to the electrolyte. To remove the layer, the plate is used as a cathode. When an alternating current is employed, the plate is alternately anode and cathode. Or a self-excited current may be used, in which case the plate is either anode or cathode according to the material chosen. The plate may be immersed in the liquid, and subjected to a continuous current of between 0À05-0À1 ampere per square decimetre of the cathode surface for from two to five minutes. By another method, the plate may be arranged horizontally. It is then covered with the electrolyte, and slowly and softly rubbed with a wiper impregnated with the electrolyte, and formed of a flat metal disc of about one square decimetre surface, covered with moleskin, fustian cloth, or the like, and provided with an insulated handle. The disc is connected up to the source of the current so as to form the anode. When it is required to clean a used plate by this process, the printing-ink is first removed, and the plate afterwards joined up as a cathode, using a continuous current. The electrolyte employed to form the layer is preferably a combination of an alkali and phosphorous, phosphoric or fluoric acid, such as ammonium bi-phosphate. When complex salts are used, an oxidizing - agent, such as ammonium nitrate, an organic acid such as tartaric acid, or a neutralizing-agent, such as gum arabic is employed.
