Title: Improvements in Type-writing Machines.
Inventor: WHYTE JOHN GARRIOCH
Filed: 1903-10-01
Granted: 1904-09-15
Abstract: 21,058. Whyte, J. G. Oct. 1. Type-writers.-The sheet of paper to be written upon is fixed round a cylinder or platen, and the writing is effected in a continuous spiral line, so that when the sheet is removed the lines written thereon are all parallel to the upper and lower edges of the sheet. The cylinder may be vertical, horizontal, or inclined. Fig. 2 shows a vertical section of a machine having a vertical papercarrying cylinder A mounted to slide, and rotate, upon a fixed shaft D all or part of which is formed with a screw thread. A ratchet-wheel U rotates on the shaft D, and the cylinder is caused to rotate with the wheel B, by rods T fixed to the wheel and on which the cylinder can slide longitudinally. The wheel B is rotated for letter spacing by a pawl on an arm operated from a universal bar S under the key levers N. A tooth or catch R on the cylinder A engages in the screw on the shaft D, so that as the cylinder revolves it is also gradually raised. The catch R is movable and may be disengaged, when desired, for moving the cylinder to any position. A ribbon passes over the printing point, and is carried by spools and a guide on a frame H moved vertically at each depression of a key so as to lift the ribbon over the printing point as the type strikes. The frame H is lifted by a rod H<2> connected to a lever H<3> operated by the bar S. On the frame H is also a guide H<1> by which the type-bars M are engaged and centered as they strike. A casing E partly surrounds the cylinder A, and the upper end of the shaft D is carried by a removable part of this casing. The sheet of paper is wound round, and attached to, the cylinder with its edges at an angle, a flap or guide and fixing-bar being provided for attaching the paper. The edge of the flap and the fixing-bar are at the required inclination, and the edges of the paper sheet may be placed under the flap to form margins at both edges of the sheet. An alarm bell may be sounded as the adjoining edges of the sheet are nearly reached, to enable the operator to avoid typing on such edges.

Abstract: 24,936. Imray, O., [Soc. of Chemical Industry in Basle]. Nov. 16. Dyeing.-Relates to dyeing with dye-stuffs similar to those described in Specification No. 13,778, A.D. 1902. m-Amidobenzoylamidonaphtholdisulphonic acid is acted on by diazobenzene, the mixture is heated, and the dye-stuff precipitated by common salt. It dyes cotton without a mordant clear orange-red tints, which become darker and more fast to washing by diazotization on the fibre and development with #-naphthol. Instead of diazobenzene, diazoxylene may be used, producing a dye-stuff of reddish - scarlet tint. The diazo derivative of any amine of the benzene or naphthalene series, or a substitution product of a like amine, may be used, while another amidoalphylacidyl derivative of 2 :5 1 : 7 -amidonaphtholdisulphonic acid may also be used. Again, m-acetamidobenzoyl-2 : 6-amidonaphthol-1 7-disulphonic acid is acted on by #-diazonaphthalene, the mixture heated, caustic soda added, and the acetyl group driven off by heat. The dye-stuff is, after neutralization, precipitated by salt, and dyes without a mordant clear bluish-red tints. By diazotization on the fibre and development with #-naphthol, brilliant scarlet tints are obtained. Other diazocompounds, or other acetylamido - alphylacidyl derivatives of 2:5 :1 7-amidonaphtholdisulphonic acid may be used.

Granted: 1905-10-26
Abstract: 28,149. Newton, H. E., [Furbenfabriken vorm. F. Bayer & Co.]. Dec. 22. Dialkylbarbituric acids; 2-cyanimino-4:6-diimino- 5-dialkylpyrimidines.-Dialkylbarbituric acids of the general formula (R denoting alkyl radicles) are obtained by saponifying the 2-cyanimino-4 : 6-dioxy-5-dialkylpyrimidines, the 2-cyanimino-4-imino-6-oxy-5- dialkylpyrimidines, or the 2cyanimino-4:6- diimino-5-dialkylpyrimidines of the general formula (R denoting alkyl radicles, X oxygen or imino groups). The 2 - cyanimino - 4 : 6 - diimino - 5 - dialkylpyrimidines are prepared by condensing dialkyl derivatives of malonitril with dicyandiamide in presence of alkaline condensing-agents such as alkaline alcoholates, sodium or potassium, or sodium or potassium amides. In an example, dicyandiamide and diethylmalonitril are added to an alcoholic solution of potassium, and the mixture is heated in an autoclave for some hours ; the alcohol is then distilled off, the residue is dissolved in water, and the 2 - cyanimino-4 : 6-diimino-5-diethylpyrimidine is precipitated by dilute hydrochloric acid and is recrystallized from hot water. The above compound heated with a sulphuric acid solution gives diethylbarbituric acid, which crystallizes out on cooling and is recrystallized from water. Other acids such as hydrochloric, hydrobromic, or oxalic acids may be used in the saponification.

Title: Improvements in Valves for Hydraulic Presses.
Inventor: FRENCH ALFRED WILLARD
Filed: 1905-01-10
Granted: 1905-08-10
Abstract: 507. French, A. W. Jan 10. Actuating valves; cleaning valves ; lift plug or sliding valves; piston valves ; pressure - regulating valves. -- Automatic "choker" or throttle valves for use with presses are made with small notches, which allow only a small quantity of water to pass when they are kept on their seats by increased water pressure ; otherwise, the notches may be in the seats. Means are provided for opening the valves a large amount to allow a large body of liquid to pass, in order to flush the valves should they become clogged with dirt. Fig. 1 shows a sectional elevation of a valve-mechanism, and Fig. 3 shows a sectional elevation on the line 3-3, Fig 1. A hand-actuated valve b<1> and a check valve f control the passage of low-pressure water to the press, and an automatic spring-loaded change cock g controls the flow of high-pressure water, so that when the pressure in the press exceeds a certain predetermined amount the valve g is opened by the pressure of liquid on its face g<3>, assisted by the pressure of the high-pressure liquid on its lower end, and the valve f is seated by the high-pressure liquid admitted. The automatic "choker" valve I, sliding in the passage h, has an enlarged head, on which is formed a face i provided with grooves i<1> to afford a passage for the liquid when the valve is seated. The valve is normally kept off its seat by a weighted lever L, so that the liquid can flow rapidly to the press, and it is seated by the pressure acting on its enlarged upper face so that the liquid can then only flow through the small notches i<1>. The passage of liquid to the valve chamber is controlled by the usual screw-down valve K. Fig. 4 shows a modified form of choker valve, in which the seat is omitted, and the upper portion of the valve, which is of the same size as the part below the contracted parts, formed to allow the passage of liquid, extends into a chamber m, which acts as a dash-pot to prevent sudden vibrations due to the pulsations of the pump. The downward motion of the valve is limited by the shoulder m<1> Fig. 5 shows a form of choker valve, in which the weighted lever is not necessary. In this form, the valve chamber communicates at its opposite ends with the inlet and outlet passages of the casing by ports n, n<1>, and intermediate of its ends by ports n<2>, n<3>. The valve has enlarged cylindrical portions o, o'. The upper part has the notches or grooves o<4>. The valve is normally held off its seat by the pressure of water on the underside of the lower enlargement, and is forced on to its seat by the increased pressure acting on the upper side of the upper enlargement. The high-pressure choker valve P is normally kept on its seat by the liquid pressure, and small notches p<6> allow the passage of liquid. In order to flush the valve passage in the event of the valve becoming clogged, a removable lever Q is provided to force the valve off its seat.
