Title: Improvements in Pneumatic Rubber Structures, specially Applicable to Pneumatic Rubber Tyres, and in Apparatus for the Manufacture thereof.
Inventor: VERNON THOMAS THORNYCROFT
Filed: 1903-07-18
Granted: 1904-06-30
Abstract: 15,913. Vernon, T. T. July 18. Tyres, pneumatic.-A pneumatic multi-cellular tyre is made by lapping together perforated or recessed strips of rubber or other materials, with or without intermediate unperforatod strips, in a closed vessel containing air or gas under pressure, and uniting the strips by cementing or vulcanizing, or both, so that the compressed air or gas is retained in the cavities in the structure. Fig. 4 shows a strip made up of a perforated rubber strip 1, a canvas band 3, and a rubber strip 2, which may also be perforated. Fig. 5 shows a combination of perforated and plain rubber strips. In other forms, several strips are combined so that the perforations or indentations do not coincide, and the strips may be bound together by flexible ties or circumferential bindings. The rubber strips 1, 2 may each be made up of canvas, woven wire, or like fabric, with a layer of rubber on each side. The strip is placed in a box 7, Fig. 1, and is led between the pressing-roller 10 and a tension roller 9, and thence to rollers 11, 12. The roller 11 runs in a tank 21 of a suitable adhesive solution, and the roller 12 is provided with means to adjust its pressure on the strip 8, or is placed in contact with the roller 11, and used in a manner like that followed in inking printing-rollers to determine the consistency of the solution. The strip is attached to the periphery of the rotary mould 13, which may be replaced by the wheel rim, and may be fitted with a pressing-roller 28. The box being closed, air &c. under pressure is admitted through the pipe 25, and the mould 13 is rotated until the strip is wound upon it. The first and last layer of the strip should be unperforated, or the last layer may consist of a band of steel, by means of which a great circumferential tension may be obtained. When the strip is wound, the sides of the mould 13 may be forced towards each other. Steam may then be admitted to the box or to a jacket on the box through the pipe 30 to vulcanize the rubber. According to the Provisional Specification, the gas may be generated in the cavities by placing in them substances which will gasify at the vulcanizing temperature and remain fixed.

Title: An Improved Machine for Labelling Bottles Boxes, or other similar Receptacles.
Inventor: BLUME MARGARETHE
Filed: 1903-09-04
Granted: 1903-10-29
Abstract: 19,038. Blume, M. Sept. 4. Affixing labels.- Consists of a machine for gumming labels and affixing them to bottles, boxes, and other receptacles. A bottle 33 is inserted in the machine by lifting a roller 31 through a pedal 34 and link 35. On pulling a lever 38 over to the left by hand, or by a treadle arrangement, a shaft 9 is driven through a chain connection with a wheel 37 on the lever axis. This movement of the shaft 9 causes a cam-disc 12, Fig. 3, upon its axis to depress a link 13 by means of a roller 14, and so rotates a pair of pivoted levers 17, 20 clockwise. A roller 21, disposed beneath a table 23 sliding upon rods 22, is engaged by the lever 20, and a label, placed on the edge of this table is delivered into a slot 7 aud partly on to an india-rubber gumming-roller 6 bv the movement of the table. By this time, the rotation of the shaft 9 has brought india-rubber or other flexible interchangeable moulds 10, fixed upon the shaft 9 by a detachable socket, on to the roller 6, where they grip the label and pass it over a comb 8 to a shaft 26. The label has been gummed upon its under surface during this process, for the friction between the mould 10 and the loose roller 6 has caused the latter to rotate, driving by friction a roller 5 working in a gumming-trough. The shaft 26 presses the label upon the bottle, and, on pressing the pedal 34, the roller 31 rises again, allowing the bottle to slide out along an inclined plane 36. A fresh bottle is introduced and the operation repeated, for the semicircular portion of the cam-disc ceased to engage the roller 14 before the label was carried from the shaft 6 over the comb 8, thus allowing the link 13 to move upwards into its original position, to which it is restored by the table 23 sliding down to its lowest position by its own weight. To ensure the labels being stuck in the same manner and upon the same portion of the bottle, adjustable laths 24 are provided on the table, to correspond with the different shaped moulds 10 used for different shaped labels. The spindles of the shafts 25, 31 carry equi-sized chainwheels, which are connected. A chain also passes over the wheel 25, on shaft 26, over a tensionwheel 27 of the same size, and over a wheel 16 on the spindle of shaft 9, this latter wheel being twice the size of each of the others, the rollers 26, 31 consequently completing two revolutions for each one of the shaft 9.

Title: Manufacture of New Dyestuffs of the Anthracene Series.
Inventor: IMRAY OLIVER
Filed: 1904-07-04
Granted: 1905-05-04
Abstract: 14,970. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. July 4. Dyes, artificial.-Oxazine dyes of the anthracene series such as. cannot be made by condensing alizarin with orthoamidophenols. According to the present invention, condensation can be effected if, instead of alizarin, the derivatives of alizarin containing a hydroxyl or amido group in the 4-position are used. The hydrogen of the amido group may be substituted by an alkyl or aryl group. In the.same way, the alizarin derivatives will condense with orthodiamines to give diazines, such as where R is the hydroxyl or amido group above mentioned. Three examples are given. In example 1, purpurin, ortho-amido-phenol, boric acid, and alcohol are heated to 140‹ C. under pressure for several hours. The liquid is then filtered cold and the insoluble oxazine is then crystallized from hot pyridine in violet needles. This dye when suspended in boiling alcohol and treated with caustic soda yields a pure blue solution of the sodium salt, which may be sulphonated in the usual way, yielding a sulphonic acid which dyes wool blue-violet without a mordant. Instead of purpurin, 1 :2 : 4- amidoalizarin or one of its derivatives, such as dimethylamidoalizarin or 1 : 2 : 4 - anilidoalizarin may be used. In example 2, sodium purpurin-3- sulphonate, orthoamidophenol, boric acid, and water are heated to 140‹ C., exactly as in example 1. The precipitate is filtered when cold, washed with dilute sodium carbonate, and purified by dissolving in water and precipitating by adding common salt. It is a blue dye, and will dye wool with a chrome mordant or without mordant. Purpurinsulphonic acids with the sulphonic group in the non-hydroxylated nucleus may also be used, and orthoamido-phenol may be replaced by its halogen derivatives or homologues, such as amido cresol (CH3 : NH2 : OH = 1 : 3 : 4). In example 3, purpurin, boric acid, orthoamidodiphenylamine and alcohol are heated as above, and the dye is separated as in example 1. Orthophenylenediamine may be substituted for orthoamidodiphenylamine.

Patent GB-190421144-A (GB)
Title: Improvements in Electric Lighting of Trains.
Inventor: LEITNER HENRY
Filed: 1904-10-01
Granted: 1905-08-31
Abstract: 21,144. Leitner, H., and Lucas, R. N. Oct. 1. Dynamos, regulating.- The output of a generator in a system of electric lighting for trains is reduced when the batteries are fully charged, by the movement of a small H-armature in the circuit of the main dynamo which short-circuits a lamp in the field circuit of the demagnetizing- dynamo described in Specification No. 23,066, A.D. 1902, and visually indicates the new state of affairs. The demagnetizing-dynamo referred to weakens the field of the main generator when the speed of the train increases, and thereby maintains constant the voltage generated. In order to reduce the output of the generator when the batteries are fully charged, the device shown in Fig. 2 is used in connection with the system tiescribed in the above-mentioned Specification. A simple H-armature a, Fig. 2, is balanced in a two-pole field b, and the windings of the field and the armature are included in the circuit of the main dynamo. Upon the shaft c, Fig. 1, of this armature is keyed the cam d, provided with the contact e and with the nose f. To the armature is connected the arm g attached to the spring h, so that the armature is held normally in the position in which it is least affected by the magnetic field. The field and the armature of the apparatus are so wound and arranged that, when the battery I is not fully charged, no movement is imparted to the armature a, but, when fully charged, the armature is moved so as to close the contact e, j, short-circuiting the carbon lamp resistance G in series with the shunt field winding B of the demagnetizing-dynamo. This reduces the output of the main dynamo. If any of the battery connections are broken, the voltage of the main generator rises, and the armature a is pulled round until the spring-pressed pawl k slips over the edge of the cam nose f, thereby breaking the shunt field winding A of the main generator, and displaying the "out of order" signal. This state of affairs is maintained until the broken contact has been rectified. A reverse winding q on the field of the H-armature is placed in the circuit which supplies current to the lamps. When the lamps are turned on, the field of the armature a is diminished or destroyed, and the armature a returns to its zero position under the action of the spring h, thus bringing the output of the main generator back to its original value.

Abstract: 23,363. Peard, O. L. Oct. 29. Slide rules.-Arrangements of slide rules with logarithmic scales are described for calculating the following quantities:- (1) Loss of heat in waste furnace gases expressed in percentage of normal coal, or British thermal units, from the temperature of and percentage of carbon dioxide in the flue gases ; (2) heat transmitted to water and steam, or thermal efficiency from feedwater temperature and weight of water evaporated per pound of coal burnt; (3) kilowatts from amperes and volts. Fig. 4 shows a section through a circular form in which one datum scale is on the disc A attached to the upper rotatable glass cover E, and the other upon the upper side B of a ring attached to the lower cover E'. Below this ring is the result scale D, which is read against a pointer C upon the central disc. In a modification, all the scales may be read from one side, the scales B, D being upon the same side and the reading-point moving with the scale A. This form may be arranged for a double calculator, as in Fig. 8, where the central disc F turns with the top-plate E and rim J, while the ring G moves with the lower ring J<1>, scales being provided both above and below. Fig. 10 shows a band arrangement for use when one of the datum scales is much shorter than the other, the long scale being placed on a band H, which also carries the result scale and is controlled by a hand-driven pulley G<1> and a tension pulley i, so as to display the quantities through suitable windows, one of which is marked for the second datum scale and the other has the reading-pointer. Alternatively, the long scales may be put on a drum, or upon a rod with the short scale and reading-point upon a slider.

Abstract: 24,915. Highfield, J. S. Nov. 16. Electromagnets; armatures; field magnets.-Air is excluded from high-tension windings by immersion in pitch or like insulating-material and filling the spice between the coils and their cores with suitable insulating-material. Where the metals of the coils and cores have the same coefficient of expansion from rise of temperature, the coils are suspended upon the cores, the space between being filled with a mixture of sulphur and powdered g'ass &c. ; where the coefficients differ, the insulating-material next the coils and cores must be fluid or elastic. In braided coils the spaces are filled with pitch or other similar substance after the coils have been dried in vacuo. A porcelain or mica tube may be used outside the pitch, or tape impregnated with pitch or insulating-varnish &c. The coil is put in position on the core over a layer of pitch, and the spaces filled up with a hard insulating-material such as sulphur and powdered glass, pitch and sand, powdered slate or powdered glass, or similar powdered mineral matter. The ends of the coils are preferably filled up with pitch. Spun glass or other mineral substance may be used instead of braid, the coil being made up with pitch &c. as before to prevent the presence of any air spaces.
