Title: Improvements of Composite Tubes or Pipes for Conducting Hot or Cold Liquids or Gases or other Substances.
Inventor: WALKER EDWIN
Filed: 1903-11-10
Granted: 1904-09-15
Abstract: 24,355. Walker, E. Nov. 10. Metal pipes and tubes ; spigot-and-socket joints; couplings, disconnectible.-Relates to lining iron, steel, or other metal pipes used for conducting liquids, or gases, with a different metal, so as to permit longitudinal expansion or contraction of the lining independently of that of the pipe. In one method, the lining is in two pieces which overlap each other and are then expanded into position, the ends being flanged back as usual. Another method is shown in Fig. 2, in which the copper or other lining b is expanded at one end into a recess in the pipe alpha, and the other end projects, forming a shaft c, the joint being secured by a nut e. In another modification, the spigot end is reduced to fit into the lining without it being recessed. In the modification, shown in Fig. 4, a short tube or ferrule f, provided with the beading g to prevent it from slipping, overlaps the ends of the lining b.

Patent GB-190415293-A (GB)
Title: Improvements in Calcium Carbide Containers, also applicable as Acetylene Gas Generators
Inventor: LHOSTE FREDERIC AUGUSTE
Filed: 1904-07-08
Granted: 1905-07-08
Abstract: 15,293. Lhoste, F. A. July 8. Acetylene.-A receptacle for holding calcium carbide, which may also be used as an acetylene generator, comprises a body A, Fig. 1, the bottom of which is weighted with ballast B and supports the carbide C. Above this is placed a plug D of some purifying-material, and a perforated tube I serves to connect the inside of the box with the outside. A wide tube E, terminatingin a crosspiece E<1> and per-. forated at F, slightly compresses the plug D, and ends in the top of the box in a screwed fitting G, to which the burner holder H may be connected. On immersing the apparatus in water, the liquid enters by the tube I and attacks the carbide, and the acetylene produced, after being cooled by passing over the walls of the box and purified by contact with the plug D, is burned at the fitting H. In a modified form of the apparatus, a groove J, Fig. 2, is made in the side of the container, and is covered with a plate which leaves a small orifice N at the top so as to form a water channel leading to the tube K, from which the water can escape by the hole L placed between two plates M, M<1> to prevent it from clogging. The apparatus acts as does the one previously described, and the inverted siphon J K serves as a trap and keeps the gas inside under pressure as long as acetylene is being produced. These container generators are thrown away after use.

Title: Improvements in or relating to the Transmission of Power from Internal Combustion Engines.
Inventor: MAYBACH WILHELM
Filed: 1905-11-08
Granted: 1906-05-10
Abstract: 22,947. Maybach, W. Nov. 9, 1904, [date applied for under Patents Act, 1901]. Gas and like engines. - Power is transmitted from the engine by pneumatic means to the axles of road vehicles, propeller shafts of boats, &c. The air-compressor cylinder b mounted between the explosion cylinders b<1> supplies air to compreesedair engines c through a surface apparatus g heated by the exhaust from the explosion engine. The heater is not of sufficient capacity to store air in large quantities. When the load is excessive, as on ascending hills in a motor-car, the explosion engine is enabled to run at its normal speed by throttling the inlet to the compressor which reduces the quantity of air compressed but supplies it at a higher pressure to the more slowly running engines c. These engines are fitted with reversing and variable-expansion valve-gear and drive directly vehicle wheels &c.

Title: An Improved Tension Regulating Device for Loom Beams or Reels.
Inventor: BACON DANIEL
Filed: 1905-11-30
Granted: 1906-03-01
Abstract: 24,861. Bacon, D. Nov. 30. Brakes.-The tension on loom beams or reels A is reduced uniformly as unwinding proceeds, so as to give a uniform let-off and tension. A number of electro-magnets B are arranged at the end of the beam, and by their attraction on the face-plate c produce the necessary drag, which is caused to decrease, as the unwinding proceeds, by increasing the resistance in the energizing-circuit and thus gradually decreasing the current in the electro-magnets. A rheostat having contact-plates 1 of different lengths communicating with resistance coils and wires w, w<1> is used, the current passing through a threaded contact-finger F on a feed-screw g, rotated by worm &c. gearing from a driven part of the loom. The circuit also comprises the wire w<3> and the contact M, by which five independent sources of electric energy or resistance may be thrown into circuit so that the maximum current obtained may be varied. The coils are arranged so that, as the finger F travels, the resistance increases in the required proportion.

Phonographs &c.-A compressed-air enunciator for phonographs, gramophones, &c. consists of a box 4 carrying a valve 8 and supplied with compressed air from a supply tube 1 through a filter 3 consisting of perforated diskf separated by cotton. As a stylus 12 attached to the valve 8 moves up and down, the compressed air flows from the box 4 past the edges 7, 9 forming the valve seating, and through the central passage 14 to the trumpet. Fig. 4 shows a form in which the stylus is attached to a pivoted lever 13 controlled by an adjustable spring 15 to counterbalance the weight of the valve. In another similar form, the box 4 is placed horizontally and provided with a gramophone needle. Fig. 8 shows a form in which the stylus is attached directly to a membrane 27, the air passing through slots 25 and expanding in parallel slots 28, thence escaping through holes 29 to the trumpet 31. In another form, the valve 8, Fig. 1, may be replaced by the membrane. In the form shown in Fig. 11, the membrane rests against radial slots 32, the air expanding in intermediate grooves 34 and escaping through a central opening 33. In a last modification, the membrane rests against holes in projections. Specification No. 10,468, A.D. 1903, is referred to.

Abstract: 3183. Hazlehurst, A. H. Feb. 8. Door closing and opening apparatus.-Relates to self-closing double swing doors for lift shafts &c., and to means for retaining them in an open or closed position. A bracket a fixed to one half p<1> of the door is provided with an arm connected by a rod g to a bracket f on the other half p. Through the bracket a in alinement with the door hinges is inserted a spindle c connected at its slotted extremity to the free end of a spring d, the other end of which is secured to a slotted spindle e fixed on the door frame q<1>. When the doors are opened, the torsion of the spring, which is adjusted in known manner, effects the closing operation. In order to retain the doors fully or partly open during the presence of the lift cage n, the door p<1> is provided with a ratchet segment r, Fig. 10, adapted to be engaged by the usual spring pawl carried on a bar j which is slid forward in its guides by a cam o on the cage n.
