Title: Improvements in End Play Devices for Rotary Machines.
Filed: 1901-11-19
Granted: 1902-11-19
Abstract: 23,382. British Thomson-Houston Co., [Hewlett, E. M., and Potter, W. B.]. Nov. 19. Converting alternating and direct currents; transformers.-Relates to means for maintaining end play in the shaft of rotary machines, such as converters &c., whereby the grooving of the commutator under the brush tread is avoided. The invention is a device of the type described in Specification No. 1864, A.D. 1900, [Abridgment Class Dynamo-electric generators &c.]. In a box 3, attached to the standard in which the shaft 1 is journalled, slides a disc 4 controlled by a leaf spring 5 and provided with an edge inclined to the end of the shaft. The disc is split and may be clamped in position by a bolt passing through the two jaws. In the disc is mounted a plug 8 carrying, on ball bearings, a spindle 9, to which is rigidly attached a projection 11 forming a bearing for a roller 12. A cylindrical extension 14 of the roller bears on the edge 7 of the disc 4. A steel shoe 15 screwed to the end of the shaft acts as a bearing-surface for the roller. The bias given to the shaft by the magnetic field forces the shaft into contact with the roller when it is in its lowest position. The roller is rotated by the shaft, and travels along the edge of the disc to the upper position shown, forcing the shaft against the action of the field, after which it again drops to the lowest position and the cycle is repeated. The spring 5 assists the roller in giving an outward thrust to the shaft.

Title: Improvements in and relating to the Manufacture of Electric Accumulator Plates.
Filed: 1902-03-14
Granted: 1903-02-05
Abstract: 6304. Accumulator Industries, Ltd., and Hunte, J. J. H. March 14. Secondary batteries.-Relates to the manufacture of plates of the non-pasted type. A current is passed through lead plates arranged as anodes in an electrolyte consisting of a solution of sodium sulphate and sodium chloride or other compounds which will give off chlorine and oxygen, whereby chemical compounds of lead with chlorine and oxygen are formed on the plates. These compounds are then broken down by subjecting the plates, as cathodes, to the action of the current while immersed in the same solution. The plates, which thus become coated with porous layers of reduced lead mixed with some lower oxides of lead, are then washed and "formed" as anodes in dilute sulphuric acid.
Patent GB-190207151-A (GB)
Title: Improvements in Electric Arc Lamps and Inductance Coils
Filed: 1902-03-24
Granted: 1902-09-11
Abstract: 7151. British Thomson-Houston Co., [Fish, W. C.]. March 24. Arc lamps are worked without steadying - resist - ances, and, in order to check oscillation of the moving parts, these are attached to mechanical devices having a natural period of oscillation differing from that of the moving parts. An inductance coil may be used in series with the lamp. In the lamp shown, a clutch 4 is connected by a central tube 3 to the U.shaped core 2 of series solenoids 1, and the core 2 is connected by rods 8, 9 and a crossbar 10 to a dash-pot 12. Small blocks of lead 13 are held between springs and collars on the rods 8, 9 ; the springs may differ, so that the blocks have different oscillation rates. Otherwise, each block may be hung by a single spring from the cross-bar 10. An inductance coil 21, applicable for use with such a lamp, has an iron core carrying an additional coil 22, to which a constant current is supplied through a steadying-resistance 23, the windings 21, 22 being arranged so that their magnetizing-forces are equal and opposite when the normal current is passing through the main coil 21. The core is thus normally unmagnetized. The resistance 23 reduces the currents induced in the coil 22 by changes in the current carried by the main coil 21.

Patent GB-190211614-A (GB)
Title: Improvements in and relating to Gas Meters.
Inventor: BOULT ALFRED JULIUS
Filed: 1902-05-21
Granted: 1903-04-16
Abstract: 11,614. Boult, A. J., [Compagnie pour la Fabrication des Compteurs et Materiel d'Usines Ó Gaz]. May 21. Meters.-The meters are provided with fraudpreventing devices. In the meter shown, the casing 7 is provided with a gas inlet 1, a gas outlet 2, a tube 3 for introducing water, and a water overflow A, and is separated by a partition 8 into two compartments 6, 40. Within the compartment 40 is a rotary measuring-drum 5. Water is contained in each compartment, that in the compartment 40 being maintained constantly at one level. Should, however, the water level in 40 fall abnormally low, a float 9 causes a valve 10 to cut off the admission of gas. The shaft 11 of the drum actuates the registering-mechanism 15 by means of a screw 12, a worm-wheel 13, and a vertical shaft 14. It also actuates a ladle 19, arranged within the supplementary chamber 6, by means of a crank 16, connecting-rod 17, and lever 18. The ladle is balanced by a weight 20, and serves for transfer ring water from the chamber 6 to the chamber 40 at a rate faster than any loss by evaporation. The pivots of this mechanism are arranged to be continually beneath the surface of the water. Back movement of the drum is prevented by a ratchetwheel 21, loose on the shaft 11 and driven by the crank 16, engaging a pin 39 thereon. The ratchetwheel is provided with a pawl 22. The level of the water in the compartment 40 is regulated by an overflow cup 27 and pipe 25, which are carried by a rod 28 secured to the casing. The pipe leads the water back to the compartment 6. The gas passes to the measuring-drum by a bent tube 29. The compartment 6 has a bent overflow pipe 31 leading to the stoppered outlet 4. This pipe is cut off from the gas in the compartment 6 by a plate 33 forming a hydraulic seal, thereby preventing any unmeasured gas from being withdrawn through the tube 31. Should such an attempt be made, however, measured gas will be withdrawn, in consequence of the provision of a small tube 36, opening at its upper end into the compartment 40 above the water level, and at its lower end above the opening of the tube 31. Water is admitted to the compartment 40 through a pipe 37. To prevent unmeasured gas from being withdrawn through this pipe, it is surrounded by a tube 38, forming a water seal, which is closed at the bottom and open at the top to the measured gas compartment. If water is poured into the meter in excess, any siphoning action due to the production of a vacuum is prevented by the fact that the drum can rotate backwards to the extent of almost a whole rotation, that is, until the pin 39 on the ratchet-wheel again engages with the crank 16.
