Title: Improvements in Turbine Water Wheels and in Governors therefor
Inventor: ELLICOTT FRANCIS
Filed: 1900-12-24
Granted: 1902-01-24
Abstract: 23,562. Ellicott, F. Dec. 24. Centrifugal and inertia governors; fluid governors.-Relates to the regulation of a water turbine of the inward-flow type, shown in half sectional elevation in Fig. 1. A cylindrical gate 40 surrounds the wheel, and controls the water supply. One form of governor for controlling the gate is shown in Fig. 1. The gate 40 is supported by rods 45 from a ring piston 59, which works in an annular chamber 58. The chamber is open at both ends to the penstock water, while the centrifugal pump 55 forces water through a valve-controlled pipe 63 to the lower end of the chamber. The upper end of the chamber is connected by a pipe 65 to the waste, and for any particular outflow opening the speed of the pump increases until the pressure under the annular piston is sufficient to raise the gate and adjust the inflow. A modified form of governor has a tubular D-valve 250. Fig. 15, which is controlled by a suitable governor and which regulates the supply of penstock water to the under side of the annular piston 59. A centrifugal governor adapted for actuating the D-valve is shown in Fig. 18. A nut 17 and screwed sleeve 107 are connected by a coiled or other suitable spring 118, and slide on a feather on a sleeve 103 fixed to the driving-shaft 3. A flywheel 122 is carried by a sleeve 119 on the shaft, and is connected to the nut by weighted arms 124, the centrifugal action of which is balanced by the spring 128. The valve rod 115 is connected to a pivoted lever 113, which engages with the sliding sleeve 103. When the speed of the turbine increases, the screwed sleeve turns inside its nut, and the valve rod is raised. The tension in the spring then overcomes the inertia of the moving parts, and the governor readjusts itself. Over-sensitiveness is guarded against by the spring 128, which is first compressed by the chair 127, and then lifts the flywheel by means of a sleeve 130.

Patent GB-190119527-A (GB)
Title: Improvements in the Manufacture of Borax
Inventor: HARGREAVES JOHN
Filed: 1901-10-01
Granted: 1902-09-25
Abstract: 19,527. Hargreaves, J. Oct. 1. Borax is obtained from boron compounds, such as crude calcium borate, by (1) systematically treating it in a series of vessels with sodium carbonate in solution, (2) mixing the borate with the carbonate and only sufficient water to form a semiliquid mass and subsequently lixiviating, or (3) mixing the borate with a sodium carbonate in a crystalline condition or in a condition of a saturated or supersaturated solution. For the first method, a series of six vessels a, b, c, d, e, j is employed, each vessel having an agitator, and holes h leading to a main tube i. The latter is connected with a crystallizer p, and also with an injector m for driving the mother liquor to a trough k for refeeding it to the vessels. Each vessel is also provided with steam heating-tubes. Each vessel is in turn emptied and refilled, and becomes the first, intermediate, or last of the series. Powdered calcium borate is charged, for example, into the vessel a, in which is a solution of sodium carbonate, or which contains a solution from the vessel b, further sodium carbonate being added, if necessary. The solution is then boiled. After a time, washing - liquor from other vessels is added. The strong solution obtained is run off into the crystallizer p. A new vessel, viz., j, is now added as No. 1 of the series, while a becomes the second, and a fresh supply of carbonate, together with more washing-liquor, is added to a. The contents are again boiled, the solution obtained being run into the new first vessel j. In the next step, the washing-liquor from b is passed to a, and that from c to b, while the vessel d is being emptied and recharged, and e is the first vessel of the series. In the next step, a receives washing-liquor from b, c being now emptied. Afterwards a is the last washing-vessel, and is, in the next stage, emptied and refilled. The washing-liquor obtained from each vessel is thus led in each case to the vessel next highest in the series. The mother liquor from the crystallizer is further treated by refrigeration to obtain more borax crystals. For the second method, the powdered crude borate is mixed in a mixer with sodium carbonate, and with water in a quantity sufficient to form a soft mass when hot. The reaction proceeds throughout the mass, and becomes complete before the mass sets hard on cooling. The borax is then systematically lixiviated out. For the third method, instead of allowing the mass as in the second method to set, it may be kept hot by imparted heat, or it may be agitated without imparted heat, or it may be both heated and agitated until the reaction is complete. In each case, calcium carbonate is obtained as a bye-product. Sodium carbonates.-Sesquicarbonate or bicarbonate of soda for use in this process may be obtained by passing carbonic acid from any source, such as the exhaust of a gas engine, into and through monocarbonate.

Patent GB-190210407-A (GB)
Title: An Improved Apparatus for Applying and Affixing Postage and like Stamps to Envelopes, Post-cards, and other Articles.
Inventor: TURNER JOHN ROBERT
Filed: 1902-05-06
Granted: 1902-10-02
Abstract: 10,407. Turner, J. R., and Stimpson, M. May 6. Damping and affixing stamps and the like. - By a single manual operation, the apparatus lifts a stamp from a magazine, passes it over a moistener, applies it to an envelope, postcard, &c., and there presses it. In Fig. 3, the operative parts are shown in the position assumed when a stamp has been applied and affixed, the parts being enclosed in a casing mounted upon a base. The bottom plate of the casing is provided with three apertures, beneath the first of which a' the stamp-magazine appears, and beneath the second a<2> the moistening- device, while the third aperture a<3> permits the passage of the stamp to the envelope, which is inserted in the gap x between the bottom of the casing and the baseboard. The telescopically-acting, spring-returned stamp lifter carries at its lower end a pair of pads charged with an adhesive medium, so that it may lift on each occasion a single stamp and present it to the jaws of the gripper 7, which has been advanced for this purpose. The gripper carries the stamp below the curved plate 13 and over the pad 11, where it is moistened. On a further retreat of the gripper, the presser-block n is depressed and brought to bear upon the stamp, which has been laid by the gripper, above the envelope. The presser consists of a face of resilient material through which a piston r controlled by a spring is adapted to work. Its function is to hold the stamp on the envelope and prevent it from being dragged away by the gripper when the gripper is completing its retrogression. The gripper consists of a sliding plate v moving in guide-ways and provided with jaws x<1>, the lower of which is formed conveniently in one piece with the plate, while the upper one is held closed normally by a spring. The upper jaw is fitted with a crossrod which rides up inclined blade springs 8, and thus causes the gripper to open as it advances towards a stamp. When the stamp is seized, the cross-rod has passed beyond the end of the springs 8, and has thus allowed the spring of the gripper to act and close the jaws, the pressure of the spring being such as to allow the jaws to release the stamp only when the piston r is bearing upon it. The various actions are effected by the depression of a knob, the rod l of which is connected by links j, to the parts of the apparatus to be set in motion to effect the object of the invention. To permit letters or packets of varying thicknesses to be inserted in the gap between the casing and the base, one or more detachable boards are slid in or out of the gap as required.
