Patent GB-189709127-A (GB)
Title: Improvements in Electric Meters.
Filed: 1897-04-09
Granted: 1898-03-12
Abstract: 9127. Evershed & Vignoles and Evershed, S. April 9. Magnetically relieving pressure on bearings.-Electric meters are made with magnetically-supported vertical spindles to render the frictional resistance unimportant. The soft iron or steel spindle A carries a brake cylinder R in the fields of symmetrically-fixed permanent magnets B. The inner poles of these are alike and connected by an iron yoke I, which carries a central iron pin N within a bracket Q. A thin metal plate K is clamped to this bracket by a ring V. The ring V surrounds the spindle A to keep it in the magnetic field of the pin N, which thus supports most of the weight of the spindle and keeps it central. The lower end of the spindle is a thin hard steel pin, turning in a jewelled support J. In modifications, the parts I, N are replaced by a vertical bar magnet, independent of the brake magnets. Either permanent or electro magnets may be used. The axle may have a hard steel point at its upper end, and the magnetic attraction be sufficient to hold this up to a flat jewel.

Granted: 1898-04-30
Abstract: 10,778. Thrasher, S. P. April 30. Chronoscopes; electric c l o c k s.- Three drums mounted loosely on a common shaft are provided with numerals similarly arranged to those described in Specification No. 10,770, A.D. 1897. The weighted yoke X is provided with shafts having spring pawls adapted to engage in perforations in the drums. The arrangement of releasing-gear for allowing the second or third drums, or both, to be rotated is the same as that described in the above-quoted Specification. A master clock, not shown, makes and breaks contact every minute, thereby first lifting the lever Y attached to the armature y of the electromagnet D, releasing the rod e and allowing the yoke X to rotate one or more of the drums, and then allowing the levers Y and a to fall and draw down the rod e and return the yoke. Seconds mechanism; dials; hunds.-In Fig. 11<a>, the armature Y is pivoted at Y' and has a pawl T driving the ratchet-wheel 0 fixed to the shaft N, which carries a double cam P and a double pointer Q, the latter like the pointer described in Specification No. 10,770, A.D. 1897. The dial is graduated in subdivisions of five seconds, and the rod e is actuated by the lever a<1> worked from the cam P.

Granted: 1900-03-31
Abstract: 16,056. F r i e d e b e r g e r, L., and "Vulkan" Gesellaschaft f³r selbstz³ndende Gl³hk÷rper. Aug. 5. Lighting gas.-Catalytic igniters which are not hygroscopic, and which do not require special platinum wires or bodies to be embedded therein, are prepared by calcining an intimate mixture of a salt yielding a refractory oxide, a chloride of a metal of the platinum group, a cyanide of a metal of the platinum group, and a chlorine-expelling agent, i.e. a refractory acid or a salt leaving behind such an acid. Preferably, a fabric of cotton, silk, wool, asbestos, or the like is impregnated with a solution of water-glass, dried, and treated with hydrochloric acid, which leaves behind silicic acid in a gelatinous state. The fabric thus silicified is impregnated with a solution containing 25 parts of platinic chloride, 6 parts of barium platinocyanide, and 19 parts of thorium nitrate in 50 parts of water. After drying, the impregnated silicified fabric is cut into pieces and exposed to heat to reduce the salts. The igniting-composition may be obtained as an amorphous mass by mixing the solution of thorium and platinum salts with pure hydrated silicic acid, evaporating to dryness, and calcining the residue. The platinum may be replaced by any metal of the platinum group, or by anv mixture of such metals. Similarly, platinochlorides of thorium, magnesium, and the like may be substituted for platinic chloride, platinocyanides of magnesium, zinc, thorium, and the like for platinocyanide of barium, and nitrates of magresium, zinc, and the like for thorium nitrate. Silicic, hydrofluoric, fluosilicic, boric, phosphoric, and like acids, either as such or in the form of decomposable compounds, may be employed as the chlorine expelling agents.

The flange d has a gap to allow of the screw and nut being lifted out of the base. The top of the base A and the bottom of the flange d have matching irregularities to prevent accidental rotation of the nut. The pivot F fits loosely in a hole in the screw B, and is retained by a lug h engaging an annular recess f with which communicates a vertical groove g to allow of the pivot being lifted out of the screw ; the groove g may be stopped up by a set-screw i, which also serve to clamp the screw B and pivot F together.

Stops x, w limit the tilting of the seat. To control the tilting there is a spring N bearing between the stop wand the head of an adjusting-bar P n. A hand-wheel nut y engages the screw n, and bears against a cross-bar on projecting lugs carried by the lugs k. The surface of the cross-bar and nut y have matching irregularities.

Abstract: 10,244. Robinson, J. H. June 5. Louvred and baffle-plate apparatus.-To obviate the disadvantage of cast air-grate ventilators, in which the inclined cross-bars can only overlap to an extent permitted by the moulding and casting, the cross-bars are constructed separate from the frame, and are afterwards placed in position.
