Granted: 1906-03-08
Abstract: 18,037. Poulsen, V. Sept. 17, 1904, [date applied for under Patents Act, 1901]. Telegraphs. - In wireless signalling-systems in which a constantly energized transmitter is used, resonance is obtained in the receiving-system by intermittently connecting the wave - responsive device to the antenna circuit. In the arrangement shown in Fig. 1, one pole b of the coherer I is alternately brought in contact with the terminals e, f of the antenna and relay circuits respectively. The antenna circuit may be connected to the coherer through a transformer, the coils a, l, Fig. 6, of which are conductively connected. In this arrangement, the pole c of the coherer is brought into contact with the contact m when the pole b is in contact with f. Fig. 7 shows the receiving-coil a combined with a magnetic-detector system, intermittent contact being effected between the points b, e. The arrow indicates the magnetized core of the magnetic detector. The intermittent contact may be effected by vibrating wires, tuning-forks, revolving interrupters, &c.

Abstract: 10,152. Hollingworth, E., [Crompton & Knowles Loom Works]. May 1. Looms, checking shuttles in ; swells.-Relates to a device, for use with change-boxes, for holding the shuttles firmly in the boxes which are not in use. The ordinary binders 8, in addition to being acted on by their usual springs, are acted on by spring- pressed pushers 18 fitting through apertures in a plate 13, which is bolted to an angle-plate 15 bolted to the underside of the shuttle box. The plate 13 moves with the shuttle boxes, and the pushers acting on the binders keep the shuttles firmly in position. To release the binder acting on the shuttle in operation from the action of the pusher, so that it may act in the usual manner in connexion with the protector mechanism, the pushers are provided with outer ends or heads 18<1> having vertically-extending bevelled edges 18<11>. A stationary plate 20 is provided with two vertically-extending engaging portions 20<1> haying bevelled undercut portions, which extend under and engage the bevelled surfaces 18<11> of the pusher in the shuttle box in line with the race, pushing it outwards against the action of the spring 19. The releasing- plate 20 may be supported on the upper offset end of an arm, the hub of which is loosely mounted on the outer end of the rock-shaft of the protector mechanism.

Title: Improvements in Filters.
Inventor: BURT EDWIN
Filed: 1906-10-08
Granted: 1907-04-25
Abstract: 22,187. Burt, E. Oct. 8. Bag filters; pressure filters; discharging solid matter.-Ore slimes are supplied under pressure to the filter 5 by means of a pipe 36, flexible connexion 38, and a perforated pipe 32 which extends the length of the filter cylinder. The solid matter forms cakes upon the bags 14, from the interior of which the filtered solution passes to the discharge pipe 21 through curved perforated collectors 17, Fig. 4, and pipes 20. The bags are of canvas and envelop cores of wire mesh which form hinge-like joints at their upper ends so that the bags can swing freely. After cakes of the desired thickness have been formed, unfiltered slime is forced out through the pipes 32, 34 by compressed air admitted through the pipe 44. Wash water is then admitted through the pipes 42, 38, 32, and passes through the cakes to the pipe 21. The cakes may be dried by again admitting compressed air through the pipe 44. The cylinder is then tilted about trunnions journaled in blocks 3, and steam, air, or water is passed through the pipe 21 to remove the cakes, which fall through the door 24. The cylinder may be tilted by means of a piston 9 working in a case 7 pivoted at its lower end. There is an additional air - supply pipe 40.

The amount of steam passing to the heater is regulated by a flap valve v. The exhaust steam passes downwards through tubes n, and the condensed steam is removed through a pipe t, which may be provided with a steam trap. The feed-water passes around the tubes n, being admitted to the casing k through an opening r. The beater may be so constructed that the exhaust steam passes outside the tubes n. An ejector may be provided for each of the cylinders of the locomotive, the heater being supplied from one or both exhausts.

Title: Improvements in and relating to the Extraction of Metals from Ores.
Inventor: FERNAU JOHN JAMES CONSTANT
Filed: 1906-11-06
Granted: 1907-08-29
Abstract: 24,905. Fernau, J. J. C. Nov. 6. Metallurgical furnaces.-In apparatus for extracting zinc, and other metals generally associated with zinc ores, such as lead and silver, by treating the ores in a moving bath of molten iron or other metal, the iron is continuously run out from the furnace or vessel in which the ore is treated and passed through a superheater in which it is blown up with fuel to raise the temperature considerably above the melting-point before passing back into the furnace. In one arrangement of apparatus, the superheater A, Fig. 1, is in the form of a stationary Bessemer converter, fuel being introduced with the blast. The molten iron flows through a trough F to a well G and thence through a submerged opening H to the reduction chamber B, over which is the shaft C through which the ore is supplied. The iron flows off through openings L into transferrers M, Figs. 1 and 4, which can be tilted by chains N to run their contents back into the superheater. The transferrers are operated alternately. The iron sulphide and slag formed are tapped off periodically through an opening P, Fig. 1. Metal that sinks to the bottom of the bath is tapped off through a hole Q. A chamber R is filled with coke, kept incandescent by the bath, which reduces any zinc oxide formed. The chamber is connected with the shaft C by passages S which allow any zinc vapours arising in the shaft to pass to the chamber R and so to the condenser T. In a modification, the reheating of the metal is carried out in a regenerative reverberatory furnace e, Fig. 5, from which the molten metal passes over an arch f to an intermediate chamber connected by a submerged passage h with the reducing-chamber i. The exit opening n for the iron connects with a passageway leading to the superheater, the passageway being provided with a water-cooled paddle driven at a suitable speed to cause the desired circulation of molten metal.

Abstract: 1250. Chivers, C. Jan. 17. Bookbinding.--In rebinding old books, the sections a are pasted and sewn to a headband c of any material, preferably thin leather, and flaps f are left at the ends and are afterwards secured to the end papers and covers of the book. The edge of the head-band c may be turned over, as shown. The preferred method of sewing is as follows :-The end of the thread is fastened by means of a knot between the middle leaves of the end signature at or about the end stitch of the original sewing of the book. The thread is passed through signature and head-band and over the edge of the signature to its starting point; again through the back of the signature and up to the top edge, where it is looped through the first turn, and then carriei to the next signature. It is then passed from inside to outside and up to the top edge of the second signature and looped over to the next signature, and so on, to the last one, where it is fastened off with a double turn as at the first. Additional bands may be used between the top and bottom edges of the book.

Abstract: 4387. Court, C. L., and Duggan, T. F. Feb. 22. Scoring and marking.- Relates to a billiard marker of the type in which a device is employed to register the number of games which have been played. The indicator consists of a casing a, upper and lower numbered rollers c, d, and the usual pointers(not shown). The upper roller is freely rotatable, but the lower roller can only be rotated by means of a removable knob to be carried by the attendant. At the top of the casing is a compartment with an inclined floor a<2>, having at its lower end an opening communicating with a tube e, the lower end of which abuts against the end d' of the roller d. A pocket d' in the end of the roller comes opposite the lower end of the tube when the roller is rotated. Backward rotation of the roller is prevented by means of a ratchet-and-pawl mechanism h, h<1>. In use, a number of small steel balls f are placed on the floor a<2>, from which they pass into the tube e. As the pocket d<4> passes the end of the tube, a ball falls into it, and when the roller is further rotated, the ball falls into a drawer g in the base of the indicator.
