Title: Improvements in or relating to the Detection of Electrical Oscillations.
Inventor: WALTER LOUIS HEATHCOTE
Filed: 1902-10-02
Granted: 1903-06-11
Abstract: 21,462. Walter, L. H., and Ewing, J. A. Oct. 2. Telegraphs.- Relates to a wave detector for use in detecting electric oscillations, such as occur in wireless telegraphy, and depends on the principle that the hysteresis o f a piece of iron is changed by the action of electric waves. In one form of the apparatus, the hysteresis is increased by the electric waves. This apparatus is shown in Fig. 1. A quantity of steel wire J is wound on a bobbin, which is pivoted on a vertical axis and controlled by a spring M. An electromagnet A is rotated on a vertical axis F round the wire on the bobbin, thus magnetizing and demagnetizing the wire on the bobbin, and producing a deflection, as in the apparatus described in Specification No. 2308, A.D. 1895, [Abridgment Class Electricity, Measuring &c.]. When electric waves are passed through the wire on the bobbin, the hysteresis is increased, and consequently the deflection is increased, whereby the presence of oscillations is indicated by a pointer, siphon recorder, or the like. In another form of the apparatus, the hysteresis of a pivoted ring of iron J<3>, Fig. 8, is reduced by passing the electric waves through coils J<4> on the ring. The pole-pieces A' of an electromagnet are rotated round the ring. The deflection of the index on the ring is, in this case, diminished when electric waves are passing. Two coils may be mounted on the same axis, acted upon by electromagnets rotating in opposite directions. The electric waves disturb the balance, and cause a deflection. Various ways of winding the coils of steel wire in the first type of apparatus are described. The apparatus may be arranged so that the magnet is deflected and the coil rotates.

Abstract: 16,287. Howard, J. E. July 23. Rock drills.-A reciprocating pneumatic engine applicable to rock drills &c. contains a piston valve f in the piston-rod d working between fixed tappets. Air is admitted through the handle a' to a chamber c, and acts upon the annular surface of the piston-rod d, Fig. 2, and drives it to the left, the air meanwhile escaping from the left end of the cylinder through passages e', e<2>, e<4> in the piston and rod, f<1> in the valve, and g in the cylinder. The valve is carried with the piston by friction, but is arrested before the piston by a tappet h<2>, thus opening the port e' in the piston-rod to the interior of the valve and admitting air to the left end of the cylinder, when the piston is returned against the pressure on its rod d. The valve is next arrested by the tappet h<1> which serves to throttle the air passage through the piston-rod. The valve may have ends of slightly different area, or it may be constructed as shown in Fig. 6, the head l being arrested by entering the air passage c<1> and by stops l' engaging the diaphragm a<2>. It is packed by split rings k and these may be distended to keep the friction uniform by a spring-pressed cone k<2>, Fig. 4. The piston-rod gland i<2> and the joint between the cylinder a and handle a<1> are prevented from screwing by fixing to them rings m, m<1> having longitudinal notches to receive a key m' which is secured by a sleeve n prevented from revolving by a key o. One ring has one more notch than the other to provide for a fine adjustment. The apparatus has an additional handle p.

Title: Improvements in and relating to Apparatus for Purifying Water
Inventor: DECLERCO ERNEST
Filed: 1903-11-03
Granted: 1904-10-06
Abstract: 23,837. Declercq, E. May 15, [date applied for under Patents Act, A.D. 1901]. Sliding valves; float valves; multiple-way valves. -In an installation for purifying water, the discharge through the partial passages of the slit 12, Fig. 3, is regulated by the slide 14. In the soda distributer d, Figs. 5 and 6, the vessel 42 discharges soda lye at the same rate as water is supplied to the vessel 46, of equal size, by the conduit 4. When the vessel 42 is empty, the requisite quantity of sodium carbonate is added to the vessel 46, and the action is reversed by turning the three-way cocks, Fig. 7, through 120‹. The valve 43 is actuated by the chain 49, which is stretched by the weight 50 and is attached to the chain 47 and passes over a movable roller 52. When the chain 47 connecting the floats 44, 45 slackens, the valve 43 is opened by the stop 53. Closure is effected by the weight 55. When the water in the vessel 75 rises owing to the choking of the filter 78, it fills the box 88 and lifts the float 93, closing the valve 11 and opening a drain valve. The water in the vat a then rises, flows through the siphon 87 into the chamber 79, and up through the filter. When the level in the vat a falls, the plunger 83 emerges and opens the valve 81, so that the filtered water of the vessel 98 flows into the chamber 79 and washes the filter for a second time. The plunger 91 finally emerges and, by means of the device 90, allows the box 88 to empty. The valve 93 then falls, lifts the valve 11, and closes the valve 96, and the normal action of the apparatus takes place once more.

Title: Improvements in or relating to Gas Producers
Inventor: DESCHAMPS JULES-JEAN
Filed: 1904-05-30
Granted: 1904-08-25
Abstract: 12,221. Deschamps, J. May 30. Gas-producers.-Suction gas-producers working with a down-draught are surmounted by a tuyerebox or air casing C, Fig. 1, having, a removable cover A. By this means, the tuyere T, which is simply supported in the protecting-sleeve H by a flange at the top, can be replaced readily by a new one. To enable the volatile matters collecting in the top of the producer to be drawn into the fire with the blast, perforations are formed in the sleeve and tuyÞre, or in the lower part of the casing C, when the latter projects into the producer. as shown by the dotted lines Z, W; or, where the sleeve H is omitted, the bottom S of the casing C may be notched or corrugated to form openings, as indicated in Fig. 2. The tuyere may be entirely of refractory material with single or double walls, or of mild steel or iron protected by water circulation. Fig. 3 shows a metal tuyÞre with a removable refractory lining M. An internal sleeve 0 and shoulder N prevent damage from the stirring or poking rods. For large producers, several tuyÞres of square or oblong section are employed. These are grouped in pairs, which are placed in cells in the top of the producer. There may be one tuyÞre-box common to several cells, as shown in Fig. 4, or several boxes in one cell, as in Fig. 5. To prevent the fuel from being hung up between the tuyÞres, the latter may be fitted with a concentric inner tube through which fuel is fed automatically. Liquid fuel, blast-furnace gases, noxious gases, &c. may be conveyed into the fire in a similar manner. The inner tube is perforated to allow the volatile matters from the charge to mix with the blast, and, by continuing it downwards to the-bottom of the producer, it may be utilized as a coking-chamber. Several inner tubes, serving alternately for air and fuel, may be fitted. In some cases, however, the fuel is fed directly into the tuyÞre with the air.
