Title: Improvements in or relating to Incubators.
Inventor: WILLCOCKS JOHN
Filed: 1898-09-20
Granted: 1899-09-20
Abstract: 19,898. Willcocks, J., and Smith, J. M. Sept. 20. Incubators.-Consists in providing a temperature-regulating device; in moistening the heated air, and in apparatus for turning the eggs. A metal frame B, fixed inside the casing A, carries india - rubber coated rollers C, secured to ends of which are pinions engaging a.rack C', which may be operated through a handle D. The eggs C<3> are placed upon the rollers, and by operating the rack the eggs may be turned over. Instead of a rack, chain &c. gearing may be used, and in the Provisional Specification a quadrant gearing is also described. A water tank F is placed beneath the rollers, and is fitted with suitable supply, overflow, and exhaust pipes and cocks. Above the tank is a perforated zinc or gauze sheet G, upon which rests a flannel sheet H. Air passes through the mushroom valves E, and becomes charged with moisture before passing into the incubator chamber. Transparent doors K are hinged on a level with the frame B, so that the process of incubation may be watched from the outside. The top of the chamber is formed by a heating-tank J, within which is a coil or coils M to conduct heated air from the hood m, situated over an oil lamp or gas jet, to the ventilating-tube P. The hood m is surrounded by a circulating cylinder N and a suitable cover. The tank J is supplied with water through a pipe j. The temperature-regulating device consists of electromagnets R, placed in circuit with a battery, which are adapted to operate levers or rods S', T, T', carrying dampers U, U<1> which normally close the tubes V, V<1> communicating with the incubator chamber, and also close a passage to the hood m. When the circuit is closed, the magnets lift the dampers and allow the heated air to escape, thereby cooling the chamber. Two devices are shown to close the circuit when a predetermined temperature has been reached. In one case, a mercury thermometer Q is employed in which the mercury makes contact with the battery lead when the limiting temperature is reached. The other device consists of an expansible spring or joint Q<4>, provided with a terminal Q<3> which makes contact with a strip attached to the battery lead at the limiting temperature and so closes the circuit. The spring Q<4> is adjusted to the required temperature by means of a spring Q<5> attached to an adjusting-screw.

Title: An Improved Method of and Apparatus for Obtaining High Temperatures for Smelting Metals and other like purposes.
Inventor: BORCHERS WILHELM
Filed: 1899-03-20
Granted: 1899-05-13
Abstract: 6060. Borchers, W. March 20. Metallurgical &c. furnaces.-Relates to a method of, and apparatus for, obtaining high temperatures for smelting metals and other like purposes. Heat is produced by the combustion of solid fuel alternately in one of two chambers, or in one of two groups of chambers, while the fuel in the other chamber or group of chambers is heated by the escaping gases. The combustion is only carried so far as to produce carbonic oxide, so as to enable temperatures to be obtained higher than those at which carbonic dioxide and water are dissociated. Oxygen, or air charged with oxygen, may be used to support combustion, and it may be heated and compressed before use. Fig. 1 shows, in section, a furnace arranged to carry out the process. Two shafts or chambers o', o<2> serve alternately for combustion and for the preliminary heating of the fuel. The material to be treated is placed in the central shaft g, and the product collects at u, whence it may be discharged into the receptacle k. The shafts o' and o<2> are provided with charging- hoppers t with valved lids, and from their upper portions pipes, not shown, lead to a main escape flue, a three-way reversing-valve being fitted at the junction. In starting the furnace, the chambers o' and o<2> are both partly or entirely filled with fuel, and the valves of the hopper lids are opened. The fuel is then ignited at the apertures x, x. When the lower layers of fuel become incandescent, the chambers are filled up with fuel, and the material is charged into the shaft g. The valves in the hopper lids and the ignition apertures are closed, and air and oxygen is delivered to one chamber through one of the blast nozzles d, while the other chamber is put into communication with the gas escape flue by means of the three-way valve. After a time, the three-way valve is reversed, and the air or oxygen is delivered through the other nozzle. The apertures x serve also for the withdrawal of the ash in a molten state; they are closed by weighted plugs as shown. Cooling-passages are formed in the furnace as shown at l.

Abstract: 6731. Melhuish, A. G. March 28. Tapping; screwing.-A machine for tapping or screwing small articles, such as nuts, washer discs, collars, sockets, &c., is shown as applied to tapping nuts. The tap G is carried by a spindle D on which is freely mounted a cone F, constantly driven in one direction from a shaft C. Pins R, carrying sleeves on which are pinions S, Q, are mounted inside the drum, the pinions S gearing with a coned wheel N keyed on the spindle, while the pinions Q gear with a doubleconed wheel M free on the spindle. The wheel M can be moved along the spindle by a lever I and rack T engaging a pinion U, which also moves the work table W. The nuts are supplied from a shoot Y. When the table is moved forward, the lowest nut engages the tap, and the lever I is operated to lock the wheel M in a fixed cone in the standard B', the tap being rotated at a slow rate. On completion of the tapping the table is drawn back by the operator, the wheel M being simultaneously moved forward to engage the wheel N so that the spindle is rotated at a quicker rate in the opposite direction. The nut travels in a slot, which prevents it from rotating, till it arrives over an aperture Z, through which it falls when the tap is withdrawn. Fig. 3 shows a pair of grippers b, operated by a screw c, to grip the articles when they are circular. If discs are being operated on, the lowest one falls through a slit in a fixed bar a passing freely through the table W.

Granted: 1899-08-05
Abstract: 11,420. Abel, C. D., [Benno JaffÚ & Darmstaedter Lanolinfabrik]. June 1. Medicinal preparations.-Quinates of piperazine and of its derivatives, such as dimethyl-piperazine and alkaline salts of such quinates, which are suitable for preventing the formation of uric acid and in cases of gout, stone, neurasthenia, and the like, are produced by the following processes, viz :-(1) A molecular proportion of piperazine, or a derivative thereof, and two molecular proportions of quinic acid are mixed together in the solid state and then heated at the melting temperature for some time. The mass produced may be used as it is, or it may be dissolved in water and be reprecipitated therefrom by absolute alcohol. (2) Equivalent quantities of piperazine and quinic acid are dissolved in the minimum quantity of water, the solution is concentrated on a water bath, the remaining water is removed by repeated evaporation with a small quantity of alcohol, and the residue is dried in vacuo. Alternatively, the new salts are precipitated from their concentrated solution by addition of absolute alcohol. Quinates of piperazine and its derivatives are white crystalline powders of feebly-acid taste and soluble in water. (3) These compounds yield alkaline salts, for example those of sodium, potassium, and lithium, when their aqueous solutions are mixed with molecular proportions of the alkaline carbonates and the mixtures are evaporated to dryness.

Sewage and foul waters, treating ; bacteriological processes; filtering.-Relates to the automatic supply of sewage or other liquid to, and the withdrawal from, filter beds arranged in a series and in accordance with a pre-arranged order. Reference is made to Specification No. 2647, A.D. 1900. Fig. 1 shows, in plan, several beds of a number arranged in a series, and all fed from a common main G. Each bed, such as 3 or 4, is supplied from a separate inlet valve, such as A<3> or A<4>. The valves are mounted on levers such as E<3>, E<4> pivoted at D<3>, D<4> and actuated by floats F<3>, F<4> arranged in chambers f<3>, f<4>. The chambers f<3>, f<4> are connected by means of pipes b<3>, b<4> with the filter bed immediately preceding it in the series. By this arrangement, when one bed such as 3 is being filled, the chamber f' is simultaneously filled and the float F' is so arranged that the inlet valve A' to the bed 4 is opened as soon as bed 3 has been filled. In the same way, the bed 2 is emptying as the bed 4 is filling, and as it empties, the chamber f<3> is also emptied, thus allowing the float F<3> to fall and close the inlet valve A<3> to the bed 3. Each bed is provided with an outlet valve, such as O<3>, O<4>, also actuated by floats, such as J<3>, J<4>, in chambers, such as j<3>, j<4>. The chambers j<3>, j<4> are connected by pipes such as B<3>, B' with the beds immediately succeeding them in the series, so that, as one bed fills, the outlet valve of the preceding bed is opened. Another arrangement is described in which the beds discharge their contents into second beds at a lower level before passing into the main outlet. The Specification describes various forms of valves for use in the apparatus, and also means for cutting one of the beds out of the series, if desired.
