Title: Improvements relating to the coating internally of hollow articles with metal
IPC: C23C26/02
Filed: 1924-04-22
Abstract: 238,921. Daimler Co., Ltd., Needle, G., and Lanchester, F. W. April 22, 1924. Metal pipes and tubes.-In a method of coating hollow articles, particularly the sleeves of sleeve valve engines, internally with metal, the article a is mounted between an upstanding portion c of a mandrel b and an abutment d slidably mounted on the mandrel b and held in position by nuts e, f and a spring g. Non-oxidizing gas e.g. coal gas, is introduced by a pipe k into the interior j of the mandrel and passes by apertures h into the space o between the mandrel and the article a, the gas leaving the space o by apertures n in the part c and passing away by a pipfl m. The article is rotated either at a slow uniform speed or eratically by a pulley v driven from a pulley v mounted on a shaft w connected by a Hooke's joint t to an electric motor p mounted on a swivelling bed plate s adapted to be moved by a lever r, the movement, of the plate s being limited by stops q, z. In operation a suitable flux is applied to the interior surface of the article and lumps of the coating metal are placed in the space o. The non-oxidizing gas is admitted by the apertures h into the space o until all the air has been expelled therefrom. The article is then heated externally, gas still being passed into the space o and the mandrel b is then rotated at a slow uniform speed or erratically, by moving the plate s into the inclined position, so that a direct surface alloying of the coating metal with the metal of the article a is produced. The mandrel b is then rotated uniformly and at a comparatively high speed so as to distribute uniformly the melted coating material. The temperature of the article is then reduced below the melting point of the coating metal and the mandrel rotated until the coating s has set. The erratic and subsequent faster motion may be produced by a pair of elliptic gear wheels and a pair of ordinary spur-wheels, the driving member of each pair being keyed permanently to the driving shaft and either of the driven members clutched at will to the driven shaft. The slow and subsequent faster motion may be produced by two pairs of spur gear trains. Lined split bearings may also be produced, the two halves of the bearings being separated by plates to prevent the coating metal joining the two halves together.
Patent GB-191104979-A (GB)
IPC: A62C3/10
Abstract: 4979. Sluyterman, A. C. Feb. 28. Fire-extinguishing by gases.-Relates to fireextinguishing and fumigating apparatus of the type in which gas is produced from liquid sulphur dioxide &c. carried under pressure in cylinders, and more particularly to an arrangement whereby the liquid sulphur dioxide is heated in the gasifier either by means of hot air taken from the compartment which is on fire, or by means of exhaust steam, exhaust gases, live steam, &c. obtained from an engine &c. The cylinders of liquid sulphur dioxide are connected by pipes A', A<2> to heating-coils in the gasifier A, from which the gas passes by pipes B<1>, B<2> to a mixing-chamber B connected at one end to a blower B<3>, which is driven from a steam-engine B<5> and delivers into piping leading to the hold or other compartment to be treated. The gas and air leave the compartment. through a return pipe, which is branched, so that the mixture may be passed either through an opening C controlled by a two-way cock C<2> into the gasifier A to heat the liquefied gas, and thence through a passage C<5> and a four-way cock C' into the mixing-chamber B for further circulation, or the gaseous mixture may be passed direct into the mixing-chamber B through an opening C<3> and the cock C<4>. In the latter case, the gasifier A is heated either by exhaust from the engine B<5> admitted through a pipe E and a three-way cock E', or by live steam admitted through a pipe E<2>, the steam escaping to the atmosphere through an outlet C<6> controlled by the four-way cock C<4>. The cocks C<2>, C<4> are connected by levers and connecting- rods D to a hand-lever D<3>, so that they can be set simultaneously either for the air-heating or steam-heating of the gasifier. In some cases, the gaseous mixture from the compartment is not re-aspirated, but is allowed to escape to the atmosphere through a two-way cock fitted to the return branch-pipe connected to the opening C<3>.
