STEAM DISINFECTION. A T the value of high-pressure, dry, saturated T Hsteam as an effective means of destroying pathogenic or disease-producing organisms is becoming increasingly recognised is amply demonstrated by the number of government and municipal authorities which have adopted the "Alliott & Paton" type of steam disinfector. In disinfecting by steam it is a matter of primary importance that air should be expelled from the steam disinfection chamber during the process, and this has been attended hitherto with considerable difficulty. Messrs. Manlove, Alliott & Co., Ltd., claim for their type of disinfector the thorough exhausting of the steam by producing such a vacuum in the chamber that it not only ensures the removal of the last traces of moisture, but also direct and complete penetration by the warm air at the conclusion of the operation. A typical corporation disinfecting station, and in many respects a model one, is that which has been erected by the Royal Borough of Kensington at Wood Lane. The building is a substantial erection of glazed brick and terra cotta. Glazed bricks have also been employed in the interior to a height of 4 ft.,the remainder
of the walls being lined with glass tiles. This method of construction has been adopted in order to enable the building to be washed down at intervals both inside and out..The accommodation provided includes an "infected room" and a "disinfected room." There is also a laundry, comprising a washing room, and an ironing and packing room. The disinfection of vehicles has also been provided for in an air-tight chamber of suitable size, into which an infected cab or carriage may be placed when required. The disinfector house is divided into two distinct sections, the "infected" department having no direct communication with the "dlsinfected" side. Separate mess-room accommodation, lavatories, and bath-rooms are provided in connection with each section. The only direct communication with the two departments must be made through the two "Alliott & Paton" dlsinfectors, which are fitted in the dividing wall, the doors on one side always being kept dosed when those on the opposite side are opened. The disinfectors are of the oval type, and an illustration will be found on page iii, together with other specialities manufactured by Messrs. Manlove, Alliott & Co., Ltd.
