Title: Improvements relating to contact arrangements for thermostatic electrical switches
IPC: H01H37/56
Filed: 1935-01-24
Abstract: 441,237. Thermal switches. ANNAN, R., Saxonbury, St. Mary's Road, Surbiton, Surrey, and McKINLAY, A. B., 8, Woodlands Road, Barnes, London. Jan. 24, 1935, No. 2361. [Class 38 (v)] In a thermal switch, suitable for mounting on the ceiling of a ship's cabin to give warning of fire, and comprising two thermal elements such as bimetallic spirals g, h arranged to control contacts r, t by relative movement due to unequal heating, the free ends of the thermal elements are connected by a link u which does not interfere with the above relative movement but ensures that other movements due to vibration are transmitted from one element to the other so that the two elements vibrate as a single unit. The contacts r, t are carried by the spirals h, g respectively, the contact t being mounted on a strip s fixed to the spiral g. The masses of the two contacts may be adjusted so that the natural frequencies of the two spirals differ. In the form shown, the spirals are separated from each other by a metal plate d, and in the event of a fire hot air enters the casing m through holes n and leaves by holes o. The lower spiral h is therefore heated more than the upper spiral g and the contacts r, t engage. Slow heating of the cabin causes no relative movement of the contacts unless temperature rise is enough to bring the contact t against a fixed stop, after which contact does take place.

Title: Process for the manufacture of cellulose esters
IPC: C08B3/24
Filed: 1936-01-29
Abstract: Fully esterified cellulose esters made by treating cellulose material with a fatty acid or anhydride and an acid catalyst while retaining the fibrous state, are subjected to partial deesterification by dissolving them in a concentrated lower fatty acid containing a salt of a weak acid and heating, the reaction being terminated when the products have become soluble in acetone.  The salt reacts with and neutralizes the residual catalyst.  Sodium formate, acetate, borax, soap, and phenolates are specified salts.  In addition to alkali or alkaline earth salts, salts of heavy metals may be used if sufficiently soluble. The hydrolysing acid may be formic, acetic, or propionic.  It may be used in anhydrous state or it may contain some water.  Mixtures of acids with each other, or with phenols or other solvents may be used.  The temperature employed for the treatment may be 80--120 DEG  C.  The reaction may be stopped by lowering the temperature or pouring the solution into water or ether.  The product may be precipitated in the form of foils or powder.  It may be further stabilized by heating with alcohols such as glycol or glycerine. In an example, fibrous cellulose triacetate is freed by means of benzene from the esterifying bath containing sulphuric acid as catalyst, and is then dissolved in concentrated acetic acid containing sodium acetate and heated until the product is soluble in acetone.  In another example, fibrous cellulose propionate is dissolved in strong propionic acid containing sodium propionate. Tetrachlorethane is added and the mixture is heated until the desired acetone-solubility is attained.  Specifications 381,991 and 402,692 are referred to.

Abstract: 104,890. Jackson, W. J. Mellersh-, (Koppers Co., H.). Feb. 28, 1916. Hydrocarbons, distilling; column stills; progressive evaporators. - In distilling hydrocarbons such as benzol and its homologues from oils in which they have been absorbed, for example from coal-gas or natural gas, the oils are preheated by means of the vapours and the hot residual oil from the still, before passing through the superheater to the still. The cold oil entering by a pipe 10 passes through a preheater A, to which vapours from the still D are led by a pipe 19, and then flows through a pipe 11 to a preheater B receiving hot residual oil from the still by a pipe 12. The heated oil flows through a pipe 13 to a superheater C heated by live steam, whence it is led by a pipe 17 to the still. Free steam is admitted at the base of the still by a pipe 18. The vapours, after passing through the preheater A, are led to a condenser E and a water-separator F. The hot residual oil flows from the preheater B through a series of coolers G, G<1>, G<2>. A duplicate superheater C<1> is provided, and the cooler G is so arranged that it may be used as a preheater, valved connexions being provided in each case so that either the superheaters C, C<1> or the preheaters B, G may be used singly, or in parallel, or in series. The heat-exchangers A, B, C, &c. comprise horizontal tubes between headers, together with suitable baffles and partitions to impart a zigzag path to the fluids. In the case of the superheaters C, Fig. 10, the upper part of the casing is free from tubes, and the baffles are stopped short of the top of the casing, a vapour space being thus formed in the superheaters, whence the vapours generated from the wash-oil are led by a pipe 15 to the still D. The still D is formed of sections of the construction shown in Fig. 1.
