Title: Improvements in or relating to the treatment of cellulose nitrate
IPC: C08B5/02
Filed: 1934-12-17
Abstract: Cellulose nitrate is suspended, after the usual stabilization or purification, in an aqueous liquid having a pH value lying between about 3,5 and 6,5, preferably between 3,5 and 4,0, whereby the fines become separated from the relatively long fibres, the long fibred cellulose nitrate is allowed to settle, and the aqueous liquid containing fines in suspension is decanted. Water may then be added, the long fibred cellulose nitrate is again allowed to settle, and the water containing the fines is decanted.  These steps are repeated until the decanted water is substantially free from milkiness.  The supernatant liquid is conveniently drawn off by means of a pipe, or a rotating bailer washer is used, fresh water being continuously introduced preferably near the bottom of the washing tub.  In an example, cellulose nitrate of 11 per cent nitrogen content is boiled in acid of about 0,5 per cent strength.  The acid is drained and the nitrate given two washes with bottom drainage.  It is then agitated with water, which will have a pH value of about 3,5 to 4,0 due to diffusion of acid from the nitrate, allowed to stand for 2 or 3 minutes, and the milky liquor decanted off.  The washing and decanting are repeated until the decanted liquors are clear.  In a second example, a hexagonal rotating bailer washer is used, and the flow of wash liquor is continuous.

Title: Process for producing resinous products
IPC: C08G12/12
Filed: 1929-11-26
Abstract: For the production of resins of the urea-formaldehyde type in the form of moulding powders, the hydrion concentration of a solution of formaldehyde is reduced by adding an organic base, and urea is added to produce a solution containing not less than 2 mols. of formaldehyde to 1 mol. of urea; the solution is heated, treated with additional urea, reheated, and concentrated; it is then rendered neutral or feebly alkaline, treated with thiourea or with additional urea, and further evaporated; the product is then dried and ground. In an example, an aqueous solution of formaldehyde (about 3 mols.) is treated with ethanolamine or other base to establish a hydrion concentration pH 6,6, and urea (1 mol.) is added.  The solution is boiled under reflux until spontaneous boiling ceases, and additional urea (about 0,3 mol.) is added.  The solution is refluxed again and then evaporated to a syrup in an open pan.  The pH is then adjusted to 7,3, and about 1 mol. of thiourea is added for each 2 mols. of uncombined formaldehyde, which should be determined by analysis.  The syrup is boiled and further evaporated, while passing air through it, and when a very thick syrup is obtained the pH is again adjusted to between 5 and 3, and a plasticizer is added.  Suitable plasticizers which serve also to adjust the hydrion concentration are acid esters of polybasic acids with polyhydric alcohols, e.g. a compound of the glyptal type or a compound formed by reacting phthalic anhydride or malic or camphoric acid with glycol or with a carbohydrate such as glucose, saccharose, starch or cellulose. Other plasticizers such as N-alkyltoluenesulphonamides or naphthols may be used, the pH then being adjusted by means of an organic acid such as phthalic, tartaric or salicylic acid. The plasticized and acidified syrup is dried in a vacuum drier and then ground; the product may be further dried after grinding. Dyes, pigments or fillers may be added with the plasticizer.

Title: Improvements in method and apparatus for the measurement of distances by means of electromagnetic waves
IPC: G01S13/82
Filed: 1928-12-17
Abstract: 302,602. Koulikoff, A., and Chilowsky, C. Dec. 15, 1927, [Convention date]. Distances, determining.- Relates to systems of the kind described in Specification 288,233 in which the transmission of a wavetrain from a local station serves to energize a distant station which thereupon retransmits a second wavetrain, the timeinterval between the emission of the first and the receipt of the return wavetrain serving to indicate the distance separating the two stations. According to the present invention transmission is periodically interrupted to allow reception to take place. Fig. 1 illustrates the arrangements at the local station. An oscillator valve 11 is coupled through coils 13, 7 to interrupt or modulate the radiation from a high-frequency generator 1 feeding the aerial 5. At the same time it is coupled through coils 14, 15 to a receiver valve 16 in such a way as to render the latter sensitive only during the intervals in which the generator 1 is quiescent. Fig. 2 shows the distant station. Incoming signals received on the aerial 23 are applied through coils 30, 40 to the grid of a modulating-valve 41, and serve to interrupt or modulate the outgoing or return wavetrain from the generator 1 destined to be received on the aerial 20, Fig. 1, of the original or local transmitter. The distance in question can be determined by varying the local modulation frequency until a maximum reception is obtained in the telephones 68, 69 of the local station. The modulation frequency then corresponds to the time taken by the wavetrain to travel to and return from the distant station. Or a minimum reception effect can be utilized, suitable correction being made in both cases for the time-constants of the respective circuits. Or the distance may be measured by the apparatus described in Specifications 227,801, 230,013; and 241,505, [Class 118 (ii), Signals], in combination with a ballistic galvanometer for integrating the total current received in a definite interval of time. The outgoing and return wave-trains may be of the same or different frequency. In a modified form the same aerial is used both for transmission and reception at the local station, whilst separate aerials are used at the distant station for reception and re-transmission. The method is applicable to determine the distance between ships at sea, between a ship and the coast, between an aeroplane and the ground, orbetween running trains or a train and a station. A lighthouse or beacon, for example, may be fitted with several active or local transmitters, the corresponding distant or passive station being carried by a ship or aeroplane, to which the respective distances may be transmitted by special signal from the operator at the lighthouse- or beacon.
