Patent GB-669070-A (GB)
Title: Improvements in or relating to compounds of the dimethyl xanthine series and production thereof
IPC: B64C3/00
Filed: 1949-06-14
Abstract: Theophylline is reacted in alkaline medium with a dialkylamino-alkyl halide, the latter alkyl group containing 2-4 carbon atoms; alternatively, theophylline is treated with a glycol monochlorhydrin to form the hydroxyalkyl derivative, converted into the chloroalkyl compound and finally reacted with a dialkylamine.  The products are the 7-dialkylaminoalkyl derivatives and may be converted into quaternary salts and acid addition salts.  In the examples: (1) theophylline is converted directly into 7-(b -diethylaminoethyl)-theophylline; (2) the product of (1) forms a hydrochloride, hydriodide, camphosulphonate and picrate by direct addition or double decomposition; (3) the product of (1) is reacted with methyl iodide; (4) as in (1)-(3) using b -dimethylaminoethyl chloride; (5) theophylline is reacted with bromocholine bromide to give a quaternary salt directly; (6) theophylline is converted successively into the 7-b -hydroxyethyl, 7-b -chloroethyl and 7-b -diethylaminoethyl derivatives.  The Specification as open to inspection under Sect. 91 mentions similar reactions with theobromine, where substitution occurs in the 1-position.  The substituent in the product from theobromine or theophylline may be any organic radical containing a primary, secondary, tertiary or quaternary amino group.  A further product specified is 1-(2-diethylaminoethyl)-theobromine.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in means for locating the source of sounds
IPC: G01S1/72
Filed: 1919-06-23
Abstract: 148,678. Anderson, A. June 23, 1919. Locating sounds.-Relates to s o u n d - locating apparatus, specially adapted for ascertaining the point of a subaqueous explosion or the location of a gun firing in air, of the type employing a number of soundreceivers stationed at predetermined positions and a recording-instrument giving a record of time intervals which elapse between the reception of the sound at the respective receivers. The invention consists in the use of transparent templets for ascertaining the position of the source of sound on a chart. The position of the sound-receivers H1, H2, H3, H4 is marked on the chart, Fig. 5, and circles or arcs are described about these points, the respective radii being the distances the sound waves have travelled in the respective time intervals which elapse between the reception of the sound at the position of the first receiver H1 actuated, and its reception at the other receivers. A transparent templet is then placed over the chart and a circle or arc W1 on it found by trial, which passes through the position of the first receiver actuated and is tangential to all the other arcs or circles on the chart. The templet, Fig. 2, consists of a glass or celluloid plate upon which are etched arcs, the centres of which all lie on the central radial line AB when produced, the respective radii being indicated at the extremities of the arcs on the edges of the plate. Two bevels are provided at the upper and lower ends of the common radial line for accurately marking its direction on the chart. From the direction of the radial line and the position of the arc, the bearing and range of the source of sound can easily be ascertained. When the explosion takes place in the vicinity of the sound-receivers, complete registering circles are required and a templet as shown in Fig. 3 is used. The centre of this templet will give the required position, and to enable this to be marked on the chart a hole is provided at the centre. To facilitate the selection of the templet on which a required arc will be found, an index templet marked with the limiting arcs only of a series of templets is first placed on the chart.

Title: Improvements in rotary agitators
IPC: B03D1/16

Abstract: 902,461. Mixing and agitating appliances; froth flotations. WESTERN MACHINERY CO. May 8, 1959 [May 12, 1958], No. 15840/59. Classes 82 (2) and 86. A froth flotation cell for mineral separation by the method wherein the addition of a reagent to a water slurry of the crushed ore enables the wanted mineral to be entrained in a froth, has a squirrel-cage type agitating rotor on a vertical shaft 60 and positioned for rotation in a similar stator 20 which is supported above the bottom of a tank 14. The rotor comprises vertical rubber-covered metal rods 72, Fig. 4, connecting the peripheries of ring members 66, 68 having spokes shaped to form impeller vanes (see Fig. 3). The slurry is supplied to the feed-box 12 and passes under a partition into the tank 14 ; the rotor impeller rings 66, 68 draw air from the trunk 34 and slurry from the bottom of the tank 14 into the space within the rotor, which expels them by centrifugal force and impeller action between the bars of the rotor and the stator. The turbulence thus created forms a froth 18 which entrains particles of the mineral which it is desired to separate and which passes over a weir (not shown) to be collected ; the remaining slurry passes into the discharge box 16 over a weir 78 or through an adjustable gate 80. The rubber covering of the vertical bars of the squirrel cage is rhombic in cross-section as at 92, Fig. 4; in the prior act the crosssection is circular as at 88. The longer diagonal of the rhombus is aligned with the direction of the relative velocity of the slurry in relation to the bar; the bars may be turned through 180 degrees after they have reached the limit of wear.

When a free radical catalyst, e.g. azodi-isobutyronitrile, or ultraviolet light is used, the products contain units of the formula and Examples 8-11 illustrate the modification of 1,4-cis-polybutadiene, nitrile rubber and styrene / butadiene / styrene block copolymer. The latter modified product was then partly hydrolysed. When the reaction is conducted in the absence of a catalyst the products contain units of the formula in which X is a sulphochloride group (SO 2 Cl). Examples 1-5 and 7 illustrate the modification of natural rubber, synthetic - 1,4 - cis - polyisoprene, butyl rubber, 1,4 - trans - polychloroprene and degraded natural rubber. Products of type I may be hydrolysed to give products containing units of formula I in which X is hydrogen, the hydrolysis being effected by dissolving the polymer in a ketone and pouring the resulting solution into water containing a base at 80-85 C. Examples 6 and 7 illustrate the hydrolysis of products of formula I derived from natural rubber and degraded natural rubber. The above treatments may also be applied to vulcanized rubbers. Example 17 illustrates the treatment of vulcanized polyisoprene plates with chlorosulphonyl isocyanate in the absence of a catalyst, followed by hydrolysis. Surface modification is effected. The above products containing units of formula I and II may be subjected to further reactions. In Example 12, modified natural rubber of type I is hydrolysed to effect opening of the lactam ring, the product having units of the formula which in Example 13 is heated with hydrochloric acid to give a product containing units of formula In Example 14, modified natural rubber of type I is reacted with aniline to effect substitution of the chlorine atoms of the SO 2 Cl groups, resulting in a product containing units of formula Example 16 describes the conventional vulcanization of modified natural rubbers.
