Title: Improvements in or relating to the preparation of polymers from diphenyl
Inventor: DENSHAM ALEC BRAMLEY
IPC: C08G61/02
Filed: 1948-09-29
Abstract: Polymers of dihydrodiphenyl are prepared by reacting diphenyl with metallic sodium in an inert atmosphere, decomposing the 1,4-disodium diphenyl formed to dihydrodiphenyl and polymerizing the latter in ethylene glycol dimethyl ether in the presence of disodium diphenyl. The disodium diphenyl may be formed by adding sodium to a solution of diphenyl in ethylene glycol dimethyl ether in an atmosphere of nitrogen and is then hydrolysed by water.  If decomposition is complete, further disodium diphenyl is added as polymerization catalyst.  The caustic soda precipitated by hydrolysis may be filtered off and washed with the ether and the filtrate and washings treated again with sodium followed by hydrolysis and filtration. This may be repeated and the polymer, formed as the moenmer is produced by hydrolysis, is recoverdo by distilling off the ether at atmospheric pressure and then distilling at an elevated temperature under reduced pressure.  The sodium hydroxide may alternatively be left in the mixture and after distilling off the ether the polymer is extracted, e.g. with diethyl ether.  In a modification, sodium may be added to a dimethyl ether solution of diphenyl at a temperature below - 28 DEG  C. and the disodium diphenyl decomposed with methanol. Di-isopropyl ether is added, the dimethyl ether removed by distillation and the sodium methoxide washed out with water.  The di-isopropyl ether is distilled off and the dihydrodiphenyl polymerized by the addition of a solution of disodium diphenyl in ethylene glycol dimethyl ether, e.g. at 25-30 DEG C.ALSO:Dihydrodiphenyl is formed by reacting diphenyl with metallic sodium in an inert atmosphere and hydrolysing the 1.4-disodium diphenyl formed.  The reaction with sodium may take place in dimethyl ether or ethylene glycol dimethyl ether and hydrolysis effected with water or methanol.  To isolate the product, reaction with sodium is effected in dimethyl ether at a temperature below -28 DEG  C. and the disodium diphenyl hydrolysed with methanol. Di-isopropyl ether is added, the dimethyl ether removed by distillation and the sodium methoxide previously formed washed out with water.  The di-isopropyl ether is then removed by distillation.

Title: Automatic machine to register the score of the game called lawn tennis
IPC: A63B71/06
Filed: 1922-09-21
Abstract: 209,791. Brown, D. H. Sept. 21, 1922. Scoring-apparatus. - Relates to apparatus for recording sequences of events, particularly the scores in lawntennis. The apparatus, which is adapted to be contained in a watchcasing for attachment to the wrist, comprises two sets of scoring devices operated by plungers or levers against the action of springs, each set having a series of scoring dials for each player. In scoring lawn-tennis, points are added by pressing the appropriate plunger k which causes the pawl 15 which it carries to rotate a ratchetwheel 10 carried by a spring drum z, which drum is then rotated one twenty-fourth of a revolution. Teeth y on the drum z engage a pinion on one spindle 2, to rotate a dial carried by the spindle one-sixth of a revolution, a numeral carried by the dial being displayed at a " point " aperture in the casing. On four points being scored, teeth on a wheel 26 on the spindle 2 engage a toothed wheel 27 on a spindle 3, turning it one-sixth of a revolution, to display a numeral in a " game " aperture. In a similar manner, " sets " are displayed by the engagement of the teeth on a wheel 28 on the spfindle 3 with a wheel 29 on a spindle 4. On the winning of a game by one player, the points scored by the other player are cancelled by the operation of a lever l which carries a member 24 which engages a spring- pressed pawl 11. As the pawl 11 is moved into engagement with a ratchet-wheel 9 carried by the drum z, a projection 23 on a second pawl 20 is pressed, bringing the pawl 20 out of engagement with the wheel 9. The drum z is thus allowed to move backwards a definite amount by the spring x unwinding and the player's points are cancelled. In a similar manner " game " and " set " scores are cancelled by the operation of levers m, n, which release ratchet-wheels 8, 7 on the drum z. If it is necessary to score " advantage " points, a lever p is moved to operate by means of a toothed segment a dial which displays the point in an appropriate aperture. A similar arrangement may be employed for " advantage " games, or, alternatively, means for the cancellation of a game are provided.
