Title: Device for keeping the movement of clocks synchronous
IPC: G04C11/00
Filed: 1925-08-28
Abstract: 250,164. Landis et Gyr Soc. Anon. April 1, 1925, [Convention date]. Synchronizing.-Contacts at the master clock close a circuit to a magnet in each secondary clock which magnet coacts with a cam-operated lever to stop the secondary clock and to restart it at the synchronizing moment. A few minutes before synchronizing a cam 7 rotates a lever 3 clockwise to close the said. contacts 1<1>, 2 at the master clock. This energizes a magnet 22 which attracts its armature 23 counterweighted at 25. When the secondary clock shows the time for synchronizing a cam 28 in it releases a lever 24 which rotates anticlockwise against a stop 27 and places the finger 34 in the path of the balance wheel 35. At the correct moment the cam 7 releases the lever 3, contacts 1<1>, 2 are broken, magnet 22 is de-energized and the armature 23 kicks against the lever 24, lowering the finger 34 and restarting the secondary clock. The cams 7, 28 are adjustable angularly on their shafts by couplings 17, 32 respectively and a pendulum may be substituted for the balance wheel.

Title: Improvements in the purification of triaryl phosphates
IPC: C07F9/12
Filed: 1959-06-24
Abstract: A crude triaryl phosphate is purified by washing the phosphate with dilute aqueous caustic alkali solution and, simultaneously or subsequently, with a dilute aqueous hypochlorite solution.  The phosphate is then desirably washed with water before drying it and the waste water from this washing can be employed in making up the alkali and hypochlorite solution or solutions.  The washing operations are preferably carried out at elevated temperature, e.g. at from 50 DEG  to 99 DEG C.  After dying the phosphate may be subjected to the conventional clay treatment, e.g. with fuller's earth.  It is preferred to use caustic soda and sodium hypochlorite. The alkali is preferably used in the form of a 0.1 to 5% aqueous solution and in an amount equivalent to about 10 to 100 times the acidity of the phosphate.  The hypochlorite solution is preferably used in the form of a 0.1 to 5% aqueous solution and when sodium hypochlorite is used it is suitably used in quantities of from 0.6 to 6.0 parts by weight per 100 parts by weight of the phosphate.  The phosphates treated are preferably tri(methyl substituted phenyl)phosphates e.g. those derived from cresol or xylenol or cresylic acid.  Phosphates derived from phenol itself, other alkyl substituted phenols, mixtures of phenols, or from halogen- or nitro-substituted phenols may also be used.  The process can be carried out continuously.  Examples are given and reference is also made for comparative purposes to treating the crude phosphates with a solution of caustic soda containing hydrogen peroxide for purification purposes.  The phosphates submitted to the purification process may be obtained by reacting an excess of the hydroxyaryl compound with phosphorus oxychloride in the presence of magnesium chloride, aluminium chloride or zinc chloride as catalyst.
