Patent GB-1331006-A (GB)
Title: Escapement mechanism
Inventor: STUBBMANN A
IPC: G04B15/00
Filed: 1972-02-08
Abstract: 1331006 Escapements KOHNER BROS Inc 8 Feb 1972 [9 March 1971] 5903/72 Heading F2X [Also in Divisions A6 and G5] A motorized toy has a hub 14 secured to a shaft 70 with a plurality of arms (Fig. 1, not shown) radially extending from the plug. A motor, e.g. a spring motor 36, 38, is provided for rotating the shaft 70. An escapement mechanism controls the rotation of the shaft 70 and includes a tube 106 that is rotatable in conjunction with the shaft 70. The tube 106 is closed at its ends and has a pair of magnets (108, 110) (Fig. 4, not shown) therein. The magnets have their south poles facing each other with the north poles diametrically opposed to each other. The magnets can move within the tube 106. A lever 122 is positioned adjacent the tube bottom when the tube 106 is vertical, is rotatable about a pivot 120 to a vertical position and includes a stop 124. The stop 124 prevents rotation of the tube 106 when the lever 122 is in the vertical position. A magnetic means biases the lever 122 to the vertical position. If the tube 106 is in a vertical position with the magnets therein at the top of the tube, the lever 122 will be in a vertical position as a result of the magnetic biasing means and the stop 124 will prevent rotation of the tube 106. The magnets in the tube will descend to the bottom of the tube under the influence of gravity and the bottom-most magnet overcomes the magnetic biasing means and any frictional forces and causes the lever 122 to be moved out of its vertical position. Consequently, the tube 106 and the shaft 70 are free to rotate. After the tube 106 is rotated a few degrees, the magnetic biasing means then moves the lever to a vertical position and the cycle is again repeated after the tube has come to a vertical position.

Abstract: Compounds are made by reacting adenylic acid or sodium adenylate with one or more components of the Vitamin B complex (including choline), or their acid salts.  If free adenylic acid is reacted with an acid salt sodium hydroxide is added subsequently.  The reaction takes place in aqueous solution or suspension, preferably with heat, and the product may be obtained solid by evaporation or addition of an organic solvent in which it is insoluble.  The inorganic sodium salt may if desired be separated.  The reactants are preferably used in stoichiometric proportions.  Examples show the preparation of the following: (1) di-nicotinamide adenylate; (2) thiamine adenylate; (3) pyridoxin adenylate; (3) mono and diadenylates of riboflavin; (4) choline adenylate.  The process is applicable to both yeast and muscle adenylic acids.  The Specification as open to inspection under Sect. 91 refers to the use of other adenylates, viz. those of potassium, lithium, magnesium, zinc, manganese, iron, copper, cobalt and calcium.  It also includes the subject-matter of Specification 698,864, and also describes products similar to those of that Specification but obtained from members of the Vitamin B series and amino-acids without adenylic acid.  This subject-matter does not appear in the Specification as accepted.ALSO:Medicinal preparations comprise adenylic acid or sodium adenylate with one or more components of the vitamin B complex (including choline) or their acid salts.

Title: Improvements in or relating to the concentration and purification of latex
IPC: C08C1/08
Filed: 1930-02-25
Abstract: The creaming of latex by the addition of gums, hydrophilic colloids, karaya gum, gelatin, pectin, ammonium alginate, &c., is expedited by the imposition of an electrical strain before, during, or after the addition of the creaming agent, without causing any material current flow through the latex, or deposition of rubber at the electrodes. Direct or alternating current may be employed.  The electrodes may be coated with an insulating layer to minimize passage of current. Details are given of suitable voltages, area, and distance apart of electrodes, times of treatment, &c.  In an example, normal latex containing 0,2 parts of ammonium alginate to 100 parts of solids is fed between uncoated electrodes of 30 sq. in. area, 4 inches apart at a rate of 25 gals. per hour with an applied A.C. voltage of 110.  The latex creams (55 per cent solids) in 1-2 hours instead of 24-36 hours for untreated latex.  With a voltage of 220, 100 gals. of latex should be passed per hour.  By an increase of creaming agent, a serum containing less solids is obtained.
