Title: Manufacture of materials suitable for addition to toilet baths
IPC: A61Q19/10
Filed: 1928-02-13
Abstract: 285,356. Drangsholt, C. Feb. 12, 1927, [Convention date]. Medicinal bath preparations.-Alkali humates, for instance the sodium or lithium salts or mixtures thereof, are used for preparing medicinal baths. Humic acid is obtained from peat by crushing, disintegrating with water and heating to 100‹ C., or by freezing followed by heating. The mass is then extracted with alkali carbonate or hydroxide or with sodium sulphide or acid sulphide. Acid is added to the humate solution so obtained to precipitate humic acid which is extracted with a solvent such as alcohol to obtain a substance consisting mainly of hymatomelanic acid from which alkali salts are prepared. Soluble humates, obtained by the freezing process referred to, may be treated directly with acid to obtain the humic acid. The Specification as open to inspection under Sect. 91 (3) (a) states that the humic acid may be dissolved in alkali hydroxide and used without extraction with alcohol. This subject-matter does not appear in the Specification as accepted.

[Class 75 (i).] A flashlight lamp comprising a bulb containing a flashlight charge of powder, gas, vapour, or metal strip, foil, wool, or dust or mixtures thereof is provided with a disruptible seal adapted to be pierced by the stem of an igniting device. Fig. 1 shows a translucent bulb 1 having its cap 2 formed with an opening 5 closed by a seal 6 of sheet rubber, metal foil, paraffin wax, sheet collodion &c. adapted to be pierced by an igniter stem 8 in which a match-stick 9 carrying an ignition pellet is supported by insulated spring fingers 12, 13. A battery holder 18 is fitted with a bayonet socket 17 adapted to receive pins 16 on the bulb and carries a reflector 19. On pressing a trigger 25 current will flow from the battery through the spring fingers 12, 13 along metal strips at the sides of the matchstick 9 to ignite the ignition pellet and flash the charge. The electric circuit may be tested by depressing a pilot bulb 26. A remote operating switch 29 may be plugged into the holder 18. Alternative igniting devices such as sparking points or an incandescent resistance wire internal to the bulb, or sympathetic or other igniting means external to the bulb may be employed. Rupture of the bulb by the pressure on ignition is prevented by providing apertures 3 covered by a tensioned rubber band 4 in the cap 2. Fig. 2 shows an igniting device in which a percussion cap 137 is inserted in a hollow stem 135 between a piercing head 131 and a displaceable head 136. The stem 135 is carried by a holder 122 fitted with a tubular mounting 123 for a reflector 124. A sleeve 127 having pins 125 engaging bayonet slots in the mounting 123 is slidable on the stem 135 and carries a spring pressed valve 132. The flashlight bulb 130 may be secured by bayonet pins 129 to the sleeve 127 when the sleeve is in its right hand position (shown dotted), the ruptured seal being closed by the valve 132. The sleeve is then drawn back by pressure on the pins 125 to the position shown in full lines. To ignite the charge a hammer 138 is released to fire the percussion cap by means of a trigger 141, excess pressure being relieved by the valve 132. The release pressure may be adjusted by varying the tension of the spring 133 by means of screws 134. The bulb may be provided additionally with perforations covered by rubber bands and may have a protecting covering of gauze or perforated metal to prevent the occurrence of external ignition.
