Title: Calcium silicate pesticidal carrier
IPC: A01N25/08
Filed: 1958-08-14
Abstract: Diatomaceous calcium silicate, produced by reacting hydrated lime and diatomaceous earth as described in Specification 268,011, is reacted at 0 DEG -90 DEG C. in the presence of water with carbon dioxide until a carbonated diatomaceous calcium silicate is obtained which has a bulk density of 8,45 to 0,54 grams per cubic centimeter and which imparts a lower pH to an aqueous system than the diatomaceous calcium silicate before carbonation. The carbonated product is particularly suitable as a pesticide carrier.  The carbon dioxide may be employed in gaseous, liquid or solid state; the reaction is preferably effected in the presence of 5-20% by weight of water based on the silicate reactant and continued until 7 to 25 parts by weight of carbon dioxide per 100 parts of silicate are taken up. Termination of carbonation is indicated by abatement of exothermic reaction heat.ALSO:A carbonated diatomaceous calcium silicate, employed as a carrier for pesticides, is prepared by reacting a diatomaceous calcium silicate (the reaction product of hydrated lime and diatomaceous earth) with carbon dioxide in the presence of water (see Group III).  The carbonated silicate, which imparts a lower pH to an aqueous solution than the initial silicate reactant, is particularly suitable for base-sensitive pesticides.  A typical dry, wettable powder formulation consists of 47 to 87 parts of the carrier, 15-50 parts of the pesticide, 2 parts of a dispersing agent such as a naphthalene sulphonic acid-formaldehyde condensate and 1 part of a wetting agent such as an alkylphenoxypolyethoxyethanol. Specific formulations referred to comprise 72 parts of the carrier, 2 parts of the sodium salt of a copolymer of maleic anhydride and diisobutylene, 1 part of octylphenoxypolyethoxyethanol and 25 parts of either 1,1-bis-(chlorophenyl) - 2,2,2 - trichloroethanol ("Kelthane," Registered Trade Mark), dinitro - (1 - methylheptyl) - phenyl crotonate ("Karathane," Registered Trade Mark), or o,o - dimethyl - 5 - (1,2 - dicarbethoxyethyl) - dithiophosphate ("Malathion," Registered Trade Mark).

Title: Winding drum
IPC: B66D1/30
Filed: 1925-10-23
Abstract: 259,769. Reid, W., Reid, R. H., and Reid, W. Oct. 23, 1925. Reels.-A winding-drum which is adapted to receive two falls of rope to be wound thereon in opposite directions comprises a body portion 1 secured to a driving-shaft 2, end portions 3, 4 freely mounted on the shaft, to each of which is connected an end of one fall of rope, and camoperated means within the drum whereby, depending on the direction of rotation of the drum, one end portion is coupled to the body portion and the other end portion is uncoupled from the body portion. Helical cam paths 5 of like hand, pitch, and diameter are formed on the inner faces of the parts 3, 4, and each ends in an abrupt fall 6. An endwise movable rod 7 passes freely through the drum 1 parallel to the shaft 2 and is at the same radial distance from it as the cam paths 5. A detent lever 8, pivoted at 9 and urged outwards by a spring 10, is mounted on each part 3, 4 and engages a fixed stop 11. A pin 12 on each lever 8 projects through a slot 13 concentric with the pivot 9 in the part 3 or 4, and is engaged by one of the ropes on rotation of the drum. If each rope is unwound, on rotating the body 1, one of the parts 3, 4 will also be turned by the engagement of the rod 7 with the wall 6. The rope then commences to wrap on the moving end part and, engaging the pin 12, moves the lever 8 clear of the stop 11. At the end of the wind, if the direction of rotation of the shaft 2 is reversed, the rope is unwound. When unwinding is nearly completed, the lever 8 is freed and is moved by the spring into contact with the stop, thus arresting the rotation of the end part. As the body 1 continues to turn, the rod 7 ascends the cam path on the arrested end portion and is moved endwise until its other end is in position to engage the wall 6 of the other end part. Further rotation in the same direction causes the winding of the other rope.
