Definitions

  • Stop leak preparations have heretofore involved a mixture of solid comminuted stop leak ingredients in a liquid carrier, the same being sold in suitable jars or other containers. After a period of time, the solid matter is prone to settle or pack on the bottom of the container, thus involving some difiiculty in emptying the contents thereof into a cooling system radiator or the like where it is to be employed.
  • the solid ingredients are molded into a pellet 1 for immersion in a carrier liquid 3 other than water, within a suitable container such as a jar 5 with a screw cap 7.
  • the pellet material is held together by a binder which is insoluble in the carrier liquid but soluble in water.
  • a binder which is insoluble in the carrier liquid but soluble in water.
  • Such binder in the embodiment of the invention illustrated, may be in the form of a coating 9. Not only does the binder, in the form of a coating, tend to hold the pellet against disintegrating, but the buoyant effect of the carrier liquid serves to cushion the pellet against breakage from shock or blows against the container during shipping or handling.
  • the ginger root flour is mixed with sufiicient soluble oil to produce saturation thereof, following which the flour in its oil saturated condition is compressed and extruded and the extrusion cut into pellets.
  • These pellets are then put through a bath of polyvinyl alcohol as a binder to produce a coating of a thickness preferably of the order of three or four mills.
  • Such binder is soluble in water but insoluble in oil, and is obtainable on the market nited States Patent 0 I 2,935,189 Patented May 3, 19 6l] either under the trademark Elvanol put out by the D11 pont Co. or Vinol, a product of the Colton Chemical Co. a subsidiary of the Air Reduction Co.
  • the coated pellet is then placed in a container such as the screw cap jar containing suflicient soluble oil therein to substantially fill the jar upon immersion of the pellet therein.
  • the maximum permissible size of the pellet is controlled by the radiator opening or other opening through which the pellet is to enter the cooling system in which it is to be employed, and it will be appreciated that upon removal of the cap from the container and pouring the contents thereof into the radiator opening for example, the pellet will be guided into such opening by the flow of oil from the container. No preliminary mixing or stirring is required and the entire contents will be disposed of in the one pouring.
  • the binder may be incorporated into the pellet, in which case the binder will be dispersed throughout each pellet, instead of over the surface thereof as a coating.
  • the binder concentrated sal soda obtainable under the trade name Con-Sal.
  • the pellets are packaged in oil, preferably a soluble oil, which permeates and saturates the pellet without causing disintegration thereof, due to the presence of the binder which is oil-insoluble.
  • the dried root may be saturated with the binder prior to grinding the root into flour.
  • the binder upon immersion of such pellet in the water of a cooling system, the binder will dissolve and permit the pellet to disintegrate, thereby freeing the oil saturated particles of the ginger root flour for dispersion throughout the cooling system to seek out and seal such leaks as might exist.
  • a stop leak package for a cooling system comprising stop leak material held together in pellet form by a water-soluble binder, a container, a liquid in said container which may advantageously be added to such cooling system and in which liquid said binder is insoluble, and at least one pellet in said liquid, said package offering protection to said pellet and permitting dispensing of said pellet with ease into the opening of a radiator or like opening of a cooling system.
  • a stop leak package comprising stop leak material held together in pellet form by an oil-insoluble watersoluble binder, a container, oil in said container, and at least one pellet in said oil, said package offering protec tion to said pellet and permitting dispensing of said opening of a cooling system.
  • a stop leak package comprising stop leak material held together in pellet form by'an oil-insoluble watersolnble binder such as polyvinyl alcohol, a container, a soluble oil in said container, and at least one such pellet in? said oil, said package offering protection to said pellet and permitting dispensing of said pellet with, easeinto the opening of a radiator or like opening of a" cooling system.
