  • Patent number: 11247819
    Abstract: A biodegradable polymeric sheet may be configured to undergo biodegradation on the ground responsive to an exposure to free air and natural day light. The biodegradable polymeric sheet may include a first layer comprising polysaccharide at a weight % of between 15% to 50% and a polyester matrix, the first layer is configured to form a water barrier when in contact with water; a second layer comprising a polysaccharide at a weight % of at least 40% and a polyester matrix; and a third layer comprising polysaccharide at a weight % of between 15% to 50%, a polyester matrix and an additive configured to accelerate disintegration of the polymeric sheet when exposed to natural day light, the third layer is configured to form a water barrier when in contact with water.

  • Patent number: 10086940
    Abstract: A method of delivering over the air, shelled portions of fluids or granular substances containing effective ingredients, to a target, includes the following stages: selecting a type and a size of the shelled portions containing the required effective ingredients, based on mission parameters and physical data of a scene containing the target; conveying the shelled portions to a delivery point, based on the mission parameters and the physical data; and ballistically delivering the shelled portions towards the target, wherein the shelled portions comprise fluids or granular substances covered by shells that provide the shelled portions a ballistic coefficient that is significantly higher than a ballistic coefficient of similar portions without the shells.

  • Patent number: 9884471
    Abstract: Disclosed is a biodegradable sheet prepared from biodegradable material, a process for preparing the biodegradable sheet and uses thereof. One of the disclosed uses of the biodegradable sheet is in the preparation of a flexible liquid receptacle. Disclosed also is a flexible liquid receptacle arranged as an array of several receptacle units that are attached to one another and that may be detached from one another by tearing along a perforated line created between each two receptacle units. The disclosed array may also include a hanger, thus allowing the array to be hung from any appropriate means. Further disclosed is a biodegradable sheet including at least one layer comprising about 15-25% w/w PLA and about 75-85% w/w PBSA.
