Abstract: A process of encapsulating water-immiscible material within discrete capsules of polyurea without addition of a second reactant, whereby hydrolysis of an isocyanate mo- nomertoform an amine takes place, which in turn reacts with another isocyanate monomer to form polyurea, which comprises the steps of

(a) providing at room temperature, a dispersion of

(i) a plurality of water-immiscible phases, each phase comprising the water-immiscible material to be encapsulated and at least one organic polyisocyanate in
(ii) an aqueous phase comprising a solution of water, a surfactant and a protective colloid; and

(b) heating and maintaining said dispersion in a temperature range of about 40° C to about 90° C, whereupon said water-immisicible material is encapsulated within discrete polyurea capsuler enclosures directly usable without further separation or purification.

Abstract: The present invention relates to a flame retardant mixture of a dialkylalkanolaminoalkylphosphonate and a poly(oxyor- ganophosphate/phosphonate) flame retardant which finds utility, for example, as a flame retardant in polymers containing urethane linkages. It confers food flame retardancy on the polymer without any substantial reduction in its heat distortion temperature.

Abstract: The invention is directed to a process for recovering elemental phosphorus values from phosphorus-containing waste materials. The process comprises reducing the size of the solid particulate materials of the sludge and forming a uniform homogenous sludge which is filtered through a high-pressure thin-cake filter resulting in a filtrate high in phosphorus values.
The invention also discloses a pump retrieval means for retrieving the sludge from contaminated disposal areas and a preconditioning dewatering means for thickening and clarifying the sludge prior to comminuting the solids contained therein and filtrating to recover the phosphorus values contained therein.

Abstract: A process for the production of a semiconducting catenated phosphorus film characterised in that it comprises sputtering a thin film thereof onto a substrate is disclosed.
The present process may be applied to the production of semiconductor devices. Referring to the accompanying illustrative drawing, a sputtered film 22 may be used in a sandwich configuration on a glass substrate 24 with a metallic lock contact 26 and metal dot top contacts 28.
For example, amorphous and polycrystalline films of KP 15 may be formed by RF diode sputtering targets of KP 15 and excess phosphorus in an argon phase. Substrate temperatures up to 280-300°C provide amorphous films. Higher temperatures provide microcrystalline or polycristalline films. These films have high resistance and may be used as the insulator in MIS devices employing III-V semiconductors. Co-sputtering with nickel increases the conductivity of the films from approximately 10 -10 (ohm-cm)- 1 to 10- 2 (ohm-cm) -1 ; only reduces the optical gap by 0.2 eV; and reduces the activation energy from 0.8 eV to 0.2 eV; the nickel content varying from 5-15%. Substrates include glass, silicon, tantalum, stainless steel, gallium phosphide and gallium arsenide, and glass metallized with metals, such as titanium, nickel and aluminium. Double diode electrical characteristics have been observed in devices formed on metallized glass substrates having co-sput- . terred thereon thin film polyphosphides and nickel with nickel and titanium top contacts.
The present invention represents an advance over the prior art.
