A solid formulation of an agrochemical is prepared by forming a melt containing at least one agrochemical and at least one thermoplastic binder having a melting point or glass temperature of greater than 35.degree. C., briquetting the melt by dividing it into drops in a first step and solidifying these drops by cooling in a second step, characterized in that the melt additionally comprises a liquid non-volatile solvent for the agrochemical.

A rigid open-cell plastic foam body useful, for example, as a filter is prepared by mixing equal parts of a diglycidal ether of bisphenol A epoxy resin and the reaction product of an excess of a polyfunctional amine and a polyfunctional fatty acid with two parts of water while avoiding the entrapment of air in the mixture to form an emulsion in which water is the continuous phase, casting the emulsion in the desired form and curing the emulsion.

A solid bipropellant grain having a specific impulse of over 275 seconds prising a slotted, single perforate, internal burning oxidizer grain and adjacent pressed lithium aluminum hydride plates in which the greatest surface is exposed to the flow of the combustion products of the oxidant.

Polymeric compositions based on, e.g., polyethylene or poly vinyl chloride containing ultra-fine metal flakes produced by grinding metals in an organic liquid are electrically conductive. The specific resistance can be decreased in some cases to less than 10.sup.-.sup.1 ohm. cm.

The propellant grain of a rocket motor is improved by providing flame resant adhesive strips longitudinally on the outer periphery of the grain for centering the grain in the motor case and to allow for equal distribution of chamber pressure around the exterior of the grain. The results are also enhanced by addition of a slotted pressurization ring at the forward end of the grain.

A solid ovoscope having an outer plastic shell and an inner refringent body for use in visualizing amniotic contents and fetal assessment during pregnancy.

An abrasive solid is composed of an organic high polymer matrix and an abrasive material dispersed in the matrix to form a solid mass, whose cutting resistance is from 2 kgf (19.6 N) to 15 kgf (147 N) so that the abrasive solid is severable into two with use of a knife, cutter or the like tool and highly effective to remove rust from any target article. Two or more of such abrasive solids each having these properties are consolidated to form an integral piece that can be trimmed into any desired...

Solid particles containing 10 to 90 parts by weight of a dihydroxy compound and 10 to 90 parts by weight of a carbonic acid ester are disclosed. Also disclosed is a process for the production of these particles, an apparatus suitable for the process and a method for their use in production of polycarbonate by transesterification of carbonic acid esters with dihydroxy compounds.
