Title: Finely comminuted water-soluble materials and aqeous suspensions thereof
Inventor: ENEVER J
IPC: C09K23/00
Filed: 1980-08-26
Abstract: Water-soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water-soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water. The viscosity of aqueous suspensions of comminuted solid is thereby stabilised.The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives.With crystal-growth inhibitors such as water-soluble polysaccharide derivatives, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes or sulphonated polymers the preferred deflocculant, which should be different from the crystalgrowth inhibitor, may include water-soluble polysaccharide derivatives, polyacrylic acid, polyvinyl pyrrolidone, sodium lignosulphonate and/or a salt of a condensate of naphthalene sulphonic acid with formaldehyde.
Patent ZA-844643-B (ZA)
Title: Porous mullite
Inventor: SPERONELLO BARRY K
IPC: C04B38/00
Filed: 1984-06-19
Abstract: Clay convertible by thermal treatment into crystalline mulite and silica is formed into green coherent bodies of desired size and shape such as for example, microspheres, pellets or honeycombs. The bodies are then calcined to convert the clay into a mixture of crystalline mullite and silica, thereby also hardening the bodies. Without destroying the form of the bodies, e.g., without grinding and without causing the bodies to decrepitate, pores in the size range of about 150 to 350A are formed by selectively leaching silica from the bodies. The porous mullite bodies retain porosity at elevated temperatures and are useful, for example, as catalyst supports and contact materials. Pore structure in the meso- (100-600A diameter) and macro- (600-20,000A diameter) size ranges may be controlled.

Title: Apparatus for spraying plant-protective agents
Inventor: GRABER ALFRED
IPC: A01M7/00
Filed: 1985-07-12
Abstract: An apparatus for spraying plant-protective agents comprises a spray head having a motor, a spray plate mounted on the driving shaft of the former and a first container which is fastened to a lance. The container is connected via a connecting pipe line with a nozzle in the vicinity of the center of the spray plate. Diametrically opposite the mouth of the connecting pipe line in the container, a supply hose is connected with the first container which hose connects the latter container with a portable second container. Thereby, the relatively small first container can be refilled from the substantially larger second container. A large area can, therefore, be sprayed without having to handle the plant-protective agent. This reduces the danger of coming into contact with the plant-protecting agent. The apparatus is particularly suitable for the spraying of insecticides and fungicides.

Title: Method for fabricating microactuator for inkjet head
Inventor: KIM IL
IPC: H01L41/39
Filed: 1999-02-10
Granted: 2001-01-10
Abstract: Initially, a lower electrode 3 (Fig.10A) and an oxide piezoelectric sheet 4 is laminated over a vibrating plate 2 with an integral chamber plate 1. A photoresist film is coated over the upper surface of the piezoelectric sheet. Some film is removed through baking and exposure of light via a patterned mask. The oxide piezoelectric sheet is etched, using the remaining film as a mask, to form oxide piezoelectric elements of a predetermined pattern. The resulting structure is rinsed to remove the film completely. An electrode layer (Fig.10B) is coated to a predetermined thickness over the entire exposed upper surface of the structure, i.e. the upper surfaces of the oxide piezoelectric elements, and the exposed upper surface portions of the lower electrode. Another photoresist film 6 (Fig.10C) is coated over an upper surface of the electrode layer, and portions thereof not covering the oxide piezoelectric elements are removed by rinsing (Fig.10D). Unnecessary portions of the electrode layer are removed by etching while using the second film remaining on the electrode layer as a mask to form upper electrodes 5 (Fig.10E). The photoresist film left on the upper electrodes is completely removed (Fig.10F) to form the microactuator. Several other methods of forming the microactuator are disclosed (Figs. 1A-9D,Figs.11A-12D). For example, the chamber plate maybe etched and patterned to form chambers therein following the formation of the oxide piezoelectric elements (Figs.3A-D).
