Title: Diaphragm pumps
IPC: F01L25/04
Filed: 1978-10-11
Abstract: Diaphragm pumps are used for pumping liquids and comprise rods passing through a housing for effecting diaphragm return movement. This invention provides a novel diaphragm pump which avoids the use of those rods. The novel pump has an air chamber (26) and a pumping chamber (30) separated by a composite diaphragm (16, 18). Feeding compressed air to the air chamber (26) moves the diaphragm to effect a pumping stroke. The return stroke of the diaphragm is achieved by exhausting the air chamber (26) while feeding compressed air to a further air chamber formed between first (16) and second (18) membranes of the composite diaphragm. The area difference between the membranes is sufficient to make the composite membrane (16, 18) self-erecting, to draw fluid into the pumping chamber (30) ready for the next pumping stroke of the diaphragm.

Title: Process for recovering methacrylic acid
IPC: C07C51/00
Filed: 1980-03-14
Abstract: In an oxidation process for coverting methacrolein to methacrylic acid, the product methacrylic acid is recovered by cooling and condensing the effluent from the oxidation. The condensed effluent, which contains methacrylic acid and water as the major components along with by-product acetic acid, a minor amount of unreacted methacrolein and impurities, is extracted with a suitable solvent, preferably a ketone- aromatic mixture, most preferably a methyl n-propyl ketone-toluene mixture in order to reject water and impurities. Substantially dry crude methacrylic acid including by-product acetic acid is separated from the solvent by distillation of the rich solvent. Water and the solvent are taken overhead, condensed and separated as solvent-rich and water- rich phases. The recovered solvent is returned to the extraction column. A portion of the solvent-rich phase is distilled to recover methacrolein, while the water-rich phase is sent to a stripping column for recovery of residual solvent. Water is withdrawn from the bottom of the stripping column and reused or discarded, as desired.

Title: Method for producing photosensitive printing plate precursor
IPC: G03F7/115
Filed: 1980-03-17
Abstract: A light-sensitive material ("precursor") used to produce a printing plate is known to comprise a support bearing a photosensitive layer and having an outer surface which is matted with particulate matting agent, e.g. silica or glass beads, so as to reduce the time needed for vacuum contacting of the plate made from the precursor before imagewise exposure. According to the present invention, to improve the durability and the quality of reproduction, the outer matted layer is provided by coating a composition in which the particulate matting agent is stably dispersed but has poor affinity for the liquid of the composition so that as the liquid is evaporated the particles are pushed to the surface of the material and are there weakly bonded as minute protrusions; development removes the coatings from the support entirely in non-image areas and removes the protruded particles in image areas. Suitable matting agents are of polyethylene, polypropylene, polyethylene terephthalate, cross- linked vinyl polymers and copolymers of ethylene and propylene or vinyl acetate. Photosensitive compositions can comprise a diazo resin, o-quinone diazide, photosensitive diazide or polymeric compounds.

Title: Purifying graphite
Inventor: ATKINSON ALAN WILLIAM
IPC: C01B31/04
Filed: 1982-10-07
Abstract: Expanded graphite compounds obtained by treating graphite with sulphuric acid under oxidising conditions, and washing the product with water to replace with water the free sulphuric acid present in it, contain bisulphate ions which are not removed on flash heat expansion (exfoliation) and are responsible for the slight corrosive capacity of material made by compacting the exfoliated stuff. Reduction of such corrosion can be achieved by subjecting the pre-exfoliated water- washed graphite compound to a further treatment with water, in which there is employed water at a temperature above 100 DEG C under superatmospheric pressure or water at a temperature above 30 DEG C with a content of dissolved nitric acid or a nitrate.
