Title: Filtration of particles from water entering tubular drain - by surrounding drain with circular sleeve of knitted synthetic cloth
IPC: E02B11/00
Filed: 1976-07-02
Abstract: Soil particles >100 mu are filtered from water entering a tubular drain by a sleeve of knitted cloth. The tubular drain is flexible and is undulating with peaks alternating with hollows in the longitudinal direction, the hollows having holes for the water to pass through. A sleeve made of a cloth of extensible, creped synthetic threads covers the tube. The sleeve is knitted with a dia. smaller than that of the tube so that when it is pulled over the tube it stretches to form undulations corresp. to the hollows in the tube and is continually under tension. The sleeve is knitted using a stitch that makes the cloth ladderproof and prevents it becoming unknitted. Sleeves of knitted cloth are made in lengths of >=50 m. to fit over drains of the same length. Particles >=100 mu, in size are filtered out by the cloth sleeve, but those of =25 mu pass through into the tubular drain. Used for filtering fine silts and soil particles from water entering field drains. Filter prevents the tubular drains from becoming clogged with large soil particles but allows smaller particles through.

Title: Increasing fungicidal activity of dithiocarbamate salts - e.g. maneb by combining with vinyl acetated polymer
Inventor: BARER SOL J
IPC: A01N57/00
Filed: 1977-01-19
Abstract: In a new procedure for improving the fungicidal action of dithiocarbamate salts, the salts are used in combination with a larger amount of a vinyl acetate polymer. The ratio of vinyl acetate polymer to dithiocarbamate salt is pref. ca 1:1 to ca 30:1 w/w. The vinyl acetate polymer forms a film which improves contact of the dithiocarbamate with the leaf surface and increases resistance to removal by weathering. The vinyl acetate polymer when applied in the form of an emulsion has good spreading properties and rapid set, and the film formed is soft, flexible and weather-resistant. Examples describes biological testing of dithiocarbamates in combination with vinyl acetate polymers. Thus with tomato plants artificially infected with Phytophthora infestants and sprayed with maneb (100ppm) + polyvinyl acetate 202A (600ppm), 77% inhibition of the fungus is obtained when the plants receive 25.4mm of rain after 4 hrs. whereas only 51% inhibition is obtained with maneb (100ppm) is applied without polyvinylacetate.

Title: Animal feeds from sugar beet pulp - by mixing the pulp with high solids sugar soln. and pressing
IPC: C13B15/00
Filed: 1977-02-21
Abstract: Animal feeds are prepd. from forage plant, such as lucerne, sugar beet or their by-products, by lowering their water-content in a process in which the starting material is mixed with 12 wt.% of an aqueous sugar solution containing >=30 wt.% of dry matter and the mixt. is then pressed. The product is storage stable, the stability depending upon the final water content. The process is economical on energy, it allows supplementary extractions of sugar, there is no loss due to combustion in driers, and the forage value can be increased by the incorporation of crushed straw at the same time as the sugar soln. Typically, the aq. sugar soln. is molasses and the prod. is pressed in a cylinder crusher by two successive operations. In an example, 250 tonnes/day sugar beet pulp, contg. 50t dry matter, was mixed with 9t/day molasses in a continuous process. The mixt. was passed to two sugar cane-mills which gave 114t/day of pulp contg. 41.8% dry matter. This product could be passed to a drier to give 55t/dau of pulp containing 47.6t dry matter.
