According to the invention, the process consists in treating high fat-content waste with 3...10% by weight mineral acid at a temperature of 80...100°C, for 15...30 min, to obtain a suspension having a pH value of 3.5...4 which is further treated with 5...20% raw biofuel obtained from vegetable waste, while stirring, the proteic suspension is separated and the solution of fat matters is treated with 0.3...1% by weight, as related to the solution of fat matters, an alkaline hydroxide dissolved in methanol, at the temperature of 60...70°C for 45...60 min, the raw glycerol is separated by decanting from the raw biofuel which is subjected to purification and, after volatile removal is filtered through a granular layer, finally resulting a biofuel.

Title: Indicator for bolt pretension control
Inventor: BUDESCU MIHAI
IPC: F16B31/02
Filed: 2011-03-17
Abstract: The invention relates to an indicator for the pretension control of high-strength bolts used in metal structure joints. According to the invention, the indicator comprises an outer ring () manufactured from a composite material, having an inner surface partially machined as a frustum of a cone, having a generatrix with an angle (), and a ring-shaped washer () manufactured from high-strength steel, inserted into the outer ring (), the washer () having an outer surface machined as a frustum of a cone having a generatrix with an angle (), the outer ring () being provided with some recesses () made in the outer side, the number of the recesses () and the radius () thereof is determined depending on the diameter of a bolt and the property class, and the required final pretension force, respectively, a distance () between the ring-shaped washer () and the joined pieces is diminished by tightening the bolt, the ring-shaped washer () comes into contact with the joined pieces when the final pretension force is reached and the outer ring () is removed.

Patent SA-517381568-B1 (SA)
Title: System For Protection Of Dry Type Transformers
Inventor: ELISABETH LINDELL
Filed: 2017-05-21
Abstract: A system (100) for transient over voltage protection of a three-phase transformer. Two surge arresters (120, 122, 128, 130, 134, 136) are series connected across each winding (102, 104, 106) of the transformer and the center point connection (124, 132, 138) of the two surge arresters is electrically connected to a middle location of the winding (102, 104, 106). Three additional surge arresters (114, 116, 118) are electrically connected from each phase to ground in the case of either a delta or Y connected transformer; and/or connected from a neutral point to ground in the case of a Y connected transformer. The system (100) allows for all of the surge arresters (114, 116, 118, 120, 122, 128, 130, 134, 136) to be packaged as an integrated surge arrester system (200) to minimize induced transient over voltages and high stresses on the transformer winding due to internal resonances. See Fig. 5.
