Title: Vincamine and 14,15-dehydro-vincamine prepn
Inventor: VITALI ROMANO
IPC: C07D461/00
Filed: 1982-10-25
Granted: 1987-01-14
Abstract: Process for the prepn. of vincamine (I) or 14,15-dehydro-vincamine (apovincamine) by oxidn. and then rearrangement of a soln. of vincadifformine or tabersonine respectively, is characterised in that a protecting agent is added to the starting soln., which is in a polar solvent at a temp. equal to or below 5 deg.C, then the oxidn. is effected with permaleic or peracetic acid, and when addn. of peracid is complete, the rearrangement is effected by heating the reaction mixt. at 20-50 deg.C. The protecting cpd. may be a copper salt, added in quantities such that the ratio of starting cpd. to copper salt is 1-10:1. The protecting agent may also be oxalic acid, which is added to the initial soln. at -5 deg.C, followed by addn. of the peracid at -2 deg.C. The polar solvent used is a lower aliphatic alcohol pref. methanol. The pH after addn. of the peracid is 6-2.5. Permaleic acid may be prepd. in situ from maleic anhydride and hydrogen peroxide. The peracid is added at -5 to 0 deg.C. At the end of the reaction the copper salt is sepd. When permaleic acid is used the precipitated copper salt is filtered off. When peracetic is used, the copper salt may be removed by chelation on a resin, such as a macroporous polystyrene polymer having amino-phosphonic, amino-diacetic or amino-oximic functional gps. The rearrangement is effected by heating at 30-50 deg.C, pref. 35-40 deg.C. Before or during this stage, a reducing agent, such as sodium metabisulphite, sulphur dioxide or sodium, may be added, which aids later purificn. Prepn. of vincamine used for the treatment of cerebrovascular troubles.

Title: Hot-top for upper part of ingot mould
Inventor: VALLAK ENN
IPC: B22D7/10
Filed: 1981-05-22
Granted: 1990-06-21
Abstract: An ingot mould has a hot-top positioned inside its upper part which comprises a plate of material capable of withstanding contact with molten metal poured into the mould. The plate is of less thickness than the mould wall thickness and is received in a recess in the inner wall of the mould top so that its surface is flush and aligned with the inner surface of the mould. The plate forms a closure wall which separates the interior of the recess from the interior of the mould. Used for casting Fe and steel ingots. Pipe formation in the ingot is limited, Owing to thermal expansion of the inner wall of the hot top during casting, the inner wall is moved off of the ingot, without any external manipulation so that a gap is formed which acts as a very efficient thermal insulation. This also reduces contamination of the ingot. The hot-top construction is simple and facilitates manipulation for maintenance and repair.

Title: Coarse screening grid with moving teeth - for removal of detritus from waste water and sewage
IPC: E02B/
Filed: 1975-09-24
Granted: 1980-09-10
Abstract: A coarse screen grid unit for sepg. the large solid detritus from waste water and sewage, is inclined to the rear at an angle of the order of 30 degrees to avoid jamming by rags, etc. The rods of the grid have their upper portions extended towards the rear by curved parts. The links of the endless chain are fitted with teeth which pass between the rods of the grid. The chain passes over lower and upper toothed rollers, a castellated drum is mounted on the same shaft as roller and receives the rods as they pass over the summit. This ensures that the air-gap between the rods is maintained. and that the summit of the drum presenta smooth surface and allows the detritus to be readily transported into the recipient provided. A peripheral cavity in the drum serves for the passage of the foot of a tooth when one reaches the drum. More flexible and reliable operation of the appts. is achieved by avoiding blockages which can cause loss in working time. To reduce friction, the drum and the rods can be covered with a film of plastic material.

Filed: 1989-10-31
Abstract: A synthesizer is disclosed in which error correction pulses from a phase detector (205) are separated into narrow pulse width and wide pulse width pulses. The wide pulse width pulses are coupled to the loop filter (233,235,237) to enable a rapid charge of the loop filter. The narrow pulse width pulses are filtered by a narrow bandwidth filter (225,226,227) before being applied to the loop filter thus enabling a slow charge of the loop filter. The narrow bandwidth filter is decoupled from the control line but referenced to the control line voltage by a buffer amplifier (259) to preserve the adaptive nature of the loop.
