Abstract: A deflection circuit comprises a deflection correction circuit (Vs) with a controllable active voltage source (Vs) arranged in a loop formed by a deflection coil (Ld), an S-capacitor (Cs), and a flyback capacitor (Cf). The voltage source (Vs) receives a further power supply voltage (Vb2) and a modulating signal (M) to supply a modulating voltage (Vm) varying in response to the modulating signal (M). The active voltage source (Vs) comprises a switching element (S2) which is switched on and off with a frequency which is substantially higher than the deflection frequency to possibilitate waveforms of the modulating voltage (Vm) with a frequency content which is substantially higher than the deflection frequency such that any desired waveform can be generated within the deflection period (Td).

Abstract: Reinforced plastic pellets comprise thermoplastic material and reinforcement particles that are less than 15% of a total volume of the pellets, and at least 40% have a thickness of less than 50 nanometers. A manifold (56) has at least two spaced valve gates (64) that are independently opened and closed as directed by a controller (68) to selectively communicate the manifold to a cavity. A primary injection pressure is applied to the plasticized pellet material in the manifold (56) to fill the cavity through sequential opening and closing of the gates (64). A lower secondary injection pressure is applied to the material in the manifold to continue filling the cavity. The gates are closed to seal the manifold from the cavity when the cavity is filled. The material is held within the manifold in compression by the valves while the cavity is open to prevent expansion of the material.

Abstract: A method for mixing a pulverulent material in a main gas flow with a view to achieving uniform distribution of the pulverulent material. The turbulence in the main gas flow is increased in a vortex-generating zone. The pulverulent material is introduced into the main gas flow, in a mixing zone, with a carrier gas flow whose net motion during introduction is essentially opposite to the main gas flow. The mixing zone is positioned downstream of the vortex-generating zone and in the vicinity thereof. The carrier gas flow with the pulverulent material is in a rotational zone given a helical motion, whose axis of symmetry is essentially parallel with the direction of flow of the main gas flow, and is introduced into the mixing zone in the form of a divergent hollow cone. A device for carrying out the method comprises a gas duct (1) for the main gas flow with vortex-generating means (4) and an introducing means (11) for introduction of pulverulent material in dispersed state into a carrier gas flow. The introducing means (11) comprises a cylindrical pipe (13) with an open and a closed end, a tangential inlet (17) in the vicinity of the closed end of the cylindrical pipe (13), and a divergent axial outlet (18) at the open end of the cylindrical pipe comprising a truncated conical jacket (14) and a centered insert (16) adjacent to the axial outlet so adapted that an annular opening (19) forms between the truncated conical jacket (14) and the insert (16).

Abstract: The blades of the propellers used in the antifrost and/or multiple-use systems, that is, those which also perform spraying of insecticides or other substances, are generally made of fibreglass and are rigidly secured to a steel hub fitted in a permanent or pivoting manner in a rotating shaft. In the invention, each blade of the propeller is made of extruded aluminium alloy with rigorous respect to the aerodynamic profile, so that it is extremely light, or it is made of another metal and is fitted about an arm which is not secured rigidly to the hub, but instead can oscillate, within a certain angle and independently of the other blade, in a plane passing through the axis of rotation of the propeller. In this way, each blade during the rotation takes up a position according to the resultant of the centrifugal force and the axial thrust and therefore is not subject to any bending moment. Furthermore, the blade itself can easily be arranged in the actual arm, possibly varying its length, at different heights and at different coupling angles, so as to vary the power and the flow characteristics of the propeller, in terms of these two new parameters as well. A spring system regulates the oscillation of the blade. The material of which the blade is made furthermore allows easy varying of the twist, as well as the length of same. <IMAGE>

Abstract: A bearing surface of a subsea foundation has a low-resistance coating such as an aerogel, an aero-clay or a polymeric film. When the foundation is installed, the bearing surface is embedded in the seabed soil using the low- resistance coating to reduce resistance to movement of the bearing surface relative to the seabed soil. The coating may then dissolve or fragment away from the bearing surface or transform into a higher-resistance state while remaining on the bearing surface. These mechanisms degrade a resistance-reducing property of the coating to increase resistance to movement of the embedded bearing surface relative to the seabed soil. Suction may be applied to the foundation before or after the resistance-reducing property of the coating has substantially degraded.

Title: Method of obtaining alpha-/1-methylethyl/-3,4-dimethyloxyphenylacetonitrile

Filed: 1988-04-06
Abstract: New process for the synthesis of the  alpha -(1-methylethyl)-3,4-dimethoxyacetonitrile of formula <CHEM> intermediate in the synthesis of the drug internationally known as verapamil. The process starts from the isobutyryl-3,4-dimethoxybenzene of formula <CHEM> which, by means of the Darzens condensation, gives an epoxyester which, by alkaline hydrolysis and subsequent decarboxylation, gives the  alpha -(1-methylethyl)-3,4-dimethoxybenzeneacetaldehyde. This product is reacted with hydroxylamine so obtaining the corresponding oxime that, by dehydratation, gives the nitrile of formula I.
