Abstract: APPLICANT:  AB VOLVO PENTA            TITLE:      BOAT PROPELLER DRIVE UNIT     ABSTRACT OF THE DISCLOSURE        In an outboard drive unit for boats, the drive shaft housing is swingable by means of hydraulic cylinders for trimming and tilting. One end of each cylinder is pivotally journalled in the shield of the drive unit, whereas the opposite cylinder ends bear against abutment surfaces on the carrier fork shanks conventionally supporting the drive shaft housing. An intermediate member, pivotally connected to the cylinders via pivot pins, is pivotally suspended in the carrier fork, moving along with it during trimming and tilting. A pivot pin fixed into the intermediate member constitutes one part of a mechanical latch means, the other part being formed of a latch hook (not shown) rotatably journalled on the carrier forks. The latch means is thereby completely disengaged upon propeller thrusts during forward travel.

Abstract: Abstract Two Stage Rotor Assembly With Improved Coolant Flow A spacer extends between and engages the rear face of a first disk and front face of a second disk of co-rotating rotors of a two stage turbine.  The spacer engages the disks radially inwardly of the blade root slots of each disk and defines an inter-mediate cooling air compartment between the disks, radially inward of the spacer.  Each disk includes blade root slots, each having a blade root disposed therein and defining a cooling air passageway across each slot from the front to rear face of each disk.  Cooling air from a compartment upstream of the first disk is directed downstream through the passageways across the slots and thence radially inwardly into the intermediate compartment between the disks.  From the intermediate compartment the cooling air travels radially outwardly and then axially through the cooling air passageways across the second disk blade root slots. Thus, the same mass of cooling air from upstream of the first disk is used to cool the rims of both disks and the blade roots disposed in the slots of both disks without the air having to pass through axial holes through the first disk, thereby eliminating the need for such holes and increasing the strength of the disk.  In a preferred embodiment a portion of the cooling air passing through the slots of each disk is directed radially outwardly into hollow airfoils which are integral with the blade roots.

Abstract: ABSTRACT OF THE DISCLOSURE An air assisted spray nozzle having a nozzle body formed with an elongated mixing and atomizing chamber having an air inlet orifice communicating with one end of the chamber, a liquid inlet orifice communicating with a side of the chamber, and a nozzle tip having a discharge orifice located at the end of the chamber opposite the air inlet orifice. Transversely directed streams of pressurized air and liquid enter and converge in the mixing and atomization chamber of the nozzle body causing preliminary atomization of the liquid, which is thereupon directed under the force of the high velocity air stream out the discharge orifice and against a deflector flange of the nozzle tip which further atomizes the liquid and directs it into A well-defined flat fan spray pattern with uniform distribution and liquid particle size.  To enhance preliminary atomization, the mixing and atomizing chamber has an inwardly extending liquid impingement post in diametrically opposed relation to the liquid inlet orifice, and to facilitate further atomization and controlled direction of the discharging spray the deflector flange defines an arcuate shaped guide surface which is substantially wider than the width of the discharge orifice and has a terminal lip transversely offset from the discharge orifice.

Abstract: TIELINE CONTROL ABSTRACT OF THE DISCLOSURE          A method and apparatus of obtaining a correction value for the deviation between an actual power usage and a desired target power usage during a time period, comprises dividing the time period into a plurality of time segments, measuring, after each time segment a fraction of time into each time period, and multiplying the fraction by the target power usage to obtain a value corresponding to the fraction of the total power usage during the cycle.  Also after each time segment, the total amount of power which has actually been used is measured and a difference is taken between the total amount power used from the beginning of the period and the fraction of the target power usage from the beginning of the period.  This value is then divided by the amount of time remaining in the cycle to obtain the correction value. The correction value can be processed and utilized to control an  internal generator for the plant or to take other corrective action.

Abstract: ABSTRACT            TREATING ALUMINIUM WITH CHLORINE      When molten aluminium is treated with chlorine to remove alkali and alkaline earth metals and hydrogen, there is formed a brittle oxide crust which does not protect the metal from oxidation.   This problem is solved by admixing with the chlorine a minor proportion of a gaseous compound of fluorine, preferably sulphur hexafluoride, which can form alkali or alkaline earth metal fluorides in the presence of molten aluminium.          The proportion of sulphur hexafluoride to chlorine gas is preferably from 0.01 to 1Ø   Ingots cast using the treated metal are free of oxide patches on their surface.
