Abstract: A milk flow device which includes a conduit for transporting a substantially continuous milk flow varying in height up to a maximum height wherein the maximum height is less than a fluid height which would occlude the conduit and interrupt the vacuum level. A first sensor determines the height of a selected section of the substantially continuous milk flow. The first sensor has a predetermined cross-sectional area and defines an opening for passing a milk flow therethrough. The first sensor is located at a predetermined location in the conduit. A second sensor having a cross-sectional area substantially equal to the cross sectional area of the first sensor is spaced within the conduit in a selected direction and a known distance from the first sensor. The second sensor determines that the selected section of the continuous milk flow has traversed the known distance. A conductivity sensor measures the conductivity of the milk.

Abstract: A method for measuring flow rate of a continuous fluid flow is shown. The method comprises the steps of generating a first signal representing a height of the fluid flow having a known cross-sectional area at the first predetermined location and for generating a second signal at a second predetermined location located in a selected direction and at a known distance from the first predetermined location; generating a third signal representing the conductivity of the fluid; receiving the signals and creating a data stream therefrom; calculating an elapsed time for the fluid flow to traverse the known distance; calculating the average conductivity of the fluid; deriving the cross-sectional area of the selected section and compensating the cross-sectional area for variance in conductivity; calculating the volume of fluid flow; and generating an output signal representing the calculated volume of fluid flow.

Abstract: A metal salt solution containing about 6.0 g to about 25 g of sodium hydroxide, about 20 g to about 70 g of ammonia and about 2 g to about 20 g of silver nitrate per 1 liter of water for use as a metal salt solution for forming a metallic mirror surface on a receiving surface is shown. The receiving surface is treated with an activating treatment agent containing stannous chloride and at least one precious metal salt of palladium, gold, silver or the like followed by a concurrent application of the above reacting metal salt solution and reducing agent solution to form a metallic mirror surface on the receiving surface.

Abstract: An open loop feedback control apparatus for a vacuum controlled system for providing vacuum stability within a predetermined range of vacuum levels is shown. The open loop feedback control apparatus includes a vacuum regulator having a diaphragm including a valve member having a valve opening or input port which changes position as a function of the vacuum level within the vacuum system for controllably admitting or bleeding air into the vacuum system to adjust the vacuum level within the vacuum system. A transducer is operatively coupled to the diaphragm for producing an output signal which represents an instantaneous position of any one of the diaphragm valve member, valve opening or input port.

Abstract: A hybrid electric vehicle having alternate fuel sources is shown. The hybrid electric vehicle includes an alternating current to direct current converter for producing and storing a direct current voltage in a direct current voltage storage device. A fuel converter receives fuel in a first state and converts the fuel into a combustible material or a combustible fuel in a second state which is stored in a combustible material storage device. A driving system for transporting the hybrid electric vehicle includes a direct current motor operatively connected to the direct current voltage storage device. The direct current motor is responsive to a stored direct current voltage for driving the driving system in response to a first control signal. A combustible material engine is operatively coupled to the driving system and drives the driving system in response to a second control signal.

Abstract: A method for forming a mettalic mirror surface on an underlay is shown. The method comprises the steps of: adjusting the underlay; applying an activating treatment agent solution to the underlay wherein the activating-treatment agent solution contains about 10 cc to about 44 cc of hydrochloric acid, about 1.5 g to about 5 g of stannous chloride and about 0.001 g to about 0.005 g of a precious metal salt of at least one of a silver nitrate, palladium chloride, gold chloride and platinum chloride per 1 liter of water; and reacting a metallic salt with a reducing agent to form a metallic mirror.

Abstract: An article having at least a portion of the outer surface thereof coated with a metallic mirror surface comprising a reactant formed by reaction of an activating treatment agent containing stannous chloride and at least one precious metal salt of palladium, gold, silver and platinum reacted with a reacting metal salt and a reducing agent is shown. The metallic mirror surface having a colored metallic luster formed on at least a portion thereof is also shown.

Abstract: A method for forming a metallic mirror surface on a receiving surface, substrate or article is shown. The method comprises the steps of cleaning the receiving surface to be coated with a metallic mirror surface; spraying on the receiving surface an activating treatment agent containing stannous chloride and at least one precious metal salt of palladium, gold and silver or the like; and separately spraying concurrently on the receiving surface, a reacting metallic salt solution and a reducing agent solution to form the metallic mirror surface. The method may include the step of treating the receiving surface with a water wash treatment. The activating treatment agent may be in a solution form and contain about 10 cc to about 44 cc of hydrochloric acid, about 1.5 g to about 5 g of stannous chloride and about 0.001 g to about 0.005 g of palladium chloride per 1 liter of water.

Abstract: An artificial lens including a lens system having eccentric axes for in an eye having a macula and an enlarged natural pupil is shown. The artificial lens comprises a first optical lens system and a second optical lens system. The principal axis of each optical lens system is eccentric to each other and the distance between each principal axis is selected to enable the first optical lens system and the second optical lens system to be operable within the enlarged pupil. The lens system of the artificial lens system directs light rays from each image of each lens of the first optical lens system and second optical lens system onto a fovea centralis of the macula of an eye. In the preferred embodiment, a prism having a preselected diopter power is positioned on a selected surface of one of the first optical lens system and second optical lens system for directing light rays from an object onto a fovea centralis of the macula of an eye. A contact lens having an eccentric optical system is also shown.

Abstract: A punctum plug for insertion through a punctum opening of an eye and into the canaliculus to occlude the punctum opening and canaliculus is shown. The punctum plug, or implant, comprises an elongated member having a pair of spaced ends wherein one of the pair of ends includes a distal section, preferably in the form of collapsible expanded section which terminates in a distal tip which extends in a direction substantially normal or perpendicular to the central axis. The other end of the pair of ends includes a thin retaining lip which extends in an anterior direction and which is adapted to be oriented to extend beyond the edge of the punctum opening and to engage the lip margin defining the eyelid. The elongated member, including the collapsible expanded section and distal section, are formed of a dimension to pass through a punctum opening of an eye. A method for treating external eye condition due to a deficiency of tears utilizing the punctum plug is also shown.
