Abstract: The present invention relates to pre-ignition lubrication mechanisms for internal combustion engines, and more particularly to a pressurized pre-combustion oiling mechanism for use with internal combustion engines. The present invention provides an accumulator tank containing either air or an easily condensible gas. The pressurized oil causes the air or gas in the bag to become compressed, causing a decrease in occupied volume in proportion to the pressure induced by the oil to allow the oil to occupy a suitable portion of the tank. In the preferred embodiment of the invention, the pressurized oil would cause the condensible gas to undergo a phase change and liquify. Conventional valving known in the state of the art is provided to allow the accumulated pressurized oil to be used prior to a subsequent engine startup, and conventional electronic control systems are provided to engage and disengage the aforementioned valves for a proper pre-ignition lubrication sequence.

Abstract: In general, the invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least one reflector with a smooth concave surface which reflects the energy emitted from the transducing element. The device also has at least two transducing elements for producing this energy. The shape of this reflector surface is preferably defined by either an ellipse or a parabola that is rotated about an axis of revolution, for any angular distance between zero and one complete revolution. The shape of this reflector surface can also be preferably defined by the coincident surfaces of revolution of an ellipse and a parabola that are rotated about a common axis of revolution.

Abstract: The invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least one movable transducing element for producing this energy, and at least one reflector with a smooth concave surface which reflects the energy emitted from the transducing element. The shape of the reflector surface is preferably defined by either a rotated ellipse or a rotated parabola. A reflector surface of either shape is characterized by a continuum of distinct focal points that define a focal curve, such that each distinct focal point of the continuum is a unique focal point of each ellipse or parabola in the continuum forming the reflector surface. The radius of curvature of the parabolic surface of revolution can be extended up to an infinite length, causing the focal curve to appear as a straight line.

Abstract: In general, the invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least two transducing elements for producing this energy, and at least one reflector which reflects the energy emitted from the transducing elements. The shape of the reflector surface is defined by both an ellipse and a parabola that are rotated coincidentally about a common axis of revolution (hereinafter referred to as a "para-elliptic" reflector surface), formed by coincidentally rotating, for up to one complete revolution, a section of both geometric shapes about an common axis of revolution that lies in the plane of both geometric shapes. The resulting "para-elliptic" reflector surface will be characterized by two sets of distinct focal points defining two focal curves. Focused energy will be redirected as if emanating from each focal region, causing each focal region to appear as a virtual source of the energy.

Abstract: A lens incorporates two reflective shells. One shell's surface is generated when a parabola is rotated around a line which lies in the parabolic plane perpendicular to its axis of symmetry. The other shell's surface is generated when an ellipse is rotated about a line lying in the elliptic plane and passing through one focal point at a finite angle to its major axis. The parabolically-generated shell has a characteristic focal curve while the elliptically-generated shell has both a characteristic focal curve and a focal point. The lens incorporates these shells which are aligned so that they have coincident focal curves and axes of rotation. Plane wave radiation travelling parallel to the axis of rotation of the lens will be focused at the focal point of the elliptically-generated shell. Conversely, a transducer placed about this common focal point and can produce radiation which will be converted into a plane wave radiation.

Abstract: An enclosure for a transduction element incorporates a geometrically shaped acoustically reflective shell. This acoustically reflective shell is shaped so that the inner surface thereof is at a least a section of that shape generated when a parabolic structure is rotated around a line which, lies in the plane of the parabolic structure, is perpendicular to the major axis of the parabolic structure. Such geomtrically generated shapes will have one distinct focal curve. A transduction element placed about this focal curve will, in operation, cause acoustic radiation to be produced which will be characterized by a plane wavefront of coherent radiation. Said device may alternately act as a transducer which produces a 360 degree beam width by placement of a plane wavefront producing transduction means at a position above the acoustically reflective shell and parallel to the plane of the distinct focal curve.

Abstract: An enclosure for a transduction element incorporates a geometrically shaped acoustically reflective shell. This acoustically reflective shell is shaped so that the inner surface thereof is at a least a section of that shape generated when an ellipse is rotated around a line which, lies in the plane of the ellipse, is oriented at any angle to the major axis of the ellipse, and contains one focus of the ellipse, or that shape generated when a continuum of ellipses having identical major axes are placed about a line which, lies in the plane of all the ellipses, is oriented at any angle with respect to the major axes of the ellipses, and contains a focal point common to all the ellipses. Such geometrically generated shapes will have one common focus and one distinct focal line.

Abstract: An enclosure for transducers incorporates an interior acoustically reflective shell. This acoustically reflective shell is shaped so that the inner surface thereof is the envelope of at least a section of a cylinder of elliptical cross section, an ellipsoid of revolution, or the envelope of a multitude of said shapes oriented so that the elliptical shapes share one common focus and each has one distinct focus. In this last case, transducers are placed at the distinct foci so that sound produced by them is directed substantially toward that portion of the elliptical acoustically reflective shell to which the distinct foci belong. In operation sound generated by the transducers, operating in phase with one another, is focused and concentrated at the common focus such that this common focus acts as a singular source of phase coherent sound of any desired angular beamwidth and intensity.
