Abstract: A dosing cup for delivery of medicinal fluid includes a base wall, a sidewall, a first gripping portion, and a second gripping portion. The sidewall extends from the base wall to an upper rim, thereby defining a medicinal fluid-receiving volume. The first gripping portion is formed at a first position of the sidewall. The second gripping portion is formed at a second position of the sidewall opposite the first position across the medicinal fluid-receiving volume. Each of the first gripping portion and the second gripping portion include one or more anti-nesting projections that extend from an outer surface of the sidewall a distance beyond an inner diameter of the upper rim.

Abstract: An embryo transfer catheter with a protective sheath is disclosed. The use of a protective sheath shields a guide catheter from cervical mucus. The retracted open flaps of the outer protective sheath draw the mucus and blood away from the inner guide catheter. This allows an inner embryo transfer sheath to enter the uterus unobstructed. The embryo is then transferred to the uterus by means of fluid pressure with a culture medium. The protective sheath may be snap fit onto the guide catheter. The sheaths and catheters may be manufactured in a variety of lengths for individual convenience and then snap-fit onto each other for better control during an embryo implantation procedure. Other catheters and related instruments may also be manufactured with snap-on features.

Abstract: In accordance with the present invention, there is provided an aircraft engine air intake cover for use with an air intake which is characterized by an air velocity profile therewithin. The air intake cover is provided with an air induction plate which disposed across at least a portion of the air intake. The air intake cover is further provided with a multitude of air induction ducts. The induction ducts are disposed about and extend through the air induction plate. Each induction duct has a duct inlet, a duct outlet and a duct body interposed between the duct inlet and the duct outlet. The duct inlets each respectively define an effective inlet diameter. The duct bodies each respectively define a duct body length which is greater than the associated effective duct inlet diameter. The duct outlets each respectively define an effective outlet diameter greater than the effective inlet diameter for increasing the cohesiveness of the air velocity profile within the air intake.

Abstract: A ram wing vehicle comprises a main structure extending between a nose end and a tail end, including an aerodynamic lifting body having an aspect ratio less than approximately 1.0 and extending between a leading edge and a trailing edge. The ratio of the thickness of the lifting body intermediate the leading edge and the trailing edge to the length of the chord thereof is greater than approximately 1:8. A propulsion source is provided adjacent the nose end for generating an efflux and for directing the efflux beyond the tail end in a direction away from the nose end. A directional control mechanism is positioned adjacent the nose end for turning the vehicle about the yaw axis into a curve having a center and so vectoring the efflux from the propulsion source as to direct the efflux to the outside of the turn and the nose end toward the center of the curve.
