Historical Examples of paraboloid
In this case, therefore, we shall obtain three paraboloid boundary curves, as shown in Fig. 93.The Phase Rule and Its Applications
Behind this was a curious, paraboloid projector made up of hundreds of tiny, carefully orientated coils.The Ultimate Weapon

Also, the form of cambered surface should be a paraboloid—not arc or arc of circles.The Theory and Practice of Model Aeroplaning
V. E. Johnson
If it lies at the infinity, the plane at infinity is a tangent plane, and the surface is called a paraboloid.
The Silky Epeira also has all the elbow-room she needs; and her paraboloid is not without elegance.The Life of the Spider

- a geometric surface whose sections parallel to two coordinate planes are parabolic and whose sections parallel to the third plane are either elliptical or hyperbolic. Equations x ²/ a ² ± y ²/ b ² = 2 cz
- A surface having parabolic sections parallel to a single coordinate axis and elliptic sections perpendicular to that axis.
