They also still retain vestigial anterior and posterior " auricles " ( " ears ", triangular shell flaps ) along the hinge line.
22.
To get an end view of SU, projection 4 is drawn with hinge line H 3, 4 perpendicular to S 3 U 3.
23.
The initial tail configuration was unusual, the rudder hinge line being vertical when the aircraft was on the ground rather than when in flight.
24.
Rignot calculates that the hinge line retreated by three-fourths of a mile a year from 1992 to 1996, the period for which data are available.
25.
The loss of the hinge line was an important evolutionary innovation, "'rhynchonellids "'being the first truly non-strophic shells with a purely internal articulation ( teeth-sockets ).
26.
Along the hinge line of the shell are, in most cases, a number of hinge teeth which prevent the valves from moving laterally relative to one another.
27.
The all-moving tailplane was rectangular, the fin triangular with a vertical hinge line for the quadrilateral rudder which sloped upwards on its lower edge to provide tailplane clearance.
28.
Manufactured from the hinge line of a giant clam ( Tridacna gigas ), the shell adze was found associated with a Neolithic burial assemblage in Duyong Cave, Quezon, Palawan.
29.
The fin, set forward so the rudder trailing edge is above the elevator hinge line, is shaped like a shark's back fin, strongly swept and with a curved leading edge.
30.
It was rectangular in plan, with a aspect ratio ailerons occupied all the trailing edge of the outer panels, aerodynamically balanced by small auxiliary surfaces mounted forward and well above the hinge line.
