IN NATURE (vol. xx. p. 103) there appears an abstract of a paper by Prof. E. W. Blake on a machine for drawing compound harmonic curves. Prof. Blake is doubtless not aware that this machine is based ...

Compound freeform surfaces are widely used in bionic and optical applications. The manufacturing and measurement of such surfaces are challenging due to the complex geometry with multi-scale features ...

A high-viscosity, rigid compound, Tra-Bond 216R01 has a lap shear of 3,600 psi with a room-temperature cure and 4,500 psi with a 65°C heat cure. A high-viscosity, rigid compound, Tra-Bond 216R01 has a ...
