Abstract

737,794. Optical-projection apparatus. REASON, R. E., ADAMS, J. R., and KAPELLA, Ltd. Aug. 26, 1953 [Sept. 5, 1952], No. 22382/52. Class 97 (1). [Also in Group XIX] In the apparatus shown, the blade B has previously been marked with two section profiles B3 and B4 between which is disposed a partially transparent reflector H forming an image of the profile B<SP>4</SP> in the plane of the profile B<SP>3</SP>. Two lamp filaments J and J<SP>1</SP> are imaged respectively by pairs of curved mirrors J2, J3, J<SP>4</SP> and J<SP>5</SP> on two opposite faces of the blade B in the planes in which the section profiles B3 and B<SP>4</SP> are marked. An objective H<SP>2</SP> focuses the section profiles B<SP>3</SP>, B<SP>4</SP> on to an image plane H<SP>1</SP>. Specifications 727,899 and 728,588 are referred to.
