Title: Method and apparatus for blocking lenses during grinding and polishing operations
IPC: B24B13/005
Filed: 1980-10-03
Abstract: A method for the production of spectacle lenses from a lens blank, the method comprising the steps of cutting a detent or nick in the lens blank D at a defined location on the periphery and thereafter effecting subsequent grinding, lapping and polishing operations in apparatus incorporating a lens holder A with a projecting means C at a defined angular position which cooperates with the detent in the lens, the lens blank being removable from the lens holder in one apparatus during processing and subsequently replaced in the holder of the same or another apparatus for further processing, the projection and detent providing correct relative angular alignment in other lens holders during all processing operations. The method does not require conventional "blocking" and avoids transfer of the lens and holder from one work station to another. <IMAGE>

Title: A radar apparatus
Inventor: FRANKLIN DONALD PETER
IPC: G01S13/34
Filed: 1981-05-14
Abstract: A radar apparatus transmits a pulsed signal a portion of which is fed to a mixer 5 to overlap with the corresponding return pulse. The output of the mixer is a modified pulse of duration equal to the common interval of occurrence of the pulses, The spectrum of the modified pulse is related to that duration. A circuit 7 mixes the modified pulse with two square waves of different frequencies which are harmonics of the p.r.f. of the transmitted pulses. The amplitude of either output of the circuit 7 represents range. In a preferred embodiment the ratio circuit 80 determines the ratio of the amplitudes of a Doppler modulation frequency of the outputs of the circuit 7. This modulation is selected by a Doppler selection circuit 90. In order to simultaneously detect several targets having different Doppler frequencies, a plurality of differently tuned Doppler selection circuits and a plurality of ratio circuits may be used. The radar may have many range channels each as described above, by providing different delays to the portion of the transmitted pulse fed to a plurality of mixers 5.
