Title: Improvements in or relating to spectrographic apparatus
IPC: G01J3/14
Filed: 1957-07-16
Abstract: 850,474. Spectrographs. LEITZ G.m.b.H., E. July 16, 1957 [July 26, 1956], No. 22490/57. Class 97(1) Spectrographic apparatus for examining an object which has stronger absorption in the invisible spectral range than the visible range comprises a microscope permeable to visible and invisible light for creating an image of the object at the entrance slit of a spectrograph so that a spectrum may be recorded in invisible light and a phase-contrast microscope for focussing said image in visible light. As shown, radiation from a source 1 passes through a microscope permeable to visible and invisible light and comprising an annular diaphragm 3 which is imaged by lens 4 in the entrance pupil of mirror condenser 5, and mirror objective 7 forms an enlarged image of an object 6 in the entrance slit 8 of a spectrograph made'up of lenses 9, 11, prism 10 and photographic plate 12. Behind slit 8 are a lens 13 and a prism 14 which is impermeable to invisible light and can be moved out of the light path to lens 9. When prism 14 is in position shown and the object 6 is illuminated by visible light, lens 13 images the exit pupil of objective 7 in the entrance pupil of the condenser 15 of a phase-contrast microscope, including objective 16, phase plate 17 and eyepiece 18, and object 6 is imaged in the plane 19. By means of this microscope object 6 can therefore be focused on the slit 8. The prism 14 may thereafter be moved out of the light path to lens 9 and the spectrum photographed in invisible light. Instead of prism 14, a fixed semi-transparent mirror may be used. A rotatable stepped diaphragm or wedge 20 is disposed in front of slit 8 to produce intensity graduations across plate 12.

Abstract: 664,407. Television. RADIO CORPORATION OF AMERICA. Aug. 30, 1948 [Sept. 27, 1947], No. 22813/48. Class 40 (iii). [Also in Group XXXV] The frequency of an oscillator which produces a scanning saw-tooth wave (for use in a television receiver) is controlled by means of a control voltage which is derived by combining a non-sinusoidal wave of recurring peaks related to the produced scanning wave with received synchronizing signals. In the arrangement shown in Fig. 1, the voltage wave 46 which is produced in the output circuit of the line scanning amplifier 35 fed from a blocking oscillator 38 is integrated in the network 28-31 and fed to a cathode-follower stage 53 together with line synchronizing pulses 25 after differentiation in the network 26-27, the output from the amplifier 53 being the desired control voltage. This output provides, firstly, a direct current voltage which is developed across condenser 74 and applied to the grid of oscillator 38 and, secondly, a source of synchronizing pulses which are developed across resistor 78 and applied to oscillator 38 via transformer 64 and condenser 66, the first output from amplifier 53 serving to maintain the free running frequency of the oscillator very close to the frequency of the synchronizing signals and the second output serving to trigger the oscillator at the desired rate. The nature of the control signals developed by valve 53 for various phase relationships of scanning wave and synchronizing signals is described with reference to Figs. 2 to 7 (not shown).
