Title: Improvements in multi-magazine arrangements for typographical composing machines
IPC: B41B11/06
Filed: 1926-07-19
Abstract: 262,670. Intertype Corporation. June 10, 1926, [Convention date]. Magazines for type-bar-making machines.-In machines of the kind described in Specification 14582/90, which are provided with superposed magazines and shift-mechanism therefor, the means for moving different magazines into operative position is controlled by mechanism for lifting and lowering the matrix-delivery ends of the magazines relatively to the escapement-actuating devices. The magazine frames 11, Fig. 1, are connected by side-plates 11<a>, so as to form a unit, which is supported by side-brackets 12, secured to the machine frame bv trunnions 21 and bolts 24. In the magazine unit is mounted a shaft 30 carrying rollers 31, which travel on inclined rails 33 on the brackets 12. The magazine-shifting mechanism comprises a shaft 43, Fig. 5, which supports the magazine unit at its lower end, and is carried by cranks 44 from short shafts 41, which project through slots 34 in the brackets 12. The shafts 41 can be rotated by means of a handle 47, and carry pinions 40 which gear with racks 36 extending along the slots 34. Eccentrics 48 on the shafts 41 occupy bearings in the lower ends of links 32, which are connected to the shaft 30. Upon rotation of the handle 47, the eccentrically-mounted shaft 43 moves in an approximately cycloidal path, so as to lift the lower ends of the magazines away from the escapementreeds. The eccentrics 48 cause a varying movement of the rollers 30 along the rails 33, which occurs mainly between the lifting and lowering movements. The danger of collision between the magazines and the escapement-reeds is thereby avoided, and the load is more evenly distributed over the shifting operation. The eccentric-mechanism also provides a locking- means to prevent accidental movement of a magazine from operative position. Registration of a magazine is ensured by the engagement of lugs 57 on the magazine unit with recesses 58 in the brackets 12. The magazine unit can be tilted rearwardly, to permit removal of the magazines, by means of a handle 14. A latch 19 is adapted to engage a flange on the machine frame, in order to hold the magazines in tilted position. The rails 33 and slots 34 may be formed on separate members cast integrally with the machine frame.

Title: Improvements in or relating to the control of the output wavelength of an optical maser or laser
Inventor: COOK ALAN HUGH
IPC: H01S3/139
Filed: 1963-05-07
Abstract: 1,082,961. Automatic frequency control system. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 7, 1964 [May 7, 1963; Sept. 2, 1963], Nos. 18066/63 and 34651/63. Heading H3A. [Also in Divisions G1 and H1] In order to stabilize the wavelength of the output of a C.W. gas laser the optical path length of the resonant cavity of the laser is cyclically varied so as to result in a variation in output radiation intensity and a signal derived from the variations is used to control the optical path length of the cavity in such a manner that the intensity of radiation is shifted towards a point of minimum rate of change of intensity with respect to wavelength on the intensity/wavelength characteristic of the laser. As shown in Fig. 5 and Fig. 1 (not shown), a signal derived from the radiation passing through mirror 24 of the cavity of the gas laser falling on photo-diode or photomultiplier 26 is fed via servo-amplifier 27 to electromagnetic device 29 mounted on the mirror support 20, the device 29, Fig. 4 (not shown), causing a small variation in the separation of mirrors 24, 25 depending upon the amplitude of the D.C. signal from amplifier 27. The D.C. signal has in addition an A.C. superimposed on it so that the optical path length of the cavity is cyclically varied resulting in a cyclic variation of wavelength X, Figs. 2, 3, of the output radiation and a variation in the intensity. The signal derived from the intensity of the radiation is applied to device 29 in such a manner as to change the length of the resonant cavity to produce a radiation of wavelength displaced towards a point on the intensity wavelength characteristic curves where the rate of change of intensity with wavelength is a minimum, i.e. points B, Fig. 2 being the curve for a single isotope and Fig. 3 for a plurality of isotopes. Since the variation in intensity at these points is small the detected variation in intensity will also be small and the wavelength is stabilized at this point. The excitation of the laser by oscillator 16 is also stabilized through a second photo-electric device 36 and servo amplifier 37. The cyclic vibration may be applied to one mirror and the correcting force to the other. In order to overcome the frequency modulation of the output beam produced by the cyclic vibration the mirror vibration is suppressed at predetermined intervals for short periods. Alternatively, a second C.W. laser 41 may be employed, Fig. 5, and a beat frequency signal derived from the two lasers is used to adjust the optical path length of the second laser's cavity to reduce the beat frequency and so make the optical frequency of the second laser the same as the mean optical frequency of the first laser.
