Abstract: 185,538. Higgin, J. J. Holmes-, and Higgin, F. B. Holmes-. June 17, 1921. Magazine hand cameras with connected action between shutter and changing mechanism.- Relates to cameras of the kind in which the shutter lever is prevented after the exposure from returning to its normal position by a catch which is released on operating the film-winding mechanism, and consists in releasing the catch by means, such as links and levers or a Bowden wire, actuated by the external winding-handle of the film spool. In the form shown, a spring- pressed rod 1 slides vertically in guides on the lens-board A, and is bent at its upper end, where it passes through a longitudinal slot in a fixed plate 5, and is hooked at 2 so as to press lightly against the back of the shutter trigger 3. When the trigger is depressed to make the exposure. the hook 2 springs forward over its top, preventing its complete return. When the film winding- handle 27 is turned, the boss 2E thereon displaces a sliding rod 26, which transmits the movement through a system of levers and rods 23, 22, 20, 17, 8, to a pivoted platform 13 upon which rests the base of the rod 1; this platform is upwardly displaced, and lifts the rod 1 so as to cause a bevelled lug 6 thereon to wipe against the front end of the slot in the plate 5, thereby retracting the hook 2, and freeing the trigger 3. The system of levers and rods may be replaced by a Bowden wire.

Title: Liquid crystalline light modulation
IPC: G02F1/137
Filed: 1975-04-25
Abstract: 1512393 Controlling light XEROX CORP 25 April 1975 [29 April 1974] 17244/75 Heading G2F When an optically absorbing material is in contact with an optically negative (cholesteric) mesophase in which it is insoluble, the absorption bands become circularly dichroic, and factors such as heat, shear, pressure, electric and magnetic fields, foreign chemicals, which affect the pitch, and the position of the reflection band, of the mesophase, while controlling the magnitude of the circular dichroic absorption, do not affect the spectral position thereof. The claims relate generally to directing light at the absorbing material when in contact with the mesophase and applying a stimulus to the mesophase to change the light reflection band whereby the absorption of circularly polarized light by the material is modulated. The incident light may be linearly polarized and the absorption band may be outside the reflection band. The sign and amplitude of circular dichroism CD are functions of wavelength, but at any one wavelength the sign is determined solely by the band of the helical structure of the mesophase, and its amplitude is a function of the helical pitch. The CD bands may be displaced relative to the normal absorption bands. The absorbing material may be dispersed in the mesophase or form an adjacent layer. The ratio of CD to optical density increases as the size of the dispersed particles decreases. Above a threshold level, electric or magnetic fields convert the mesophase to an optically positive state and destroy the CD. The incident light itself may comprise infrared radiation which produces heating of the mesophase and a variation in the CD.

Title: Process for producing caustic soda low in sodium chloride
IPC: C01D1/30
Filed: 1931-06-15
Abstract: In a process for the production of caustic soda with a low sodium chloride content, a 50 per cent solution of caustic soda obtained by concentration is cooled to about 18-20 DEG  C. and freed from solid sodium chloride, whereupon the remaining solution is cooled to a temperature not exceeding about 10 DEG  C., crystals of hydrated sodium hydroxide separating out, while the sodium chloride remains dissolved in the supersaturated solution.  After the separation of the hydrated sodium hydroxide crystals, the mother liquor is mixed with fresh 50 per cent caustic soda solution and after the separation of further solid sodium chloride, the process is repeated.  The cooling should preferably be slow and may take place in a tubular cooler containing a worm conveyer.  The cooling may however be carried out discontinuously in separate stages for example 20-17 DEG C. in a first stage, 17-14 DEG  C. in a second and 14-10 DEG  C. in a third, separating the solid hydrate formed at each stage.  Preferably only up to one-half of the caustic soda content of the liquor is separated as solid hydrate.
