    Abstract: There is disclosed a light modulating structure including an open-ended housing within which an electromagnetically driven tuning fork structure is supported. A source of light is located between the tines of the tuning fork. Apertured shutter members are secured to the ends of said tines intermediate the light source and the open end of said housing, relative movement of the shutter members causing variations in light intensity emitted by the light modulating structure. The tuning fork is of composite construction and is manufactured by a method which involves shaping at least two tuning fork tines to a desired thickness in a single machining operation before the two tines are separated and joined together symmetrically to form a composite tuning fork.

    Abstract: A light modulator structure employs a cross compound tine tuning fork structure arranged to produce the effect that the ends of the tines have exaggerated rotational motion with respect to each other and this motion is exploited by mirrors secured to the ends of tines to scan over a relatively wide angle a light beam projected to reflect successively from the two mirrors. A similar compound structure is incorporated in a simple scale having no frictionally moving parts. The scale compound cantilever is parallel rather than crossed and substantially eliminates scale pan rotation.

    Abstract: There is disclosed a tuning fork resonator with electrical drive and pickup coils and a tuning fork having a pair of tines, a common tine-junction section, a supporting portion for securing the fork in place and a pliant section between the common tinejunction portion and the supporting portion of the fork. The fork is provided with a counterbalance which is oppositely disposed from the tines of the fork with respect to the pliant section. The counterbalance counteracts the tendency of the tine ends to rotate in response to lateral acceleration force due to compliance of the pliant section and in some cases also counteracts the response to lateral acceleration force due to bending of the tines themselves. A version is disclosed in which there are two forks laterally spaced with the tine ends physically bridged together by shutters to form an elongated undulating aperture and with the counterbalance and common tinejunction portions of the two forks consisting of a common bridging structure which is relatively rigid so that the two pairs of tines of the respective fork sections are substantially in unison both as to tine vibrations and as to reaction to acceleration forces.
