Granted: 1980-09-02
Abstract: Title:          Magnifier.     Abstract of the disclosure:            A magnifier having a relative aperture exceeding f/1, an angle of view wider than 2 x 25°, and a pupil distance longer than 0.9 f, in particular for viewing the anode screen of an image intensifier tube forming part, for example, of a viewing device mounted on a vehicle.            As viewed in the direction of the observer, the magnifier comprises, in succession, a) a first component consisting of a positive lens; b) a second component consisting of a positive power lens; c) a third component consisting of a meniscus-shaped lens concave to the observer and comprising two lens components cemented together; d) a fourth component consisting of a positive power lens; the sum of the powers of the two refractive surfaces of the second component having a value of between 0.15/f and 0.55/f, the power of the refractive surface of the third component facing the observer having a value of between 0.63/f and 1.03/f, and the sum of the powers of the two refractive surfaces of the fourth component ranging from 0.45/f to 0.65/f.   The magnifier has a large pupil distance, so that the scene on which the viewer is focussed can be properly observed even when the vehicle moves in a bumpy terrain, and yet has a back focal length long enough to allow the use of a plane parallel-sided plate on the anode screen of the image intensifier tube in a thickness sufficient to diminish light diffraction effects and internal reflections therein.

Granted: 1979-02-20
Abstract: ABSTRACT OF THE DISCLOSURE        A bed carrying frame comprising a pair of generally parallel side rail members, of hollow rectangular shape, a pair of end rail units, each of which consists of two relatively telescoped end rail members which are also of hollow rectangular shape, and corner bracket members mounting each of the end rail members on one of the side rail members.  The corner bracket members are substantially identical and function to pivotally mount the end rail members on the side rail members for movement between folded positions in which two end rail members are folded against each side rail member and assembled positions in which pairs of end rail members are relatively telescoped and cooperate with the side rail members to form a rectangular frame.  A novel latch unit is provided for each pair of relatively telescoped end rail members to maintain the end rail members in predetermined relative positions.

Abstract: ABSTRACT OF THE DISCLOSURE Separation or enrichment of isotopes from a mixture of compounds containing the isotopes, by subjecting a vaporous mixture of the compounds containing the isotopes to electromagnetic radiation, e.g. laser radiation, to non-selectively excite the molecules with only one compound exceeding the energy threshold required for separation of the compounds.  To effect this, the frequency of the radiation must be chosen so that in the spectrum of the mixture of isotope compounds to which the radiation is applied, the compounds are at different energy levels and upon application of the radiation only one compound exceeds the energy threshold level required for separation of the isotope compounds.

Title: Responsive variable quench time delay for quench strobe
Inventor: POPE WILLIAM R
IPC: G03B15/05
Filed: 1977-03-31
Granted: 1980-08-19
Abstract: ABSTRACT OF THE DISCLOSURE A photographic camera apparatus is provided with an automatic illumination and exposure control system for controlling a pair of scanning type shutter blade elements as well as a flash fire and quench signal directed to a quench strobe operatively associated therewith. The camera apparatus may be operated in either a "fill-in" flash mode of operation or an ordinary flash mode.  During the "fill-in" flash mode of operation, the time delay in quenching the strobe is progressively decreased as a function of increasing ambient scene light intensity so that the shutter blade elements admit progressively less reflected strobe light from the subject during the finite time required for the shutter blade elements to close.

Abstract: ABSTRACT OF THE DISCLOSURE      The disclosed Power Shift Mechanism is adapted to later-ally shift an earth working implement, such as a vertical plow, relative to a tractor or the like.  In the disclosed embodiment, the plow is mounted on a slide bracket and the bracket is slide-ably mounted on a support frame.  The shift mechanism includes a fluid operated piston-cylinder connected between the frame and a pivot link pivotally connected to the slide bracket.  The pivot link may be rotated by the piston-cylinder to either of two posi-tions and locked in place by releasable connectors.  The piston-cylinder will then rotatably shift the pivot link or laterally shift the bracket and the earth working implement.  The shift mechanism thus increases the effective stroke of the piston-cylinder and reduces the power requirements of the shift mechanism.
