Abstract: ABSTRACT OF THE DISCLOSURE         The invention contemplates improved extraocular-lens structures for contact with the cornea of a human eye, to be worn in place of spectacles.  The construction features a lens element of requisite prescription power but of diameter which substantially equals or only slightly exceeds the fully dilated pupil size of the wearer, and fenestrated haptic structure peripherally engaged to the lens.  The haptic structure extends radially outwardly and is so thin and axially compliant as to be self-conforming to the curvature of the cornea and to effectively adhere thereto, thus stabilizing the lens for retention of its position on the optical axis of the eye.  The haptic structure is formed by two sheets of transparent material laminated to opposite sides of the lens and to each other.  The effective surface of the haptic area is reduced by photographically delineated milling to fenestrate the haptic structure radially outwards of the lens.

Abstract: CLUTCH MODULATING SYSTEM ABSTRACT OF THE DISCLOSURE    In an agricultural vehicle in which a power takeoff modulating valve is shifted in response to a control lever so as to pass pressurized hydraulic fluid through a groove in the outer surface thereof between recesses in an adjacent bore wall for application to a power takeoff clutch to cause engagement of the clutch, application of the hydraulic fluid pressure to the clutch is modulated by an arrangement which selectively diverts the pressurized hydraulic fluid away from the clutch and to a sump in accordance with the rate of pressure increase of the hydraulic fluid to prevent excessively rapid engagement of the clutch.  The hydraulic fluid is sumped by a trimmer valve having a first end which immediately responds to high fluid pressures by sliding into a position which sumps the conduit supplying hydraulic fluid to the clutch by an amount directly related to the pressure.  An opposite second end of the trimmer valve also responds to the pressure of the hydraulic fluid but much more slowly because of a restriction in the conduit coupling the second end to the hydraulic fluid supply conduit.  As sufficient hydraulic fluid passes through the restriction so as to equalize the fluid pressure at the opposite ends of the trimmer valve, the trimmer valve is returned to a position in which the sump is cut off and the hydraulic fluid pressure is applied to the power takeoff clutch.

Abstract: ABSTRACT OF THE DISCLOSURE A microwave transmission system for multipath propagation operating according to the angle diversity principle and comprising a transmitting and receiving device including a reflector antenna and a waveguide exciter horn wherein a fundamental mode and modes of a higher order can propagate, a mode coupler following the exciter horn for separating the energy components of the main mode and the higher order modes, and receiving and combining devices for obtaining the best signal from the received energy components of the various modes.  The exciter horn is dimensioned so that at least two independent modes of a higher order or combinations thereof having the same polarization as the main mode can be excited in the waveguide exciter horn in addition to the main mode.  In order to enlarge the radiation gain of the antenna, the waveguide exciter horn is designed, in its basic structure as well as by means of additional structural elements, such as pairs of apertures, corrugated structures, steps and bends, such that the aperture angle (.alpha.) of the radiation lobe of the main mode is matched to the aperture angle (.beta.) of the radiation lobes of the higher modes or vice versa in the plane of the electrical field as well as in the plane of the magnetic field.  The mode coupler feeds more than two mutually independent received signals from the received energy components of the different modes separately to the receiving and combining devices and includes a transmitting port which oxcites one mode whose preferred field direction is orthogonal to the preferred field direction of the received main mode.
