Title: Valve gear for IC engine - has spherical valves mounted in split housings in inlet and exhaust ports
IPC: F02B53/04
Filed: 1984-08-28
Abstract: The rotary charge and exhaust flow control valve gear has housings each with a spherical cavity in which is a spherical valve, mounted in the intake and exhaust ports. The housings can be split to define portions of the cavity, aiding access to the valve ball. - The ball rotates in each housing to control a flow orifice. The sides of the housing sections can have a slight taper to allow a male-female connection when assembled by a press. The valve balls have orifices matching those in the housing.(0/0)

Abstract: ABERRATION CORRECTING SUBREFLECTORS   FOR TOROIDAL REFLECTOR ANTENNAS                 ABSTRACT OF THE DISCLOSURE The correction of aberration in toroidal reflector antennas by a novel type of subreflector is disclosed.  The specific shape of the subreflector ultimately depends on the geometry of the toroidal reflector.  However, in any case, the effect of the subreflector is to achieve a point focus in a system which, without the subreflector, does not focus at a point.  Considering the antenna system from a radiation point of view, this is equivalent to turning a non-planar equiphase surface in the aperture into a plane thereby eliminating the phase error about the aperture plane perpendicular to the desired direction of propagation.  This is achieved while preserving the wide field of view characteristic of the torus antenna by designing the subreflector so that all pathlengths from a reference plane are constant and equal to a desired reference pathlength.          In a practical case, the design of the subreflector is accomplished by developing a heuristic geometric optics model of the focusing properties of the toroidal reflector and using a programmable general purpose digital computer to generate the subreflector shape by numerically computing points on the surface of the subreflector for separate, individual rays intercepted by the toroidal reflector, for a bundle of rays incident from the desired direction.  These points may then be used to machine the subreflector surface using well-known numerically controlled milling machines.          Of special significance is an optimum antenna configuration using what may be termed a "Cassegorian" subreflector designed according to the principles of the invention having similarities to both Cassegorian and Gregorian subreflectors.

Abstract: Abstract of the Disclosure A frequency mixer-downconverter which can be tuned as either a single sideband mixer or a double sideband mixer and which has a wide tunable RF band-width and low conversion loss is disclosed.  A high-frequency input signal is coupled from an input wave-guide to a shielded suspended stripline.  Two Schottky barrier diodes are connected proximate to the waveguide-to-stripline transition, between the inner conductor and the outer conducting channel of the stripline. The two diodes intermodulate the input signal with a subharmonic pumping signal which is also coupled to the suspended stripline from a waveguide input.  An intermediate frequency signal, at a frequency equal to the difference between the input signal and twice the frequency of the pumping signal, is generated as an intermodulation product and transmitted on the suspended stripline to an output. The downconverter can be tuned as either a single sideband mixer or a double sideband mixer by positioning an E-plane wave-guide tuning short and an H-plane waveguide tuning short at the transition between the input waveguide and the suspended stripline,.  For a single sideband mixer the tuning shorts are adjusted to provide at the input wave-guide-to-stripline transition a reactive termination at the image frequency and an impedance match at the input signal frequency.  The tuning shorts are positioned to provide the same impedance match at both the image frequency and input signal frequency for double side-bad tuning.
