Abstract:
An energy modifier machine is disclosed. The machine is a series of orbiting disc assemblies (4) connected to the drive motor (8) by propeller shafts (5) and universal joints or constant velocity joints (6), and connected to the output shaft by crankshafts (3). The input shafts and output shaft are separated by low friction bearings. The machine harnesses the centrifugal force created by rotating the centrifugal arms and mass within the orbiting disc assemblies, which is modified into a simple rotary motion by the crankshafts. The rotary energy can be taken off from an extension (10) of one or more of the crankshafts. The machine will provide a net positive outcome when comparing the energy required to produce the centrifugal force, to the rotary energy resulting from harnessing the centrifugal energy.
Abstract:
Apparatus for simultaneously rotating a plurality of parallel shafts (12) connected, for example, to an array of rf switches (not shown) that feed energy to or from an array of antenna feed horns. Each shaft (12) is connected by a separate crank (34) to a planar drive plate (16) that is controllably moved relative to the switches in an orbiting fashion, to rotate the shafts (12) in unison. The drive plate (16) is controllably moved by a motor drive system that includes an orbiting motor (20) secured to the plate (16) and a base motor (22) secured to a fixed substrate (14) that houses the switches. The output shafts (68 & 70) of the two motors are coupled together such that operation of either motor moves the orbiting motor (20), and thus the drive plate (16), in an orbiting motion about the base motor (22) and substrate (14).
Abstract:
The simultaneous actuating mechanism (10) for parallel axis rotors includes a housing (20) and a plurality of rotating rotors (30) mounted in spaced relation inside the housing (20), the rotors (30) having parallel axes of rotation. A crank pin (32) extends from each rotor (30) at a position offset from the corresponding axis of rotation. A driving assembly (40) is coupled to the crank pin (32) of all the rotors (30). Operation of the driving assembly (40) causes simultaneous rotation of the rotors (30) to facilitate various mechanical functions, such as threading, steering, and reciprocation of multiple elements.
Abstract:
Polarization preserving front projection screens and diffusers provide optimum polarization preservation for stereoscopic 3D viewing, as well as improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed screens direct light from a projector toward viewers within a diffusion locus, while maintaining optimum gain characteristics. More specifically, light incident on a region of the front projection screen from a predetermined projection direction is reflected by an engineered surface to a predetermined diffusion locus after undergoing substantially single reflections. The engineered surface, comprised of generating kernels, is used to optimally diffuse illumination light into a range of viewing angles, within the diffusion locus, with suitable gain profile, while optimally preserving polarization for 3D applications. Such a screen, when combined with matched polarization analyzing eyewear, provides extremely low cross-talk from any observation point.
Abstract:
A gearless transmission which uses one or more rectilinear drive mechanisms in series. The rectilinear drive mechanism comprises paired eccentric discs (31, 32), mounted on a crankpin (22) and guided by two pairs of rails (26, 27, 36, 37) orthogonal to each other, such that the discs rotate in the opposite direction to the crank. The two pairs of rails are mounted on fixing plate (38). In the transmission, the fixing plate is allowed to rotate, in some modes of operation, which provides a 2:1 speed ratio. The reverse rotating orbital motion of the paired discs is converted to reverse rotation, concentric with the input shaft, by means of a multicrank coupling (45, 46). Clutches (not shown) are used to select reverse rotation, direct drive or variable ratio outputs. Embodiments of the same mechanism provide reciprocating motion along at least one axis and also along two orthogonal axes so that the invention can be used as a piston machine with built-in reverse motion shafts which may be selectable.
