Title: Parabola generators with auxiliary reset function
Inventor: FERNSLER RONALD E
IPC: H04N3/233
Filed: 1991-04-04
Granted: 1995-02-07
Abstract: A parabola generator for geometric correction of a television raster, comprises: a resettable circuit for generating a repetitive ramp signal and a resettable integrator for generating a repetitive parabola signal from said repetitive ramp signal. A first resetting circuit initializes the ramp circuit at a frequency related to a scanning frequency. An auxiliary resetting circuit initializes the integrator prior to integrating each repetitive ramp. The auxiliary resetting circuit minimizes timing errors from variations of the ramp signal due to transient conditions. In one embodiment, the scanning period is a horizontal scanning period and the ramp and parabola circuits are reset at the end of each horizontal scanning interval. In this case, the first and auxiliary resetting circuits are responsive to horizontal retrace pulses, for example the leading edges of the horizontal retrace pulses. A further circuit modulates the periodically reset parabolic signal at a vertical scanning rate. In another embodiment, the scanning period is a vertical scanning period and the ramp and parabola circuits are reset at the end of each vertical scanning interval. In this case, the first and auxiliary resetting circuits are responsive to vertical retrace pulses, for example the leading edges of the vertical retrace pulses. A further circuit modulates the periodically reset parabolic signal at a horizontal scanning rate. The parabolic waveform is also reset responsive to a timing signal, rather than by allowing the minimum level of the waveform to be defined only by uncontrolled operation of an integrator.

Title: Light weight, fast steering riding trowel
Inventor: ALLEN J DEWAYNE
IPC: E04F21/24
Filed: 1991-04-05
Granted: 2005-12-20
Abstract: A compact, lightweight riding trowel for finishing concrete of enhanced maneuverability. A rigid frame is supported above the concrete by a pair of downwardly projecting synchronized rotors, each of which revolves multiple blades frictionally contacting the surface. Lights attached to frame corners provide illumination. The operator manually steers with a pair of primary control levers which tilt the rotors to generate steering forces. The pitch of each rotor blade are controlled manually or electrically, and a cable-driven clutch fork system is activated to vary pitch between minimum and maximum. Each of the tiltable rotor assemblies are driven by gear boxes coupled to the motor through a flexible disk drive shaft. Each gear box is mounted to the frame underside by a pivot steering box.      Parallel lever arms extending beneath the frame in a direction generally perpendicular to the biaxial plane defined by the rotors are deflected by the primary control levers. Each activates elongated torque rods coupled to the gearboxes and tilt the rotors in a plane parallel with the biaxial plane. The torque rods are generally aligned, and for leverage they are braced by a gusset and offset from that axis of rotation defined within the pivot boxes which enables one of the rotors to tilt in an and perpendicular to the biaxial plane. One lever arm controls a torque shaft interconnected with a tertiary linkage system which tilts one rotor in a plane perpendicular to the biaxial plane, and which achieves a mechanical advantage.

Filed: 1990-09-27
Granted: 1995-04-18
Abstract: An apparatus for manufacturing fiber preforms is described, in which a relatively small motor (36) is able to power a large fan (34) because the fan is kept in a partial vacum condition. A duct (30) connects a fan housing to a vacuum box (24) which has an air flow opening (26) therein of relatively narrow width. A shuttle member (28) is horizontally translatable above the vacuum box (24) on a support bed and the shuttle member is divided into air flow chambers by baffle plates (44). Only a smaller number of air flow chambers can pass above the air flow opening at a single time and this serves to keep low pressure in the vacuum box. In addition, a vortex gate (75) is provided in the duct between the fan housing and the vacuum box and serves to restrict air flow through the duct when the pressure within the duct drops below a certain level.
