Title: Tetrahedral multi-satellite continuous-coverage constellation
Inventor: DRAIM JOHN E
IPC: B64G1/00
Filed: 1986-07-17
Granted: 1989-06-29
Abstract: An improved, optimized, four-satellite tetrahedral constellation (S₁ to S₄) using common period elliptic orbits is disclosed which provides continuous global coverage (i.e., any point on the earth can always maintain line-of-sight visibility with at least one of the four satellites). The constellation consists of two satellites having perigees in one hemisphere, and two satellites having perigees in the other hemisphere. All satellites have a common period, and positive visibility angles can be maintained down to a constellation (or satellite) period of 27 hours. At higher altitudes (longer periods) both the minimum visibility angles and the mean visibility angles will tend to increase. Replication may be provided by overlaying arrays with convenient offset. The invention is aplicable to any celestial body wherein two satellites have two periapses in one hemisphere and the other two satellites have periapses in the other hemisphere.

Abstract: Orthogonal output signals generated by a stylus (40), are normalized such that they are insensitive to the rotational position of the stylus (40) with respect to the writer's grip. Pressure measurements made by strain gauges (52) on a flexible diaphragm (50) in the stylus (40) are sampled at discrete intervals and a normalization angle of writing movement is calculated, representative of the average direction of the signature, by a processor (60). Each sample of orthogonal output signals is then assigned a vector length which is rotated by the normalization angle. The normalized samples are utilized to perform signature analysis by a comparison with a stored reference signature set of normalized orthoganal samples carried out by the processor (60).

Abstract: A transfer conveyor for transporting an object from an intake location to an output location according to the invention has a frame adjacent the locations, a planet carrier rotatable on the frame about a carrier axis, a wheel rotatable on the frame adjacent the carrier about the carrier axis, and at least one planet gear carried on the carrier and rotatable thereon about a planet axis parallel to but offset from the carrier axis. A ring gear meshing with the planet gear is centered on but not rotatable relative to the carrier axis. The gears have respective pitch circles and the circumference of the ring-gear pitch circle is a whole-number multiple of the circumference of the planet-gear pitch circle. A support carried on the wheel is coupled to the planet gear offset from the planet axis so that the support orbits about the planet axis as the planet gear rotates. A suction gripper mounted on the support moves jointly therewith at least radial of the carrier axis. A drive rotates the planet carrier about its axis and thereby displaces the suction gripper past the locations in a hypocycloid having cusps at the locations.

Abstract: The laser beam scans a determined surface of the etched layer to be examined, and the intensity of the reflected laser beam is fed in to a data processing system, across which the information relating to the layer under investigation can be reproduced. The etched layer (2) is arranged on a substrate (1) and irradiated with a laser beam (10). The beam is reflected by transparent layers partly at the surface of the layer (2) and partly at the boundary surface of the layer at the substrate (1). The reflected laser beam is composed of two beams (22,22) as a result. The phase difference of the two reflected beams depends on the thickness of the etched layer. Respectively according to phase position or operational difference, the beam (20,22) strengthen or weaken depending on the etching, to alter the intensity of the resultant reflected laser beam.

Abstract: An apparatus is provided for the conveyance of preforms through a heating station to a stretching and blowing machine during the production of hollow articles from thermoplastic plastics materials, means of which preforms having different neck diameters can be heated satisfactorily and extremely uniformly without major modification of the apparatus. This is achieved by providing two endless toothed sections extending parallel to each other and have preform pick-up means mounted thereon. The preforms are collected and retained in position by the pick-up means as they pass through the heating station. The mutual spacing of the belts and, hence, of the pick-up means from one another and from the heating devices is adjustable. A further pair of endless drive belts are provided which rotate the preforms at desired circumferential speed about their own axes as they pass through the heating device so as to promote an even distribution of the heat in the preforms.
