Abstract: CIRCUITS FOR DETECTING FRAMING BITS        IN A T.D.M. BIT STREAM     Abstract of the disclosure A framing circuit is dislosed for detecting framing bits in a t.d.m. bit stream having an extended DS1 framing format.  The circuit comprises a RAM for storing in respect of each of the 772 time channels the five most recent information bits of the time channel and three other, candidate, bits which represent the likelihood that the particular time channel carries the framing bit pattern.  The current and five stored information bits of each time channel are checked to detect the six-bit framing bit pattern.  The candidate bits have their value increased or decreased, within predetermined limits, in dependence upon whether or not a phase of the framing bit pattern is detected, and the updated information and candidate bits are stored in the RAM.  The modification of the candidate bits in this manner is effected in only every third 772-bit frame.  A framing signal is produced in dependence upon the candidate bits.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE A novel asphalt compacting machine of the type having a chassis, a drive roller, e.g. at the rear and a steerable rolling compaction mechanism, e.g., at the front, is provided herein.  The improvement resides in the provision of a front, preferably steerable, rolling compaction mechanism which comprise two longitudinally-spaced-apart tandem rigid drums, preferably free-wheeling, which extend across the entire lateral width of the chassis.  The drums entrain an elastomeric, e.g. rubber, asphalt-compaction belt therearound.  A lower means, e.g. a flat plate, is operatively associated with the rolling compaction mechanism and is disposed between the rigid drums to engage substantially the entire bottom inner surface of the belt between the two rigid drums.  In this way, substantially the entire outer bottom surface of the belt between the two rigid drums is urged downwardly into pressure contact with the asphalt being compacted, thereby to provide a flat, pressure-applying surface.          Newly laid asphalt paving compacted with such a compaction machine shows substantially no cracks therein.

Abstract: A B S T R A C T     A vibratory temperature transducer includes a pair of elongate, generally parallel bars coupled together at one end in a type of tuning fork arrangement  The bars each have a thickness of t, a width of w and a length between free and fixed ends of L.  The distance between the free end and the point where the bars are coupled together is m.  Apparatus is provided to cause the bars to vibrate in torsional opposition, where the frequency of vibration is generally a function of temperature.  Apparatus is also provided for determining the frequency of vibration of the bars so that when the bars are subjected to a change in temperature, the temperature can be readily determined by simply determining the magnitude of the frequency change.  By careful determination of the dimensions L, m, t and w, spurious modes of oscillation of the transducer, which cause a reduction in the mechanical Q and thus an erroneous reading of temperature, are avoided.

Abstract: TERRAIN/SEASCAPE IMAGE GENERATOR    WITH MATH MODEL DATA BASE Abstract of the Disclosure A technique for the real-time computer generation of visual scenes of rolling terrain and sea waves is based on a view ray approach wherein an azimuth sweep is defined and an image profile is generated by incrementing range steps from the view point but employs a data base which is an on-line math model consisting of a summation of cosine functions rather than a grid data base.  Math models are generated separately for both land and sea elevation posts for the scene to be generated.  A horizontal field of view is defined as a predetermined number of increments between sweeps perpendicular to a boresight from a view point, and a vertical field of view is defined as a predetermined number of increments between view rays perpendicular to the boresight from the view point.  The change in range is incremented along the boresight from the view point, and for each range increment, the view ray is stepped down by an increment corresponding to an increment change in the tangent of the view angle.  An elevation value of the view ray is accumulated for each incremented change in the tangent of the view angle.  For each range increment, the math model forthe land elevation posts is compared with the math model for the seal elevation posts, and the larger of the two is selected.  At each range increment, the accumulated elevation value of the view ray is compared with the selected math model of elevation posts and, if a view ray strikes the selected elevation post, the data for that post is read to a display; other-wise, the math models of the land and sea elevation posts are incremented.

Abstract: ABSTRACT OF THE DISCLOSURE            Described herein are a method for generating electronically controllable color elements and a color display based on the method, comprising a light gate matrix (9), and a light source system with a set of primary color sources (6, 7, 8) for the primary colors (R, G, B), and control circuits (1...4) for controlling the transmission of light gates in the light gate matrix (9) for a level corresponding to the intensity of the respective primary color in the composite color spectrum of the displayed picture element. In accordance with the invention, the primary color is generated by pulsing the primary color sources and using only one light gate per picture element for controlling the primary color intensities at the picture element. The present invention facilitates, among other things, perfect color convergence, improved light transmission efficiency, and simpler production technology for transmission type color displays, due to single light gate construction of the controlled light gate matrix (Figures 1a and 1b).
