Abstract: ABSTRACT             A cycle control for plastic injection molding machines.  All time-responsive machine controls are eliminated by initiating or terminating machine functions in response to actual, physical properties experienced by the machine or by the plastic or in the mold, rather than in response to elapsed-time intervals.  Means are provided for changing the injection pressure to the holding pressure when the pressure in the mold cavity reaches a predetermined pressure, means are provided for ending the holding pressure and initiating the cold/cure portion of the cycle in response to actual, physical conditions of the plastic in the mold, such as pressure or temperature, and means are provided for opening the clamp to eject the molded part and thus end the cold/cure portion in the mold, such as pressure or temperature.  The  machine cycle is thereby completely independent of time, and cycle time may be minimized.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved thread-forming sheet screw is provided.          It includes a screw head and a threaded shank formed of a blank by rolling and connected at its top to the screw head.  A substantially pyramidal end extends integrally from a bottom of the threaded shank to terminate in a point with a maximum diameter of such pyramidal end being not larger than a blank diameter of the blank.  The pyramidal end has a tip portion disposed adjacent the point, and a base portion disposed between the tip portion and the bottom of the threaded shank, the tip portion being of a substantially regular polygon in cross section having at least five edges and at least five flat sides extending divergently from the point to the base portion.  The base portion is of a substantially regular polygon in cross section having at least three sides and at least three rounded ridges with curved outer surface with each of the sides of the base portion being connected with a pair of adjacent rounded ridges of the base portion so as to provide a smoothly continuous contour line, the tip portion being provided with more sides than the base portion.  The curved outer surface of each of the rounded ridges becomes wider as it approaches the bottom of the threaded shank thereby producing a curvature of the curved outer surface varying so as to be progressively increasing in radium toward the bottom of the threaded shank.  This provides a self-tapping screw which enables the formation of a protrusion of the desired height without the development of undesirable splits or cracks around the aperture.

Abstract: ABSTRACT In a digital scan converter for displaying video data provided by a radar sensor on a raster scan display, the video data is stored in a radar input buffer at addresses corresponding to the pattern according to which the field of view of the radar sensor is scanned, and taken over in a random-access memory. The random-access memory consists of N x N submemories, all containing a x a memory elements and all being simultaneously accessible.  For the range scan in any azimuth value (?) the range considered is divided into n (n?N) segments of each k range increments .DELTA.r, where the length k.DELTA.r of each of said segments equals at least the range represented by "a" memory elements, multiplied by a factor  .  An address generating circuit generates the addresses x = xc + (lk+m).DELTA.r cos ? and y = yc + (lk+m).DELTA.r sin ? where xc and yc represent the coordinates of the radar sensor position, l = 0, 1, 2, ..., n-1 in each memory cycle, and m = 0, 1, 2, ..., k-1, to accommodate the data read from the input buffer in the random-access memory at locations corresponding to the display line pattern to be realised on the raster scan display.  The relevant data for each picture line is read from the respective N submemories simultaneously and placed in a picture-line memory storing the data of a picture line in order to be readout in the sequence as required for representation on the raster scan display.

Abstract: ABSTRACT OF THE DISCLOSURE A gas turbine combustion chamber having a primary zone comprising a series of separate axially extending tubular sections with, the downstream marginal portion of each section relieved within an axially coextensive upstream marginal portion of the succeeding section to define an annular axially extending passage therebetween for admitting a film of cooling air for cooling the internal walls of the chamber.  The coextensive portions of adjacent sections are supported in their spaced relation by a wiggle strip disposed therebetween having walls separating the annular passageway into a plurality of individual flow paths.  The downstream marginal portion of each tubular section extends axially beyond the downstream edge of the wiggle strip walls a distance sufficient for dissipation of wakes formed in the flowing cooling air by the walls to thereby increase the cooling effectiveness of the air film once it exits the annular passage.  This downstream portion beyond the wiggle strip walls is also tapered to a minimum thickness edge to increase the effectiveness of the cooling air by reducing wakes formed by the terminal edge of the tubular section that would otherwise also cause early mixing of the cooling air with the combustion gases.
