Abstract: Abstract A scanning CRT visual display system 10 is provided in which the operation of the CRT controller 21 which provides video blanking pulses and horizontal and vertical sync pulses (at B, 25 and 26) for controlling the CRT display is temporarily halted when a larger than normal vertical spacing between horizontal scan lines is desired.  During the time that the operation of the CRT controller is halted, which is accomplished by the selective blocking of clock timing pulses (at 33) to the controller 21, an auxiliary synchronous counter circuit 62 effectively counts the clock timing pulses and provides a substitute horizontal sync pulse (at G) for the CRT display such that during the implementation of a larger than normal vertical step for the scanning CRT display system, horizontal sync pulses are always provided even though the operation of the CRT controller is temporarily suspended during this time.

Abstract: ABSTRACT      This process produces light diffracting patterns, such as holograms, which may be incorporated into a printed doc-ument and which are visible in non-coherent light so that a person inspecting the document may readily determine whether the light diffracting pattern is present and thus whether the document is genuine.  A laminated sheet material is prepared for receiving an embossment of the light interference pattern.  The laminated sheet includes a support layer, a release coat, at least one layer of thin transparent material over the release coat, and a reflective layer less than 1,000 Angstrom units thick, bonded to the surface of the transparent layer farthest from the support layer.  A die carrying the light interference pattern in relief is impressed into the reflective layer and the adjacent transparent layer to form an embossed light diffracting pattern.  The laminated material then has its reflective layer covered with adhesive and pressed against a flexible substrate such as paper, with heat and pressure. The reflective layer adheres to the sub-strate and the support layer separates from the transparent material by melting of the release coat.

Abstract: ABSTRACT The method for testing the linearity and other raster scan geometry of a television display apparatus or a tele-vision camera.  The method is used when the display appara-tus or camera being tested has a scan rate which cannot match the currently used EIA linearity chart due to funda-mental differences in the raster structure and can also be used on the 525/60 scan rate as used in broadcast mode without requiring the unusual alternate count required for the EIA chart.  In testing a display apparatus, a bar or dot pattern is formed on the screen by a test pattern generator wherein the spacing of the horizontal rows of dots or bars is selected to correspond to a particular scan rate.  A linearity chart having a geometry corresponding to that scan rate is selected from a plurality of test charts and the image thereof is projected on the screen to match, as closely as possible, the dots or bar intersections on the screen.  The amount of non-linearity can be quantified by noting the positions of the dots or bar intersections relative to the concentric annuli of each graphic element making up the chart.  The television camera can be tested in a similar fashion by viewing the selected linearity chart and superimposing the image produced by the camera with the dot or bar pattern of the selected scan rate produced by the test pattern generator.

Abstract: Ce procédé est du type dans lequel on comprime en au moins deux stades un mélange de fluides frigorigène composé de constituants de volatilités différentes et dans lequel, après le dernier stade et après au moins un stade intermédiaire de compression, on condense partiellement le mélange, on détend les fractions condensées et on les vaporise en échange de chaleur avec le fluide à refroidir avant de les comprimer de nouveau. Suivant l'invention, on effectue l'une au moins des opérations de condensation en envoyant dans une colonne de distillation le mélange sortant de l'étage correspondant du compresseur. Ceci permet de diminuer l'irréversibilité thermodynamique du cycle frigorifique et, par suite, de réduire l'énergie spécifique de refroidissement. L'installation prévue pour la mise en oeuvre de ce procédé comprend un circuit frigorifique dans lequel circule un mélange frigorigène et qui comporte un compresseur à au moins deux étages pourvus chacun d'un réfrigérant et après le réfrigérant du dernier étage et après celui d'au moins un étage intermédiaire, un séparateur liquide-vapeur. Entre le refrigérant associé à l'un au moins des séparateurs et l'étage de compresseur correspondant est montée une colonne de distillation qui est chauffée par le gaz comprimé par cet étage de compresseur et qui reçoit en reflux le liquide issu du séparateur.

Abstract: ABSTRACT             TRANSMISSION RATIO SELECTOR MECHANISM     A transmission ratio selector mechanism having an upper manually operable gear lever (120) which is mounted (139, 250) inter-mediate its ends for pivotting about two perpendiculr axes and a lower lever member (134) which is pivotted in a fixed mount (136) at its lower end (135) and is connected at its upper end (137) with the lower end (138) of the gear lever (120).  The lower lever (134) is interconnected (133) intermediate its ends with a ratio selector shaft (112) whose longitudinal axis passes through the fixed mount (136). Pivotting of the gear lever (120) about one of the perpendicular axis causes axial displacement (W1, W2) of the selector shaft (112) in a direct-ion parallel to its longitudinal axis and pivotting of the gear lever about the other perpendicular axis causes turning of the selector shaft about its longitudinal axis to move one or more ratio selector forks (101, 102).            The gear lever (120) also has a range change position (H/L) which can only be reached when the associated transmission is in a neutral condition.            The mounting (400) of the upper lever (120) may also vibra-tionally isolate the upper lever relative to the lower lever (134).

Abstract: FILL GATE FOR GRAIN BINS AND THE LIKE            ABSTRACT         A wedge shaped hollow float is mounted by one end to a channel bolted to the inside of the sloping roof of a grain bin approximately two feet from the top there-of.   A curved rod is pivotally secured by the inner end thereof to the other end of the float and extends through the channel and through the roof and has an indicating disc on the outer end thereof.   As the bin fills, the angle of repose of the grain engages the other end of the wedge shaped float and gradually lifts it as the bin continues to fill.  When the indicator is fully extended, a rod and disc indicates to the operator that the flow of grain to the auger hopper should be shut off and the two foot space at the top of the bin is sufficient to hold the grain left in the auger and in the hopper thus avoid-ing  any  spillage.

Abstract: ABSTRACT          The bearing shell of a multiple-face hydrodynamic radial plain bearing has an internal surface which is composed of several identical arcuate sections whose radii of curvature slightly exceed the radius of curvature of the rotary component within the shell.  The central portion of each section is nearer to the external surface of the rotary component than the other portions, and each such central portion has a hydrostatic pressure chamber receiving the liquid which is conveyed by a fluid flow machine wherein the bearing shell is used or a different liquid, such as a lubricant.  The axial length of each chamber is between 40 and 80 percent of the length of the bearing shell, and the width of each chamber is between 20 and 80 percent of the length of the respective section, as considered in the circumferential direction of the shell.  The provision of pressure chambers contributes to the ability of the bearing shell to prevent vibration of and/or to otherwise stabilize the rotary component as well as to take up pronounced bearing forces.
