Abstract: CMOS TURN-ON CIRCUIT ABSTRACT OF THE DISCLOSURE        A CMOS integrated circuit which requires a higher and a lower supply voltage source, often includes a parasitic diode commonly in the form of a thyristor which is formed with its anode connected to the lower voltage supply terminal and its cathode to the higher voltage supply terminal.  The present invention is an FET which has its source-drain circuit connected between the lower voltage terminal of the integrated circuit and the lower voltage source, and its gate to the higher voltage source.  This protects the integrated circuit diode from fusing if either passive or dynamic conditions result in the faster voltage rise at the anode relative to the cathode when supply voltage is applied to the integrated circuit, since the voltage at the anode is protected from rising faster than the cathode.

Abstract: ABSTRACT OF THE DISCLOSURE         There is described a new and improved method of fracturing an underground stratigraphic formation penetrated by a well bore including the steps of pumping a stream of liquified gas into the formation to cause the fracturing thereof and then introducing proppants directly into the stream of liquified gas for injection of the proppants into the fractures.  Prior to introducing the proppants into the liquid gas stream, they are cooled and pressurized to the storage temperature and pressure of the liquified gas.

Abstract: La présente invention a pour objet des perfectionnements à un classificateur hydraulique de minerai. Ces perfectionnements se caractérisent d'une part, en ce que le fond de la cuve du classificateur est entièrement détachable pour en faciliter l'entretien et, d'autre part, en ce que toutes les cellules de la cuve sont divisées horizontalement par une longue plaque s'étendant sur toute la longueur du classificateur. Cette plaque est fixée par coïncement entre le fond de la cuve et le restant de celle-ci et est en outre pourvue d'une pluralité de perforations régulièrement espacées sur toute sa surface pour laisser passer l'eau introduite dans le fond de la cuve et ainsi assurer une meilleure distribution de la pression au sein de chaque cellule. La plaque est également pourvue d'un nombre de trous égal au nombre de cellules, chacun des trous étant placé de façon à se trouver au milieu de la cellule qui lui correspond pour laisser passer les particules de minerai descendant à contre-courant à l'intérieur d'un tuyau de décharge monté de façon amovible. Le principal avantage du classificateur hydraulique ainsi perfectionné est la facilité avec laquelle il peut être entretenu et réparé le cas échéant lorsque l'une de ses pièces est abîmés ou usés par frottement du minerai classifié.

Abstract: Abstract A flow line bundle assembly includes a plurality of con-duits disposed within a tubular covering member.  The tubular covering member is sealed at its ends before being placed in a body of water, so that the flow line bundle has a slight positive buoyancy when submerged in the body of water.  Weights are then added to the flow line bundle to cause it to have a neutral buoyancy at a position slightly above a floor of the body of water.  The flow line bundle is then towed from its point of construction, through the body of water, to the loca-tion where it is to be installed.  During a first method of towing, if an obstacle located above the ocean floor is approached, a trailing tug increases a restraining force applied to the flow line bundle so as to lift it above the obstacle as the flow line bundle  passes over the obstacle.  A second method of towing maintains the flow line bundle at a constant depth below a surface of the body of water so that the bundle will clear any obstacles on the floor of the body of water.  After the flow line bundle is connected between a subsea wellhead and a producing platform located within the body of water, the space between the conduits and the tubular covering member is flooded to sink the flow line bundle to the ocean floor and to provide heat transfer between the conduits and the tubular covering member,

Abstract: ABSTRACT     A special form of fluid cyclone in which the velocity energy in the exit fluid is converted into exit pressure thus permitting the device to discharge to atmospheric pressure or a higher pressure while a vacuum may exit in the central core of the vortex.  The result is achieved by use of a curved passage at the exit which starts as a coaxial space and grad-ually expands and turns outward to become a circular space between two disks.  The removal of reject material to atmospheric pressure with a vacuum at the core may be achieved by limiting the restriction in cross-section of the bottom core such that the pressure is atmospheric and allow it to leave through a space between the end of the cone and a blunt shaped surface. The above special form of fluid cyclone operates particularly well, because of reduced energy losses, when employed in a multiple arrangement in which the tangential velocity energy of fluid entering the barrel of the individual cyclone units is created by fluid flowing at larger radius such as to create a pattern of multiple vortex flow.  The vortices are in a chamber providing a common inlet to  a  plurality of cyclone units with the vortices centering on the individual units.  The special arrangement of fluid cyclones is in a geometry similar to that of a vortex trail with an even number of units of opposing vortex direction.  The same type of arrangement; i.e. having all of the units discharge into a common chamber, leads to further energy recovery in fluid leaving the fluid cyclones.

Abstract: ABSTRACT OF THE DISCLOSURE        A tractor vehicle transmission is provided with a two piston brake where each piston operates in opposite directions.  A gear is located adjacent the brake which is located in proximity to a wall of the transmission.  Thus upon actuation the brake will contact the gear causing re-tardation of the gear, its attendant shaft, and the trans-mission as a whole allowing simpler shifting of the trans-mission.  The piston force against the brake is opposed by a second piston having a spacer means that contacts the transmission wall upon actuation.

Abstract: Abstract of the Disclosure Apparatus for producing a preselected final image in a travelling magnetic image-storage medium, which image is formed of an arrangement of individual magnetic image units and line segments formed of a plurality of linearly disposed contiguous units having a predetermined center-to-center spacing.  Adjacent units in adjacent line segments have substantially the same predetermined center-to-center spacing when viewed in a direction substantially normal to the direction of travel, and also have a known maximum actual center-to-center spacing.  Plural magnetic writing heads, each capable of producing an image unit, are distributed to have, when viewed in a direction substantially parallel with the direction of travel of the medium, a center-to-center spacing equalling that of contiguous units in a line segment.  The actual center-to-center spacing between heads capable of forming adjacent image units in a line segment exceeds the mentioned center-to-center spacings between adjacent units. A controller receives data defining a desired final image from an input channel, and develops time-coordinated signals which energize heads selectively at appropriate times as the medium travels past the heads to effect recording on the same of image units and line segments to form the final image.  The heads may be distributed in one or more side-by-side adjacent columns, each extending along a path  oblique both to the direction of travel of the medium, and to the line along which a line segment may be written.

A workpiece is loaded into the mold by positioning end plates on the workpiece and locating the combination on the fourth quadrant by positioning of the end plates on locating pins projecting from a frame member or tilt beam associated with the fourth quadrant.  Slide assemblies are then moved into workpiece engaging positions on each end of the workpiece to accurately locate the workpiece relative to the fourth quadrant.  The fourth quadrant with the workpiece locked thereon is then moved into a mold closed position for molding. Following the molding cycle, the fourth quadrant is then lowered to a mold open position and an ejection mechanism is used to elevate the workpiee and end plates above the locating pins for easy removal of the workpiece and end plates from the fourth quadrant.
