Abstract:
A portable assembly for supporting cheese hoops in an inclined position from the vertical and including means for pressing the hoops so as to press the whey therefrom and permit it to drain downwardly from one hoop to the other to be collected therebelow. The frame includes support members for removably but firmly holding the hoops as they are being pressed by cylinder and piston units located at the top of the assembly. Control means are provided for actuating the units in extending or contracting directions. The gases actuating the cylinder and piston units are discharged to the floor of the apparatus, preventing their contaminating the hoops or curds that would be possible by release above those hoops.
Abstract:
A self-cleaning nozzle for lithographic printing dampeners includes a central liquid duct and an air expansion chamber surrounding the liquid duct and defined by a cylindrical wall closed at an entrance end by a baffle having circumferential slits therethrough and at an exit end by a planar end wall spaced from the termination of the liquid duct and forming a mixing corridor therebetween. The end wall is positioned perpendicular to the liquid duct and to the direction of air traveling through the expansion chamber, thereby increasing turbulence in the air to more effectively break up the liquid stream into fine droplets. A slot orifice is formed in the end wall and is defined by a peripheral surface which forms an acute angle with an inner surface of the end wall and an obtuse angle with the outer surface thereof.
Abstract:
A designer of a CAD model is automatically notified when parameter limits or tolerances are violated during the iterative design process. The efficiency in the design of a complex model is much improved from the automatic notification, because it enables the user to detect violations of parameter limits and tolerances as soon as they occur.
Abstract:
One or more embodiments of the invention provide a method, apparatus, and article of manufacture for defining mating properties of a graphical component in a computer-implemented drawing program. An option to create a first constraint interface for a first geometric characteristic of a first component is initiated. In response to the initiation, a dialog window for specifying settings for the first constraint interface regardless of whether a second constraint interface is currently displayed is displayed. The settings define mating properties for how the first geometric characteristic of the first component mates with the second constraint interface. Once specified, the first constraint interface of the first geometric characteristic is persisted with the first component.
Abstract:
A mining cable coupler has a hollow, cylindrical body. There is an entrance fitting for an electrical cable at a first end of the body. A plate-like insulator mount extends over the body near the second end and has insulator receiving apertures with annular recesses extending thereabout and inwardly from the second end of the body. There is a plurality of separate, tubular insulators. Each insulator has an annular outer projection extending thereabout and received within one of the recesses of the insulator mount. There is an annular seal fitted between each recess and the insulator therein. There is an elongated electrical contact within each insulator. A metal member has a tube extending about each insulator. An inner portion of the member is against the insulator mount. The inner portion has an aperture for each insulator smaller than the annular outer projection thereof and closely fitted about each insulator adjacent the projection. Fasteners releasably secure the metal member to the insulator mount.
Abstract:
A printing press, especially of the offset newspaper printing type, includes an anti-wrinkle roller to function in cooperation with a web of paper being printed by the press. The roller has a pair of sections which are each independently adjustable eccentrically with respect to a common central axis. The roller is mounted transverse to the web. The eccentrically adjustable sections of the roller are manipulative to compensate for uneven tension across the width of the web so as to provide uniform tension and thereby reduce wrinkles produced by uneven tension in the web. Manual adjustment knobs or remotely controlled motors may be alternatively utilized to selectively adjust the eccentricity of the roller sections relative to one another and to the central axis thereof.
Abstract:
Web letterpress equipment is converted to offset lithographic equipment by modification of a driven letterpress impression cylinder to receive an offset blanket, thereby producing an offset blanket cylinder. A letterpress plate cylinder is modified to become an offset plate cylinder with accompanying offset inking and dampening equipment. In one embodiment, a driven letterpress plate cylinder of a color hump is packed to become an offset impression cylinder cooperating with the offset blanket cylinder. In a second embodiment, the letterpress plate cylinder of the color hump is modified to an offset color plate cylinder and a driven offset impression cylinder is added to cooperate with the offset printed on one side of a web. When used in combination with similarly converted letterpress plate, impression and color hump plate cylinders, at least three colors may be offset printed on one side of a web or multiple colors printed on opposite sides thereof. The press tower is rewebbed to print with proper registration in the bight between the respective offset blanket cylinders and offset impression cylinders.
Abstract:
A computer controlled system for the diagnostic testing of two wire telephone lines. The system comprises a control means having a programmed digital computer and associated memory, a line test network, a user station and an interface for interconnecting these elements and one or more telephone exchanges and a plurality of two wire telephone lines extending from the exchanges. The line test network is responsive to the digital computer and includes means for generating a plurality of line characteristic signals during a test cycle for a selected line. The characteristic signals are representative of the resistance and reactance between a reference potential and each of the two wires of a selected line, and between the two wires of the selected line. The line characteristic signals are transformed to signals indicative of the line identity, line length, type of termination, type and location of equipment connected to the line and existence, approximate location and type of faults along the line. The latter signals are categorized according to selected line condition, and stored in the memory for selective retrieval in response to control signals generated by a user at the user station.
Abstract:
A portable assembly for supporting stacks of cheese hoops in an inclined position from the vertical and including means for pressing the stacked hoops so as to press the whey therefrom and permit it to drain downwardly from one hoop to the other where it is collected by means of an inclined floor. The frame includes support members for removably but firmly holding the stacks of hoops as they are being pressed by cylinder and piston units located at the top of the assembly. Control means are provided for actuating the units in extending or contracting directions.
