  • Publication number: 20240119753
    Abstract: A method includes transmitting a request for a computer-readable routing diagram, such as a wiring diagram, a pneumatic or hydraulic line diagram, or an optical cable diagram. The method also includes receiving, in response to the request, a routing diagram including a connectable component and at least a portion of a routing set. The connectable component is associated with both a connectable component identifier and the routing set. The routing set contains one or more routable components, such as electrical circuits, pneumatic or hydraulic lines, or optical cables. Further, the method includes displaying, on a display, the routing diagram and at least the portion of the routing set highlighted. Displaying at least the portion of the routing set highlighted occurs in response to an occurrence of the connectable component being selected from the routing diagram displayed on the display or in response to the request including the connectable component identifier.

  • Patent number: 4781102
    Abstract: The apparatus comprise a generally tubular outer element, a generally cylindrical inner element disposed therewithin and sized relative thereto to provide a generally annular operating space therebetween. An intermediate element is disposed in said operating space and is dimensioned relative thereto to create interference fits with said outer and inner elements and prevent relative movement therebetween. Means are provided to introduce pressurized fluid to the respective element interfaces to expand the outer element within the elastic limit thereof to an extent sufficient to release the interference fits and enable relative outer-inner element movement. Re-locking of the outer and inner elements occurs automatically upon depressurization of the fluid and attendant return of the outer element to its unexpanded configuration. Actuating means to effect relative outer and inner element movement upon apparatus unlocking are also provided, and include means to pressurize the fluid.

  • Patent number: 4549561
    Abstract: A coin sorter is provided comprising a rotatable disc with a resilient surface and a stationary disc having its first surface positioned proximate to the resilient surface of the rotatable disc. Coins placed between the two disc surfaces are pressed into the resilient surface by pressure from the stationary disc. Selected areas of the stationary disc are recessed so as to release coins from their pressed engagement with the resilient surface and thereby allow radial movement of the released coins in response to centrifugal force. The selected areas of the stationary disc which are recessed, guide the coins along a path which results in each denomination of coin escaping from between the two discs at different positions along the periphery of the stationary disc. Recesses and ridges are provided on the underside of the stationary disc which recirculate improperly aligned coins.

  • Patent number: 4531531
    Abstract: A coin sorter is provided comprising a rotatable disc with a resilient surface and a stationary disc having its first surface positioned proximate to the resilient surface of the rotatable disc. Coins placed between the two disc surfaces are pressed into the resilient surface by pressure from the stationary disc surface. Accordingly, coins rotate with the rotatable disc. Selected areas of the stationary disc are recessed so as to release coins from their pressed engagement with the resilient surface and thereby allow radial movement of the released coins in response to centrifugal force. The selected areas of the stationary disc which are recessed, guide the coins along a path which results in each demonination of coin escaping from between the two discs at different positions along the periphery of the stationary disc. Recesses and ridges are provided on the underside of the stationary disc which recirculate improperly aligned coins.

  • Patent number: 4444212
    Abstract: A coin sorting machine in which coins are fed onto the center of a rotating disc having a flexible surface. An annular guide plate is positioned over the disc, being open in the center for receiving coins, and extending outward to the peripheral edge of the disc. The underside of the guide plate is formed with a peripheral stop extending around approximately half of the disc, and a series of discrete radial guides extend over portions of the other half of the disc. The first of the series of guides would have an outer edge differing in radius from the peripheral stop by the diameter of the smallest coin to be sorted, and each succeeding guide would have a progressively smaller radiused outside edge defined by the difference between coins to be sorted by succeeding guides.

  • Patent number: 4086928
    Abstract: A coin sorting machine in which coins are moved by centrifugal force in a single layer and in a single file onto a flexible mat and laterally against an outer raised edge of a rotating disc. The coins are then rotated under a series of coin depressors, each being spaced to engage the inner edge of a particular diameter, denomination, of coin at a discrete peripheral position. As the inner edge of a particular coin is thus depressed into the flexible mat, the outer edge of that coin is raised above the outer restraining edge, and the coin is thus hurled outward above the edge at a discrete peripheral position to thus effect denominational sorting.
