摘要:
This system for generating message transformation and validation software uses interface definition documents as inputs. An interface definition consists of an internally consistent set of message definitions, data dictionary entries, transformation rules, and validation rules. A user-friendly graphical user interface provides the requirements engineer or other user with the ability to specify these documents. This graphical user interface is a structured table and rules editor that allows the requirements engineer to enter and validate interface definitions to ensure that the definitions meet certain predetermined requirements. The generation system takes the interface definition documents as input and generates various software artifacts to transform and validate messages. W3C XML schemas are generated from an interface definition for assistance with code development, for use as standards-compliant interface definition that can be reused and composed with other schemas, and for validating messages. Extensible Stylesheet Language Transform files are generated from an interface definition to transform and validate messages. These generated software artifacts for message transformation and validation may then be used to implement message-processing systems. One example where this software was deployed is a wireless or local number portability service bureau that permits portability requests to pass from one telecommunications entity to another. The graphical user interface also enables the user to compare interface definitions, generate schema artifacts, generate transformation and validation artifacts, generate test cases, generate message indices, and generate documentation for distribution and review (formats include Microsoft Word, rich-text format, and HTML). Preexisting requirements documents may be converted for use in the present system by parsing and translating the preexisting documents into the interface definition documents. After this conversion process, information that could not be parsed and translated is referred to the requirements engineer or other user, who reenters the information using the structured table and rules editor.

A catcher is provided. The catcher includes a body made from a porous material with a first portion of the body defining a delimiting edge and a second portion of the body defining an area recessed from the delimiting edge. A third portion of the body defines an oblique surface beginning at a location removed from the delimiting edge and ending at the delimiting edge. The area recessed from the delimiting edge includes a surface beginning at the delimiting edge and ending at a location removed from the edge. The surface of the recessed area can be substantially flat and/or include a curved portion.

A catcher is provided. The catcher includes a first section having a first porosity with the first section including an impingement surface positioned substantially perpendicular to a non-printed ink drop trajectory. The impingement surface ending at a terminal edge. A second section having a second porosity and an outer edge is positioned relative to the first section. The terminal edge of the impingement surface extends to at least the outer edge of the second section.

Method and apparatus for removing temporary longitudinal wrinkles (29) from a thin or ultra-thin moving web (11) in a web conveyance machine by bending the web through preferably at least 90 degrees around a cylindrical small-radius air bar (13, 35, 39, 61, 63, 65, 73, 79) and for preventing permanent creases from forming in the web by disposing the air bar with the wrinkle-free web in close proximity to the surface of a contact roller (33, 53, 67, 71) and transferring the moving web across a gap (62) of preferably 1 mm or less between the air bar and the contact roller.

An apparatus having short range motion for gripping and releasing an object utilizes a programmable stepper motor for controlling various short stroke motions of the gripper. Gears associated with each of the at least one gripper jaws supported on a carrier shaft engage a common ring gear that is driven by drive means including the stepper motor which imparts synchronous motion of the grippers for opening and closing about the object.

An apparatus and method having short stroke motion for gripping and releasing an object utilizes a programmable stepper motor for controlling various short stroke, generally arcuate motions of the gripper. Gears associated with each of the at least one gripper jaws supported on a carrier shaft engage a common ring gear that is driven by drive means including the stepper motor which imparts synchronous motion of the grippers for opening and closing about the object.

A clamping device for clamping a punch block to a jaw of a punch press assembly where the action of clamping does not disturb the alignment between the punch block and the die. The device includes a pair of cams residing in a stacked relationship with each of the cams having a tapered aperture therethrough. A bolt passes through the tapered apertures of both cams and through a bore in the jaw to engage a threaded orifice in the punch block. Each of the cams has a generally cylindrical cam surface with a flat formed therein. Once the punch block is properly aligned with the die, the bolt is lightly tightened with the flats of the two cams in planar abutment with one another such that the cylindrical axes of the cams are separated by a first distance. The cams are then rotated with the lower one of the cams rolling on the surface of the jaw. Rotation of the cams moves the flats out of abutment with one another such that the axes of the cams become separated by a second distance which is greater than the first distance causing the upper one of the cams to bear against the head of the bolt thereby placing the bolt in tension while imparting no substantial force perpendicular to a longitudinal axis of the bolt.

Equipment (10) for packaging a plurality of articles (1) has a rotatable drum (12) for supporting the articles (1) in one of a plurality of spaced through openings (14) along the circumferential portion (22) of the drum (12). First and second sources (30,32) of first and second webs (16,18), respectively, supplies the webs sequentially under continuous tension towards one of the plurality of through openings (14). By passing the webs (16,18) through respective serpentine paths (28,30) prior to delivery to one of the plurality of through openings (14) provide the desired continuous tensioning level on the webs (16,18). An article dispenser (40) is provided to dispense one of the plurality of articles (1) into one of the plurality of through openings (14) when one of the first and second webs (16,18) generally covers the through opening (14) forming a seat for article 1. Thereafter, and in sequence, the other of the first and second webs (16,18) overwraps the article (1) seated in the through opening (14). A sealing means (46) is provided to sea the webs (16,18) about the article forming a packaged article. A punch means (150) cooperating with the drum (12) is employed to relieve the packaged articles in sequence from the through openings (14).

A web (14) of material such as photographic film is supplied continuously from a stock roll (16) into an infeed vacuum box (24) from which the web passes into an intermittently operated perforator apparatus (30) through which the web is drawn intermittently by a high performance vacuum drum (32) which feeds the web into an outfeed vacuum box (34) from which the web passes continuously to a rewind stock roll (44) or to other intermittently operated processing apparatus. Various patterns of widely spaced perforations and leader/trailer sections may be provided in the stationary web, which moves at high web speeds and accelerations between operations of the perforator apparatus.

Non-contact air film conveyors are suited for conveying elongated strips (46) of web material such as photographic film and include a track plate (12) having gas flow apertures (20,24; 72,74) extending through its thickness at angles to the surface of the track plate (.alpha.,.alpha.') and to the direction of movement of the strips (.beta.,.beta.', .gamma.). By directing air flow through some apertures (72,74) counter to the direction of movement, speed and acceleration control is achieved independent of the support given to the strips by air flow through other apertures (20,24). Baffles (28-36) and curved side walls (70,96) direct air back onto the film to flatten it during movement.
