Abstract: A printing system comprises a media transport device which holds print media, such as paper, against a movable support surface, such as a belt, by vacuum suction through holes in a vacuum platen and transports the print media though a deposition region of one or more printheads, which deposit a print fluid, such as ink, on the print media. The printing system comprises an airflow control device comprising dampers that are moveable along a direction perpendicular to the vacuum platen between an undeployed configuration and a deployed configuration, each damper blocking at least one row of the holes in the deployed configuration. The airflow control device also comprises actuators to move the damper(s). The actuator(s) are controlled to selectively move the damper(s) between the undeployed and deployed configuration based on a position of an inter-media zone between adjacent print media held against the movable support surface.

Abstract: A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a printhead module comprising a plurality of printheads to eject a print fluid to a deposition region. The media transport device holds a print medium against a movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system is arranged to flow air toward the movable support surface at locations upstream and downstream of the printhead module, based on a location of a print medium relative to the printhead module.

Abstract: A printing system comprises an ink deposition assembly, a media transport device, and an airflow control system. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper, transported through a deposition region. The media transport device holds the print media against a moving support surface, such as a belt, by vacuum suction through holes in the media transport device and transports the print media though the deposition region. The airflow control system comprises a damper and an actuator configured to move the damper along a cross-process direction. The damper blocks airflow through a subset of the holes along a side of the media transport device, the subset varying based on a position of the damper. The damper is moved to change the subset of the holes blocked by the damper based on a size of the print medium.

Abstract: Methods, systems and devices are provided for utilizing user movement data obtained from one or more wearable sensors during physical activity to compare individualized changes overtime, for example typical versus atypical movement patterns, with subgroup analyses for assessing changes between other users in order to develop an assessment of movement for, for example, tracking injury risk, performance, and/or rehabilitation. The movement information may comprise multi-sensor, high dimensional datasets. Techniques are provided for integrating human movement data from one or more wearable sensor with one or more additional data sources to define an individualized movement profile of a user's movements. The user or another individual may be notified when the user's movements deviate from this individualized movement profile.

Abstract: A wheel for rolling bags and associated assembly methods are provided. The wheel includes a non-inflatable outer tire, a plurality of segments positioned inside the tire concentrically about an axis of the tire and supporting an inner surface of the tire, and first and second rims capping first and second openings in the tire, respectively, and supporting the plurality of segments.

Abstract: A heat shield arrangement (12) for a roller table (2) comprising respective upper and lower series of heat shield panels (32,34,36,18) above and below a hot material path (42) along the table. The lower series of panels (18) includes at least one panel that is displaceable to permit a greater radiation loss from a central region of the path (42) than from laterally outer regions to each side of the central region. The upper series of panels includes at least one central panel (34) and at least two laterally outer panels (32,36) on opposite sides of said central panel (34), the outer panels (32,36) being suspended from a primary support structure (26) and said central panel (34) being suspended from an auxiliary support structure (30) displaceable relative to the primary support structure (26) to raise said central panel (34) relative to the outer panels (32,36). By these means a more uniform lateral temperature profile can be obtained even for thick transfer bars.

Abstract: An apparatus and a method for controlling the lateral temperature control of hot material on a roller table of a hot roller mill employs adjustable heat-insulating panels below the hot material path, between the rollers of the roller table. Between each successive pair of rollers a number of the heat-insulating panels are arranged side by side, as a group spanning the width of the table. At least away from the entry end of the table, the panels of each group can be displaced selectively to allow a greater loss of heat from a central region of the hot material between its side edges than in the side edge regions themselves. The selective displacement of the panels can be preprogrammed to be determined by the characteristics of the hot material entering the roller table.

Abstract: Rider bar assembly for a product support beam of a reheat furnace of the type suitable for reheating steel product such as slabs, blooms, bar stock and semi-finished products. The assembly has a rider bar which defines an upper contact surface on which a product to be heated is receivable, a base component which has an upper region with which a lower region of the rider bar is contiguous and support means by which the base component and the rider bar thereon are mountable on a product support beam of the furnace in which the product is to be reheated. The rider bar is formed of a high temperature resistant, solid ceramic material which is a low porosity and which has sufficient compressive strength for supporting part of the load of the product when the letter is received thereon and also on the rider bar of other assemblies mounted on the same and other beams.

Abstract: A roller table provides a hot material path and heat insulating panels are disposed below that path, between successive rollers of the table. The panels are displaceable between a raised, operative position close to the hot material path and a lower, inoperative position in which the panel upper faces are turned away from said path. The panels remain within the width of the roller table when they are so retracted. Further heat insulating panels are displacably mounted on a frame above the path. Temperature sensing means with the top panels actuate the displacement of both the upper and lower panels.

Abstract: Heat shield panels arranged below a hot material path are supported in a manner which allow limited movement. Carry-over bars at opposite ends of each panel are also displaceably mounted and have bearer elements which lie below the panels. When a carry-over bar is struck by distorted material, it will be momentarily displaced and, through supporting engagement of the bearer elements with the panel, displacement of the panel also occurs, so disturbing loose deposits on its top faces. Occasional agitation of the panels is thereby provided passively and the build-up of deposits on a panel top face can be countered in a manner which allow the angle of slope of the top faces to be reduced.

Abstract: This invention is staging or scaffolding for use within a tank for example a storage tank in chemical plant or in a marine oil tanker, and an assembly of staging comprises a number of platforms each coupled to at least three flexible chains adapted for connection at top and bottom to a side wall or the roof or floor of the tank with the chains extending vertically between the top and bottom fixing points and the platforms extending horizontally and spaced vertically from one another. The assembly can be collapsed and lowered through a hatch in the roof of the tank or can be built up within the tank and the connection at the top may be to a releaseable shackle which remains engaged so long as the chains are supporting substantial weight, but which automatically release when weight is removed so that removal of the staging after it is no longer required can be done quite safely without an operator standing on the staging.
