Tilt, tray

Items to be sorted enter the sortation conveyor at a point known as the induction point. (There may be multiple induction points.) In high-volume systems, the induction point is typically fuUy automated the item is automaticeilly identified (often via bar coding the item and using laser scanners) and it is automatically inserted into the sortation conveyor. The insertion mechanism depends on the type of sortation conveyor used. For example, most sortation conveyors (except for tilt tray and cross-belt sorters, described below) require a minimum amount of clearance (or physical distance) between the items to be sorted this clearance is automatically inserted at the induction point, which releases the items with the proper cletuance between them. 

Conveyor Systems. Conveyors are the mainstay of material handling in automated facilities. This trend will continue. Conveyors are comparatively low in cost, easy to install, and flexible. They can also be used for temporary storage and surges. In recent years, specialized conveyors have been developed for customized application, especially for the auto industry. For material distribution, conveyors may carry tilting trays and function as sortation devices. 

Jell-O shots, one of those rare, raucous cocktails you do, not drink, is enjoying improbable popularity this summer in New York, and it s gotten kind of fancy on itself, too. This is not the tilt, slip and slurp finger-food shot dumped from an ice cube tray and set quivering on a paper napkin on the bar, ready to rock. 

Lay unit on its side. Tilt unit back and forth at approximate 45° angles three times to mix the cell suspension. Place unit on its side again to let the suspension settle evenly among the 10 trays. Turn upright. 

Tray tilt affects the liquid flow pattern and the boundaries between the regions (148). 

Under some conditions, vapor velocity maldistribution induced by hydraulic gradient nr tray tilt cam lead to excessive nonuniform weeping (183a Also, see Secs. 6.2.12, 6.2.13). Such excessive weeping can be detrimental to tray efficiency. 

To etch, slip the board into the tub filled with solution. Every few minutes, agitate the board by moving it around or tilting the tray back and forth to move the solution across it. This motion is necessary and makes the etching go much faster. As you do this, you can see the copper disappearing in the areas that are not covered by the resist. 

Whenever possible, tray holes should be avoided in that part of the tray located over the support rings. Having tray holes over the rings reduces the effectiveness of the support, particularly in corrosive services. A support ring should be installed level. Adequate tray levelness cannot be achieved with tilted support rings. 

Sieve tray weeping may be expected to increase with tilting, but tests have shown that this effect is only important when the column operates at liquid flow rates [<5 gpm per inch of weir (250)]. 

Unlevelness may induce liquid maldistribution, and thereby lower efficiency in multipass trays (177). Specifically, it has been stated (211, 399) that a series of multipass trays tilted in the seime direction will suffer a severe efficiency loss. 

Unlevelness may significantly affect the performance of trays operating at low liquid flow rates, and trays that have a low liquid crest and/or a low slot seal (bubble caps). Such features are common in vacuum columns. In most other cases, some unlevelness is not detrimental to tray performance, and a tilt even two or three times the recommended tolerance can often be tolerated. 

Skirt alignment The skirt base support ring is not perfectly even. This unevenness affects the vertical alignment of the column, and therefore also the tray tilt. 

Column bowing Joining all the sections from which the column is fabricated is not perfectly even. In addition, some bowing of the column occurs prior to installation, while the column is horizontal. Either factor may affect the straightness of the column-shell axis, and therefore also the tray tilt. 

Unlevel supports Unlevel support rings or support beams will cause trays to tilt. Correct installation can minimize this effect. Techniques for permitting on-site levelling are discussed in Sec. 7.4. 

Thermal expansion If the column is uninsulated and trays are installed in the morning on a sunny day, one side of the column may become hotter than the other. In a 100-ft column, this can add up to Vi in of tilt to the top tray (250). During normal operation, thermal stresses vary with the time of day and the directions of sunshine and wind this affects tray tilt. 

Measurements are made of the yield stress of two carbopol solutions (density 1000 kg/m ) and of a 52.9% (by weight) silica-in-water suspension (density 1491 kg/m ) by observing their behaviour in an inclined tray which can be tilted to the horizontal. The values of the angle of inclination to the horizontal, 0, at which flow commences for a range of liquid depths, H, are given below. Determine the value of yield stress for each of these liquids.

Tilting of the femoral and/or tibial components relative to the plane of the x-ray complicates radiographic measurement of wear in TKA. Some studies have measured knee wear as the difference in minimum distance separating the condylar surface of the femur and the tibial tray (denoted with arrows). Note that the initial postoperative radiograph (A) shows substantially more tilt of the tibial tray than the radiograph taken 4 months later (B). 

Tilt of a tray support ring over its width shall not exceed 1/16 in. (1.5mm)... 

Both the static-array xenon test chamber and rotating-dmm xenon chambers simulate the effects of outdoor moisture by spraying water onto the test specimens. This method is especially good for simulating the effects of thermal shock or mechanical erosion. In the static-array, test specimens are mounted on a flat specimen tray which is tilted at 5 ° from horizontal. The static-array s water spray covers the specimens uniformly and, because of the near horizontal position of the specimens, the water does not quickly mn off. In the static-array, specimens stay wet during the entire moisture cycle.
