Fluid control panel

At present, the well fluids from the four installed subsea wells flow through 4 in. 10-cm Coflexip seabed lines to the SALS mam told, then through a six-bore product swivel, and finally, through the mooring yoke to the receiving manifold on the FPSU. Well subsurface safely valves and wing valves are controlled hydraulically from a control panel on the FPSU deck by control lines routed through a 20-borc swivel on the SALS. 

The finite control-volume dimensions as illustrated in Fig. 2.13 may be a potential source of confusion. While the stress tensor represents the stress state at a point, it is only when the differential control volume is shrunk to vanishingly small dimensions that it represents a point. Nevertheless, the control volume is central to our understanding of how the stress acts on the fluid and in establishing sign conventions for the stress state. For example, consider the normal stress xrr, which can be seen on the r + dr face in the left-hand panel and on the r face in the right-hand panel. Both are labeled rrr, although their values are only equal when the control volume has shrunk to a point. Since the stress state varies continuously and smoothly throughout the flow, the stress state is in fact a little different at the centers of the six control-volume faces as illustrated in Fig. 2.13 where the...

Instrumentation and control. Operation of a fluid cracking unit is simplified by the use of automatic controls. As a further aid, graphic panel-boards are sometimes employed which utilize small indicating instruments located at the appropriate positions in a simplified flow diagram of the process (68,309). Audible and visual alarms, as well as automatic controls for emergency shutdown of the unit, are often provided (202). 

In order to check the paintability of parts molded with Q2-7119, test panels molded with and without silicone fluid were post-cured, solvent wiped with toluene, primed with PPG Durethane 600 Primer and then top coated with Durethane 300 blue metallic flake or white. Painted samples were exposed for 2 years in Florida Direct Black Box 5° South and then evaluated for appearance and adhesion. Results of these tests showed no difference between control and IMR-containing panels. Paint adhesion was excellent. 

To avoid repetition of our company s trade name we will, in this chapter, use a generic name to describe the equipment and its process. We will call it the "Fluid Film Process". The fluid film process permits a high speed continuous treatment of sheet, strip, panel and billet material requiring cooling, heating, pressure confinement or shape and surface control. Many products presently manufactured in molds or platen presses can now be much more rapidly produced continuously on machinery incorporating fluid film processing. 

Where +1/32 inch (+0.8 mm) has been the standard thickness tolerance for 4 foot (1.22 meter) wide panels produced in double belt lines, the standard for the fluid film process is +0.010 inch (+0.25 mm). At times, an accuracy within +.005 inch (+.127 mm) has been achieved. Such accuracy is possible because of the precision and rigidity of the tunnel construction. The platens are reinforced weldments, stress relieved after welding and then ground and chrome plated. They are separated by precise gage blocks to form the two faces of the tunnel. Deflection is practically non-existant since the foam pressure on the platen is balanced by the fluid pressure within the platen reservoir. The fluid film is accurately controlled to maintain it at a normal working thickness of 0.005 inch (0.127 mm). 

The fluid film processor can match any size, speed, formulation capability, temperature, pressure, energy use, control, and duty capability of a double belt conveyor for the production of cellular panel produced of urethane, cyanurate or phenolic and two flexible skins. It will easily fit into the same space and as a replacement may then offer the capability of higher speeds, higher densities, greater accuracy, smoother surface and greater core material versatility. In addition, its quietness safety and reduced maintenance make the replacement a welcome change. 

Figure 4 Analysis of neutrophils in synovial fluid by flow cytometry. Synovial fluid was obtained from a control mouse and a mouse with established arthritis (days 7 after K/BxN serum injection). Cells were stained with Ly-6G antibody and analyzed by flow cytometry. Left panel green line indicates synovial fluid neutrophils from a mouse with established arthritis, red line shows synovial fluid neutrophils from control mouse, and black line reveals staining of established arthritis using an isotype control. The arthritic synovial fluid contains a large population of Ly-6G positive neutrophils while this population was absent in the synovial fluid of a control mouse. Right panel quantitation of the number of Ly-6G positive cells in control and arthritic joints (control mice n=2, arthritic mice n = 2). Data are the meaniSEM P<0.05 versus control mice.

The switch panel at the right side of the machine controls the motors for the hydraulic pump, wheel spindle, cutting fluid, etc. and carries the main isolator and a large mushroomheaded stop button (12).
