Protection positive return

A positive return of revenue only occurs after the drug has been approved by regulatory authorities for marketing. The overall profitabihty of a drug is the difference between the positive returns and the negative expenses within the patent period of 20 years. After that period, if the patent is not extended, there is no further protection on the intellectual rights for the drug. 

With forced stray current drainage, the current is returned from the pipeline to the rails by means of a grid-fed rectifier. The transformer-rectifier is connected into the stray current return conductor, the negative pole is connected with the installation to be protected and the positive pole is connected to the rails or the negative side of the bus bar in the transformer substation. 

All respiratory protective systems should be stored in clean, dry conditions but be readily accessible. They should be inspected and cleaned regularly, with particular attention to facepiece seals, nonreturn valves, harnesses etc. Issue on a personal basis is essential for regular use otherwise the equipment should be returned to a central position. Records are required of location, date of issue, estimated duration of use of canisters etc. 

Figure 10.7 illustrates the use of an external power supply to provide the cathodic polarisation of the structure. The circuit comprises the power source, an auxiliary or impressed current electrode, the corrosive solution, and the structure to be protected. The power source drives positive current from the impressed current electrode through the corrosive solution and onto the structure. The structure is thereby cathodically polarised (its potential is lowered) and the positive current returns through the circuit to the power supply. Thus to achieve cathodic protection the impressed current electrode and the structure must be in both electrolytic and electronic contact. 

Drainage (electric drainage) (a) flow of positive current through the soil or the electrolyte solution from the cathodically protected structure to the groundbed of the impressed current system, or (b) protection of an immersed structure from electrochemical corrosion by making an electrical connection between the structure and the negative return circuit (rail, feeder, busbar) of a d.c. electric traction system. 

The prime objective of a business is provide a positive economic return to the owners. Therefore the economic interest of the owners should be protected for long and short range survival without fear of a potential loss of earnings. 

Errors that resulted in the component being unavailable when needed—For example, equipment not restored to full operability following maintenance, testing, or inspection. Valves left closed, actuation or protective systems not reconnected, slip-blinds left in the line, or failing to return pump selector switches to the standby auto-start position are common examples. 

Benzoylacetone. Return the condenser (protected by the calcium chloride guard-tube) to the reflux position, surround the flask with ice and introduce 200 ml (2 mol) of pure, dry ethyl acetate (Section 4.1.24, p. 409). Start the stirrer and add 60 g (58 ml, 0.5 mol) of acetophenone from the dropping funnel the reaction commences with the separation of the sodium salt of... 

You can t be happy in retirement if you walk away from your children or grandchildren. Rather, you should take a positive view and build better relationships with adult children while simultaneously protecting your own freedom. Provide your family with the required support (financial or otherwise), but don t neglect other members of your support circle. Your adult children may require more from you than they are currently in a position to return. Things may change later and, when you need it, their support will be there. 

Retraction systems automatically withdraw the furnace camera several feet back from the firebox if the systems sense loss of either water, air coolant, or high lens tube temperature. This gives the lens additional protection from the heated air that would blow against the lens if fans stopped and negative pressure changed to positive pressure. The retraction system is often air-operated, using an air-reserve tank as a purely pneumatic system component. This makes it totally independent of electricity. On loss of air pressure, water coolant, or high lens tube temperature, a solenoid valve opens and activates a rodless cylinder to withdraw the lens from harms way. The system will not return the camera to its inserted position until the problem is corrected.
