Abstract: Lubrication compositions comprising from about 80% to about 99.9% of a synthetic ester lubricant; and from about 0.1% to about 8% of a polyalkyl methacrylate mist suppressant. The synthetic ester lubricant may be an adipate ester lubricant, which may be a ditridecyl adipate, a phthalate ester lubricants, such as diisononyl phthalates and ditridecyl phthalates, or mixtures thereof. The compositions may also comprise a highly branched isoparaffinic polyalphaolefin lubricant. The lubricating compositions may also comprise one or more additives.

Abstract: A pressure pad has two sets of cells with a sensor pad positioned under the pad. During inflation, part of the flow goes to the sensor pad to exhaust and the rest fills the cells. Any change in patient position/weight causing a change in airflow in tube will alter the differential pressure measured at a pressure transducer. Based on this feedback a microprocessor directly controls the power level to the pump, thus adjusting the airflow to the cells to prevent bottoming or to rung at a minimum pressure. The pressure pad is segmented into a heel section, upper leg section, torso section, and a head section. The heel, head, and upper leg sections are maintained at a lower pressure, and the torso section at a higher pressure. A control module to control the flow in the segments is provided inside the pressure pad. The pressure pad can be an alternating or static pad.

Abstract: A support surface 10 includes a series of inflatable cells 30, 40 inflated alternately by a compressor 11. The cells 30, 40 are exhausted via an exhaust port 50 having a restrictor 60 of known diameter. A pressure transducer 70 measures the cell 30, 40 pressure. Some of the cells 30, 40 during their deflating/inflating cycle are exhausted through the exhaust port 50 and the cell pressure decay over a time is monitored. A microprocessor calculates the mathematical function related to the cell pressure decay with time, compares the value with compiled data and adjusts the output of the compressor accordingly. The sequence of exhausting via a port 50 is repeated at every inflation/deflation cycle and the pressure decay monitored and compared with the known data and the compressor output adjusted automatically to provide a new operating pressure. Therefore, any change in the person's position, e.g.

Abstract: A method of regulating the power generated in a nuclear power plant which includes the step of regulating the flow of helium through the reactor. To this end, the power plant includes a closed loop power generation circuit having at least one compressor and a recirculation circuit whereby helium can be recirculated around the compressor. By regulating the flow of helium around the recirculation circuit using suitable valves the flow of helium through the reactor and hence the power generated can be regulated. The plant includes a helium inventory control system whereby the inventory of helium in the power generation circuit can be varied thereby varying the power generated in the circuit.

Abstract: A pressure pad (1) has two sets of cells (11, 12) with a sensor pad (8) positioned under the pad (1). During inflation, part of the low goes to the sensor pad (8) to exhaust and the rest fills the cells (11 or 12). Any change in patient position/weight causing a change in airflow in tube (10) will alter the differential pressure measured at the pressure transducer (16). Based on this feedback the microprocessor directly controls the power level to the pump (6) thus adjusting the airflow to the cells to prevent bottoming or to rung at a minimum pressure. The pressure pad (1) is segmented into a heel section, upper leg section, torso section, and a head section. The heel, head and upper leg sections are maintained at a lower pressure P1 and the torso section at a higher pressure P2. A control module (50) to control the flow in the segments is provided inside the pressure pad (1). The pressure pad (1) can be an alternating or static pad.

Abstract: A pressure control system for controlling pressure in a fluid system includes a compressor for producing pressurized fluid coupled to a rotor valve, a pressure controller, and a visual low-pressure indicator. A manifold directly supports the valve and has, integrated within, the pressure controller, the low-pressure indicator, and the output connections. The pressure controller includes a plunger and a spring communicating with the fluid system. The pressurized fluid acts against the plunger and the spring, and excess fluid is discharged when pressure exceeds a predetermined value. The low-pressure indicator includes a diaphragm movable away from a transparent window, providing a visual indication of the pressure within the system. The manifold assembly provides connectors for supplying fluid to the system.
