Abstract: A compressor includes a casing, a compression mechanism, a drive shaft, a main frame, a motor, a flow path forming member, and a temperature measuring mechanism. The casing stores lubricating oil in its bottom portion. The main frame has the compression mechanism placed on it and supports the drive shaft in such a way that the drive shaft may freely rotate. The flow path forming member forms an oil flow path at a space adjacent an inner peripheral surface of the casing. The oil flow path carries a flow of lubricating oil, which lubricates sliding portions including the compression mechanism and the drive shaft. The temperature measuring mechanism is disposed outside the casing. The temperature measuring mechanism measures the temperature of a section of an outer peripheral surface of the casing adjacent the oil flow path.

Abstract: Complex on-chip interconnect fabrics, particularly those that include point-to-point interconnects and coherent routing networks, can present significant challenges for conventional trace techniques that may be applied in an effort to efficiently provide an external debugger with visibility into on-chip interconnect transactions. Embodiments described herein generate and supply separate in-circuit-trace messages including address messages and data messages, which are sent out (i.e., off-chip) to external debug tools generally without delay and coincident with the distinct, but related, trace events within address and data paths of the interconnect fabric. These separate message instances embed appropriate tag and mark values to allow the message instances to be post-processed and correlated by the external debug tools so as to reconstruct the transaction information for operations performed in the on-chip interconnect.

Abstract: Systems and methods for specifying one or more operational parameters for a pumping system are disclosed. A first suction pressure loss profile for a first pump in a pumping system is determined. A second suction pressure loss profile for a second pump in the pumping system is determined. The first suction pressure loss profile is compared with the second suction pressure loss profile. One or more operational parameters are specified based, at least in part, on the comparison.

Abstract: Disclosed is a variable capacity type rotary compressor (1), a cooling apparatus having the same, and an operation method thereof, wherein in the variable capacity type rotary compressor (1) and the cooling apparatus having the same, a discharge pressure to be supplied to a rear side of a second vane (430) disposed in the compressor (1) is supplied after being higher than a reference pressure, so that the compressor (1) can be switched from a saving mode into a power mode, whereby the second vane (430) can be press-contacted with a second rolling piston (420) with fast and accurately moving without vibration, resulting in preventing beforehand noise occurrence or efficiency degradation due to the vibration of the second vane (430) when the compressor (1) or the cooling apparatus having the compressor (1) is operated in the power mode.

Abstract: A process comprises the phases of: activating a pusher, which exerts a push force on a plunger of a syringe containing the infusion liquid; measuring the push force by means of a load cell; comparing the push force with a maximum threshold; halting the pusher when the maximum threshold is exceeded; after a predetermined pause, restarting the pusher and emitting a consent signal indicating correct loading of the syringe if, within a certain time from the restart, the push force again exceeds the maximum threshold. The infusion device serves to inject an anticoagulant into an extracorporeal blood circuit. The control process guarantees against loss of infusion due to an incorrect initial loading of the syringe.

Abstract: Accumulator device for a hydraulic installation which includes an interior membrane, the membrane forming a fluid-accumulation cavity. It is characterised in that the membrane includes a fold which forms two sections, a first section from the wall of the cylindrical body to the fold and a second section from the fold to the moving support element, with the fold zone moving as the moving support element moves. It allows sufficient volumes of water accumulation to space apart the starting and stopping of the electrically-driven pump, but with small diameters of the membrane's moving support element.

Abstract: A pressurized air system controls air pressure in air reservoirs that deliver compressed air to air-actuated components in a vehicle. An air compressor supplies compressed air to air reservoirs which deliver compressed air to air-actuated components. A control system measures the air pressure in the air reservoirs by using at least one electric switch. Each switch is connected to an air reservoir and generates an electric signal to an electrically controlled valve indicative of the measured air pressure in the corresponding air reservoir. The electrically controlled valve is connected to an air compressor. The electrically controlled valve moves between a first position causing the air compressor to supply compressed air to the air reservoirs and a second position causing the air compressor to stop supplying compressed air to the air reservoirs responsive to the received electronic signal.

The electrically controlled valve moves between a first position causing the air compressor to compress air and to supply compressed air to the air reservoirs and a second position causing the air compressor to stop compressing air, responsive to the received electronic signal.

Abstract: A water pressure control system in which the pressurizing pump is turned on only in response to low pressure but is turned off only in response to low water flow rates. Water flow is detected with a magnetic switch displaced by water movement. After the pump is turned on, it can not be turned off for ten seconds, to smooth operation. When the system is first activated, the pump is turned on for sixty seconds, without regard to the other control functions, to guarantee priming of the pump.

Abstract: To protect the pump of a whirlpool bath against running dry and against blockage at the inlet, a pressure (or flow) sensor 14 senses pump pressure and generates a signal to keep a switch S2 in the pump motor electrical supply circuit closed. If the pressure signal ceases owing to blockage or running dry, the switch S2 opens. A manual override button 15 is held ON to close switches S1a and S1b in the power circuit for start-up. The sensor 14 and manual button 15 are preferably air pressure devices. Switch S1a is preferably an air-signal-operated latching switch whereby with the pump operating, the button 15 can be operated to switch the pump off. Relays RLA 1 and 2 may be used in conjunction with the electrical switches. A bleed hole may be provided between the button 15 and switch S1b to limit the period of time for which the motor could be run, with the bath empty, by prolonged inadvertent actuation of the button 15.

Abstract: An electroresponsive device is energized to actuate an internal combustion engine throttle for switching the engine from idle to a higher speed. The engine drives a hydraulic pump that supplies fluid through a control valve, then a cylinder lock, for driving hydraulic work cylinders. A first switch responds to a low pressure level being exceeded, due to fluid being directed by the control valve to an actuator, to increase engine speed, thereby making the pump pressure higher. A second switch responds to the higher pressure to continue the increased engine speed. When the control valve is restored to neutral position, the hydraulic fluid bypasses through the control valve directly to a sump and the second switch responds to the lower pressure by allowing the engine to go idle speed. A time delay device is provided for disabling the first switch during the time that pressure is dropping from the higher level to below the lower level.

Abstract: Disclosed herein is a protection system for a well pump in which a normal pressure switch is provided in series between this switch and the submerged motor and pump with a low pressure switch which has connected in parallel thereto a timing device which can in turn transmit directions to the pump, motor, control and starter to assure that a pump is not allowed to continue to run when there is no water in the well thereby causing a burnout. Check valves and a bleeder line are carefully positioned in this series to assure that the reading given by the low pressure switch, the normal pressure switch are real readings and that the pump is not inadvertenantly allowed to run due to incorrect signals derived therefrom.
