Computer systems and associated methods for cooling computer components are disclosed herein. One embodiment of a computer system includes a computer cabinet having an air inlet spaced apart from an air outlet. The computer system also includes heat exchangers positioned in the computer cabinet, and a heat removal system in fluid communication with the heat exchangers. The computer system additionally includes at least one sensor for monitoring heat transfer between the computer cabinet and the room. The computer system further includes a control system operatively coupled to the at least one sensor, the control system including a computer-readable medium holding instructions for determining whether heat transfer between the computer cabinet and the room is balanced based on information from the sensor, and if not, adjusting a parameter to balance the heat transfer.

A cable following apparatus especially suitable for use in replacing existing underground cable by reaming around and along the length of the cable is disclosed herein. This apparatus includes a main body or cable follower which is interconnected with the cable to be replaced for slidable movement along the latter. In order to accomplish this, the apparatus includes a specifically designed mechanism for releasably gripping the cable at least at one end preferably two points along the cable in a specifically controlled fashion. At the same time, the apparatus provide means for reaming around the cable, preferably by means of one or more floor jets. Once the soil surrounding the cable has been loosened using this apparatus, the cable can be easily pulled out of the ground. A replacement cable can be attached to the existing cable and therefore pulled into place.

Systems and methods for cooling computer components in large computer systems are disclosed herein. In one embodiment, a computer system configured in accordance with aspects of the invention can include a computer module positioned in a chassis, and an air mover configured to move air through the chassis and past the computer module. The computer system can further include a pressure sensor operably coupled to the air mover. If the pressure sensor determines that the difference between a first air pressure inside the chassis and a second air pressure outside the chassis is less than a preselected pressure, the air mover can increase the flow of air through the chassis and past the computer module.

Systems and methods for operatively connecting processor banks in large computer systems are disclosed herein. In one embodiment, a computer system includes a first bank of processors, a second bank of processors spaced apart from the first bank of processors, and a connector assembly configured to operatively connect at least a portion of the first bank of processors to at least a portion of the second bank of processors. The connector assembly can include a first connector unit having a plurality of first connector sets and a second connector unit having a plurality of corresponding second connector sets. At least one of the first and second connector units is movable relative to the other one of the first and second connector units to at least approximately concurrently engage the plurality of first connector sets with the plurality of corresponding second connector sets.
摘要:
A jet assisted drill system which uses a high pressure intensifier, positioned in a down hole drill assembly. Drill fluid from a drill stem is directed into the drill assembly, and in one mode this drill fluid is passed through the pressure intensifier to cause a piston assembly of the intensifier to reciprocate, with high pressure pistons of the piston assembly delivering high pressure drill fluid to a discharge jet in the drill bit assembly. The lower pressure fluid which drives the low pressure pistons is discharged into a downstream annular passageway and to the drill bit assembly. In a by-pass mode, a selector valve directs drill fluid from an upstream main passageway portion directly to a downstream main passageway portion to pass out the drill bit assembly. This flushes out debris which is carried upwardly out of the drill hole. There is a control valve to operate the piston assembly and a trigger valve operated by the piston assembly to direct fluids selectively to the control valve.

A cable following apparatus especially suitable for replacing existing underground cable is disclosed herein. This apparatus includes a tubular main body disposed around and movable along a particular cable in a forward direction while an arrangement of water jets are used to cut through the soil surrounding the cable in front of the forwardly moving main body. At the same time, a high pressure stream of air or similar gas is directed into a circumferential area between the front end of the main body and the cable in a way which is intended to prevent particulate material from passing therebetween and damaging or otherwise disrupting operation of the apparatus.
