摘要: A data display device has a manual input keyboard device that is infinitely adjustable with respect to its supporting surface between predetermined limits. The angular displacement mechanism that provides this adjustment is made up of a fixed arbor attached to the keyboard device and a rotating arbor attached to a foot. The arbors are axially aligned and rotatably connected together by a clutch coil spring. A manually operable push button mechanism on the keyboard device is linked to the tang of the coil spring so that when depressed, the tang is moved in a direction to unwind the coil spring, thereby permitting the locating arbor to rotate with respect to the fixed arbor, moving the foot away from the keyboard device. A tilt torsion spring is anchored to the movable arbor and connected to the keyboard device to cause the rotatable arbor to rotate when the push button is actuated thus moving the foot with respect to the keyboard device. Releasing the push button permits stopping the movement of the foot at any desired position.

摘要: An enclosed, electronic system has a plurality of lower power-dissipating electronic components mounted on a chassis. The components are positioned adjacent each other to form low volume fluid ducts therebetween. A low volume fluid duct is formed between one side of the plurality and one end enclosure of the system. At least one higher power-dissipating electronc component is also mounted on the chassis, forming a high volume fluid duct between one of its sides and one side of the last of the lower power-dissipating electronic components, and a high volume fluid duct also formed between the other side of the higher power-dissipating electronic component and the other end enclosure. Air is caused to blow through the low volume fluid duct and then to be exhausted through the high volume fluid ducts. The rate of air flow through the high volume ducts is one half of the minimum required to cool the higher power-dissipating component. The rate of air flow through the low volume fluid ducts is at least one half of that required to cool each of the lower power-dissipating electronic components. By exhausting the cooling air from the low volume fluid channels through the high volume fluid ducts, the air flow required is less than the total required for the low volume fluid ducts plus the high volume fluid ducts.
