9340-00-476-1330 9340004761330 004761330 is a transparent item of a predetermined size that permits unobstructed and undistorted view of a desired area. it may include a frame, have reference markings, grid lines and may be heat strengthened and/or tinted. it is generally used where safety, security, and/or the restriction of foreign matter are required, such as the visual examination of the inside of pressurized tanks, liquid sights, controlled liquid flow, and inspection of equipment enclosed in a housing. see window (as modified); scale, cathode ray tube; scale, plotting; window, metal; window, wood; and window panel, aircraft.

6685-22-257-8105 6685222578105 222578105 is an instrument designed to measure air, gas, fluid, and vapor pressure by means of an internal pressure sensitive element (bellows, bourdon tube, transducer/transmitter and the like) which transmits energy, by direct linkage, to the indicating pointer of a scale or a digital display, calibrated in units of pressure.it may include a temperature equivalent scale.for items that do not have an internal pressure sensitive element see indicator, pressure.

5905-01-257-8105 5905012578105 012578105 is a resistor whose ohmic value cannot be adjusted or varied. the resistance element consists of either a thin layer of conductive material, containing either binders or insulating materials, deposited on an insulated form; or an alloy of metal and ceramic materials, usually fused to an insulated form. opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the resistor. see also attenuator, fixed and resistor, fixed, composition. excludes carbon composition type resistors.

5950-14-257-8105 5950142578105 142578105 is an item consisting of a partial turn as one or more turns of wire or other conductive material which constitutes one continuous untapped winding. it may be wound or formed in other than a circular manner and may be self-supporting, requiring no coil form. it is specifically designed to furnish inductive reactance in a circuit carrying radio frequency current ranging from 20 kilohertz (kilocycles) and above. it may include tuning devices, integral resistors and capacitors; however, excludes filter (as modified). the coil has only two electrical terminals. for items having tapped winding or more than one winding - see transformer, radio frequency. for coils wound on resistors, which are designed to be inserted in the circuit of a radio frequency stage to suppress high frequency parasitic oscillations, see suppressor, parasitic.
