6130-01-283-0103 6130012830103 012830103 is a component which converts available alternating current or direct current electrical power into a form required to operate another component or set. the item may consist of a combination of an invertor, vibrator; vibrator, interrupter; vibrator, self-rectifying; invertor, power, static; with a transformer and rectifier(s) employing electron tubes, semiconductor diode or metallic (dry disc) type components, or the synchronized secondary contact(s) of a vibrator, self-rectifying; or may consist of electron tubes, semiconductor diode or metallic (dry disc) type rectifiers and capacitors in transformerless (alternating current-direct current type) circuits which may be of the voltage-multiplier type. the item may incorporate a filter, direct current power and provisions for regulation of input and/or output voltage. the item may have special input, output, control or other facilities for applications in specialized environments such as medical, dental or other operations. excludes battery chargers and rotating machinery types of items, such as motor generators and dynamotors.

1660-01-364-0512 1660013640512 013640512 is a device consisting of a facepiece which partially covers the face, having a breathing tube and a coupling for connecting to a regulated supply of oxygen. the device may be of the rebreathing type or of the demand type and may be used for rescue operation or to supply the wearer with oxygen when flying at high altitudes. it may include regulating device(s) but does not include oxygen cylinder(s). excludes mask, oronasal.

5925-12-347-8489 5925123478489 123478489 is a device with means other than fuses for automatically opening the circuit in which it is installed when the current varies from the predetermined value for which the device is set. may include provisions for manual operation. at least one set of contacts must be in series with the actuating element(s). a combination of semiconductor and passive devices may be used in lieu of contacts. for automatically operated items in which the actuating (tripping) element and contacts are not in series, see relay (as modified). for items which are operated both manually and automatically but the actuating elements and contact are not in series, see relay-switch. excludes circuit breaker box and magneto "breaker" assemblies. see also switch (as modified); and controller.
