Abstract

Abstract An emergency beacon with automatic timer for starting transmission of distress signals, wherein a presetable automatic timer is coupled to the emergency beacon so as to start the signals after elapse of the preset time without requiring further action by a pilot, or other individual. Thus the timer may be preset for a time greater than the anticipated time called for in a flight plan, and upon expiration of that time the distress signals will be automatically transmitted. A warning device is provided that will give a warning signal prior to elapse of the preset time, whereby the time that the beacon will start transmission may be delayed. Moreover, manually actuated means are provided that may be actuated in an emergency for starting transmission of the distress signals.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 138 words
In an emergency beacon with automatic timer for starting transmission of distress signals: a. an emergency beacon with transmitter operable for radio broadcasting of international distress signals for use in aircraft rescue missions to warn control towers and aid in search flights and parties in locating aircraft in which the beacon and operable is carried; b. a presetable automatic timer coupled to the emergency beacon so that signals will start automatically after elapse of the preset time without further action by a pilot, or other individual, c. and in which a warning device is provided that will give an electrically actuated warning signal at a predetermined period of time prior to elapse of the preset time, whereby an opportunity will be afforded to delay the time at which the emergency beacon will start transmission of the distress signals.
Claim 2
Dependent Claim 138 words
In an emergency beacon with automatic timer for starting transmission of distress signals: a. an emergency beacon with transmitter operable for radio broadcasting of international distress signals for use in aircraft rescue missions to warn control towers and aid in search flights and parties in locating aircraft in which the beacon and operable is carried; b. a presetable automatic timer coupled to the emergency beacon so that signals will start automatically after elapse of the preset time without further action by a pilot, or other individual, c. and in which a warning device is provided that will give an electrically actuated warning signal at a predetermined period of time prior to elapse of the preset time, whereby an opportunity will be afforded to delay the time at which the emergency beacon will start transmission of the distress signals.
Claim 3
Dependent Claim 48 words
The emergency beacon with automatic timer for starting transmission of distress signals, as set forth in claim 1; d. and in which manually actuated means are provided that may be operated in an emergency for starting transmission of the distress signals prior to elapse of the preset time.
Claim 4
Dependent Claim 142 words
The emergency beacon with automatic timer for starting transmission of distress signals, as set forth in claim 1; d. and in which the automatic timer is coupled to the emergency beacon by an electrical circuit, the latter including a source of current; e. the automatic timer having time interval graduated means operable to indicate the preset time and being movable to an initial 0 position after elapse of the preset time; f. the automatic timer having a fixed contact and a movable switch arm forming part of the electrical circuit, the switch arm being movAble in unison with the time interval graduated means in a direction away from the fixed contact when setting the preset time, the switch arm being movable into closing relation with the fixed contact after elapse of the preset time, whereby transmission of the distress signals will start.
Claim 5
Dependent Claim 294 words
In an emergency beacon with automatic timer for starting transmission of distress signals: a. an emergency beacon with transmitter operable for radio broadcasting of international distress signals for use in aircraft rescue missions to warn control towers and aid in search flights and parties in locating aircraft in which the beacon is carried; b. a presetable automatic timer coupled to the emergency beacon and operable so that signals will start automatically after elapse of the preset time without further action by a pilot, or other individual; c. the automatic timer being coupled to the emergency beacon by an electrical circuit, the latter including a source of current; d. the automatic timer having time interval graduated means operable to indicate the preset time and being movable to an initial 0 position after elapse of the preset time; e. The automatic timer having a fixed contact and a movable switch arm forming part of the electrical circuit, the switch arm being movable in unison with the time interval graduated means in a direction away from the fixed contact when setting the preset time, the switch arm being movable into closing relation with the fixed contact after elapse of the preset time, whereby transmission of the distress signals will start; f. a second fixed contact provided on the automatic timer which is arranged ahead of the initial 0 position, and the switch arm is movable into engagement with this second fixed contact as it moves toward the initial 0 position; g. and a warning light electrically connected to the source of current and the second fixed contact so that the light will be illuminated when the switch arm engages with the second fixed contact, whereby a warning will be flashed that the preset time is approaching expiration.
