Abstract
Abstract An assembly comprising a plurality of separable sections releasably interconnected. A control device is provided for releasing the separable sections in response to a predetermined signal, and a magnetic separation means is operatively associated with the separable sections for exerting a separation force therebetween upon release of the sections.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
Apparatus including two separable, independent sections, comprising: first and exclusive means for rigidly holding the sections together; second means for releasing the first means at a desired time; and magnetic separation means interposed between the two sections for producing a magnetic repulsion force between the two sections which is effective to separate them upon release of the second means.
Claim 2
Dependent Claim
59 words
Apparatus including two separable, independent sections, comprising: first and exclusive means for rigidly holding the sections together; second means for releasing the first means at a desired time; and magnetic separation means interposed between the two sections for producing a magnetic repulsion force between the two sections which is effective to separate them upon release of the second means.
Claim 3
Dependent Claim
17 words
Apparatus as claimed in claim 1 wherein the two separable sections constitute structure on a space vehicle.
Claim 4
Dependent Claim
68 words
Apparatus as claimed in claim 1 wherein the magnetic separation means includes at least two magnets placed side by side with their like poles adjacent one another, with one of said magnets being affixed to a first section and a second magnet being affixed to the other section, and further including mechanical means restraining relative movement between the two sections to linear movement which separates the two sections.
Claim 5
Dependent Claim
57 words
Apparatus as claimed in claim 1 wherein the magnetic separation means includes at least two magnets, with one of said magnets being affixed to a first section and a second one of said magnets being affixed to the other section, and at least one set of like poles of two magnets being adjacent and opposite one another.
Claim 6
Dependent Claim
17 words
Apparatus as claimed in claim 4 wherein at least one of said magnets is a permanent magnet.
Claim 7
Dependent Claim
38 words
Apparatus as claimed in claim 1 wherein the first means for rigidly holding the sections together comprises an explosive bolt and the second means comprises means for generating an electromotive force to detonate the expLosive in said bolt.
Claim 8
Dependent Claim
69 words
Apparatus as claimed in claim 6 wherein the means for generating an electromotive force constitutes a source of electromotive force in series with a normally open switch which is closable by action of a control device which is responsive to temperature, altitude, pressure, elapsed time, proximity, acceleration, force, or orientation, and wherein the first means for rigidly holding the sections together comprises an explosive bolt connected between the sections.
Claim 9
Independent Claim
119 words
The method of separating a first section from a second section on a space vehicle at a desired time, comprising the steps of: placing at least one pair of magnets adjacent one another between the first and second sections, with at least one set of like poles of the pair of magnets placed opposite one another to establish a repelling force between the pair of magnets which acts in a direction tending to separate the two sections; establishing a holding force for holding the two sections together in opposition to the repelling force; and releasing the holding force at a desired time to permit the repelling force to separate the two magnets and thereby to separate the two sections.
Claim 10
Independent Claim
119 words
The method of separating a first section from a second section on a space vehicle at a desired time, comprising the steps of: placing at least one pair of magnets adjacent one another between the first and second sections, with at least one set of like poles of the pair of magnets placed opposite one another to establish a repelling force between the pair of magnets which acts in a direction tending to separate the two sections; establishing a holding force for holding the two sections together in opposition to the repelling force; and releasing the holding force at a desired time to permit the repelling force to separate the two magnets and thereby to separate the two sections.
