Abstract
Abstract The booster motors, each attached to and surrounding a centerbody, are mully connected to each other via one or more hollow manifold legs through which propulsive gases flow freely. At a predetermined time, the manifold cutter receives a signal activating the cutter to sever the manifold leg. Upon severance, the cut manifold leg still attached to the booster acts as a nozzle by venting residual propulsive gases and thereby propelling the booster away from the centerbody.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A manifold separation device for separating a booster from a centerbody at a predetermined time, said booster co-operating with a plurality of adjacent boosters to expedite the flight of said centerbody, said device comprising: a manifold plumbing assembly, said assembly being coupled between said booster and an adjacent booster to provide a continuous flow path for a suitable medium to flow from said booster to said adjacent booster; a timing means; a means for severing, said severing means being suitably coupled between said timing means and said plumbing assembly for receiving a signal from said timing means and severing said assembly in response to said signal; a niche suitably formed on said centerbody; and a force transfer means having a first end and a second end, said transfer means being fixedly attached at said first end to said booster and abutting at said second end into said niche such that upon the severance of said plumbing assembly, said transfer means slides off from said niche to effect the separation of said booster from said centerbody.
Claim 2
Dependent Claim
175 words
A manifold separation device for separating a booster from a centerbody at a predetermined time, said booster co-operating with a plurality of adjacent boosters to expedite the flight of said centerbody, said device comprising: a manifold plumbing assembly, said assembly being coupled between said booster and an adjacent booster to provide a continuous flow path for a suitable medium to flow from said booster to said adjacent booster; a timing means; a means for severing, said severing means being suitably coupled between said timing means and said plumbing assembly for receiving a signal from said timing means and severing said assembly in response to said signal; a niche suitably formed on said centerbody; and a force transfer means having a first end and a second end, said transfer means being fixedly attached at said first end to said booster and abutting at said second end into said niche such that upon the severance of said plumbing assembly, said transfer means slides off from said niche to effect the separation of said booster from said centerbody.
Claim 3
Dependent Claim
29 words
A separation device as set forth in claim 1, wherein said manifold assembly comprises a hollow manifold legs, said leg being coupled between said booster and said adjacent booster.
Claim 4
Dependent Claim
87 words
A separation device as set forth in claim 2, wherein said severing means comprises a plurality of buses, said buses being appropriately affixed to said centerbody and being coupled to said timing means to receive signals therefrom and further transmit the signals; a manifold cutter, said cutter being suitably mounted to cut said manifold leg upon activation; and a contacting means releasably coupled to said buses and being further coupled to said cutter to transmit the signals from said buses to said cutter to activate said cutter.
Claim 5
Dependent Claim
25 words
A separation device as set forth in claim 3, wherein said strut has a cavity therethrough and said contacting means is housed in said cavity.
Claim 6
Dependent Claim
130 words
A manifold separation device for separating a booster from a centerbody at a predetermined time, said device comprising: a hollow manifold leg, said leg flowably connecting said booster with an adjacent booster to permit unobstructed flowage of a medium through said leg and said boosters; a timing means; a means for severing, said severing means being coupled between said timing means and said manifold leg for receiving a signal from said timing means and severing said leg in response to the signal; and a strut, said strut being fixedly attached at one end to said booster and slidably abutting at opposing end said centerbody, said strut further being adapted for sliding off said centerbody upon the severance of said leg to effect the separation of said booster from said centerbody.
Claim 7
Dependent Claim
130 words
A manifold separation device for separating a booster from a centerbody at a predetermined time, said device comprising: a hollow manifold leg, said leg flowably connecting said booster with an adjacent booster to permit unobstructed flowage of a medium through said leg and said boosters; a timing means; a means for severing, said severing means being coupled between said timing means and said manifold leg for receiving a signal from said timing means and severing said leg in response to the signal; and a strut, said strut being fixedly attached at one end to said booster and slidably abutting at opposing end said centerbody, said strut further being adapted for sliding off said centerbody upon the severance of said leg to effect the separation of said booster from said centerbody.
