Abstract
Abstract An actuating mechanism in which a source of fluid is directed against an end wall of a rigid body portion having an open cavity formed therein to create pressure waves of fluid which pass through the length of the cavity to the closed end thereof to cause a temperature rise at the closed end. This temperature rise is utilized to ignite an explosive device which, in turn, is utilized to accomplish work.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
222 words
An actuating mechanism comprising a first rigid body portion having a longitudinal axis having a cavity formed therein coaxially therewith, said cavity having an open end and a closed end, means to direct a source of fluid against a wall of said first body portion and towards said open end to create pressure waves of fluid which pass through the length of said cavity to said closed end to cause a temperature rise at said closed end, and means responsive to said temperature rise for accomplishing work, wherein said means to direct a source of fluid against the wall of said first rigid body portion includes a second rigid body portion fixedly connected to said first rigid body portion, said second rigid body portion having a longitudinal passage connected to said cavity coaxially therewith, said second rigid body portion having a transverse passage connected to said longitudinal passage and to said cavity and extending transverse to said longitudinal passage, said second rigid body portion having a radially outer surface, said longitudinal passage having a converging end portion having an outlet opening, said outlet opening facing said cavity open end coaxially therewith, said transverse passage having a radially inner inlet end disposed adjacent said cavity open end and having a radially outer outlet end having a vent opening extending through said exterior surface.
Claim 2
Dependent Claim
222 words
An actuating mechanism comprising a first rigid body portion having a longitudinal axis having a cavity formed therein coaxially therewith, said cavity having an open end and a closed end, means to direct a source of fluid against a wall of said first body portion and towards said open end to create pressure waves of fluid which pass through the length of said cavity to said closed end to cause a temperature rise at said closed end, and means responsive to said temperature rise for accomplishing work, wherein said means to direct a source of fluid against the wall of said first rigid body portion includes a second rigid body portion fixedly connected to said first rigid body portion, said second rigid body portion having a longitudinal passage connected to said cavity coaxially therewith, said second rigid body portion having a transverse passage connected to said longitudinal passage and to said cavity and extending transverse to said longitudinal passage, said second rigid body portion having a radially outer surface, said longitudinal passage having a converging end portion having an outlet opening, said outlet opening facing said cavity open end coaxially therewith, said transverse passage having a radially inner inlet end disposed adjacent said cavity open end and having a radially outer outlet end having a vent opening extending through said exterior surface.
Claim 3
Dependent Claim
100 words
The mechanism of claim 1 wherein said means for accomplishing work comprising an explosive charge in heat exchange relation with said closed end, said temperature rise causing said explosive charge to ignite, and wherein said actuating mechanism is a one-piece rigid housing arranged so that said first rigid body portion and said second rigid body portion are axially spaced portions thereof, and wherein said transverse passage is disposed substantially at right angles to said longitudinal passage, and wherein said first body portion has an axially outer end face having a recess receiving said explosive charge forming said cavity closed end.
