Abstract
Abstract A method for transmitting detonation at 90° and other sharp angles using special end tips. Cylindrical end tip cups are loaded in a shaped die under sufficient pressure to change the shape to a square or rectilinear cross-section. The flat side of one end tip is placed adjacent the end of a second end tip to transmit detonation at a sharp angle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
97 words
A method for transmitting detonations at a sharp angle in either direction comprising the step of shaping a donor and an acceptor end tip to a configuration such that when placed in contact with each other said donor and acceptor end tips are in planar contact, said shaping step being accomplished by: (a) placing a cylindrical end tip cup in a die having a cavity of said configuration; (b) loading an explosive into said cup; and (c) applying a force to said explosive sufficient to deform the walls of said cup against the walls of said die.
Claim 2
Independent Claim
97 words
A method for transmitting detonations at a sharp angle in either direction comprising the step of shaping a donor and an acceptor end tip to a configuration such that when placed in contact with each other said donor and acceptor end tips are in planar contact, said shaping step being accomplished by: (a) placing a cylindrical end tip cup in a die having a cavity of said configuration; (b) loading an explosive into said cup; and (c) applying a force to said explosive sufficient to deform the walls of said cup against the walls of said die.
Claim 3
Independent Claim
103 words
A method for transmitting detonations at a sharp angle in either direction comprising the step of shaping a donor and an acceptor end tip to a configuration such that when placed adjacent each other said donor and acceptor end tips have faces parallel to each other to transmit detonations across a gap, said shaping step being accomplished by: (a) placing a cylindrical end tip cup in a die having a cavity of said configuration; (b) loading an explosive into said cup; and (c) applying a force to said explosive sufficient to deform the walls of said cup against the walls of said die.
Claim 4
Independent Claim
103 words
A method for transmitting detonations at a sharp angle in either direction comprising the step of shaping a donor and an acceptor end tip to a configuration such that when placed adjacent each other said donor and acceptor end tips have faces parallel to each other to transmit detonations across a gap, said shaping step being accomplished by: (a) placing a cylindrical end tip cup in a die having a cavity of said configuration; (b) loading an explosive into said cup; and (c) applying a force to said explosive sufficient to deform the walls of said cup against the walls of said die.
Claim 5
Independent Claim
36 words
A method for transmitting detonations as recited in claims 1 and 2 wherein the step of applying said force comprises ramming said explosive with a ram which is equal to the inside diameter of said cup.
