Abstract
Abstract A process for the production of explosive devices surrounded by a case wherein an explosive charge is placed in a matrix mold and a pressing tool is moved in one direction of the mold to apply a force to one of mutually opposite end portions of the explosive device formed by the pressing operation. Subsequently, the explosive device is placed in a case having an open end with the other mutually opposite end portion proximate to the open end. A pressing tool is then moved to apply a force to the other mutually opposite end portion of the explosive device such that in the two pressing operations, a pressing tool is effective on the mutually opposite end portions to provide the explosive device with a uniform density. The process also includes the press molding of a detonation inhibiting barrier within the case prior to placing the explosive within the case and subsequently sealing the open end of the case with a sealing member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
159 words
Process for the production of explosive devices surrounded by a case comprising the steps of placing an explosive charge in a matrix mold, moving a pressing tool in a first direction within the mold to apply a force to the explosive charge to compress the charge and form an explosive device of a predetermined shape with mutually opposite end portions, the pressing tool during the movement thereof applying the force to one of the mutually opposite end portions, placing the explosive device within a case having an open end such that the other mutually opposite end portion of the explosive device is arranged proximate thereto, and moving a pressing tool to apply a force to the other mutually opposite end portion of the explosive body within the case such that in the two pressing operations, a pressing tool is effective on the mutually opposite end portions of the explosive device to provide the explosive device with a uniform density.
Claim 2
Dependent Claim
159 words
Process for the production of explosive devices surrounded by a case comprising the steps of placing an explosive charge in a matrix mold, moving a pressing tool in a first direction within the mold to apply a force to the explosive charge to compress the charge and form an explosive device of a predetermined shape with mutually opposite end portions, the pressing tool during the movement thereof applying the force to one of the mutually opposite end portions, placing the explosive device within a case having an open end such that the other mutually opposite end portion of the explosive device is arranged proximate thereto, and moving a pressing tool to apply a force to the other mutually opposite end portion of the explosive body within the case such that in the two pressing operations, a pressing tool is effective on the mutually opposite end portions of the explosive device to provide the explosive device with a uniform density.
Claim 3
Dependent Claim
34 words
A process according to claim 1, further comprising the step of press molding a detonation inhibiting barrier surrounded by an annular charge within the case prior To placing the explosive body within the case.
Claim 4
Dependent Claim
47 words
A process according to claim 2, wherein the case has an ignition opening in the end opposite the open end thereof and further comprising the step of extending a centering pin through the ignition opening of the case and centering the inhibiting barrier with the centering pin.
Claim 5
Dependent Claim
59 words
A process according to claim 1, further comprising the step of placing a sealing member in the case after placing the explosive device within the case and then moving the pressing tool against the sealing member to apply the force to the other mutually opposite end portion of the explosive device and seal the open end of the case.
Claim 6
Dependent Claim
48 words
A process according to claim 1, wherein the matrix mold is a tubular mold having one end portion closed by a conical member extending into the mold, and moving the pressing tool through the open end portion of the mold in the direction of the closed end portion.
Claim 7
Dependent Claim
73 words
A process according to claim 5, wherein the pressing tool has a flat end face and moving the flat end face into contact with the one mutually opposite end portion of the explosive device to provide the one mutually opposite end portion of the explosive device with a substantially flat end surface, the other mutually opposite end portion being provided with an end surface conforming to the conical member extending into the mold.
Claim 8
Dependent Claim
45 words
A process according to claim 6, wherein the pressing tool for movement into the case has a conical end surface conforming to the conical end surface of the explosive device and moving the conical end surface toward the conical end surface of the explosive device.
Claim 9
Dependent Claim
72 words
A process according to claim 7, further comprising the step of placing a conical sealing member conforming to the conical end surface of the explosive device in the case after placing the explosive device in the case and moving the pressing tool with the conical end surface against the sealing member to apply the force to the explosive device and to seal the open end of the case with the sealing member.
Claim 10
Dependent Claim
31 words
A process according to claim 8, further comprising prior to placing the explosive device in the case, press molding a detonation inhibiting barrier surrounded by an annular charge within the case.
Claim 11
Dependent Claim
47 words
A process according to claim 9, wherein the case has an iginition opening in the end opposite the open end thereof and further comprising the step of extending a centering pin through the ignition opening of the case and centering the inhibiting barrier with the centering pin.
Claim 12
Dependent Claim
23 words
A process according to claim 10, further comprising disposing the case within a mold prior to placing the explosive device within the case.
Claim 13
Dependent Claim
23 words
A process according to claim 1, further comprising disposing the case within a mold prior to placing the explosive device within the case.
Claim 14
Dependent Claim
20 words
A process according to claim 1, comprising providing the explosive charge with a high proportion by weight of high explosive.
Claim 15
Dependent Claim
25 words
A process according to claim 1, comprising providing the explosive charge with a high proportion of high explosive in excess of 95 percent by weight.
