Claim 2

A two-part detonating assembly comprising: a. a first detonating unit comprising:

Claim 3

a first inner casing defining a first-stage detonating chamber,

Claim 4

a first inner casing defining a first-stage detonating chamber,

Claim 5

an outer second casing enclosing said first casing and defining a main second-stage detonating chamber,

Claim 6

an outer second casing enclosing said first casing and defining a main second-stage detonating chamber,

Claim 7

The apparatus as recited in claim 1, wherein said squib means is mounted within said inner casing.

Claim 8

The apparatus as recited in claim 1, wherein said outer casing is an elongate tubular member, and said inner casing is also an elongate tubular member located generally concentrically in said outer casing.

Claim 9

said inner casing having opening means interconnecting said first-stage and second-stage detonating chambers,

Claim 10

said inner casing having opening means interconnecting said first-stage and second-stage detonating chambers,

Claim 11

squib means arranged relative to said first casing so that upon detonation its detonating force is directed to cause detonation in said first-stage chamber,

Claim 12

squib means arranged relative to said first casing so that upon detonation its detonating force is directed to cause detonation in said first-stage chamber,

Claim 13

The apparatus as recited in claim 1, wherein said second unit comprises syringe means with an injection needle by which said second explosive mix component is inserted into said first unit.

Claim 14

The apparatus as recited in claim 1, wherein said first explosive mix component comprises hydrazine and diethylenediamine, and said second explosive mix component comprises nitromethane.

Claim 15

said inner and outer casing so arranged that a detonating force from said first-stage chamber is directed to cause detonation in said second chamber, and

Claim 16

said inner and outer casing so arranged that a detonating force from said first-stage chamber is directed to cause detonation in said second chamber, and

Claim 17

a first explosIve mix component located in said first detonating unit, b. a second unit containing a second liquid explosive mix component to be combined with said first mix component to form a liquid explosive mixture in said first unit, and c. transfer means associated with at least one of said units to transfer said second liquid component from the second unit into the first unit to be mixed with the first explosive mix component to form the liquid explosive mixture, whereby the explosive mixture is able to pass through said opening means so that said explosive mixture is located in both the first and second-stage chambers.

Claim 18

a first explosIve mix component located in said first detonating unit, b. a second unit containing a second liquid explosive mix component to be combined with said first mix component to form a liquid explosive mixture in said first unit, and c. transfer means associated with at least one of said units to transfer said second liquid component from the second unit into the first unit to be mixed with the first explosive mix component to form the liquid explosive mixture, whereby the explosive mixture is able to pass through said opening means so that said explosive mixture is located in both the first and second-stage chambers.

Claim 19

A field mix detonator, comprising: a. a first inner casing defining a first-stage detonating chamber, b. an outer second casing enclosing said first casing and defining a main second-stage detonating chamber, c. said inner casing having opening means interconnecting said first-stage and second-stage detonating chambers, d. squib means arranged relative to said first casing so that upon detonation its detonating force is directed to cause detonation in said first-stage chamber, e. said inner and outer casing so arranged that a detonating force from said first-stage chamber is directed to cause detonation in said second chamber, and f. said unit being adapted to contain a first explosive mix component, g. said unit having entry means by which a second explosive mix component can be introduced into said detonator to form with said first mix component a liquid explosive mixture which because of said opening means can occupy both the first and second chambers to provide detonating charges in each of said chambers.

Claim 20

A field mix detonator, comprising: a. a first inner casing defining a first-stage detonating chamber, b. an outer second casing enclosing said first casing and defining a main second-stage detonating chamber, c. said inner casing having opening means interconnecting said first-stage and second-stage detonating chambers, d. squib means arranged relative to said first casing so that upon detonation its detonating force is directed to cause detonation in said first-stage chamber, e. said inner and outer casing so arranged that a detonating force from said first-stage chamber is directed to cause detonation in said second chamber, and f. said unit being adapted to contain a first explosive mix component, g. said unit having entry means by which a second explosive mix component can be introduced into said detonator to form with said first mix component a liquid explosive mixture which because of said opening means can occupy both the first and second chambers to provide detonating charges in each of said chambers.

Claim 21

The detonator as recited in claim 6, wherein said squib means is mounted within said inner casing.

Claim 22

The detonator as recited in claim 6, wherein said outer casing is an elongate tubular member, and said inner casing is also an elongate tubular member located generally concentrically in said outer casing.
