Abstract
Abstract Apparatus for the storage of radio-active objects, such as, for example, radio-active needles or the like, comprising a cylindrical drum mounted for rotation about its axis within a cylindrical casing, a first plurality (m) of axially spaced tiers of radially directed cavities formed in said drum so as to join a second plurality (n) of radially spaced apart columns of cavities, an elongated opening formed in the casing, means for rotatably displacing the drum so as successively to bring successive cavity columns opposite said opening and a first plurality (m) of individual closure means associated with said opening and respectively adapted to close the cavities otherwise exposed by the opening.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
Apparatus for storing radioactive objects comprising: a. a cylindrical lead drum coaxially mounted inside a cylindrical casing for rotation about the common axis of the drum and casing; b. the casing having an axially directed slot exposing the drum; c. the drum containing m X n radially directed cylindrical cavities arranged in m axially spaced tiers and n radially spaced-apart columns; d. means for rotating the drum to selected angular positions for bringing respective ones of the cavities into alignment with the slot in the casing; and e. a plurality of axially spaced individual closure members on the casing adjacent the slot aligned with the m axially spaced tiers for closing the slot, but individually openable to provide an access to the drum aligned with a selected one of the tiers.
Claim 2
Dependent Claim
131 words

Claim 3
Dependent Claim
41 words
Apparatus according to claim 1 including settable selector means for identifying the cavity of interest, and a drive motor responsive to the setting of the selector means for rotating the drum until the cavity of interest is aligned with the slot.
Claim 4
Dependent Claim
42 words
AppaRatus according to claim 2 including a further settable selector means for specifying the closure to be opened, and an electromagnetic closure operator associated with each closure and responsive to the setting of the further selector means for opening the specified closure.
