Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
An apparatus for sequentially charging samples to an analyzing apparatus for analysis comprising: conveyor means having a series of tray receivers for positioning trays in predetermined time sequence relative to said analyzing apparatus; means for inserting said trays containing said samples into and for removing said trays from said analyzing apparatus; and means for controlling the operation of said tray inserting and removing means, whereby said inserting and removing means sequentially inserts at least one of said trays into said analyzing apparatus, then is withdrawn from said analyzing apparatus leaving said at least one of said trays therein, and then is reinserted into said analyzing apparatus to remove said at least one of said said analyzing apparatus to remove said at least one trays from said analyzing apparatus following said analysis by moving the same in the direction of said conveyor means.
Claim 2
Independent Claim
142 words
An apparatus for sequentially charging samples to an analyzing apparatus for analysis comprising: conveyor means having a series of tray receivers for positioning trays in predetermined time sequence relative to said analyzing apparatus; means for inserting said trays containing said samples into and for removing said trays from said analyzing apparatus; and means for controlling the operation of said tray inserting and removing means, whereby said inserting and removing means sequentially inserts at least one of said trays into said analyzing apparatus, then is withdrawn from said analyzing apparatus leaving said at least one of said trays therein, and then is reinserted into said analyzing apparatus to remove said at least one of said said analyzing apparatus to remove said at least one trays from said analyzing apparatus following said analysis by moving the same in the direction of said conveyor means.
