Abstract
Abstract In an exemplary embodiment a compression carriage, adjustable by means of an electromotor, supports a compression localizer with which a switch is associated which disconnects the motor when the compression localizer engages the radiography subject. The connection between the motor and compression localizer can be selectively disengaged manually so as to allow manual movement of the compression localizer while the motor remains deenergized.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
140 words
A compression system for an X-ray diagnostic apparatus, comprising, a compression carriage movable along a predetermined path and having a compression localizer coupled therewith for movement into engagement with a radiaography subject, a motor for driving said compression carriage along the predetermined path to effect engagement of the compression localizer with the radiography subject, switch means controlling said motor and responsive to engagement of the compression localizer with the radiography subject to deactivate said motor, disengagement means providing a selectively a disengageable coupling between said motor and said compression localizer to disconnect said compression carriage from said motor, and manually actuatable control means connected to said disengagement means and manually actuatable to release said disengageable coupling to allow free movement of said compression carriage relative to said radiography subject and independently of whether said motor is running or is stopped.
Claim 2
Dependent Claim
140 words
A compression system for an X-ray diagnostic apparatus, comprising, a compression carriage movable along a predetermined path and having a compression localizer coupled therewith for movement into engagement with a radiaography subject, a motor for driving said compression carriage along the predetermined path to effect engagement of the compression localizer with the radiography subject, switch means controlling said motor and responsive to engagement of the compression localizer with the radiography subject to deactivate said motor, disengagement means providing a selectively a disengageable coupling between said motor and said compression localizer to disconnect said compression carriage from said motor, and manually actuatable control means connected to said disengagement means and manually actuatable to release said disengageable coupling to allow free movement of said compression carriage relative to said radiography subject and independently of whether said motor is running or is stopped.
Claim 3
Dependent Claim
98 words
A compression system according to claim 1, with said compression carriage has a carrier means mounted on the compression carriage on a pivot axis such that the compression localizer is released from engagement with a radiography subject when said carrier rotates, and said disengagement means comprising a locking device interposed between said carriage and said carrier means for selectively locking said carrier means against rotation, and said locking means being selectively manually releasable to allow manual movement of said compression localizer while the carriage remains in a fixed position and whether said motor is running or is stopped.
