Abstract: A process for preparing a fluorinated polymer having carboxylic ester groups from a corresponding polymer having carboxylic acid groups is disclosed, wherein the polymer having carboxylic acid groups is treated with a selected ortho ester, acetal, ketal, borate ester or sulfite ester. The process is useful for assuring that all of the carboxylate groups of a polymer are in the ester form before an extrusion or lamination procedure, both of which are performed with heat and pressure, so as to preclude decarboxylation of free carboxylic acid groups during such procedure.

Abstract: An apparatus for applying particulate toner to an image-defining tacky surface upon a photo-element includes a hopper for receiving a particulate toner therein, the hopper being disposed above a transport path along which the photo-element is conveyed. The hopper has a slot extending substantially transversely to and communicating with the transport path. The apparatus is characterized by a reciprocating device for vertically moving the hopper in a reciprocating fashion toward and away from the transport path to impart vibrational energy to the toner to fluidize the same and cause the toner to flow through the slot to form a toner pool, from which pool toner is depositable on a photo-element being transported therebeneath. A toning pad attached to the hopper pats into the photo-element toner that has been deposited from the pool onto the photo-element.

Abstract: The system described is a positive cross identification system finding use in assuring that the proper medicaments are used for the proper patient. In this system, a patient's identification (I.D.) number is read by an optical scanner. Next, the I.D. number of the intended recipient on medicament container label is read by the optical scanner and the identification numbers compared in an electronic comparator. If comparison is indicated, an electronically actuated lock on the medicament container is unlocked.The lock described includes a lock body with a receptacle into which a split locking pin is introduced. An actuating pin spreads the members of the locking pin such that the locking pin cannot be removed. The locking pin can be removed only by withdrawing the actuating pin from the split members so that they are allowed to come together and be withdrawn from the aperture. Withdrawal of the actuating pin is accomplished by a solenoid actuated by the output of the comparator.
