Abstract: ABSTRACT OF THE DISCLOSURE        Books to be jacketed are fed in open position and in a first direction to an assembly station where the covers of a fresh-ly arrived book enter between the central panel and the flaps of a prefabricated jacket which is transported to the assembly station in second direction counter to the first direction. The feed of books is interrupted in response to an interruption of the transport of jackets, or vice versa, and each book is inspected prior to being fed to the assembly station in order to determine whether or not the end papers adhere to the respective covers. The jackets are prefabricated from rectangular blanks which are withdrawn from a stack and are folded by pairs of coating mechanical folding devices at least one which is heated to provide each jacket with perman-ent creases in regions where the flaps adhere to the central panel. Jacket books are closed and descend into a channel or directly onto a conveyor from which they can be removed by hand for stack-ing at one or both sides of the assembly station.

Abstract: TUBE FOR INNER END FEEDOUT OF FLEXIBLE MATERIAL AND PACKAGE UTILIZING THE SAME         ABSTRACT OF THE DISCLOSURE           For guiding flexible material wound in a figure-8 package with inner end feedout, a coil is enclosed in a container with walls of corrugated card-board.  The payout of the material is guided by a tube having a flange adjacent the outer end, and two outwardly extending projections between the flange and the outer end, leaving a space therebetween. The inner edges of the projections are slanted in opposite directions.  The tube is inserted into a coil, which is then inserted into a container formed of corrugated material.  The corrugated material has an opening equal in diameter to the diameter of the tube and notches on either side of such opening extending in the direction of the corrugations.  The outer end of the tube is brought through this opening, with the projections extending through the notches, and is then turned by 90°.  The thickness of the cardboard is slightly less than the space between the projections and the flange. Turning the tube causes the notches to ride up on the wall and to dig into it, so as to prevent accidental turning of the tube to an unlocked position.  The projections rest against uninterrupted corrugations in the wall of the container.

Abstract: ABSTRACT OF THE DISCLOSURE    Symbol decoding method and means are provided for identify-ing special symbols such as "start of tag" and "end of tag" form-ing part of a record contained on record media or placed directly on articles or credit cards in coded form such as a bar code.          Various clock frequencies are applied through gates to counters for periods of time corresponding to sensed characteristics such as width of various components of the coded record in such manner that the final condition of the counter at the completion of sensing of the symbol provides an indication of the identity of the symbol.  The counters may be of the up-down type, so that clock signals corresponding to different code components can cause the counter to count in different directions.  Two counters are employed for detection of each of the "start of tag" and "end of tag" symbols so that the testing for the symbols can be com-menced with successive components of the code.
