Abstract: A self-supported, free standing, demountable, printing/endorsing apparatus including a demountably removable, replaceable, adjustable printing module having ribbon transporting and re-inking means integral therewith. Solenoid actuated means operably, drivingly connected to an impact member for impact engagement with the demountable printing member enabling the device to print on an item. Secondary impression producing means is demountably carried by the printing means and is adjustable relative to the impact member and together with the impact member forms an item receiving pathway normal to the impact member through which the item is transported. The impact member is Gimbal mounted relative to the pathway effectively enabling printing without regard to the flatness of the subject matter of the item, and without the prior art high impact forces generally employed.

Abstract translation: 一种自支撑的，独立的，可拆卸的印刷/认可装置，包括可拆卸的，可更换的可调整的印刷模块，其具有与其一体的带状输送和再墨水装置。 电磁致动装置可操作地驱动地连接到冲击构件，用于与可拆卸的打印构件冲击接合，使得装置能够在物品上打印。 二次印模产生装置可拆卸地由打印装置承载并且可相对于冲击构件调节，并且与冲击构件一起形成与冲击构件垂直的物品接收路径，物品通过该碰撞构件被运送。 撞击构件是相对于路径安装的万向节，其有效地实现打印，而不考虑物品的主体的平坦度，并且没有通常采用的现有技术的高冲击力。

Abstract: A collapsible screen assembly for a self-contained audio-visual apparatus comprising a forward wall having a translucent screen, a pair of foldable, spring-loaded side walls securing said forward wall to opposite sides of a projection opening in a front wall of the apparatus, and a hood pivotably secured to said front wall above said side walls so as to enclose said forward and side walls when folded and provide a light shield above said forward and side walls when the latter are opened. One side wall can be detached from said front wall and secured to the other side of said projection opening, thereby to provide a front screen projector. The assembly includes various brackets, locating posts, and other members, for facilitating operation, locking, and alignment of the screen assembly.
