Filed: 1984-03-14
Granted: 1988-07-06
Abstract: A continuous, high speed method for elasticizing articles such as disposable diapers, incontinent briefs, and the like by securing an elastically contractible element to a moving, interconnected web of said articles, said elastically contractible element causing the discrete articles cut from the web to shirr in a direction substantially perpendicular to the direction of web travel. Prior to application and securement, the web from which the elastically contractible elements are cut is laterally stretched while at an elevated temperature which is less than its crystalline melting temperature and allowed to cool to ambient temperature. This molecularly orients the elastomeric material and makes the web dimensionally heat unstable parallel to the direction of stretching. The elastically contractible element is cut from the web of the heat unstable elastomeric material so that the length of the element coincides with the width of the heat unstable web. The elastically contractible element is applied to the moving web of interconnected articles while in a substantially untensioned, molecularly oriented, dimensionally heat unstable condition. The elastically contractible element is so oriented when applied to the web of interconnected articles that the direction of lateral stretching applied to the elastomeric web to impart a dimensionally heat unstable condition is aligned substantially perpendicular to the direction of travel of the web of interconnected articles. The discrete articles cut from the web are thereafter subjected to an external stimulus, such as heat, to cause the elastically contractible element to shrink and become dimensionally heat stable and elastic in a direction parallel to its length, thereby imparting shirring in a direction substantially perpendicular to the direction of web travel.

Abstract: An electric signal to pneumatic signal transducer (10) comprises a nozzle (12) that accepts an input pneumatic supply and expels a gas stream (20). A receiver (16) that is spaced from the nozzle (12) is positioned to recover at least a portion of the gas stream (20). The recovered portion constitutes a pneumatic output signal (Pout). The position of a deflector (14) relative to the gas stream (20) is controlled by an electric input signal (Iin) to aerodynamically deflect the gas stream (20) expelled from the nozzle (12). The aerodynamic deflection affects the magnitude of the portion of the gas stream (20) recovered by the receiver (16) in a manner having a known relationship to the electric input signal, thereby generating a pneumatic output signal responsive to the electric input signal.

Abstract: A reclining seat support (3) and a backrest support (4) are hinged on a chair frame with a support part (1) via a lever (7) by means of hinges (5, 8). Coupled to the backrest-side end of the seat support (3) is a link chain (15) which is connected at its other end to a slide (20) and a backrest (21). The link chain (15) causes the slide (20) to be moved downwards with the backrest when the chair is reclined. By this means, the pulling-out effect during the transition from the normal position into the reclined position of the lever is eliminated. However, if the chair frame is used as a chair without a link chain (15), although slightly less seating comfort is achieved by the reclining seat support, the expenditure is correspondingly less. <IMAGE>
