Title: Process for automatic control of percussion parameters of the striking pistonof an compressible pressurized fluid type apparatus and said apparatus
Inventor: COMARMOND JEAN S
IPC: B25D9/26
Filed: 1987-08-06
Granted: 1992-02-11
Abstract: A hydraulic percussion device comprises a housing defining a longitudinal cylinder, a piston longitudinally reciprocal in the cylinder and subdividing same into a front compartment and a rear compartment, and a tool engageable longitudinally with the piston at the front compartment. The compartments are alternately and oppositely hydraulically pressurized to move the piston forward to strike the tool while traveling at an end speed and to move the piston backward away from the tool, the rate of alternation being a frequency parameter and the speed being a force parameter. A controller varies at least one of the parameters by detecting how much the piston rebounds from the tool after striking same and operating the control means in accordance with how much rebound is detected. How much the piston rebounds can be detected by sensing the pressure in one of the compartments immediately after the piston strikes the tool. As rebound increases the pressure in the rear compartment increases relative to a set point or pressure in the front compartment decreases relative to a set point, and vice versa. Rebound can also be detected by sensing the pressure in one of the compartments and at one of the sides of the source and operating the control means in accordance with the differential between these sensed pressures.

Title: Cutting assembly for cutting thin strips of flexible material
Inventor: PLANETA MIREK
IPC: B65H19/26
Filed: 1988-02-15
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides a cutting assembly for cutting a moving strip of thin flexible material across its width, avoiding the possibility that the flexibility of the material will permit it to move away from the knife edge and not be cut, or be cut unevenly.  The assembly comprises a knife-supporting member which is engaged with the moving strip and displaces it out of its usual path close to a roll in the path, so that a very short length of the strip is between two contacting members in the path adjacent to the knife.  The knife is provided along its length with a plurality of distributed strip-engaging points pointing in the direction opposite to its direction of movement, which are moved into engagement with this short supported length of the strip, so that the strip movement drives it onto the points, and thereafter continues the movement of the strip into positive engagement with the succeeding knife edges.  The assembly is particularly suited for the handling of flattened tubes of plastic material as produced by a blown film plastics line, wherein the continuous strip must be cut for subsequent handling and/or storage.

Abstract: ABSTRACT OF THE DISCLOSURE.          A cutter cylinder - counter cylinder combination pair (5, 6) has cutter knives (13, 14) and counter elements (15, 16) thereon, respectively,preferably, located diametrically opposite each other.  A cutter knife (14) on one cylinder (6) cooperates with a   counter element (15) on the other cylinder (5). In addition to the cutter knife and counter elements, the cylinders carry deflection elements which are positioned relative to the direction of rotation of the cylinders in advance of the cutter knife for deflection of the web (2) into one of two selected paths (18, 19; 20, 21).  The deflection elements include a longer and comparatively stiff, elastic blade (11) on one cylinder and a short, and highly flexible blade (10) on the other cylinder.  The two blades grip the web (2) between themselves and, upon rotation of the cylinders, the stiffer, longer blade deflects the edge (26) of the web into the given path, permitting the shorter, resilient blade to flex.  After the sheet is deflected into the respective path, and for example after having been gripped by the path transport system, for example belts, it is cut  by the cutter knife engaging the cooperating cutter element of the cylinders upon continued rotation, the deflection elements gripping, anew, the web  just behind the cut edge.

Abstract: ABSORBENT ARTICLE HAVING FLOATING INNER CUFFS           ABSTRACT       An integral disposable absorbent article such as a diaper having an absorbent core, a backsheet, a continuous topsheet, an elastically contractible leg cuff along each longitudinal edge, and a pair of floating inner cuffs extending longitudinally along the absorbent article in at least the crotch region. The floating inner cuffs provide enhanced containment of body exudates and enhanced fit. The floating inner cuffs each preferably comprise a cuff layer, a base layer underlaying the cuff layer, a first seam that affixes a portion of the cuff layer to the base layer, a central seam that affixes another portion of the cuff layer to the base layer, an unadhered stand-up portion of the cuff layer between the first seam and the central seam, and a central elastic member having a pair of affixed portions and an unaffixed portion between the pair of affixed portions. The gathering action of the central elastic member causes both the unaffixed portion and the unadhered stand-up portion of the cuff layer to stand-up and be spaced away from the base layer to provide a ridge that contains body exudates. Since the unaffixed portion of the central elastic member is not affixed to the cuff layer or the base layer, the central elastic member is free to move or float within the floating inner cuff so that it may seek and be positioned adjacent the leg crease of the wearer to optimize fit and enhance containment.

Abstract: The present invention provides a new methodology and test composition for determining the presence of theophylline in test samples.  The methodology employs enzymes that utilize or recognize theophylline as a substrate to measure the concentration thereof in samples, including body fluids.  This new approach utilizes enzymes as opposed to traditional methods which use antibodies for the recognition of theophylline.  The enzymatic approach to theophylline determination is quick, simple and convenient and allows test systems to be made in liquid as well as in dry-chemistry formats.  Various protocols, systems or methodologies may be used for assaying and relating the results to the amount of theophylline present.  Methods for obtaining theophylline utilizing or recognizing enzymes are also described.
