Abstract: The device for transducing noise generated inside a body, in particular for transducing voice, for the detection outside of the body with a great damping of environmental noise consists essentially of a sheet element operating as a transducer associated with a supporting body adapted to provide a pressure between said sheet element and a contact surface forming a portion of the noise generating body so as to not transduce directly the noise as an acoustic phenomenon through the air but as a vibration affecting said contact surface and generated by the noise itself.

Abstract: A picnic trailer (10) has a wheeled rear frame (12) upon which picnic food preparation equipment, such as a hooded cooking grille (28), a sink (30) and a burner plate (32), is operatively supported. An elongated towbar (50) extends forwardly from the rear frame (18) and is connectable to a suitable towing vehicle. A vertical support frame structure interconnects the rear frame and a longitudinally intermediate portion of the towbar, and carries a collapsible, roofed picnic table structure. A rear end portion (50c) of the towbar, and a pair of diagonally oriented towing brace members, are pivotally con­nected to the longitudinally intermediate portion of the towbar and are releasably connectable to the rear frame for towing purposes. When the trailer is parked, and the picnic table and roof portions thereof set up for use, the brace members and the towbar rear end portion may be swung away from the rear frame to form a convenient walkthrough area between the picnic table and the cooking equipment on the rear frame.

Abstract: This relates to the construction of a pull tab integrally formed on a closure which is bonded to a container by way of a rupturable bond. Instead of utilizing the conventional pull tab which is normally integrally connected to the closure, the pull tab has been modified so as to provide two lines of bond rupturing forces as opposed to the prior art original single line with the two lines of bond rupturing forces having a tendency to spread in opposite directions and thereby greatly reducing the force required to initial a rupture of the bond between the closure and the container. Numerous different types of notches, openings and the like are provided to provide for the separate lines of bond rupturing forces. These notches, openings and the like also function to limit stray electric current induced into an intermediate metal layer of the closure and pull tab flowing into the pull tab, thereby reducing the power requirement for heating the closure to a bonding temperature.

Abstract: An impact mechanism for use in an impact printer, to deliver a printing force to drive a character element 22 against a platen 10 by means of a print tip 18 movable toward and away from the platen. A rockable bail bar 26 having an axis of rotation substantially parallel to the axis of the platen is constrained to limited angular movement toward and away from the platen by a prime mover 27 connected to the bail bar. A push rod 30 interconnects the print tip 18 and the bail bar 26 for delivering impact forces to the platen 10 as the bail bar is moved toward the platen. The push rod is normally coupled 28, 34, 36 to the bail bar for delivering impact forces to the platen and may be decoupled from the bail bar for drawing the print tip away from the platen so as to allow the character element 22 to be removed. A decoupling mechanism 54, 62 is provided to lift the push rod off of the bail bar and to recouple it to the bail bar as required.

Abstract: A culturing method and system are disclosed in which a cell culture broth is withdrawn from a culturing apparatus (1) to a filtration apparatus (6). The withdrawn broth is brought into contact with a membrane (7) for precision filtration. Then a non-toxic gas is blown into the broth by a sparger (9) while filtering the broth to separate the cells from waste liquid. Foams occurring on the surface of the broth due to gas bubbling are broken up by special layers (8). The separated cells are returned to the culture apparatus and the filtrate is withdrawn from the filtration apparatus to a filtrate tank (13). 
     The method and system have such advantages that a perfusion culture of a long period of time can be realized because the clogging of the filtration membrane is effectively prevented.

Abstract: A biochemical analysis apparatus comprises a movement device which moves analysis media (2) containing a reagent or an electrochemical sensor, which will interact with a specific biochemical substance contained in liquid samples (36) and give rise to changes in the analysis media, along a movement path connecting an introducing section (3) and an ejecting section (40). While the analysis media are present in the movement path, a measurement device (16, 50) measures changes which have occurred in analysis media. A reading device (18) reads information about correction values (18a), which are to be used in order to correct a calibration curve so that it becomes suitable for analysis media used in analyses, from a correction value recording medium (1). A correction device (6) corrects the calibration curve on the basis of the correction values. An operation device (7) uses the corrected calibration curve in order to determine the concentration or the activity of the specific biochemical substance in a liquid sample from the value measured by the measurement device.
