Abstract: ABSTRACT OF THE DISCLOSURE            This invention provides a fluid shear device for emulsifying or mixing liquids, and also useful for de-aeration.  A central chamber with a tangential inlet has a forward wall perpendicular to the chamber axis and a rearward wall with a reverse curve in profile such that the rearward wall is more parallel to the forward wall in its outer portion than its inner portion.  This produces a number of advantages in terms of pressure energy released, which energy is then available for the shearing and mixing function.

Abstract: LOCK KNOB CONTROL MECHANISM     Abstract of the Disclosure Lock knob control mechanism comprising a three-piece cam assembly made up of a central cam actuator and two outside knob guides that may be selectively assembled to make the two knobs at opposite sides of a door active or inactive.  An inactive knob guide makes its knob non-rotatable.  An active knob guide cooperates with the central cam actuator and a locking pawl that prevents rotation of its knob but may be rendered inoperative electrically from a remote point by authorized personnel or mechanically in response to actuation of the key for that lock.  The knob control also includes a retainer for securing a knob in place on the door which can be released only when the door is open, with a rose for the knob secured to the door by screws that are covered by the knob so that with the door closed there are no visible means for removing the knob.

Abstract: ABSTRACT OF THE DISCLOSURE           A rolling mill section for rolling or roughing slab, plate, billet or structural section is provided with a load sensing arrangement for determining if the extent of non-synchronization between the respective drive motors of the rougher stand and the edger stand is sufficient to cause significant tensile or comprehensive loading in the member being rolled, at it passes between the two stands.  The existence of such loading is determined by providing a coupling or utilizing existing mechanical connection of the one or both structures of the stands, and measuring reactive forces generated thereat by the passage of the member being rolled, tending to displace one stand relative to the other.  A readout from the force measuring means is used to control the relative torques of the respective stand motors so as to promote synchronicity of the two drives, in order to reduce damaging overloads in the edger or in the rougher which otherwise result when significant lack of synchronicity is present.

Abstract: ABSTRACT OF THE DISCLOSURE           A straightedge having incremental markings along two opposite edges, the spacing of the markings being progressively decreased toward a theoretcial vanishing point to provide a perspective scale.  The straightedge has a rigid spine, with two edge members of transparent material on which the graduations are marked.  The edge members are offset toward opposite faces of the spine, so that when one member is held flat on a work surface, the other member is raised above the surface, allowing the raised edge to be used to guide or support a pen, brush, or the like without the ink or other fluid marking material running under the edge.  The raised edge may be rocked into contact with the work surface and the upper edge serving as a guide or support.  In a further manner of use, the straightedge facilitates rapid basic layout of a perspective drawing, such as an architectural rendering.

Granted: 1981-05-12
Abstract: L'invention est relative si un dispositif et un procédé de régulation d'une opération de moulage d'un métal par coulée à basse pression dans un, moule alimenté par dessous par une pompe électromagnétique.  L'opération comporte les phases suivantes à partir d'une position de repos dans laquelle la métal est maintenu à une altitude légèrement inférieure à celle de l'entrée du moule.  On remplie le moule, vitesse croissante, par application d'une tension croissante sur la pompe et jusqu'à une tension correspondant à une hauteur de refoulement légèrement supérieure à celle du haut du moule; on maintien cette tension jusqu'à formation d'une peau contre les parois internes du moule; on solidifie avec application d'une pression accrue jusqu'à ce que le front de solidification atteigne l'entrée du moule.  Le procédé est caractérisé par le fait qu'on utilise des mesures de température du moule et de température du métal dans le four de fusion pour régler la durée des deux premières phases dans le sens d'une réduction de durée pour une diminution de la température du moule ou de la température du métal dans le four.

Abstract: Abstract of the Disclosure.      A flow meter comprising a fluidic switching device coupled as a free-running oscillator. The frequency is dependent on the flow rate of the medium. The device called a fluidistor has a nozzle (edges) arranged upstream of the control chambers and a first region downstream of the control chambers, within which first region the flow of medium lies either on one side or the other side in dependence upon the pressure conditions and flow conditions prevailing in the oscillator circuit. A second region is located downstream of said first region. Mutually spaced apart orifices of a cross-connecting line, said orifices pre-ferably being arranged transversely to the flow direction, are arranged at a location at which the stream of fluid is deflected, in a manner such that said orifices are coupled together, through a line. In said line is a pressure-sensing device arranged to generate a signal cor-responding to the measuring result and that said deflection location is placed downstream of the control chambers.
