Abstract: ABSTRACT OF THE DISCLOSURE      Rotary power slips mounted in the rotary table of an earth drilling rig and having slips for gripping and releasing pipe in the rotary table.  The air transfer ring has concentric grooves in the upper surface.  An annular seal ring is secured to the body of the rotary power slips and has a pair of air passageways. The air passageways lead to secondary fluid conduits in the body, which, in turn, lead to each end of the pneumatic cylinders to raise and lower the slips. Expansive rings are secured to the surface of the air transfer ring by mounting the edges of the rings into the grooves in the air transfer ring.   When air pressure is applied through one of the primary fluid conduits, one of the expansive rings expands and cooperates with the lower surface of the seal ring to form an expansive fluid duct.  The air pressure flows through a perforation in the expansive ring into the expansive fluid duct, and then through the air passageway and the secondary fluid conduit to the pneumatic cylinders. A pilot operated check valve maintains pressure in one end of the cylinders to keep the slips in the upper, retracted position. The check valve is opened when positive pressure is applied to the other end of the cylinders.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to an apparatus and method for directing a constant velocity laminar flow of a fluid along a surface of a planar substrate.  The apparatus comprises a plurality of serially arranged, individual passageways (38, 44, 50, 60, 64, 66, 80, 82) interconnecting an inlet (30) and an outlet (34).  The inlet is adapted to be connected to a supply of fluid, while the outlet is positioned adjacent the surface of the substrate for directing the uniform laminar flow of fluid onto the substrate surface.  The individual passageways are adapted to vary the velocity of the fluid as it passes through the passageways to ensure that a laminar flow of constant velocity is produced along the surface of the substrate.  In the preferred embodiment of the invention, the apparatus is utilized to apply a metal oxide coating to a sheet of moving glass.  In these instances, the outlet is an elongate nozzle extending transversely relative to the path of the moving glass to enable a gaseous reactant utilized to form the metal oxide coating to be applied across the entire width of the glass sheet.  In one embodiment of the invention, the individual passageways are alternating converging and diverging passageways which function to evenly distribute the fluid within the passageways such that the fluid exits the elongate outlet at a relatively constant velocity to produce a uniform laminar flow of the gaseous reactant across the glass sheet.

Abstract: ABSTRACT OF THE DISCLOSURE    A phase detecting apparatus comprises a first PLL and a second PLL having a response time shorter than the response time of the first PLL.  An AC voltage signal produced by the first PLL which is in phase with the detected AC voltage except until the expiration of the response time of the first PULL after an abrupt change in the phase of the detected AC voltage is normally applied to the second PLL. Until expiration of the response time of the first PLL after rising of the detected AC voltage to a certain level, the detected AC voltage is applied, in place of the AC voltage signal produced by the first PLL, to the second PLL.  The second PLL provides a digital signal indicative of the phase of the detected AC voltage.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a vertical catalytic reactor contain-ing two catalyst beds located one above the other and connected in parallel flow arrangement.  The effluent from the lower catalyst bed bypasses the adjacent upper bed, and the effluents from both beds are combined and pass out of the reactor at its upper end.  A conical grid plate directing uniform fluid flow to the lower catalyst bed is supported principally on rigid thermal insulation in the lower head, and is restrained from upward move-ment by tension members.  The lower grid assembly also supports the upper catalyst bed and its grid plate.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention discloses a new concrete forming system and components therefor, particularly adapted for forming of vaulted ceilings and for use in buildings wherein the floors at the edges thereof have upwardly extending sills and/or wherein the ceilings have been dropped by a similiar ledge or sill thereby significantly reducing the clear area through which a truss can be removed.  The truss comprises a top chord and a bottom chord interconected by upright members and diagonal bracing members. A number of adjustable extension legs are associated with the upright members and are telescopically received within an upright member such that a leg extending to the upper side of the truss can overlap with a leg extending to the lower side of the truss, whereby the legs extending above the truss can be adjusted and maintained indpendent of the legs extending below the truss.  In contrast to the prior art practise of having the upper chord of the truss at the lowest level of the ceiling with "packing" thereabove to define and support the concrete forming surface.   The present system provides load collecting support beams adjustably secured above the upper chord of the truss by extendable legs whereby the position of the support beam can vary relative to the top chord of the truss.  The height of the truss is used to accomodate the extendable legs which position the truss above the floor as well as the extendable legs supporting the load collecting beam, whereby the amount of packing and the time required to initially set up the system for a given building are reduced.  Therefore, the present invention relates to improvements in flying forms and components thereof and in particular to a system which is more flexible and adjustable for the forming of vaulted ceilings.

Abstract: MOUNTABLE AND DEMOUNTABLE PARTITION STRUCTURE FOR MOTOR VEHICLES          ABSTRACT OF THE DISCLOSURE:         A  mountable  and demountable partition  structure  for motor  vehicles,  such as vans and station wagons,  is  provided.          The  partition  comprises  a panel which  is  adapted  to  extend substantially  from  top to bottom and from side to side  of  the vehicle,  where  it is mounted;  and is mounted by fastener means extending  downwardly through brackets at the bottom edge of  the panel  into  plates  secured in the floor  of  the  vehicle,  and through brackets at the top edge of the panel into tracks mounted between  roof  ribs  in  the roof  of  the  vehicle.   The  panel comprises three panel portions,  each of which extends across the width  of  the panel,  where the upper panel  portion  is  tilted forwardly  from  the vertical,  and the lower portion  is  tilted rearwardly  from  the  vertical,   when  mounted.    The  overall configuration  of  the panel is that of a forwardly bowed  panel; and at least the upper and middle panel portions of the panel are made   of   a  solid,   translucent  material   such   as   sheet polycarbonate,   thereby   providing  a  clear,   glare-free  and unobstructed  rearwards  view  for the  driver  of  the  vehicle.          Because  of  its  bowed  configuration,  the  partition  provides additional  safety  to the occupants of the vehicle in the  event that a forwardly moving object strikes the partition,  as in  the event  of a collision when passengers or cargo are not secured in the  rear  of the vehicle.   The partition  provides  for  energy efficiency by permitting greater loading of the cargo compartment of   the  vehicle,   as  well  as  maintaining  heating  or   air conditioning effects to the passenger compartment of the vehicle.

Abstract: Ce procédé se rapporte à la comparaison d'une courbe de vitesse mesurée (S) avec une courbe de vitesse de référence (R) d'une signature par exemple. Les signaux de la référence sont lus par le rectangle (A) et ceux de la courbe mesurée le sont par le rectangle (8). La courbe de vitesse mesurée est divisée en segments égaux. La position de chaque segment de la courbe mesurée est déterminée par rapport au segment correspondant de la courbe de référence jusqu'à ce que l'on obtienne la meilleure concordance (C1). Ensuite, chaque segment de la courbe mesurée est affecté d'un facteur de correction de son échelle de temps pour obtenir la meilleure corrélation des deux segments (C2). Les segments de la courbe mesurée ainsi normalisés sont alors comparés aux segments correspondants de la courbe de référence (D), puis les résultats sont transmis à un losange de décision (E) qui détermine si les résultats sont acceptables.
