Abstract: Abstract of the Disclosure A concealed hinge assembly for use with doors, hinged plates or the like comprises a mounting plate and a projecting base member connected to the mounting plate. A hinge bracket is screw-connected to said base member adjacent to one end of said hinge bracket and at its other end is so connected to one side of a pot-shaped member that the hinge bracket enters the pot-shaped mem ber during the closing move-ment. A slider which is biased by two parallel coiled compression springs is guided in the pot-shaped member in a radial plane and carries a cam, which during the closing movement cooperates with a projection or the like carried by the hinge bracket. To ensure that the cam will engage the hinge bracket with a relatively large lever arm during the final phase of the closing movement, the slider is U-shaped and comprises a crosspiece and side legs, which are guided in mating recesses of the pot-shaped member and at their free ends are provided with inwardly extending angled portions or projections, which are engaged by said compression springs at one end thereof whereas the compression springs bear at their other end on abutments consisting of stops carried by the pot-shaped member. The crosspiece carries the cam. One end portion of the hinge bracket extends beyond the projecting base member and runs up and slides on the cam during the closing movement.

Abstract: A DISTRIBUTED PRIORITIZED CONCENTRATOR            Abstract Disclosed is a distributed prioritized concentrator that manages the flow of information through high data rate communications paths.  The concentrator accumulates incoming packets as necessary, sorts the accumulated packets in parallel based on the relative priority of the packets, and transmits as many of its highest priority packets as there are available communication channels.  In its simplest form the prioritized concentrator comprises a parallel sorting network having some of its inputs connected to accept incoming signal packets and the remaining ones of its inputs connected to outputs of delay elements.  A number of the highest priority sorting network outputs are connected to outgoing communication channels, a number of lower priority sorting network outputs are connected to inputs of the delay elements and the remaining number of lowest priority sorting network outputs are left unconnected. More sophisticated forms which add various capabilities are also disclosed.

Abstract: ABSTRACT          A safety valve for controlling flow in a flow line is disclosed which is especially adapted for use in emergency control of a producing well. The apparatus in-cludes means for securing a punch out tube in series with the flow line and ramming means for ramming the punch out tube and displacing at least a portion of it from the flow path of the flow line and sealing the flow line.  The punch out tube comprises top, bottom and middle cylindri-cal members stacked end to end with an elastomeric seal provided in channels resulting from cooperating grooves formed in the end surfaces of the members.  When the mid-dle member is rammed, while the bottom and top members are fixed within the valve body, the middle member is displaced to a valve recess and the ram covers and seals the outlet flow path of the valve.           The valve is adapted to be attached between production casing of a production wellhead and a production tree.  The production tubing is supported within the valve body.  Production flow path is achieved by coupling of the punch out tube to the production tubing and the flow path of an annular packoff.           The production tree or a tubular extension to the tree is attached to the top of the valve body.  A method and means for accomplishing the method are provided for replacing the punch out tube without removing the production tree from the valve body.  A method of in-stalling the valve between a production wellhead and a pro-duction tree is also provided.

Abstract: ABSTRACT         Salts of multivalent cations in aqueous solution, with or without admixture with salts of monovalent cations, are converted into the respective acids or halogens of the anions of the salts and into water insoluble salts or ionically immobile compounds of the multivalent cations.         The conversion is effected by electrodialysis and electro-transport of the multivalent cations through a cation permeable membrane into aqueous solutions containing both agents that insolubilize or ionically immobilize the multivalent cations and a soluble salt of an acid, which acid in a one normal solution would have a pH no greater than three and forms water soluble salt with the multivalent cation.   The use of the added salt in the solution into which the multivalent cations are electrotransported minimizes fouling of the membrane and makes the electro-dialytic conversion efficient and with high capacity.

Abstract: ABSTRACT OF THE DISCLOSURE        Solid particles or viscous liquid droplets of core material (27) are encapsulated in a coating material (21) largely  as  single  particles  with  a  single  coherent coating, by feeding a suspension  of  the  two  materials onto   a   rotating  surface  (13).   The  suspension  is centrifugally  dispersed  by the  rotating  surface  into relatively  large  coated   particles   (27,   27a)   and relatively  small  droplets  (21a)  of coating  material.          Only   the   size  of  the  droplets  of  unused  coating corresponds to the droplets formed  from  atomization  of the  liquid coating material.  The  size  of  the  coated particles depends on the size of the  uncoated  particles and   is   much  less  dependent  upon  the   atomization characteristics  of  the  rotating surface.   Upon  being thrown from the rotating surface,  or  falling  from that surface,  the  droplets (21a) and coated  particles  (27, 27a) are solidified by exposure to  air and are separated by sieving, or the like.  The solidified droplets of pure coating material may be  recycled  into  the  suspension.          Coating of all particles is  achieved  by  dispersing the individual components  of  core  material  in the coating material  before  the  resulting  suspension reaches  the rotating surface.
