Abstract: Case 3-14597/ARL 339/14598/ARL 340/+ FO 7.3(SZ)EA/ap PREPARATION OF N-GLYCIDYL COMPOUNDS                 ABSTRACT OF THE DISCLOSURE         Aromatic N-glycidylamines are prepared by treatment of an amine having at least one, and preferably two or more aromatic amino hydrogen atoms, with epichlorohydrin in the presence, as catalyst, of a di- or higher-valent metal salt of nitric or perchloric acid, or of a carboxylic or sulphonic acid substituted by fluorine, chlorine or bromine  on the carbon atom alpha to the carboxylic or sulphonic  acid group, and dehydrochlorinating the product.  The presence of the metal salt gives a product having a higher glycidyl content and a lower viscosity than does the same reaction in the absence of such a salt.  Suitable aromatic amines include aniline, phenylene diamines, phenylene diamines substituted on the aromatic ring and bis(4-aminophenyl)methane.  The metal salt may be of, for example, magnesium, calcium, zinc, maganese, nickel, iron, lanthanum, vanadium, ytterbium or uranium.  The aromatic N-glycidylamines can be used as epoxide resins.  Due to their lower viscosity they are easier to  use than the corresponding prior art resins, and due to  their higher glycidyl content, the degree of crosslinking is higher in the cured resin, resulting in improved mechanical properties.

Abstract: ABSTRACT       An integrity indicator formed as an illuminable bead is combined with the pair of flat termimal blades of a mini-ature plug-in fuse and is positioned in a central window pro-vided in the top wall of the insulator housing thereof.  The housing defines a chamber having an open bottom and a central section with relatively narrow lateral sections in which up-per portions of the blades are secured. A fuse-wire extends across the central section conductively interconnecting the blades. The illuminable bead has a pair of wire leads extend-ing oppositely into the lateral sections of the chamber, each wire lead conductively contacting the upper portion of one of the blades and connecting the bead in parallel circuit with the fuse-wire. Clamping components formed on the interior of the top wall and on the upper portion of each terminal blade secure each wire lead in operative position.  Embodiments include the fuse-wire integrally formed with the blades as a unitary structure and formed separately as a three piece structure wherein opposite ends of the fuse-wire are also secured by the clamping components, the latter being either in coplanar relation with the blades or disposed perpendicu-lar to the plane of the blades.

Abstract: ABSTRACT OF THE DISCLOSURE       The  method  relates to manufacturing contact  spring sockets with a plurality of radially inward bowed contact springs  (6) clamped at one end in an approximately cylindrical socket body (1),  formed by a thin-walled deformable  sleeve. After  introduction of  the straight contact springs (6), formed by sections of a contact spring wire, into the socket body from one socket end they are made fast  by deformation of the socket material and their free ends are brought into supporting abutment on  an annulus  (5). This  is associated with a  mandrel for assisting assembly, which passes through  it and  which is  during the manufacture  introduced co-axially  into the  socket body  and finally withdrawn from it. Deformation of the socket body  to bow  the contact springs can be omitted, if in  accordance with` the invention  firstly the thin contact springs (6) with a diameter of maximally  0.2mm after introduction into the socket body (1), whereby their front  ends enter a co-axial annular gap between the socket inner wall and  the central head (7) of the  line connector  (2) which  projects into  the socket interior, are made fast in  a position approximately parallel  to the axis by deformation  of the head (7).  Subsequently the  mandrel (10) together with the annulus (5) is introduced into the socket  body (1).          The contact springs (6) are then by applying  axial pressure  on their ends converted  into a  shape bowed  into the interior of  the socket until they abut the mandrel (10).  Thereafter the mandrel is withdrawn from  the  socket  body until  relaxation  of the  permanently deformed contact springs and the annulus (5) is  held fast  in its  position in the socket body by folding over of the socket body edge.

Abstract: ABSTRACT OF THE DISCLOSURE A current differential pilot protective  relay apparatus  for  multi-terminal  high-voltage,  three-phase alternating current transmission lines.  The pilot pro-tective relay system provides comparison, at each terminal of the transmission line, of the currents flowing on each phase of the three-phase transmission line at each terminal thereof.  A novel scheme of  summing the  current-derived signals at one terminal reduces the number of receivers and transmitters necessary to send the local signal from each terminal to all of the other terminals.  Instead, the current-derived signals are summed at one of the terminals and the sum signal is then transmitted to each of the other terminals.
