Abstract: ABSTRACT OF THE DISCLOSURE          A pull tab connector for slide fastener sliders comprises a closed loop formed of a piece of resilient wire and having a pair of stems projecting from the loop, the stems being joined together and overlapping each other. The stems are aligned with each other in a plane perpendicular to the general plane of the loop.  In use, the stems of the loop are angularly moved about one another until they are aligned with each other in the general plane of the loop. Then the stems are inserted in an axial hole in a pull tab, while a pair of bottom portions of the loop are received in a transverse recess in the pull tab  which recess communicates with the axial hole.  The advance in the art is in that the connector is more safely  held in place and less likely to inadvertently disengage from the respective slider during the conveying on an assembly line.

Abstract of the Disclosure Disclosed is a connector for detachably and rotatably connecting one article to another article, which comprises an insert member to be attached to said one article and a receiving member having a space for insertion of said insert member, which is to be attached to said another member, wherein said insert member has an engaging annular peripheral portion having a void or hollow at the center thereof, a pair of spherical projections capable of elastic and reversional deformation are arranged in the insertion space of the receiving member to confront each other, and such a dimensional relation is established between the engaging annular peripheral portion and the spherical projections that the distance between apexes of the spherical projections is smaller than the thickness of the engaging annular peripheral portion and when said insert member is inserted into the receiving member, the engaging annular peripheral portion is rotatably gripped and supported by the peripheral parts of the paired spherical projections.  This connector has a simple structure and is excellent in the stoutness and the adaptability to the operations of attaching two articles to each other and detaching them from each other. This connector is used especially suitably for detachably and rotatably connecting a mop handle and a mop supporting frame in a large-size floor cleaner.                             - 1? -

Abstract: Système d'identification par exemple d'une personne en vue de la commande d'un appareil électrique, d'un appareil mécanique ou de tout autre appareil. Lorsqu'une clé a été accouplée à une serrure électronique, cette dernière émet tout d'abord par un circuit une impulsion unique permettant de charger dans un registre à décalage l'information codée contenue initialement dans une mémoire passive constituée par l'ensemble d'interrupteurs de la clé. La lecture du registre à décalage se fait ensuite au moyen d'une succession d'impulsions émises par un circuit de lecture série. Le nombre d'impulsions correspond au nombre de bits du registre à décalage grâce à l'existence d'un circuit d'arrêt de lecture comprenant un compteur d'impulsions. Dans une variante de réalisation, une partie des interrupteurs peut être remplacée par des fusibles dont l'état est modifiable à volonté par un circuit d'écriture contenu dans la clé électronique.

Abstract: Abstract of the Disclosure The use of polyisocyanates as binders in the preparation of particle boards is subject to the drawback that the boards exhibit a tendency to adhere to the face of the platens used in their formation.  This problem is minimized by incorporating minor amounts of certain phosphinic and or phosphonic acids or derivatives thereof or phosphites into the polyisocyanate to be used as binder.          The polyisocyanates and the phosphorus compounds are applied to the particles separately, or after preblending one with the other.  Whether the components are applied separately or in combination one with the other, they can each be applied either neat or in the form of an emulsion or emulsions.

Abstract: ABSTRACT OF THE DISCLOSURE          A method is disclosed for forming a net-like structure from a suitable material such as metal or a synthetic polymer. The structure avoids the problems of low tear strength at the joints in the mesh and enables novel shapes and designs to be formed that are not possible to make by other methods.  The method comprises the steps of forming a planar web from a suitable material in a plastic state, the forming providing for the planar web to have a substantially flat parting plane, the planar web having an expandible pattern of strands and strand joints with apertures therebetween, and expanding the planar web by forcing the exterior and interior of the web apart in a direction generally perpendicular to the planar web, to form a three dimensional net-like structure.

Abstract: ABSTRACT     An apparatus for supporting and handling spools of the type intended to carry wire, and for rotating such spools at relatively high speeds in order to fill them.  The appa-ratus comprises a housing having an access opening and a swivel carrier on the housing, capable of supporting the spool on one of its ends and of shifting the spool from the exterior of the housing to the interior thereof.  The car-rier, once it arrives at the interior, can lower the spool to an operative position on a special drive mechanism that is capable of rotating it.  In addition, a traverse mechanism is provided in the housing, for guiding and reciprocating a strand of wire as it is being wound onto the spool.  The advantage of the present invention is that by virtue of the arrangement wherein the carrier can swing the spool between the exterior and interior of the housing, lifting and han-dling of the spool is greatly facilitated.  This is partic-ularly important where spools weighing hundreds of pounds are being employed.
