Patent CA-2156457-A1 (CA)
Inventor: KISH FREDERICK A
IPC: F16B15/06
Filed: 1995-08-18
Abstract: A fastener is formed from carbon steel wire so as to have an elongate shank defining an axis, an enlarged head formed at one end of the shank, and a generally pointed tip formed at the other end of the shank.  The shank has a ringed portion formed with annular grooves defining annular rings and with helical grooves intersecting the annular grooves and defining helical ribs.  Each helical groove is symmetrical or asymmetrical with respect to a plane comprising the axis defined by the shank.  The elongate shank is smooth and generally cylindrical between the ringed portion and the generally pointed tip.  The fastener is heat-treated, zinc-plated, and chromate-coated. Substantially all of the shank or of the fastener, as a whole, is further coated with a polymeric material to resist corrosion, to improve ease of driving the fastener, and to increase holding power of the fastener when driven through a wood, plywood, or plasterboard workpiece and then through a steel framing member. Substantially all of the shank or of the fastener, as a whole, may be thus coated with the polymeric material. The polymeric material softens and flows upon penetration and rehardens.

IPC: H01P3/00
Filed: 1995-02-07
Abstract: Une ligne de transmission (500) présente une section limitée et une géométrie de ligne de transmission dont la tolérance d'impédance caractéristique est améliorée. La géométrie de la ligne de transmission comprend une combinaison unique d'un couplage transversal (509) et d'un couplage coplanaire (507) avec une plaque de réflexion (505) pour améliorer la tolérance de l'impédance caractéristique. On utilise d'abord un espace coplanaire plus important pour réduire l'erreur d'attaque, puis on réduit également les sensibilités à l'épaisseur du diélectrique interne grâce à un couplage transversal (509) et un couplage coplanaire (507) de manière à déterminer l'impédance caractéristique de la ligne de transmission (500). On élimine ensuite l'effet de l'erreur d'alignement dans le couplage transversal (509) en prévoyant les deux conducteurs (501, 503) porteurs de signaux sur la même couche.
Patent CA-2160675-A1 (CA)
Inventor: BUCHHOLZ HANS-VOLKER
IPC: E05F15/44
Filed: 1994-01-29
Abstract: A safety switch (1) has a support (2) of an elastomer and a through-going cavity (3). Within the cavity (3) are arranged electrical conductors (4) and (5) which in a rest condition are arranged at a distance (9) from one another. The electrical conductors (4,5) are each formed as a strip of carbon fibres and have one broad side (6) and (7) vulcanised to the support (2) either directly or by way of a coupling layer (8). Substantially perpendicular pressure (12,13) on the safety switch (1) leads to the deformation of the support (2) and eventually to the contact of the electrical conductors (4,5) with each other. By this means, safety functions are controlled.

Title: Composite pigmentary material
Inventor: SIMPSON LESLIE AINSLEY
IPC: C09D7/12
Filed: 1996-02-20
Abstract: A process for preparing a structured composite pigmentary material comprises forming a dispersion of uncoated particles of titanium dioxide at a pH value at which the particles have a surface charge and subjecting the dispersion to cross-flow filtration until the dispersion contains more than 50% by weight titanium dioxide. The concentrated dispersion is mixed with a dispersion of chemically distinct particles having a surface charge of opposite sign under conditions which ensure that the sign of the surface charge on either of the particulate materials is not reversed. In the resultant composite pigmentary material the titanium dioxide particles are held in association with the chemically distinct particles as a result of said surface charges. The structured composite can be used to produce paints having higher opacity than conventional paints containing an equivalent amount of titanium dioxide and the durability of these paints is better than a conventional paint containing a similar amount of uncoated titanium dioxide.

Abstract: A  soil-engaging  anchor  comprises  an elongated rod and at least one arcuate and twisted blade having a lower end fixedly secured to the lower end of the elongated rod.  The blade curves outwardly and laterally of the rod from its lower end to its upper  free  end.   An upper  soil-emerging  fastener member is capable of receiving a driving and rotating accessory for driving the elongated rod along with the blade into the soil and, after the elongated rod and the blade have been driven into the soil, for rotating the rod about its geometrical longitudinal axis to force  the  blade  into  the  soil  laterally  of  the elongated rod and thereby fixedly secure the anchor into the soil, and a fastening accessory for fastening an object to be anchored to the soil.   In a second embodiment, the blade is arcuate but not twisted, the rod is threaded, and the anchor comprises a sleeve member having an inner threaded surface engaged onto the lower end of the threaded rod.  The lower end of the  blade  is  then  fixedly secured to  the  sleeve member.   Rotation of the rod about its geometrical longitudinal axis into the sleeve member pulls this sleeve member toward the rod's upper end to thereby drive the arcuate blade into the soil.
