Patent BR-8805026-A (BR)
Inventor: TURNER HOWARD WILLIAM
IPC: B01J31/14
Filed: 1988-01-27
Abstract: A catalyst is prepared by combining a first compound consisting of a bis(cyclopentadienyl)zirconium compound having one of the following general formulae:Wherein:(A-Cp) is either (Cp)(Cp*) or Cp-A'-Cp* and Cp and Cp* are the same or different substituted or unsubstituted cyclopentadienyl radicals;A' is a covalent bridging group;L is an olefin, diolefin or aryne ligand;Zr is zirconium;X<sub>1</sub> and X<sub>2</sub> are, independently, selected from the group consisting of hydride radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like;X'<sub>1</sub> and X'<sub>2</sub> are joined and bound to the zirconium atom to form a metallacycle, in which the zirconium, X'<sub>1</sub> and X'<sub>2</sub> form a hydrocarbocyclic ring containing from about 3 to about 20 carbon atoms; andR is a substituent on one of the cyclopentadienyl radicals which is also bound to the zirconium atom. With a second compound comprising a cation capable of donating a proton and a bulky, labile anion containing a single boron atom, and a plurality of aromatic radicals capable of stabilizing the zirconium cation formally having a coordination number of 3 and a valence of +4 which is formed as a result of the combination, said second compound having the general formula:         [L'-H]<sup>+</sup>[BAr<sub>1</sub>Ar<sub>2</sub>X<sub>3</sub>X<sub>4</sub>]<sup>-</sup>Wherein:L' is a neutral Lewis base;H is a hydrogen atom;[L'-H]<sup>+</sup> is a Bronsted acid;B is boron in a valence state of 3;Ar<sub>1</sub> and Ar<sub>2</sub> are the same or different aromatic or substituted-aromatic hydrocarbon radicals which may be linked to each other through a stable bridging group; andX<sub>3</sub> and X<sub>4</sub> are, independently, selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like. Many of the catalysts thus formed are stable and isolable and may be recovered and stored. The catalysts may be preformed and then used to polymerize olefins, diolefins and/or acetylenically unsaturated compounds either alone or in combination with each other or with other monomers or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined in a suitable solvent or diluent at a temperature within the range from about -100°C to about 300°C. The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal. The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.

Abstract: A glue trap for trapping vermin, such as insects, rodents and the like. In particular, a glue trap for trapping cockroaches, having a design which significantly enhances the number of cockroaches which are caught. The glue trap is designed for use specifically in target areas such as corner locations and confined spaces which are regions frequented by cockroaches, and has a unique right angled corner portion and a top opening in the corner substantially above the glue surface. A three-dimensional trap with top and side openings is provided through which vermin may access the trap interior. The trap may include an attractant to entice cockroaches and provides a slippery surface and/or substantially smooth interior surfaces juxtaposed to the adhesive so that once a cockroach is caught on the adhesive it is unable to use either a surrounding surface or edge to pull itself free. The trap and packages of at least two traps which are easily split apart by a perforation line with or without a tear-away strip and/or bendable flaps, can be formed from an integral blank of foldable sheet material.

Abstract: A dual dental tray assembly is provided which includes a pliable resilient outer dental tray using a pre-formed thin inner tray of thermoplastic material that nests inside the pliable outer tray. The two are heated to between 145 DEG -160 DEG  F. During this time the inner tray is more formable, allowing for the inner tray to be accurately formed over the patient's teeth. The outer tray also prolongs the time during which the inner tray is moldable. The outer tray also operates as a seal with the gums to create a better vacuum created by the patient's sucking. Thus, the inner tray, once formed and cooled, becomes hard and flexible again and provides a thin hard dental tray as accurate as dental trays produced by dentists in their labs on models. The thinner, hard dental tray can then be used for dental treatments including bleaching, fluoride applications, and other dental operations, including provisional crowns and other dental work. The outer tray is usable for fluoride gel treatments.

Abstract: A convenient process for making builder material which has substantially improved performance and is significantly less expensive than previous builders is provided. The builder material has improved performance in that it unexpectedly has a high calcium ion exchange capacity and rate, and is easy to handle, process and disperse in washing solutions. In its broadest aspect, the invention is directed to a process involving converting starting materials (via any means including but not limited to heating and precipitating) to a builder material having at least one crystalline microstructure including a carbonate anion, calcium cation and at least one water-soluble cation. The microstructure should have a sufficient number of anions and cations so as to be "balanced" or "neutral" in charge.

Abstract: A cable (5) is inserted, by way of a free end (2.1), into a tube (2) wound around a tube reel (1) which is fixed, with its winding axis (y) vertical, onto a carrier (7). The carrier with the tube reel is subjected to a periodical movement having a vertical component and a longitudinal component. The vertical component is a vertical oscillation having a period (P) and an amplitude (Av=gP2/32) for an, at any rate approximately, "free-fall" movement during part of each period, preferably during half a period. The longitudinal component is an oscillating rotation around the vertical winding axis of the tube reel having the same period (P) and an amplitude (AL). The "free-fall" movement is preferably commenced when the rotational direction of the oscillating rotation is reversed and becomes backward, as opposed to the insertion direction of the cable.
