Abstract: A fire ant trap having a stand comprising at least one prong for penetrating the surface of a fire ant mound and for supporting the trap above the mound. The fire ant trap also comprises an actuator assembly mounted atop the stand. The actuator assembly has a stalk member connected to the prong at a first end thereof and extending into a stem-like member at a second end thereof. The actuator assembly also comprises a timer and a stem-striking means for periodically impacting the stem member, and a container having an opening encircling and enclosing a portion of the stem member. In one aspect of the present invention there is provided a novel method for entrapping fire ants in a container, which is essentially a use of the aforesaid fire ant trap. This new method comprises the steps of; inserting a prong in a fire ant mound; vibrating slightly the prong for provoking the ants in that mound and for defensively urging these ants to climb the prong; encircling a portion of the prong in the container; periodically shaking that portion of the prong for dislodging the ants therefrom, and for causing these ants to fall into the container; and closing the container entrapping the ants thereinto.

Abstract: The subject invention relates to an anionic polymerization technique for synthesizing rubbery polymers of conjugated diolefin monomers, such as an rubbery copolymer of .alpha.-methylstyrene and 1,3-butadiene.  These rubbery copolymers exhibit an excellent combination of properties for utilization in tire tread rubber compounds.  They have high trans-isomer contents which leads to good treadwear characteristics and a broad molecular weight distribution which enhances processability.  This invention more specifically discloses a process for the synthesis of rubbery polymers which have a broad molecular weight distribution and which are particularly useful in tire tread rubber compounds, said process comprising the polymerization of at least one conjugated diolefin monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a dialkyl magnesium compound and (b) an alkali metal containing compound selected from the group consisting of alkali metal alkoxides, alkali metal phenoxides, alkali metal sulfoxides, alkali metal sulfonates, alkali metal carboxylates, alkyl substituted alkali metal phenoxides, alkali metal alkylamines, and alkali metal dialkylamines; wherein the molar ratio of the alkali metal containing compound to the dialkyl magnesium compound is within the range of about 6:1 to about 1:5.  In cases where rubbery copolymers containing .alpha.-methylstyrene are being synthesized the alkali metal in the alkali metal containing compound will normally be potassium, rubidium, or cesium with cesium being most preferred.

Title: High performance braided catheter
Inventor: SAMSON GENE
IPC: A61M25/00
Filed: 1996-04-26
Abstract: This is a catheter assembly and a section of that catheter assembly.  That catheter assembly may be used in accessing a tissue target within the body, typically a target which is accessible through the vascular system.  Central to the invention is the use of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated within the catheter body in such a way to create a catheter having an exceptionally thin wall, controlled stiffness, high resistance to kinking,  and  complete  recovery in vivo  from kinking situations.  The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section.  The braided ribbon reinforcing  member typically is  placed  between aflexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant.  The catheter sectionsmade according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.

IPC: H04L12/70
Filed: 1996-08-23
Abstract: A method of generating timing signals for constant bit rate data received over an asynchronous data network carrying, comprises recovering clock signals from at least two separate sources, selecting one of the sources to drive a phase-locked loop generating a high speed output signal locked to the selected source, dividing the high speed output signal to provide the required timing signals for said constant bit rate data, and continually monitoring the selected source. In the event of failure of the selected source, the phase-locked loop is allowed to free run in a hold-over mode while it is switched over to the other source.

Inventor: MARTINEZ JOHN C
IPC: H04M3/48
Filed: 1996-12-16
Abstract: A system and method are disclosed for providing an automatic call-back when a calling party number encounters a ring-no-answer condition upon calling a called party number. An exemplary system includes: (1) a switching network having switches for routing telephone calls; (2) a signaling network coupling switches in the switching network to one another for routing a calling party number and a called party number associated with a telephone call; and (3) a platform coupled to the switching network. The platform stores a calling party number and a called party number received from the switching network corresponding to a telephone call in which the calling party number encountered a ring-no-answer condition and requested an automatic call-back. A processor in the platform detects a subsequent telephone call involving the called party number and, at the conclusion of the subsequent telephone call, initiates the automatic call-back to the calling party number. Upon completing the automatic call-back to the calling party number, the platform transmits a pre-recorded announcement to the calling party number via the switching network indicating that the platform will attempt to complete a telephone call to the called party number in satisfaction of the calling party number's outstanding automatic call-back request. Upon completing the telephone call to the called party number, the platform merges the telephone call to the calling party number with that to the called party number.

Abstract: L'invention concerne un procédé pour convertir une matte de sulfure de cuivre et/ou un concentré de sulfure de cuivre en cuivre brut. Ce procédé consiste à introduire la matte/ou le concentré ainsi qu'un fondant approprié dans une cuve agitée contenant une phase de scories fondues et une phase de métal fondu, à injecter à l'aide d'une buse submergée un gaz oxydant capable de réagir avec la matte ou le concentré pour former une phase de cuivre brut à faible teneur en soufre, des scories et du dioxyde de soufre, l'injection de gaz se faisant de manière contrôlée pour qu'une proportion substantielle du gaz vienne en contact avec la phase de cuivre brut, et à séparer le cuivre brut des autres composants de la cuve. On peut ainsi atteindre un taux de soufre dans le cuivre brut égal ou inférieur au double de la valeur à l'équilibre pour le pourcentage de cuivre présent dans les scories.
