Abstract: L'invention concerne des conditionnements individuels permettant d'introduire, de manière hygiénique, un dispositif absorbant dans l'espace interlabial d'une femme. Ce conditionnement individuel comprend une enveloppe destinée à emballer le dispositif absorbant. L'enveloppe comprend une feuille souple qui enveloppe le dispositif absorbant. La feuille souple étant au moins partiellement retirée du dispositif absorbant, une partie au moins de l'enveloppe reste entre les mains de l'utilisatrice. L'article absorbant, lorsqu'il est introduit dans l'espace interlabial, empêche que les mains de l'utilisatrice ne viennent en contact avec l'article absorbant lors de l'introduction hygiénique. L'enveloppe est pliée autour du dispositif absorbant par rapport à l'axe longitudinal de la partie inférieure ce qui forme un pli longitudinal, une extrémité opposée ouverte, et des bords latéraux transversaux. L'extrémité opposée ouverte et les bords latéraux transversaux sont fermés hermétiquement de façon à former le conditionnement individuel.

Abstract: A stripper packer includes a main body having a first end and a second end. A passage extends through the main body from the first end to the second end, thereby facilitating the passage of coiled tubing through the main body when the coiled tubing is being stripped in and out of a well bore. A primary sealing element encircles the passage. A secondary sealing element encircles the passage. A piston is positioned within the main body. Movement of the piston in a first direction toward the first end of the main body applies a compressive force to the primary sealing element thereby causing the primary sealing element to expand inwardly to form a circumferential seal around the coiled tubing. Movement of the piston in a second direction toward the second end of the main body applies a compressive force to the secondary sealing element thereby causing the secondary sealing element to expand inwardly to form a circumferential seal around the coiled tubing.

Abstract: The invention facilitates a determination of the rate at which soil organic nitrogen is converted to inorganic nitrogen or mineral nitrogen. This conversion is known as N-mineralization. The total release of plant available nitrogen in a soil, i.e. the gross N-mineralization rate quantifies the conversion in the soil of organic nitrogen to inorganic nitrogen. The present invention provides a quick and reliable method for measuring the gross N-mineralization rate of a soil sample. The method exploits that a microbial enzyme activity of a functional ornithine acid cycle present in said sample is correlatable with the rate of gross N-mineralization of that same sample. The method of the invention can be used e.g. in a determination of the amount of a nitrogen-containing fertiliser to be applied to a soil such as e.g. a field of agricultural crops.

Title: Adaptively peaked super-regenerative filter
Inventor: FLANAGAN ROBERT C
IPC: H03H11/04
Filed: 2000-09-13
Granted: 2010-06-29
Abstract: In accordance with one form of the present invention, an Adaptively Peaked Super-Regenerative Filter (APSRF) is provided, which preferably includes an interference suppression system (ISS), a summing block, a phase splitter, one or more variable attenuators, three couplers, an amplifier and a filter. The APSRF provides for significant narrowing of the bandwidth and a significant increase in the SNR and Q transfer function of the filter. The output of the amplifier or filter is sampled by one of the couplers and used as a reference sample signal to the ISS. The ISS includes an adaptive loop, which adjusts the reference sample signal in phase and amplitude to form a replica signal. The replica signal is designed to cancel an input sample signal taken from another coupler and applied to the summing block. An output of the summing block provides an error sample signal to the ISS, which enables the ISS to adaptively optimize the nulling function by adjusting the amplitude and phase of the replica signal. The phase splitter provides a copy of the replica signal having a 180--degree phase shift. This copy is in phase with the input signal, and provides a positive or regenerative feedback signal, which is coupled to the input signal. The copy of the replica signal is passed through a variable attenuator, and by varying the magnitude of the regenerative feedback, the degree of bandwidth reduction can be adjusted over a broad range.

Abstract: A cut heighth adjustment mechanism is provided for use with a vegetation cutting device, such as a tractor, and including a front-mounted cutting deck. To achieve heighth adjustment of a front portion of the intended deck, there is provided a heighth positioning arm fitted and secured between a bracket and a mounting structure adapted to attach to the deck of the cutting device. Adjustment of the arm and hence, the front of the deck, is accomplished by securing the arm to a selection of perforations occurring in both the bracket and the mounting structure. Rear adjustment of the deck is accomplished by connection of a drive member to a vertical upstanding portion also having perforations and attached to the deck. To allow a user to visually inspect which range of cut heighth has been selected, perforations are provided both in the bracket and the mounting structure, each corresponding similarly to each other to designate a particular range of cut heighth. Further, the adjustment mechanism permits the user to obtain a lower profile of cut than is currently permitted, thus enabling cutting to occur under low hanging vegetation and shrubbery.

Abstract: An extrusion die for extruding a chemical functional additive for making a disposable paper product comprises a supply port and a distribution channel in fluid communication with the supply port. The distribution channel terminates with at least one discharge mouth having a passage cross-section therethrough. The discharge mouth comprises an entry orifice having an entry open area Ae, an exit orifice having an exit open area Ax, and a discharge distance defined between the entry orifice and the exit orifice. The exit open area Ax is greater than the entry open area Ae. This ensures that contaminants would pass through the discharge mouth whereby plugging thereof is substantially avoided. Preferably, the passage cross-section of the discharge mouth continuously and gradually increases from the entry orifice to the exit orifice.
