Abstract:
Novel polyanionic polymers including families of repeat units, such as maleic, itaconic, and sulfonate repeat units. The polymers are at least tetrapolymers and may be in the acid form or as partial or complete salts. The polymers may be synthesized using free radical initiators in the presence of vanadium compounds. The polymers have a variety of uses, particularly in agricultural contexts.
Abstract:
A gas disperser (1) for use in directing toxic gases released from slurry tanks (7) during slurry mixing with a slurry mixer (2) away from operatives (9) and animals, the gas disperser (1) being adaptable to be integral or combined with the slurry mixer (2) to provide a unitary slurry mixer (2) and gas disperser (1) for safe mixing of slurry in enclosed spaces such the slurry tanks (7) of slatted houses..
Abstract:
Le palier (100) d'un module (9; 9M) d'une barre de coupe équipant une machine utilisable notamment en agriculture, arboriculture et viticulture - cette barre étant reliée à un support solidaire d'un cadre et pourvue d'au mois un module comprenant au moins un palier solidaire dudit cadre, ce palier portant un arbre auquel est fixé au moins un organe de coupe pouvant être entraîné en rotation, le module pouvant en outre comporter au moins une poulie et être relié à un moteur est conformé et agencé de sorte que le module (9; 9M) - peut être relié au cadre (7) ou en être retiré de façon simple et rapide, d'un même côté chaque fois, par la seule action d'organes d'assemblage / désassenblage (118). Le cadre (7) est formé d'un châssis (70) auquel est associé un déflecteur (80), ces éléments (70, 80) étant solidarisés (ou désolidarisés) par le seul effet du montage (ou du démontage) du module (9; 9M) sur le (ou du) cadre.
Abstract:
A soil-working implement comprising a frame (1) provided with two side walls and arranged to be mounted on two wheels or applied to the rear lift of a tractor, a series of hoes (8) rotating about a horizontal axis perpendicular to the direction in which the implement advances, and a grid (10) positioned to the rear of said series of rotary hoes, in which the grid is adjustable relative to the series of hoes, and is associated with a rear levelling bar.
Abstract:
A shovel includes a handle (11) and a blade (12) in which a central portion of the blade contains a plurality of perforations (16). The perforations are in an array of rows and columns and the rows extend in a direction perpendicular to the handle. The perforations are elongated and have a length in a direction approximately perpendicular to the handle. The perforations in adjoining columns and rows are interleaved a predetermined amount and the total area of the perforations is about one-half the area of the central portion. The blade is made from a single sheet of steel which is punched and bent to shape.
Abstract:
A mixing and distributing apparatus comprises a mobile elongate, substantially cylindrical, container (10) to receive foodstuff materials through an elongate opening (12) in a top thereof. The container (10) is provided with mixing means having a horizontally orientated, rotatable shaft carrying a plurality of mixing paddles (11) therearound. The paddles (11) have blades, on rotation of the shaft, to sweep around the inside surface of the container (10). Means are provided to rotate the shaft. An elongate guard means (16, 18) is hinged to and along all or part of one longitudinal side of the opening (12). The guard means (16, 18) is movable between an outboard position to allow materials to be placed through the opening (12) and an inboard position whereat it partially covers the opening (12).
Abstract:
An array (1) of tools for use in planting in combination produce a variety of patterns of operation to provide a required density and pattern of plants. Each tool (6) is provided with an independent sensory/motor system (9) which moves the tool (6) independently with respect to the array (1). A controller (14) in response to a control signal positions the tool (6) automatically in a desired location. The control signal may be an environmental cue such as a region of illumination controlled by the user, or may be a signal generated by a neighbouring tool.
Abstract:
Dung removing machine for the removal of the dung from underneath the pens of the fur animals at fur farms. The dung removing machine comprises a dung-collector-conveyor part (1) placed transversely to the running direction and operating at the level of the base to be cleaned, the said collector-conveyor being fitted so as to feed the dung collected from the base to the transfer conveyor (2). By means of the transfer conveyor (2), the dung can be guided onto a dung collector wagon (3) constituting a part of the dung removing machine. Both the collector-conveyor part (1) and the transfer conveyor (2) are fitted as one entire unit so as to be shifted in the horizontal direction perpendicularly to the direction of running of the dung removing machine. The collector-conveyor part (1) consists of a screw conveyor (5) whose rear part, viewed in the direction of running, is protected by a plowing wing (4), the end portion of the said screw conveyor, viewed in the direction of feeding, being surrounded by a feeder pipe (6) passing to the transfer conveyor.
Abstract:
Die Erfindung betrifft eine Abstreifvorrichtung zum Abstreifen von mitgeführtem Material von einer bewegten Werkzeugoberfläche eines Werkzeugs einer land- oder forstwirtschaftlichen Maschine, insbesondere einer Scharscheibe einer Scheibensäschar, wobei die Abstreifvorrichtung einen zumindest bereichsweise federelastisch ausgebildeten Grundkörper aufweist, mit dem zumindest eine Abstreifkante oder zumindest eine Abstreiffläche der Abstreifvorrichtung an die Werkzeugoberfläche des an der Abstreifvorrichtung vorbeigeführten Werkzeugs andrückbar ist. Dabei ist es vorgesehen, dass die Abstreifkante oder die Abstreiffläche aus wenigstens einem Verschleißschutzelement gebildet ist, welches durch eine Schweißverbindung mit einer zur Werkzeugoberfläche hin ausgerichteten Oberfläche des Grundkörpers der Abstreifvorrichtung verbunden ist. Die Abstreifvorrichtung zeichnet sich durch einen geringen Verschleiß aus.
