Title: Engrais organique contenant du compost
Inventor: DINEL HENRI
IPC: C05F11/04
Filed: 2000-06-27
Abstract: L'invention concerne un procédé destiné à convertir un matériau organique à base de compost, produit selon des techniques optimisées de traitement de compost, en un engrais organique pur destiné à un usage agronomique ou autre, notamment au marché croissant des aliments biologiques. Il est essentiel de n'utiliser que des déchets organiques compatibles, certifiés d'origine organique, dans l'étape de traitement du compost. Dans la première étape, on traite la matière brute organique pour obtenir du compost, à l'aide de procédés classiques optimisés, puis on tamise le compost obtenu pour éliminer toutes les particules dont la taille est approximativement d'un centimètre, ou plus. On recycle ce matériau brut dans le procédé de traitement du compost. Dans la seconde étape, on tamise encore le matériau dont le diamètre est inférieur à un centimètre, afin de séparer les particules fines de compost dont la dimension est d'un millimètre ou moins, une proportion importante des particules devant se situer en dessous de 150 microns. On rejette les particules dont la dimension se situe entre 1 mm et 1 cm, et on peut les utiliser à d'autres fins. Dans la troisième étape, on compacte les particules fines de compost à une pression de l'ordre de 2000 à 6000 psi, afin de former des granulés d'engrais organique pur possédant une densité adéquate, de façon que les éléments nutritifs soient libérés dans un milieu de culture, ou dans le substrat végétal, à une vitesse de libération appropriée à une croissance végétale optimale. Le processus de compression lie les fines particules ensemble et aide à la libération échelonnée des éléments nutritifs, à partir du granulé d'engrais organique pur. On peut répandre ces granulés d'engrais organique pur sur des champs de culture, des jardins maraîchers, et analogue, de manière classique.

Inventor: SCHNEIDER JOSEF
IPC: B41C1/10
Filed: 1989-11-08
Abstract: To apply a printed image on a printing form, a transfer tape is passed under a recording head, the transfer tape receiving, upon application of energy to the recording head, substance particles which change the surface of the printing form to have, respectively, ink accepting and ink repellent surface areas or, respectively, to fill the cells of a gravure cylinder, the transfer tape then being applied against the printing form and the substance particles  therefrom being transferred to the printing form under influence of heat, or other energy, e.g. electrostatic or electromagnetic.  Recording on the transfer tape, under control of an electronic control unit, can be carried out on a point-by-point or line-by-line basis at a recording speed which is slow with respect to the speed of operation of the reproducing head applying the substance particles to the printed form, so that information can be stored on the tape while a previously prepared printing form can print on the substrate.  The information can be erased from the printing form by melting off the substance particles, after cleaning of residual ink, and wiping, blotting or blowing off the molten particles.

Patent CA-2016319-A1 (CA)
Title: Power tongs
Inventor: FEIGEL KURT R JR
IPC: E21B19/16
Filed: 1990-05-08
Abstract: A power tong includes a frame having arcuate front portions defining a throat, a cage plate assembly mounted on the frame for rotation about a central axis and a ring gear also mounted on the frame for rotation about the axis. The throat receives the pipe to be rotated, and the cage plate and ring gear include die means for gripping the pipe. The ring gear and cage plate cooperate to rotate the pipe within the frame, which remains stationary. The design of the power tong is such that the arcuate front portions of the frame are more flexible than the cage plate assembly and ring gear combination, and strain is primarily taken up by the ring gear and cage plate. In addition, the cage plate and ring gear are sufficiently rigid such that they may not flex to a degree that teeth on the ring gear flex more than the backlash in the gear train that drives the ring gear.      Finally, the ring gear includes offset cam surfaces, which help to ensure that the pipe is centrally located within the ring gear, the cam surfaces having identical elliptical sections.

Title: Electronic article surveillance tag and method of deactivating tags
Inventor: BENGE EUGENE S
IPC: H03K17/945
Filed: 1990-07-31
Abstract: A deactivatable tag useable with an electronic article surveillance system and method of making such a tag. The tag includes a resonant circuit and a provision for promoting the permanent deactivation of the tag. The solution according to the present invention has been to render the deactivator more difficult to operate. A higher level of excess energy is applied to the resonant circuit before the breakdown material breaks down. This higher level of energy in the resonant circuit is applied to the improved deactivator and operates the deactivator much more completely. This arrangement promotes permanent deactivation of the resonant circuit to prevent the resonant circuit from becoming active again or "coming back to life" as time passes. The deactivator adjacent the resonant circuit can include a vacuum metalized conductive coating.
