Title: Siding production line cooling apparatus and method
Inventor: SZABO ROBERT
IPC: B29C48/32
Filed: 2004-02-11
Abstract: A production line for the manufacture of strips of vinyl siding comprises an extruder extruding a strip of hot plastic material, such as vinyl. Next, an embosser supplies a decorative pattern to the heated strip. A cooling apparatus receives the heated strip and immerses the strip in a water bath to lower the temperature to a selected temperature range. The material, now reduced in temperature, is then passed to a former having dies creating joining runs in the cooled, embossed siding strip. Finally the strip runs through a final cooling tank which chills the strip to harden the joining runs created by the former. The cooling apparatus consists of a water bath tank with entry and exit guides for the strip, which are mounted above the level of the water in the water bath tank. A third guide, such as a roller, is positioned between the entry and exit guides and is selectively extendable in depth into the water bath so as to selectively extend the strip deeper into the water bath and thereby vary the dwell time of the strip to regulate cooling.

Title: Crinkling device
Inventor: SUOLAHTI YRJO
IPC: B65B11/04
Filed: 2004-03-11
Abstract: The invention relates to a crinkling device comprising a slide rod (16), to which a second crinkling element (15) is fastened. The slide rod is guided in a frame (2) so as to be movable in a substantially vertical direction between a lower position (L), in which the second crinkling element (15) is out of contact with the lower edge (4) of a foil web (1), and an upper position (U), in which the second crinkling element (15) deflects the lower edge (4) of the foil web (1) upwards so as to crinkle it. The slide rod returns to the lower position (L) when not exposed to a force acting in the upward direction. The device further comprises first coupling means (17 1, 18 1) for forming a releasable coupling between the slide rod (16) and a first drive element portion (8) when the drive element (7) is running in a first direction (11) to move the second crinkling element (15) to the upper position (U). Second coupling means (17 2, 18 2) are provided to form a releasable coupling between the slide rod (16) and a second drive element portion (9) when the drive element (7) is running in a second direction (12) to move the second crinkling element (15) to the upper position (U). By driving the drive element (7) in the first running direction (11), the foil web (1) can only be crinkled from its lower edge (4). By driving the drive element (7) in the second running direction (12), the foil web (1) can be crinkled optionally either from the upper edge (3) by a first crinkling element (14) without crinkling the lower edge (4) or from the upper edge (3) and the lower edge (4) simultaneously.

IPC: C12N15/01
Filed: 2002-09-13
Abstract: La présente invention concerne une nouvelle utilisation d'une chambre de diffusion à l'intérieur de laquelle peuvent être isolés des microorganismes qui étaient jusque là <= non cultivables >=. Plutôt que de tenter de reproduire l'environnement naturel d'un microorganisme inconnu, le procédé de l'invention choisit d'exposer des microorganismes en division à tous les composants de leur environnement d'origine tout en contenant simultanément les colonies obtenues afin de pouvoir les isoler. Le procédé précité tire parti du fait que la prédominance de microorganismes difficiles à cultiver ne forme pas de colonies visibles à l'oeil nu. C'est pourquoi ces organismes doivent être isolés sous un microscope composé, sous la forme de <= microcolonies >=. L'invention se rapporteen outre à des procédés qui permettent d'isoler de nouveaux microorganismes capables de croître dans un milieu artificiel uniquement en co-culture avec un microorganisme compagnon.

Inventor: LAKSHMAN GURUNATHAN
IPC: C02F11/145
Filed: 2002-07-26
Abstract: The invention relates to a method of treating manure such that odour from th e manure is significantly reduced or eliminated and producing therefrom recyclable water, value-added biosolids and ammonia. Specifically, the manur e is combined with lime at high pH. The material is mixed under negative pressure and the basic conditions cause ammonia to be evolved from the manur e which is then drawn off and recovered. A coagulating agent is then added whi ch further promotes floc formation within the manure. Following further mixing, flocs are separated from the liquid portion. A struvite-promoting chemical a nd a coagulant are then added to the liquid portion which causes further floc formation, and the flocs are again separated from the substantially clear liquid. It is of note that as a result of this process, the solids are highl y hydrophobic and dry very quickly. It is of further note that solids isolated from either step can be combined and sold, for example, as fertilizer, as discussed below. The clear liquid can be used, for example, in barn washes o r for horticultural watering.
