Title: Briquette d'allumage
Inventor: LABONTE NELSON
IPC: C10L11/04
Filed: 1994-02-01
Granted: 1999-10-12
Abstract: Dans les articles servant à allumer un feu, la pratique courante était de se servir de journaux, d'écorce de bouleaux, de bois fendu en bois d'allumage, additionné souvent d'un activant pétrolier. On sait que l'efficacité de combustion des dispositifs d'allumage déjà connus résulte non seulement de leur constitution mais également de la façon dont ceux-ci sont disposés sur la substance à allumer afin de permettre un jeu d'air pour l'entretien de la flamme. Dans la présente invention, le dispositif d'allumage qui est un allume-feu est composé de plusieurs feuilles de carton ondulé, superposées les unes sur les autres et retenues entr'elles par de la colle pour ainsi former une briquette, laquelle est ensuite imprégnée de paraffine, de cire ou de gras animal ou végétal. L'utilité et la distinction de la présente invention résulte du fait que la disposition de ce dispositif d'allumage sur la substance à allumer importe peu puisque le jeu d'air est permis grâce à la constitution même du dispositif d'allumage. En effet, les alvéoles du carton ondulé imprégnées permettent ce jeu d'air et par conséquent, procure une flamme soutenue. Il permet un allumage rapide et soutenu, dans un minimum d'espace. Egalement, le dispositif d'allumage peut occasionnellement être muni d'allumettes paraffinées. Dans ce cas, il s'agit d'un allume-feu de survie qui permet qu'une allumette soit toujours à la disposition de son utilisateur.

Abstract: A mixing chamber  (3)  and a gas inlet chamber (5)  are concentrically arranged in a closed housing  (1)  and divided from one another by a tubular partition wall (7) provided with micropores.  A flow of a liquid, foamable medium is introduced by a pump  (21)  axially into the mixing chamber (3).  At the same time, air produced by a compressor (23) is introduced via a housing inlet  (17) into the gas inlet chamber (5) under such a pressure that the air can penetrate through the micropores  in the tubular partition wall (7) into the mixing chamber (3). The partition wall (7) surrounding the mixing chamber and the peripheral wall (9) are replaceably mounted between two flanges (11 and 12).  The cross-sectional profile of the axial inlet and outlet (15 and 16) is matched to the cylindrical cross-section of the mixing chamber (3) so that in operation a laminar flow of the foam mixture substantially parallel to the axis occurs through the mixing chamber (3).

Title: Insert molded article, and apparatus and method for producing the insert molded article
Inventor: YAMAZAKI SEIICHI
IPC: B29C45/14
Filed: 1993-12-27
Granted: 2002-06-11
Abstract: The present invention relates to a method and apparatus for producing insert molded articles. The method is comprised of the steps of preforming a patterned insert material clamped at end parts thereof by a clamping unit into a predetermined shape corresponding to the shape of a cavity formation face of a male die or a female die of an injection molding die by a preforming unit. The insert material is then trimmed to remove the unnecessary portion of the preformed material. A trimming unit accomplishes this step. The trimming is done so as not to allow the insert material to project from the peripheral edge of the surface of a three dimensional molded article to be formed of molding resin. The preformed and trimmed insert material is then set at the cavity formation face of the male or female die of the injection molding die.      The male and female dies are then clamped to form a cavity by the cavity formation faces. Resin is then injected into the cavity to produce the article. The article is taken from the injection molding die after the molding resin is cooled and softened. At the preforming time, a preforming die having a projecting part corresponding in shape to the cavity formation face of the injection molding die is used, so that the patterned insert material can be preformed corresponding to the shape of the projecting part of the preforming die.      Moreover, prior to the preforming of the patterned inset material, the patterned insert material can be heated and softened after, before, or while being held in touch with the top face of the projecting part of the preforming die, so that the patterned insert material is preformed to trace the projecting part of the preforming die.

Abstract: A water treatment tank for separating particles from water, has a separation chamber with at least one set of inclined parallel plates with a slot between each pair of adjacent plates for substantial horizontal flow of water between the plates A sludge chamber is located beneath the separation chamber for collecting sludge including the particles separated from the water during passage of the water through the separation chamber. An inlet chamber on one side of the separation chamber introduces the substantially horizontal flow of water into the separation chamber, and an outlet chamber on an opposite side of the separation chamber receives the flow in the substantially horizontal direction from the separation chamber. The outlet chamber is located above and communicates with the sludge chamber and further separates particles from the water in the outlet chamber, the particles descending into the sludge chamber. An outlet channel is located in an upper portion of the outlet chamber and has an outlet weir on each side of the outlet channel. The outlet channel and outlet weirs extend for the length of the separation chamber, and a surface layer of water in the outlet chamber overflows the outlet weirs into the outlet channel to create an outflow. An overflow rate of water per unit length of the outlet weirs is minimized for a given tank flow rate. In another embodiment, a gas distribution pipe is adjacent the inclined plates and configured to emit gas bubbles during a plate rinsing cycle to dislodge particles trapped between the plates.
