Title: Method for production of sodium bicarbonate, sodium carbonate and ammonium sulfate from sodium sulfate
Inventor: KRESNYAK STEVE
IPC: C01D7/12
Filed: 1996-06-21
Abstract: A process for producing sodium bicarbonate and sodium carbonate. The process includes reacting within a reactor sodium sulfate in aqueous solution with ammonia and carbon dioxide to precipitate sodium bicarbonate and form a first mother liquor. The sodium bicarbonate is separated and dried to produce sodium bicarbonate product. Alternatively, the sodium bicarbonate may be calcined to convert it to sodium carbonate. The first mother liquor may be evaporated to precipitate unreacted sodium sulfate, with the formation of a second mother liquor. The second mother liquor may be cooled to precipitate a double salt of sodium sulfate/ammonium sulfate and water. A third mother liquor is formed from this process. The latter-mentioned liquor from the precipitation of the double salt is evaporated to precipitate a substantial pure ammonium sulfate in a purity of greater than approximately 75 wt %. A fourth mother liquor is formed. The double salt is added to the first mother liquor from the precipitation of sodium bicarbonate prior to the evaporation step and the fourth mother liquor is added to the second mother liquor from the evaporation to precipitate unreacted sodium sulfate.

Abstract: Boîte mise en forme par pliage d'une découpe plate en matériau élastique mince à lignes de plissement. Cette boîte est de forme générale polyédrique et elle présente un bord (la ligne de fermeture) (25) au niveau duquel deux faces (les faces de fermeture) (17, 18) se réunissent tout en pouvant être séparées l'une de l'autre. Lorsque l'on pousse l'un vers l'autre (en 26) les sommets situés aux extrémités de cette ligne, lesdites faces s'écartent de manière élastique l'une de l'autre (en 27) au niveau de cette ligne, afin d'ouvrir l'accès à l'intérieur de la boîte. La ligne de fermeture peut être scellée par des moyens de scellement provisoire (par exemple un ruban adhésif décollable ou une languette déchirable de fermeture (37-39)). Il peut y avoir un recouvrement de l'une des faces de fermeture sur l'autre (Figs. 3A-3C), ce qui assure une fermeture plus résistante. Dans un premier temps, ce recouvrement peut être plié vers l'intérieur de manière à former un "paquet coussin" (Fig. 4). La boîte peut présenter différentes formes; de préférence, elle a une base plate et la ligne de fermeture s'étend au-dessus de la base et parallèlement à celle-ci. Une forme élémentaire est un prisme triangulaire couché (Figs. 2A & 2B); une autre est composée d'une base rectangulaire sur laquelle se dressent quatre faces latérales verticales dont les extrémités supérieures sont inclinées en zigzag, la boîte étant dans ce cas fermée par deux faces supérieures triangulaires inclinées, et les faces latérales étant trapézoïdales (Fig. 5) ou triangulaires (Fig. 6). Les boîtes peuvent s'emboîter les unes dans les autres à l'état partiellement mis en forme, les bases étant ouvertes. On peut stocker les boîtes à l'état aplati, et leurs bases se mettent en forme automatiquement lors de l'ouverture.

Abstract: Le sécheur de cette invention emploie une enceinte à dépression placée entre deux rouleaux sécheurs (26, 28) chauffés et au-dessous de ceux-ci. Cette enceinte, comportant deux côtés et une face supérieure qui recouvre deux cylindres de renvoi cannelés (110, 114), régule le flux d'air s'écoulant entre les rouleaux sécheurs et au-dessous d'eux. La bande de papier continue en appui sur la toile de séchage passe du premier rouleau sécheur autour des cylindres de renvoi pour se rendre jusqu'au second rouleau sécheur. La toile de séchage ferme hermétiquement l'enceinte à dépression d'où l'air est prélevé. La présence des deux cylindres dans l'enceinte fait qu'une plus grand partie des faces de rouleau sécheur reste en contact avec la bande tandis que, grâce à l'enceinte, se crée une dépression sur les deux cylindres et les trois tronçons de bande qui ne sont pas sur les cylindres, et ce, en ne faisant appel qu'à une seule source de dépression, ce qui permet de réaliser d'importants gains de coûts.

Inventor: AOKI SHINJI
IPC: F24J3/00
Filed: 1997-08-20
Abstract: According  to  the present  invention,  in  a  heating apparatus having a viscous heater using viscous fluid for heating cooling water, when an engine rotational speed is lower than a set rotational speed relative to a temperature of viscous fluid, a viscous clutch is turned on to transmit a rotational driving force of the engine to a rotor of the viscous heater.  In this way, a shearing force is applied to the viscous fluid in the heat-generating chamber,  and the circulating cooling water is heated by generated heat of the viscous fluid to improve the heating capacity.  When the engine rotational  speed  is  higher than the set  rotational  speed relative to a temperature of viscous fluid, a viscous clutch is not turned on.  Therefore, the rotational driving force of the engine is not transmitted to the rotor of the viscous heater, so that the shearing force is not applied to the viscous fluid to prevent the oil temperature of the viscous  fluid from increasing excessively higher than 200 °C.

Patent CA-2213062-A1 (CA)
Inventor: MEYER STEPHEN T
IPC: F16L31/00
Filed: 1997-08-15
Abstract: A connector for joining together in an end-to-end arrangement two lengths of wire-wound flexible hose includes a unitary, molded plastic hollow body which is internally threaded with two series of threads separated by an interior abutment rib.  A first series of threads are cooperatively arranged to receive one of the two lengths of flexible hose.  The other series of internal threads is cooperatively arranged to threadedly receive the other length of flexible hose.  As the flexible hose is threaded into the interior of the connector, the molded threads on the interior of the hollow body control the pitch of the wire-wound flexible hose in order to ensure secure threaded engagement.  In a related embodiment, the internally-threaded connector portion is combined with a protector portion on one side and a conduit- connecting portion on the opposite side.  These three portions are joined as a unitary molded member.  The conduit- connecting portion is designed to press onto a dryer exhaust pipe for attaching the connector to the pipe with a secure interference fit.  The protector portion serves as a spacer to control the amount of clearance between the rear panel of the dryer and an adjacent vertical wall.  The length of the protector portion is sufficient to allow the flexible hose to make a 90 degree bend without being pinched or otherwise restricted as could occur if the dryer is pushed too close to the vertical wall.

Abstract: A radio-based, Electro-Pneumatic (EP) rail car braking system supports both End-of-Train (EOT) and Distributed Power Control (DPC) communication systems. The EP rail car braking system operates within existing frequency allocations and meets operational reliability needs by adopting a hybrid, two-band communications scheme. The EP rail car braking system uses a broadcast band for transmitting commands to all cars in the train. Selected cars spaced through the train are designated as repeaters, and a predetermined number of cars are assigned to each repeater for forming a group of cars that act as a Local Area Network (LAN). The cars in a group communicate with each other using a low power, spread spectrum band. In response to a command broadcast by a lead locomotive, cars in a group act on the command and transmit status information to their repeater car. The repeater car, in turn, sends back status messages to the lead locomotive on the broadcast band based on consolidation of data received from the cars in its group.
