Abstract: A soft-sided roller supported luggage or case with telescopic handle rods is provided with housings that secure to at least two of the top wall, end wall, or rear wall of the case. In one embodiment the housings are secured to all three of the top, rear, and end walls. The housings extend less than the full length of the case leaving considerable extra storage space within the case and,for external housings, reducing the chance of bending or other damage to the housings. The rigid connection between the housings and at least at two walls and preferably three walls provides sufficient support for holding the weight ofthe case with the handle rods extended. The housings on an internal case are preferably located at or close to the corners of the rear and end walls of the case to again increase the unobstructed storage space in the case.

Granted: 1998-10-06
Abstract: In a method and a device for sewage purification, sewage is purified by continuously passing it through several stages of treatment, wherein the passage of sewage is regulated by a process control device and is monitored by sensors.    Treatment ensues in physical processing stages, pre-flotation stages, two-step biological clarification stages and one post-flotation stage.  The pre-flotation stages as well as the biological clarification stages are each provided with gas-water mixers, and the pre-flotation stages, the biological clarification stages and the post-flotation stage are provided with solid foam separators having outlet channels.    Clear water from a clear water overflow basin is supplied to the individual stages through the gas-water mixers and through a clear water return pipe.  It is also possible to provide chemical treatment prior to biological clearing, to provide clear water recycling for additional treatment, and to provide solids treatment and a reduction stage.  An aquatritor, a bioreactor and a four chamber system are also provided.  This method is also suitable for use in a portable device having a compact construction.

Title: Method for heating hydrocarbon contaminated soils and removal of volatile hydrocarbons
Inventor: IGNASIAK TERESA
IPC: B09C1/02
Filed: 1997-06-17
Granted: 2003-05-20
Abstract: An improved method for heating the aqueous slurries of soils contaminated with tarry/oily organics and volatile compounds. The method includes the steps of heating the slurry (containing inorganic and carbonaceous solids below 1/8 inch) with atmospheric pressure steam in a specially designed slurry heater(s), contacting the hot (95-99°C) slurry with the contaminated feed soil (top size 5 inch) in a hydraulic feeder, processing the resultant slurry in a tumbler at temperatures up to 90°C, separating the -1/8 inch solids from the slurry exiting the tumbler and recycling a portion of the -1/8 inch solids in slurry back to slurry heater(s). In order to reach the required temperature in the tumbler, the -1/8 inch slurry has to travel through the tumbler at mass flow rates 1.5-4.0 times higher as compared to those for the soil feed stream. Under such conditions, the find (-1/8 inch) components of the soil are processed under more rigorous conditions (steam, high temperature, residence time, agitation) compared to large (1/8-5.0 inch) mineral components of the soil. This results in further improvement of thermal efficiency of the process.

Title: Yaw moment control system in vehicle
Inventor: SHIBAHATA YASUJI
IPC: B60K23/04
Filed: 1997-11-12
Granted: 2002-01-08
Abstract: A yaw moment control system for a vehicle is provided to prevent the reduction of the turning performance during traveling of a vehicle at a low speed, which is designed, so that a driving force and a braking force are distributed to inner and outer wheels during turning of the vehicle in order to eliminate an over-steering tendency produced upon deceleration of the vehicle during turning thereof, thereby enhancing the stability during traveling of the vehicle at a high speed. A longitudinal acceleration Xg calculated in a longitudinal acceleration calculating circuit, a lateral acceleration Yg calculated in a lateral acceleration calculating circuit and a correcting factor Kv determined in a correcting factor determining circuit are multiplied by a control amount calculating circuit. Torque proportional to the resulting product is distributed to left and right wheels to eliminate the over-steering tendency produced upon deceleration of the vehicle during the turning thereof. When the vehicle is being decelerated and the vehicle speed V is smaller, the correcting factor Kv assumes a value smaller than 1.0, and at the other time, the correcting factor Kv assumes a value of 1Ø Therefore, when the vehicle is traveling at a low vehicle speed, an under-steering tendency can be prevented from being produced by the distribution of the torque, thereby preventing the reduction in turning performance.

Abstract: A liquid discharge head is provided which allows production of a recorded image of improved quality by controlling the speed of flow of a liquid and the distribution of the speed of flow in a flow path caused in consequence of contraction of bubbles thereby stabilizing the direction of satellites arising behind main drops of discharged liquid and, at the same time, decreasing the amount itself of the satellites. This liquid discharge head comprises a movable separation membrane capable of effecting separation between a first flow path communicating with a discharge port for discharging a liquid and a second flow path furnished with a bubble generating region for generating bubbles in the liquid by means of a heating element and a movable member opposed to the bubble generating region across the movable separation membrane and furnished in the direction of liquid discharge with a free end to guide the displacement of the movable separation membrane induced by the growth of the bubbles in the direction of the discharge port and regulate the shape of displacement of the movable separation membrane as well.

Abstract: An electrochemical fuel cell stack with improved reactant manifolding and sealing includes a pair of separator plates interposed between adjacent membrane electrode assemblies. Passageways fluidly interconnecting the anodes to a fuel manifold and interconnecting the cathodes to an oxidant manifold are formed between adjoiningnon-active surfaces of the pairs of separator plates. The passageways extend through one or more ports penetrating the thickness of one of the plates thereby fluidly connecting the manifold to the opposite active surface of that plate, and the contacted electrode. The non-active surfaces of adjoining separator plates in a fuel cell stack cooperate to provide passageways for directing both reactants from respective stack fuel and oxidant supply manifolds to the appropriate electrodes. The fuel and oxidant reactant streams passageways are fluidly isolated from each other, although they both traverse adjoining non-active surfaces of the same pair of plates. The present manifolding configuration simplifies the sealing mechanisms associated with the stack manifolds because reactant streams are not directed between the separator plates and resilient MEA seals. Coolant passages may also be conveniently provided between adjoining non-active surfaces of the pairs of separator plates.

Abstract: A combination trolley and bag to receive and hold leaves and debris cleaned from a rain gutter (eavestrough). The trolley includes a pair of rolling sheaves that ride on the outside edge of the gutter to transport leaves and debris from the initial point to the next section to be cleaned or until the bag is full. Safety flaps attached to the same shaft as sheaves work as a stopper to keep the device in place in case the sheaves slide off the gutter edge. The safety flaps spin freely to by pass any obstacle in the gutter such as brackets, holding nails, or fastening devices which secure the gutter to the roof. Two support arms, which hold and secure the bag, hinge to an up position for flat and easy storage. When lifting one of the support arms and holding handle at the bottom of the bag, emptying becomes easy. Bag size is determinate by weight of leaves and debris, so when full, can be easily lifted off the gutter edge, brought down and emptied.
