Title: Water circulation apparatus and method
Inventor: VEGA SALINAS DANIEL EDUARDO
IPC: A01K61/60
Filed: 2001-07-04
Abstract: An apparatus and method for conditioning water in open fish breeding cages, which can solve the problems of "bloom of harmful seaweed" and the "lack of dissolved oxygen concentration in the water". The apparatus includes a tube having adjustable open upper and lower ends and an impeller for drawing a major water flow in either direction through the tube. To solve the "bloom of harmful seaweed" the apparatus draws water upward from deeper water with low algae concentration to the bloom zone, dissolving and moving the harmful seaweed far away from the cages. To solve the "lack of dissolved oxygen concentration" the apparatus draws water downward from the surface water having high concentrations of dissolved oxygen to deeper water with low concentrations of dissolved oxygen, increasing the dissolved oxygen concentration in the middle and the bottom of the cages, where the biggest oxygen consuming fish concentration are located.

Abstract: A fiber optic gyroscope having polarization error-correcting modulation.  Polarization errors originate from the interference of primary waves and secondary cross-coupled waves. Although these error signals are very difficult to remove modulation signals may be applied to the integrated optics chip that minimize the total error over a period of time. By providing distinct but inter-related modulation signals to opposing inputs of the sensing coil, the various polarization errors can be averaged to zero over the period of the modulation signals.

Abstract: A multiple-chain trenching machine comprises a prime mover with a trenching head assembly operably connected thereto. The trenching head may be raised, lowered, and/or pivoted relative to the prime mover, and comprises: a) a frame operably connected to the prime mover at a proximal end; b) one or more pairs of proximal and distal primary sprockets mounted on the frame; c) a primary endless-chain digging assembly engaged with and circulating around each pair of primary sprockets; d) one or more pairs of proximal and distal secondary sprockets mounted on the frame; e) a secondary endless-chain digging assembly engaged with and circulating around each pair of secondary sprockets. The primary chains are substantially wider than the secondary chains, and the diameters and positions of the sprockets may be such that each of the secondary chains cuts more deeply into the ground formation than the primary chains, thereby producing a narrow relief slot corresponding to each secondary chain. The primary chains are driven in a forward chain direction, so that disintegrated material is removed from the trench by the motion of the primary chains. The secondary chains may be driven in a forward or a reverse chain direction at about one to eight times the linear speed of the primary chains. If operated in the reverse chain direction, the disintegrated material produced by the secondary chains may be deposited within the trench by the motion of the secondary chains. The material thus deposited may serve as a support bed for whatever structure is to be subsequently placed within the trench.

Abstract: A multi-leaved social expression card has first and second leaves joined together along a first score line and foldable into overlying relationship with each other to form a social expression card. The first and second leaves can have social expressions thereon identifying the sending situation for the card. A flap is joined to the first leaf along a perforated/score line, and is foldable into overlying adjacent relationship with the back of the second leaf when the first and second leaf are folded together. The said flap includes an adhesive structure which adhesively secures the flap to the back of the second leaf to form a substitute envelope. When displayed the leaves will be folded such that the inside of the first leaf, where the image or social greeting is displayed, will face outward. The first leaf can then be folded in to be adjacent with the second leaf and the flap can then be folded over the second leaf. The adhesive structure on the flap can then be activated to seal the flap to the back of the second leaf for mailing or otherwise distributing the social expression card.

Abstract: A scotch yoke type fluid device in which the pistons (32) are decoupled from each other and provides each piston (32) with its own pair of sliding surfaces (30) and its own slider (18). The sliding surface (30) of each piston are disposed on the same side of the big end bearing (16) of the crank (12). The main axis (14) of the crank (12) is movable along a path such that the pistons are neither substantially retarded nor advanced. The effective centre of mass of the crank, piston and slider remains stationary relative to the crank axis. Each piston includes a guide means (2030) for constraining the piston to move along the piston axis, the guide means located transversely of the sliding surfaces (30) and engage guides rigidly mounted on the crankcase. An intermediate member may interconnect the piston and the slides with a means for adjusting the position of the intermediate member in order to change the compression ratio of the device. For a device having opposed pistons, the yoke (6060) attached to the two pistons is split into two parts (6062a, 6062b) releasably held together.

Title: A system and method for providing immediate visual response to user input at a client system
Inventor: PANASYUK ANATOLIY
IPC: G06F15/00
Filed: 2000-07-20
Abstract: A method and an apparatus for reducing perceived visual response to user input at a client node are described. The client node remotely executes an application program on a server node wherein all execution of the application program occurs on the server node. The client node (10) transmits user-provided input to the server node ( 14), and the user-provided input elicits a response from the server node that is transmitted back to the client for display. The client node receives the user input to be transmitted to the server node. The client node can obtain the user input (34) through a keyboard or a pointing device. In response to the user input, the client node produces a prediction (30) of a server response to the user input. The client node then displays the prediction (22). The display of the prediction provides the client user with a faster visual response to the user input than could be obtained from the server node. Upon receiving the server response, the client node displays the server response, overwriting the prediction.
