IPC: E02D29/02
Filed: 2003-09-12
Abstract: A precast concrete building element and structure constructed from such elements, the elements being designed so that either face of the element can be used in the design of the construction of retaining walls, foundations, posts or other structures, wherein one face of the element gives the appearance of a dual vertical octagon shape, and the other face of the element is vertically flat faced, with a 45 degree vertically angled corner on each end of the element. Thus, the overall wall or structure gives the appearance of repeating vertical part octagonal shapes. Through various configurations of such a design, arrangements of elements to form structures which have an internal angle of 45, 90 and 135 degrees are possible. The structure can be designed so that it can be stacked straight up, in that each element comprising the structure has a groove or channel on a bottom of the element, which internally extends a length of the element, and a top surface of the element has two button shaped protrusions thereon. The protrusions are designed to allow each element to lock or connect into the groove or channel of another element placed thereon.

Title: Prechauffe eau solaire et bois
Inventor: LABRECQUE MARCEL
IPC: F24J2/04
Filed: 2003-12-31
Abstract: Il existe déjà des serpentins pour poêle à bois mais ils contiennent un minimum de danger par exemple: Vu que le circuit d'eau passe dans le feu et que la température devient très élevée, il peut se produire une explosion dans le cas d'une défectuosité de la valve de sécurité ou d'un autre équipement et/ou causer des brûlures .Ainsi l'eau ne peut être utilisée directement du circuit, à des fins de lavage.  Aussi il existe déjà des chauffe eau solaire qui demeurent relativement coûteux ne pouvant ainsi être accessibles aux citoyens à budget moyen ou faible. La présente invention élimine ces risques et inconvénients. Simplifiée au maximum et peu coûteuse, la dite invention a été fabriquée pour préchauffer et emmagasiner dans une réserve qui dessert par la suite le chauffe eau électrique, diminuant ainsi la consommation d'électricité. Constitué de deux capteurs de chaleur dont un solaire et l'autre la chaleur perdue d'un chauffage en général au bois,le système est calibré pour que la température de l'eau ne dépasse pas (110 degré F.) environ et qu'elle puisse être utilisée à des fins ménagères telle le rinçage,le lavage en général.

Inventor: POLING KIM L
IPC: B23Q7/10
Filed: 2004-09-15
Abstract: An improved mechanism feeds loops or ties into clip attachment apparatus such as a clipper. The loops preferably have tie portions, the carrier may be a tape, and the loops should be in substantially equidistant series on the carrier. The carrier passes around rollers and a dancer, and along a stationary plate. Strip plates are preferably pivotally mounted adjacent the stationary plate. A loop and carrier drive indexes the loops on the carrier toward the clip attachment apparatus. A strip plate drive pivots the strip plates to and from positions in which the strip plates strip a loop adjacent the clip attachment apparatus at least partially from the carrier. The strip plate drive pivots the strip plates to catch the loop adjacent the clip attachment apparatus between the strip plates and pull the loop at least partially from the carrier. The strip plate drive pivots a preferred upper strip plate to catch the loop that is adjacent the clip attachment apparatus between the upper strip plate and a preferred lower strip plate, to pull the tie portion of the loop from the carrier. The loop and carrier drive indexes the carrier in the area of the strip plates a distance corresponding to one loop following each action of the strip plate drive. A loop brake brakes the carrier to allow the strip plates to better strip the loop at least partially from the carrier, the loop brake braking the carrier while the strip plates do the stripping.

Abstract: A method and mechanism is disclosed for implementing storage and retrieval of data in a computing system. Data compression is performed on stored data by reducing or eliminating duplicated values in a database block. Rather than writing the duplicated data values to the data storage unit, the on-disk data is configured to reference a copy of each duplicated data value stored in a symbol table. A method and mechanism of improving performance of database query language statements is also disclosed. Information describing data duplication within a data block is maintained. In one embodiment, the data duplication information is used to reduce number of predicate evaluations on data in the data block when a database query language statement is received against the data in the data block. In another embodiment, the data duplication information is used to reduce amount of data accessed by a database query language statement.

Abstract: The invention relates to a locking and unlocking device for vehicle doors, in particular swinging sliding doors for rail vehicles, having the features of the preamble of patent claim 1. Taking the disadvantages of the known prior art as a starting point, a locking and unlocking device is to be provided which requires a small amount of expenditure on manufacture and mounting, and ensures reliable locking and is suitable for different designs of door. As a solution it is proposed that at least one engagement element be provided on the inside of the door leaf or of the door at a defined distance from the inside of the door, and a spring-loaded spagnolet 12 be arranged horizontally opposite the latter on the inside of the door frame. The spagnolet 12 has a semicircular or claw-shaped recess 12d and a locking section 12b which projects laterally beyond the recess 12d. On the inside of the door frame, a locking element 13 is movably guided and is connected to at least one rod 14 which can be moved in the vertical direction. During the closing movement of the door leaves or of the door, the engagement element engages with the recess 12d of the spagnolet 12, and as a result of the pressing movement of the door leaf or of the door the spagnolet 12 swings with its locking section 12b in the direction of the center of the door opening and assumes a position extending parallel to the door leaf and is locked in this position by a movement of the locking element 13 which is triggered in the vertical direction.

Title: Human power amplifier for lifting load including apparatus for preventing slack in lifting cable
Inventor: KAZEROONI HOMAYOON
IPC: G01L5/22
Filed: 2000-02-17
Abstract: A human power amplifier assist device (10) includes an end-effector (14) that is grasped by a human operator and applied to a load (25). The end-effector (14) is suspended, via a line (13), from a take-up pulley (11), winch or drum that is driven by an actuator (12) to lift or lower the load (25). The end-effector (14) includes a force sensor (31) that measures the vertical force imposed on the end-effector (14) by the operator and delivers a signal to a controller (20). The controller (20) and actuator (12) are structured in such a way that a predetermined percentage of the force necessary to lift or lower the load (25) is applied by the actuator (12), with the remaining force being supplied by the operator. The load (25) thus feels lighter to the operator, but the operator does not lose the sense of lifting against both the gravitation and inertial forces originating in the load (25).
