摘要:
A process for forming an easy open lid comprising a central panel having a score strip with a score thereon, a crimping edge and a ring enabling the lid to be opened by perforation of the score. The score on the lid is formed from a metal lid outline supported by an anvil by displacing a punch of angle alpha thereover and causing an asymmetrical flow of metal between the punch and the anvil during the displacing. This reduces the risk of crack formation in the metal at the bottom portion of the score or beneath the score.

A prefabricated three-dimensional truss structure for a bridge, or the like, the truss formed from bars arranged to define triangular or rectangular patterns. The bars are formed from prestressed, high-strength concrete that are connected at their ends with assembly blocks that are prestressed, the prestress being preferably provided by the cables that prestress the bars, and which terminate at the blocks. A plurality of such unit trusses can be assembled to provide a truss structure for a bridge span, and the trusses can assume a wide variety of configurations.
摘要:
A machine for processing foodstuffs comprising a tank whose position on a support base is determined by a finger projecting from the tank and engaged in a socket in the support base. The support base is part of a housing in which is disposed a drive motor driving a shaft vertically projecting in the tank and supporting appropriate cutters. The tank is covered by a removable cover, and interlocks are provided for preventing the drive motor from being started unless the tank is correctly positioned, the removable cover is locked over the tank and appropriately positioned relative to the tank.

This invention relates to a production of a structure by means of arch stones. The arch stones comprise series of mixed steel-concrete arch stones (V.sub.M), each comprising a metal frame of steel integral with an upper concrete slab, these series being separated by interposed concrete arch stones or sections, (V.sub.B), the assembly of the arch stones being reinforced longitudinally by prestress cables which penetrate the metal frames and are attached at their ends to the concrete arch stones. This invention may be applied to bridge floors and similar structures.

The baby car seat track system comprises a track, a seat adapter, and a child seat. The baby car seat track system may be operable to couple the child seat to a vehicle seat in a vehicle. The track may be embedded within the vehicle seat running laterally across the vehicle seat and accessible via a crevice of the vehicle seat. The seat adapter may couple the child seat to the track such that the child seat may be repositioned laterally on the vehicle seat and may rotate around a vertical axis. The baby car seat track system may be adapted to make a child more accessible to a user by repositioning and rotating the child seat within the vehicle.

A method for detecting matching profiles in an environment of wireless terminals each having a short range communications capability, comprises the steps of: —generating profiles respectively belonging to a plurality of users, —storing said profiles in wireless terminals associated with said user, —when a pair of terminals become in range with each other, automatically establishing a short range bidirectional communications channel therebetween, —through this channel, transmitting the profiles stored in each terminal to the other terminal, performing a matching test between said received profiles and other profiles previously stored in the terminal, and—when a matching between profiles is determined by a terminal, providing profile matching information so that the users to which said profiles belong can be put in connection with each other. The present invention also provides other related communication methods, as well as a terminal and a system for implementing the methods.
摘要:
A system and method for forming an extruded jacket over an elongated object is provided. The system includes a quantity of heated jacketing material and at least one die having an entry side and an exit side, the entry side proximate to the quantity of heated jacketing material, wherein the quantity of heated jacketing material is extruded through the at least one die. A heating device is located proximate to the exit side of the at least one die, wherein the heating device positioned to maintain the extruded quantity of heated jacketing material in a heated state. A wrapping device is positioned to rotate the elongated object, wherein the extruded quantity of heated jacketing material is wrapped around at least a portion of the elongated object.

Cementation slurries well suited for encasing reinforcing elements therefor, for example prestressed steel cable, while reducing the risk of embrittlement thereof, contain from about 1.5% to 3% by weight of homogenizing and exudation-reducing hydrophilic particulates (e.g., precipitated silica particles) that are inert in respect of liquids, have a specific surface area of greater than about 200 m.sup.2 /g and which are fragmentable during mixing and/or injection into multiple fragments having particle sizes ranging from about 5 to 300 nanometers.
