Abstract: Battery cells, battery cell units, battery modules, and battery assemblies are described. The cells of such components include a prismatic shaped cell housing including a slanted wall. Substantially planar positive and negative electrodes are arranged within the housing. The slanted wall defines a pocket within the housing between edges of the electrodes and an interior surface of the slanted wall and the pocket is configured to collect gas generated within the housing. A vent is formed on the slanted wall of the housing proximate the pocket. The vent is initially in a closed state and configured to open upon an increase in pressure within the housing to allow pressure and/or gases to leave the cell cavity through the vent. The battery cell units, battery modules, and battery assemblies may include such cells.

Abstract: A screen changer for filtering a thermoplastic material heated to a flowable state comprises a filter head defining a melt passage for the heated thermoplastic material, and a guide channel having entry and exit sections arranged on opposite sides of the melt passage. The entry and exit sections are configured and arranged to direct a continuous screen filter along a guide path extending transversely across the melt passage from an entry side to an exit side of the filter head. The screen filter is incrementally advanced along the guide path. An internal first cavity is provided in the filter head on an upstream side of the filter screen and at a juncture of the melt passage and the exit section of the guide channel. The first cavity is positioned to receive contaminants accumulated on the screen filter. A waste removal mechanism removes contaminants from the first cavity.

Abstract: A load cell in accordance with the present invention comprises an insert defining a hub having a central opening dimensioned to receive a shaft. The insert is removably fixed to the shaft, and a cylindrical sleeve is configured and dimensioned to surround the insert. The sleeve is machined with interior notches. The insert is suspended and rotatably fixed within the sleeve by flanges which are integral with and project from the insert's hub into the sleeve's interior notches. The flanges are configured to respond with deformation to forces applied to the shaft, and strain gauges bonded to the flanges exhibit changes in resistance according to the degree of flange deformation.

Abstract: An apparatus for slitting a web moving along a path comprises a mounting block adapted to be fixed at a location adjacent to the web path. A guard assembly includes a guard plate secured to rod members projecting from the mounting block. A blade guide is mounted on and shiftable along the rod members, and at least one blade is carried by the blade guide. An actuator serves to shift the blade guide along the rod members between an extended position at which the blade projects in a slitting position beyond the guard plate and into the web path, and a retracted position at which the blade is withdrawn from its slitting position and from the web path to a position where it is shielded from exposure by the guard plate.

Abstract: A joint is provided for articulately interconnecting the adjacent ends of rail assemblies in a tenter frame. The rail assemblies are arranged consecutively along a guide path, and have parallel guide channels for the advancing and returning legs of continuous chains carrying the clamps that grip the edges of the webs being transversely stretched. The joint includes flexible bands arranged to define intermediate channels connecting the guide channels of the rail assemblies. The flexible bands are resiliently deflected in response to articulation of the rail assemblies to thereby arcuately configure the outer medicate channels.

Abstract: An apparatus for continuously winding web material into a succession of rolled packages includes spaced side frames which define a transfer path leading from a first winding station to a second winding station. A plurality of rotatably driven winding drums extend between the side frames and support the cores and packages wound thereon during a winding operation which begins at the first winding station and continues during transfer of the cores to the second winding station. Tracks are fixed to the side frames which mount a transfer carriage movable on the tracks between the first and second winding stations. A first hold down mechanism and a first rider roll are carried by the carriage and a second hold down mechanism and second rider roll are located at the second winding station. The first hold down mechanism engages grooves in the ends of mandrels which are inserted into the cores to axially stabilize the mandrels.

Abstract: An improvement for casting machines is provided which assures a constant thickness and density of extruded material by varying the speed of nip forming rolls.

Abstract: An improvement for casting machines is provided which displays a correct nip measurement based on the relative position of cooperating rolls and the thermal expansion of the rolls.

Abstract: An air knife is illustrated having an adjustable orifice which includes a flat plate forming a baffle on one side while on the other side a flexible plate is secured along one edge to the circular plenum offering a free edge portion which may be drawn inwardly with respect to the flat plate to form an adjustable opposite side of the orifice.

Abstract: An apparatus is illustrated for packaging narrow fabric such as webbing, belting, ribbon and the like into rolls or blocks for shipment wherein, a manually operated means which is normally out of engagement during a packaging operation may be urged from the hub side of the reel to dislodge the package for removal for doffing from the reel, and a power operated means is provided for moving a gripping flange into and out of packaging relation to the package mounting flange and hub.
