One of the members includes a plurality of uniquely shaped slots and the other member a plurality of support rods, each accommodatable in a slot. To attach the unit, it is raisable by a single operator until the support rods are in the slots. Thereafter, the unit is rotatable and released, resulting in the rods being locked securely within particularly shaped portions of the slots.

The fourth side of each cavity is defined by a surface formed by the interlocking juncture between the two cavity plates. Plastic packages molded in the cavities thus are formed without a seam or parting line along the sides formed on the integral molding surfaces, the seam or parting line being formed only on the surface defined by the juncture of the two cavity plates.

Abstract: A valve and particularly a safety valve for use in controlling flow from a well in which an external motor is utilized to shift the actuator of a valve such as a ball valve. The reciprocating rod of the motor is protected by resilient means between the crosshead attached to the motor and the reciprocating actuator. The actuator is latched when the valve is in the open position so that it cannot be moved to closed position except by movement of the reciprocating motor. The valve and seat assembly are designed to be replaced as a unit and can be fabricated as a subassembly with the valve in exact open alignment when the reciprocating actuator is in full valve open position as determined by a stop against which the valve member bottoms.

The sealing member includes an anchoring portion held between opposed sidewalls of the support groove, and a convoluted portion extending radially inwardly of the anchoring portion, with a sealing portion carried thereby, and designed to extend beyond the groove, for engagement with the sealing surface. The groove sidewalls are of slightly greater axial width than the sealing member to permit limited elastic axial deflection.

Abstract: A valve of special usefulness in handling solids-containing or solids-producing fluids comprises a floating valve seat comprised of inner and outer rings, the outer ring being fixed within the valve body and the inner ring being urged directly from the outer ring by one or more springs against a gate element controlling the flow of fluids through the valve. The springs are housed within chambers provided by aligned cavities in the inner and outer rings while similarly aligned notches house a bellows or accordian shaped flexible metal seal. The flexible metal seal is in contact with the fluid but prevents entry of fluid between the rings to the spring; thus, the action of the inner and outer rings is not impeded by solids depositing from the fluid.

The screw is aligned with the second work plate and is actuated to positively force the work plates into alignment for welding. The tool is then removed by bending with respect to the bracket weld to break the weld.

Abstract: Device for the conveying of sheets from each of a plurality of sheet piles via a partially common conveyor track. This track extends in vertical direction along superposed stock holders. Adjacent to the sheet delivery side a driven roller is stationarily arranged above each pile. Each of these rollers can function both as suction roller for separating sheets from a pile and as friction roller for conveying sheets in the common track. For separating sheets from a pile, each pile can be brought by pneumatic means into short contact with a driven roller then functioning as a suction roller. For conveying sheets in the common track, each roller cooperates with a pressure roller. After a sheet in the common track has been gripped between a driven roller and a pressure roller, the sucting action of that driven roller is interrupted.

Abstract: An item dispensing system is disclosed wherein in a preferred sheet dispensing embodiment, primary and secondary sets of vacuum cups are mounted to one end of a pick arm which is rotated between a stack of sheets and a dispensing path. Initially, a two-way valve is controlled to pass a vacuum from a vacuum source only to one of the primary and secondary sets of vacuum cups. The selected set of suction cups then attempts to vacuum lift and pass a sheet to and along the dispensing path. The failure of a sensor to sense that sheet in the dispensing path within a preselected period of time indicates that the selected set of vacuum cups may have been unsuccessful in vacuum lifting that sheet from the stack due to a poor vacuum seal between the selected set of vacuum cups and that sheet. Such a failure causes a processor to generate a signal to cause the two way valve to apply the vacuum from the vacuum source only to the other one of the primary and secondary sets of vacuum cups.

Alternatively, the hollow core of the sheathing material may contain wooden or metal dowels to withstand high impact forces and provide more stiff resiliency. The dowel may be made in two parts, spaced from each other to prevent the full effect of the impact forces being felt by one holding the handle.

Abstract: An improved machine tool has a chuck assembly which is actuated by a piston and cylinder type motor assembly. When a workpiece is to be gripped by the chuck assembly, high pressure fluid is directed to one chamber of the piston and cylinder motor and is exhausted from the opposite chamber. When the chuck assembly has gripped a workpiece, relative movement between the piston and cylinder is interrupted and fluid is no longer discharged from the motor. A pressure responsive switch assembly detects the reduction in the rate of the flow of fluid from the motor to provide a signal to indicate that a workpiece has been firmly gripped by the chuck assembly. After an initial machining operation in which relatively high forces are applied to the workpiece, such as during a rough cutting operation, the chucking forces applied to the workpiece are reduced prior to initiation of a finish cutting operation.

Abstract: An improved chuck collet in which the elements of the collet, namely the jaw segments, the mounting base, and the interconnecting flexible members, are separate elements thus permitting a selection of materials for the elements to give optimum operating characteristics to the assembly at economical costs.

With the aid of the invention, sledge runners which have frozen fast to snow or ice can be easily freed by first backing up so that the load rolls into its rear position, whereafter the sledge is started, whereby with the aid of the load's mass the runners are jerked free from frozen-on snow and ice.

Abstract: A shopping cart is disclosed with a point-of-purchase advertising display which includes an octagonal, transparent display tube, rotatably mounted adjacent the cart's handle. The display tube is mounted on a shaft which is journaled on brackets on the cart's frame, thus isolating the tube from stresses arising from abuse of the cart. Advertising strips are mounted within the display tube for viewing as the tube is rotated by the cart's user. These strips may be replaced through use of a temporary support, as trunnions supporting the shaft are shifted outwardly to permit removal of the end cap of the display assembly. In another embodiment, a portion of the end cap is separately removable to permit replacement of the advertising strips. In a third embodiment, the shaft is omitted and the end caps are journaled on trunnions projecting from brackets on the frame of the cart. Also described is a method for assuring free rotation of the advertising display, when it is mounted on the frame of a cart.

The body has an integral rear fender where the rear wheel penetrates the rear triangle, and assymetrical rear forks in place of conventional rear frame stays. All control cables, and a cargo compartment, are contained within the frame.

Abstract: The present invention is comprised of extensible piston cylinders which extend between first points located on a trailer and second points located on a gooseneck which interconnects the trailer to a tractor. The gooseneck and the trailer are rotatably coupled to one another at a common pivot point and the common pivot point, the first points and second points are arranged relative to one another such that as the piston cylinder is extended or retracted the gooseneck and trailer are respectively raised or lowered relative to the ground. The gooseneck is arranged so that it substantially encloses the piston cylinders throughout their entire range of travel thereby protecting them from damage. In addition a locking apparatus permits locking the piston cylinders to both the first and second points to present rotation of the gooseneck relative to the trailer. Thus the gooseneck and trailer can be removed from the tractor as a single unit.
