Abstract: An apparatus for assisting the manual loading and unloading of bottles into and out of cases comprising a guide plate, a bottle holder, a bottle holder actuating mechanism, and a handle. The bottle holder comprises a pair of flaps pivotally connected to the guide plate, the flaps being adjacent and parallel to one another, and the flaps being movable between a closed and an open position. The flaps have a bottle retaining structure for retaining the bottles in the bottle holder. Each flap of the pair of flaps of the bottle holder has a pivot axis about which the flaps may pivot. The pivot axis is located below a plane defined by the tops of the bottles when the bottles are retained by the bottle retaining structure. The flaps are selectively moved between the open and the closed position by the bottle holder actuating mechanism, capturing the bottles within the bottle retaining structure.

Abstract: A method of making a double wall tank from a single wall inner tank. A mixture of an internal lubricating agent and a curable synthetic resin is formed and applied over an exterior portion of the tank which when cured forms a rigid outer sheath that is fluid tight and resists bonding to the inner tank.

At least two arcuate walls, having an axis generally coaxial with the axis of the shaft, are located generally concentric to and spaced apart from the shaft. The walls are configured to define at least two segments whereby entrance and exit to the air lock may be obtained. Each wall is connected to the bearing support apparatus and to the base with at least one of the walls having at least one aperture therethrough. A panel assembly comprises a plurality of panels with the inner edge of each panel connected to the shaft, such that each panel extends generally radially outwardly therefrom.

Abstract: An improved form, fill, seal and separate packaging machine for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web including means to attach a pair of mated, resealable closure strips to the base web. The machine is intermittent in its operation, with movement of the web through the machine controlled so that the various steps of applying the closure strips, forming, filling, sealing and separating the reclosable containers are performed during periodic stops of the machine. The machine is further characterized by its use of two pairs of web belts to move the web through the machine. A first pair of web belts initially receive the folded web stock and partially form and completely fill the containers. The second pair of web belts overlap with the downstream end of the first pair of belts, but are disposed lower than the first belts.

Abstract: A rechargeable filter assembly for removal of contaminants from liquids of all types, particularly dry cleaning solvents comprising three nested and spaced apart concentric perforated metal cylinders defining an inner cavity and an outer cavity held in spatial relationship by a base plate and removable lid. With the lid and outer perforated cylinder (exterior shell) removed, a removable and disposable filter unit may be placed within the outer cavity and similar, or different, filter medium may be placed within the inner cavity. The gaskets of the filter unit in conjunction with the lid, the base, the conduit, exterior shell and the inner perforated cylinder provide seals which prevent liquids from bypassing the filter unit.

Abstract: A protective cushion for a child's auto seat comprising a cover, padding encased by the cover and structure for removably attaching the cushion to the exterior of a child's auto seat, whereby persons or things seated or placed next to a child's auto seat, whether occupied or not, will be protected from injury or discomfort from the hard, angular or rough surfaces of the exterior of the auto seat.

Abstract: A plant display container with seeds and growth medium whereby growth of a plant may be monitored and measured. The elongated, transparent container encloses a growth medium, seeds and a measuring device. The measuring device is slidably inserted into the container above the seeds and the growth medium. As the plants grow from the seeds, they push the measuring device upward, physically measuring and visually demonstrating the amount of plant growth having occurred.

Abstract: A portable traffic control system for control of traffic at temporary locations includes a trailer having a base supported by an axle and wheels, two signal supports connected to the base and an actuating mechanism for selectively urging the signal supports from a transporting position to an operating position and back. A transverse arm connected to one signal support is extendable laterally and outwardly from the trailer. A signal head is attached to the transverse arm and a second signal head is attached to the upper end of the second signal support.

Abstract: A pine needle cutting apparatus for removal of pine needles trapped in screening, comprising a tool head having a removably attached cutting blade, brush, and handle connector to which a handle may be removably fastened. The cutting blade has opposing ends, a front portion, a rear portion, two arcuate portions, and a circumferential edge that defines the perimeter of the blade. The acruate portions of the front portion of the blade are adjacent each end. The circumferential edge along the front portion of the cutting blade between the arcuate portions has a cutting edge formed thereon and the remaining portions of the circumferential edge are dull. The circumferential edge along the front portion of the cutting blade is curved at a predetermined radius. The circumferential edge of each arcuate portion has a predetermined radius which is different from the predetermined radius of the front portion.

Abstract: A disposable nurser comprising a flexible bottle that is removably inserted within a bottle holder so that the open end of the flexible bottle is folded over the top edge and down the exterior sides of the bottle holder. A countercap comprising a sleeve is slidably mounted around the bottle holder and is slid upward from the bottom of the bottle holder, over the open ends of the flexible bottle, and upward until it engages a stop means that prevents the countercap from moving further. A nipple holding cap having a nipple inserted therein is removably attached to the countercap so that the nipple is sealingly connected in fluid flow relationship with the flexible bottle.

Abstract: A procedure is described for providing an angled pin seam on a papermakers felt in which a base fabric is woven with a selectively joinable pin seam to form a continuous loop of the base fabric, skewing that base fabric and its seam by displacing one of the lateral edges of the fabric longitudinally of the machine direction relative to the opposed lateral edge while maintaining the machine direction yarns extending substantially in the machine direction, thus skewing the seam relative to the machine direction and to the cross machine direction, and in which batt material is needled into the base fabric while the base fabric is maintained in the skewed condition, whereby the needled batt maintains the fabric in its skewed condition.

Abstract: A retaining wall anchor system of the type primarily used to tie retaining walls to dead men.

This apparatus includes a septum mounted within a waveguide, with that septum including a plurality of discrete interlinked elements mounted to a shaft supported longitudinally of the axis of the waveguide and includes apparatus for rotating adjacent elements angularly about the shaft along with structure for restricting the relative angular rotation of adjacent such elements about the shaft so that the maximum rotation of each element relative to an adjacent element is limited to a predetermined angle for that element.

Abstract: A lathe and a method of using the lathe are disclosed for forming an aspheric surface on a workpiece, in which the workpiece is mounted to a holder that is rotatably carried by the spindle, headstock and bed of a lathe, with that spindle and workpiece being rotated about the axis of the spindle with the workpiece being engaged by a forming tool which forming tool is moved through an arcuate path about an axis that is generally transverse to the spindle axis. The method and apparatus provide further for determining the time-varying angular position of the forming tool along the arcuate path, for determining the time-varying angular position of a point on the workpiece about the spindle axis and for reciprocating the workpiece holder and the workpiece held thereby relative to the lathe headstock and to the forming tool in synchronization with the movement of the forming tool and with the rotation of the workpiece about the spindle axis to form the desired contoured surface.
