Abstract: A slurry product is packaged into a plastic bag using a modified form-fill-seal apparatus. A method for making a plastic bag filled with a desired weight of a slurry material on a form/fill/seal machine, includes drawing a plastic film over a mandrel of a form/fill/seal machine and wrapping the film around a forming tube. A tube of plastic film is formed by bonding the edges of the film together and the bottom of the tube is sealed. An initial weight is obtained by weighing the mandrel and the tube of plastic film then a slurry composition is deposited inside the closed tube. The present weight of the mandrel, tube of plastic film and contents of the tube are monitored as the slurry is deposited, and the present weight and the initial weight are compared until a desired weight is reached. After the desired weight is reached, the filled bag is sealed and separated from the tube of plastic film.

Abstract: Described is a hook for hanging articles, such as garments, which is capable of holding the weight of a typical garment while permitting the release of heavier objects. The hook has a base, an arm pivotally mounted to the base, a releasable connecting means for releasably connecting the arm to the base to maintain the arm in a load bearing position, the releasable connecting means (e.g. magnetic means) releasable to permit the arm to move towards a load releasing position when a load having a weight in excess of a predetermined weight is applied to the arm; and effort imparting means (e.g. a weight) mounted to the arm for returning the arm to the load bearing position after the load has been released. Such hooks are particularly useful in schools to reduce the possibility of children being hung from hooks.

Abstract: A bolster having a plurality of flat surfaces on the opposite side thereof arranged to provide a surface on which the saddles of an air brake assembly are fastened.

Abstract: A railway vehicle truck friction shoe pocket including a sloped wedge wall and longitudinally spaced depending walls of which at least one of the inner planar faces is provided with one or more relieved sections.

Abstract: A friction shoe particularly adapted for providing improved regulation of movement between a bolster and a side frame of a railroad car truck includes a central body portion and triangular-shaped wings formed on each side thereof. Pairs of these friction shoes are disposed in pockets formed at the ends of the bolster which in turn are resiliently carried in a window formed in each side frame. Each friction shoe wing has a downwardly and outwardly sloped wear surface to form a convex-like seating area. In turn, each bolster pocket has complementarily formed friction surfaces providing a concave-like receiving area. During operation of the truck, the shoe seating area interacts with the bolster pocket receiving area to produce a wedging action. This wedging action in turn insures improved frictional regulation of side frame-bolster movements and maintains such in an aligned relationship.
