Abstract: A main frame pivotally supports the forward ends of a laterally spaced apart pair of parallelogram linkage systems. Each linkage system comprises an upper link and a two section lower link, rear ends of which are pivotally interconnected to a rear shackle, the lower end of which has a ground engageable roller. A load platform is pivotally connected along its forward edge to the rear ends of the upper links. The rear sections of the lower links are rigidly interconnected by a lift frame that is fitted at its opposite ends with upstanding crank members. A hydraulic piston cylinder mechanism is mounted adjacent each linkage system with its butt end pivotally connected to the main frame and the piston rod of each cylinder is pivotally connected to one of the upstanding crank members. The forward and rear sections of each lower link are pivotally interconnected by a knuckle pin and each lower link includes stops to bidirectionally limit relative angular displacement of the two sections.

Abstract: A flow splitting junction of a pipeline network for a two-phase fluid is internally fitted with a static mixer, a multi-duct stratifier and a divider wall. The turbulent fluid exhausted from the mixer is separated by the stratifier into two separated sets of alternating laminarly flowing strata to be discharged to opposite sides of the divider wall as two separate fluid streams of the same gas-liquid ratio which are conducted into separate downstream branches of the junction.

Abstract: A self-closing hinge comprising a pair of hinge leaves pivotally interconnected by an offset hinge pin. A spring tang is formed integrally with one of the hinge members and has a distal end that has a head projecting substantially radially with respect to a sleeve of the other hinge leaf within which the hinge pin is mounted. The external surface of the sleeve serves as a cam surface against which a follower element carried on the head of the spring tang is biased. The line of force exerted by the head of the tang through the follower is distally offset relative to the axis of the hinge pin. During closing of the hinge the follower is brought into registration with a pocket formed in the sleeve effecting a rocking movement of the follower about one edge of the pocket to generate a self-closing moment.

Abstract: A forward platform section is hingedly connected at its forward edge to lower ends of a pair of runner assemblies that are vertically movably mounted in guides of a supporting framework. A closed rear edge of the forward platform section is hingedly interconnected to a closed forward edge of a rear platform section, the hinge connection being adapted for folding an underside of the rear platform section into superposition over an underside of the forward platform section. The curb side runner assembly incorporates a power cylinder for rotating the forward platform section between vertical and horizontal positions. A known linkage effects rotation of the rear platform section between vertical and horizontal positions as a function of corresponding rotation of the forward platform section.

Abstract: A thin and narrow sheet, having an inlet edge and an outlet edge, is formed on one surface, e.g., the top, with a continuous land that is parallel to the inlet edge. The inlet side of the land is coplanar with the inlet edge of the sheet or, alternatively, disposed slightly inwardly relative thereto. Inwardly behind the land the same surface of the sheet is formed with a plurality of channels defined between adjacent pairs of finger lands each of which extends between the outlet edge of the sheet and the inside of the continuous land. On its opposite side the sheet is formed with a like plurality of transverse lands that form fluid passages extending across the full width of the sheet from the inlet to the outlet edges thereof. The bottom surface lands register with the finger lands of the top surface of the sheet. A congruent stack of the sheets is compressively loaded through the lands to define a rigid filter column.

Abstract: The load platform of a lift is carried by a runner mounted for vertical reciprocation along a hollow guide column. Within the column the runner and its load are suspended from a short length of a leaf chain that, in turn, is suspended from a powered vertically reciprocable wire rope. The leaf chain extends between a pair of cam pawls pivotally mounted on a brake body carried by the runner, with the pivot axis of the pawls oriented parallel to the pivot axes of the links of the chain. The pawls are biased in a direction to move out of a retracted position into an extended position wherein they engage one side of the column to jam the brake body against an opposite side of the column. The pawls have a contact pin confronting one side of the chain such that when the chain is under tension it bears on the contact pin and so maintains the pawls in retracted position.

Abstract: A refuse compactor body has a tank section of an irregular polygonal right section that is uniform from end to end. The tank wall is made of rectangular pieces of thin very high tensile strength sheet metal and externally reinforced at spaced intervals longitudinally of the tank by polygonal peripherally continuous girth reinforcements, made up of straight short sections of metal tubes, to make a semi-monocoque structure. A floor portion of the tank is recessed between the longitudinal body support beams, which are the sole body support, to provide a relatively low center of gravity when mounted on a truck chassis. A hopper section of the body has a packer that obturates about two-thirds of the opening to the tank and is fitted at its upper edge with a follower that pivots to a shallower slope to keep refuse from falling behind the packer blade during a compaction stroke of the packer.

Abstract: A disposable ashtray for use on an open pop top beverage can. The tray is formed out of a flat blank of an aluminized paper sheet that has been scored to define a floor and erectable side walls for the tray. The floor is formed with (1) a passage to matingly receive the actuator tab of the pop top can and (2) a perforated score line defining a key tab portion that is displaced out of the plane of the floor to penetrate through the drink opening of the can.

Abstract: A cylindrical insert for a pre-existing pressure vessel has an integral accumulator chamber defining a head for the vessel. Inner end surfaces of the accumulator chamber, along with the walls of the pressure vessel, define a filter element chamber, the inner end of the accumulator chamber also supporting an array of permanent filter elements. The accumulator chamber is of annular form, around a central pipe which serves, alternately, as the outlet for filtered fluid passing from the filter chamber or as the inlet for filtered clean fluid to be forcefully pulsed back through the filter elements by the release of compressed air from the accumulator to flush them of an accumulation of filtered waste material. The insert system includes piping associated with the accumulator chamber for charging the chamber with highly compressed air and for selectively releasing the charge for backflushing, and control valves for placing the insert system in filtering and backflushing modes.

Abstract: A mandrel has its face formed to define a negative impression of reinforcing elements to be formed into the walls of a Bliss box. The reinforcing elements may comprise tubular corner posts and/or intermediate hollow ribs or posts. The mandrel is mounted in a machine frame for reciprocation along its axis so that upon full extension of the mandrel it is disposed within a die cavity in which the Bliss body panel is formed around a pair of upstanding end panels. When fully retracted, the mandrel is positioned beneath and adjacent to a pair of magazines for holding supplies of flat end panel blanks, positioned on opposite sides of a superstructure frame of the mandrel. The superstructure is fitted with spaced pairs of feed pawls, a first set of which strips the flat end panels out of the supply magazines to deliver them to an arrested position, corresponding to the retracted position of the mandrel, as a result of extension of the mandrel. Concurrently, the flaps of each end panel are partially shoed inwardly.

Abstract: A flow restrictor to minimize noise and cavitation, or other adverse effects, in regulating the flow of a high pressure fluid. The restrictor defines a myriad of tortuous, dissimilar, intertwined, and commingled energy dissipating chambered flow paths edgewise through a stack of sheets of perforated stock material. Adjacent sheets have their perforations out of registration with one another, the inlet and outlet to the restrictor being edgewise through the stack through open-sided ones of the perforations of the several sheets of stock.

Abstract: A fluid flow restrictor for spanning a passage of a body to minimize noise and cavitation in a high pressure fluid flowing through the passage and undergoing a substantial pressure drop in passing through the restrictor. The device comprises at least one tier of fixed perforated tubelets defining a myriad of tortuous flow paths with restricted orifices and expansion areas to dissipate energy in the fluid. The fluid flow through or between individual tubelets may be further subdivided into restriction orifices and expansion areas by additional fixedly held solid elements, e.g., BB shot tightly packed within the tubelets. The preferred inventive embodiment described is a sound suppressing, high pressure reducing poppet valve having several tiers, isolated from one another, of annular clamped arrays of parallel perforated tubelets.

Abstract: A sound suppressing fluid handling device wherein a relatively high pressure fluid is conducted through a substantial pressure drop, relatively noiselessly, by passage of the fluid through a myriad of tortuous energy dissipating passages formed between adjacent turns of and opening through the ends of a sound suppressing reel comprising a relatively thin flexible spirally wound band. The preferred inventive embodiment described is a valve comprising a stack of annular discs seating coaxially against the inlet end of the sound suppressing reel and containing passages, formed partly between adjacent discs, for conducting the incoming high pressure fluid from the central opening in the disc stack to the inlet ends of the reel passages.

Abstract: A machine for forming a container with full width 3-ply laminar end walls from a preformed cardboard container body blank having side and outer end wall ply forming panels along the sides and ends of a bottom forming panel and inner end wall ply forming panels extending endwise from the ends of the side wall panels. The machine erects and seals the body blank with a mandrel and forming die to form a finished container by applying glue to selected end wall panel surfaces, folding the inner end wall panels upwardly relative to the side wall panels, and then folding the side and outer end wall panels in succession to upright positions relative to the bottom panel to upstanding side by side positions inwardly of the outer end panel with the confronting end panel surfaces in mutual adhesive bonding contact.

Abstract: A load lifting and lowering platform comprises a pair of hingedly interconnected platform sections that are foldable between a horizontally extending, load bearing position and a vertically extending collapsed position. A forward one of the platform sections is hingedly connected at its forward edge to lower ends of a pair of runner assemblies that are vertically movably mounted in a supporting framework. A pair of chains are interconnected between upper ends of the pair of runner assemblies and outer ends of the outer one of the platform sections. Cooperating cam elements, interposed between the forward edge of the forward platform section and the supporting framework, translate vertical movement of the runner assemblies into angular movement of the platform sections, in cooperation with the chains, for folding and unfolding of the platform sections.
