Abstract: A dunnage converter mechanism for producing relatively low density pad-like cushioning dunnage product from flexible sheet-like stock material in roll form. The converter includes means for pulling the sheet-like stock material from a supply roll thereof into the mechanism while causing inward rolling of the lateral edges of the sheet-like stock material, resulting in a pad-like cushioning product emitted from the machine, with the product having lateral relatively resilient pillow-like portions and a central connecting section holding the pillow-like portions together in generally side-by-side attached relation.

Abstract: A selectively pivotal hinge including first and second hinge elements pivotally connected together about a pivot point. The inner portion of the first hinge element is formed into a circular dial disk having a plurality of spaced transverse peripheral apertures adjacent its periphery and having a transverse central aperture at the hinge pivot point. A stem is slidably disposed in the central aperture. A biasing element in the form of a coiled spring contacts the first hinge element and the stem to bias the stem toward the disk. The second hinge element has an abutment which projects toward the hinge pivot point and is disposed below the disk. Two radial dial arms are rotatably secured to the stem at one longitudinal point thereon for circumferential rotation on the stem. The arms extend radially outwardly over the disk peripheral apertures.

Abstract: A device for facilitating the movement by a patient of an incapacitated limb comprising, a base adapted to be supported on the thigh of the patient's limb, a lever pivoted to the base, a lifter member attached to the lever and adapted for coupling to the patient's limb generally adjacent the distal end thereof, for connecting the limb to the lever, thereby enabling the patient to shift the incapacitated limb by acutuation of the lever, and wherein the lever and the lifter member include manually actuatable mechanism for selectively adjusting the lengths thereof, for accommodating the device to different sizes of patients. The lever also includes an adjustable projecting handle portion.

Abstract: A centrifugal filter separator system operable to separate from oil under pressure solid contaminants, by depositing them on the internal wall of a rotating drum, powered by reaction jet nozzles, while also separating water from oil and extracting it from the rotating drum through a water extraction circuit. A water-oil mixture from the water extraction circuit is passed through a pressurized gravity type separator, from which the separated oil is returned, on a continuous basis, back to the centrifugal filter separator system, while the quantity of the water retained in the gravity type separator is controlled by a water ejecting automatic control, responsive to the position of the water-oil miniscus, or to the position of the layer of water-oil emulsion separating water and oil within the separator.

Abstract: Resin is mixed with graphite particles to form a blendable, processable premold coating. When the premold coating is incorporated onto the surface of a premold coated molded plastic product produced by the premold process, said coating is rendered electrostatically conductive.

Abstract: An integral electrical switch adapter for mechanically and electrically connecting a battery to a switch module without wires or soldered connections. The adapter includes a generally planar base having a first pair of flexible upstanding spaced attachment arms at the sides of the base for detachably securing the adapter to an associated electrical switch speed control module. The base also has a second pair of flexible downwardly extending spaced electrically conducting attachment arms at the sides of the base for electrically and mechanically securing the adapter to leads on an associated battery in detachable relationship therewith. The base also has a pair of upstanding elongated electrical switch bayonnet-type prong connectors on the front of the base and electrically connected, respectively, to the second pair of attachment arms for detachable electrical connection to associated leads on the module, thereby mechanically and electrically connecting the battery to the module.

Abstract: A method of forming a resinous embossing plate adapted for use in an embossing and diecutting press for embossing a design onto paper greeting cards. The method comprises providing a line sketch of a design, making a photographic negative of the line sketch, and using the negative to apply the line sketch to both sides of a thin sheet of soft embossable material. Manual indenting of the design into the embossable sheet to provide a female matrix on one side of the embossable sheet. The embossed sheet is then reversed, so that the male portion of the matrix design faces upwardly, and disposed in a mold enclosure. Liquid plastic and fibrous reinforcing material is added to form a relatively low cost embossing plate. Plastic negative of the embossing plate is used in the press in conjunction with the embossing plate, for embossing the design onto the paper greeting card stock.

Abstract: A surgical appliance support is provided which is secured to the patient's chest or back and accommodates respiration tubes, oxygen-air mixing elements, catheter suctioning lung equipment, alarm devices, and the like. The support is comfortable, sanitary, and safe for use with long-term patients.

Abstract: A combined heat shield and steam distributor for a cooking oven, adapted to be located in the oven between a flame producing combustion unit in the oven and a movable food product conveyor, to aid in protecting food product on the conveyor from generally direct exposure to flame, with such shielding and distributor means also providing for distribution of steam into the cooking chamber for intermixing with the gaseous cooking medium of the oven.

Abstract: A mechanism for producing low density pad-like resilient cushioning dunnage product from sheet-like stock material, such as for instance paper, comprising a support for rotatably mounting a roll of sheet-like stock material in operative condition thereon, and projections on the support adapted for coupling with receptacle structure defining recesses on a separable mobile cart, for detachably coupling the cart to the mechanism, with the cart having mounts thereon for rotatably mounting a roll of sheet-like stock material and in position for feeding the stock material into the dunnage producing mechanism, when the latter and the cart are in coupled condition, to create the pad-like cushioning dunnage product.

Abstract: An oven and method for cooking food products. The oven comprises an elongated housing having an inlet for food products to be cooked in the oven and an outlet for emitting cooked food product from the oven, together with means for heating a gaseous cooking medium in the housing for cooking the food products therein, and a plurality of vertically tiered endless conveyors for passing the food product back and forth through the housing during the cooking process, whereby an oven taking less floor space for a predetermined flow path extent of cooking various food products, is provided.

Abstract: A control valve for variably controlling the mixing and dispensing of two fluids and which valve has a primary valve and a slave valve interconnected to the primary valve and responsive to one of the fluids to actuate the primary and slave valves to either a valve closed or valve open position whereat in the latter position the mixture and dispensing of both fluids is accomplished.
