  • Patent number: 8973579
    Abstract: An apparatus for deploying oxygen masks that includes a pre-packaged modular system that does not require manual repacking of oxygen masks by aircraft technicians. The cartridge is for use with a manifold having a passageway in fluid communication with a source of breathable gas. The cartridge includes an end wall, a sidewall extending from the end wall and terminating at a distal end adjacent to an opening. A flexible member defines a chamber inside the cartridge. The chamber is in fluid communication with the passageway when the cartridge is coupled to the manifold. The flexible member has an outlet. A mask assembly is disposed inside the cartridge. The mask assembly has a hose coupled to the outlet of the flexible member. A cover is removably attached to the distal end of the at least one side wall.

  • Patent number: 4602732
    Abstract: The method of joining and sealing a wrought aluminum hot water generator with the cover and the die casting forming walls of a hot water channel wherein a weld bead is laid on top of and between the cover and the die casting. The weld bead is then compressed by a flat steel plate to squeeze out any small pockets of gas that could destroy the water tight integrity of the weld.

  • Patent number: 4546697
    Abstract: An electric drip coffeemaker hot water generator wherein a unique self-cleaning water channel construction is provided in an aluminum casting. A plurality of transverse lands and grooves are formed in the walls of the water channel so that mineral deposits that build up on the lands and grooves and other surfaces of the water channel will crack off or flake away in relatively small chips from differential thermal expansion and contraction. The small chips will be flushed through the channel and into the coffee grounds.

  • Patent number: 4190208
    Abstract: In a food processor with a power base and a lid-covered bowl, a feed chute through the lid empties onto a cutting disc rotated by a shaft extending into and terminating in the bowl. To this general combination an improvement in the disc structure is provided comprising a peripheral flange around the disc edge extending upwardly adjacent the bowl inner surface, with a single substantially rectangular locking bevel-edged opening through the disc and flange on one side only of the disc's center, the opening terminating short of and adjacent the disc center. A narrow slot is provided centrally of the opening to extend across the disc center and a depending hub on the disc at its center crosses the slot to receive the shaft. A removable beveled-edged cutter blade insert has a tab matching the slot and the insert is radially slidable into the opening and the slot to contact the hub.

  • Patent number: 4173310
    Abstract: A rotary cutter blade for use in an unfluted constant diameter bowl of a small series motor driven food processor with a rotatable hub is provided where the blade comprises a cutting surface formed in two distinct curvatures of substantially equal radii with a first inner surface including a long circular outwardly convex cutting edge having its center of curvature offset a given amount from the hub axis and terminating inwardly of the bowl inner surface and having a second outer surface of a short circular outwardly convex cutting edge with its center of curvature being a lesser amount offset from the hub axis and extending from tangency with the bowl inner surface to terminate in a substantially pointed intersection with the first cutting edge and the first and second cutting surfaces having lengths substantially in the ratio of 3 to 1 where the particularly formed blade permits use of a series motor without stalling or jamming by wedged pieces of food between the blade and bowl.

  • Patent number: 4153210
    Abstract: A food processing appliance has a base and removable bowl with a cutter mechanism therein which is supported on and driven from a power unit in the base at selected speeds. The invention provides an improvement of a removable reducing transmission disposed directly in and removably coupled to form and close the bottom wall in the bowl and having a portion extending into the bowl for supporting the cutting mechanism. The transmission is disposed entirely external to the base and is driven from the base whereby the selected removable bowl can only be connected to the base for food processing when the transmission is coupled directly to the bowl.

  • Patent number: 4128939
    Abstract: A cutter construction for a vegetable peeler that has a cylindrically electrically rotatable body with a longitudinal mounting shaft and a plurality of longitudinally extending slots coextensive with and equally spaced around the body and a cutter blade disposed lengthwise from the body outer end to the inner end in each slot. In this general arrangement an improved slot and blade configuration is provided wherein each blade is disposed in its own slot with its entire cutting edge angled or slanted in the direction of rotation and with a high point in an operable permissible range above the body periphery a maximum of 0.030 inches (0.75 mm) and a minimum of 0.008 inches (0.20 mm). A clearance recess is provided below and coextensive with each blade and extending substantially at right angles to the blades in the direction of rotation. It has a peripheral width from substantially 0 inches to 0.180 inches (4.5 mm).

  • Patent number: 4091551
    Abstract: The invention is directed to an extra capacity steam iron with a soleplate having steam ports and heating means and separate forward main, and rear surge, steam generators with conventional means for selective delivery of water to the generators and having a heat regulating thermostat. The improvement to this structure comprises a walled enclosure on the soleplate defining the surge generator in the rear half of the iron and tortuous passages lead from the enclosure to the soleplate ports. A boss is provided upstanding from the soleplate spacedly disposed in the enclosure and a coverplate defines steam distributing passages from the main generator and, with the enclosure and the passages, separate distributing passages from the surge generator. The upstanding boss is in the form of a pyramid with plural slanted striated surfaces sloping toward the soleplate, the striations being in the form of parallel grooves directed down the surfaces to spread and direct water into the enclosure.

  • Patent number: 4073056
    Abstract: A vegetable peeler with a handle supporting a cylindrical and electrically rotatable shafted cutter body connected to the handle with a plurality of spaced cutter blades extending longitudinally from the outer to the inner end of the body and a fixed splatter shield partially surrounding and spaced from the body and supported directly on the handle. In this general arrangement there is provided an improved cutter and shield release assembly of a cylindrical tapered support surface on the handle and a matching tapered support surface on the shield for telescopically locking the parts together. A cam and slot connection between the surfaces of different sized pins entering cooperating angled slots cams the tapered surfaces together and locks them. The body has a flared inner end and an abutment is provided on the shield adjacent the flared end so rotation of the shield breaks the tapered connection while simultaneously abutting the body to release the cutter without handling it.

  • Patent number: 3949499
    Abstract: An iron with fluid handling means and a removable tank assembly that has a tank support and a conduit that extends from the fluid handling means into the tank when it is disposed on the support. Means are provided to fill the tank when removed and a pliable plug means is disposed in the tank and split to accept the conduit therethrough in a sealing relation permitting fluid flow from the tank to the handling means so that the conduit pierces the pliable plug in a tight seal when the tank is placed in position and the plug seals itself when the conduit and tank are separated for filling.

  • Patent number: 3942706
    Abstract: A steam iron soleplate, generator, and distributor subassembly of a thin soleplate with a coverplate spaced from and supported on the soleplate by spaced peripheral rib means to define a steam distributing passage therebetween. The coverplate is integrally attached to the soleplate by a continuous weld between the ribs and soleplate and steam generating means are provided in the upper surface of the coverplate separate and spaced from the soleplate and ducted below to the steam passage means. A heat generating element forms an integral part of the coverplate for heat transfer to the soleplate through the ribs primarily by conduction. Both the method of assembly and the subassembly itself are disclosed.
