Abstract: A gas burner for household may include a zone for mixing combustible gas with air to form an air-gas mixture, an inner chamber with an inner table, and including sides with crenellated walls. A vertex may be formed on each end of the sides, which may be formed by intersecting curved surfaces. A port zone may be on an upper face of the crenellated walls. The port zone includes main ports, which may be centric relative to the vertexes. The symmetry axes of the main ports may be aligned towards the vertex closest to a corresponding port. The ports may be equidistant relative to one another. A lid may close the inner chamber and pass the mixture through the ports. The curved surfaces may have different geometries. The lid may include a cavity, where another burner may be placed.

Abstract: A balance ring for washing machine devices as may be used in vertical and horizontal axis washing machines is provided. One structural arrangement of the ring comprises alternatively disposed positive and negative curved blades, as well as curved and straight blades, that in combination with the different heights of the blades, reduce the time and the amplitude of the vibrations of the transition state, thus enabling the washing basket to spin at higher velocities, and reducing the centrifugal cycle while increasing the centrifugal force applied to the objects being washed. Such an structural arrangement provides a superior drying of the clothes and further results in energy savings.

Abstract: A system to light a cavity 19 in an appliance. A source or light emitter 27 is mounted on a circuit board 32, so that the light emanating from said source or light emitter 27, is concentrated into a light beam using an optical collimator system 28 or in some cases a Fresnel arrangement; wherein the foregoing elements may be found outside a door 14, which allow access into the cavity; thus the light beam exiting the optical collimator 27 or Fresnel arrangement travels a distance though air between the optical collimator system 27 or Fresnel arrangement and the upper face of the light guide 29 which is placed on the door 14, the light guide 29 transports the luminous flux towards a notch which diverts said luminous flux directing into the cavity's 19 interior.

Abstract: A cabinet drawer support beam is provided, and may include on an upper part of such beam, a rail or longitudinal sliding mechanism. An alignment mechanism may be fastened to the rail or longitudinal mechanism. The alignment mechanism may include a pinion that runs in the rack of the lower part of the support beam, and the support beam may be fastened to the cabinet wall by way of barrels and/or fasteners. At least two beams per cabinet may be included.

Abstract: An auto-alignable knob for a home appliance includes an offspring box self-connectable with a valve shaft. A mobile box has at least one lateral face including a pin. The mobile box is coupled to the offspring box to allow a free movement relative to one another along a first axis. A fixed box includes an indentation and a groove. The mobile box is insertable to the fixed box by insertion of the pin of the lateral face through the groove. The pin of the mobile box provides a respective degree of freedom to the mobile box relative to the indentation of the fixed box along at least a second axis normal to the first axis.

Abstract: A link suspension coupled to a system is described which vibrates, which comprises at least four links supporting the system which vibrates by means of one Cardan joint and one foot, one articulation between the Cardan joint and the link, one articulation between each link, one articulation between the foot and a link; each articulation houses a spring. Further a cylinder and piston suspension is described coupled to a system which vibrates, which comprises a cylinder, a piston housed within the cylinder, an articulation fastened to an end of the cylinder and to a Cardan joint, an articulation fastened to another end of the piston and to a foot; a spring fastened to the cylinder and the piston, wherein the cylinder suspension is at an angle varying between 35° and 50° from the axis of symmetry of the system which vibrates.

Abstract: A panel for a household appliance which comprises a member which includes an inner surface, an outer surface, at least one inlay on at least one of the two surfaces where said at least one inlay has a polygonal form.

Abstract: The invention relates to an environmentally-friendly disposable absorbent article. At least half of the constituent materials used in the disposable absorbent article contain biodegradable compounds and/or compounds of natural origin.

Abstract: The present invention relates to a disposable absorbent article such as a sanitary napkin or a panty-liner, basically comprising an upper layer, a lower layer and an absorbent core of a design suitable to be used with tanga-type underwear, disposed between both layers; the core has a front section and a back section and wings or lateral projections preferably extending along the entire length of the absorbent core.
