Abstract: A process of brazing a cover to an open body for a hollow vane assembly including forming an open body, the open body including an interior; forming at least one cover support structure in said open body proximate the interior; forming a cover, the cover being configured to couple with the open body to form at least one flow passage; and brazing the cover to the open body.

Abstract: The invention relates to a device for harnessing energy from a body of water, which device comprises a Darrieus rotor having at least two Darrieus rotor blades, and comprises at least two connecting arms which connect the Darrieus rotor blades with a central axis, wherein per Darrieus rotor blade a first, proximal section of a connecting arm is connected to the central axis and a point of the connecting arm situated at a distance of the proximal section is connected to a first point on the Darrieus rotor blade, wherein at least the connection between the point of a connecting arm situated at a distance of the first proximal section and the first point on a Darrieus blade is a hingable connection, for every Darrieus rotor blade, of at least one connecting arm the connection between the proximal section of the connecting arm and the central axis is a rigid connection.

Abstract: Spray compositions and particularly anhydrous aerosol compositions containing particulate antiperspirant actives exhibit a tendency for nozzle blockage, impeding discharge of the contents when a polyol humectant, such as glycerol, is blended into its base composition. The problem is overcome or at least ameliorated by preparation of a base composition, suitable for employment in conjunction with a propellant, that contains a low molecular weight (liquid) polyethylene glycol (PEG) as humectant, and particularly a PEG of molecular weight 150 to 500.

Abstract: A mild toilet bar composition contains C8-C18 mono and diacyl isethionates in a specified ratio in a first preferred embodiment of the invention and a specified ratio of calcium and magnesium diacyl isethionates in a second preferred embodiment of the invention. Both toilet bars provide substantial lather, mild cleansing, low mush and wear rate levels during use.

Abstract: Incorporation of a polyol humectant in an anhydrous composition containing an astringent aluminium and/or zirconium antiperspirant salt can result in grit formation and hence poor sensory properties unless the polyol is prior contacted with a perfume carrier. A simpler manufacturing process that enables the composition to retain its moisturising properties employs 20 to 90% of a carrier oil plus up to 10% of a liquid, low molecular weight polyethylene glycol as humectant, preferably having an average molecular weight of from 190 to 600, not prior complexed with the antiperspirant salt.

Abstract: A test method is described for comparing the relative affinity of products for a target substance using a substrate ordinarily and visibly sensitive to the products. The test method is useful in one embodiment for comparing the ability of harsh cleansers to remove fatty acids from the skin with mild cleansers that do not remove fatty acids to the same extent using a visually compelling substrate, such as a fresh cut flower.

Abstract: An aerosol cleansing composition that is self-supporting after dispensing is described whose volume does not noticeably shrink with time. The inventive composition can be used in place of toilet bars when it is inconvenient to use such bars and provides the user with substantial lather and optionally warming agents, skin conditioners and/or skin active agents. A method for cleansing the skin without rinsing with water is also disclosed where the inventive aerosol cleansing composition is applied to the skin and wiped off.

Abstract: Liquid lamellar cleansing compositions are described that contain synthetic surfactants, hydrophilic emollients and exfoliant particles where 80% or more of the particles have a major axis length of between 100 and 1000 microns. The combination of the mild surfactants, moisturizers, and exfoliants provide the user with simultaneous moisturization and exfoliation in a convenient liquid cleansing product.

Abstract: Toilet bar compositions are described that contain specific odor masking agent(s). The odor masking agent(s) reduce malodor without the need for elevated amounts of masking fragrances that individuals may not prefer and who use the composition for personal cleansing or who are exposed to the composition.

Abstract: A mild toilet bar composition is described that contains both C8-C18 diacyl and monoacyl isethionates in a specified ratio and a minor amount of soap if any. The toilet bar provides mild cleansing and low mush and wear rate levels during use.
