Methods and systems are presented to protect clothing of a wearer using a first collar structure and draping structure that are separately adjustable and releasable. In some variants the draping structure may include magnetic or other positioning elements to accommodate wearers of various sizes. Likewise the collar structure may include magnetic or other positioning elements that are indirectly and effectively supported by the still-closed draping structure while undergoing a transition through a range of unstable positions thereof between stable open and closed positions thereof. This allows a stylist to uncover and re-cover the wearer's neck much more frequently and quickly, for example, during a hair dye or style treatment.

The invention relates to an electrode suitable for decreasing the chemical oxygen demand of waste-water comprising: a) a permanent component; and b) a sacrificial component arranged face-to-face and releasably attached to the permanent component and in electrical contact therewith, said permanent component consisting of a Substrate of a valve metal equipped with a catalytic coating containing noble metals or oxides thereof, said sacrificial component containing elemental iron. Further the invention relates to a method for abatement of the chemical oxygen demand in an aqueous waste containing oily compounds, glycols or waxes, optionally consisting of a foundry waste, by an electrolytic process involving anodic chlorine evolution in the presence of trivalent iron. Chlorine evolution may be carried out on the surface of an anode consisting of a catalytically activated-valve metal permanent component coupled to an iron-containing sacrificial component.

A hair sectioning device includes a headband having a plurality of complementary connectors and a shape, size and construction material that is suitable for being worn about the head of a user. The device also includes a plurality of dividers that create a stencil having a plurality of user-defined sections for receiving the user's hair. At least one of the dividers including an elongated elastomeric cord having a pair of connectors located along each end thereof. Another of the at least one of the dividers includes multiple elongated elastomeric cords that are pre-arranged to form distinct shapes. Each of the elastomeric cords also including a connector for engaging the complementary connectors positioned on the headband.

For a hairdressing cape, a round opening is formed at the center of an upper region of at least a front cloth and a back cloth, and a collar portion with an overlapping portion is formed which is sewn to a peripheral edge of the round opening by folding an edge portion. A clasp is mounted to an inner end portion at one side of the overlapping portion of the collar portion, and a ladder tape is mounted from near an end portion at the other side of the collar portion to an upper region of the back cloth. By making the clasp be caught and fastened in an arbitrary position of the ladder tape, the overlapping portion of the collar portion is fastened.

The present invention relates to a haircut cape device. The device preferably resembles the upper body and cape of a superhero and has a curved lip that encircles the body such that any hair cut from the user during a haircut is collected within the lip. The lip preferably ends above the lower arm of the user such that their hands are free to move during the haircut.
