Abstract: The invention relates to a hair styling device, and in particular to a hair straightener. The hair styling device (10; 210) has a first arm (12; 212) and a second arm (14; 214), the first and second arms being moveable relative to one another between a closed or operative condition and an open or inoperative condition. The first member (12; 212) has a first heating panel (16; 116; 216) and the second member (14; 214) has a second heating panel (18; 118; 218). The heating panels (16, 18; 116, 118; 216, 218) are corrugated to increase the length of the path the hair must take between the heating panels. The first and second heating panels are spaced apart in the operative condition so as not to press or clamp the hair therebetween.

Abstract: The invention relates to a hair styling device, and in particular a multifunctional hair styling device having components which can carry out a number of different (and distinct) styling operations. The invention provides a hair styling device having a body portion and a handle portion, the body portion having an air inlet and an air outlet, an impeller between the air inlet and the air outlet and an electric motor to rotate the impeller, the handle portion having a pair of heating panels. The handle portion is separable from the body portion and can be used alone as a hair straighter, or the device can be used as a hair dryer with the handle portion attached to the body portion. The body portion can optionally include a hair curling chamber adapted for hair curling.

Abstract: This invention relates to a hair styling device, a hair styling method, and a drive system suitable for use in the hair styling device. The invention relates in particular to a hair styling device (10; 210) for imparting a wave to a section of hair (36) without clamping the section of hair in the wave form. The device has a first forming member (24) and a second forming member (24) with a hair-receiving region (38) between the forming members. A driving member (20; 120) is movable relative to the first forming member and the second forming member to deform the section of hair in the hair-receiving region.

Abstract: A hair styling device is described, for waving hair by forming a length of hair into a wave form. A first forming member, a second forming member and a third forming member are located within a chamber of the device. There is a first hair-receiving region between the first and second forming members and a second hair-receiving region between the second and third forming members. A first driving member drives a portion of the length of hair into the first hair-receiving region and a second driving member drives another portion of the length of hair into the second hair-receiving region. The first and second driving members move independently and sequentially so as to reduce the tension applied to the length of hair.

Abstract: This invention relates to a hair styling device, and in particular a hair waving device. The device has a chamber for containing the length of hair, and a first forming member and a second forming member within the chamber, a first hair-receiving region between the first forming member and the second forming member. A first driving member can move relative to the first forming member between an inoperative position outside the first hair-receiving region and an operative position within the first hair-receiving region. The first driving member drives a portion of the length of hair into the first hair-receiving region to form a first wave in the length of hair. The device can comprise multiple forming members and multiple driving members to produce multiple waves.

Abstract: A polygonal lid and container base provide secure and reliable engagement therebetween, while also facilitating removal of the lid without disturbing contents and without applying undue stress to the lid. The lid includes at least one graspable member near or at a designated “release” vertex that facilitates disengagement of the lid from the container base at the release vertex. The lid further includes regions of enhanced engagement that enhance the attachment of the lid to the container base at least along the two sides of the lid that adjoin the release vertex, causing the overall attachment to be less dependent on attachment at the release vertex. As a result, the strength of attachment at the release vertex can be made weaker than at the other vertices, for easy release of the release vertex, without undue weakening of the overall attachment of the lid to the container base.

Abstract: A nuclear magnetic resonance method and apparatus are disclosed. A sample is provided where the nuclear spin Hamiltonian operator of the component molecules of the sample possess one or more symmetry operations. A quasi equilibrium nuclear spin ensemble state in a sample is created. The quasi equilibrium nuclear spin ensemble state includes at least two manifolds of spin states which transform differently under the symmetry operations of the Hamiltonian and the manifolds having different mean nuclear spin populations. The quasi equilibrium nuclear spin ensemble state is allowed to remain for a time of equal to or substantially greater than 3T1, where T1 is the spin lattice relaxation time. The symmetry operation of the Hamiltonian is broken. A sequence of magnetic fields is applied to generate a nuclear magnetic resonance signal from the sample. The nuclear magnetic resonance signal is detected.
