Abstract: An ozone generating cell includes at least two substantially planar electrodes at a potential difference separated by a dielectric sheet, each producing a corona discharge to convert a proportion of any oxygen present to ozone. The electrodes, when considered in plan, are generally offset with regions of the electrodes overlapping or almost overlapping each other, and regions of both electrodes not overlapping each other. One or both planar electrode may feature extending planar portions of a substantially rectangular ‘U’ shape.

Abstract: The present invention encompasses methods for treating chronic fatigue syndrome and fibromyalgia by administering buprenorphine or a salt thereof. The compound may optionally be administered in a pharmaceutical composition. Preferred compositions for delivery of the buprenoiphine are sublingual lozenges and transdermal gel.

Abstract: A disposable teeth cleaning kit includes a finger mounted toothbrush having a substantially cylindrical elastic sheath with a closed end and an open end. The sheath can be provided with internal longitudinal torque ridges to prevent rolling of the sheath during use. Brush means is disposed on the sheath adjacent its closed end and the sheath is adapted to be furled into a compact configuration wherein the furled portion forms a substantially annular rim bounding an area spanned by the closed end portion of the sheath and the brush means. The brush means is sized and configured to be surrounded and protected by the rim during storage and can be sealed in a protective sterile pod if desired. A sealed brush pod for attachment to an elastic sheath to form a finger mounted toothbrush comprises a base pad from which a bed of brush material projects. The bed of brush material is smaller than the pad to define a peripheral lip of the pad.

Abstract: A disposable teeth cleaning kit includes a finger mounted toothbrush having a substantially cylindrical elastic sheath with a closed end and an open end. The sheath can be provided with internal longitudinal torque ridges to prevent rolling of the sheath during use. Brush means is disposed on the sheath adjacent its closed end and the sheath is adapted to be furled into a compact configuration wherein the furled portion forms a substantially annular rim bounding an area spanned by the closed end portion of the sheath and the brush means. The brush means is sized and configured to be surrounded and protected by the rim during storage and can be sealed in a protective sterile pod if desired. In use, the toothbrush is unfurled onto a user's finger whereupon the finger is manipulated in the user's mouth to clean the teeth. When the teeth are cleaned, the brush is unfurled from the user's finger and discarded in an appropriate refuse receptacle.

Abstract: This invention provides a steel alloy, for use for razor blades, the ranges of composition of which are given in the table below, the first column giving the maximum range for the alloy elements and impurities (the balance being iron), the second column giving a narrower preferred range, whilst the third column gives a particularly advantageous composition:______________________________________ Maximum Preferred Element Range Range Example ______________________________________ Ni% 15 to 25 17 to 22 20 Cr% 3 to 8 3.5 to 5 4 Ti% 2 to 5* 3 to 4.5 4 Al% 1 to 5* 2 to 4 3 C% less than 0.02 0.01 0.005 Mn% less than 0.2 0.1 0.05 Si% less than 0.2 0.1 0.05 N% less than 0.02 0.01 0.003 P, S% less than 0.02 0.01 0.

Abstract: A porous pen nib comprising a plastics sheath and a fibrous core, preferably of textile yarn, has a writing tip formed by the rim of the mouth of the sheath and a protruding core center which both wear smoothly and equally in writing use.

Abstract: The present invention provides a member having a cutting edge with a boron-containing coating thereon, the coating being up to 600 Angstroms thick. The member may be a razor blade.The invention also provides a method of manufacturing a member having a cutting edge which includes the step of coating the cutting edge with boron to a thickness up to 600 Angstroms.
