A razor blade including a substrate with a coating joined to the substrate defining a coated blade. The coated blade including a cutting edge being defined by a blade tip having a tip radius of from 50 to 350 angstroms. The coated blade having a pair of first facets extending from the blade tip and a pair of second facets extending from the respective first facets, a facet angle from 90&#xb0; to 135&#xb0;, a facet width from 0.38 micrometers to 0.65 micrometers a wedge angle from 5&#xb0; to 30&#xb0;, and a thickness of between 0.8 and 1.5 micrometers measured at a distance of 1 micrometer from the blade tip.

Razor blades having a wide facet angle

A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has a thickness of greater than about 2.30 micrometers measured at a distance of four micrometers from the blade tip, a thickness of greater than about 4.26 micrometers measured at a distance of eight micrometers from the blade tip, and greater than about 7.93 micrometers measured at a distance of sixteen micrometers from the blade tip. A hard coating joined to the substrate has a thickness of 700 Angstroms to about 3500 Angstroms. An outer layer joined to a coated substrate is discontinuous. The outer layer may be produced from a dispersion comprising about 0.03 g/L or less of telomer or from about 0.5 % solids or less of telomer by weight of composition. The novel razor blade cuts at less than 100 % cutting efficiency using a single fiber cutting efficiency measure.

Razor blades

A razor blade having a substrate with a cutting edge being defined by a sharpened tip is provided where the substrate is comprised of a molybdenum (Mo) content of about 1.6% to about 5% by weight of composition and thicknesses of 1.60-1.75 &#x3bc;m and 9.25-10.00 &#x3bc;m measured at a distance of 4 and 40 &#x3bc;m from the blade tip, respectively. This thickness ratio is between 0.165-0.185. The substrate thickness is about 2.70-3.00 &#x3bc;m at 8 &#x3bc;m from the blade tip, about 4.44-5.00 &#x3bc;m at 16 &#x3bc;m from the blade tip with a thickness ratio measured at 4 &#x3bc;m and 8 &#x3bc;m between 0.56-0.62, and a thickness ratio measured at 4 &#x3bc;m and 16 &#x3bc;m between 0.32-0.40. The edge shape may be defined by equation w=adwith 'a' between 0.50-0.62 and 'n' between 0.76-0.80. A semi-included angle less than 7&#xb0; is measured at a distance of 40 &#x3bc;m or greater from the blade tip. This substrate will have substantially no cracks.

Razor blade

A novel razor cartridge includes at least one non-cutting element disposed anywhere within a blade array between a guard and a cap and/or in a blade position of a frame providing skin/hair management. This non-cutting element allows the fine-tuning of parameters such as blade-skin contact, hair orientation, blade spans and rinse-through gaps in manners that improve shaving comfort, closeness, efficiency, and/or rinse-ability. The non-cutting element may include projections, fin-like elements, comb-like features having teeth, exfoliation or lubricating capabilities. By having a fixed non-cutting element disposed midway in a blade array, a multi-stage cartridge is provided with a middle control point with potentially different functionality before and after the non-cutting element. The non-cutting element is not attached to another blade in the blade array though it may be manufactured as a modified blade support, attached to a blade support, or as part of the frame or the clips.

Razor cartridge with non-cutting element

A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has thicknesses of 1.60-1.75 micrometers and 9.25-10.00 micrometers measured at a distance of four and forty micrometers from the blade tip, respectively. A ratio of the thickness measured at four micrometers to the thickness measured at forty micrometers is between 0.165-0.185. The substrate thickness is about 2.70-3.00 micrometers at eight micrometers from the blade tip, about 4.44-5.00 micrometers at sixteen micrometers from the blade tip with a thickness ratio measured at four micrometers and eight micrometers between 0.56-0.62, and a thickness ratio measured at four micrometers and sixteen micrometers between 0.32-0.40. The blade edge shape is defined by equation w=adwhere 'a' is between 0.50-0.62 and 'n' is between 0.76-0.80. An included angle of less than 7&#xb0; is measured at a distance of forty micrometers or greater from the blade tip. A nitrided substrate may also be provided.

A mechanism is disclosed for loading/unloading one or more rechargeable batteries. The mechanism includes one or more charging compartments configured to receive one or more rechargeable batteries and a first actuator configured to cause the one or more rechargeable batteries to be displaced from a first position to a second position.

Battery charger with mechanism to automatically load and unload batteries

A hydrogen generator includes a housing, a solid hydrogen source disposed within the housing, and an inlet configured to guide a fluid to contact the solid hydrogen source. The inlet can contact a wicking region. The wicking region can include a wicking material that has an affinity for the fluid. The wieking material can include a hydrophilic material. The housing can include a hydrogen gas outlet. The hydrogen generator can include an end cap at one end of the housing including the inlet and the hydrogen gas outlet. The hydrogen gas outlet can include a gas permeable membrane. The inlet can be fluidly connected to a fluid control system configured to control fluid flow rate to the solid hydrogen source. The generator can be portable.
