  • Patent number: 11938499
    Abstract: The present invention provides unique pressure actuated valves and related methods that may be used in applications where a plurality of fluid emission devices are provided on a plurality of lines containing fluid under pressure, in order to prevent fluid from escaping from the fluid emission devices until a consistent threshold or predetermined level of fluid pressure is obtained in the lines, without causing significant water pressure and/or flow loss through the valves. Valves of the present invention include a housing having an upper body and a lower body that may be coupled together to form an inner chamber, the lower body having an inlet in communication with a source of fluid under pressure, the upper body having an outlet in communication with a fluid emission device. A hollow movable fluid transmission piston is provided in the chamber for communicating between the inlet and outlet.

  • Patent number: 11602760
    Abstract: A showerhead that is attached to a shower arm which extends outward from a wall in a shower to support a base and/or a mirror. The base is provided for decorative purposes or to support the mirror. The mirror provides a mirrored surface that can be utilized by a person taking a shower to more safely, efficiently and effectively shave and/or accomplish other grooming tasks. The mirror attaches to the base, directly to the showerhead or to a tubular post that interconnects the showerhead and the base or mirror. Water from the showerhead discharges adjacent to the mirror. In either configuration, the mirror is more securely positioned in the shower so it will not drop to the shower floor. Hot water flowing through the mirror reduces fogging of the mirrored surface. In one configuration, the base is made out metal to further reduce the likelihood of fogging.

  • Patent number: 10603402
    Abstract: This invention claims hot melt adhesive compositions that can be used to form elastic composites that are useful in disposable absorbent articles. The compositions have good elastic recovery and high peel adhesion at a viscosity of less than about 20,000 cps at 177° C. The low viscosity makes it possible to apply the adhesive at a high line speed and target application to only those areas requiring elastic performance.
