  • Gas treatment element and a method of forming a gas treatment element
    Patent number: 12239938
    Abstract: A method of forming a gas treatment element for use in a gas treatment apparatus, such as a desiccant dryer, is disclosed. The element is formed by casting a sheet material by phase inversion of a dope mixture including a solvent, an adsorbent material such as a desiccant and a polymer binder. Layers of the sheet material are located adjacent one another and this is most readily achieved by rolling the sheet material to form the gas treatment element.
    Type: Grant

  • A HYDRAULIC TORQUE WRENCH
    Publication number: 20190358793
    Abstract: A hydraulic torque wrench is disclosed and includes a nut engaging portion with ratchet teeth on an external surface thereof. There is also a support member which can rotate relative to whilst retaining the nut engaging portion. A ratchet mechanism cooperates with the ratchet teeth to apply a rotational force to the nut engaging portion as a result of the pushing force from a hydraulic ram. Side plate cover a junction between the nut engaging portion and the support member with the side plates having a noncircular aperture through which a nut and bolt can extend when the wrench is in use.
