  • Publication number: 20190076993
    Abstract: The main fixed handle optionally incorporates two swivel out arms, which can form part of a three-legged base. When operated thus, the jaws and moving handle point generally upwards from the formed base, the moving handle can now be operated by one hand leaving the other free to position the workpiece. The moving handle can incorporate a further locking switch that can be utilised in both a switchable locking position or non-locking position upon a sprung toothed strut between the handles, at least one of which further incorporates a curved resilient portion in order to provide useful sprung closure of the parallel moving jaws upon the workpiece in the locking method. A lanyard can be optimally attached to the swivel out arm ends to provide the user with a chest mounted portable vice.

  • Publication number: 20190022831
    Abstract: A ratchet wrench (1) is designed such that a clutch ring (500) forms the mid part of an extremely strong laminate like structure. Under torque conditions the compression forces applied to the clutch ring (500) are substantially dissipated around its circumference (507) and inner surface (508), this inward force clamping upon the inherently strong drive outer surface (405). The resultant pseudo laminate like construction of the drive element (400), clutch (500) and housing (201, 202) enables a proportionately stronger ratchet wrench 1 of much reduced depth. The drive element (400) may be used with interchangeable inserts (408).

  • Publication number: 20190015958
    Abstract: A locking clutch ratchet wrench (1) is configured such that a clutch ring (500) forms the mid part of aminate like structure. Under torque applying conditions, the compression forces applied to the clutch ring (500) are substantially dissipated around the circumference (507) of the clutch ring. This inwardly directed force clamp against the inherently strong outer surface (405) of the drive element (400). The resultant pseudo laminate structure of the drive element (400), clutch (500) and housing (201, 202) enables the construction of a proportionately stronger ratchet wrench of reduced height or width.

  • Publication number: 20190015957
    Abstract: The ratchet (1) is designed such that the flexible clutch ring (500) forms the mid part of an extremely strong laminate like housing (200) structure, under torque conditions the resultant compression forces applied to the clutch ring (500) are substantially dissipated around its circumference (507) and inner surface (508), this inward force clamping upon the inherently strong drive outer surface (405). The resultant pseudo laminate like construction of the drive (400), clutch (500) and housing (201, 202) enables a proportionately far stronger reduced width ratchet (1).

  • Publication number: 20190009394
    Abstract: A ratchet wrench (1) has a flexible clutch ring (500) that forms the mid part of a laminate-like structure comprising a wrench head (200), the clutch ring (500) and a drive element (40). When under load, the compression forces applied to the clutch ring (500) are substantially dissipated around its circumference (508) and inner surface (509), this inward force clamping upon the inherently strong drive outer surface (45). The laminate-like construction enables a reduction in the width or depth of the wrench head without a loss in strength.

  • Patent number: 9593625
    Abstract: An internal combustion engine has a chamber that has a longitudinal centerline, inlet valving operable to admit constituents of a combustible mixture into the chamber for combustion in the chamber to provide a pressure increase in the chamber and outlet valving operable to release an outflow of liquid from the chamber under an influence of the pressure increase. An annular flow passage is defined in the chamber to conduct liquid towards the outlet valving and cause spiraling of the liquid in the flow passage by which a rotatable part exposed to the spiraling flow is caused to rotate. An electrical generator disposed externally of the chamber is driven by rotation of the rotatable part.

  • Patent number: 9371732
    Abstract: An internal combustion engine includes a chamber and inlet valving operable to admit constituents of a combustible mixture into the chamber for combustion therein to provide a pressure increase in the chamber. First input valving admits a liquid into the chamber and a control system controls the first input valving such that the liquid is admitted to the chamber to compress at least one constituent of the combustible mixture. Outlet valving releases an outflow of the liquid from the chamber under an influence of the pressure increase as an energy output of the chamber. Second input valving selectively admits a heated aqueous fluid into a region of the chamber in which combustion of the combustible mixture occurs to promote a hydrogen separation process in the chamber to provide hydrogen that is combusted in the chamber. A supply system supplies the heated aqueous fluid to the second input valving.
