  • Patent number: 10440872
    Abstract: An adjustable hand trowel comprising a handle, a blade-neck assembly comprising a blade and a neck, and an adjustable fastener system is disclosed herein. The adjustable fastener system provides a secure method of fastening the blade-neck assembly to the handle wherein the adjustable hand trowel is able to withstand forces typically exerted when using a trowel for digging and wherein the user may readily dig in confined spaces. The disclosed adjustable hand trowel further allows a user to adjust the relative position of the blade and handle using an adjustable fastener system that may be operated using one hand. The adjustable hand trowel may thereby allow the user to dig in an ergonomic and efficient manner in applications that would otherwise be unsuitable for ergonomic and efficient digging.

  • Patent number: 9015980
    Abstract: The present disclosure provides a gun having an off-hand grip adjustably coupled to a handguard and spaced apart from a grip with a trigger located between the grip and the off-hand grip. The off-hand grip has a first end and a second end that is distal from the first end. The off-hand grip includes a pivot located adjacent the first end such that the off-hand grip is pivotable with respect to the handguard. The off-hand grip is also pivotable between a use position where the off-hand grip longitudinally extends about transverse from the barrel, and a stowed position where the off-hand grip is longitudinally adjacent the barrel.

  • Patent number: 7562664
    Abstract: Several products and processes for preventing the occurrence of rust stains resulting from irrigation systems using water having iron ions, such as well water, and for cleaning off rust stains resulting from the use of said irrigation systems are disclosed. In one embodiment, ammonium sulfate is mixed with well water and then this mixture is mixed with incoming well water being sprayed on the surfaces. In another embodiment, ammonium bisulfate is used for the removal of rust stains. Then ammonium sulfate is mixed with the incoming well water being sprayed in the next cycle, to prevent rust formation.

  • Patent number: 6591732
    Abstract: A method and device for cooling a gun barrel wherein coolant is provided to the gun barrel via a nozzle arranged at the downstream end of a pressure feed line arrangement. The coolant is originally conveyed from a reservoir into a pressure cylinder, while the pressure feed line between the pressure cylinder and the nozzle is closed. Thereafter, the coolant in the pressure cylinder is placed under a predefined operating pressure. Prior to firing a round, the pressure feed line is opened, so that the coolant flows to the gun barrel before firing. When firing a shot, the coolant in the gun barrel is compressed to a pressure above the predetermined operating pressure by the firing gases and pushed out of the gun barrel. In the process, the coolant is expanded into a buffer reservoir adjacent to the nozzle and is injected back into the gun barrel after the gas pressure built up has been reduced to the predetermined operating pressure.
