  • Patent number: 10928113
    Abstract: A system and method for generation of hydrogen-rich ice (HRI) by introducing water that has been mixed with H2 and CO2 into the vertical tubes of a tube-ice machine is disclosed. The temperature and pressure within the vertical tubes can be maintained by refrigerant surrounding the vertical tubes to form carbon dioxide clathrate hydrates which entrap hydrogen molecules. The carbon dioxide clathrate hydrates cages with entrapped H2 are encased, transported and then delivered after HRI discharge Later, when the HRI tube-ice is formed and released from tube-ice machine, it warms whereupon the carbon dioxide clathrate hydrates dissociate and the H2 is released and used, for example by placement of the tube-ice small cylinders in a glass of water.

  • Patent number: 10884199
    Abstract: A first optical axis of a first optical component is caused to be at a first angle with respect to a first precision surface of the first optical component. A second optical axis of a second optical component is aligned to be at a second angle to a second flat surface of the second optical component. The second angle is equal to or derived from the first angle. The first and second flat surfaces are caused to directly face each other to allow only sliding motion between the first and second flat surfaces. The sliding motion is performed between the first and second flat surfaces until the first and second optical axes are sufficiently collinear.
