  • Publication number: 20240118022
    Abstract: The present invention relates generally to an apparatus and method of rapidly and efficiently cooling a liquid, wherein flow is induced via gravitational feed from a reservoir, through a cooling chamber, further in connection to a refrigerant source wherein said liquid exits through an inferior actuatable outlet and said refrigerant is released through an exit valve. Specifically, the present invention allows for the rapid cooling of an alcoholic liquid through contactless exposure a carbon dioxide refrigerant source whereby said liquid and refrigerant occupy separate, non-communicating chambers.

  • Publication number: 20230199932
    Abstract: A device (1) controllable by a short-range point-to-point radio frequency signal, e.g. a Bluetooth signal from a mobile device (23), is configured to receive, e.g. from the mobile device and neighboring lighting devices (11-12), one or more signals which comprise the short-range point-to-point radio frequency signal, determine changes in received radio frequency signals from the one or more signals, detect presence, e.g. of a resident (51), based on the changes, determine a control command from the short-range point-to-point radio frequency signal, and execute the control command in dependence on the presence being detected.

  • Patent number: 7147032
    Abstract: In a process for the assembly of wax trees, a wax runner is placed in a flat position, and a wax pattern is located adjacent to the wax runner. Both the wax pattern and the wax runner are heated and then placed in contact with one another where heated. Then the wax pattern and the wax runner are separated slightly to form a fillet weld between the wax pattern and the wax runner. An apparatus is also provided which, by robotics, brings a multiplicity of wax patterns to a wax runner and which automatically heats both the wax patterns and the wax runner before simultaneously pressing both the wax patterns and the wax runner together. Once a wax tree assembly is completed, a new wax runner replaces the wax runner that has been formed into a wax tree, and additional wax patterns are affixed in the same manner.

  • Patent number: 6991430
    Abstract: A turbine blade squealer tip has a continuous squealer tip wall extending radially outwardly from and continuously around a tip cap. A recessed tip wall portion of the tip wall is recessed inboard from a pressure side of an airfoil outer wall of an airfoil of the blade forming a tip shelf therebetween. A plurality of film cooling shelf holes are disposed through the tip shelf to an internal cooling circuit of the blade and are spaced away from a junction between the recessed tip wall portion and the tip shelf. The exemplary embodiment of the airfoil includes shelf hole centerlines of the holes passing through pierce points in the shelf. At least a majority of the shelf hole centerlines are angled in outboard directions away from and outboard of the squealer tip wall. A majority of centerlines are angled away from vertical lines passing through the pierce points at first component angles in a range between 2 degrees and 16 degrees.

  • Patent number: 5680063
    Abstract: A bi-directional voltage translator (102) includes a first port (300/302), a second port (302/300), and a switch circuit (310). The first port (300/302) communicates a first signal at a first voltage or a second voltage (V.sub.1 /V.sub.2). The second port (302/300) communicates a second signal at the first voltage or a third voltage (V.sub.2 /V.sub.1). The second and third voltages (V.sub.1 /V.sub.2) are different. The switch circuit (310) is coupled to the first port (300/302) and the second port (302/300). The switch circuit (310), responsive to the first signal at the first voltage and the second signal at the third voltage (V.sub.2/ V.sub.1), communicates to the second port (302/300) the second signal at the first voltage. The switch circuit (310), responsive to the second signal at the first voltage and the first signal at the second voltage (V.sub.1 /V.sub.2), communicates to the first port (300/302) the first signal at the first voltage.
