Abstract: A storage case assembly includes a first member with at least one male hinge member and at least one female hinge member; a second member with at least one male hinge member and at least one female hinge member; and at least one latch member that connects the first member and the second member, wherein the first member and the second member are identical.

Abstract: A firearm receiver assembly includes a receiver body, a threaded mount at a rear portion of the receiver body, a magazine release assembly including a magazine release portion on at least one side of the receiver body, a bolt release assembly including a bolt release central portion and a bolt release portion on at least one side of the receiver body, and a safety selector assembly including a safety portion on at least one side of the receiver body. The bolt release central portion translates vertically within a cavity of the receiver body.

Abstract: A blockchain system may include nodes, member network entities, and a protocol entity. The nodes together are configured to maintain an immutable record as a blockchain, based on commands provided by the protocol entity. A member may provide a request for a transaction to the protocol entity to perform an operation along with encrypted data. For example, the operation may include a transaction. The protocol entity may invoke a smart contract at one or more nodes to perform the operation on the encrypted data. In response, the node decrypts the encrypted data using a decryption key stored in the node storage equipment to generate cleartext data. The node then performs the operation based on the cleartext data and secures the cleartext data. The immutable record of the blockchain to be updated based on the operation. For example, the secured data and audience permission information may be added to the blockchain.

Abstract: A versatile hair covering holds dreadlocks or other large amounts of hair in a way that creates the appearance of a crown yet is practical since it snugly holds the hair and keeps it away from the face. Its versatility allows it to be worn as a hat or under a hat. The hair covering is made of six five-sided panels of stretchable fabric whose bottom edges are stitched to an annular band of fabric having an elastic insert.

Abstract: Disclosed herein is a technique of prospecting for deep massive sulphide ore bodies, comprising the steps of selecting a geologic region which is substantially acoustically transparent; directing seismic waves at the region and collecting reflected or diffracted waves therefrom; and analyzing the collected waves for the presence of the massive sulphide ore bodies.
