Abstract: The subject technology may be implemented by a device that includes at least one processor configured to encrypt a data object based at least in part on an encryption key. The at least one processor may be further configured to sign the encrypted data object with a private key and transmit the signed encrypted data object to a server for retrieval by another device. The at least one processor may be further configured to generate a sharing object corresponding to the data object, wherein the sharing object includes an encryption key and a public key that corresponds to the private key. The at least one processor may be further configured to encrypt the sharing object using a key of the other device and transmit, over a secure channel, the encrypted sharing object to the other device for subsequent retrieval and verification of the signed data object from the server.

Abstract: A drum sander having a fin for deflecting airflow around the drum and directing dust and debris to a dust collecting outlet. The fin includes a first section at a first angle and a second section at a second angle that directs air movement generated by the operating drum toward the dust collecting outlet. The free edge of the fin is shaped to wrap partially around the drum in two helical inclined planes. A tool free adjustment of parallelism may be provided. The workpieces are pulled through the sander rather than being pushed through. Lightweight materials reduce stress on the assembly. Heat is dissipated by the configuration and material of the drum.

Abstract: Techniques are disclosed relating to protecting branch prediction information. In various embodiments, an integrated circuit includes branch prediction logic having a table that maintains a plurality of entries storing encrypted target address information for branch instructions. The branch prediction logic is configured to receive machine context information for a branch instruction having a target address being predicted by the branch prediction logic, the machine context information including a program counter associated with the branch instruction. The branch prediction logic is configured to use the machine context information to decrypt encrypted target address information stored in one of the plurality of entries identified based on the program counter.

Abstract: The present disclosure includes a centrifuge system for processing a massecuite composition. The centrifuge system may include a centrifuge having a vertical spindle, a housing, and a basket disposed within the housing. The basket may include a central hub coupled to the vertical spindle for rotation therewith, a cup coupled to the central hub or an end of the vertical spindle, and a loading cone positioned over the cup and coupled to the cup by a plurality of vanes extending outward from the cup to the loading cone. The loading cone may have a wide end open towards a bottom of the basket, and the plurality of vanes may be radially spaced apart. The centrifuge system may further include a feed pipe vertically disposed above the cup and having a feed outlet oriented towards the cup. The cup defining a cavity oriented in a direction away from the central hub.

Abstract: A system includes a cold plasma applicator configured to couple directly to a container, wherein the cold plasma applicator is configured to generate a cold plasma within the container. A method includes operating a cold plasma applicator to generate a cold plasma to treat contents within a container, wherein the cold plasma applicator is configured to directly couple to the container, or the cold plasma applicator comprises a varying geometry application surface having a plurality of protruding electrode portions spaced apart from one another to define a plurality of intermediate recessed portions, or a combination thereof.

Abstract: A blade clamp with first and second gripping members configured to hold a cutting blade, a lever connected to the clamp by a connection member, and a head that receives the connection member that extends through an aperture of the head. The connection member can move along a first axis through the aperture of the head and move the clamp along the first axis based on a position of the lever. The first and the second gripping members of the clamp can clamp the cutting blade along a second axis orthogonal to the first axis based on a position of the clamp along the first axis. The lever can include an eccentric cam surface that engages a cam follower. The eccentric cam surface can cause the clamp to provide a clamping force and tension to the cutting blade.

Abstract: A blade guide for a band saw tool includes an adjustment channel mounted to a blade housing. The adjustment channel has a bracket plate with two recesses at an angle to one another. A roller bracket has a ridge that fits into one or the other recess, the roller bracket including rollers to guide the band saw blade. A single screw holds the roller bracket to the bracket plate. The roller bracket may be moved to the other recess to impart a twist to the blade. The blade is used without a twist when the band saw tool is configured for vertical cutting and is used with a twist when the band saw tool is configured for horizontal cutting.

Abstract: A band saw that is convertible between a vertical cutting position and a horizontal cutting position includes a work table extension that extends from a work table when the band saw is used in the horizontal cutting position. The work table extension is removable from the work table and is attachable to a blade guide when the band saw is used in the vertical cutting position.

Abstract: An overload indicator for a hoist includes first and second blocks that connect to the lifting medium (a chain for a chain hoist) at spaced locations. The first and second blocks are held at a spacing by indicator bands so that the lifting medium is slack between the blocks. The indicator bands have weakened portions to deform, stretch or break when subject to a load over a threshold, such as over a lifting capacity of the hoist. Covers are provided over the indicator bands that are closely spaced to define an indicator gap. If the indicator bands stretch, the indicator gap increases to indicate an overload condition.
