Abstract: Systems and methods for employing non-custodial techniques for data encryption and decryption are provided. One example method includes transmitting, to a first remote server, an encryption request; receiving, from the first remote server, a first response comprising a secret token; generating a first cryptographic signature using the secret token; generating a first cryptographic key based on the first cryptographic signature; encrypting one or more files using the first cryptographic key; and transmitting, to a second remote server, the one or more encrypted files.

Abstract: The present disclosure relates, according to some embodiments, to fluid pump apparatuses. A fluid pump apparatus may comprise a suction compensator, a housing compensator, and a pump. A suction compensator may comprise an ambient fluid compensator, an ambient fluid bladder, and a spring compensator, wherein the spring compensator comprises a first separator partitioning an internal volume of the spring compensator into a first suction fluid chamber and a compensation fluid chamber. A housing compensator may comprise a second separator partitioning an internal volume of the housing compensator into a second suction fluid chamber and a lubrication fluid chamber. The compensation fluid chamber may be in fluid communication with the suction compensator. The first suction fluid chamber may be in fluid communication with the second suction fluid chamber. A pump may comprise a housing defining a lubrication fluid compartment in fluid communication with the lubrication fluid chamber.

Abstract: A method of increasing the likelihood an electronic message will be opened by a targeted recipient includes determining a time zone corresponding to an address of a targeted recipient and accessing an opening history for a set of electronic mail recipients within a domain including the targeted recipient. From the time zone and the opening history at least one of a time and a day are recommended for sending an electronic message to the target recipient to increase likelihood that the electronic message will be opened.

Abstract: A power generation system comprises a turbine and a fluid warming device in communication with the turbine. The fluid warming device may comprise a housing, an inlet pipe carried by the housing, an outlet pipe carried by the housing, and a plurality of solar collection members carried by the housing between the inlet pipe and the outlet pipe. The plurality of solar collection members may have a plurality of channels to receive fluid. The inlet pipe, the plurality of solar collection members, and the outlet pipe are in fluid communication with one another.

Abstract: An energy transfer system includes an energy transfer device, a water inlet pipe and a water outlet pipe. The water inlet pipe may be connected to a water inlet of the transfer device to extract water from a water source. The water outlet pipe may be connected to a water outlet on the energy transfer device to discharge water to the water source. The water inlet pipe may extract water from a predetermined extraction depth, and the water outlet pipe may discharge water into the water source at a predetermined discharge depth.

Abstract: A fluid-containing brush has a housing (11) with a generally cylindrical wall closed at one end by a base carrying brush bristles (25) and at the other by a cap (50) formed of resilient material, the housing defining a fluid reservoir, the base having a central opening therein closed by a valve member for dispensing liquid to the brush bristles, and a valve stem (31) which extends up to an underside of the cap (50) the housing and cap being adapted to provide a fluid tight seal therebetween, and the cap having a deformable portion constituting a button (58) by which the user can actuate the valve to dispense cleaning fluid.

Abstract: A fluid-containing brush (10) has a housing (11) with a generally cylindrical side wall (12) closed at one end by a base (20) carrying brush bristles (25) and at the other by a removable cap (50). The housing (11) defines a fluid reservoir and the base (20) has a central bore (21) therein closed by a valve member (32) for dispensing liquid to the brush bristles (25). A valve stem (31) extends up to an actuator button (58) formed on the cap (50). The button (58) is made of elastomeric material and is used to actuate the valve to dispense cleaning fluid. A sealing ring (64) is provided between the cap (50) and housing (11) to ensure a fluid tight connection between the cap (50) and the side wall (12).

Abstract: A substantially circular, round lifeboat provided with a flat bottom surface and upwardly curved sides, the interior of the boat being provided with a series of concentrically arranged seats for the passengers, mostly near the bottom of the boat to provide a low center of gravity, the boat having a fiber glass hull and a fiber glass covered styrofoam interior in order that it be strong and sturdy, while being relatively light in weight, with the capability of each boat being molded in two pieces (hull section and seat and rib section) and joined together, the upper perimeter of the boat having a plurality of spaced-apart arms for supporting transparent plastic panels which extend upwardly and thus increase the free-board, the arms also providing support for a plurality of curved supporting ribs arranged in a dome-shaped fashion to support a suitable cloth material to form a complete cover for the open upper portion of the boat.

Abstract: A construction system for buildings of the one-story or multi-story type which includes prefabricated elements comprising preformed panels for outside walls, floors, roofs and partitions together with metallic angle members for supporting floor and roof panels from the said wall panels, the system including pre-drilled holes in the panels and angle members for the reception of fastening devices, to the end that the erection of a building structure may be effected with the use of the foregoing preformed components in a simple, efficient and convenient manner and with a minimum of skilled labor.

Abstract: In the production of stable dispersoid titanium, carbide strengthened copper by fusion metallurgy, refractory dispersoid particles are formed in situ within the copper melt by reaction between specifically selected components including nickel within the melt. The components are characterized by novel wetting relationships, by which the refractory dispersoid is maintained as such within the melt. The resulting composite material has been found to have an unusual association of high electrical conductivity and high temperature strength, by virtue of which novel electromechanical switches and the like are possible.
