Abstract: A portable steam generator includes a power source in a housing, a water tank in the housing, a heating element in the housing and configured to heat water in the water tank to produce steam using power from the power source, and a track on the housing configured to support the portable steam generator in an installation position and allow manual removal from the installation position. A pre-plumbed integrated bathroom panel includes a plumbing inlet configured to provide water to the panel, a water outlet connected to the plumbing inlet, a steam outlet connected to the plumbing inlet and a heating element, a sanitizing outlet connected to the plumbing inlet and an additive generator, valves for directing water from the plumbing inlet to the at least one water outlet, the at least one steam outlet, and the at least one sanitizing outlet, and a controller configured to operate at least the plurality of valves.

Abstract: A new method of manufacturing a dual investment reticulated solid mold for producing reticulated metal foam, that includes 3D printing of a wax or resin reticulated precursor prior to pre-investment with a pre-investment plaster or pre-investment ceramic plaster, and removal of the precursor before addition of liquid metal to generate reticulated metal foam.

Abstract: A method of enhancing an open celled foam metal heat exchanger is presented where the structure uses fluid channels that distribute fluid and/or air across a continuous flow field. The heat exchanger not only improves heat transfer properties given a required pressure drop but also takes into consideration the need to manufacture low cost solutions that may be mass produced to meet high capacity throughput requirements for the air and space industries.

Abstract: Heterogeneously dense (relative density) continuous one-piece insoluble reticulated foam material with a continuous relative density gradient and/or distinct and marked relative densities and methods of manufacture.

Abstract: A coin chute construction for a dispensing machine and method of making same are provided wherein such machine requires at least one coin of predetermined size and valuation to initiate one operation of the machine for one item of goods or service. The construction comprises improved structural components associated with holding, moving, and testing each coin at a test station; and a coin knockout device which prevents a coin jammed in a slider of the machine from being used to provide more than one operation of such machine.

Abstract: A coin chute construction for a dispensing machine and method of making same are provided wherein such machine requires at least one coin of predetermined size and valuation to initiate one operation of the machine for one item of goods or service. The construction comprises cooperating structural components for providing movement of the coin away from and then back toward a rectilinear path during movement of a slider of the construction which carries such coin from an inoperative position to a test position for the coin prior to initiation of the one operation of the machine.

Abstract: A lock box and method of making same are provided wherein such lock box is mountable in an aperture of a cabinet wall and comprises; a coin receptacle dimensioned for passage through the aperture and having an open top and a front wall portion; a face member having a bore therethrough, a peripheral edge, and an inside surface; removable fasteners for fastening the receptacle to the face member by fastening the front wall portion thereto; at least one locking bolt carried by the face member and being movable to extended and retracted positions relative to a portion of the peripheral edge of the face member to engage a portion of the cabinet wall and fasten the lock box thereto upon extension of the bolt; a lock assembly carried by the face member and provided for operating the bolt with the lock assembly being accessible by a key through the bore; and the lock box includes dual purpose components for supporting the entire lock assembly inwardly of such inside surface and protecting same against removal thereof

Abstract: A hardened protective housing is rotatably secured to the outer head of a cylindrical lock for precluding access to and mistreatment of said head for rendering the lock ineffective for its intended purpose.

Abstract: A coin testing device includes one or more coin-receptive slots of specific depth, height and width for testing the flatness, thickness and diameter of like, "on-edge" coin-tokens which pass therethrough, and a rearwardly declining deck projecting from the slots for receiving and advancing acceptable coin-tokens, wherein a guide member is disposed upwardly from and substantially parallel to the deck for engaging the peripheral edge adjacent face of acceptable coin-tokens for testing the peripheral configuration thereof, wherein ultimately accepted coin-tokens are advanced across the deck and are guided by the guide member into coin-receptive discharge apertures which are disposed at substantially right angles to the slots.

Abstract: A reciprocable slide actuator is movable between fully retracted and fully advanced positions, wherein a latch is selectively engageable with the slide actuator to preclude advancement thereof from a retracted position. Control means are selectively operable to disengage the latch from the slide actuator for permitting advancement of the slide actuator to the fully advanced position.

Abstract: A coin-actuated circuit-closing device includes a coin chute into which a predetermined number of like coins must be inserted to initiate the closing of a normally-open electrical control circuit. The device is responsive to introduction of a predetermined number of like coins into a coin-receptive chute to close the normally-open electrical control circuit, and is operable upon closing of the control circuit to reopen same.

Abstract: An inclined coin chute includes devices for testing the ferrous content of, the weight of, and the presence or lack of a central aperture in coin-tokens which are present in and advancing through the coin-receptive chutes of the inclined coin-chute, wherein the testing devices are operable to intercept and eject spurious coin-tokens from the coin-chute.
