Abstract: A vacuum insulated cabinet structure includes panels having sheet metal outer side walls and polymer inner side walls. The polymer inner side walls are heat-sealed to a layer of polymer material laminated to a flat sheet metal blank to form vacuum cavities. The blank is then bent along fold lines to form a cabinet structure.

Abstract: A missile includes a rocket motor that has a flow deflector in an expansion region of the rocket motor's nozzle. The flow deflector diverts flow of combustion products away from a safe region that is aft of the missile. The safe region protects an operator of a launcher used to fire the missile, such as a shoulder-fired launcher, from harm caused by the combustion products. The flow deflector may be small enough such that it does not significantly adversely affect the performance of the rocket motor. The presence of the flow diverter may allow for the rocket motor to be started sooner in the flight of the missile, or at a distance closer to the operator, while still keeping the operator safe. The flow deflector and supporting structure, such as struts, may be additively manufactured with at least an aft part of the nozzle, as a continuous single-piece part.

Abstract: The present invention provides improved devices for removing energy and fluid from body fluid containing spaces and surfaces of a mammal, the devices including isolated air and water delivery systems configured to simultaneously deliver streams of dry air and liquid water to the nostrils of a patient, without allowing the streams to come into contact with one-another until it enters the patient's nostrils.

Abstract: Delivery landing pads for unmanned aerial vehicles (UAVs) are disclosed. A disclosed landing pad to support a UAV includes a landing surface, and a pressure sensor operatively coupled to the landing surface. The landing pad also includes a processor to determine a presence of the UAV on the landing pad and calculate a weight of a payload transported by the UAV based on a measurement of the pressure sensor to determine whether the payload has been delivered to the landing pad.

Abstract: A dual tire buffing apparatus includes a turntable having a first end and an opposite second end. The turntable is rotatable about a central axis between first and second positions. A first expandable hub is rotatably coupled to the turntable proximate the first end. The first expandable hub is configured to receive a first tire casing. A second expandable hub is rotatably coupled to the turntable proximate the second end. The second expandable hub is configured to receive a second tire casing. A rasp head is positioned to operatively engage the first tire casing on the first expandable hub when the turntable is in the first position to perform a buffing operation on the first tire casing, and to operatively engage the second tire casing on the second expandable hub when the turntable is in the second position to perform a buffing operation on the second tire casing.

Abstract: A motor assembly is provided for use with projectiles, such as munitions, having relatively low length to diameter ratios. The motor assembly has an aerospike nozzle and a casing disposed about the aerospike nozzle, where interior aerospike volume contains propellant and where walls of both the cowl of the casing and of the aerospike nozzle jointly define a combustion chamber.

Abstract: Systems and methods of buffing tire casings are provided. A tire buffing machine includes a tire hub assembly selectively rotating a mounted casing, a buffer configured to buff the casing, a tire belt detection apparatus having two or more sensors to detect a first belt depth of one or more belts at a first lateral position in a tire casing and a second belt depth of the one or more belts at a second lateral position within the tire casing, and an electronic controller. The controller determines the first belt depth and the second belt depth using a belt detection apparatus having two or more sensors of the belt detection apparatus and adjusts the operation of the buffer based on the first belt depth or the second belt depth.

Abstract: A laundry system performs a washing function to wash multiple load of fabric items. The system can include a first wash chamber for washing a first clothes load, a tub, and a wash basket rotatably mounted within the tub and defining a second wash chamber, which has a low capacity relative to a capacity of the first wash chamber. The laundry system is capable of performing a washing operation in the second wash chamber independently of a washing operation performed in the first wash chamber.

Abstract: A laundry system performs a washing function to wash multiple load of fabric items. The system can include a first wash chamber for washing a first clothes load, a drawer below the first wash chamber, a tub supported by the drawer, and a wash basket rotatably mounted within the tub and defining a second wash chamber, which has a low capacity relative to a capacity of the first wash chamber. The laundry system is capable of performing a washing operation in the second wash chamber independently of a washing operation performed in the first wash chamber.

Abstract: A gas generation system for generating gases, such as for use as or as part of a rocket motor in propelling a projectile, includes two or more propellant charges and electrically operated propellant initiators operatively coupled to respective of the propellant charges, to initiate combustion in the propellant charges, wherein the propellant charges are operatively isolated from one another such that the propellant charges can be individually initiated and are not ignited due to gases generated from other of the propellant charges being combusted.
