Abstract: Modular skid units that are versatile and easily configurable for particular applications. In some examples, a modular design allows for many different combinations of modular components, such as seats, canine boxes, storage boxes, patient transport units, etc. In some examples, the modular and quick release nature of the system enables users to selectively remove and attach the modular components as needed for a given task, including the ability to quickly and easily change the modular components in the field to meet the specific needs of a mission or task. In some examples, the modular components include quick release locking mechanisms that include a set of locking elements for quickly and easily switching components.

Abstract: A locking mechanism for a quick response fire sprinkler includes an arcuate leaf spring having an inherent radially inwardly directed biasing force being split to provide spaced end portions. A circumferentially extending detent is provided in the peripheral face of the arcuate leaf spring for engaging a circumferential groove provided in the sprinkler valve housing. A fusible temperature responsive element is inserted between the spaced ends of the arcuate spring for spreading the arcuate spring and associated detent radially outwardly into the circumferential groove for holding the sprinkler valve in the closed position. When the temperature responsive element becomes fused, the arcuate leaf spring is retracted radially inwardly from the valve housing allowing the sprinkler valve to open.

Abstract: An exercising device wherein a rotary crank handle mechanism is mounted on the upper end portion of a frame assembly for exercising the upper body portion of a person, and an exercising mechanism is mounted on the lower portion of the frame assembly for exercising the lower body portion of the person. The upper and lower exercising mechanisms are independently operable from each other, and the upper crank handle mechanism is provided with a plurality of adjustment features so that the mechanism can be pivoted to a desired position relative to the frame assembly and the crank arms can be oriented relative to each other to recreate the effects of swimming or rowing.

Abstract: Fire sprinkler head suitable for mounting in a concealed location in the ceiling in a residential dwelling which provides quick and automatic response in the event of a fire. The valve assembly in the sprinkler head is biased to the open mode and is maintained in the closed mode against a positive force, provided by at least the pressurized fire extinguishing fluid, tending to move the valve assembly to the open mode, by a valve closure unit which is separable into its two sections at the onset of a fire.

Abstract: A fire sprinkler head suitable for mounting in a concealed location in the ceiling in a room in a residential dwelling is provided which provides quick and automatic response in the event of a fire. The valve assembly in the sprinkler head is biased to the open mode by means of a positive force, in addition to the force of the fire extinguishing fluid. Nevertheless, the valve assembly is maintained in the closed mode by the valve locking mechanism of the invention until the onset of a fire and the attainment of a predetermined ambient temperature, at which time the locking mechanism is made inoperative. The locking mechanism is maintained in the operative mode until the temperature of the fire melts a heat fusible alloy composition, at which time the locking mechanism or keeper becomes inoperative.

Abstract: Fire sprinkler head suitable for mounting in a concealed location in the ceiling in a residential dwelling which provides quick and automatic response in the event of a fire. The valve assembly in the sprinkler head is biased to the open mode and is maintained in the closed mode against a positive force tending to move the valve assembly to the open mode by a valve closure which is separable into its two sections at the onset of a fire and the attainment of a predetermined ambient temperature surrounding the valve closure. The two sections of the valve closure are maintained intact as a unit until the temperature of the fire melts a heat fusible alloy composition.
