A recessed lighting fixture providing illumination from a light source comprising a plurality of light emitting diodes (LEDs) placed within a cavity of a planar surface, such as a ceiling, wall, or shower. The fixture comprises a baffle integrated with a low profile heat sink that is used to draw heat out of the fixture and communicate that heat to a trim ring of the fixture for dissipation of the heat in the room so that higher intensity light sources can be used. Improved grounding of the recessed trim unit to the recessed housing is provided with combination support and grounding springs. One embodiment of the light source is fixed in position while a second embodiment is gimbal mounted for aiming the light produced by the fixture.

The side plate includes a heat dissipating part in which a plurality of heat dissipating holes is defined. The adjusting piece is movable with respect to the heat dissipating part for covering portions of at least some of the heat dissipating holes. The enclosure provides a function of adjusting of heat dissipation and noise suppression of an electrical system.

Projectile apparatus is provided employing light and sound that may be dispersed over a large area with high intensity to produce a non-lethal, visible and audible countermeasure to temporarily blind and / or disorient one or multiple potential adversaries. The apparatus is suitable for use in tactical scenarios by military, police, and special operations personnel. The apparatus is also suitable for use in training operations for military, police, and special operations personnel. For amusement or recreation, the apparatus may be used in simulated warfare or in games such as paintball.

A rotational obstruction and beacon signaling apparatus, in which chip-on-board (COB) packaged light emitting diodes (LEDs) are employed to provide a flashed emission pattern with high luminous intensity. The flash sequence of individual LEDs is controlled by an electronic timing circuit to simulate a rotational or other motional signaling effect.

An electrical generator has an internal combustion engine and an alternator mounted to the engine and operative to generate electrical power during running of the engine. The alternator and the engine are arranged vertically to reduce the footprint of the electrical generator. The components of the electrical generator are contained within an enclosure defined by a base panel, a set of upright side panels, and a roof panel. When the roof panel is removed, each of the side panels can be independently removed from engagement with the base panel, which allows for easier access to the components of the electrical generator, such as for maintenance, service, and repair. The components are arranged so that cooling and exhaust air flow paths are defined within the enclosure.

The invention provides a closed chamber typed heat exchanger, belonging to the heat energy exchange technical field. The closed chamber typed heat exchanger is characterized in that a hole plate is sealed with two ends and the circumference of a cylindrical shell which is horizontally arranged; a cold fluid heat exchange pipe bundle and a hot fluid heat exchange pipe bundle pass through the hole plate and are sealed to form a chamber body; the cold fluid heat exchange pipe bundle and the hot fluid heat exchange pipe bundle are respectively arranged in the upper space and the lower space of the chamber body; a vacuum-shaped closed chamber is filled with working media; the internal chambers of the cold fluid heat exchange pipe bundle and the hot fluid heat exchange pipe bundle are communicated with a cover with a connecting pipe at two ends so as to respectively form an independent fluid passage; an installation supporter is welded externally below the cylindrical shell; the closed chamber of the cylindrical shell can be provided with a plurality of structural types such as single body, double bodies or three bodies; the closed chamber typed heat exchanger has the active effects that the heat exchanger is not a pipe shell typed heat exchanger in traditional meaning and has the advantages of simple structure, fast response, convenient heat control, high heat transmission efficiency and obvious energy-saving effect. The heat exchanger can be applied to heat transmission places with low, middle and high temperature, and is an extremely practical invention.

A novel waterborne cultivator, which provides the benefits of known systems for culture of photosynthetic micro-organisms in a novel configuration, incorporating a simplified, two-phase rotary mixing and gas injection system, the two phases being liquid and gas (CO2). The mixing system provides optimum growth conditions through increased turbulent vertical mixing and increased levels of dissolved CO2 throughout the cultivator via injection of flue gas or other CO2-bearing gas stream. The system thus provides efficient capture and sequestration or reuse of CO2 while producing valuable biomass for food, feed, and fuel use. The waterborne configuration provides further benefits of passive temperature control and automatic leveling for consistent culture depth. Additional benefit is provided by an enclosed design which reduces contamination and evaporative loss by isolating the photosynthetic culture from the outside environment. The simplified and well-integrated design of the cultivator and mixing system greatly reduces capital and operating costs compared to previously known systems.
