A light emitting diode (“LED”) module with improved thermal characteristics is provided. The module includes an LED, a first circuit board, a second circuit board, a lower insulator, an upper insulator, a lower contact, upper contacts, and a heat sink. Preferably, the heat sink comprises an outer housing and a contact ring. The LED and the heat sink are attached to the first circuit board via solder. In addition to serving as a substrate for the LED, the first circuit board (which contains a plurality of thermally conductive layers connected by vias) facilitates the transfer of heat away from the LED to the heat sink. The module also has improved mechanical and electrical properties, including redundant electrical connections, stable mechanical connections, and a shock-absorbing lower contact. The lower insulator can also be configured to prevent misalignment of the power source with the lower contact when the module is used in a flashlight or other lighting device.

A catch engagable with a catch pivot ring for capturing and releasing a stunning rod moveable along a longitudinal axis in a pneumatic animal stunner for stunning an animal. The catch comprises a plurality of arcuate sections substantially forming a cylinder, each arcuate section having a forward end and a rearward end. The catch includes an inner wall toward the longitudinal axis and an outer wall away from the longitudinal axis. The catch includes a flange at the rearward end of the arcuate section extending outwardly directly from the outer wall and away from the longitudinal axis and a lip at the forward end of the arcuate section extending inwardly from the inner wall and toward the longitudinal axis. Each of the arcuate section flanges is engagable with an inner lip of the catch pivot ring allowing the arcuate sections to pivot about the catch pivot ring inner lip.

A pneumatic stunner for stunning an animal has a piston slideable within an inner chamber, and a stunning rod driven by the piston forward and rearward towards and away from the front end of the housing. The stunning rod has an elongated body having a longitudinal axis and a detachable hardened tip. The density of the material comprising the elongated body is less than the density of the material comprising the detachable hardened tip.

A controller for a vacuum contactor or the like measures barometric pressure and provides a short impedance characterizing pulse to the coils of the vacuum contactor coils to assess proper operating conditions of the coils and to check for coil or sensor faults.

A method of creating a flat-round tube-to-header joint in a CuproBraze™ heat exchanger wherein the flat-round tube-to-header joint is disposed between a tube and a header having a generally circular opening having a first predetermined diameter formed on a first side thereof for receiving one end of a tube, and provides at least one generally circular end having a second predetermined diameter on the tube to fit into the generally circular opening of in the header. The method further provides a predetermined temper on at least one generally circular end which is at least sufficient to enable cold working of at least one generally circular end to prevent premature failures of the flat-round tube-to-header joint. The flat-round tube-to-header joint is formed by inserting one end of the tube into the first side of the header and forming the flat-round tube-to-header joint between one end of the tube and the header.

An automated cooling system and method for energy efficient use with a building structure by adjusting operational parameters is provided. The automated cooling system can adjust operational parameters in response to conditions (e.g., temperature, humidity) detected by sensors located at one or more strategically selected locations inside or outside the building structure. The automated cooling system can ramp speeds of a motor that rotates fan blades in response to changes in the air temperature in the building structure so as to maintain a desired temperature without switching on and off the motor to preserve fan blade inertia.

Disclosed is an anchor rod supporting method applying a deforming energy-absorbing anchor ring for preventing an anchor rod from being broken and ejected, particularly suitable for soft rock large-deformation roadways or sections requiring energy-absorbing yielding supporting. According to the method, the anchor rod (1) penetrates through the anchor ring (2) having opposite holes, and by applying pressure to rock mass (10) by means of a tray (6) and a nut (4), deformation is prevented. When the stress of the anchor rod is increased, the anchor ring deforms in a direction along the opposite holes, and thus the energy-absorbing effect is achieved. The deformation amplitude of the anchor ring can be observed by utilizing fluorescent bands (3) oppositely disposed on the outer sides of the anchor ring, so that the stress of the anchor rod is pre-determined, and a warning effect on sudden breakage of a potential part is achieved. When the deformation of the anchor ring is too large or the fluorescence range is too large, anti-ejection iron wires (11) penetrate through two holes (5) which are formed at the tail portion of the anchor rod in a crossed mode, and are screwed and fixed on an iron wire net (7). If the anchor rod is broken at any key position, the two anti-ejection iron wires which are disposed in the crossed mode can prevent the anchor rod from being ejected into the space of the roadway, and people are prevented from being injured. Also disclosed is an anchor rod supporting apparatus applying a deforming energy-absorbing anchor ring for preventing an anchor rod from being broken and ejected, which is simple in structure, convenient to operate, low in economic costs, safe, reliable and good in effect.
