Abstract: There is provided apparatus for converting between a medium tenacity yarn producing machine and a high tenacity yarn producing machine. The apparatus comprises a pulley (40) adapted to be driven by a motor after removal of a multi-disc texturing unit (11) of the medium tenacity yarn producing machine from a casing (14). A bracket (30) is securable to the casing (14) with the pulley (40) mounted to the bracket (30) by means of a bearing unit (46) such that the pulley (40) is rotatable relative to the bracket (30). The bracket (30) has one or more mounting points to which a pin spindle texturing unit (20) of the high tenacity yarn producing machine can be attached. An endless drive belt (50) connects the pulley to a drive shaft (24) of the pin spindle texturing unit (20). The diameter of the pulley (40) is greater than the diameter of the drive shaft (24), and the diameter of a drive disc (23) of the pin spindle texturing unit (20) s larger than the diameter of a disc pin spindle (21) of the unit (20).

Abstract: A large-bore (at least 180 mm diameter) diesel engine cylinder configuration featuring a piston crown bowl having an acute re-entrant angle and, optionally, an anti-polish ring. The acute re-entrant angle crown bowl involves a maximum radius of the crown bowl exceeding a minimum crown bowl radius, wherein the maximum crown bowl radius is located farther from the squish face than is the minimum crown bowl radius. The acute re-entrant angle crown bowl applied to large-bore, medium-speed diesel engines yields an improvement in performance and emissions characteristics. The anti-polish ring may be integrally formed with the cylinder liner and used in any internal combustion engine.

Abstract: A covering and mounting structure for mounting a motion detector having electronic adjustment controls, light emitting diodes (LEDs), and at least one motion detector lens, provides for selectively covering the controls, LEDs and a motion detector lens. The structure can be cylindrical or non-cylindrical in shape, and disposed in pendant or standing-post arrangement. Furthermore, the structure includes a telescopic structure or an exterior cover for the selective covering. In one embodiment, the structure includes one downwardly viewing first motion detector lens and a laterally viewing second PIR motion detector lens.

Abstract: A damper interlock mechanism comprising a housing including first and second apertures, a damper assembly pivotably mounted in the first aperture and a swing out unit pivotably mounted in the second aperture for pivotal movement between a first shipping position and a second operational position. The mechanism also includes an actuator for actuating the damper, and a damper control rod having a first end operationally connected to the actuator, a second end operationally connected to the damper assembly, and an intermediate portion. The intermediate portion includes means for interlocking the damper control rod with the swing out unit when the swing out unit is in the shipping position.

Abstract: A tube arrangement for a tube-type heat exchanger. The tube arrangement provides for the location of the tubes in the upper portion of the drum defining the combustion chamber of the heat exchanger. In one embodiment, four heat exchange tubes are provided, with two of the tubes disposed such that the axial center line of the tube lies across the horizontal center line of the heat exchanger drum, and with two tubes disposed entirely above the horizontal center line of the drum.

Abstract: A premix furnace burner for a gas combusting furnace. The furnace burner includes a premix chamber and a burner plate assembly. The burner plate assembly is comprised of a burner plate with a plurality of relatively small apertures for the passage of a mixture of combustible gas and air and an annular ring for retaining the burner plate. The annular retaining ring determines the capacity of the furnace burner by appropriately sizing of the opening in the annulus of the retaining ring to sealingly overlay a selected portion of the burner plate apertures. The retaining ring further secures the burner plate in the correct operational position while simultaneously permitting the burner plate to expand and contract in response to temperature changes induced by combustion of the gas and air mixture.
