Inventor: IFILL LEE
IPC: C02F1/32
Filed: 1991-07-15
Abstract: A UV lamp rack assembly usable in an ultraviolet ray wastewater treatment system, the rack including a horizontal hanger bar. When the assembly is installed in a channel through which a stream of wastewater to be treated is conducted, the bar is then supported above the channel in the flow direction of the stream. Depending from the bar at an upstream position is a vertical rod along which sleeves are pivotally mounted at spaced points thereon whereby each sleeve can be swiveled in a horizontal plane. Depending from the bar at a downstream position is a vertical conduit along which detachable lamp couplers are mounted at corresponding points, each coupler housing a lamp socket that is connected through the conduit to a power source. Extending between each sleeve and the coupler corresponding thereto is a lamp unit formed by a transparent protective tube enclosed at its upstream enc and housing an elongated UV lamp whose terminal pins are at the downstream end. The upstream end of the unit is slidably received in the rear section of the sleeve, while the downstream end of the unit is securely received in the coupler, the terminal pins of the lamp then being plugged into the socket to render the lamp operative.      To remove a particular lamp unit from the rack, it is swiveled to an angular position.

Patent CA-2051527-A1 (CA)
Title: Fiber identifier
Inventor: COX LARRY R
IPC: H04B10/075
Filed: 1991-09-17
Abstract: Abstract of the Disclosure A fiber identifer for detecting the presence or absence of an active data signal or a test signal in an optical fiber.  The instrument includes a piston which positions a portion of the fiber under test against an optical detector, the piston being located within a housing, and the housing being attached to a drive rod. The rod is responsive to a levered actuation mechanism, but a damper controls the movement rate of the rod, and hence the piston, to slowly bend the fiber, minimizing disruption of any signal flowing through the fiber and preventing undue mechanical stress which could damage the fiber.  A precision spring within the housing is used to limit the pressure applied by the piston against the optical fiber.  The housing also includes a novel arrangement of electrical contacts to sense the position of the piston and, indirectly, the position of the rod.

Abstract: Apparatus for installing a liner in a pipe by reducing the diameter of an elongated tube of lining material, to allow it to be positioned within the pipe, heating the tube of lining material to soften it, and expanding the tube of lining material within the pipe to form a liner, includes a plurality of disk-shaped expanders for engaging the tube of lining material from the inside, and expanding the lining material to form a liner, an elongated body member for holding the disk-shaped expander in a spaced apart at least generally parallel orientation, and bypass means for conducting a heated fluid past the disk-shaped expanders from a first end of the apparatus to a second end.  A method for installing a pipe liner in a pipe includes the steps of reducing the diameter of the liner, so that it can be positioned within the pipe, installing the liner in the pipe, enlarging an upstread end of the liner, disposing a liner expander within the upstream end of the liner, pressurizing the upstream end of the liner with a heated fluid, the temperature of the heated fluid being sufficient to soften the liner, and the pressure of the heated fluid being sufficient to propel the liner expander from the upstream end of the liner to a downstream end, providing means associated with the liner expander for allowing a portion of the heated fluid to bypass the liner expander for heating and softening the liner ahead of the expander, as the expander is propelled by steam pressure from the upstream end of the liner to the downstream end of the liner, while maintaining a propelling pressure upstream of the expander, retaining the expander at least partially within the liner at the downstream end, for pressuring substantially the entire length of the liner, and reducing the temperature of the pressurizing fluid to cool the liner below the softening temperature, to allow it to stiffen and form a liner within the pipe.

Abstract: In a burner for operating an internal combustion engine, a combustion chamber of a gas turbine or firing equipment, which consists essentially of at least two hollow conical partial bodies (1, 2) positioned one upon the other in the flow direction, the ignition of the air/fuel mixture forming in the hollow conical space (14) takes place by means of ignition electrodes (24a, 24b, 25a, 25b) which are placed at a location where there is a low flow velocity of the combustion air (15). This achieves the effect that the flame tongues starting from the electrode ends (25a, 25b) of the ignition electrodes (24a, 24b) can feed a flame front (7) forming at the outlet from the burner continuously and along ordered paths, i.e. paths directed in the flow direction with slight swirl in consequence of the motion of the combustion air (15), so that a stable reverse flow zone (6) forms.

Abstract: A process and a device are used to separate or slit a rigid material (30), especially wood, with a modulus of elasticity of preferably approximately 50,000 to 400,000 kg/cm. A narrow tool having chip-removing elements (16), especially a circular saw blade (15), produces a kerf (36) of finite width in the material (30) at a cutting speed of more than approximately 40 m/s. After the chip-removing elements (16) have passed, a separator element (20) bends a side piece (33) out of the kerf plane (3-7) so that after the chip-removing elements (16) have passed, the side piece (33) is always at a distance from the tool. When viewed along the feed direction (31) of the material (30), the separator element (20) is provided, at a distance from its periphery (22), which is contiguous to the tool and is first to come into contact with the material (30) when the material (30) is fed in, with a hump (25). An imaginary connecting line (35a) runs between the hump (25) and the chip-removing elements (16) at a distance (40) above a first section (23) of the separator element (20) lying between hump (25) and periphery (22). (Figure 3).
