Patent CA-2108909-A1 (CA)
Inventor: WOLF WILLIAM E
IPC: G01N21/85
Filed: 1992-04-29
Abstract: An apparatus for optically detecting light-absorbing contami-nation in at least one particle of low optical-loss material comprises an optical integrating chamber for containing the particles. A laser for emitting a laser beam to illuminate the particles is mounted in the plane of rotation of a rotating mir-ror such that the laser beam scans in a fan scan. A scanning assembly is mounted in optical alignment with the laser for reflecting the la-ser beam and for causing the laser beam to scan the particles in the optical integrating chamber. A fo-cusing assembly is mounted in opti-cal alignment with the laser For fo-cusing the scanning laser beam on-to the particles in the chamber, the focusing assembly operating in conjunction with the scanning as-sembly so that light from the laser beam is reflected from the particles and is repeatedly scattered onto the interior walls of the integrating chamber. A light sensing assembly is mounted on the integrating chamber for receiving the repeatedly scattered light from the interior walls of the integrating chamber and for generating a signal indicative of the intensity of the repeatedly scattered light. A decrease in the intensity of the repeatedly scattered light is a function of the presence of light-absorbing contamination in the material.

Title: Fiber-optic amplifier with a facility for monitoring the pump power and input power
Inventor: BUELOW HENNING
IPC: H04B10/00
Filed: 1994-06-21
Abstract: Abstract Fiber-Optic Amplifier with a Facility for Monitoring the Pump Power and Input Power In fiber-optic amplifiers, various parameters, such as the input power, are measured to obtain information on the operating condition of the transmission link and of the fiber-optic amplifier itself. In prior art fiber-optic  amplifiers,  a portion of  the  input power is coupled out for this purpose by means of a coupler (2). If low-power optical signals such as digital signals are transmitted, the coupled-out portion of the input power can only be detected with complicated and costly cir-cuitry.            In the novel fiber-optic amplifier, the pump power and inputs power are monitored by coupling out and evaluat-ing the radiation resulting from  amplified spontaneous emission (ASE). This provides information on the state of the input signal.            (Fig. 1)

Abstract: Different people have different tastes for different types of bread: some like white, some like brown; some like thick sliced, some like thin sliced, etcetera, etcetera. To satisfy this kind of different tastes in different members of a family, one often has to buy different kinds of bread. This often results in there being too much bread to be consumed in good time and, hence, lot of wastes of bread. Buying in smaller packages is generally uneconomical since the prices of smaller packages are almost invariably relatively higher.          The present invention may help avoid these kinds of difficulties.

Abstract: A method for making strips of a composite elastomeric membrane  for application as a roof covering  in a continuous process,  wherein  individual  lengths  of the uncured composite membrane are joined together by a stepped bevelled lap joint.  Two continuous plies of uncured elastomeric material are formed by calender rolls with the longitudinal edges being skived prior to the plies leaving the calendering rolls.   The two plies are laminated together in a slightly offset relationship to form a length of composite membrane having stepped bevelled longitudinal edges.   Predetermined lengths of the membrane are cut from a generally continuous length of composite membrane, and successive trailing and leading longitudinal edges of said cut lengths are slightly overlapped to form a predetermined length composite sheet having stepped bevelled lap joints.  The composite sheet is then vulcanized and then may be subsequently cut transversely to the lap joints to form individual strips of the composite sheet.
