Title: Testing apparatus for an item in sheet form
Inventor: BERCOVITZ CHRISTIAN
IPC: G07D7/20
Filed: 1990-04-25
Abstract: ABSTRACT        TESTING APPARATUS FOR AN ITEM IN SHEET FORM       For automatic recognition of the authenticity of items in sheet form such as bank notes, for example in an automatic service machine, the  transparency  of each  bank  note  is  examined  in  predetermined spectral ranges.  The measuring system is arranged between units of a transport system and, in a passage opening formed from a collector and a  diffuser,  produces a  narrow  read-out  light  beam which  extends transversely over a scanning plane.  The bank note is conveyed through the read-out light beam, and the light which shines through the bank note in the read-out area is collected in the collector and passed to a  photosensitive  detector.    An  evaluation device  forms  a  single measurement value in respect of transparency in the spectral range for each of the successively scanned read-out areas, and compares the measurement values of the bank note being tested with pattern signals stored in a memory of the evaluation device.

Patent CA-2028915-A1 (CA)
IPC: F23G5/16
Filed: 1990-10-30
Abstract: An air-starved, batch burn, modular, municipal waste incinerator is designed to oxidize unsorted loads of heterogeneous materials in quantities ranging from 5 to 500 tons per 12 to 15 hours. The system is designed such that through air mixing, air turbulence, and temperature control, it is possible to burn this material with a highly favorable stack emission product, without the need for bag houses, dry scrubbing, or other elaborate down stream air processing equipment. The incinerator includes a primary combustion chamber (12) connected to a secondary combustion unit (14) by a gas transfer tube (16,50). Solid material in the primary (12) is oxidized - or gasified - without live flame. Flammable gas is vented into the secondary (14) for ignition. Combustion gases from the primary chamber are completely burned in the secondary combustion unit (14) as the gases pass upwardly through an air mixing ring (66) and tangentially disposed re-ignition burners (70). The tangential orientation of the re-ignition burners (70) creates a vortex through which the combustion gases travel before exiting from the stack.

Abstract: ABSTRACT   A process for the fabrication of composite products from sugar cane bagasse and minor amounts of adhesive binder has been described. Steam exploded bagasse fibers, after extraction of sugar, were blended with polyethylene (low, medium and high density) and an adhesive binder (polyisocyanate) in a roll mill and compression molded at 180-210°C, at a pressure of 18.6 MPa, for 10 minutes to obtain a composite. Composites of bagasse treated with the polyisocyanate produced superior mechanical properties than the untreated bagasse composites. These composites also showed lower water absorption and better dimensional stability.

Inventor: CRAMPTON DAVID L
IPC: H03G3/00
Filed: 1991-06-21
Abstract: RF power is sampled and measured at the input and output of a solid state pow-er amplifier using directional couplers and matched square law detectors. Outputs from the detectors are applied to differential inputs of a DC operational amplifier. Outputs from the detectors are compared and filtered in the operational amplifier and the result-ing difference signal is applied to a control input on a switching type power supply. The power supply converts a DC input voltage to the various positive and negative vol-tages required to operate the RF devices in the solid state power amplifier. When the control loop is closed, the supply voltage varies to maintain a constant operating point resulting in constant gain, efficiency, and linearity for the overall solid state power am-plifier despite variations in signal levels and signal composition. In another embodi-ment, the solid state power amplifier has a series of single-ended low power amplifiers terminating in an output high power module. In the output module, one medium power device acts as a driver stage for four high power devices connected in parallel. The out-put stages are hybrid coupled, and isolators before and after these hybrid coupled out-put stages isolate the driver from the final amplifiers and protect the output devices from reflected signals. A dynamically controlled PIN diode variable attenuator at the amplifi-er input allows the operating point of the amplifier to be selected and adjusted while the closed loop function is in operation. A hybrid matrix power amplifier system is also disclosed.
