Title: Method and apparatus for processing contaminated soil
Inventor: KREFT WILFRIED
IPC: B09B5/00
Filed: 1989-10-26
Abstract: ABSTRACT          What is proposed is a method and an apparatus for reprocessing contaminated soil and like materials by stripping, decontaminating and refilling the stripped area with cleaned soil.  The stripped soil is dried and crushed in a mill through which hot gases flow, the resulting mixture of solids and gas being passed to a cyclone separator where it is separated into its gaseous and solid constituents.  The solids are treated at an elevated temperature, this being where an initial decontamination takes place.  Following a further separation of the solid and gaseous phases in an additional cyclone the solids, which are at least still partly contaminated, are introduced into a holding zone in the form of a through area where they are treated at temperatures corresponding substantially to the decontaminating temperature.  The waste gases from the mill and decontaminating unit are subject to thermal after burning, and for reasons related to power engineering, are used again, at least in part, in the decontaminating process.

Patent CA-2019165-A1 (CA)
Inventor: YOSHIHARA KENZO
IPC: G07D7/20
Filed: 1990-06-18
Abstract: An apparatus and method for validating a paper-like piece  are of a type having a detector which  irradiates light  onto  a  deposited paper-like piece  and  thereby produces  a detection signal corresponding to a  pattern on  the paper-like piece and validating  the  paper-like piece  by collating the detection signal produced by the detector  in  response to deposition of  the  paper-like piece with a predetermined standard  pattern.   Features of  the apparatus and method are that a reference paper-like piece having no particular pattern is deposited and reference  level  data  is obtained on the  basis  of  a detection signal produced by the detector in response to this deposition, that data to be examined is provided by converting  a detection signal produced by the  detector in  response to deposition of a paper-like piece  to  be validated  to a ratio to or deviation from the reference level data and that validation is made by collating this data  to be examined with the standard  pattern.   Since the base for normalizing measured data for collation  is set  at  the  level of the reference  paper-like  piece, validation becomes less vulnerable to adverse effects by a parts error and an assembling error in an optical type detector  with resulting improvement in  the  validation accuracy.

Title: Atm transmission system with a variable transmission rate
Inventor: KASAHARA HIROYUKI
IPC: H04L47/43
Filed: 1991-03-18
Abstract: A cell including a time stamp, first cell sending rate, first requested cell sending rate is transmitted from a transmitting side to a receiving side.  At the receiving side a second cell sending rate is determined based on the first reqeusted cell sending rate, and a second requested sending rate is determined based on the first cell sending rate and the cell discard information.   The second requested cell sending rate is transmitted from the receiving side to the transmitting side to determine the first cell sending rate based on the cell discard information detected at the receiving side.          Therefore, the cell sending rate is determined in accordance with a frequency of the discard of the cells so that the cell sending rate is decreased when the cell discard occurs and the cell sending rate is increased when the cell discard does occur.

Title: Hardened insert and brake shoe for backstopping clutch
Inventor: OSTRANDER ROBERT J
IPC: C23C16/34
Filed: 1991-04-26
Abstract: An improved hardened insert and brake shoe adapted for use in bi-directional backstopping clutches is disclosed.      The inserts are formed from a base material of high speed alloy tool steel, which is relatively inexpensive and easy to machine. The base material is formed into the desired shape for the insert, then hardened and tempered by conventional processes to achieve a desired hardness.      Then, a coating of titanium nitride is applied to the insert by a physical vapor deposition process or a chemical vapor deposition process. The titanium nitride coating provides a very hard surface to the insert, which permits the insert to be used in the backstopping clutch. In an alternative embodiment, the brake shoes are formed in the manner described above, and no inserts are used in the clutch.
