Title: Elevator system with independent limiting of a speed pattern in terminal zones
Inventor: SCHAUDER COLIN DAVID
IPC: B66B5/10
Filed: 1990-01-31
Granted: 1999-05-11
Abstract: A feedback  controlled elevator system driven by a traction drive motor  in  response  to  a  speed pattern provided  by  a  car  controller.    The  speed pattern is limited when the car approaches a terminal floor  within a predetermined  terminal  slowdown  zone  adjacent  to the terminal floor.  A pattern limiting signal is  provided in response to digital integration  of shaft encoder signals which provides a digital position "x" of the  car within a terminal zone.   The  position "x" of the car is then used to access a read-only-memory  which  contains  the  maximum car speed  for the  specific location of the  elevator car. The value from the read-only memory is used to limit the speed pattern.

Title: Fluidized bed combustion apparatus for generating environmentally-innocent ash
Inventor: WILLIAMS ROBERT M
IPC: B09B3/00
Filed: 1990-02-14
Granted: 1995-05-09
Abstract: A method for disposing by incineration of waste material containing sludge and garbage of various kinds which when combined results in a composite waste material prepared by performing multiple steps in its handling wherein the composite material is first sub-jected to a grinding step for thorough intermixing of the sludge that may contain a high percentage of mois-ture with garbage that can contain very little moisture. After grinding, the composite waste material is pro-cessed in a cyclone where the gases that are used to transport the ground matter can be separated while the solids are subjected to classification by the use of a vibratory screen where the paper, fluffy waste, and similar materials can be separated from the smaller and harder particulate components.  The separated components are subjected to individual impact grinding steps prior to being recombined in the combustor where incineration takes place.  The gases separated in the cyclone separator are reapplied to the grinding steps for moving such material into the incinerating combus-tor, and any excess gases are delivered to the incin-erator, along with ambient air for establishing suf-ficient oxygen to support combustion in the furnace at a temperature that will sanitize and destroy odors during the incineration of the waste material and after the sanitizing step in the incinerator, the gases are exhausted through suitable heat exchanges and filtering medium.

Abstract: Improvements  in  the  art  of  sensor  and  display technology  now make  the  implementation  of  a  workpad concept feasible.   While prior art touch displays are acceptable for short, casual use tasks, they may not be feasible  or  suited  for  intensive  use  tasks.    Recent improvements  in  the  optical  qualities  (brightness, contrast, viewing cone) of flat panel displays, such as LCDs,  allow implementing a touch screen for use in a horizontal orientation.  This greatly improves the human factors for applications involving extensive pointing, drawing or writing.
Patent CA-2016938-C (CA)
Title: Ribbon print track reinking with a roll system
Inventor: PATERRA JEFFREY HOWARD
IPC: B41J32/02
Filed: 1990-05-16
Granted: 1996-01-23
Abstract: The specification teaches an apparatus for selectively reinking an endless ribbon in that portion of the ribbon known as the ribbon print track.  The ribbon print track is created in an endless ribbon by the repeated striking of the ribbon by a print mechanism thereby deforming the ribbon and depleting it of ink.  Reinking the entire ribbon uses more ink than is necessary.  Reinking only the print track extends the life of the ribbon by selectively using the available supply of ink. The apparatus described herein achieves this result by use of an ink reservoir which supplies ink to a drive roller, which through a rotating pinching movement in cooperation with another roller, advances a ribbon into a stuffing cavity of an ink cartridge.  The ink reservoir is rotatably mounted and formed to apply ink only to that portion of the drive roller which corresponds to the print track of the ribbon.  The drive roller may be a composite of more than one roller in a stack of rollers and a single roller in the stack of rollers may receive the ink from the ink reservoir and transfer it to the ribbon print track.

Title: Baseband signal processing circuit for a radio communication apparatus
Inventor: IWAHASHI KOJI
IPC: H03G11/00
Filed: 1991-12-27
Granted: 1996-11-26
Abstract: A baseband signal processing circuit for a radio communication apparatus has an amplifier for amplifying the amplitude of an input baseband signal, a limiter for limiting the amplitude of the amplified baseband signal, an amplitude detector for detecting the amplitude of the output signal of the amplifier, and a control unit for controlling the gain of the amplifier in response to the output of the amplitude detector. When the amplitude detector detects an amplitude greater than predetermined one, the control unit controls the gain of the amplifier in such a manner as to maintain the output of the amplifier at a constant level. As a result, the output level of the amplifier is prevented from exceeding the limiter level of the limiter. This allows the maximum frequency transition to be set up with no regard to frequency and suppresses distortions regarding signals exceeding the standard frequency transition.

Title: Protective cover for pipe end
Inventor: TEMPEL LORNE F
IPC: F16L57/00
Filed: 1993-01-13
Granted: 1997-10-21
Abstract: A weather protector for the end of a pipe section, e.g. for use in a pipeline, tends to prevent the ingress of snow and rain into the interior of the pipe.  The weather protector is made from a generally circular blank having peripheral tabs, a few  of  which  are  widely  circumferentially  spaced  and  are appreciably longer than the remaining tabs and extend over the edge of the pipe end.  The weather protector is placed in the interior of the pipe, the tabs forming a substantially continuous cylindrical rim portion that engages the interior cylindrical surface of the pipe.   The longer tabs position the weather protector in the interior of the pipe by overlapping the pipe end to prevent the weather protector from being pushed further into the interior of the pipe. The spacing between any neighbouring pair of longer tabs is sufficient that a pipe gripping element may grip the edge of the pipe without encountering any of the tabs so that the weather protector may stay in place at the pipe end even though it has been handled repeatedly.  The outermost circular surface of the weather protector is preferably water repellant.  A small hole may be provided in the circular area to relieve pressure differentials between the interior and the exterior of the pipe.   The exterior tab ends are preferably tapered  to reduce wind drag  during  transit.    The weather protector is preferably made of cardboard or similar disposable biodegradable material.
