Patent CA-2030964-A1 (CA)
IPC: H04N1/32
Filed: 1990-11-27
Abstract: A facsimile device includes an automatic receiving function, in which, after the facsimile device is connected to a line, users can store a match pattern suitable for the connected line.  At the stage of production of this facsimile device, no match pattern for an automatic receive mode is stored in this facsimile device, or alternatively, several match patterns corresponding to ringing signals employed in several countries are stored independent of destinations of the facsimile device.  This facsimile device includes a characteristic setting mode.  In this characteristic setting mode, this facsimile device detects a ringing signal from the line connected thereto and determines characteristic values of the detected ringing signal.  The facsimile device sets the determined characteristic values in a match pattern employed in practice for determining whether or not there is a ring to call the facsimile device in the automatic receive mode.          Thus, even if installed in any of a plurality of countries, or connected to a PBX that outputs an extraordinary ringing signal, this facsimile device can perform the automatic receiving function.

Title: Safety interlock system for fastener driving tool
Inventor: MEYER ROBERT J
IPC: B25C1/04
Filed: 1991-05-14
Abstract: Abstract of the Disclosure A fastener driving tool having a power mecha-nism operable during a fastener driving stroke to drive a fastener into a workpiece when an operator depresses a manually operable trigger and a safety member is in an actuated position.  A safety mechanism for the fastener driving tool includes an interlock mechanism associated with the trigger and the safety member that assures that (1) the trigger will not be depressed from its standby position to its actuated position unless the safety mem-ber is moved to its actuated position; (2) the safety member will be locked into its standby position if the trigger is depressed prior to the safety member being depressed against the workpiece; (3) the trigger will be permitted to return toward its standby position even though the safety member is not fully engaged against the workpiece so that the fastener driving tool is reset to a static condition; (4) the trigger is permitted to return to its rest position only when the safety member is in its actuating position; and (5) the safety member will be prevented from returning from its actuated position to its standby position while the trigger is still in its firing position.  In order to accomplish these safety interlock functions, the trigger has a trigger rod and the safety member has a series of reliefs into which the trigger rod may become lodged depending on the relative positions of the trigger and the safety member.

Title: Process for waste injection into landfill
Inventor: CHESNER WARREN
IPC: B09B1/00
Filed: 1991-08-19
Abstract: The present invention relating to a process for managing wastes and reclaiming landfill sites by using the inherent void space that exists within municipal solid waste landfills is disclosed. The process comprises the injection of selected wastes and additives under pressure into the void space of existing landfills.  Various materials can be added to the selected waste from such as hydraulic cement, lime, coal fly ash, waste fixing agents, buffering agents, water and plasticizers. These additives can assist in adding strength to the waste form, creating an insoluble waste material, adjusing the pH environment of the injected material, and enhancing its flowability. Depending on the waste type and additives, the process can be used to encapsulate wastes already existing within the landfill, reduce the permeability of the landfill, fix waste contaminants within the landfill to prevent them from leaching, increase the bearing capacity of the landfill, and reduce the ultimate settlement of the landfill. The process can also be used to increase the rate of consolidation and reduce the height of the landfill, or if appropriate organic sludges are added, the process can be used to enhance the rate of biodegradation of organic materials within the landfill, and to increase the rate of landfill gas production and methane gas recovery.
