Abstract: ABSTRACT    Data processing information storage and retrieval system having a memory.  A number of modules are inter-connected with the memory.  Encode and decode modules operate in conjunction with the memory for compacting and expanding data.  A revolve module in association with a delta module and a memory enable coded signals to be transferred into a number of unique but equivalent and related signals.  A seed module enables the shortest of the equivalent signals to be located.  A change module enables any one of the equivalent signals to be updated.          An output module causes an equivalent signal to be converted back to the original signal representation.          Pipe and brightness modules perform a discrimination function on stored information. The data processor includes programs which by unique means and methods structure and retrieve data from the data base.  The retrieval may be based on an inexact match between events and entries of a request and the structured data base.

Abstract: ABSTRACT       In a coke oven coke side door machine, a bottom tray is mounted to collect spillage that results from the removal of coke oven doors as well as the residue buildup that is scraped from the door seals and bottom plugs during the door cleaning operation.  Trays, in the form of inclined planes, are extended from the door machine to catch the coke spillage from the oven and to catch the residue buildup which is scraped from the door jambs during the jamb cleaning operations.  This material gravitates down the trays into the catch pan.  A scraper then pushes the material accumulated in the catch pan to one end of that catch pan where a conveyor carries it to a dump bucket.  The dump bucket can be dumped when the door machine is positioned adjacent a quench car.  All of the above apparatus is mounted onto and within the confines of the door machine.

Abstract: Case 2806 CONTROLLED PULSING OF AIR CLUTCHES   FOR STOPPING A GRINDING MILL               ABSTRACT OF THE DISCLOSURE There is provided a control apparatus for stopping a large grinding mill driven by two synchronous motors coupled to the mill through respective air clutches.  The control includes a clutch actuator control which applies a predetermined amount of pressure of predetermined duration to the clutches sufficient to at least partially close the clutches but insufficient to fully close and lock-up the clutches.  The control apparatus further includes an enable control which periodically enables the clutch actuator control to apply the predetermined amount of pressure.  The enable control enables the clutch actuator control for a predetermined time duration sufficient to stop motion of the mill and synchronous motors.  The present invention provides a system for bringing a mill to a stop relatively quickly without adding significant costs to the mill controls.

The composite structure so provided is then transported to the place of installation of the wall element, at which point it is fastened to the building to form part of its curtain wall.  Once the wall element is fastened to the building, the auxiliary frame is then removed for further use in the preassembly thereon of further wall elements.  In the pre-ferred practice of the invention the posts and tie bars and any other elements desired to form part of the curtain wall of the building are brought to a floor or floors of the building while the building is under construction wherein the preassembly of the wall elements on an auxiliary frame may take place, as and when necessary.  The arrangement facilitates the assembly of the wall elements to form part of the curtain wall in a protected area of the building site which is relatively close to their place of installation.  The movement of the preassembled wall elements is aided, preferably, by the use of trolley means connected to the building.  Apparatus per the invention therefore includes in the first instance a frame to which are assembled posts and tie bars, together with facade panels and glazing, if desired, to form an individual wall element a plurality of which can be joined in the formation of a curtain wall.  The connection between each wall element and the frame on which it is assembled is limited and facil-itates a quick release of the frame from the wall element, once the wall element is attached to form part of a curtain wall.
