Abstract: ABSTRACT OF THE DISCLOSURE         A ream collection lift table and associated transfer conveyor system are contained in a unitary assembly which is mounted beneath a sheet discharge end of a sheeting machine.  The lift table portion utilizes a scissors-elevating means for reciprocating a sheet collection surface.  The elevating means includes criss-crossed, collapsible scissors arms, each provided with shaped profile surfaces for engagement with a laterally movable roller driven at constant speed, whereby the collection surface descends at varying rates.  At a lowermost position, the collection surface deposits a collected ream onto a laterally directed belt conveyor, positioned intermediately of the integral assembly.  The belt conveyor deposits the collected ream onto the receiving surface of an orthogonally directed slat conveyor for transferring the ream to a cartoning station off to one side of the sheeting machine. The slat conveyor is formed with slat chain means, the upper portion of which is movable between a lowered, slanted, ream-receiving and an elevated, level, ream-conveying position.  Means for positioning the upper portion of the slat chain includes a reciprocated chain guide member formed underneath with slanted profile surfaces which ride over ramped support walls.

Abstract: CONCRETE LINING OF DRILLED SHAFT               ABSTRACT OF THE DISCLOSURE           In conjunction with the mining of minerals from the earth, it is necessary to construct deep verticle shafts normally between 10 and 20 feet in diameter and typically between 3000 and 6000 feet in depth in the earth.  Technology has been developed for blind drilling of such shafts.  After drilling the shaft however, in order to protect those entering the hole for additional mining operations the shaft needs to be lined with a stack of specially constructed lining segments.          These segments are formed of prestressed concrete.  The concrete segments are lowered one at a time into the bore hole shaft, which is filled with fluid, so as to build up a stack within the hole, thereby lining the hole.  Each concrete segment has a top portion with an approximately V-shaped cross-sectional area with a flat top section and a bottom portion having an asymmetrically cross-sectional shape but such shape partially corresponding to the shape of the top portion so that the segments can be stacked.  As the segments are stacked,an uneven turbulence is created due to the shapes of the top and bottom portions of the segments.  This turbulence helps to flush out any particles from between the concrete segments.  Grout is then placed between the lining segments and the inner wall of the bore hole.  The grouting process is periodically carried out after every few segments have been placed into the hole.    After the lining operation has been completed, the fluid is pumping out of the hole and then the miners can enter the hole for other mining operations.

Abstract: ABSTRACT:             A digital filter in the customary manner com-prises a plurality of delay circuits, a plurality of multipliers and at least one summation device.  The multi-pliers for fixed coefficients may be formed by means of adders and, if a pipeline structure is used, the summation device may also be formed by a plurality of adders.  A result of this, only two different types of circuits are required, namely adders and delay circuits.  In accord-ance with the invention it is proposed to initially integrate a plurality of adders and delay circuits in a regular structure without interconnections and to form the interconnections in a subsequent step after the filter structure has been defined.  Suitably, the individual cir-cuits are designed for one bit only and so-called cells are formed which each comprise a l-bit full adder and a plurality of registers, the cells being arranged in rows and columns.  The connections of the elements within one or more cells are made by means of conductor tracks which all extend in one direction only and which intersect con-necting lines which issue from the circuits.

Abstract: Abstract:     Hot water is an important component in the recovery or extraction of bitumen and heavy oils.  This hot water tends to form emulsions with the oil and when these emulsions are broken by demulsifiers and the oil separates, the remain-ing water retains a black color and cannot be recycled in the process. The black color has been most difficult to remove, but it has now been found that it can quite easily be removed by certain selected adsorbents.  These include high ash coal rejects, fly ash from coking gas and red mud.

Abstract: ACTIVE IMPEDANCE TRANSFORMER ASSISTED LINE FEED          CIRCUIT WITH SUPERVISION FILTERING          Abstract of the Disclosure A supervision filtering function is included in a line circuit wherein tip and ring voltage amplifiers supply energizing current to a two wire communication line via tip and ring primary windings of a transformer and tip and ring feed resistors. The tip and ring amplifiers operate in response to a control circuit which is differentially responsive to resistively coupled voltage signals corresponding to current flows in the tip and ring feed resistors, and which is also differentially responsive to a.c. signals from a secondary winding of the transformer being coupled via a resistive capacitive network to an amplifier in the control circuit.  An output of the amplifier provides a supervisory signal.  A feed switch is operable by a ring signal to conduct ringing currents to the communication line via the tip and ring feed resistors to the exclusion of the tip and ring primary windings.  A control switch is also operated at the same time by the ring signal to open circuit the secondary winding of the transformer such that a resistive capacitive network causes the amplifier to function as a low pass filter to reduce a.c. signal components in the supervisory signal.    - i -
