Abstract: D-23,210 RESISTIVE PAD by Tom L. Blackburn and Otto G. Wisotzky ABSTRACT OF DISCLOSURE         A resistive pad having an attenuation between input and output terminals (measured with respect to a reference point) that is variable in discrete steps, and having a net resistance between the input and output terminals.  The pad comprises first and second resistive elements, with one of them electrically connected between the input and output terminals and the other of them electrically connected between the reference point and one side of the one resistive element.  Pluralities of control resistors and bi-state switch means are electrically connected together in a prescribed pattern across first and second terminals of the first resistive element, where changing the state of at least a certain one of the switch means produces a step change in the net resistance measured across the first resistive element, which requires that changing the states of individual switch means produce different prescribed step changes in the decibel value of attenuation that are cumulative.

Abstract: TITLE            INTERCONNECTING SYSTEM FOR MARINE FLOATS      ABSTRACT OF THE DISCLOSURE         A fastening system for interconnecting a row of marine floats while allowing relative movement of the floats resulting from wave action.  One or more chains, cables or other securing lines extend through the floats from one end of the row to the other.  The securing lines pass through reces-ses formed in adjacent end walls of the floats.  A resilient member having a central bore is inserted into the recesses with the securing line passing through the bore.  The resili-ent member absorbs longitudinal forces imparted to the floats.          It also restricts transverse vertical and horizontal movement of the floats with respect to each other while allowing pivot-al movement of the floats.  A metal tube preferably lines the bore to prevent the securing line from abrading the resilient member and to increase the shear strength of the resilient member.  The recesses may also be lined with a frame, and the frames of two or more recesses in a given end wall may be in-terconnected for additional strength.  The ends of the secur-ing lines may be fastened to respective floats at the ends of the row, and one of the ends may be connected to a weight hanging from a float to tension the securing line.  The floats and resilient members loosely surround the securing line so that individual resilient members and the securing line can be easily replaced at any time.

Abstract: 154,456 CAN/JLG (Fleming et al.) ABSTRACT    Penetrations or passageways through fire resistant walls, floors, partitions and ceilings are frequently necessary to provide for present or future pipes, cables or conduits.  A device fixed to the walls of the penetration provides a barrier to prevent the passing of fire, heat, smoke and toxic gases, and water through the penetration under adverse conditions of fire or elevated temperatures. The device includes at least one end cap capable of providing a cold smoke seal.  An intumescent material which in the event of excessive heat or fire, foams and expands to substantially fill the penetration, is provided.  The device may include a laminated restraining layer to provide assurance that the char formed during the intumescent reaction to fire and heat, is generated so that the penetration cavity is optimally filled.

Abstract: ROGERS, BERESKIN & PARR     INVENTION: MOORING DEVICE             INVENTORS:   DEREX FOSTER               COLLIN RICH     ABSTRACT OF THE DISCLOSURE     A  mooring device is secured to a sea-going vessel to handle anchor line of the type consisting of an upper length of wire rope in series with a lower length of chain cable.          The mooring device comprises a traction winch for handling the wire rope and a windlass for handling the chain cable.          The windlass includes a chain wheel so positioned beneath the winch when the mooring device is located in its operative position that the anchor line can be hauled by the winch substantially vertically between flanges of the chain wheel.          In operation the wire rope can be hauled up or paid out with-out actively engaging the chain wheel, the flanges merely serving as a guide to ensure that the anchor line is properly located for chain handling functions.  When a portion of anchor line comprising the junction between the wire-rope and chain cable is drawn above the chain wheel, a chain holder can be engaged to take up the tension in the chain cable, and a hydraulic anchor line retractor is then activated to draw the anchor line portion generally horizontally from its vertical position to a retracted position in which links of chain are draped over link-gripping whelps of the chain wheel.  The chain hanger can then withdraw, after the windlass is activated to haul the chain cable upwardly.     A conventional static and dynamic brake system is provided to regulate the paying out of anchor line during a substantially reverse process.

Abstract: Abstract of the Disclosure A method of controllably varying the dimensions of cavitated objects such as hollow spherical shells wherein a precursor shell is heated to a temperature above the shell softening temperature in an ambient atmosphere wherein the ratio of gases which are permeable through the shell wall at that temperature to gases which are imper-meable through the shell wall is substantially greater than the corresponding ratio for gases contained within the precursor shell.  As the shell expands, the partial pressures of permeable gases internally and externally of the shell approach and achieve equilibrium, so that the final shell size depends solely upon the difference in impermeable  gas partial pressures and shell surface tension.

Abstract: FLUIDIZED BED HEAT EXCHANGER WITH CONTROL     TO RESPOND TO CHANGES IN DEMAND                              Abstract In a fluidized boiler system, the rate of fuel flow and bed depth are simultaneously controlled in response to variations in a load demand signal representing the need for steam output from the system.  When the load demand changes, the rate of fuel flow is varied accordingly to provide a change in the bed temperature to thus provide a rapid response to the change in the demand signal.  At the same time, the system changes the rate of flow of limestone to the bed and the rate of removal of spent particulate material of the bed to change the bed depth to respond more slowly to the change in the demand signal.  As the depth of the fluidized bed approaches a value corresponding to the demand signal, the temperature of the bed will change back toward a median value.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus is provided for separating, counting and stacking sheets, including a feed roller and cooperating stripper shoe for permit-ting the passage of only single sheets fed therebetween.  The sheets are moved along a curved path defined by a guide plate cooperating with the feed roll as the sheet emerges from the region between the stripper shoe and feed roll.  The leading edge of the sheet moving along the curved path enters into a nip between an acceleration roller and an acceleration idler mounted on a common axis with the feed roll abruptly to accelerate the sheet and to drive it into a stacker wheel which delivers the sheet to an outfeed stacker.  The feed roll is provided with a plurality of surfaces of differing coefficients of sliding friction to facilitate separation of sheets.  Thus this apparatus is useful for accurately counting paper currency for both counting and batching purposes particularly when the paper currency has been in circulation for quite a while and/or has been roughly treated, mistreated, or even mutilated.
