Abstract: ABSTRACT OF DISCLOSURE     A molded insulating insert of expanded polystyrene has a central section and hingedly connected side sections which are bendable toward each other to bring the insert to a U-shaped configuration for insertion in a building block cavity.  The hinges are formed to provide resistance to full ninety degree bending of the side sections so that the insert side sections are inclined slightly outwardly in a free condition.  On flexing in-wardly and insertion in a block cavity the side sections tend to spring outwardly and frictionally grip the walls of the cavity.          Lug-notch connection means frictionally retain the inserts in the U-shaped configuration and prevent dislodgement of sections in the event of hinge rupture.  In molding the inserts, a transfer process is employed with the hinges partially formed in a hot mold and thereafter fully formed in a cold mold.  The polystyrene is compressed in the hinge area to a higher density for hinge in-tegrity.  Density in the hinge area is approximately doubled.          Reflective foil is also applied to the inner surfaces of the side sections.

Abstract: ABSTRACT       Weight bearing in the face of constant unchanging lumber lordosis or kyphosis contributes to low back pain.  Solid low back inserts encourage constant facet loading by accentuating lumber lordosis. Absence of any back support forces constant disc loading.  Back pain induced by mechanical trauma of prolonged sitting can be pre-vented or eased by unweighting the offending lumber disc(s) or facet joints.  In this invention,a torso gripping girdle is hung against the anterior face of any given seat back by weight bearing belts. These belts anchor on posterior face of the seat back.  The subject wearing the torso gripping girdle is suspended in a sitting position approximately 1 centimeter above the seat bench.       Inserted below the person is an air filled thick walled cushion that is inflated periodically by an air pump that is activated by a pro-grammable automatic recycling timer, thereby raising the subject, re-ducing tension on the supporting straps and loosening the cinching laced mechanism on the girdle so that its grip on the abdomen and thoracic cage is reduced.  Deflation of the seat cushion through a controlled bleeding valve reapplies pull on supporting starps, thereby squeezing and suspending abdomen and thorax and unweights the lower disc joints at levels lumbar[5] and sacral[1] and probably also lumber [3] and [4].       The girdle is lined by another posterionly placed air filled inflatable Inserted below the person is an air filled thick walled cushion that is inflated periodically by air pump that is activated by a pro-grammable automatic recycling timer, thereby raising the subject, re-ducing tension on the supporting straps and loosening the cinching laced mechanism on the girdle so that its grip on the abdomen and thoracic cage is reduced.  Deflation of the seat cushion through a controlled bleeding abdomen and thorax and unweights the lower squeezing and suspending abdomen and thorax and unweights the lower disc joints at levels lumber [5] and sacral [1] and probably also and [4].       The girdle is lined by another posteriorly placed air filled inflatable and deflatable cushion whose purpose is to facilitate and augment grasping of varying body trunk diameters comfortable.  Inflation and deflation of this cushion is also mediated by a programmable auto-matic recycling timed air pump.       During inflation this posteriorly placed girdle bladder forces passive accentuation of lumber lordosis which manoeuvre helps lessen constant facet loading.       In summary this invention eases back pain induced by prolonged sitting by periodically unweighting low back support mechanisms and also by passively varying low back posture thereby cyclically loading and un-loading disc and facet lumbar joints.

Abstract: ABSTRACT OF THE DISCLOSURE         A one shot firing circuit for electrically powered tools is described which includes a manually operable normally open trigger switch connected electrically in series wth a solenoid coil and an AC power source for controlling the supply of electrical power to both the firing circuit and the solenoid, such that when the trigger switch is open, the path of current flow to the solenoid coil is physically interrupted.  The firing circuit also includes an SCR connected electrically in series with the trigger switch, the solenoid coil and the AC power source, for controlling the flow of current through the solenoid coil after the trigger switch has been closed.  The firing circuit further includes a timing circuit connected to the gate of the SCR which is operable in response to the closing of the trigger switch to provide a predeterminable delay after the trigger switch is closed before enabling the SCR to conduct and permit a unidirectional current impulse to flow through the solenoid coil of sufficient magnitude to energize the solenoid. The timing circuit also operates to disable further unidirectional current impulses through the solenoid coil once the solenoid has been energized until a predeterminable delay after the trigger switch has opened.

Abstract: MICROPROCESSOR CONTROLLED CARDIAC PACEMAKER           WITH VENTRICULAR RATE LIMIT                      ABSTRACT         A microprocessor-controlled pacemaker is pro-grammed to extend an atrial refractory interval in re-sponse to the detection of events which could initiate a pacer sustained tachycardia.  The extended atrial refractory interval ensures that a spurious atrial event resulting from retrograde conduction of a ventricle event will not cause a pace of the ventricle.  The pacer is also programmed to break out of a pacer sustained tachycardia by inhibiting a ventricular pace when a predefined number of previous successive ventricular paces have occurred at the ventricular rate limit.  The pacer is further programmed so that in response to a high atrial rate, the ventricle is paced at either a predefined ventricular upper rate limit value or at a rate limit value that is decremented to a fallback rate limit value.  The pacer further increases the VA inter-val when the ventricle is paced at the ventricular rate limit.  The pacer is also programmed to show Wenckebach behavior and thereby occasionally drop a ventricular pace in response to an atrial rate that exceeds the ventricular rate limit.  The pacer resets the defined ventricular rate limit to an upper rate limit value when two successive ventricular paces are provided at a rate less than the defined ventricular rate limit.  A nonphysiological interval is defined after an atrial pace.  If a ventricular event is detected during the nonphysiological interval, the ventricle is paced at a predefined time period following the initiating atrial event.

Abstract: ABSTRACT     A coal liquefaction process for producing hydrocarbon liquid and gas products wherein fine particulate solids are removed in-situ from the reactor effluent slurry liquid by using a process-derived solvent vapor at supercritical con-ditions.  In the process, a coal-oil feed is liquefied and hydrogenated at 650-900°F temperature, and the resulting liquid slurry fraction containing fine particulate solids is contacted with a process-derived solvent vapor fraction having normal boiling range of 250-400°F at supercritical temperature to dissolve and extract substantially all the hydrocarbon liquid fraction and separate the particulate solids contained therein.  The resulting solvent vapor with dissolved coal liquid fraction is pressure-reduced and distilled to recover the needed solvent fraction and provide a hydrocarbon liquid fraction product.  The coal liquefaction step is preferably catalytic.  Also if desired, the super-critical solvent vapor extraction step can be used inter-mediate two coal liquefaction reaction zones connected in series to produce the solids-free hydrocarbon liquid and has products.

Abstract: ABSTRACT OF THE DISCLOSURE A container provided with means for sealing and opening the interior thereof with positive locking action in either position, comprises a self-enclosed resilient side wall defining an inner region and having an undeformed stable configuration. The side wall has a first end and a second end with an opening at each end. An end wall is secured to the side wall member adjacent the second end so as to sealingly secure the second end opening. The container also comprises closure means integrally and movably secured to the side wall adjacent the first end opening. The closure means is configured and dimensioned so as to be bi-directionally selectively movable from a generally locked first position, wherein the closure means positively seals the first end opening, through an intermediate position to a generally locked second position wherein the closure means positively unseals the first end opening. In cooperation, the side wall resiliently deforms as the closure means moves between the first and second position through the intermediate position and thereby generates forces tending to return the side wall to its undeformed stable configuration. In this fashion, the return forces generated by the deformation of the side wall aid further movement of the closure means from the intermediate position to either the first or the second position. A frangible closure strip which renders the container tamper proof is also provided. A method for forming the container of the present invention is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           Selective extraction solvents such as NMP, phenol or furfural employed for the extraction of specialty oils,  i.e. lubricating, transformer and insulating oils, to remove undesirable aromatic compo-nents therefrom, is itself recovered from the extract stream and/or raffinate streams by preferential per-meation through selective membranes of regenerated cellulose. The extract stream, because of its higher solvent content, is the preferred stream for solvent recovery treatment by the reverse osmosis membrane permeation technique. Solvent recovery employing mem-brane permeation exhibits the advantage of not being energy intensive as is distillation or stripping. The solvent is recovered at a high enough flux rate and at a high enough level of purity to be introduced back into the solvent extraction process optionally at some point in the process wherein the composition of the recovered solvent approximately matches the composi-tion of the solvent present in the process at the point of introduction.
