Abstract: A PRECISELY PARTITIONED BULBOUS-SHAPE CONTAINER AND METHOD OF MAKING IT                    Malcolm B. Lucas ABSTRACT        A longitudinally partitioned bulbous-shape, top-opening container of unitary construction is provided which comprises a precisely shaped, sized, and oriented integral bulkhead.  Such containers may be made by the method of providing a thermoplastic preform which is longitudinally partitioned by an integral bulkhead of the size, shape, and orientation desired in the finished container, and then blow molding the outer wall of the preform to the bulbous-shape of the finished container while constraining or confining the bulkhead from changing size, shape, or orientation.

Abstract: Abstract of the Disclosure The invention concerns a process for the manu-facture of textile or wire-reinforced hoses, the components of which are placed while the inner tube is supported by a mandrel.   According to this invention, the mandrel is made of a congealable fluid which is introduced in-side the tube and then cooled and solidified during manufacturing steps wherein the formed assembly will resist mechanical stresses which would not be endured by the sole constituents of the hose.  The mandrel is thereafter brought back to a liquid form to be drained off.   The invention is applicable to the manufacture of medium and high pressure hoses.

Abstract: APPARATUS FOR COMPENSATING FOR OPTICAL ERRORS IN A ROTATING MIRROR                    ABSTRACT OF THE DISCLOSURE           Inherent defects in the angular relationship between facets of a rotating polygonal mirror used to sequentially scan a beam of radiation are corrected by an optical reflecting or refracting element pivotally mounted in the path of the radiation. With the use of electromechanical devices energized by timed electrical signals of appropriate value, the mirror or refracting element is pivoted to correct the scanning errors caused by angular defects in the rotating mirror.  The effect of variations in the angles between facets of the polygonal mirror are also corrected by an electronic circuit which includes a delay device capable of delaying the scanning by a predetermined amount. Con-trol means for the electromechanical devices and for the delay device are pre-programmed so as to make the proper adjustments for each facet of the rotating polygonal mirror.

Abstract: ABSTRACT OF THE DISCLOSURE         A signal decoder is disclosed for use in a trans-portation vehicle control system in which vehicle control signal information bits are transmitted according to a multiple message frequency, FM, PSK, or FSK, comma-free binary coded command signal.  The disclosed invention uses selective receiver channels for each command signal message frequency to detect information bits according to the selected message frequency.  The detected information bits of each receiver channel are separately stored to comprise a separate information history for each message frequency and these information bit histories are then individually decoded. The decoded signals are compared to detect a discrepancy between any of the decoded signals due to component failures, signalling system noise, or component transient conditions. For any discrepancy between the decoded signals, a fail-safe comparator reduces the decoded signal to a more safe condition.

Abstract: HEAT STABILIZERS FOR EXPANDABLE STYRENE POLYMERS ABSTRACT OF THE DISCLOSURE          Expandable styrene polymer particles having reduced flammability are made by incorporating from 0.1 to 15 weight per cent of organic halogen compounds into the polymer during impregnation of the polymer particles with a blowing agent in aqueous suspension.  Temperatures greater than 90°C., during the impregnation step, often cause degradation of the halogen compound and subsequent degradation of the polymer at the particle surface.  The addition of certain thermal stabilizers, such as a mixture of a modified epoxidized soybean oil and a barium/ cadmium organic complex, stabilizes the halogen compounds in the suspension system to temperatures up to 115°C.   1.

Abstract: Abstract An electronic cash register comprises a keyboard having a date key and a void key, a central processor unit coupled to the keyboard and a read only memory coupled to the central processor unit.  The read only memory has a program stored in it.  A memory is coupled to the central processor unit and includes a printing data memory for storing an input data item supplied from the data input key and the total of a plurality of the input data items.  There is a printing apparatus, which includes a buffer register, a printer driver and a printer for printing the plurality of input data items and their total successively on a recor-ding paper.  The printing driver includes a feeder to feed the recording paper by one row for printing a new data item when that item is supplied to the buffer register.  The printing driver also has an inhibitor for inhibiting the one row feeding of the recording paper when the void key is depressed and for printing a correcting symbol directly on a data item printed on the paper before the new data item is supplied to the buffer register.  Thus the erroneous recognition of the corrected data is prevented.

Abstract: AUDIBLE ALARM WITH LAMINATED        MAGNETIC CORE     Abstract of the Disclosure An electrically actuated audible alarm having a magnetic structure comprising an assembly of laminations is provided to reduce eddy current losses.  With the reduc-tion of eddy current losses, faster magnetic flux buildup is possible and an increased velocity of striker movement.  The increased striker velocity permits delivery of a given quantum of energy to the gong with a reduced striker and/or armature mass which in turn facilitates even greater velocity.  When actuated from an a.c. current source, a diode may be used in series with the winding to interrupt magnetic flux gener-ation on negative half cycles and permit return movement of armature and striker.  Conventional interrupter contacts may be used when actuated from a d.c. source.  A series diode provides for d.c. loop supervision.  A multiple lead permits the audible alarm to comprise part of the loop  circuit and thereby provide a supervisory signal if an audible alarm is missing.

Abstract: ABSTRACT            This invention is directed to producing a high yield of aromatics from naphtha by integrating a catalytic reformer and a thermal hydrocracking unit followed by fractionat-ing the product stream to obtain the desired aromatic.  In this process, after sulfur is removed, the naphtha is catalytically reformed under conditions adapted to provide the maximum aro-matic content.  The reformed stream is then thermally hydrocracked, preferably in a system containing multiple reactors.  The pro-cess does not require an external source of hydrogen since the reforming and hydrocracking units are operated to maintain a hydrogen balance.  The hydrocracked stream is fractionated in a series of columns to produce the desired mix of aromatics.          In one example, the fractionation separates out (1) benzene, which is further purified, if necessary (2) a toluene stream and a C9+ aromatic stream which are charged to a transalkylation reactor to produce a composition containing mixed xylenes sent to recycle and (3) a mixed xylene stream from which paraxylene is separated by a liquid-solid adsorption technique and from which the remaining xylenes are isomerized to produce further paraxylene.  A by-product stream of light hydrocarbons is also produced.  This procedure can be readily modified to produce greater amounts of benzene and/or toluene and less xylene.
