Abstract: "LOG-PEELING LATHE"               ABSTRACT OF THE DISCLOSURE     A lathe for peeling logs to produce veneer for making plywood or the like.  The lathe includes sets of inner and outer dogs supporting each end of a log being peeled.  A reciprocating-pressure bar or roller is included for engaging the peeled veneer adjacent to the knives.  The lathe is operated by a programmed controller.  The radius of each log being peeled is determined by the controller based on the position of the pressure bar or roller after round up of the log.  When the radius of the log is greater than a preprogrammed value, the log core is released from the lathe after peeling to the diameter of the outer dogs.          When the radius of the log is less than the preprogrammed value, the log core is released from the lathe after peeling to the diameter of the inner dogs.  The controller automatically determines to which core diameter each log is to be peeled.

Abstract: ABSTRACT         A detector for conducting metals within mineralized ground where the detector uses an integrated cross correlator to control a ground balancing element.          The detector contains a coil for transmitting sinusoidal magnetic signals and coil for receiving retransmitted signals from the ground and objects.  The received signal is demodulated to extract signals predominant in the ground signal, X, the reactive channel, and predominant in object signals, R, the loss channel.  Changes in time of these signals, Xa and Ra, when suitably modified to remove signals intrinsically arising from functions of the detector, are cross correlated by a multiplier 15, the output of which is integrated 17.  The integrator controls the ground balancing control, the reference phase to the R channel demodulator by means of the phase shifter 18.

Abstract: Abstract of the Invention Inflating and deflating device for a balloon dilatation catheter comprising a housing and a syringe carried by the housing.  The syringe has an outlet adapted to be connected to the  catheter.   The  syringe  includes  a container and a piston which is slidably mounted in the container.  The syringe also includes a rigid plunger connected to the piston and extends out of the housing.          The  plunger  has  helical  threads  formed  thereon  to provide an elongate ratchet.  A pawl is movable between rachet-engaging  and  rachet-disengaging  positions.   A spring is carried by the housing and engages the pawl and yieldably urges the pawl into its rachet-engaging position.  A tab is carried by the housing and engages the  pawl  and  is  used  for  moving  the  pawl  out  of engagement with the ratchet to release the ratchet.          The pawl and the ratchet are formed so that when the syringe contains a liquid, the plunger can be pushed inwardly by hand to provide a desired pressure on the liquid in the container and the plunger can be rotated to gradually increase or decrease the pressure on the liquid in the container.

Abstract: ADAPTIVE STOP-NOTCH FILTER                       Abstract A filter suppresses energy at time varying or ensemble varying frequencies.  The filter comprises multiplier sections having sets of values which are dynamically varied during the receipt of time varying or ensemble varying energy.  The variation of the values of the multiplier sections provides the sup-pression of energy at the time varying or en semble varying frequencies.  The sets of values for the multiplier sections are chosen such that the poles of such values lie within the unit circle of the z-plane locus.  The location of the poles within the unit circle guarantees that the filter remain stable even though the multipliers may be located in a feedback path.  In the preferred embodiment, the dynamically varying filter is used in a dual tone multi-frequency (DTMF) receiver.

Abstract: ABSTRACT OF DISCLOSURE        A two-stage process for the co-production of ani-line and m-phenylenediamine where, in the first stage, ben-zene, nitric acid, and sulfuric acid are reacted in a liquid phase to produce in greater amounts nitrobenzene (approxi-mately 70%) and m-dinitrobenzene (approximately 30%), and in lesser or trace amounts o-dinitrobenzene and p-dinitroben-zene, and water; and in the second stage the products of the first stage are reacted with hydrogen in the gas phase to produce aniline (approximately 70%) and m-phenylenediamine (approximately 30%) in greater amounts, and o-phenylene-diamine and p-phenylenediamine in lesser amounts, and water. The reaction products are separated by distillation.  The first stage of a preferred embodiment of the process is characterized in that a concentrated mixture of nitric acid and sulfuric acid are fed along with mononitrobenzene to a first reactor for producing dinitro-benzene, and then the dilute acid mixture recovered from this first reactor is fed along with benzene to a second reactor for producing the mononitrobenzene used as a reactant in the first reactor. The second stage, which provides the aniline and m-pheny-lenediamine in major amounts, is characterized in that the hydrogenation is carried out in the gas phase with product aniline serving as a diluent.  The process is applicable to the co-production of other aromatic mono- and diamines.

The intermediate thiourea compounds are made by contacting an unsaturated norbornene compound with HSCN generated in situ from a salt of thiocyanic acid and a mineral acid in aqueous media, at temperatures below 150 DEG  C. to produce a corresponding norbornyl isothiocyanate which is then reacted with a dialkyl amine HNR3R4 at temperatures below 150 DEG  C.  Suitable chloro-substituted norbornenes are obtained by reacting 2-chloro-1-propene, 2,3-dichloropropene-1, or vinyl chloride is reacted with cyclopentadiene (which may be obtained by depolymerizing dicyclopentadiene).  Detailed examples are given. Reference has been directed by the Comptroller to Specifications 890,540.
