Abstract: ABSTRACT OF THE DISCLOSURE         Smoke contained in gases and, in particular, in waste gases, from a diesel engine may be reduced by the method described herein.          The method from the purification of exhaust gases issuing from a diesel engine involves passing the gases through a catalyst, which is of a special nature, namely which comprises (a) a catalytic material comprising one or more metals of the platinum group, (b) a support comprising a filter material which is obstructive enough to enable the catalytic material to filter particles from the exhaust gases and is coarse enough to avoid generation of a back pressure of above four inches of mercury, and (c) a washcoat provided between the catalytic material and the support.  The method involves passing exhaust gases issuing from the engine without pre-heating into the catalyst, the gases being being at a temperature at which catalytic oxidation of carbon particle can take place; and passing the exhaust gases through the catalyst, whereupon the disposition of the filter material inhibits straight through flow of the gases, thereby imparting turbulence to the gases.          In this way not only is the probability of contact between the particle and the catalytic material increased, but also, turbulence is imparted to the gas stream to increase the probability of contact between the particles and the catalytic material.

Abstract: ABSTRACT OF THE DISCLOSURE      N-substituted-14-hydroxy-3-substituted-morphinan derivatives have been found to possess potent narcotic agonist or antagonist activity.  In particular, the compound N-cyclo-butylmethyl-3,14-dihydroxymorphian has been found to possess potent agonist/antagonist activity as a non-narcotic analgesic.          An improved total synthesis of these compounds is described herein from the starting material 2-(p-methoxybenzyl)-1,2,3,4, 5,6,7,8-octahydroisoquinoline.  A preferred feature of the process involves borane reduction of 2-cyclobutylcarbonyl-9,10-dihydroxy-1-(p-methoxybenzyl)perhydroisoquinoline (Va) to provide the corresponding cyclobutylmethyl derivative complexed with borane, which forms the subject matter of this divisional specification.  This intermediate is converted directly to N-cyclobutylmethyl-14.beta.-hydroxy-3-methoxymorphinan (LVa) by treating with acid.

Abstract: FUEL OIL FILTER CARTRIDGE                       ABSTRACT OF THE DISCLOSURE         A refill filter cartridge for a liquid fuel filter includes a semi-rigid plastic "blister" having an open end closed by a cover member to define a fluid receiving compartment.  A pleated paper filter medium in the compartment divides the latter into inlet and outlet portions which communicate with openings in the cover member.  The filter housing includes a base and a cup-shaped glass housing that cooperates with the base to define a chamber which receives the plastic blister when the refill cartridge is installed in the filter.  The cover member defines cooperating surfaces which engage the base and the glass housing so that the glass housing clamps the cover member between the glass housing and the filter base.  The plastic blister is shaped to conform to the inner walls of the housing so that the housing engages the walls of the blister throughout their entire area.  Accordingly, the glass housing serves as a support for the blister, so that the latter can withstand fluid pressure forces that would normally rupture the blister.  In this way, a relatively inexpensive plastic blister can be used instead of a glass housing in the refill, and the filtering medium can be sealed to the sides of the blister instead of being sealed directly to the housing.  Accordingly, the glass housing can be used over and over again, and need not be thrown away when the filter is changed.

Abstract: (Case No. 7009) ABSTRACT OF THE DISCLOSURE     A cross field transformer circuit arrangement for use as a solid-state, synchronous detector track relay device for alternating current track circuits.  The track signal at the receiver end is applied to the primary winding on the main magnetic circuit and the local input  signal to another primary winding on the modulating magnetic circuit of the saturable core of the transformer.  Each input is transformer isolated from its source and passed through a noise-rejecting filter tuned to track circuit frequency.  The main magnetic circuit flux is modulated by the modulating magnetic circuit cross field flux so that the secondary winding, on the main magnetic circuit, produces an output signal at double the track fre-quency, i. e., its second harmonic.  A band pass output filter passes only this second harmonic signal to a full-wave recti-fier to energize a biased track relay only when both inputs, in phase and of the same frequency, are received.  For track circuit use, a diode added in series with the local input filter and a second diode inserted in series with the secon-dary output modify circuit operation to inhibit response by a two-winding, biased track relay to an opposite polarity track input signal received through a failed insulated joint.

Abstract: ABSTRACT           A method and apparatus for using a linear frequency chirp in a transmitter/receiver having a correlator to synthesize a narrow beamwidth pattern from otherwise broadbeam transducers when there is relative velocity between the transmitter/receiver and the target.  The chirp is so produced in a generator in band-width, B, and time, T, as to produce a time-bandwidth product, TB, that is increased for a narrower angle.  A replica of the chirp produced in a generator is time delayed and Doppler shifted for use as reference in receiver for correlation of received chirps from targets.  This reference is Doppler shifted to select targets preferentially, thereby to not only synthesize a narrow beam but also aim the beam in azimuth and elevation.
