Abstract: ABSTRACT      METHOD OF MAKING INFRARED REFLECTING COATING     A process for production of infrared reflecting fluorine containing tin oxide coatings on flat glass comprises directing on to a hot glass surface a suspension in a carrier gas of a finely divided solid volatile inorganic tin (IV) compound, free from carbon-tin bonds, containing both chlorine and fluorine. Especially preferred tin compounds are ammonium hexahalostannates of the formula (NH4)2SnHal6 wherein Hal represents halogen, and a minor atomic proportion of the halogen present is fluorine and the balance chlorine. Use of solid tin (IV) compounds in accordance with the invention gives coatings of a higher light transmission per unit thickness when compared with coatings obtained using solid organometallic tin compounds referred to in the prior art.

Abstract: ABSTRACT          A structure provides variable electromagnetic property (variable, resistance, capacitive, or other variable impedance or other variable electromagnetic property) contrast on the surface marking servo tracks on data storage media,  Such media include magnetic or optical storage disks and tapes.  The media can be conductive metallic or nonmetallic and can be composed for example of poorly conductive media, dielectric  media, or semiconductive media.  The variable electromagnetic impedance can vary in the optical, electrical or other portions of the electromagnetic spectrum.  A very small variation of the thickness of the protective layer above the magnetic recording medium is employed to mark the servo track information of the medium.  Information to be detected by means of a capacitive sensor can be recorded in the protective layer above or below the magnetic recording or optical storage medium. For example, a thin film metallic protective layer 0.07 micrometers thick can be patterned with about 0.02 micrometers of the protective layer.  For a plated disk, the top 0.02 micrometers of the protective layer can be patterned.  A pattern for providing a variable impedance for representing data can be formed subtractively by sputter etching, or additively formed by a lift-off process or by deposition through a mask, or by the oxidation of or nitriding of materials such as Al, Si or valve metals. This system provides capacitive or other variable impedance contrast for position signals on conductive metallic media for magnetic disks and tapes by means of a very small amount of modulation of the thickness of the protective layer above the magnetic recording medium.  Optionally, the protective layer may be planarized by subsequent oxidation, or the use of an additional layer.

Abstract: ABSTRACT     This invention relates to a heating appliance which incorporates a viewport through which combustion can be viewed.    The viewport incorporates a portion which is reflectorised so as to reflect some of the radiant heat of the burning fuel in the fire chamber back into the fire chamber to maintain high temperatures in the fire chamber for efficient combustion whilst reducing the temperature of the outer surface of the viewport and accordingly the likelihood of injury to persons accidentally touching the viewport and the possible damaging effects of thermal exposure and shock.  The viewport is reflectorised in the preferred embodiment by a treatment which enhances the reflectivity of the transparent or translucent portion over that of transparent glass.

Abstract: RAILROAD CAR DRAFT GEAR ASSEMBLY WITH FRICTION BORE WEAR LINERS                         ABSTRACT      A draft gear assembly to cushion and absorb impacting forces on a railroad car coupler system includes a housing containing a spring package.  Through a follower the spring package interacts with a set of friction shoes.  The shoes are positioned in friction shoe seats in a friction bore section of the housing.  Each seat includes a wear liner in a recess formed on an inner surface of the housing friction bore section.  The shoes in turn engage a wedge which ex-tends from the housing to connect with other elements of the coupler system.  The liners are made of a selective steel initially deformed by the impacting forces.  This deformable quality allows wider dimensional variations between the shoes, liners, and the housing recesses.  After deformation the liners fit properly in the recesses and the shoes in the seats to optimize areas of contact there-between.  During subsequent operation of the car the impacting forces work harden the liners to a level selective-ly  less than the hardness of the shoes to further increase wear resistance.  Because the liners may be readily removed and replaced, a useful life of the housing may be extended indefinitely.

Abstract: METHOD AND APPARATUS FOR PROCESSING A VIDEO  SIGNAL SO AS TO PROHIBIT THE MAKING OF ACCEPTABLE VIDEO TAPE RECORDINGS THEREOF         ABSTRACT OF THE DISCLOSURE          A video signal is modified so that a television receiver will still provide a normal color picture from the modified video signal while a videotape recording of the modified video signal produces generally unacceptable pictures.  This invention relies on the fact that typical videocassette recorder automatic gain control systems cannot distinguish between the normal sync pulses (including equalizing or broad pulses) of a conventional video signal and added pseudo-sync pulses.  Pseudo-sync pulses are defined here as any other pulses which extend down to a normal sync tip level and which have a duration of at least 0.5 microseconds.  A plurality of such pseudo-sync pulses is added to the conventional video signal during the vertical blanking interval, and each of such pseudo-sync pulses is followed by a positive pulse of suitable amplitude and duration,  As a result, the automatic gain control system in a videotape recorder will make a false measurement of video level which causes an improper recording of the video signal.  The result is unacceptable picture quality during playback.  This approach utilizes positive-going pulses which occur at a time not ordinarily used for black-level restoration in typical television receivers, and therefore does not give rise to black level depression in such typical television sets.

Abstract: ABSTRACT OF THE DISCLOSURE     AND METHOD OF SYNTHESIS OF THE SAME     5-azido-2'-deoxyuridine nucleoside and nucleotide compounds and a method of producing them.          The method involves reacting a 5'-deoxyucidine compound with nitrosonium tetrafluocobocate to pro-duce a 5-nitro-deoxyucidine compound.  The 5-nitro-deoxyuridine compound is reduced to a 5-amino-deoxyuridine compound in the presence of metallic zinc.  The 5-amino-deoxyuridine compound is acidified and reacted with sodium nitrite to produce a 5-diazo-deoxyucidine compound.  The diazo-deoxyuridine compound is then reacted with sodium azide to produce a 5-azido-deoxyuridine compound.  The latter, in the monophosphate form, is further reacted with diphenylchlorophosphate to produce the photoactive triphosphate, 5-azido-2'-deoxyuridine-5'-triphosphate or 5-azido-dUTP.  The photoactive compound, when added to DNA in an in vitro synthesis reaction, pro-duces photoactive DNA.

Abstract: TERMINATED OPTICAL FIBER AND METHODS OF MAKING            Abstract In order to connect two optical fibers (26-26), each of two plugs (40-40) each having a passageway (41) in which is received an optical fiber is mounted in a connector body (42).  Each optical fiber comprises a core (25) and a cladding (27).  The plugs are destined to be received in a sleeve (75) of a coupler (60) such that their longitudinal axes are coaxial.  Alignment of the fiber cores, at least radially of the longitudinal axes, is accomplished by locating for each plug the intersection of a radial line which extends through the centroid of the optical fiber core with the periphery of the plug.  An orienting pin is mounted in each connector body in intentional radial alignment with the intersection.  The connector bodies are inserted into opposite ends of the coupler sleeve to cause each pin of each connector body to be received in a slot in the coupler.  The slots are aligned so that when the connector bodies are inserted into the coupler, the pins orient and cause the plugs to be inserted into the sleeve such that the centroids of the optical fiber cores are aligned along a plane that originates at and extends radially from the longitudinal axes.
