Abstract: ABSTRACT OF THE DISCLOSURE                An improved magnetic recording tape having a dual layer magnetizable coating which provides an improved high frequency response and increased recording sensitivity in the middle and middle-to-high frequency ranges when used in conventional audio recording devices, particularly open reel to reel type recorders operated at a tape speed of 19 cm/sec or 38 cm/sec. The dual magnetizable coatings consist of an inner layer of a ferromagnetic iron oxide powder dispersed in a resinous binder and an upper layer of a mixture of ferromagnetic powders in a resinous binder, the mixture including at least ferro-magnetic chromium dioxide powder and a ferromagnetic iron oxide powder, both layers having a controlled thickness, controlled coercive force and controlled saturation residual flux density. The weight ratio of the ferromagnetic iron oxide to the chromium dioxide in the upper layer is from 1:4 and 4:1, each of the magnetic powders in said mix-ture having coercive force values within specific ranges.                           -i-

Abstract: Abstract of the Disclosure A rapid transit system which transports people and articles including automobiles, small trucks and the transit routes.  The transit vehicle is a unitary, self-supporting structure which is transported and guided by spaced sets of wheels mounted and turning on pylons.           The transit vehicle is compartmented into cubicles in one rigid structure which could be approximately 21 feet wide by 60 feet high and 1,500 to 2,000 feet long.  The pylon construction supports the transit vehicle above the right of way property, typically at a minimum height of approximately 60 feet.  Each pylon includes an upper power frame assembly having a large wheel for supporting and four smaller wheels for guiding the transit vehicle.           A base frame mounted between the pylon and its foundation is provided when necessary to compensate for changes in transit vehicle over the pylons.  These may be external motors driving through the propulsion wheel shaft or the propelling rotor may be integral with the propulsion wheel driving against stator coils framed from the bear-ing hub structure.  Guide wheels on opposite sides of the of the power frame of the pylon are geared to turn at the same tread velocity as the propulsion wheel and absorb the wind side load of the vehicle.  The power frame may include transformers, rectifiers, power controls, cir-cuit breakers and other control a highly fail-safe operating equipment responsive to the networks (remote) central control system.  The transit vehicle is and elong-ated truss which would extend form the pylon to another is a cantilevered fashion.  Thus the transit vehicle may engage with the next pylon approximately 300 feet away providing the only bridge for the vehicle as it proceeds along the route.          The system would include local routes that would eventually become integrated with branch and regional routes within the system.  The pylons may be individually mounted on mobile trucks to roll in groups on tracks or rails to be moved sideways to simultaneously move the transit vehicle in this fashion.  The pylong may be re-moved and be replaced as required by the transit vehicle itself so that the transit may continue uninterrupted.

Abstract: Abstract of the Disclosure Apparatus for placing identifying indicia on x-ray film within a cassette, in which an electrolumin-escent panel is provided with a resiliently biased slide element movably mounted on a cassette supporting member.          As the cassette is positioned on the supporting member, a portion of the panel protrudes into a slot-shaped opening in one edge of the cassette, and the cassette edge simultaneously urges the slide element away from the protruding portion such that only the protruding portion and an indicia bearing card extend into the opening.  When the cassette reaches its proper position on the support member, an electrical circuit automati-cally closes for a predetermined period of time to il-luminate the panel and thereby expose the film with the information on the card.

Abstract: ABSTRACT OF THE DISCLOSURE This disclosure depicts method and apparatus for screening slot-mask, stripe screen type color cathode ray tubes particularly method and apparatus for improving screen stripe uniformly and edge definition.  The method involves supporting a curved, approximately rectangular faceplate which has on its concave inner surface a photosensitive coating and which has supported adjacent its inner surface an exposure mask defining an array of columns of spaced slots oriented parallel to the minor axis of the faceplate.  A line source of radiation actinic to said coating is supported on or near a central axis of the faceplate with the line of the source oriented parallel to the minor axis of the faceplate. The disclosed method includes producing a virtual image of the line source which appears, when viewed from off-axis points on the faceplate, to be rotated in a direction effective to decrease an unwanted rotational displacement of the mask slot images induced by the relative geometry of the line source, the mask slots and the faceplate inner surface.  Stripe width uniformity and edge definition is thus improved.  Pre-ferred apparatus for implementing the disclosed method includes a negative meniscus lens.

Abstract: ABSTRACT OF THE DISCLOSURE     In the acid-catalyzed etherification of olefins with alcohols, substantially complete recovery of alcohol and catalyst is obtained when small amounts of water (1-10%) are added to the reaction.  The addition of water provides a two-phase reaction medium in which olefin and ether are in the upper phase and alcohol and catalyst are in the lower phase.  These phases are maintained during the course of the reaction, which continues as a two-phase system.  Certain novel ethers produced by this process are likewise disclosed herein.  These products are useful as paint additives, high octane gasoline additives and solvents.
