Abstract: IMPROVED COUPLER PATTERN FOR A RAILWAY VEHICLE                 ABSTRACT OF THE DISCLOSURE         The drag pattern for a standard AAR coupler is modified to increase the thickness of the bottom wall of a coupler casting forwardly and rearwardly of a plane containing the horn line.  The increased thickness is achieved by forming a substantially planar bottom wall surface for a distance of at least two inches at either side of a plane containing the horn line.  Head and shank pattern parts are interchangeable and releasably secured onto a pattern plate for molding foundry sand in the drag portion of a foundry mold to produce E, E/F and F-types of coupler castings.

Abstract: FLYING SPOT SCANNER ABSTRACT OF THE DISCLOSURE     A flying spot scanning system is provided by utilizing reflected light from a multifaceted rotating polygon which is then directed to the scanned medium.          A light source illuminates at least two contiguous facets of the polygon during each scanning cycle, to provide the desired sequence of spot scanning.  To assure a uniform spot size at the scanned medium, an optical convolution of elements is selected in combination with the light source such that an adequate depth of focus at the medium is assured.  In each scanning cycle, information is transmitted to the scanned medium by modulating the light from the light source in accordance with a video signal.

Abstract: TITLE OF THE INVENTION:          PIPE ASSEMBLY-HEAT EXCHANGER-STEAM DRUM UNIT           ABSTRACT OF THE DISCLOSURE:      A pipe assembly-heat exchanger-steam drum unit, which comprises a pipe assembly-heat exchanger for a heat exchange between media of relatively high pressure differential and a steam drum with a liquid chamber and a steam chamber while the medium passing through the pipes of the pipe assembly-heat exchanger has a high entering temperature, and a pipe bottom located on the inflow side of the hot medium is thin.     In the pipe assembly heat exchanger there is furthermore pro-vided a device for relieving the thin pipe bottom.  In the pipe assembly-heat exchanger there is also provided a device which is so designed that the cold medium entering the pipe assembly-heat exchanger is conveyed to the thin pipe bottom.           The pipes of the pipe assembly-heat exchanger are as an assembly of pipes transversely and centrally passed through the steam drum while the pipe assembly-heat exchanger and the steam drum form a unit with each other.  The pipes are at the inflow side of the hot medium by means of the thin pipe bottom connected to the mantle of the pipe assembly-heat exchanger while the pipes in the discharge side of the medium passing through the pipes are through a thin pipe bottom connected to the upper side of the mantle of the steam drum.

Abstract: ABSTRACT OF THE DISCLOSURE     An arrangement for supplying air to a boiler-furnace whereby an axial flow fan being used as a source of primary air may selectively take suction air from the atmosphere or from the discharge side of a fan being used to provide secondary air to the boiler.  This arrangement will provide an increased inlet pressure for the primary air fan to thereby achieve increased stability and high system pressure for low load operation, thereby permitting the effective use of an axial flow fan as a source of primary air when such usage would otherwise be un-justified.

Abstract: Abstract of the Disclosure A transducer housing for an air-dropped sonar transducer includes a smooth cylindrical case for stowage on board an aircraft.  The case is formed with a separation device which permits ejection of the transducer from the case upon impact with the water of the ocean, the device being formed of tabs on the case and chambers on a cover plate of the case.  The impact of the water on the cover plate is directed by the chamfers against the tabs to spread them apart thereby releasing the cover plate and the transducer.  Pins on the cover plate project through apertures in the tabs and press against the side of the apertures with a preset force to essentially lock the tabs to the plate until the preset force is overcome by the water impact.

Abstract: TITLE         AN AUTOMATIC TRANSMISSION            ABSTRACT OF THE DISCLOSURE      A multi-ratio motor car automatic transmission comprising two planetary gear trains and a coupling between input and output.  Each train comprises a sunwheel, planet pinions, planet pinion carrier and internally toothed annulus.  Two clutches and two or three friction reaction brakes hold stationary and/or prevent or allow various parts of the gear trains to rotate to select one of the ratios.  The manner of selection is such as to reduce reliance of the trans-mission on the coupling so as to reduce losses in the coupling and thereby improve fuel consumption.  Arrange-ments are described suitable for rear engined and trans-verse front engined vehicles as well as for the more conventional front engine layout.

Abstract: ABSTRACT OF THE DISCLOSURE Coalescer cartridge comprises a fixed end support plate, a moveable end support plate attached to an actuating rod and a plurality of fibres or bundles of fibres.   Each fibre or bundle is secured at one end to one end plate and at its other end to the other end plate.  In use the end plates are positioned close to one another by movement of the rod so that the fibres are compressed together to form a fine network.   The cartridge is suitable for use in coalescing emulsions of oil and water and removing any suspended solids.   When the cartridge becomes blocked it is easily regenerated by causing relative motion between the end plates to stretch the fibres and open up the network.   Contaminants are then removed by flushing with wash liquid.
