Abstract: TITLE OF THE INVENTION          "Heat-reflecting glass pane and a process for the production thereof"     ABSTRACT OF THE DISCLOSURE    A heat reflecting pane comprises a substantially trans-parent glass substrate which has a layer of silicon oxide thereon and a layer of titanium dioxide in the rutile form on the side of the silicon oxide layer remote from the glass pane, the glass substrate having been toughened by heat treatment.  The pane is formed by coating the glass substrate with a thin layer of silicon oxide, then applying a layer of titanium to the silicon oxide layer by vacuum deposition, then oxidizing the titanium at over 550°C to form titanium oxide in the rutile form.    The silicon oxide layer prevents the rutile layer from becoming opaque when the pane is heated to the temperature necessary for heat treatment of the glass substrate, which may be during the heating step in which the titanium is oxidized or may be subsequently.

Abstract: BLOCK LENGTH MULTIPLE PLUS RUN LENGTH RESIDUE CODES FOR RUN LENGTH ENCODING               ABSTRACT OF THE DISCLOSURE     A fractionally difference modulated binary video signal having a raster scan format and containing some scan lines of difference modulated picture elements and other scan lines of unmodulated picture elements is compressed by a truncated run length encoder which converts black terminated white runs into run length message codes, non-terminating black picture elements into individual message bits, and unterminated white runs into end-of-line message codes.  No distinction is made between the difference modulated and un-modulated picture elements while generating the run length message codes and the individual message bits, but different end-of-line message codes are generated in response to the unterminated white runs of difference modulated and unmudulated picture elements, thereby providing a scan line-by-scan line indication of whether the picture elements are difference modulated or not.  A block length multiple plus run length residue code format is employed for encoding the black terminated white runs, whereby runs in excess of a predetermined block length are represented by a block length multiple code plus, for any runs which are not integer multiples of the block length, run length residue codes.  Shorter black terminated white runs are repre-sented merely by run length residue codes.

Abstract: METHOD FOR PURIFICATION OF AIR CONTAINING CARBON MONOXIDE    Abstract of the Disclosure The specification discloses a method for the removal of carbon monoxide from air wherein the air to be purified is passed through a catalyst for the promotion of the oxidation of the carbon monoxide.  The catalyst consists of a carrier including powdered activated carbon, an alkali, and a bonding agent, impregnated with palladium and one or more of the elements ruthenium, rhodium, and platinum or with palladium alone.  The amount of the alkali is such that there is reduced risk of combustion despite the presence of activated carbon, and the bonding agent renders the catalyst more resistant to vibration, while high rates of carbon removal are achieved at comparatively low temperature and high rates of air flow through the catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed herein is a cap for a liquid tank having a filler neck, such as a fuel tank for an outboard motor, which cap includes a hollow body having a top wall portion for closing the filler neck and a depending annular flance for releasably engaging the filler neck.  The interior of the tank is vented to the atmosphere through one or more vent ports located in the top wall portion and the vent port(s) is selectively opened and closed by a closure member including a shank threadably mounted on the top wall portion and a cover portion for opening and closing the vent port when the closure member is turned in opposite directions.  A dish-shaped baffle disposed inside the cap body in spaced relationship to the top wall portion serves a baffle to minimize spillage of fuel through the vent port(s) and also defines a chamber for collecting fuel which otherwise might leak through the vent port(s) and for draining the collected fuel back into the fuel tank when the motor or tank is in an upright operating position.          In one embodiment, unintentional complete detachment of the cap from the fuel tank is prevented by a cap retainer including an elongated stem having an upper end connected to the inner end of the closure member shank and a trans-versely extending member having a length greater than the inside dimension of the filler neck and connected to the lower end of the stem.  All of the parts of the cap, except the diaphragm, preferably are molded from a synthetic thermoplastic material.

Abstract: ABSTRACT OF THE DISCLOSURE A split wheel assembly for reception of pneumatic tires is provided with a safety feature to ensure that the two halves of the wheel cannot be dismantled when the tire thereon is pressurized.  The assembly flanges of the two wheel portions have series of assembling apertures which register in pairs.  The aperture on one of the flanges is circumferentially extending, and has a narrow end and a broad end.  The narrow end of the aperture extends to an axially extending depression on the surface presented towards the flange of the other rim section.  A bolt passes through the apertures, for assembling purposes, the bolt having a washer which fits into the depression, and having a securing nut which is sized so as to pass through the broad end of the aperture but not through the narrow end.  In order to dismantle the wheel, the nut must be loosened sufficiently to cause separation of the two rim flanges so that the washer can move out of the depression, and the bolt can be moved axially to the broad end of the aperture.  Such separation of the rim sections automatically causes deflation of the tire, if it is pressurized.

Abstract: ABSTRACT         Typically, rifle sighting devices consist of a fixed, muzzle-mounted front sight and a vertically adjustable rear sight mounted toward the breach.  Aiming involves the visual alignment of the two sights relative to one another and to the target.  In this invention, a pair of precisely bored cylinders replaces the conventional rear sight, and the entire apparatus is installed on a movable bar, hinged at the front and attached to the rear distance adjustment mechanism.  Thus all sighting components may be adjusted for distance from the target auto-matically, eliminating the error inherent in moving the rear sight alone.  The cylinders act as a guidance system in one of two ways, both of which utilize oncoming light to indicate the exact moment at which the gun is in a correct firing configura-tion.  In the first, a pair of jets mounted on either side of a hood covering the front sight transmit light through the two cylinders, to the peephole and the shooter's eye.  This light, in the form of flashes, is visible only when all components are properly aligned, enabling the shooter to concentrate on align-ing the front sight with the target.  Alternately, the jets are omitted, and the shooter anticipates impending optimum shooting position by the appearance of a narrow semi-circle of light resulting from the characteristic construction and relative size and location of the front sight hood and the two cylinders.
