Abstract: WINDOW SHADE            Abstract of the Disclosure This invention is directed to a window shade whose width can be decreased, without cutting instruments, to conform to the size of the window opening into which the shade is to be mounted.  The window shade includes a roller and a shade secured to the roller having at one or both edges a plurality of spaced strip lines, preferably invisible, extending from end-to-end parallel to the shade edges.  The strip lines permit hand-stripping of discrete widths of the shade while the shade is rolled on the roller.  The roller includes substantially coincident with the strip lines of the shade a plurality of longitudinally spaced, circumferentially extending strip lines permitting removal of a corresponding discrete length of the roller.  In accordance with the invention disclosed, the shade includes a plurality of integral tabs at the hem end of the shade whose edges generally coincide with the strip lines to facilitate the stripping of discrete widths of the shade.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for projecting a light beam is disclosed which is constructed so as to simulate a gun.  Within the apparatus a light bulb is mounted upon a base having a spherical surface.  This base is resiliently engaged by a bearing having a correspondingly shaped interior in such a manner that the position of the bulb may be adjusted slightly so that the fila-ment of the bulb is correctly positioned relative to a lens used in projecting a light beam.  In the apparatus the bulb and the lens are separated by a shutter mechanism.  The apparatus includes a trigger which, when actuated, first closes a switch to supply electric power to the light bulb and then causes the release of a shutter actuator serving to move the shutter so that it opens and closes within a comparatively short time interval.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention describes a pickproof lock consisting of a rotating cylinder provided with two sets of opposing tumblers.          The tumblers permit a very thin key to be inserted between them.          The key is made of a ribbon material of the order of one-hundredth of an inch thick and the tumblers are displaced in both directions from the center so that manipulation of a lock-picking tool becomes very difficult, since the tool must be as thin as the key and each set of tumblers must be in the correct position for the cylinder in turn.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a vertical filter.  The filter includes a framework containing a plurality of horizon-tal superimposed filtering units and movable supports for the filtering units.  The supports each comprise a movable frame with an inlet for the slurry to be filtered, a movable collect-ing plate for the filtrate and an endless movable filtration band supported by side rollers and extending between said frame and said collector.  The supports are arranged so as to keep the filtering units stacked against each other during the filtering operation and so as to allow the parts of the filtering units to become spaced apart from each other when the filtration cakes have to be discharged.  In accordance with the invention, the parts of the filtering units, i.e. the frame, the collecting plate and the rollers with the filtration band, are independent from each other, whereas the filtering device also includes independent guides for guiding the parts of the filtering units so as to maintain them permanently coaxial and drives for simultaneously moving the endless filtering band of each of the filtering units towards a cake discharge position.

Abstract: Abstract of the Disclosure A method and apparatus is provided for controlling the operation of a reforming furnace used to decompose at least a portion of a feed stream.  A byproduct fuel from subsequent process steps, which is a result of decomposi-tion of the feed in the reforming furnace, is used as one fuel source to fire the reforming furnace.  A supplemental fuel such as natural gas is used as a supplemental fuel source to fire the furnace.  The control system provides a prediction of the heat required to decompose the feed in the furnace.  The amount of heat which can be supplied by the byproduct fuel stream is then determined.  This amount of heat is subtracted from the total predicted heat required and sufficient supplemental fuel is supplied to make up the differ-ence between the predicted required heat and the heat which can be supplied by the byproduct fuel stream.           The control system also monitors the temperature of the effluent flowing from the reforming furnace.  A comparison of the measured temperature with the required temperature provides a basis for correcting any errors in the predicted heat requirement.  In this manner, use of the byproduct fuel stream is maximized while still maintaining the effluent from the reforming furnace at a desired temperature.

Abstract: 9725     Abstract of the Disclosure This specification discloses a method of treating water which contains oxygen dissolved therein to scavenge the oxygen therefrom and reduce the corrosiveness of the water.  A sulfur-containing fuel is burned in a flue gas generator to generate a flue gas containing sulfur oxides and the flue gas is scrubbed with an aqueous sodium hydroxide solution to convert the sulfur oxides to a mixture of sodium sulfite and sodium bisulfite, the mixture being referred to generally as sodium sulfites.  Ascorbic acid is included in the reaction to prevent the oxidation of the sodium sulfites to sodium sulfates and the sodium sulfites and ascorbic acid are recovered for use as an additive to scavenge oxygen from water. This additive is injected into an oxygen-containing water in an amount sufficient to scavenge the dissolved oxygen from the water.  A catalyst may also be added to the water to catalyze the reaction of the sodium sulfites and oxygen.

Abstract: METHOD FOR IN SITU DETERMINATION  CATION EXCHANGE CAPACITIES OF SUBSURFACE FORMATIONS Abstract of the Disclosure A method is disclosed for the in situ examination of each subsurface formation penetrated by a borehole to ascertain the cation exchange capacity of such formations within a geological region.  Natural gamma ray logging is used to develop signals functionally related to the total gamma radiation and to the potassium -40, uranium and thorium energy-band radiations.  A first borehole is tra-versed by a potential gamma ray spectrometer to provide selected measurements of natural gamma radiation.  Core samples are taken from the logged formation and laboratory tests performed to determine the cation exchange capacity thereof.  The  cation exchange capacities thus are developed then correlated with selected parameters provided by the gamma ray spectrometer to establish functional relation-ships.  Cation exchange capacities of formations in subse-quent boreholes within the region are then determined in situ by use of the natural gamma ray spectrometer and these established relationships.
