Abstract: ABSTRACT          An imaging device comprising a semiconductor body with an array of photosensitive elements arranged in rows and columns at a first portion of the body for generating and storing mobile charge carriers in response to incident radiation.  The device contains a first means which has charge-transfer lines interdigited with the columns of the array for transferring stored charge carriers from the array.  A second means defines at another portion of the body a charge-transfer shift register which receives from the first means a parallel supply of the charge information of a row of the array and provides a sequential output of this information.  Each transfer line comprises an elongate resistive electrode which is insulated from the underlying portion of the body and extends alongside its associated column of the array and a means is present for transferring the charge storage information of each row of the array separately into the transfer lines.  The resistive electrode is provided with connections for applying a potential difference along the resistive electrode to produce in the underlying body portion a drift field in the direction of the shift register for transporting mobile charge carriers towards the shift register.

Abstract: Abstract A method for storing prilled sulphur in an open area, employing the formation of a solidified sulphur plate on the sulphur dump.  A layer of crushed sulphur, or a water spray at a temperature of less than or equal to the ambient temperature is placed over the surface of the dump.  A solidified layer is then formed by spraying with liquid sulphur.  This temperature permits the formation of a solid crest of sulphur on the dump surface, thus protecting the interior of the dump, without liquid sulphur penetration into the body of the dump.

Abstract: Abstract A process is disclosed for recovering cellulose using sulfuric acid and utilizing the recovered cellulose by hydrolyzing to yield glucose. Cellu-losic raw materials are hydrolyzed by dilute sulfuric acid to remove hemicellulose, after which the solid residue is separated and concentrated sulfuric aicd is added thereto to dissolve cellulose in the solid residue.  After blending and mixing of the resi-due in the concentrated sulfuric acid under closely controlled reaction conditions, cellulose is repre-cipitated by addition of water or an organic solvent such as methanol.  The recovered cellulose can then be hydrolyzed by cellulase enzymes and/or dilute acids to provide a high yield of glucose.  High level re-covery and reconcentration of the sulfuric acid is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention discloses a hose coupling for use with a faucet, including an upright rod which is adapted for vertical motion in response to the water pressure in the hose.      When the water pressure in the hose is normal, the upright rod movesto the upper limit of its range of travel, and slightly projects upward beyond a valve seat, pushing up a steel ball valve, and allowing the water to be discharged from the hose tip.  If the water pressure in the hose in-creases abnormally, the upright rod retracts downward and allows the ball valve to fit on the valve seat.  This invention provides an improved coupling when compared to the prior art devices in that it automatically shuts off the water supply if the hose is folded or flattened out result-ing in an abnormal increase in water pressure in the hose, and opens to resume the water supply when the water pressure in the hose returns to a normal level, in an improved and more efficient manner.

Abstract: THERMAL STORAGE METHOD AND SYSTEM UTILIZING  AN ANHYDROUS SODIUM SULFATE PEBBLE BED  PROVIDING HIGH-TEMPERATURE CAPABILITY   ABSTRACT               Anhydrous sodium sulfate has been shown to have higher thermal content than any other low cost solid material because of its high density, high specific heat, and additional reversible latent heat of solid-to-solid crystal phase change at around 465°F. By compressing anhydrous sodium sulfate into pellets and then forming a bed of these pellets and pass-ing a heated fluid through the bed a relatively great quantity of heat energy may be economically stored in a relatively small volume. Moreover, a rapid rate of heat transfer into or out of the pebble bed can be achieved, up to 400,000 Btu per hour per cubic foot. The same heat transfer fluid may be used to withdraw the heat from the bed for use in space heating or other purposes. The fluid may be air, other inert gases, or a non-acqueous heat transfer liquid which does not react with sodium sulfate, such as a modified terphenyl or a high temperature oil. Advantageously, a thermal storage system embodying this invention can store a relatively great quantity of heat energy per unit volume, for example up to at least 45, 000 Btu per cubic foot in a pebble bed containing thirty percent voids, and even higher when the pebbles are smaller and the percentage of voids is lower. This amount of stored heat energy per unit volume with rapid charging and discharging rates is considerably greater than in any practicable arrange-ment heretofore proposed.

Abstract: ABSTRACT OF THE INVENTION          The printing and correcting device is applied to a daisywheel printer and comprises a  frame supporting a cartridge for a typing ribbon and a correcting ribbon arranged below the typing ribbon. The frame is able to swing as the result of operation of an electromagnet, from a rest position provid-ing visibility of the print, to an intermediate position for printing the characters. A second electromanget raises the frame through a greater length of travel in order to posi-tion the correcting ribbon in front of the printing point. A rotating electromagnet causes automatic unidirectional advance of the typing ribbon after each character has been printed. The correcting ribbon is wound between two spools and its  motion is provided by means of a pawl which engages with a gear wheel for driving the spool only in the case where the path of travel of frame is greater than that which relates to positioning of the typing ribbon. A paper finger in the form of a sheet of limited thickness is provided with a cut out portion corresponding to the printing point, and with a guide in the form of a leaf spring for guiding the two ribbons adjacently to the typing paper when they are being raised and for preventing unwanted contact by these.
