Abstract: ABSTRACT OF THE DISCLOSURE        An improved method for recovering spent sodium and sulfur components in sodium sulfite and sodium bisulfite pulping operations.  The method involves reduction burning of spent liquor to convert it to smelt and the treatment of this smelt in a sequence of operations that accelerate the reaction steps used to produce sodium hydrosulfide, hydrogen sulfide, sulfur dioxide, sodium carbonate, sodium bicarbonate and to recover sodium sulfite, sodium bisulfite, sodium carbonate and/or sodium hydroxide while preventing formation of sodium thiosulfate.          The method utilizes a sufficient quantity of recycled sodium bicarbonate addition to precarbonated liquor to maintain the partial pressure of carbon dioxide created by the solution above that provided by the carbon dioxide in the gas used for stripping out the hydrogen sulfide, recovering the carbon dioxide and water vapor for stripping and precarbonation by decomposition of the sodium bicarbonate and recovering carbon dioxide by pressure decarbonation and pressure neutralization, for the high pressure carbonation to produce the sodium bicarbonate.

Abstract: ABSTRACT                 The device compensates for the offset of a sheet element which is movably mounted on at least two parallel rollers which are alternately supply and receiving rollers. At least one (1) of these rollers is inclinable relative to the other and is controlled by means (17-20) for detecting the offset of the sheeet element and acting on compensating means (3-12) which modify the angle of the inclinable roller-This device comprises an offset compensating member (3) which normally rotates with the inclinable roller when the sheet element is correctly centred. The rotation of the compensating member is temporarily inter-rupted and converted into a linear displacement by the action of at least one abutment (9) which is shifted by the detecting means when the latter detects an offset of the sheet element. The compensating means cooperates, in its linear displacement, with the profile of a cam (12) which modifies the position of one end of the inclinable roller and consequently the angle of the latter.                The invention is applicable to the control of the offset of any element in the form of a sheet or band held taut on two rollers or reels.

Abstract: ABSTRACT OF THE DISCLOSURE           A combination bed concrete casting apparatus (20, 122 or 200) which allows either a single relatively wider elongated slab (116 or 200) or at least two relatively nar-rower elongated slabs (46 and 48 or 206 and 208) to be manu-factured.  A casting bed is divided longitudinally along the bottom wall into sections (34 and 36 or 202 and 204) which are movable transversely relative to each other.  An elon-gate removable intermediate form (44 or 214) is positionable between the casting bed sections in a generally parallel re-lationship with the side form walls to form an intermediate wall.  When it is desired to cast a single concrete member (116 or 200) extending all the way from one side form wall to the other, the intermediate form (44 or 214) is removed and the casting bed sections are moved closely adjacent one another.  Alternatively, if it is desired to manufacture a separate concrete member in each casting bed section, the intermediate form is positioned between the sections.  The combination bed apparatus may be adapted for use in combina-tion with either a fixed bed casting apparatus or a moving bed casting apparatus.  The relative transverse movement of the casting bed sections may be accomplished either by mov-ing both sections (34 and 36) away from a centerline, or moving one section (202) away from the other (204), which remains fixed.

Abstract: ABSTRACT OF THE DISCLOSURE A vented battery can is provided which is adapted to engage at least one of a plurality of fill holes in an automotive storage battery or similar lead acid battery and which has pressure release means for venting the combustible gases produced within that storage battery under conditions such as overcharge conditions into the atmosphere.  The cap itself is comprised of substantially two portions, a base member which fits into at least one of the fill holes and a top member which snap-fits through the base member.  The pressure release means comprises a plurality of extremely narrow slits on both the top and underside of the cap which have widths in the order of 0.003 to 0.005 of an inch.  The remainder of the battery cap is tightly sealed to prevent any extraneous leaks of battery gases received form the automotive battery form leaking into the atmosphere.  The slits are so constructed to facilitate the safe expulsion of any volume of gas normally produced by an automotive storage battery, while virtually eliminating the likelihood that ignition of gases within the atmosphere will result in explosive consequences either within the battery cap or within the battery itself.

Abstract: RCA 73,767 ABSTRACT OF THE DISCLOSURE A phase locked loop tuning system includes a phase comparator for generating pulse error signals having pulses with durations corresponding to the magnitude of a phase and/or frequency deviation between a frequency reference signal and a frequency-divided signal derived from a local oscillator signal.  A low pass filter is responsive to the pulse error signals for generating a tuning voltage for controlling a voltage controlled local oscillator to tune standard frequency RF carriers.  So that a substantial portion of the tuning system may be incorporated in a single integrated circuit, a pulse converter is provided to convert an analog AFT signal to pulse error signals similar to those generated by the phase comparator but with durations repre-senting the magnitude of a deviation between the frequency of the IF picture carrier and its nominal value.  The AFT related pulse error signals are selectively applied to the low pass filter to accommodate the tuning of nonstandard frequency RF carriers. The tuning system may include a duty cycle control unit to control the duty cycle of the AFT related error pulses in accordance with the selected channel so that the sensitivity of the tuning system is more uniform throughout the tuning range.

Abstract: ROTOR BRAKE FOR FISHING REEL                        ABSTRACT         Disclosed is a spinning style fishing reel having a housing with a front spool face and a rotor mounted on the housing having a bail that has an open casting position and a closed retrieving position.  An improved means is disclosed for preventing the undesirable rotation of the rotor when the bail is in the casting position.  A brake drum is mounted on the front spool face and a lever which holds the bail in the open casting position is mounted on the rotor.  A brake device is mounted on the lever and presses against the brake drum when the bail is in the casting position.  Thus the brake mechanism prevents the fishing reel rotor from inadvertently or accidentally revolving when the bail is in the casting position.
