Abstract: ABSTRACT OF THE DISCLOSURE    Low sodium sponge goods, such as soda crackers, oyster crackers, pretzels, and flavored snack crackers, having   a   substantially   uniform   texture   and   pH throughout,  a substantially  uniform surface  color,  a pleasant mouth feel and taste are obtained by the process of the present invention.  The sodium content of the sponge goods is reduced, for example, to less than or equal to 42 mg Na+ per 14.2 gm serving, by replacing at  least  a  part,  preferably  all,  of  the  sodium bicarbonate with potassium carbonate for neutralization of the sponge acidity resulting from fermentation and for leavening.   Hot spots resulting from localized concentrations of potassium ion are avoided by:   1) applying the potassium carbonate substantially uniformly and directly upon the surface of the sponge to hydrate and solubilize the potassium carbonate and/or 2) using potassium carbonate having a particle size distribution of about 98% by weight being finer than 100 mesh.  Other baked goods, such as baked sweet goods can be made with a sodium content of less than or equal to 42 mg Na+ per 14.2 gm serving by replacement of sodium bicarbonate with potassium carbonate.

Abstract: ABSTRACT A valve body includes a chamber for the flow of fluid between an inlet and outlet thereto.  A valve member, such as a ball valve member, is positioned in the chamber for rotatable movement between an open position and a closed position to open and close the chamber.  A bent valve stem extends between and is connected to the valve member and a rotatable valve actuator.  Rotation of the actuator moves the valve member by rotation of the valve stem between the open and closed positions.   The valve stem upper end portion is displaced from the valve stem lower end portion to provide the valve stem with a bent configuration.  A bellows surrounds the valve stem to provide a hermetic seal around the stem between the valve body and the actuator.  The bellows has a bent configuration corresponding to the bent configuration of the valve stem.   The outer surface of the valve stem is positioned closely adjacent to the inner surface of the bellows to provide the bellows with support substantially along the entire length of  the bellows and means is provided to minimize wear between the bellows and stem.  In operation, the bellows is internally pressurized and the support provided by the valve stem prevents lateral deflection of the bellows and failure of the bellows due to distortion.

Abstract: ABSTRACT OF THE DISCLOSURE         METHOD AND APPARATUS FOR DEINKING     A method and apparatus for deinking a fibre stock or slurry.  In order to optimise the separation process the invention proposes to independently control the air injection phase, the mixing phase,and the separation phase by splitting them into separate steps.     Thus, there is provided a separation cell which is fed with slurry from an inlet.  Air is introduced into the slurry before entry into the separation cell and before entering a mixing section which mixes the air and slurry before entering the separation cell.     The air is introduced under pressure by way of a porous sintered sleeve, whilst the mixing is achieved by the provision of three turbulence discs in the preferred embodiment.  Alternative turbulent generating means may be employed. The mixing ensures contact of the ink with the air bubbles which separate out in the separation cell and rise to the surface as a foam.  The foam is removed by suction, whilst the deinked fibre slurry is drawn off from the tank by means of a weir or stand pipe.          A separation plate isolates the foam from the draw off section of the tank.  It is preferred that the separation cell is divided into a plurality of cells which are fed from a respective inlet, each having a respective said air inlet and mixing section.

Abstract: CONSTANT A-A INTERVAL CONTROL FOR   DVI AND DDD CARDIAC PACEMAKERS                          ABSTRACT    A physiologic cardiac pacer operable in the DVI or A-V sequential pacing mode or the DDD or fully automatic pacing mode senses for the omission of an R-wave from an implantable cardiac pacer during the A-V interval.  If the pacer does not sense a R-wave during the A-V interval the V-A interval is timed out immediately following the A-V interval and an atrial pacing pulse is issued at the end of the V-A interval.  In the event, however, that an R-wave is sensed during the A-V interval, a flag is set and then the entire A-V interval is to be timed out, at which time the state of the flag is determined.  If an R-wave was priviously issued, a ventricular pacing pulse is not issued to the pacer at the end of the A-V interval, whereas if the flag is not set it is transmitted to the pacer.

Abstract: Abstract of the Disclosure An annulus pressure responsive downhole tool includes a housing having a power piston slidably disposed therein.          First and second pressure conducting passages communicate a well annulus with first and second sides of the power pis-ton.  A retarding device is disposed in the second pressure conducting passage for delaying communication of a suffi-cient portion of an increase in well annulus pressure to the second side of the power piston for a sufficient time to allow a pressure differential across the power piston to move the power piston from a first position to a second position relative to the housing.  A pressure relief valve is communicated with the second pressure conducting passage between the power piston and the retarding device for relieving from the second pressure conducting passage a volume of fluid sufficient to permit the power piston to travel to its second position.  The pressure relief valve is opened by mechanical action when the power piston starts to move toward its second position.

Abstract: ABSTRACT OF THE DISCLOSURE         Liquid fuel is converted into gaseous form in an enclosed chamber rotating at high speed (e.g., 10,000 rpm).  The fuel is delivered to a surface of a flat disc rotating about an axis perpendicular to the disc at the center.  The fuel flows across the disc surface in a thin film to promote evaporation.  Any unevaporated liquid fuel is retained by centrifugal force against the peripheral outer wall of the rotating chamber until the liquid completely vaporizes.  The evaporated fuel mixes with air flowing into the chamber through an inlet opening opposite the disc evaporating surface.  The mixture flows outwardly, around the edge of the disc, then inwardly between the back of the disc and the upstream edge of an annular baffle to exit from the chamber through an outlet opening of significantly smaller diameter than the maximum inner diameter of the chamber as a thoroughly mixed dry gaseous combination of fuel and air.

Abstract: ABSTRACT           In an electronic typewriter, an automatic word correcting system includes a keyboard word erase function key for selectively causing automatic erasure of a word or a series of words.  Operation of the word correcting system is based on electronic sensing of "space" or non-print functions and successive recall of consecutively printed characters stored in a print line memory of a control circuit in the typewriter.  To erase a previously typed word after other words have been typed, the operator aligns (backspaces) a carrier print point at any print line position occupied by the word.  Then a single one touch (depress/release) actuation of the Word Erase Key operates an electronic word erase control that causes the carrier to automatically move to the right to find and then stop the carrier when the subsequent "space" function is electronically sensed in memory.  The typewriter is then caused to be automatically operated in word correction mode to progressively move leftwardly erasing consecutive printed characters of the unwanted word in reverse order.  The erasing action is caused to automatically stop when the next left "space" or non-print function is electronically sensed in memory and the typewriter may then be operated in normal fashion for character printing in the erased positions.
