Abstract: ABSTRACT OF THE DISCLOSURE Process for the manufacture of a natural sweet efferve-scent beverage, having low alcohol content, of the soda water or soda pop type, flavoured with various fruit juices and flavours. In the process sugar and water are mixed at a first stage, and carbon dioxide which provides gasification is formed in the liquid "in situ", resulting from alcohol-type fermentation of the sugar by the action of fermenting agents. The fermentation is interrupted before the production of a significant quantity of alcohol with unfermented sugar remaining in solution providing the desired sweet taste.

Abstract: AUTOMATIC LOCKING PIN RETRACTION MECHANISM                      ABSTRACT OF THE DISCLOSURE An automatic locking pin retraction mechanism for a skid-steer loader is disclosed wherein the locking pins for locking the loader boom arms in an elevated position will be automatically retracted under conditions where the locking pins are extended into the path of movement of the boom arms and the boom arms are below the locking pins and moving upwardly toward engagement with the locking pins, so as to avoid engagement between the boom arms and the locking pins.  The retraction mechanism includes a pivotally mounted first member engageable with one of the boom arms and a link interconnecting the first member and a mechanism for simultaneously actuation the locking pins.  Pivotal movement of the first member caused by engagement with the boom arm effects a retraction of the locking pins before the boom arms can engage therewith.  An over-center spring arrangement is provided to bias the first member in the engagement position or in a neutral position, depending on the position of the first member.

Abstract: ABSTRACT OF THE DISCLOSURE         Fluorinated ion exchange polymers which have both pendant side chains containing carboxylic groups and pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compart-ments of an electrolysis cell, permit operation at high current efficiency.  They are made by oxidation of fluorinated polymers which have pendant side chains containing sulfinic groups, or both sulfinic and sulfonyl groups.  The fluorinated polymers which have pendant side chains containing sulfinic groups, or both sulfinic and sulfonyl groups, are in turn made from fluorinated polymers which have pendant side chains con-taining sulfonyl halide groups by reduction with, for example, hydrazine.  Fluorinated ion exchange polymers which have pen-dant side chains containing -OCF2COOR groups and also pendant side chains which contain sulfonyl groups can also be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic group; and also by treatment of a polymer which contains -OCF2CF2SO3H or salts thereof with a combination of fluorine and oxygen.

Abstract: ABSTRACT OF THE DISCLOSURE      A buffer storage which stores some of blocks, into which a main storage is divided, and, when to store a new block, designates a block to be replaced based on LRU logic of designating the least recently used block as the block to be replaced.  When the buffer storage is put in a state in which the designation of the block to be replaced is not carried out, it is detected and logic different from the LRU logic is used to designate the block to be replaced, thereby to prevent that no designation of the block to be replaced is effected and consequently no block is replaced.

Abstract: ABSTRACT     An assembly for end-to-end coupling, and decoupling, of optical fibers in which the fibers are captured in a selectively expandable channel defined between a plurality of thermally actuated, shape memory vanes. The vanes are configured to provide flared ends to the channel that guide optical fibers into the channel from a precision groove in a surrounding casing. The fibers are retained within the groove of the casing by a leaf spring that prevents deflection of the fibers while holding them in place until the channel contracts around them. The thermally actuated, shape memory vanes are contained within a collar that provides a spring bias which maintains the contracted channel size at room temperature when the vanes are not thermally activated to thus securely capture and hold the optical fibers. The vanes, as an alternative, may be coated with a resilient material that adapts the channel dimensions to slightly different fiber diameters, providing exact fiber centering within the channel. The collar for the vanes is loosely fitted into a surrounding housing which limits the expansion of the channel to a predetermined size to prevent fibers from slipping out of the channel during insertion. The housing further helps to distribute the activating heat evenly around the collar, to the vanes.

Abstract: DOUBLE ACTION MANUAL CONTROL FOR     WALK-BEHIND POWER MOWER               ABSTRACT OF DISCLOSURE         A walk-behind, power lawn mower having a double action manual control requiring two distinct actions in order to start the cutting blade of the mower.  The control includes a bracket mounted to one side of the mower handle bar, the bracket having a slot with an enlarged opening therein.  A control handle con-nected to a brake-clutch mechanism is mounted with one end in the bracket slot and the other end pivotally received in the other side of the handle bar.  A spring acting through the brake-clutch mechanism biases the control handle in a raised position with one end registered with the enlarged opening in the bracket.  To start the mower cutting blade, the control handle must be rotated against the handle bar thus releasing the brake and engaging a clutch which controls the cutting blade.  However, in order to rotate the control handle, it must first be moved in one direction away from the enlarged opening in the bracket.  Then the control handle may be moved in another direction to release the cutting blade.

Abstract: ABSTRACT Apparatus for processing microwave signals at two predetermined frequencies.  Signals at a first predeter-mined frequency are received or transmitted at one end (input port) of a microwave transmission line whose other end is utilized as a common output port for transmitting and receiving signals at both predeter-mined frequencies.  A band rejection portion is provided which comprises first and second rejection resonators orthogonally disposed along the transmission line at two predetermined positions.  A bandpass portion, comprised of a plurality of collinearly aligned bandpass resonators is disposed at a third predetermined position along the transmission line. Signals at a second predetermined frequency are transmitted or received at a second input port which is part of the bandpass portion.  All resonators are capacitively coupled together and to the tranmission line.  Signals at both predetermined frequencies may be applied to the first and second input ports and are combined in the transmission line by the filtering action of the resonators.  Conversely, signals having both predetermined frequencies may be applied to the output port  and separated in the transmission line such that signals at the first predetermined frequency are provided at the first input port  and signals at the second predetermined frequency are provided at the second input port.  Also, signals at one frequency may be transmitted by way of the diplexer while signals at the second frequency are received thereby, or vice-versa.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a valve and to a process for regulating flow of particulate solids from an upstream location to a downstream location.  The valve includes an opening to the downstream location; means to provide a passage for the flow of particulate solids from the upstream location to the downstream opening; and means to seal the pressure at the upstream location from the opening to the downstream location.  The valve also includes further means to impose a non-mechanical force on particulate solids immediately upstream of the opening to the downstream location; and means to regulate the pressure imposed on the particulate solids immediately upstream of the downstream opening.         The process includes the step of sealing the pressure at the upstream location from the pressure at the downstream location; and regulating the pressure immediately upstream of the opening to the downstream location; whereby elevation of the pressure immediately upstream of the downstream location to a level above the pressure at the downstream location causes flow of particulate solids and whereby reduction of the pressure immediately upstream of the downstream opening to a level below the pressure in the downstream location decreases or interrupts flow.
