Abstract: Title "CODABAR" LABEL READER        Abstract of the Disclosure A method for reading bar-coded labels by taking ratios of successive bars and spaces, then discriminating and categorizing the ratios of one of four possibilities.  This output is combined and decoded into characters using a read-only-memory. The characters along with information on spacing between the characters is then passed to a microprocessor.  The microprocessor decides which of the characters are valid and assembles a complete scans worth of information by making use of the data relating to the separation between characters. Handling the data in this fashion provides a means to assemble data from partial scans of the label into one complete scan.

Abstract: ABSTRACT OF THE INVENTION   The electrodes of a electro-optic device having a flexible electrode bearing member, such as a silicon integrated circuit are re-contoured as required to generally conform to the mating surface of the electro-optic element by resiliently biasing the electrode bearing member against that surface. The bias is suitably supplied by a compressed elastomeric pressure pad which underlies the flexible electrode bearing member. The pressure pad is substantially coextensive with the electrode bearing portion of the flexible member so that a more or less uniform bias is applied throughout that area.

Abstract: ABSTRACT           LIQUID-LIQUID CONTACTING APPARATUS      The invention provides a liquid-liquid contacting process for separating a component from a mixture in which the mixture flows through or over a packed bed of strands of low surface-energy material, with gas introduced so as to flow upwardly through the bed. This gives an increased efficiency of contacting due to the hydrophobic property of the bed material and its effect on the aqueous phase and on the bubble size as the gas becomes dispersed in the organic phase.

Abstract: Abstract Mercury is removed from sulfur dioxide bearing hot and moist smelting-plant or roasting-plant gases by cooling and scrubbing the hot gases by means of a concentrated sulfuric acid mist in order to sulfate the mercury and to separate it from the gases. The cooling is carried out by vaporizing so much water or dilute sulfuric acid solution from the gases that the temperature of the gas drops to below the dew point, in order to produce a sulfuric acid mist which sulfates and washes the mercury, the gases being separated from the mist and directed to the sulfuric acid plant. The process can be carried out by means of nozzles installed in the pipe which feeds hot and moist sulfur dioxide bearing gases into the scrubbing tower of the sulfuric acid plant, water or acid obtained from the scrubbing tower being fed through the nozzles into the feed pipe in the form of a finely-divided mist.

Abstract: ABSTRACT OF THE DISCLOSURE           A magnetic disk drive has a media interchange switch which interconnects the two head/disk drive assemblies with the two electronic systems in the drive.  A manually operated switch on the operator panel operates a latching relay to one of two positions.  Multiple pole, double throw relay contacts actuated by the latching relay connect spindle and head address signals, data signals, servo signals and other signals between either of the two head/disk assemblies and either of the two electronic systems.  The sets of the switch contact poles are connected so that ground potential appears on switch contacts interposed between two active signal lines.  In this manner, shielding is obtained with relays which otherwise have such low intercontact isolation that signal interference would be present.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to telescoping handles.          Inner and outer telescoping members are provided which are rela-tively movable between a contracted position wherein there is a substantial overlap of the members and a fully extended position wherein one member extends a substantial distance beyond the other member.  A detent is carred on one of the members and spring means urges the detent into engagement with a longitudinally extending surface of the other member.  A recess is formed in the other member at a position such that in the fully extended posi-tion the detent is pressed into engagement with the recess.  The detent and the recess are configured so that extension of the members beyond the fully extended position is prevented but con-traction of the members from the fully extended position is permitted.  One of said inner member and said outer member have a portion which, between the two positions, fits closely with the other of the inner member and outer member whereby relative extension or contraction is frictionally resisted.  Between the two positions, the detent is urged into sliding contact with the longitudinally extending surface whereby relative extension or contraction of the members is further frictionally resisted.  The inner and outer members have surfaces which are circular in cross-section, and the recess extends around the entire circumference of the surfaces, so that the members can rotate indefinitely with respect to each other.  One end of the outer member is closed and the clearance between the exterior surface of the inner member and the interior surface of the outer member is sufficiently close that relative movement of the members is pneumatically resisted.
