Abstract: Medical solution is passed in a conduit across a solid, microcrystalline mass of beneficial agent to cause the beneficial agent to dissolve in the medical solution. The beneficial agent comprises a mass of citrate or mannitol in a substantially anhydrous form, the mass being shaped and proportioned 80 that a controlled amount of the beneficial agent dissolves into passing medical solution in a manner that is substantially predetermined. For example, the beneficial agent can dissolve in substantially uniform manner, whereby no substantial portion of the medical solution, such as blood or another parenteral solution, is exposed at a relatively constant flow to a significantly higher concentration of the beneficial agent than other flowing portions of the medical solution. The citrate or mannitol mass of the beneficial agent may include at least one added effective agent for dissolving in the medical solution as the citrate or mannitol dissolves therein.

Abstract: Methods and apparatus for use in quantifying components in a liquid sample, for example, white blood cells in blood.  The invention provides a microscope slide for such use having at least one adhesive matrix, which is soluble in the liquid sample having components to be quantified, affixed to the operative face of the slide, and a plurality of substantially spherical beads of uniform diameter made of a substantially non-compressible material located within the adhesive matrix.  A counting chamber is provided when a cover slip is provided with the slide.  The invention further provides a stirring rod for use in quantifying components in a liquid sample having an adhesive matrix over one end portion, the adhesive matrix being analogous to the adhesive matrix on the microscope slide described above.  The adhesive matrix or matrix can consist of a solid residue of dried liquid, and the liquid can be a hemolysing solution if the equipment is to be used for counting white blood cells.  A standard microscope slide is provided by the invention when the adhesive matrix made of a solid residue of dried hemolysing solution, also contains a known number of control particles, treated so as not to lyse in the presence of the hemolysing solution and shaped and sized so as to simulate human white blood cells.  Methods for preparing this apparatus, using mixtures of adhesive liquids and beads, are also provided.  Furthermore, methods of quantifying components in liquid samples using the apparatus described above are provided.  Generally, the methods consist of either placing a liquid sample on the adhesive matrix of the microscope slide and mixing it so that the matrix dissolves in the sample, or placing a liquid sample on an unprepared microscope slide and stirring it with the stirring rod having the adhesive matrix over one tip so that at least a portion of the adhesive matrix dissolves therein.  A cover slip is then placed over the sample so that the cover slip rests on the beads and is spaced from the slide by a known distance determined by the diameter of the beads.  The counting chamber provided thereby is placed under a microscope and the components in a known volume of sample are counted, wherein the known volume is determined by measuring the viewing area of the microscope and multiplying the viewing area by the distance between the slide and cover slip as determined by the diameter of the beads.

Abstract: ABSTRACT      A reading circuit for an optical recording medium having a clock track having a predetermined optical pattern formed along data tracks and comprising at least one irregular clock bit disposed in a line formed of regular and periodi-cal clock bits, breaking the regularity of the periodically arranged clock bits, which circuit comprises: a phase locked loop (PLL) circuit receiving read clocks obtained by reading the clock track; and an irregular clock detecting means comparing a clock output from the PLL circuit and the read signal and generating a detection pulse when it detects the irregular clock bit which breaks the regularity of the periodically arranged clock bits.  According to the present invention, when the PLL circuit is reinstated into the locked position after the PLL circuit has fallen into the out-of-locked position, a leading word can be identified by the irregular clock bit provided in the clock track.  There-fore, the read data thereafter can be recognized accurately. This can be attained without lowering the recording capacity of the optical recording medium.

The web of sleeving  material        is  supported  for  movement  in  a direction perpendicular to the rows of pockets       by a chassis base     .  A slide shuttle      removes photograph slides     from a hopper     and moves the slides to a first position     on a slide support          .  Photograph slides at the first position       are moved to second and subsequent positions            in a row corresponding to positions of the pockets in the row of slide sleeving material .  A slide counting mechanism       mechanically counts the photograph slides      moved to the positions         on the slide support         .  Pocket opening means      such as coil springs       arc the slide sleeving material      to open the pockets      of the row into which the photograph slides       are to be inserted.   A slide pusher       is actuated when the predetermined number of slides      have been positioned on the support means        , and push the slides      into the corresponding pockets      of the row of sleeving material      during a first stroke portion.  During a second stroke portion the sleeved row of photograph slides and sleeving material      are pushed beyond the pocket opening means      by the row spacing distance so as to align a next-adjacent row of pockets      with the pocket opening means and slide support          .  A sleeve clamp clamps the sleeving material      with respect to the chassis base      during the first stroke portion, and releases the sleeving material during the second stroke portion.
