Abstract: Abstract of the Disclosure A diagnostic reagent holder specifically adapted for the detection of an unknown quantity of a biologically derived sample suitably by radioimmunoassay, fluorometric detection or by spectrophotometry.  The holder comprises an elongate shaft with a support surface adjacent one end of the shaft.  Diagnostic reagent is covalently attached to a self-supporting film such as a disc and firmly secured to the support.  The diagnostic reagent, e.g., antibody, is stirred during incubation in contact with the sample to be detected, e.g., antigen, in solution.  In a "sandwich" technique labelled substance (e.g., fluorochrome-labelled antibody) is reacted with the sample on the film followed by thorough washing.  Then, the holder is slid into a novel viewing housing which precisely positions the film at a window for viewing as with a fluorometer.  To avoid loss of labelled substance during handling, and especially during positioning in the viewing housing, one or more protective protrusions are provided around the periphery of the support surface.

Abstract: REMOVAL OF NITROGEN OXIDES FROM INDUSTRIAL GASES BY USE OF OXIDIZING SOLUTIONS IN WHICH NITRATES ARE THE                        OXIDANTS       ABSTRACT OF THE DISCLOSURE          Nitric oxide may be removed from gases which it is admixed by contacting the gases with aqueous solutions con-taining nitrate ions in sufficient concentration to oxidize the nitric oxide to nitrous acid and to retain it in the solution under stable conditions.  Other oxides of nitrogen can also be absorbed producing nitrous acid which is retained in the aqueous solution in a similar manner.  Thereafter, the scrubbing solution is regenerated under controlled conditions, producing a gas stream which contains the recovered nitrogen oxides in relatively high concentration,a scrubbing solution which can be recycled.  The recovered nitrogen oxides may be used in the manufacture of nitric acid or other compounds or decomposed into harmless gases.        The present invention relates to the removal of selected constituents from gas mixtures and, more particularly, to novel, improved methods for removing nitrogen oxides from such mixtures in order to eliminate the oxides as a source of air pollution and/or to recover the oxides for a feedstock.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus is provided for achieving true and accurate feed of linear sheet material such as a recording or plotting medium in a strip chart type utilization device, particularly in applications where a high degree of feed accuracy is required. The apparatus comprises a roller which is mounted for engagement with the recording medium as it is fed from a supply spool to a take up spool. The roller is journalled at its ends for limited universal movement. A brake pad is associated with each journalled end of the roller, the brake pads being engageable with flanges on the supply spool. If, as it is being advanced, the recording medium drifts to one side then a small amount of slack will occur at the other side. This slack is detected by the roller causing the end which senses the slack to move towards the supply spool and thereby causing the brake shoe on that side to engage the appropriate flange to correct the drift.

Abstract: WATER RECYCLING SYSTEM     Abstract of the Disclosure A closed water recycling system produces potable drinking water from total domestic waste-water, including household sewage.  A microprocessor monitors the operation of the system and automatically back-flushes the ultra-filter assembly, regenerates the ion exchange bed when the monitored variables indicate this is necessary, and acts as a failsafe monitor to insure water quality by shutting down the system in case of a malfunction.  For example, the bed includes acid and base regenerated resins having different specific gravities.  When a monitor indicates that the bed requires regeneration, a water flush separates resins by specific gravity.  Acid and base regenerating solutions are supplied to opposite sides of the bed.  The flow of regenerating solution is stopped when the salt band produced during regeneration approaches an outlet at the middle of the bed.  By stopping regeneration before excess regenerative has entered the bed, a saving in regenerating solution is effected and reduction in rinse water is effected, keeping the water losses from regeneration to a minimum.  (It is desirable to have only a small amount of by-product water of high salt content to dispose of.)  In a preferred embodiment, a rotational digestor has a wheel which evaporates the waste-water solution.

Abstract: ABSTRACT OF THE DISCLOSURE In a known type of bottle filling machine, a bottle travels on a platform which is raised so that the bottle encircles a filler tube and sealingly engages a filler bell which is slidable up and down on the filler tube.  If a bottle explodes during filling, particles of glass can adhere to the filler tube and the filler bell and it is obviously desirable to clean off these glass particles so that they cannot get into a subse-quent bottle.  However, with the presently known filler machine, when a bottle explodes the filler bell drops to the end of the filler tube and is suspended just above the platform on which a bottle rides.  This makes access to the underside of the bell difficult and hence makes it difficult to spray water to clean off the underside of the filler bell and the filler tube.  At present, it is known to have an operator manually flush the tube and bell with a low pressure water spray but this is a slow and inefficient operation.  The present invention overcomes these problems by providing a bell which has an outwardly extending flange with a radius greater than the radius of the guide surface of a bottle guide provided on the platform whereby the bell is prevented from falling to the lower end of the filler tube by engage-ment of the flange with the guide.  A plurality of spray nozzles are provided which spray cleaning llquid, e.g. water, so as to first engage the flange and push the bell up the filler tube, after which the cleaning liquid can flush the underside of the bell and the filler tube.  The spray is preferably under high pressure.  By providing the nozzles in groups, the bell is allowed to drop one or more times between groups to shake off particles and water.  An air spray may be provided after the water sprays to remove excess water.
