Abstract: METHOD AND SYSTEM FOR AUTOMATICALLY DETECTING               CAMERA PICTURE ELEMENT FAILURE     Abstract of the Disclosure A system and method are disclosed for detecting picture element failures in a multielement array.  In a pre-ferred embodiment of the invention the illumination of a reference background by a lamp is controlled by a controlled power supply to be off in a first mode of operation and on in a second mode.  During a diagnostic operation, the refer-ence background is scanned by a N element CCD array to provide N reference pixels for each scan during each of the first and second modes of operation.  During the first mode, a first error signal is developed for each of the N reference pixels in a first mode scan that is greater than a first signal level.  During the second mode, a second error signal is developed for each of N reference pixels in a second mode scan that is less than a second reference level.  These first and second signals are then respectively utilized by a first counter to store the total number of pixel errors detected in a first preselected scan during the first mode and a second counter to store the total number of pixel errors detected in a second preselected scan during the second mode.  The counts of these first and second counters are then utilized in conjunction with address and control signals to selectively store in associated first and second circuits the associated numbers or addresses of the defec-tive elements in the array for each of the first and second modes of operation.

Abstract: ABSTRACT            The present invention relates to a labelling machine for bottles (1) to which one or more labels are to be applied, aligned according to a specific marking (29) on the bottles (1).     Prior to application of the first label the bottle (1) locked between a rotor (13) and a rotor head is scanned with reference to the marking (29) and rotated to a desired orientation by means of an electric motor (27).  The rotational movement of the motor (27) is introduced through one input of a differential gearing (18, 21, 23), whereas the rotational movement needed according to a fixed program prescribed for the labelling process is introduced through the other input of the differential gearing (18, 21, 23).  In this manner it is possible to bring the bottle to the required rota-tional position without releasing and regripping them between the rotor (13) and the rotor head.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to an improved valve bag placing machine and method.  The valve bag placing machine according to this invention is adapted to remove a valve type bag from a stack on an indexing conveyor, open the valve opening thereof, and insert this opening over a material dispensing nozzle of a bag filling machine.  Vacuum cups, movable in response to actuation of pneumatic cylinders, contacts the valve bag at the end flap and side portions thereof.  As these cylinders are retracted, a valve opening rod contacts the side of the bag to positively strip away the valve end flap from the side of the valve bag.          Once in this position, one of the vacuum cups is removed from the bag and the valve bag clamping assembly is rotated by an actuator assembly.          Prior to, after, or simultaneous with this rotation step, another pair of vacuum cups contacts the side of the valve bag and pulls it down with respect to the valve bag end flap, thus opening the valve bag valve opening.  Once the valve opening is presented, the valve bag clamping assembly is caused to translate linearly  such that the valve bag surrounds a material dispensing spout of the bag filling machine.  At this point, vacuum to the various vacuum cups is relieved and the valve bag clamping assembly is returned to its initial position in registry with a valve bag on the indexing conveyor.

Abstract: ABSTRACT     An enzymatic assay and a kit to detect rapidly beta lactam antibiotics in a liquid sample such as milk are shown.  In the assay a reaction medium is formed by adding a liquid sample (e.g. raw milk) to a predetermined amount of a combination of dry reagents comprising D,D-carboxy-petidase, a substrate for D,D-carboxypeptidase containing a carboxy terminal D-alanine, and a reagent system which produces a color reaction in the presence of D-alanine. Second, the reaction medium is incubated at a temperature between 20° to 60°C for a predetermined period of time. Thereafter a material which quenches the color forming reaction is added and the color of the reaction medium is examined.  That color can be correlated to the color intensity found with known amounts of antibiotic.  The preferred reagent system which results in a color reaction in the presence of D-alanine comprises a D-amino acid oxidase, a cofactor for D-amino acid oxidase, perioxidase and an organic redox indicator, e.g. o-dianisidine, which undergoes a color change when oxidized.

Abstract: GAS PURIFIER FOR RARE-GAS FLUORIDE LASERS                Abstract of the Disclosure A closed-cycle gas scrubbing or purification system is described for noble gas and fluorine mixtures, such as are typically used in rare-gas fluoride (excimer) lasers.  In a first reaction zone, the fluorine in the gas mixture is converted to titanium tetrafluoride vapor by reaction with titanium at a temperature above 150 degrees C., preferably at about 300 degrees C.  The TiF4 vapor is then removed without passivating the titanium by condensing the TiF4 vapor in a separate condensation zone held at a temperature below the temperature of the first reaction zone, preferably at about room temperature. After condensing the TiF4 from the gas mixture, any silicon tetrafluoride in the mixture is chemically removed by contacting the gas mixture with an alkaline earth oxide (preferably either CaO or MgO) in a second reaction zone.  Residual contaminants (i.e., contaminants other than SiF4) are removed from the gas mixture by contacting the gas mixture with a metal getter (preferably titanium or zirconium) at a temperature above 600 degrees C., preferably about 900 degrees C. or more.  The hot metal gettering preferably is done in the second reaction zone by mixing or layering the metal getter with the alkaline earth oxide and heating the second reaction zone to a temperature above 600 degrees C. Fresh halogen gas is added to the purified rare-gas mixture before it goes back to the laser.  Since SiF4 is specifically removed, it is acceptable to use industrial grade titanium to remove the fluorine and as a hot metal getter for residual contaminants.
