A sensor probe is disclosed which can measure the hydrogen peroxide content of a single sample using two oxygen sensors whose electrodes are encased in defined membranes. The oxygen reference sensor is encased in a hydrophobic membrane which prevents the transport of hydrogen peroxide or electrochemical poisons or interferents and isolates the electrodes and an electrolyte fluid surrounding the electrodes from the sample fluid. The hydrogen-peroxide-generated oxygen (HPGO) sensor is also is encased in such a hydrophobic membrane, but has in series with and distally of the hydrophobic membrane a hydrophilic membrane which contains an immobilized enzyme such as catalase, peroxidase or other enzymes of a family which catalyzes the reaction of hydrogen peroxide to oxygen and water. At the HPGO sensor, the hydrogen peroxide is catalyzed to oxygen by the enzyme so that the HPGO sensor measures an enhanced concentration of oxygen relative to the oxygen reference sensor. The signals of each of the oxygen sensors are sent to a summer, which subtracts the equal background oxygen concentration of both, yielding a resultant difference signal representative of the concentration of hydrogen peroxide content of the sample itself. A suitable display or data collection device is used to capture the information in visible or digital form. Methods of use of the device for determining hydrogen peroxide content of human or animal tissues or fluids, or environmental or industrial fluids or fluid-containing materials, are also disclosed.

A warehouse stacker crane for inserting and removing a load in a storage station of a storage rack including a chassis movable horizontally along an aisle adjacent the storage rack, a carriage on the chassis which is movable vertically to a position aligned with the storage station, and load-grasping apparatus on the carriage for releasably grasping the load and for inserting and removing it from the storage station. The load grasping apparatus comprises a horizontally disposed rotatable splined shaft on which a pair of arms is mounted. The arms have load-engaging devices at their distal ends. The arms are swingable in horizontally spaced apart parallel vertical planes 15 as the shaft is selectively rotated. The arms are also slidably movable axially on the shaft toward and away from each other to grasp and release the load by a selectively operable actuator connected therebetween. Prior to load insertion and removal the arms are drawn toward each other to engage the load. During load 20 insertion and removal the carriage is moved vertically simultaneously with the arms (with load attached) being pivoted. As a result, the load moves only horizontally relative to the storage station. After load insertion, the carriage is lowered slightly to place the load in an at-rest position in the storage station. Prior to load removal, the carriage is raised slightly to raise the load from the at-rest position. A control system operates the stacker crane and the load-grasping apparatus.

The storage and retrieval apparatus of this invention comprises parallel tracks, each normally supporting numerous upright storage bins that are in close proximity to one another and to bins on laterally adjacent tracks. Each bin is open at its front and is mounted on wheels to roll rearward along its track. An overhead carrier lifts a desired bin off its track to a level above the other bins and carries it forward. A pusher near the front end of that track pushes rearward on the front bin, moving bins back to fill the space left by the lifted bin, which is then lowered into the space at the front of the track for loading or unloading, through its open front. On the top of each bin is an identifier plate distinctive to the bin. A sensor on the overhead carrier, connected with a computer, reads the identifier plates as the carriage moves rearward along a track and is thus able to find and lift a desired bin even though it is in a random position along the track. Gates at the front of the tracks are arranged to prevent personnel from getting in the way of bins being lowered.

On a truck comprising tandem flangeless wheels riding on a single rail and four guide rollers rotatable on vertical axes, two at each side of the rail, crabbing and turning misalignments of the wheels are diagnosed from information about which rollers rotate during truck movement in each direction along the rail. For obtaining that information, a small reflective spot is delineated at an eccentric location on the upper surface of each roller, and a photoelectric sensor for each roller, magnetically attached to the truck, has its optical axis aimed at the orbit of the spot to issue an electrical impulse for each roller rotation. A signal device connected to each sensor issues a perceptible signal for each impulse. The signal devices are at a single console to facilitate comparisons of the number of revolutions made by the several rollers during a truck movement.
