Mixed culture interactions can be studied by providing a fluid tight housing defining a central diffusion reservoir for carrying a liquid culture nutrient medium. The housing is provided with a plurality of discrete radially extending organism growth chambers for culturing organisms in the liquid culture nutrient medium. Each organism growth chamber communicates with the central diffusion reservoir and each organism growth chamber is radially spaced on the periphery of the central diffusion rese...

A hand tool for different sized tools such as Allen head drivers which allows for a selection of the required size on a single tool handle. The cylindrical handle is provided with a central axial socket member mounted in a central axial opening. The socket member has a hexagonal axial opening at the bottom end. A pivot ring is mounted over the bottom edge of the socket member and a plurality of pivot members are mounted on the ring. Each pivot member supports a sleeve holder in which a hexagonal...

A device comprising a rotatable print cylinder having rows of raised symbols disposed about its periphery in arcuate columns and an impactor assembly having ballistic elements cooperating with each row of raised symbols for columnar printing of selected symbols in rows on an endless web of multiple sheet ticket stock. The sheets are bound at selected intervals and are formed with sprocket holes disposed in spaced parallel relationship with the longitudinal axis at the margins thereof. The ticket...

A control system for synchronizing the rotation of the recording discs of a plurality of disc drives so that the read/write heads of all of the drives will be at the same relative position on the rotating discs thereby reducing the latentcy time in switching between disc drives.

A multiple dose paste dispenser in which the amount of the paste formulation which is dispensed is controlled by an adjustable stop means in the trigger housing of the dispenser.

A pump having multiple cylinders radiating from a common intake cavity, receiving respective pistons driven by a central, eccentric cam, and connected to a common outlet manifold by respective outlet conduits is provided with a check valve assembly in the manifold in which circumferentially spaced guide pins are fixedly fastened to a common connecting ring, and each pair of circumferentially adjacent pins guides a valve plate for free movement toward and away from the orifice of an associated ou...

An animal feeder which includes a plurality of compartments each adapted to receive a quantity of animal feed therein, the compartments being aligned and having a bottom door which opens to dispense the animal feed. A common timer mechanism is used for all of the compartments wherein a motor through an appropriate gear box rotates an elongate shaft. The shaft has a cam adjacent to each compartment. The cams are adjusted relative to one another to move to an operative position forcing open the do...

A multiple-lock securing system for providing access to a secured area by releasing one of the locks. A bar has a security device attached thereto. A locking plate contains openings with locks positioned therein. The bar can be fastened to the locking plate when the locks are positioned in each of the openings. When one of the locks is removed from the locking plate, the bar is released providing access to the secured area.

Apparatus disclosed herein provide simple means for observing chemiluminescent reactions and for measuring the concentrations of several constituents of a gaseous sample substantially simultaneously, as for example the concentrations of NO.sub.x, NO and NO.sub.2 in a mixture of other gases. Chemiluminescence is induced by the spontaneous reaction of selected constituents with reagents in a plurality of small reaction chambers confronting a single sensitive photodetector. The reaction chambers ut...
