Method and Apparatus for injection steam of know quality into a subterranean reservoir containing hydrocarbon fluids, to enhance or stimulate production of said fluids through a production well. Production stimulating steam from a pressurized source is injected into the reservoir by way of a critical flow venturi and an injection well, in a manner to maintain the steam at a desired pressure and flow rate. The venturi's constricted throat is formed as a function of the stimulating steam's original characteristics.

A blower centered on the axis of a combine immediately to the rear of the seive that carries the majority of the chaff for discharge onto the ground has a bilateral air nozzle that directs high velocity air perpendicular to the axis of the combine to cause the chaff to be spread across a substantial width distance at the rear of the combine. The spreading reduces concentration of such chaff in a narrow path and spreads it fairly evenly on the ground. The spreading reduces or eliminates problems encountered in minimal till or no-till planting that can be caused by having a deep layer of chaff that is toxic to successive crops that are planted without tillage. Any volunteer plants emerging from a chaff row cause competition for the planted crop and reduces yields.

An apparatus is provided for filling the wells of an antibiotic plate with different concentrations of fluid including an array of fluid containers, each having a single needle valve inserted through a stopper member which is held in an open end of the container. Each needle valve includes an inner tube for supplying pressurizing air to one end of the containers which forces the fluid through an outer tube of the needle valve and out the opposite end of the container. A length of flexible tubing connected to each of the needle valve outer tubes carries the fluid through one of a plurality of slots formed in a pinch valve assembly. The pinch valve assembly includes slide members and resilient pinch rods extending laterally from sides thereof. In a first position, the slide members are held such that the pinch rods close the flexible tubing to prevent passage of the fluid into the wells of the antibiotic plate. In a second position, the slide members are held such that the pinch rods do not closably engage the tubing but permit the passage of fluid into the wells. The resiliency of the pinch rods minimizes the criticality of providing lengths of flexible tubing having the same cross-sectional size to assure proper opening and closing of the tubing.

Microplate filler

A self feeding bunk or barrier used for permitting cattle to eat directly from stacks of forage such as hay, and which comprises a modular member having an upright, slat barrier through which the animals can feed from a forage stack that the sections surround. The barrier modules include a horizontal support deck attached to the upright barrier and held by end frames. The horizontal floor or deck is of sufficient lateral width (outwardly from the stack) so that the animal which is feeding cannot reach through the upright barrier for eating unless it is standing on the deck. The barrier module is securely held by the animal itself as it eats so that the barrier cannot be dislodged.

A depth control for grain drills, planters or the like utilizing a press wheel which can be adjusted to control the depth of each individual furrow opener to insure uniform depth of planting across the width of wide machines presently in use.

A motor driven inoculator is provided wherein a plurality of bacteriological transfer loops are mounted on a common head and are activated in response to the positioning of a tray of inoculum to cause the head to be lowered and then raised so that the loops pick up a sample of inoculum. The subsequent positioning of an antibiotic or antimicrobic microtube plate, etc. causes the head to be lowered and raised a second time so that the loops are lowered into the plate to place samples of inoculum in each of a plurality of wells in the plate by dispersion. The removal of the antibiotic plate initiates a sterilizing cycle wherein the head is lowered and raised a third time whereby the loops are heated to a very high temperature by passing electrical current therethrough to volatilize all material thereon and then they are subsequently air cooled prior to the beginning of the next cycle. In an alternative embodiment the inoculum on the loops may be dispersed by percussion. The inoculum tray includes a plurality of grooves and ridges so that a minimal amount of inoculum is necessary for use in placing samples on the loops by dipping.

Inoculator

A feeding control for regulating the feeding of hay or other forage crops into a grinder of the 'tub' type wherein a large hopper or tub is used for feeding the forage into a rotating cylinder adjacent the bottom of the tub, and wherein the forage or hay crop is moved across the cylinder for grinding. The feed control comprises a slidable cover plate member that regulates the size of the effective inlet opening to the cylinder to control the amount of forage which can contact the cylinder at any one time.
