The notches define a range of positions at which the depth adjustment arm may be positioned.

Abstract: The invention provides an apparatus and method for enabling at least a minimum pressure and flow rate of stored NH3 from a storage tank to knives for injection into soil, regardless of ambient temperature. A pressure sensor and control valve monitors the pressure of the NH3 flow. If the sensed pressure drops below a desired minimum, e.g., 0.5 psi, a controller drives the control valve to open and also signals ramping up of a boost pump. The boost pump pumps NH3 from the storage tank to ensure maintenance of a minimum flow rate and pressure of NH3 from the tank to the soil. The pump runs on-demand only as needed, thereby reducing power requirements when the pump is not needed to supplement NH3 tank pressure.

Abstract: PAW PAL: Fabric protection for paw or other extremity injuries including surgical incisions, i.e.: neuter incisions, or laceration injuries. Options include medicated pads or inserts as required. The simple yet efficient design and application results in previously unobtainable speed of healing and other recovery factors, while allowing the injured pet (or other animal) to continue his normal lifestyle, nearly unaware of the inventions application. This embodiment completely outdates previously utilized paw or other extremity injury protection methods because of its extreme simplicity and efficiency and ease of use for all involved. The use of the “Elizabethan Collar” becomes obsolete, if necessary at all. The method (Elizabethan Collar) had become the gold standard for treatment of family pets, and is surely loathed by all (including the pets prescribed the treatment) because of its inhumane and ineffective treatment of pets, for extended periods of time. PAW PAL is proven in several actual pet injuries.

Abstract: A collar useful in animal care, which includes a closure connector and a flexible belt having a free end and distal therefrom a thickened knob. Anchored within the connector's frame, the knob is disposed contiguous with a narrow slot formed therein through which all of the belt, except the knob, is initially threaded. Once looped back around the connector's frame, the free end is pushed through the frame until it re-emerges therefrom. With the collar adjusted to provide a snug fit, one can then activate a closure mechanism, in which the foot of an arm pivotally connected to the frame clamps a short portion of the belt, across its entire transverse width, against the frame. When the belt is so clamped, pulling on it increases forces pressing the foot against the belt. Cast from a silicon rubber/phosphorescent additive mixture, the belt exhibits luminescent properties, making it visible in the dark.
