This safely suspends the now covered pole saw while climbing aloft in a tree.

Abstract: Apparatus, methods, and systems for useful sampling of seed, wherein viability is maintained, are disclosed. Seed from one generation in a plant advancement experiment is individually sampled by removal and collection of tissue from the seed using a hand-held and manually operated tool having one or more cutting edges. The tissue is then processed to derive one or more biochemical, genetic, or phenotypic characteristic of the seed before a decision is made whether to utilize that seed further in a plant advancement experiment or other plant research and development. In some embodiments of the method, the sampling is controlled to remove a useful amount of tissue for analytical purposes without significant effect on viability potential of the sampled seed. In some embodiments, the sampling is controlled to deter contamination of the sample. In some embodiments, the seed is held in pre-determined orientation to facilitate efficient and accurate sampling.

Abstract: Signal coupling systems are provided which enhance signal isolation and dynamic range with structures that increase bias voltages in upstream signal amplifiers to guard against transistor saturation that would otherwise increase current drain, reduce response time and possibly cause lock-up of an associated gain-control system. Dynamic range is thus enhanced because these systems can operate over an extended range of source signals. The increased bias voltages also decrease parasitic junction capacitances which increases input impedances and thereby enhances signal isolation and reduces signal distortion.

Abstract: This invention is a knife block for storing cutlery that can be locked to prevent the removal of the knives. An adjustable cap piece rests in one of two positions. In the unlocked position, the cap fits snugly over the base and the knives project up through holes in the cap.

Abstract: Scissors for angularly cutting sheet stock is disclosed. The scissors comprises oblique slots in a lower handle, fasteners in the oblique slots, a rear elongate slot in a lower ridge of a board, and a pin slidably defined in the elongate slot. In a closed state, fasteners are slid to a lowest point in the oblique slot to be urged by the ridge so that the ridge is prevented from further rearward movement with energy stored in a resilient piece. In a cutting operation press the lower and the upper handles against each other for causing the board and the blade to close on the sheet stock. The ridge pivots in response to pivoting the lower handle. Pin slides along the elongate slot to move the ridge. A rear portion of the board moves upward. A pointed end of the blade closes on a forward end of the board.

Abstract: A transparent plastic shield kit for hand-held weed trimmers of various designs is disclosed. The kit includes a substantially square, transparent, planar shield with a vertical U-shaped slot that divides its upper half in equal parts.

Abstract: A cutting apparatus has been produced that eliminates the common occurrence of raw razor blades contaminating everything from food and food products to garbage cans to shelves in retail stores. Furthermore, the cutting apparatus comprises a guard assembly that, when activated, opens the blade cover and allows only one cut to be made with the exposed blade before the unidirectionally-locking blade cover snaps back over the exposed blade, thus preventing laceration-related accidents. In addition, if the operator continues to activate the guard assembly (squeezing, pulling and/or depressing the trigger and/or releasing the trigger and continuing to hold it in the released position during and after the cut has been made) after one cut has been made with the exposed blade, the unidirectionally-locking blade cover will still snap back over the exposed blade, despite the position of the trigger.

Abstract: A cutting device provides for hands free cutting of a material such as thread, string, line, filament and rope. The cutting device is generally an L-shaped device, which includes a blade contained within a housing that is connected to a back support at an angle, which provides sufficient clearance for material to be inserted into a slot within the housing and cut against a cutting edge of the blade. The back support is provided with an attachment means for attaching the back support to a fixed object thereby facilitating hands-free cutting.

Abstract: The present invention has a safety hood which is pivotally mounted to the body of the knife at the front end. The body is pivotally mounted to a spine at the back end. The blade is removably mounted on the spine such that the hood covers the blade when the knife is closed. The hood is biased closed and has a latch to hold it closed unless the latch is released. The user depresses a button, which moves the latch, releasing the hood to push up when the user presses the hood against a working surface. The hood's rotation, and therefore the about of blade exposed, is controlled by an adjustable depth assembly. The adjustable depth assembly has multiple settings, allowing the user to control the cutting depth of the knife.

Abstract: A transparent plastic shield kit for hand-held weed trimmers of various designs is disclosed. The kit includes a substantially square, transparent, planar shield with a vertical U-shaped slot that divides its upper half in equal parts.
