Abstract: A hybrid binder-folder utilizing a foldable ring system for holding pages, which affords the advantage of easy page manipulation of ring binders with the advantage of flat folding of folders. The binder-folder has two side members which are mutually foldable along the centerline therebetween. Two, three or more foldable rings of flat, thin cross-section and of substantially semicircular shape are connected with the side members adjacent with and transverse to the centerline. When the two side members are mutually folded closed, the foldable rings fold along three folds: adjacent each connection with the two side members and at the ring apex. As a result of this foldability feature, the foldable rings are able to flatly fold, thereby permitting the binder-folder to be substantially flat when closed.

Abstract: A bonsai training planter structured in the form of a screen walled plant container covered with a sheet material having a preselected opacity. It is preferred that the corners thereof be provided with structural members to which screening is attached. The mesh size of the screening is small enough to hold soil placed within the planter, but large enough to permit roots to grow therethrough. The sheet material is placed over the screening in order to provide a low light environment at and near the screening which is conducive to auxin production. In operation, a seed or seedling is placed in the soil of the bonsai training planter. As dominant roots grow, they reach the screening and then commence to emerge therefrom into air. The portions of the dominant root emerging from the screening dry-out and die. The death of the emergent portion of the dominant root send auxins up the root, thereby inducing feeder root growth along the dominant root.

Abstract: An electro-optical control system having a multi-key keypad, an alpha-numeric display, means for periodically generating a pulsed light beam, means for detecting a portion of the light beam to generate an analog signal, means for converting the analog signal to a digital signal and means for subtracting an ambient light level form the digital data to generate a difference signal. The difference signal is averaged and filtered to generate a digital signal level which is displayed on the alpha-numeric display. The electro-optical control system has two output switches which are activated when digital signal level is between programmed upper and lower limits for each output switch. The values of the upper and lower limits are programmable using the keypad. The upper and lower limits are displayed on the alpha-numeric display as they are generated.

The handle component includes an operator handle and a head connected with one end of the handle. The actuator component includes a main body which removably connects with the head and contains a power drive unit which reciprocably moves a T-bar in response to selective pressing of push button controls. Pivotally connected with the T-bar are a pair links which are in turn pivotally connected, respectively, with the near end of a pair of arms. The pair of arms are connected pivotally to the main body. The distal end of the pair of arms is provided with claws for gripping the wings of a spring tension clamp. The pair of links operate in combination with the pair of arms so as to provide a high mechanical advantage due to the scissor-like operation thereof.

Abstract: A combustion box exhaust filtration system and method which removes both particulate matter (PM) and unburned hydrocarbons (UHC) from the exhaust gases. Two filters in parallel are used, each alternating operation as the other regenerates. Each filter is preferred to be constructed in a conventional manner and operates at between 100 to 300 degrees Centigrade. A microprocessor controlled valve system regulates which filter is active and which is regenerating and/or inactive. PM accumulates at the active filter, with UHC condensing on the PM. Accordingly, only PM and UHC free gasses pass out the exhaust. When the active filter becomes clogged, the microprocessor switches it to inactive status, and switches the other filter to active status. Regeneration of the inactive filter is initiated by the microprocessor using a glow plug at a predetermined location in the filter, in which PM and UHC burn slowly across the entire filter.
