Abstract: An audible warning system which reduces the number of land vehicle traffic accidents where there are already traffic control devices installed such as at stop signs, intersection control lights and on vehicles in conjunction with side lights, tail lights and brake lights. The accident reduction results from the monitoring of approaching traffic with a radar-type range sensing system. Sound generators, based on parametric-array technology, permit the focusing of sound into waves of a few degrees width and aiming them at a particular vehicle or pedestrian located at a particular range from the sound projector.

Abstract: A non-lethal method and devices for dispersing nuisance birds from a preselected area. Such nuisance birds disrupt many activities such as the steady flow of safely moving aircraft on runways and adjacent thereto, growing crops on farm land, playing golf and the use of the interior of large open buildings. The present method utilizes a series of bright light sources which are positioned adjacent the area from which the birds are to be dispersed. The light sources are activated to produce one or more beams of bright light which are moved in such a manner to produce a pattern of bright light in the vicinity of the birds to be dispersed. This action causes the birds to become sufficiently startled and disoriented so as to disperse these nuisance birds from the area to be cleared.

Abstract: A conveying system having a plurality of rotating rollers forming a horizontal drive path for moving articles and at least one pop-up stop for stopping movement of articles in such path. A pair of levers are mounted for rotation about a pivot to move one lever arm of each of the pair of levers above and below the horizontal path and thus move one of the rollers above the path in a position to stop articles on the conveyor. There is a pair of rollers mounted for rotation in the horizontal path on one lever arm of each of pair of levers. A pneumatic actuator is connected to at least one of the levers for moving the pair of levers about the pivot thereby to move one of the rollers to a position above the horizontal path.

Abstract: Supercritical and near critical fluids are used to fractionate biomass materials such as microbial cells in two steps. In the first step, the biomass is exposed to elevated pressure supercritical or near critical fluid to bring about disruption of the biomass to liberate structural biomass constituents. In the second step, the disrupted biomass is subjected to a multiplicity of supercritical or near critical fluid extraction steps, with different solvation conditions used for each fraction. Thus, fractionation of the biomass to obtain one or more compounds is effected. Different solvation properties are obtained using different temperatures, pressures and/or modifier concentrations.

Abstract: A diverter for a conveying system which includes a belt conveyor moving along a longitudinal conveying path for transporting flat articles, including a longitudinal conveying path which includes a series of moving belts for moving flat articles therealong. There is a bin for collecting diverted flat articles. A hinged diverter gate is provided above or just forward of the bin for providing a diverting surface of moving belts which, in a first position, allows flat articles to move therealong, and, in a second position, allows the flat articles to move into the bin into which the flat articles are diverted. The bin is located beneath the conveying path and the articles are moved into the bin by the moving belts when the diverter is in its second position. The gate is hinged at a point which is different than the axis of the drive rollers so that the movement of the belts assists the upward movement of the gate when a flat article is to be diverted into the bin below.

Abstract: A method and means of dispensing T-shirt type plastic bags from a rack mounted beneath a counter from a tray which slides horizontally into an existing industry standard rack which interlocks with the rack but when needed for loading, can be pulled forward, tilted downward, and loaded with bags and slid back into the rack, where it will align, hold and dispense bags. Optionally, a new frame can be mounted under the counter and a second tray (similar to the first tray) is held within the same frame so that it can hold two different size bags, allowing one frame to dispense two different size bags. Alternatively, a frame can be made to hold only one tray if space is limited. In all three forms the horizontal tray slides forward and tilts downward to receive pads of plastic bags. Only the T-shirt handles and the upper half of the bags are contained within the frame or rack. The lower half of the bags drape over and downward from the front of the rack.

Abstract: A pressure operated normally closed control valve operates to open at a predetermined pressure between the system minimum and maximum pressures to open the valve and allow the discharge of condensate from the system which has a source of pressure to provide a minimum and a maximum pressure. The system is subject to the formation of condensate. There is an inline filter at the inlet end of the valve and a discharge nozzle at the outlet end of the valve. The entrance to the discharge nozzle may also have a filter. The assembly can also be arranged so that the control valve is normally open and operates to open at a predetermined pressure at or below the system minimum pressure whereby condensate is removed, and to close the valve and prevent the discharge of condensate from the system when the pressure falls below the predetermined pressure.

The instrument can also be used with a plate for cone plate, oscillation and normal force measurements.

Abstract: A lighting assembly which includes light source means and collimating means for substantially collimating the light from the source. There are transmission means for transmitting the substantially collimated light to a point remote from the collimating means, and, in one arrangement, having an upper section which allows transmission of light therethrough and a lower section which reflects light. Light direction modifying means such as a lens or a reflector is located in the transmission means and remote from the collimating means for receiving light from the collimating means and modifying the direction of the light to pass outside of the transmission means through the light-transmitting section. The light direction modifying means includes a large plurality of prisms on the outer surface thereof. The prisms may be arranged so that the radii of several adjacent ones substantially meet at a point, thereby to form a “wave” lens.
