Abstract: Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine. Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.

Abstract: A portable arrangement to allow a user to retrieve and then later refile a single sheet of single or multi-part architectural plans, blueprints, and/or any document from a flat storage file drawer. The portable arrangement allows the removal of a single sheet from a tightly packed stack of sheets without losing the place of the single sheet in the file and to replace the single sheet in the stack of sheets without disturbing the order in which the sheets are arranged. A first embodiment comprises an upright rack having opposite feet that are interconnected by a crossbar, a sheet separator, first clamping device, and second clamping device, said sheet separator having a tapered front portion and a device for being mounted on at least one transverse member which in turn has a device for slidingly coupling to runners of the storage drawer.

Abstract: A prefabricated building structure having a truncated, cone-like sidewall structure fabricated from a plurality of conjoined, arcuate surface sidewall panels with adjacent panels being interconnected by an external interruptible means. The sidewall panels, mounted on corresponding flooring panels, separately support conjoined ceiling panels which are of a wedge-shaped planar configuration and have a truncated inner end flanged upwardly for locking engagement with a central closure means. Various selectable insert panels or modules are engageable within the sidewall panels to provide a structure adapted to a variety of utilities including, but not limited to, housing and storage.

Abstract: A vehicle engine speed controller for automatically determining the electrical load demand made of the engine electrical system from portable auxiliary and vehicle mounted electrically operated or controlled equipment, singly or in combination, and controlling the engine throttle speed setting through a governor with certain fail safe control mechanisms.

Abstract: Apparatus and method for the forming of fiber structures or webs utilizing a rotor having a plurality of blade sets helically arranged about its periphery for detangling and declumping air-entrained fibers which are deposited against a sizing screen, said blades act to push individualized fibers, with the assistance of positive air pressure, through the screen into a free-fall zone for deposit on an underlying forming wire.

Abstract: An improved multiple stream, fluid mixing and dispensing apparatus for automatically regulating flow rate for one or more preset fluid flows including a plural station, fluid flow rate console assembly adapted for cooperating with the standing hydraulic pressure of a dual fluid supply means with a variable effluent flow rate regulator interposed in each of the main supply conduits and associated controller means for presetting the flow rate through each regulator and for determining both the degree of mixing and the incidence of fluid flow to be provided from each supply conduit to the exit conduit. The apparatus being specially adaped for permitting pneumatic operation.

Abstract: A tri-modal filter canister adapted to contemporaneously remove both entrained water and suspended solid particles from non-aqueous fluids, said water and particulate removal functions being separate and substantially severable within said filter canister.

Abstract: A multipurpose template for folding oversized variable linear dimensioned documents, prints or plans adapted to fit over a vertical support surface, such as a room or closet door, which provides two perpendicularly oriented alignment elements fixedly secured to a planar folding surface. The alignment elements display fold line locating indices and sets of graphic pattern folding instructions for folding said oversized documents to a size suitable for mailing or storage with the resulting folded document displaying the legend or title block on the upward facing plate or segment of the folded document. The template also provides a surface for temporary writing with erasable marker, a screen for viewing projected images, and a guide for cutting and trimming such oversized documents.

Abstract: A screen or grid adapted to be placed in close proximity to the receiving end of a trash receptacle housed within an enclosure which permits smaller dimensioned trash to pass through openings in the screen or grid but will prevent larger dimensioned reusable objects, such as food carrying trays, from being mistakenly or inadvertently disposed in the trash receptacle.

Abstract: An improved multiple stream, fluid mixing and dispensing apparatus for automatically regulating flow rate and temperature for one or more preset fluid flows for connection to domestic water delivery systems including a plural station, fluid flow rate and temperature control console adapted for cooperating with the standing hydraulic pressure of a dual temperature fluid supply means with a variable effluent flow rate regulator interposed in each of the main supply conduits and associated controller means for presetting the flow rate through each regulator and determining both the degree of mixing and the incidence of fluid flow to be provided from each supply conduit to the exit conduit.

Abstract: An apparatus for achieving the effect of air movement in instruments during replication and sounding of complex musical instruments by separating unstable frequency components, the quasi-periodic components, from stable fundamental and harmonic components, the periodic components, of compound voice waveforms, storing the respective component information pertaining to the quasi-periodic and periodic components in separate memory locations, and recombining the quasi-periodic component with one or more periodic components in appropriate fashion to form and sound the compound voice waveforms.

Abstract: The computerized car wash controls a plurality of washing and waxing devices for cars. These devices are controlled by command signals and the cars are moved through the devices via a conveyor. The system includes a car tracking scheme that monitors the position of the cars as they move by the plurality of car washing and waxing devices. The system also includes an input device at which the car wash operator selects certain car washing and waxing options as ordered by the car owner. The system includes a device for generating command signals for each of the plurality of car washing and waxing devices. The command signal generator generates these signals based upon (1) the selections obtained by the car wash operator at the input device; (2) a pre-established baseline operational sequence for the plurality of car washing and waxing devices; and (3) the positions of the cars that are determined by the car tracker.
