Abstract: This invention relates to a hook-shaped hanger adapted to be attached by a pair of spaced prongs to a vertical panel wall and adapted to support an envelope of plastic film that hangs form that hook-shaped hanger to serve as a temporary file repository for a user. The hook-shaped hanger includes a ridge across the outside surface of the hook that retains the envelope on the hook when a file or the like is being removed from the envelope. The envelope may be a single file envelope supported by a single hanger or a multifile expandable envelope supported by two spaced hangers.

Abstract: An enclosed drainage facility to dry municipal waste combustion ash has a plurality of spaced elongated channels to drain by gravity, water from piles of ash into a disposal or reclamation pool. The channels are sloping concrete ditches leading to a common trough or pipe to a covered storage basin. Steel plates pierced with a plurality of spaced slender slits abut each other to cover each channel. The atmosphere in the facility is changed by being pumped into one side of the facility and exhausted adjacent an opposite side. Also, a process for drying municipal waste combustion ash includes dewatering and drying of ash piles in an atmosphere of warm dry air for a period of time necessary to reduce the moisture to about 28%.

Abstract: A self-locking core and shaft assembly includes an elongate generally cylindrical metal shaft having a plurality of spaced elongate upraised bosses extending substantially the entire length thereof. The spaced bosses define a plurality of spaced channels that also extend substantially the entire length of the shaft. The shaft carries an elongate hollow generally cylindrical core having a plurality of spaced inwardly projecting elongate bosses that extend substantially the entire length of the core and define a plurality of elongate spaced channels that also extend substantially the entire length of the core. The shaft and core are sized such that the core fits tightly on the shaft to inhibit rotary movement of the core with respect to the shaft. The core is made of material resistant to water absorption such as reinforced fiberglass or plastic.

Abstract: A track and flap assembly employs an elongate compressible foam member completely covering an elongate channel that carries a paper cutting tape. Between the bottom of the foam member and the top of the channel are one or two pivotally mounted resilient flap members that cooperate with the foam member to provide a desired frictional drag and exiting resistance to control the cutting tape movement during turn up. A compressed air passage is provided to allow for forced air removal of debris and other contaminants from the tape channel. The assembly is constructed in two configurations to accommodate different papermaking apparatus.

Abstract: An apparatus for cutting kernels of fresh corn from ears thereof and recovering kernels and cream therefrom for eating or preserving for future eating. The apparatus comprises a hand-held electric drill having a drill bit adapted to grip the ear at its stalk-end while the drill rotates the ear about the axis of the drill while pressing the ear into cutting tube having screw points projecting inwardly thereof causing said kernels to be ripped from the ear and discharged along with corn cream downwardly by gravity into a receiver for further processing.

Abstract: The broadband surface-like absorber of the invention is used, in particular, for absorbing troublesome airborne noise in the acoustic frequency range. The broadband surface-like absorber, which operates on the Helmholtz resonator principle, is distinguished by a checkerwork of irregular construction, the webs of which are aligned with their narrow sides perpendicular to the principal surface of the perforated plate and the side edges of which are connected in a sound-pressure-resistant and fluidtight manner on the sound side to the rear side of the perforated plate and, on the rear side, to an extended-area cavity boundary aligned with the same orientation as the perforated plate to form differently tuned chamber resonators.

Abstract: A system and method for control of the field of view of one or more cameras for providing that one or more subjects are to be in a single field of view (“share view”) wherein the system will automatically calculate the values for the various field of view variables to provide the appropriate camera operation. Various computer-controlled programs are included to operate the system including programs for the integration of camera operation and automatic tracking of the subjects present. The system is designed for video and it can automatically add and remove subjects from a share view.

Abstract: This invention relates to a golf putter having a bulbous mallet head joined to an upright shaft having a tapering grip that is at least flat on one of its sides and may be square in cross-section over its entire length and extends from the upper extremity of the shaft to adjacently above the head. The juncture of the shaft to the head is in the form of a goose-neck from adjacent the lower end of the grip to a rear entry into the head.

Abstract: A method and apparatus for magnetically separating magnetizable particles from a mixture of magnetizable and nonmagnetizable particles of similar size and density by passing the particles through a magnetic field generated by a cylindrical coil around the outside of the column of the separator, and enhanced by a ferrous metal mass or ring within the column located generally centrally of the coil.

Abstract: An adjustable splitter assembly at any position along the spiral trough and the splitter is angled to a fixed position pressed against the trough and locked against movement by a long arm selectively clamped in one hook of a retainer having spaced hook sockets, the retainer being attached to the outer rim of the trough either upstream or downstream from the splitter. The splitter may be angularly adjusted to position its leading edge at different locations along an arc with respect to the stream of particles flowing down the trough by moving the arm to another selected hook socket.

Abstract: A rug underlay formed of a compressed central mat of needle-punched waste or recycled fibers, the upper layer of which is heat fused by a drum to provide a chevron design of lands and grooves alternating between adjoining squares and a lower layer of elastomeric material coating the mat and embossed with a pattern of geometric formation.

Abstract: A handlebar adapted to be fitted onto the handles of a wheelchair having two substantially parallel handles, together with an improved push-button mechanism for locking the handlebar securely into position. The handlebar is designed with multiple ergonomically correct gripping stations which reduce strain on the hands, wrists and forearms of a person using the handlebar. Methods of retrofitting existing wheelchairs, as well as tools used in performing the retrofitting operation, are also provided.

Abstract: An ankle holster system, for carrying a concealed handgun includes a vertical support member that engages footwear worn by a user to provide vertical support for a holster and handgun. Cooperating releasable fasteners are mounted on the holster and the support member for securing the holster to the support member. A retainer strap wraps around the leg and the holster to secure the holster against rotative movement and attaches to the holster by another pair of cooperating releasable fasteners. The support member may include a strap to secure it to the leg of a user in the case of a heavy gun and holster that could cause outward bowing of the support member. The support member includes a planar metal element that can be bent in its plane and perpendicular to its plane but is rigid in the vertical direction to minimize vertical movement of the holster but allow for flexing necessary at the ankle and foot. The system includes a support member for use with boots and a longer support member for use with shoes.

Abstract: A severe storm warning system includes an atmospheric pressure sensor utilizing an air-filled chamber with a first pressure sensor mounted between the interior of the chamber and the atmosphere and being located within the chamber interior and a second pressure sensor mounted between the interior of the chamber and the atmosphere and being located outside the chamber. Both sensors are formed of multiple-plate, floating plate capacitors which are movable in response to pressure changes. Electronic circuitry periodically determines what pressure changes have occurred and compares the changes to the changes associated with a predetermined signature of the type of severe storm being determined. Indicators including alarms are provided if a known sequence of pressure changes is detected.
