Title: Method of sealing a fastener bore and sealed nut fasteners
Inventor: MUELLER RUDOLF R M
IPC: F16B37/14
Filed: 1993-11-25
Abstract: ABSTRACT OF DISCLOSURE   A method of sealing a bore, such as the threaded bore of a fastener, wherein the sealing element is preferably formed in place. The preferred sealing element is formed of a heat softenable plastically deformable material, such as a thermo-plastic resin, which is heated and deformed radially in the bore into a mechanical interlock with the bore inside the surface, such as thread. In the preferred method,     a plunger or ram is driven into the sealing element which is supported on a die element in the bore. In the most preferred method, the ram simultaneously heats and deforms the sealing element, sealing the bore opening. The preferred female fastener element includes a generally tubular body portion having an axial bore which may be threaded adjacent one end. The sealing element seals the opening to the bore and the opposite end may be sealed with a disk spaced from the threads and forming a chamber. The chamber receives the sealing element upon receipt of a male threaded element, such as a bolt, in the female fastener bore. The sealed fastener may then be installed in a structural element, such as a bracket, which may then be coated or encapsulated without contamination of the bore or threads.

Title: An elastomeric propeller having a flexible elastomeric covering
Inventor: EHRENSKJOELD NILS O
IPC: B63H1/15
Filed: 1992-10-29
Abstract: A propeller for e.g. a ship has a central hub (34) with a plurality of propeller blades (12). Each blade (12) is composed of a flexible elastomer covering (14) of e.g. rubber which is vulcanized firmly on a core (13). The core (13) and the elastomer covering (14) are moulded and vulcanized to an integral unit which, without expensive after-treatment, forms a propeller having a finished smooth surface and a consistency capable of absorbing and damping the impact and shock pulses from the reaction forces of the water. The elastomer covering is not vulcanized firmly on the entire surface of the core, thereby forming on both sides of the core a compartment (16) which can be filled via a filling valve (18) with a fluid under pressure, e.g. air or water. The elastomer covering is adapted such that when deformed it passively adjusts the pitch of the blade optimally to the instantaneous state of operation. When selectively pumped-up, the propeller can moreover actively be given the geometrical shape best suitable for any purpose.

Abstract: In a machine for the application of gypsum board, it is known to have an aluminum frame consisting of one main beam and three cross beams which is secured by its centre to a pneumatic cylinder by means of a universal joint. At one end, two legs extend downwards holding the end of the frame 24 inches off the floor. When the base of the pneumatic cylinder is placed on the floor the frame is suspended at an angle to the ceiling allowing the operator to place the gypsum board upon it's top. In this invention stays have been welded at one end of the cross beam at each end of the frame. At the opposite end of the centre cross beam a retractable lock has been fastened, embracing a small pneumatic cylinder for it's operation. When the retractable lock is engaged the gypsum board is forced against the two opposite stays thus securing the board to the frame. Two handles have been fastened to the underside of the main beam thirty six inches apart and thirty inches from the centre. By gripping both handles the operator can easily balance the loaded machine on the upright cylinder. A control valve has been fastened to one handle giving the operator finger control of the main cylinder and the retractable lock cylinder thereby allowing him/her to guide the board into place by extending the main cylinder to the necessary height and locking it there until it is properly secured. Both ends of the frame are telescopic to accommodate various board lengths.

Title: Apparatus for weighing and identifying characteristics of a moving vehicle
Inventor: MUHS JEFFREY D
IPC: G01G19/02
Filed: 1993-04-01
Abstract: Apparatus for weighing a vehicle in motion is provided by employing a plurality of elongated fiber-optic sensors (32) defined by an optical fiber embedded in an encasement of elastomeric material and disposed parallel to each other on the roadway in the path of moving vehicles. Each fiber-optic sensor is provided with contact grid means which can be selectively altered to provide the fiber-optic sensors with sensitivities to vehicular weight different from each other for weighing vehicles in an extended weight range. Switches (24, 26, 28 & 30) are used in conjunction with the fiber-optic sensors to provide signals indicative of the speed of the moving vehicle, the number of axles on the vehicle, weight distribution, tire position, and the wheelbase of the vehicle. The use of a generally N-shaped configuration of switches also provides a determination of the number of tires on each axle and the tire footprint. When switches in this configuration are formed of optical fibers, the extent of light transmission through the fibers during contact with the tires of the vehicle is indicative of the vehicle weight.

Filed: 1994-10-24
Abstract: Food products having high dietary fiber content and unexpected organoleptic characteristics, the invention takes the form of a substantially solid or semi-solid substrate formed primarily of dietary fiber soaked in or permeated by a flavorful material such as a natural juice, liquefied or pureed fruit or the like, the combination then being at least partially lyophilized to a solid or semi-solid consistency.  The concentration of the natural juice or other flavorful material within a framework or lattice provided by the dietary fiber causes a burst of flavor to be experienced when eaten.  While the lyophilized substrate can preferably be consumed as a bar-like comestible with or without the addition of other materials such as coatings, fillers and the like, the invention contemplates the formation of the substrate as flakes, as a cookie, as a candy such as a semi-soft roll or sheet consumed flat or as a rolled sheet among other forms.  In all forms, the inventive food product provides healthful benefits known to be associated with desirable intakes of dietary fiber and tasteful enjoyment due to taste characteristics not previously present in food products of high fiber levels.          The invention further relates to the methodology for preparation of the present food products.

Inventor: SUZUKI TERUHIKO
IPC: H04N19/102
Filed: 1994-03-01
Abstract: Mismatch error occur in the local decoder of a MPEG-standard compressor for a motion picture signal, and in an MPEG-standard expander for a compressed motion picture signal. This is because of the lack of a standard for rounding results of *.5 (* is an integer) obtained when a set of transform coefficients resulting from compressing the motion picture signal is inversely orthogonally transformed.   The invention prevents mismatch errors by preprocessing the set of transform coefficients prior to the inverse othogonal transform (15).   The transform coefficients in the set are summed (23A) and the parity (odd or even) of the sum is judged (21). When the parity of the sum is judged to be even, the parity of one of the transform coefficients in the set is inverted (28) to provide a parity-inverted transform coefficient. This makes the parity of the sum odd. Then, when the set of transform coefficients indluding the parity-inverted transform coefficient is inversely orthogonally transformed (15), none of the results of the orthogonal transform will have a value of *.5.
