Abstract: DENTAL SPLINT          Abstract of the Disclosure A dental splint for securing one or more loose, mobile teeth to one or more healthy abutment teeth is provided.  The splint utilizes a dental preparation in the lingual or occlusal surface of the teeth and a bar.  The preparation should conform to the cross-sectional configuration of the bar with a flat floor, and walls perpendicular thereto.  The bar is then chemically bonded to the tooth structure, and a composite covers the bar which is also chemically bonded both to the tooth structure and to the bar.  The splint, then, is a unitary structure.

Abstract: SEAT MOUNTING FOR OFFICE CHAIRS                         ABSTRACT      Seat mounting, especially for office chairs, having a frame attachable to the lower side of the chair and provided with a pivotal holder for the back-rest and a pivotal holder for the support column of the chair. Secured between said holders and said frame are gas springs counteracting pivotal movement of said holders and, when actuated, permitting said holders to be pivoted. To actuate said gas springs an operating member is pro-vided which is rotatable in opposite directions and also is vertically movable. Upon rotation of said operating member in one direction, one of said gas springs is released to permit pivotal movement of the associated holder. When said operating member is rotated in the opposite direction, the other gas spring is re-leased to permit pivotal movement of the associated holder. When the operating member is raised, both gas springs are released to permit simultaneous pivotal movement of the back-rest and the seat.

Granted: 1995-12-12
Abstract: In a manually operable discharging apparatus (1), the discharge nozzle (25) has an at least two-stage atomizer (100), in which the medium flow, following preatomization, is atomized by surge-like acceleration with a whirled, fine compressed air flow, e.g. according to the Laval effect, so that even finer droplets are obtained.  For this purpose to the dis-charge nozzle (25), a separate compressed air channel portion (89) upst-ream of the end opening (80) supplies compressed air from a time immed-iately before the supply of medium to a time after its supply.  The compressed air can be produced in simple manner by a compressed air pump (50) combined constructionally with the medium pump (2) and oper-able together therewith by means of a single handle (22) and which in the extension of medium pump (2) is provided immediately adjacent to its outer end and whose pump cylinder (52) is formed by the cap-like handle (22).  The compressed air flow can also be passed to other points of the discharging apparatus (1), e.g. for cleaning the medium outlet channel (24) for discharge nozzle (25) and can be used for control func-tions for valves, particularly outlet valves.

Abstract: ABSTRACT OF THE DISCLOSURE     A     pressure regulating system for a hemodialysis machine utilizes a deaeration pump and a regulator in a deaeration loop for minimizing pressure and flow transients in a heated water supply.   The deaeration loop has the pump, a deaeration pressure regulator, a deaerator, and a back pressure regulator.   The pump produces a negative pressure in heated water entering the deaeration pressure regulator to circulate the water in the deaeration loop and to enhance removal of air from the water.   The back pressure regulator controls the loop water pressure to a value greater than the incoming water pressure and supplies water to the dialyzer system of  the machine isolated from supply water pressure and flow variations.

Abstract: ELECTRONIC GOVERNOR INTERFACE MODULE                   ABSTRACT OF THE DISCLOSURE     An electronic module interfaces a microcomputer with the fuel injection equipment of a diesel engine so that the microcomputer, acting through the module, exercises control over the fuel injected into the engine.  A pulse width modulated fuel deliver control signal issued by the microcomputer is transmitted through the module to energize a proportional solenoid actuator that positions the fuel rack.  Rack position is sensed by an eddy current sensor that provides feedback through the module to the microcomputer so that the rack position is closed-loop controlled.  The sensor has a measurement coil for measuring rack position and a reference coil for temperature compensation.  The two coils are connected in a circuit of the module that produces a pulse width modulated feedback signal which is supplied to the microcomputer in synchronism with the fuel deliver control signal.  This latter circuit comprises an L/R monostable for each coil and pulse stretchers that stretch the output pulses from the monostable The pulse stretchers' outputs are supplied to a gate that develops the feedback signal to the microcomputer.

Title: Turbine blade fatigue monitor
Inventor: KENDIG ROBERT P
IPC: G01M99/00
Filed: 1989-01-30
Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE             An on-line vibratory fatigue monitor measures displacement of an object such as the blade of a turbine rotor to generate a displacement signal and calculates accumulated fatigue in the object in dependence upon the displacement signal.  The displacement of the object may be detected by passive proximity probes which generate signals indicative of changes in magnetic flux or capacitance between the sensor and the turbine blade.  An analog/digital converter converts the signals from the probes to digital signals indicating displacement of the turbine blades.  The digital signals are processed, preferably by taking a Hilbert transform, to detect the amplitude envelope and instantaneous frequency of the displacement.  The amplitude and frequency are combined with steady state stress on the object to determine fatigue usage which is accumulated by constantly monitoring vibratory displacement and changes in the steady state stress.

Granted: 1993-07-27
Abstract: ABSTRACT OF DISCLOSURE          The invention herein is directed to article and process for making it.  The article is characterized by a substrate composed of a ring-opened polymer of a norbornene-type monomer having tricyclic or higher cyclic structure and a polymer sheet tenaciously adhering to the substrate.          The process includes the steps of positioning the polymer sheet in a mold, flowing the monomer in a liquid state in a plurality of streams into the mold, polymerizing the monomer in the mold by ring-opening of the monomer, and removing the article from the mold with the polymer sheet on at least one outer surface thereof.  Metathesis catalyst and cocatalyst components are added to at least one of the monomer streams along with a halogen source. The advantages realized hereby include good adhesion between the substrate and the polymer sheet without the use of a coupling agent or an adhesive, reduced odor which is realized by blocking of  at least one surface of the article, and improved surface characteristics.  The process can be carried out by reaction injection molding (RIM) in substantial absence of a solvent or diluent.  In such an operation, solubility of the catalyst and cocatalyst components is desirable.

Abstract: Methods of Producing Microwave Devices Abstract This invention concerns with microwave devices including resonant elements made from dielectric materials represented by the nominal formulas Ba2Ti9O20, BaTi4O9, ZrTiO4, ZrTiO4 (Sn) and the like. The resonant element is produced conventionally by a process including numerous steps of mixing, drying,screening, calcining, ball milling, drying, screening or remilling and spray drying, forming and sintering. These steps may take 72 hours or more, prior to the forming step, and are labor and energy consuming. The improvement resides in the use of a reduced number of steps which include mixing precursor powders with addition of water and dispersants, spray drying or flocculating and drying the mixed formulation, forming and reactively sintering, so as to reduce the total processing time, prior to the forming step, to from about 8 to 24 hours. The sintering step is conducted in an oxygen-enriched atmosphere and may be followed by soaking and annealing to enhance the Q characteristics of the element. Resultant product characteristics, e.g. Q's, are superior or at least comparable to those of the conventionally produced product.
