Title: Ceramic bearing
Inventor: MOMOSE TERUNOBU
IPC: F16C33/04
Filed: 1990-10-01
Abstract: Abstract of the Disclosure This invention is to provide a ceramic sliding bearing which is possible to support the axis to which the radial load and the thrust load are applied simultaneously or selectively, and also this invention is to provide a bearing having a small number of parts by constructing the inner and the outer rings by means of ceramics.      The ceramic product of this invention is characterized by combination of the ceramic inner ring and the ceramic outer ring wherein said ceramic inner ring which forms an axial hole for engaging the axis at the center thereof, forms a cylinder surface parallel to the axial center of the axial hole on the outer periphery thereof and forms an approximately rectangular plane to the axial hole at the end portion thereof, and said ceramic outer ring having a cylindrical surface at the inner periphery which contacts slidably with the outer periphery of the ceramic inner ring and a plane which contacts slidably with a plane formed at the end portion of the ceramic inner ring connecting with said cylindrical surface.      The axis is engaged with the axial hole formed at the inner ring, the sliding does not happen between the axis and the inner ring.  accordingly there is no fear of occurrence of the abrasion to the axis even after long period of use.      Since the inner and outer rings are constructed by ceramics, the sliding friction is small thereby being able to increase the heat generation due to the friction. Further, since the expansion due to the heat is small, the generation of stress regarding a machine frame and axis, etc. is possible to decrease.

IPC: H02K9/06
Filed: 1991-04-11
Abstract: The present invention is an air conditioner with tangential blowers having an arrangement for cooling the blower's driving motor.  The motor is attached exteriorly from the air moving chamber and the sidewall through which the motor is attached to the blower includes an axially located aperture.  Blade extensions of the blower near the aperture induce an air flow through the aperture, and the induced air flow passes through the motor to carry away undesired heat. A seal can be formed between the motor and sidewall so that the induced air flow must pass through the motor.

Abstract: Quantitative Analysis For Diabetic Condition Predictor Abstract An enhanced quantitative assay for chiro-inositol concentration can be used to determine insulin-resistance, or  a  predisposition  to  the  development  of  insulin-resistance, in type I and type II diabetics.  Spot urine or  serum  samples  reflecting  concentrations  of  chiro-inositol below about 1.0 micrograms/ml in urine or 0.1 micrograms/ml in serum are indicative of a predisposition to   the   development   of   insulin-resistance,   while concentrations  below  about  0.3  micrograms/ml  or  0.03 micrograms/ml in serum are associated with actual insulin-resistance  symptoms.    The  assay can be  employed for patient diagnosis, insulin therapy monitoring, and family screening.

Abstract: Method and apparatus for wrapping a signature bundle by moving a wrapping sheet into the path of movement of a bundle,  the sheet being maintained in self-supporting fashion by imparting a bend thereto as it is fed to the wrapping station.  The bundle "crashes" into the sheet causing it to collapse and wrap itself about the bundle.  When the wrapping operation is completed, the wrapping sheet is wrapped around three contiguous surfaces of the bundle. The sheet is automatically cut and a new wrapping operation is initiated.  The wrapping sheet may be printed upon by an ink jet printing characters "on the fly".  The characters are printed backwards and "bleed through" the wrapping sheet to appear in normal manner.

Title: Absorbent article exhibiting improved fluid management
Inventor: COE LOUISE C E
IPC: A61F13/511
Filed: 1991-10-23
Abstract: An absorbent article is disclosed which exhibits improved fluid management.  The article includes an absorbent having first and second oppositely aligned surfaces and a longitudinally extending central axis.  A bicomponent cover is positioned over the first surface of the absorbent and includes a first and a second material. The first material has openings formed therein and is aligned along the longitudinally extending central axis of the absorbent.  The second material is nonapertured and is secured to, or positioned adjacent to, the outer periphery of the first material.  The first and second materials cooperate to enclose the absorbent.  Positioned between the first material and the first surface of the absorbent is a separation means.  The separation means directs fluid from the body downward, in the z direction, away from the bicomponent cover, and outward in the x and y directions to provide a more efficient use of the absorbent material.  The absorbent article further contains a liquid-impermeable baffle which is positioned adjacent to the second surface of the absorbent.

Title: Peroxyacid manufacture
Inventor: TROUGHTON NICHOLAS A
IPC: C07C409/40
Filed: 1990-05-21
Abstract: In one class of processes for making poorly soluble organic peroxyacids the corresponding carboxylic acid is reacted with hydrogen peroxide in a reaction medium containing a high concentration of sulphuric acid. The presence of such constituents in the reaction mixture and the manner of the reactants and the way in which they are brought into contact, can result in the processes being hazardous. In the present invention, hazard problems are reduced or eliminated by first dissolving the carboxylic acid in concentrated sulphuric acid, secondly forming a Caro's acid solution containing a complementary amount of sulphuric acid and hydrogen peroxide within a predetermined range, and then introducing the carboxylic acid solution at a controlled rate into the Caro's acid solution, often over a period of from about 30 to 90 minutes, with agitation and temperature control. The compositions of the two reactant solutions are precalculated relative to each other such that the A value (weight ratio of sulphuric acid to the the combined weight of it and water) either increases during addition of the carboxylic acid solution or if the latter is relatively less insoluble, stays the same or increases. The solutions are preferably formulated to provide an A value at the end of the reaction period selected in the range of around 0.7 to around 0.8, at a temperature of around 20 to 45°C, the more soluble tending towards the lower end of each range and the less soluble towards the upper end of each range. The process is especially suitable for making poorly soluble aliphatic mono or diperoxycarboxylic acids such as peroxynonanoic acid or diperoxydodecanedioic acid, or for aromatic group substituted peroxyacids in which the peroxydation occurs in a primarily aliphatic environment, such as phthalimidoperoxyhexanoic acid. In another aspect, the present invention provides the peroxyacid 6,6'-terephthal-di(amidoperoxyhexanoic) acid and a process for preparing this compound.

Title: Dual wound trip solenoid
Inventor: PATEL UMESH C
IPC: H01H71/28
Filed: 1992-03-26
Abstract: 56,284 Abstract of the Disclosure A multiple-pole ground fault interrupter, enclosed in an insulated housing, formed with multiple compartments, includes ground fault detection circuitry for detecting ground fault current that can be a personnel hazard.  The ground fault interrupter includes a single trip solenoid assembly   having   multiple   windings,   each   winding corresponding to one of the poles.  The trip solenoid is mounted  on  a  printed  circuit  board  and  electrically connected to the ground fault detection circuitry disposed thereon.  The printed circuit board together with the trip solenoid assembly is disposed in a single compartment which reduces  the  amount  of  interconnection  wiring  between compartments, which, in turn, results in a reduced cost to manufacture the device.  The use of a single trip solenoid assembly also results in the use of less components which further reduces the cost of manufacturing the device.
