The thermosetting phenolic resin produced by the process  of  the  present  invention  not  only  displays superior  thermal  curing  characteristics  during  molding; the cured product fabricated by molding this resin also exhibits  good  physical  properties  such  as   improved mechanical strength and heat resistance.   Therefore,  the spherical thermosetting phenolic resin particles produced by the process of the present invention can be extensively used as molding materials, binders, adhesives, and in many other applications.

Abstract: ABSTRACT OF THE DISCLOSURE      A  process  for  producing  a  low-dust  transparent thermoplastic resin solution, which comprises centrifuging a solution  of  a transparent  thermoplastic resin optionally containing pure water to separate it into  a  resin solution phase and an aqueous phase, and separating  the  resin solu-tion phase from the aqueous phase and the  interface between them.  By this process, the number of dusts having a size of at least 0.5  m in the resin solution  can  be  decreased to 10,000 or less, preferably substantially zero,  per  gram of the transparent thermoplastic resin.

Granted: 1991-08-13
Abstract: ABSTRACT     A new crystalline borosilicate molecular sieve, boronaaronate, having a composition in terms of mole ratios of oxides:          0.9?0.2M2/nO;B2O3:ySiO2:zH2O wherein M is a cation of valence n, y is between 2 and about 700, and z is between 0 and about 200, and having a characteristic X-ray diffraction pattern.  The boronaaro-nate is prepared by reacting under crystallization condi-tions, in substantial absence of a metal hydroxide, an aqueous mixture containing an oxide of silicon, an oxide of boron, ethylenediamine, and an organic material com-prised of a heterocyclic nitrogen-containing aromatic compound or an aliphatic alcohol.  Boronaaronate is useful in hydrocarbon conversion processes.

Title: Method of manufacturing papermaker's felt
Inventor: PENVEN PATRICK H
IPC: D04H1/48
Filed: 1987-03-25
Granted: 1991-12-03
Abstract: Abstract The present invention provides a solution to the prior art problem of producing a high density papermkers batt fabric or felt which may be secured to an undamaged under layer in an economic  manner. The  present  invention  provides  these improvements by providing a batt which is comprised of a non-woven low melt scrim to which the batt material is initially needled. Subsequent to producing a batt of the required density, the batt may,  if desired, be needled or adhered to an under layer fabric. The completed felt will be subjected a heat pressing operation which will elevate the temperature of the batt to a temperature above the softening temperature of the scrim but below the melting point of the batt fibers.   In this manner,  the batt and under layer fabric are unified to produce a multilayer papermakers felt with minimum effort and disruption of the under layer.

Title: Plate-shaped heating element in particular for floor heating
Inventor: HAUGENEDER HANS W
IPC: F24D19/02
Filed: 1987-04-08
Granted: 1992-04-28
Abstract: Abstract A plate-shaped heating element, in particular for floor heating, consists of two plates of synthetic material defining a hollow space. Spacing elements are provided between the plates in a direction perpendicular to the plane of the plates, the spacing elements uniting the two plates. The spacing elements are arranged so as to form a first row along a first straight line, said first straight line being an extension of the axis of the joining element. All other spacing elements form further rows, said rows being provided along straight lines which again are provided parallel to the first straight line.

Title: Leak detector with two stage piston chamber
Inventor: JARR KLAUS D
IPC: G01M3/28
Filed: 1987-04-29
Granted: 1990-12-11
Abstract: ABSTRACT           A pressure sensing piston connected to a valve of a leak detector senses leakage of gasoline from underground piping and restricts the flow of gasoline through the piping whenever any leakage exceeds a certain, predetermined rate of flow.  The piston is shiftably received in a piston chamber and carries an inner cylindrical wall that is sealingly engageable with a mating cylindrical seal of struc-ture connected to the piston chamber whenever the valve of the detector is in a leak sensing position to enhance movement of the valve in accordance with relatively small changes in the volume of fluid within the region.  Once pressure in the piping has built to a value sufficient to raise the piston and disengage the walls from the seal, fluid from the piping is presented to the entire cross-sectional area of the piston chamber including the entire area of the piston face so that a greater volume in the piston chamber is presented to accumulate gasoline and to substantially preclude movement of the valve back to a reduced flow, metering position due to thermal contraction of gasoline within the piping. A venting device mounted in a passageway of the piston releases gasoline that would otherwise be trapped below the piston in areas outside of the wall as the piston is moved toward the bottom of the piston chamber.

Abstract: Abstract The present invention relates to novel specifically-substituted phenyl compounds, especially substituted di-tert-butyl  phenol derivatives,  which  are  effective  as  anti-inflammatory,  analgesic and/or antipyretic agents.   These phenyl compounds are substituted with a low molecular weight alkyl  chain  which  terminates  in  a  specific  unsaturated functional group.  These unsaturated functionalities are -C=CH,  C=CH2,  C=C=CH2, and aldehydes in the form of their acetals.  The novel compounds have the structural formula   with preferred compounds being those in which A' is -OH, A2 is -C(CH3)3, A3 is -C(CH3)3 and Y is a terminally unsaturated group.
