Inventor: GRAHAM JOSEPH
IPC: C08K9/04
Filed: 1989-12-29
Abstract: FN: 4363h. CAN lA            OIL TREATED MINERAL FILLER FOR ASPHALT                  Abstract of the Disclosure Use of surface modification treatment on mineral fines to obtain higher filler loadings in asphalt used for roofing shingles.  Mineral fines are coated with oil such as a petroleum oil at about the 0.25 - 1.0 percent level before they are incorporated into molten asphalt.  This treatment makes minerals which otherwise would be uncompetitive with traditional fillers, such as limestone, sufficiently compatible with asphalt to be a viable alternative to limestone.  Nepheline syenite mineral fines treated in this manner have been successfully incorporated into asphalt for shingles at a loading of 65 - 70%.

Inventor: BELL ISAAC M
IPC: H03K17/041
Filed: 1990-02-22
Abstract: ABSTRACT First and second signals, and first and second bias levels of different magnitudes are applied to respective inputs of a level-gated-analog-OR circuit comprising a non-additive mixer (NAM) circuit. The input receiving the greater bias level is enabled thereby to convey its respective signal to the output of the NAM circuit, and the input receiving the lesser bias level is prevented from conveying its respective signal to the output of the NAM circuit. In another embodiment, the NAM circuit is used in cascade with a low cost CMOS switch to provide a cost effective switch for television signals.

Abstract: TITLE : An improved moveable valve assembly for liquid atomizers ABSTRACT OF THE DISCLOSURE    The  present  invention  relates  to an  improved moveable valve assembly  for  liquid  atomizers  which  mainly  comprises  a  piston assembly and a moveable  valve  body  including  an  upper  solid rod and a lower hollow sleeve.  The upper solid rod consists of three rod portions each having a  different  diameter  form the other such that the  intersection  between  any  two  of  three  rod  portions may be respectively formed into a tapered shoulder , a  recess  or  a  socket with a flattened shoulder to serve as pressure  concentrating  points whereby  the  pressure  generated by the pressurized  liquid  can  be efficiently applied to those  pressure concentrating  points in order to overcome the compression force provided by  a spring located under the  moveable  valve  body  and  in  turn  to  enable  a  valve  head to  disengage  from  a corresponding exhaust hole.   The lower hollow sleve  is provided  at  the  lower  end of its vertical side with an outward  projection and  with  an  inclined  extension  below  the projection  end  with an inclined extension below the projection such that the pressure generated  by the pressurized liquid can be applied to the upper side of the projection to force the moveable valve body downward while the pressure applied  to  the  inclined extension makes an inner arcuate flange of the inclined  extension  closely  contact a valve  hole  so as to achieve a fluidtight  effect , and in turn to expedite the formation of pressurized liquid in a compressed chamber.   In addition, the lower hollow sleeve may be provided with a thick solid  portion  wherein  the  top  side of the thick solid portion is formed  with  a  plurality  of  tooth-shaped annular  portions  to enforce the pressurizing offect applied thereto whereby the atomization of the liquid can be rapidly completed.
