Abstract: ABSTRACT OF THE DISCLOSURE         The  process  for  obtaining  oil,  gas  and  other products from pyrobituminous shales and the like includes introducing crushed shale into a retort and contacting the crushed shale in the top portion of the retort with a stream of retort gases.   Hot gases are injected at an intermediate point of the retort and a stream of cold gases are injected at the bottom of the retort.   The gaseous retorted matter above the zone where the shale undergoes pyrolysis is removed and directed to a cyclone for separation of heavy liquid components from a gaseous stream.  The gaseous stream is then purified  and compressed with a portion of the compressed stream being heated and reinjected as the stream of hot gases into the retort.  The other portion of the compressed stream of  gases  is  cooled  and  a  liquid  component  consisting primarily of water and heavy oil is separated therefrom in a spray tower.  The water portion is separated from the oil and recirculated to the spray tower while a part of the oily portion is separated for reuse outside the process with the remainder being recycled to the cyclone.   A portion of the compressed gases from the cyclone is cooled and injected into the bottom of the retort as the stream of cold gases.

Title: Matted photographic imaging materials
Inventor: FAUTZ MANFRED
IPC: G03C1/95
Filed: 1988-01-07
Granted: 1997-03-11
Abstract: The matting agent particles of matted photographic imaging materials contain a finely divided solid as well as a dye that is only present at the image-forming points after exposure and development of the material.  The starry night effect is thereby avoided.  The dye can be formed during exposure and development from a precursor, e.g., from silver halide or from couplers for color photography or for diazo processes.

Abstract: An improved (N - 1) adding operation conference telephone communication method through an electronic exchange in which the telephone communication signals on speakers in a time sharing multiplexed telephonic communication path are added, the telephone communication signal on any particular speaker himself is subtracted and the resulting telephone communication signals are transferred to the remaining respective speakers.  The levels of the telephone communication signals are monitored which are obtained  as the result of the (N - 1) adding operation.  When the telephone communication signals exceed a preset threshold level. they are selectively attenuated and transferred to the remaining respective speakers.  The selective attenuation of the telephone communication signals which have exceeded the threshold level is released a predetermined time after conditions under which the threshold level is exceeded have disappeared to thereby prevent satisfactorily the deterioration of the voice quality which would otherwise be feared.

Filed: 1989-09-21
Granted: 1991-07-09
Abstract: ABSTRACT          An improved cooktop mounting arrangement for a range with an upswept lift-up cooktop including a pair of upper pivot members extending from opposite sides of the upswept section of the cooktop, a pair of spaced lower pivot members extending from opposite sides of the cooktop near the intersection of the upswept section and the cooking surface section, and corresponding upper and lower guides supported from the main range body.  The upper and lower guides are cooperatively configured to respectively simultaneously guide the upper pivot members through a vertically oriented arcuate path extending downwardly and forwardly and to guide the lower pivot members through a horizontally oriented path extending generally forwardly and upwardly as the cooktop moves from its lowered position to its raised position.  This arrangement eliminates the need for a vertical gap for clearance between the upswept section and overhanging structure when the cooktop is in its lowered position, and also eliminates the need for space behind the upswept section to accommodate rearward movement of the upswept section.

A case coupler is mounted in the opening, and has an annular projection protruding through the opening.   A first dynamic transducer is mounted within that annular projection. A second dynamic transducer is mounted to the case coupler opposite the  first transducer.   The case coupler  includes  an  isolating  plate,  positioned between the first and second transducers, for sonical-ly isolating the first transducer from the second.  A grill plate is mounted over the annular projection, for providing a load to the first transducer.   The isolating plate includes an opening, located outside the periphery of the annular projection, for allowing the passage of sound from the second transducer to the listener.  A support assembly is connected to the face plate, and a cup assembly in turn connected to the support assembly.  The support assembly includes means for allowing relative pivoting movement between the cup assembly and the face plate.  The support assembly includes a ball and socket arrangement resulting in the relative motion allowed between the cup assembly and the face plate being biaxial.  A bellows member is positioned between the cup and the face plate for damping movement between the cup assembly and the face plate, and for enclosing and directing sound waves generated by the transducers.  A unique plug arrange-ment  is  provided  for connecting the  cord to the headphone apparatus.
