Abstract: Abstract of the Disclosure Improved method and apparatus for supporting photographic sheet materials in intimate surface contact during contact exposure includes a flexible membrane which forms a common boundary wall between two gas-tight chambers.  Air at ambient pressure is admitted to one chamber at a controlled rate slower than air is evacuated from the other chamber containing the photographic sheet materials.  Progressive expansion of the surface area of contacting force assures that residual volumes of air between photographic sheets are squeezed out in an orderly pattern and not trapped in isolated pockets that distort resulting photographic images.

Title: Soil chemical sensor and precision agricultural chemical delivery system and method
Inventor: COLBURN JOHN W JR
IPC: A01C21/00
Filed: 1989-02-28
Granted: 1993-03-02
Abstract: ABSTRACT OF THE INVENTION      A real time soil chemical sensor and precision agricul-tural chemical delivery system includes a plurality of ground-engaging tools  in association with  individual  soil sensors which measure soil chemical levels.  The system includes the addition of a solvent which rapidly saturates the soil/tool interface to form a conductive solution of chemicals leached from the soil.  A multivalent electrode, positioned within a multivalent frame  of  the  ground-engaging  tool,  applies  a voltage or impresses a current between the electrode and the tool frame.  A real-time soil chemical sensor and controller senses the electrochemical reaction resulting from the appli-cation of the voltage or current to the leachate, measures it by resitivity methods, and compares it against pre-set resis-tivity levels for substances leached by the solvent.   Still greater precision is obtained by calibrating for the secondary current impressed through solvent-less soil.  The appropriate concentration is then found and the servo-controlled delivery system applies the appropriate amount of fertilizer or agri-cultural chemicals substantially in the location from which the soil measurement was taken.

Abstract: ELECTROMAGNETIC CLUTCH HAVING A STRUCTURE FOR REDUCING TORSION          ABSTRACT OF THE DISCLOSURE       An electromagnetic clutch according to the present invention includes a first rotatable member made of magnetic material and a second rotatable member connected to a driven member. An annular magnetic member is slidably connected to the second rotatable member so that the annular magnetic member can be capable of axial move-ment within a limited range. The annular magnetic member faces the axial end surface of the first rotatable member with an axial air gap therebetween. An electromagnet is associated with the first rotatable member to attract the annular magnetic member to the axial end sur-face of the first rotatable member so that the rotational force of the first rotatable member is transmitted to the second rotatable member through the annular magnetic member by pulling the annular magnetic member into full contact with the axial end surface. The first rotatable member comprises an annular main body and an annular pul-ley member. The annular pulley member surrounds the annular main body with an annular gap therebetween. An annular elastic member for reducing torsional forces and vibration in the second rotatable member is disposed in the annular gap between the annular main body and the annular pulley member.

Title: Process for high speed, multi-end polyester high performance tire and industrial yarn
Inventor: ROWAN HUGH H
IPC: D02J1/22
Filed: 1989-05-11
Granted: 1994-04-05
Abstract: ABSTRACT OF THE DISCLOSURE            This invention provides an improvement in a high speed process to produce high performance multi-end polyester yarn.  The process is extruding molten polyester from a spinnerette to form filaments, then cooling, lubricating and advancing the filaments to a forwarding roll system at the speed of from about 1000 - 4000 meters per minute so that a partially oriented yarn is produced, then feeding the filaments from the forwarding roll system to a first draw roll system to partially draw the yarn, then feeding the partially drawn yarn to a second draw roll system having a draw point localizing device then feeding the filaments from the draw roll system to a conditioning roll system and finally taking up the filaments.  The improvement is the use of matte finish on godet rolls having an arithmetic mean roll surface roughness value of from between about 35 microinches and about 120 microinches to feed and withdraw yarn to and from a draw point localizing device in the second draw roll system.  This combination enables multiple ends of the filaments to be advanced through a single set of forwarding, drawing and conditioning rolls and yarn mechanical quality remains at a high level of acceptance.
