Title: Compensation for diaphragm control in slr camera

Abstract: COMPENSATION FOR DIAPHRAGM CONTROL           IN SLR CAMERA        Abstract of the Disclosure A camera comprises a camera body and first and second lens assemblies interchangeably insertable into the camera body.  Each lens assembly has a displaceable actuator, a diaphragm adjustable between a maximum aperture and a minimum aperture value responsive to displacement of the actuator and a transducer for generating a first signal representative of the displacement of the actuator.  In the camera body, there is generated a second signal repre-sentative of the desired aperture value of the diaphragm for correct exposure.  The first and second signals are compared and the actuator of the lens assembly inserted in the camera body is displaced responsive to the comparison to stop down the diaphragm from the maximum aperture value toward the minimum aperture value until the first and second signals assume a predetermined relationship.  The diaphragm of the second lens assembly is maintained at the maximum aperture value during an initial portion of the displacement of the actuator.  Preferably, the initial portion of the actuator displacement is sufficient to compensate for the deviation in aperture value, maximum aperture value, and minimum aperture between the first and second lens assemblies.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is a device and method for controlling stress within an individual,  The device indi-cates the degree of stress an individual is undergoing and methods that may be used to control and overcome the stress.          The device of the present invention is a card which can easily be carried anywhere.  On the face of the card is a temperature sensitive strip which is placed next to an extremity of the individual utilizing the card.  The temper-ature sensitive strip responds to the temperature of the extremity by changing its characteristics in a way that may be observed by the individual to indicate the degree of stress within the body.  The temperature of the extremity indicates the stress within the body based on a physiolog-ical principal in that blood moves away from the extremities when one is in the state of anxiety or tension into the inner vital organs, making the extremities cold.  Since the strip responds to temperature, it will indicate the degree of stress.  The card also contains several techniques for controlling stress and bad habits.

Abstract: Abstract of the Disclosure A process and apparatus are disclosed for accelerating the drying of green and/or partially dried lumber.  The lumber is dried at pressures below standard atmospheric pressure to rapidly remove moisture from the lumber without degrading the wood structure.  A kiln for performing this function includes a chamber for a charge of lumber, an electrically activated flexible heating blanket to impart heat into the charge of lumber, a device for reducing pressure within the chamber, and a device for removing moisture vapor from the chamber.  The process for accelerating the drying of the wood includes the step of heating the wood piece in the chamber to a selected temperature.  The pressure in the chamber is reduced to a pressure at least as low as the vapor pressure of water at the selected temperature.  The wood is controllably heated to maintain the wood at the selected temperature while the pressure in the chamber is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE     A core holder is used in the nonsteady-state testing of permeability and other flow characteristics of a geological core sample.  A reference pressure reservoir assembly contains a predetermined volume of test gas at a known pressure, and a gas operated valve admits this test gas rapidly to the upstream end of the core sample.  The downstream end of the core sample is open to the atmosphere, and the pressure in the reference pressure reservoir assembly is monitored as it decays in time while the test gas passes through the core sample.  The gas-operated valve is formed of an upstream plug, a gland fitting the plug, and a valve stem fitting into a generally cylindrical cavity formed in the plug and gland.          The valve stem has an enlarged head at one end with an annular slot on a cylindrical surface thereof.  This structure minimizes turbulence in the flow of the test gas through the valve assembly.
