Abstract: ABSTRACT OF THE DISCLOSURE     A method of photographing human body tissue comprises directing towards one side of the body tissue a shielded light transmitting instrument and actuating a first low intensity light emitter in the instrument which comprises a tungsten fila-ment, and which emits light within the blue to infrared spectrum, to transilluminate the body tissue and visually indicate the presence of any anomalies in the tissue.  A second light emitter emitting light within the blue to infrared spectrum is then actuated in the instrument to emit a second light of higher in-tensity than the light from the first emitter to make an ex-posure on infrared sensitive film at the opposite side of the body tissue.  The use of such film provides a substantially en-hanced image of anomalies.

Abstract: QUICK RELEASE COUPLING FOR CONNECTION            BETWEEN SHAFTS                 Abstract of the Disclosure A quick release coupling for connecting a driven shaft having a universal type joint at one end thereof, with a drive shaft, includes a coupling box surrounding the drive shaft and a coupling sleeve carried at the end of the driven shaft for axially receiving an end of the drive shaft.  An annular groove is located on the drive shaft and a ball-catch mechanism is carried by the coupling sleeve for snap acting cooperative engagement with the annular groove to produce a positive form fitting engagement between the drive shaft and the coupling sleeve.  A locking ring is carried for movement on the coupling sleeve between a release position and a locking position for locking the ball-catch mechanism into engagement with the groove.  A spring is used to bias the locking ring into the locking position.  Means are provided for engaging the locking ring to hold it in the release position during insertion and removal of the drive shaft into and out of the coupling sleeve.  A release lever is pivotally mounted on the coupling box for engaging the locking ring to move it into a release position allowing the ball-catch mechanism to be released from the annular groove so that the shafts may be easily disconnected.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed herein is a single lever control for the throttle and clutch of a marine propulsion device including a housing pivotally supporting a shaft member for relative lateral or axial movement between first and second positions, a main control lever connected to the shaft member for common axial movement and for common rotary movement from a neutral position, a throttle drive member connected to the shaft member for common rotary movement and for relative axial movement of the shaft member, and a clutch shift drive member mounted on the shaft member for relative rotation and for common axial movement.  The clutch shift drive member includes a drive lug which, when the shaft member is in the first position, is receivable in and drivingly engages a drive notch in the throttle drive member to provide common rotary movement of these two members in response to pivotal movement of the main control lever from the neutral position.  When the shaft member is moved axially to the second position in response to outwardly lateral or axial movement of the main control lever, the clutch shift drive member is moved to a disengaged position wherein the throttle drive member can be rotated or pivoted relative to the clutch shift drive member by the main control lever so that the engine throttle can be operated indepen-dently of the clutch for engine warm-up.

Abstract: Abstract of the Disclosure A thyristor valve includes a plurality of thyristors connected in series and series circuits each including a capacitor and a resistor and connected in parallel with each thyristor.  A pulse from a pulse generator for firing the thyristors is applied to them at the beginning of a prescribed period of conduction of the thyristor valve when voltage across a selected one of the thyristors is forward.  An output signal of a current detector provides a firing pulse to all thyristors when the valve current exceeds a predetermined current value during the prescribed period of conduction of the thyristor valve.  In this way an overvoltage can be prevented from being applied to a specified one of the thyristors due to variations in the holding currents of the respective thyristors.          The arrangement is simpler in construction than prior art arrangements.

Abstract: Abstract of the Disclosure A fluid dispensing instrument and method for placing a drug material into the canals of the Fallopian tubes of a female.  The instrument has a housing carrying a piston and cylinder assembly.  An elongated flexible tubular probe attached to the housing carries an expandable sleeve.  The piston and cylinder assembly is operable to fully collapse the sleeve prior to insertion through the cervical opening into the uterine cavity.  After the sleeve is inserted into the uterine cavity, an ampulla storing the drug material is loaded into the instru-ment.  The piston and cylinder assembly is then actuated to ini-tially partially expand the sleeve.  Operation of the piston and cylinder assembly moves a plunger into the container to dispense the drug material into the uterine cavity above the partly ex-panded balloon.  The sleeve in then fully expanded to move the drug material from the uterine cavity into the canals of the Fallopina tubes.

Abstract: ABSTRACT           A method for removing residual oxygen from an aqueous slurry of pulp that has been oxygen-bleached is disclosed.  The slurry, usually containing no more than 3 weight percent fiber, is agitated by a radial-flow impeller, which imparts a substan-tially radial flow to the slurry.  If the residual oxygen is not removed, it may degas at an inopportune moment during later proces-sing (for example, washing) and carry some of the wood fibers to the surface of the slurry, thereby forming a foamy mat, which hinders further processing.

Abstract: ABSTRACT    A method is described for making molds for the casting of resin ophthalmic lenses having segments of prismatic optical effect. A first mold surface is formed in a first blank.   A second blank, having a recess therein shaped to the outline of the desired lens segment, is adhered to the first blank's mold surface.  A second mold surface is then formed in the blank resulting from the connection of the first and second blanks.  The first and second mold surfaces are each portions of surfaces of revolution having first and second axes of symmetry, respectively.  The second surface has an effective center of curvature on the second axis.  The second surface is so formed in the resulting blank that the first and second axes, if they intersect, do so at a location on the second axis other than at sub-stantially the center of curvature of the second surface.
