Abstract: ABSTRACT OF THE DISCLOSURE A method for forming a colored image in a limited area of a vision-corrective soft contact lens.  In one method, the lens is soaked in a diszonium salt and then exposed to actinic light through a mask which transmits light only to the non-imagc area of the lens.  Then, the unexposed image area is deve-loped by contact with an azo coupler. In a second method, the diazonium salt issoaked in a gel relief of the desired image configuration and contacted with the lens.  The image is developed by soaking in the azo coupler.  In a third method, the diazonium salt, azo coupler, and a coupling inhibitor (a pH reducingagent) are premixed and applied by the gel relief.  The image is then developed by raising the image pH level as by contact with ammonia gas.  Also, apparatus for precisely contacting the lens with the gel relief image.

Abstract: SLURRY PUMP TRAM CONTROL APPARATUS Abstract Method and apparatus are described for removing material from a sump.  The sump has substantially parallel and elongated sidewalls and has a longitudinal axis.  The sump is enclosed with ends and a bottom and is adapted for filling with a water-solid mixture to form a slurry.  A suction pump is mountad above the sump and extends into the sump for removal of the water and solid material.  Apparatus is attached to the suction pump for moving the suction pump along the longitudinal axis of the sump.  When the suction pump reaches the end of the sump, apparatus rotates the suction pump through 180 degrees and then the moving apparatus again moves the sump along the longitudinal axis to the other end where it is again rotated in the opposite direction through 180 degrees to the original point for repeating the process.

Abstract: A B S T R A C T    A method of recording information on a medium in the form of electrical signals comprises such opera-tions as application of a uniform thermal field and simultaneously or subsequently a uniform vector field to an area of a working area of the medium, vector li-nes of said uniform vector field being normal to the surface of the medium. At least one of said fields is produced by converting electrical signals conveying information. During recording in said area of the me-dium heated to a temperature above the softening tem-perature of a binder the particles are aligned along the vector lines of the field whereby optical density of said area of the medium is changed in accordance with the recorded information. The fixing is accomp-lished by cooling the medium below the softening tem-perature of the binder and is started after stopping the application of the vector field.

Abstract: MAGNETICALLY LATCHED ELECTRICAL SWITCH ABSTRACT OF THE DISCLOSURE In a switch, in particular a power, control or starter switch, a contact system and a magnetic system are provided in a housing whereby the magnetic system actuates the contact system. The contact system is provided with contact arm supports having rigid contact pieces, as well as actuatable bridges with movable contact arms which are actuated by means of a common contact operating and latching member, so that each bridge and the associated contact arm supports are mounted in a switch chamber. Furthermore, a switch-on contact with a self-locking contact is provided. In switches of this type, it is typically required to hold a switching operation for a longer time period, without necessitating the manually pushing down of a push key. The required separate switch-on contact is typically mounted in a separate large housing. In order to reduce the structural and space requirements and to permit a simple wiring, a contact is physically or structurally connected with the switch for the switch-on contact, which latter can be actuated from the outside by means of an actuating element, and which cooperates with the common contact operating and latching member.

Abstract: ABSTRACT OF THE DISCLOSURE         A proportioning valve for a vehicle hydraulic brake system has a lock out mechanism whereby the valve may be selectively rendered inoperative for given vehicle load con-ditions.  The valve has a piston responsive to hydraulic pres-sure, for operating the valve, a rotatable cam having a cam profile communicating with the piston, a rotatable shaft and a coupling between the cam and the shaft whereby rotation of the shaft, in response to vehicle load conditions, effects rotation of the cam, the cam profile being configured to impede movement of the piston when the cam is rotated to a given angular position, thereby locking the valve in an in-operative configuration.

Abstract: ABSTRACT            An apparatus for stirring a molten metal in an open topped mould, in for example a continuous casting process, including means positioned above the mould for producing a moving magnetic field which penetrates into the mould. The magnetic field may be produced by a series of electrical conductors which are positioned above the mould.  Each of these conductors are connected to a different phase of a multi-phase alternating current supply and are arranged relative to one another so as to produce a magnetic field which either moves linearly or rotates about the vertical axis of the mould. Ferromagnetic pole pieces may be associated with the conductors to provide a low reluctance flux path which will reduce leakage of the magnetic field above the conductors and concentrate the field below the conductors where it penetrates down into the mould.

Abstract: Improved Variable Area Two-Dimensional Converging/Diverging Nozzle Abstract A two-dimensional variable area convergent/ divergent exhaust nozzle having the capability for wide throat area variation includes upper and lower spaced apart flap means.  The upper flap means comprises an upstream converging flap having its rear edge hinged to the forward edge of a downstream diverging flap, wherein the nozzle is movable between  maximum and minimum throat area positions by actuation means which includes guide means, such as cam tracks, for guiding the forward edge of the upstrem flap to move downstream while simultaneously constraining both the upper flap means hinge joint and the rear edge of the diverging flap to move both downstream and closer to the engine axis.  This type of motion permits large changes in throat area with minimal increase in the slope of the diverging flap permitting use of a shorter diverging flap.  Preferably the forward and rearward edge of the converging flap move along circular arcs having the same center in order to minimize moments on the flap.
