Abstract: ABSTRACT OF THE DISCLOSURE           An adjustable thermostat as disclosed having an adjustment stem journaled for rotation on the thermostat body for adjusting the operating temperature of the thermostat. Mounted on the adjusting stem is a pointer member formed of deformable material such as Nylon and providing a peripheral surface which engages with interference stationary surfaces on the thermostat body.  Interengagement is provided between the peripheral surface and the stationary surfaces which causes deformation of the pointer member and creates friction resisting rotation of the pointer and of the adjusting stem. A detent-like structure is provided by flats formed on the peripheral surface of the pointer which mate with the corres-ponding surfaces of the body to tend to lock the pointer and in turn adjusting stem at a predetermined temperature.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure is directed to a hand tool of the pliers configuration having a set of crimping nests located in jaw members and having the expansion zones of the crimping nests overlap so as to permit placement of each of the nests closer to the optimum distance from the handle pivot.  A visual indicator permits the operator to crimp terminals of different discrete sizes in a single one of the crimping nests and a device used to lock the handles in a closed position further provides discrete limits of crimping nest closure.  A compression spring located in overlapping slots of the handle member provides a recessed means to rapidly open the handles when the locking device is released.  The locking device includes a receiver in one handle and a lock and stop device in the other handle.  When the latter device engages the receiver the handles are locked together.          When the lock and stop device is positioned in other selected positions it bears against the one handle to limit closure of the handles and to hence limit the crimping action of the crimping nests.

Abstract: ABSTRACT OF THE DISCLOSURE           Beam sensing elements are located in a predetermined positional relationship with horizontally spaced color phosphor strips in a television screen.  Impingement of an electron beam upon the sensing elements produces an index signal representing the nonlinearity which may be present in the horizontal deflection waveform, the index signal being stored in a storage medium until the next raster scan and retrieved repeatedly at the start of each line scan.  The retrieved index signal is modulated in frequency with a signal representing the time it takes for the electron beam to traverse a single horizontal line to compensate for pincushin distortion.  The frequency modulated index signal is phase shifted to generate sampling signals for the primary color signals generating a dot-sequential video signal which is used to modulate the intensity of a first electron beam. A second electron beam is successively modulated in intensity and caused to impinge substantially on the same spot where the first electron beam has previously impinged.  A pair of horizontally spaced apart deflection plates is provided adjacent the electron beam sources to oscillate the electron beams in a direction parallel to the horizontal scan lines to increase the dwell time of the impinging electrons on a given beam spot to thereby increase its brightness.

Abstract: INVENTION:   CHAMBER SIDEWALL MOUNTED STIRRER              CONTINUOUS DISTRIBUTOR SYSTEM          INVENTOR:    WALTER KRAMER       ABSTRACT     An apparatus is disclosed for continuous distribution of at least one additive, in a particulate master or base material.  In the apparatus a rotary distributor disposed in a stationary chamber moves along a circular path in a substantially vertical plane that is normal to the horizontal axis of rotation of the distributor.  The particulate master is fed into the chamber through a first inlet arranged below the upper horizontal tangent line of the circular path of the distributor, while additive is fed into the chamber through at least one second inlet above the tangent line, the input flow rates and the output flow rate through an outlet in the bottom part of the chamber being so controlled as not to exceed a maximum charge level substantially defined by the above-mentioned tangent line and to form an inclined upper surface of the processed charge within the chamber for over-rolling movement of the particles of the master with concurrent interblending of the additive supplied onto the inclined upper charge surface.  The apparatus is particularly suited for continuously interblending a minor amount of at least one additive and a major or predominant amount of a master or base material of the type used in pastics processing, notably for coloring or the like modification of a plastics material or composition prior to extrusion or another plastics shaping operation.
