Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus adapted for cooperation with the human foot for performing a switching function in response to ambulation.  A substrate is provided with a generally cen-trally located contact.  Posts extend from the substrate and space a flexible disc from the contact while allowing the central portion of the disc to flex into electrical com-munication therewith.  The assembly may be positioned in the heel portion of a shoe insole so as to switch between open and closed positions as weight is placed on the heel and re-moved, as in walking.  The switch may be employed in as-sociation with muscle and/or nerve stimulators for objectives such as combating foot drop or providing hip stabilization. In addition, proper selection of the flexible disc and post spacing will provide a normally open switch which will close when a preselected limb load has been applied.  Also, the apparatus may be made bi-directional such that the same insole assembly may be employed with either foot.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for cleaning the exhaust gas of a high-pressure blast furnace comprises an optional coarse-particle separa-tor, a prewasher and a differential-pressure annular gap washer tra-versed in succession by the gases.  The exhaust gases can be passed through a main duct provided with an expansion turbine or through a bypass duct around the expansion turbine.  The expansion turbine unit controls the back pressure at the blast furnace while a separate con-trol circuit is provided to operate the differential-pressure washer with optimum efficiency.  A quick-closing valve in the turbine-supply line and a quick-opening valve in the bypass line permits rapid switchover, a pressure-control valve in the bypass line maintaining a constant backpressure at the blast furnace when the expansion tur-bine unit is shut down.

Abstract: ABSTRACT OF THE DISCLOSURE   color television receiving apparatus is disclosed in which a chrominance signal passed through a band-pass amplifier is applied through a first variable gain control circuit and through a second variable gain control circuit to a color demodulator cir-cuit. When a received composite color television signal includes a vertical interval reference (VIR) signal, the first variable gain control circuit is controlled in its gain in response to the amplitude of the VIR signal obtained from the chrominance signal that is passed through the first variable gain control circuit. thereby automatically correcting the color saturation level to be constant.          When the received composite color television signal does not include the VIR signal, the gain of the first variable gain control circuit is made constant. The gain of the second variable gain control cir-cuit , irrespective of the presence or absence of the VIR signal , is changed by a common adjusting volume control. thereby enabling the color saturation level to be preferentially adjusted.
