Abstract: Abstract A mobile  offshore  platform  has  a  buoyant  and bal-lastable mat  base  of  substantial  horizontal  extent.   A cylindrical pylon is fixed to and extends upwardly from the center of the base.  The pylon has a height greater than the maximum  operating  water  depth  of  the  platform.   A positively buoyant deck unit has a central opening through it within which the pylon cooperates.   The deck unit  is movable vertically  along  the  pylon  in  response  to  the operation of  jacking  mechanisms  and  cooperating  jacking legs located adjacent the corners of the deck unit.  The jacking legs are engageable at their lower ends with the base whereby operation of the jacking mechanisms causes the deck unit to be moved vertically along the pylon relative to the base.  In use, the deck unit is elevated to the top of the pylon after the base is submerged into contact with a sea floor and the jacking legs are thereafter disposed in a retracted position  with their lower  ends  adjacent  the deck unit.   In use,  the deck unit  is disposed above the water surface.  The platform is especially suited for use in ice-covered waters on the margins of the Arctic Ocean.

Abstract: ABSTRACT OF THE DISCLOSURE          An AFC circuit is employed in a television signal receiving apparatus which comprises a tuner having a local oscillator and a mixer for mixing a received high-frequency video signal and an output local oscillation frequency signal of the local oscillator so to frequency-convert the received high-frequency television signal to an intermediate frequency signal, and a tuning voltage generating circuit for generating a tuning voltage responsive to a desired receiving channel which is selected so as to apply the tuning voltage to the local oscillator of the tuner.  The AFC circuit comprises a frequency discriminating circuit for frequency-discriminating an output intermediate frequency signal of the tuner, a lowpass filter supplied with an output signal of the frequency discriminating circuit, and a limiter circuit supplied with an output signal of the lowpass filter, for limiting the voltage level or the output signal of the lowpass filter depending on the desired receiving channel.  The local oscillator receives an output signal of the limiter circuit. The limiter circuit performs a limiting operation in each receiving band when receiving a channel in which a change in the local oscillation frequency is large with respect to a change in the tuning voltage.

Abstract: Title:       "Wall Washing Pad Holder"     ABSTRACT OF THE DISCLOSURE Pad holder includes a generally flat rectangular mounting plate or head having a front or bottom side to which the pad is attached and a top or back side having a plurality of spaced-apart ribs thereon terminating in a common plane substantially parallel to the planar bottom side of the mounting plate to provide for the transfer of pressure from the wringer plates of a conventional mop wringer to the pad through the ribs to squeeze out the pad. The ribs provide for the recess mounting of a hinge member to the back side of the mounting plate. The hinge member permits a handle socket connected thereto to be pivoted up against the back side of the mounting plate below the tops of the ribs where it will not interfere with the pressure engagement of the wringer plates with the ribs and pad, respectively, during wringing out of the pad. The ribs are preferably open or slotted at least at one end thereof to permit water to flow freely between the ribs and back into a mop bucket or the like as the pad is being wrung out.

The bolt assembly includes a bolt having a head portion (40), a threaded end portion (42), a shank portion (44) between the head portion and the threaded end portion and a spring pin (46) surrounding the shank portion. The spring pin is generally tubular with a slot (48) extending the full length thereof, and is desirably held captive on the shank portion. When assembled, the spring pin (46) presses tightly against a bore (26) through one part (14) and also against a coaxial bore or counterbore (28) formed in another part (12) so as to maintain the parts in accurate alignment. The spring pin may have a length greater than the depth of the bore (26) through the one part (14) and less than the combined depth of the bore (26) through the one part and bore or counterbore (28) in the other part (12) so that it is assured that the spring pin crosses the parting line (32, 34) between the two parts when the bolt is tightened to the desired extent. Alternatively, the length of the spring pin (46) could be reduced by captivating the spring pin in a desired location along the length of the shank portion (44).
