Abstract: ABSTRACT     A cover assembly is provided to be secured to the upper end of an exhaust pipe of an internal combusion engine maintained outdoors in such a manner such that a cap forming part of the assembly will cover the end of the exhaust pipe when the engine is quiescent.  When exhaust gases exert pressure in the pipe during operation of the engine the cap will be raised against gravity off the end of the pipe to permit the gases to escape.  The movement of the cap between open and closed positions is a rocking movement about a pivot and normally results in considerable clatter as the parts strike metal.  Means are provided by the invention to reduce the clatter.

Abstract: BORE HOLE MINING     ABSTRACT OF THE DISCLOSURE     Minerals, in particular coal, that have been deposited in layers or along seams in the earth can be mined utilizing large diameter bore hole drilling equipment.  With the drilling equipment stationed on the surface of the earth, a drilling member is drilled down into the earth along the seam of the mineral deposit.  If the mineral deposit extends at an angle to the earth, i.e. less than 90°, the drilling operation is conducted so as to drill at a similar angle to the earth.  As the mineral deposits are broken up during the drilling operation, the broken fragments are removed from the drilled hole.  After drilling has occured for a certain distance in a forward direction, a creeping effect is induced in portions of the side walls of the drilled hole.  The drilling member is then retracted from the drilled hole in such a manner so as to drill out any mineral fragments in the hole of the drilling member.  These mineral fragments are then removed from the hole as the drilling member is retracted.  The removal of the mineral fragments can best be accomplished utilizing an hydraulic flow mechanism for circulating fluid through the drilling member and removing the mineral fragments as they are drilled.

Abstract: ABSTRACT OF THE DISCLOSURE The IF section of a television receiver includes an amplifier having an input terminal for receiving an IF signal and an output terminal at which an amplified version of the IF signal is developed and a SAW filter having two input terminals for receiving the amplified IF signal, one of the input terminals being connected to AC signal ground and having an output terminal for providing a modified IF signal having a bandpass characteristic determined by the SAW filter. An impedance transformation network is coupled between the output terminal of the amplifier and the input terminal of the SAW filter for increasing the effective load impedance of the amplifier and for decreasing the output impedance of the drive arrangement. The former aspect of the impedance transformation network allows a transistor with lower current supplying capabilities to be employed. The latter aspect of the impedance transformation network tends to reduce undesired voltages developed in response to reflections between the transducers of the SAW filter. Specifically, the impedance transformation network includes an inductor connected between the output terminal of the amplifier and the AC signal ground, a capacitor connected between the output terminal of the amplifier and the input terminal of the SAW filter and a resistor connected between the input terminal of the SAW filter and the AC signal ground. Desirably, the capacitance of the capacitor is in the same order of magnitude as the input capacitance of the SAW filter and the inductance of the inductor is selected to provide a resonance with the effective capacitance in the passband.
