Abstract: ABSTRACT OF THE DISCLOSURE          A system is described for interfacing a SWIF with a tuner and an amplifier in the IF section of a television receiver.  In the preferred arrangement, the tuner is coupled to the input of the SWIF so as to efficiently transfer signal power to the SWIF over the frequency range of the tuner's output.  The output of the SWIF is coupled to an amplifier which has a low, untuned input impedance to establish a mismatch between the SWIF and the amplifier to thereby reduce triple-transit effects associated with the SWIF.  Preferably, the amplifier is a common-base amplifier whose input impedance is defined by a real impedance component which is substantially smaller in magnitude than its reactive impedance component.  Hence, the real component of the amplifier's input impedance is dominant and the effects of stray capacitance between the SWIF and the amplifier are reduced.

Abstract: ABSTRACT                    Shaft Mucker A shaft mucker comprises a control cabin 1 carrying a boom 2 which can be luffed by hydraulic rams 4 between a raised horizontal position and a lowered downwardly extending position.  Suspended from the outer end of the boom 2 is a block 5 for carrying a rubble collector, preferably in the form of a pneumatically operated grab, -the block being suspended in such manner  that it remains level when the boom 2 is luffed.  Raising and lowering the block is effected by winching in or out the suspension rope 6 at one of its ends, the block carrying a hose reel 14 for automatically winding on and off a pneumatic pressure supply hose 13 for the grab as the block is raised and lowered.  On top of the cabin 1 the mucker has an overhead support assembly 47 by which the mucker can be suspended from a hoist  or supported by a sinking stage,and which has a slewing ring 48 so that the cabin is rotatable about a vertical axis to slew the boorn.  To assist the mounting of the rnucker beneath a sinking stage the support assembly has a pair of arms 52 which are pivotally connected at one end 53 near the edge of the slewing ring and which haves rest position in which they extend across the top of the assembly 47.  The mucker is lowered through an opening near the edge of a sinking stage by means of a hoist rope attached to the support assembly 47 and 59, and the free ends 54 of the arms 52 are engaged with hooks on the sinking stage.  Further lowering of the mucker causes the arms 52 to pivot upwards into a vertical position and the cabin 1 together with the boom 2 to swing inwards beneath the sinking stage towards the centre of the shaft.  The boom is then raised slightly to change the centre of gravity of the mucker sufficiently to right the cabin 1 and bring eyes 56 of the rnounting assembly 47 into registry with corresponding eyes on the sinking stage, and insertion of retaining pins through the eyes completes the mounting.

Abstract: "ROUND BALE HOLDER FOR FRONT END LOADERS" ABSTRACT OF THE DISCLOSURE          When moving relatively heavy round bales of hay and the like, from one location to another, it is desir-able to replace the bale back on the ground so that the previous portion of the circumference that was in contact with the ground, again contacts the ground to prevent additional weathering or deterioration of the bale from taking place.  Many conventional bale moving devices can-not maintain this positional integrity.  The present de-vice can be attached to a front end loader frame or a three-point hitch device and consists of the vertical frame having adjustable connecting plates thereon and a pair of bale engaging prongs extending forwardly therefrom in spaced and parallel relationship so that they may engage a bale, lift it for transportation and then replace it in exactly the same relationship at the new location.  The bale prongs are socketed into the frame and held by clamp bolts which may act as shear bolts and eliminate the deter-ioration of surrounding material which occurs when such prongs are welded into position.

Abstract: ABSTRACT For a dynamic balancing machine the values of parameters employed to determine the weight, rim spacing and diameter of a wheel are automatically entered into the balancing machine by a single maneuver of an extensible wand. This simplicity eliminates many opportunities for human error when obtaining the same information otherwise.  The wheel balancing machine is of the type having a frame, a device for rotating a wheel to be balanced and a computing device for carrying out calculations, determining the value of a radius of the wheel and determining the distance between the wheel and the machine based on the values of inputs supplied thereto.  The extensible wand for entering parameters into the computing device comprises an arm extending between the periphery of the wheel and a point located a predetermined distance from the axis of rotation.  The arm defines a ~irst side of a triangle and the predeter-mined distance defines a second side o-f the triangle.  A slide pushes the arm a measurable distance so ~hat the arm rests in contact with the wheel and a sensor carried by the frame senses the value of the angle between the two sides of the triangle and the value of the measurable distance.  Signals representative of these values are transmitted to the computing device.
