Abstract: A B S T R A C T    Electrographic apparatus includes a transducer pad having a flexible membrane mounted over a base member with facing surfaces of the membrane and base member being electrically conductive and having electrical voltages applied thereto whereby to provide electrical signals representing the coordinates of a location at which pressure is applied to the flexible membrane locally by a pen or stylus, wherein in order to maintain an appropriate tension in the flexible membrane, the membrane is attached to and mounted on an outwardly tensioned rectangular frame member.          The frame member may comprise separate frame elements and spring members forcing the elements away from one another.          Alternatively, the frame member may be resilient and be inwardly compressed during the attaching thereto of the flexible membrane whereby the inherent resilience of the frame member subsequently tensions the flexible membrane.

Abstract: ABSTRACT OF THE DISCLOSURE     A material transport and self-unloading vehicle having an open top hopper for accommodating bulk material, as animal feeds. A first material conveying auger is located along the bottom of the hopper for moving material toward a side discharge opening in the hopper.  A second paddle auger is located above the first auger for moving material rearwardly in the hopper.  A side un-loading conveyor mounted on the side of the hopper adjacent the side discharge opening operates to receive material moved through the discharge opening by the first auger and move the material laterally of the hopper to a discharge or feeding location.  A drive assembly drivably connects a power take-off drive shaft to the first and second augers and unloading conveyor for con-current operation of the augers and unloading conveyor.  The bottom wall of the hopper has a curved section extended contigu-ously around the leading section of the flights of the first auger and a linear bend or break line located adjacent the lead-ing side of the first auger in a horizontal plane that generally intersects the axis of rotation of the first auger.

Abstract: LOW PROFILE MINING MACHINE     Abstract of the Disclosure -To maintain the lowest possible machine profile be-tween the bottoms of the crawler treads and the top of the turret, the boom of the machine and boom lifting cylinders are cantilevered forwardly of the turret and depressed to lie as closely as possible to the underlying gathering head of the machine without clogging the throat of the machine and/or inter-fering with the operation of the gathering arms.  The boom pivot and boom lift cylinders are disposed ahead of the crawler treads and the connections of the boom lift cylinders with the turret are forwardly of the highest part of the gathering head.  This geometry renders it possible to significantly lower the eleva-tion of the machine turret on which the boom is mounted for sluing or swinging movement and thus minimize the total height or profile of the mining machine.

Abstract: FAST-FILL MASTER CYLINDER                       ABSTRACT OF THE DISCLOSURE         A master cylinder includes a housing defining a reservoir and a bore for movably receiving a pair of pistons.  A primary piston cooperates with a secondary piston to define a primary chamber there-between and cooperates with the housing to substantially define an auxiliary chamber.  The primary chamber and auxiliary chamber are disposed within a substantially uniform diameter section of the housing bore.  The primary piston is movable within the bore to com-municate fluid pressure from the auxiliary chamber to the primary chamber until a predetermined pressure level  is reached in the primary chamber whereupon the auxiliary chamber is vented to the reservoir.          A sealing member disposed within a recess on the bore cooperates with the piston to define the auxiliary chamber.  Upon initial movement of the piston relative to the sealing member, a small portion of the fluid within the auxiliary chamber is communicated to the reservoir so as to bleed the auxiliary chamber.  Further movement of the piston relative to the sealing member closes the auxiliary chamber to the reservoir and communicates pressurized fluid from the auxiliary chamber to the primary chamber.  The sealing member is disposed within a recess on the wall of the housing bore and the recess leads to an opening communicating with the reservoir.

Abstract: AN ELECTRICAL FUSE HOLDER          ABSTRACT OF THE DISCLOSURE       A fuse holder for a miniature cartridge fuselink, comprises a hollow body and a fuse carrier, formed as plastic mouldings, and two spring metal contact members engagable with the outside of the body and having con-tral parts which project into the cylind  cal chamber of the body through slots in the body wall.  The con-struction is such that the fuse carrier can only be inserted into the body when it is oriented in one pre-determined position relative to the body and, in this position, there are barriers of insulation material between the end caps of a fuselink snapped into the fuse carrier and the potentially live electrical terminals on the body.  When the fuse carrier is fully inserted into the body, it can be rotated through one half turn to engage the end caps of the fuselink with the contacts. The fuse holder prohibits a user from touching any live terminals, and the end caps of the fuselink cannot engage the contacts of the holder whilst the fuse carrier is being inserted into or removed from the holder.

Abstract: LOW-MOISTURE, FRANGIBLE AERATED CONFECTIONS                   AND METHOD OF PREPARATION                  ABSTRACT OF THE INVENTION Disclosed are aerated, dextrose-based confections and methods for their preparation.  The confections essentially comprise from about 87% to 99% dextrose, from about 0.5% to 3% whipping agent and from about 0.5% to 7% moisture.  In one method for making the confection, a confection melt is pre-pared from melted dextrose monohydrate and a whipping agent such as hydrated gelatin.  The confection melt of specified temperature range (190°F. to 270°F.) is pumped through a whipper so as to aerate the mixture to particular densities (0.2 to 1.0 g./cc.).  The composition is simultaneously cooled to achieve particular whipper exit temperatures (160°F. to 220°F.).  The aerated confection is then formed into pieces of desired shape and size and thereafter cooled.  One embodi-ment of the aerated confection is suitable for use as black-board chalk.

Abstract: ABSTRACT      A method and apparatus for gaging the cross-sectional bore diameter generated by an abrading type finishing tool in an abrading machine.  The tool and plug gage are mechanically mounted to the same spindle with the plug sized to a predetermined diameter and mounted behind the machining element.  The plug gage is indexed to enter the bore being machined at predetermined cycles to determine if an undersize condition of the tool exists.  Failure of the plug gage to enter the bore would indicate an undersize condition of the tool and upon the gage entering the bore it would indicate a correct tool size.  The invention has further means for shutting down the machine in the event an undersize condition is determined.

Abstract: ABSTRACT METHODS OF PRODUCING IMAGE INFORMATION FROM OBJECTS To produce image information from an object it is subjected to a continuous static magnetic field along a Z axis and to sets of sequences of orthogonal gradients Gx, Gy and Gz to the magnetic field.  Spins in a selected plane (the X-Z plane) are excited by selective rf pulses and an associated Gy gradient and the selected spins are subjected to all three gradients of which the Gz gradient provides twist or warp to each column of spins extending along the Z axis to phase-encode the columns.  The spin-echo signals are read out in the presence of a Gx gradient.  In each set of sequences a different value of Z gradient is employed.  The Fourier transformed spin-echo signals obtained from each sequence, when arranged in order of increasing G  gradient and subjected to a second Fourier transform represent the distribution of spin density in the Z direction, thus giving a two-dimensional image of the selected X-Z plane.
