Abstract: STABILIZED BIAS SYSTEM FOR MAGNETIC TAPE READ AND WRITE HEADS             ABSTRACT OF THE DISCLOSURE           A bias system for high speed tape recorders, typi-cally comprising a master reproducer and several slave re-corders  with  each  slave  recorder  having four recording amplifiers for driving the four heads of a four-track re-corder.   The master reproducer includes  a high frequency oscillator with an amplitude control,  a stable dc source with an amplitude control, and a summing network for com-bining the ac and dc signals to produce a master control signal for each of the slave recorders.  Each slave recorder includes a separator for receiving the master control signal and producing a dc signal and a high frequency ac signal. The dc signal is connected to each recorder amplifier for controlling the amplitude of the ac bias to the head.  The ac signal is used to synchronize the high frequency bias ac from the bias generator, which is combined with the audio information signal at each recorder amplifier and then con-nected to the record head.  Preferably each recorder ampli-fier is also provided with an independent amplitude control for matching the recorder amplifier to the particular record head.

Abstract: ABSTRACT         Disclosed is a system for measuring cell potentials in an aluminum potline having a plurality of cells connected in series.          The system enables better control of the cells than the current method which calculates cell resistance on the basis of measured cell potentials and potline current but an assumed value of back e.m.f.  The present invention uses corrected voltage measurements and provides a decentralized, current independent cell potential measuring system which converts simultaneously all cell potentials during a nominal integration period (e.g. 1 second) into a value corresponding to the potline current when it is at its normal (set-point) value.  Simultaneously, various possible back e.m.f. values are measured with the same current relationship and compu-tations made of the error caused by the non-ohmic portion of the cell potential when the current deviates from its normal (set-point) value.  Sudden changes in current enable correct values of back e.m.f. to be determined.

Abstract: ABSTRACT           This invention relates to a novel disposable "drink through" cup lid used as a friction fit closure for open mouthed containers.  The cup lid is provided with a central disc portion and a peripheral cavity portion which has an outer annular depending skirt for engagement with the cup rim.  Two spaced apart notches are located on the lowermost extremity of the depending skirt within a quadrant of the cup lid.  A pair of first and second fracture lines on the central disc portion extend interiorly of the disc from spaced apart points within the quadrant and which are in radial alignment with the notches.  Alternatively, or in combination with the first and second fracture lines, a single fracture line can also be located within the central disc portion where it is substantially parallel to a chord described between the notches.  The "drink through" or tear-away segment is removed by upward thumb pressure being applied between the notches.

Abstract: Abstract A method of making a gasket by pressing particles of expanded graphite in a mould onto the opposed faces of an apertured reinforcement plate to compact the particles and unite them with the plate makes use of a mould assembly comprising a base plate, first and second moulding rings, and a moulding punch which is apertured to conform with the apertures of the reinforcement plate.            The first and second moulding rings are positionable above the base plate to form lower and upper mould recesses, into which expanded graphite is sucessively charged, so enclosing the apertured reinforcement plate. The punch is then operated to compact the graphite particles and unite them with the reinforcement plate. Compaction in the mould assembly can produce either the finished gasket or at least a composite whose graphite layers are firm enough to be handled outside the mould assembly to permit further compaction.         The method is specially applicable to the manufacture of cylinder head gaskets for internal combustion engines.

Abstract: "BANDING KNIFE APPARATUS"       ABSTRACT       The  present  invention provides a new branding knife  apparatus  which  facilitates  the  burial  of  seed and fertilizer in soil during agricultural operations. The  banding knife apparatus disclosed has a forwardly disposed knife blade of narrow width with an upwardly disposed  transverse  fastening  device  which  does  not add  width  to  the  lower  portion of  the  knife  blade. The  knife  blade  can  be  removed  and  replaced  on the banding  knife  blade  holder  while  the  banding  knife blade  holder  remains  fastened  to  a  cultivator  shank with seed and fertilizer hoses in place.   Most banding knife  apparatus  of  the  type  having narrow blades  do not  permit quick changing of worn knife blades.   The use  of  this  banding knife  apparatus  thus speeds  and simplifies  the replacement of the cutting knife blade while providing a knife blade apparatus with a narrow cutting edge.

Abstract: ABSTRACT       The invention relates to an apparatus and a method of manufacturing a tampon, to the essentially cylindrical circumferential surface of which a liquid-permeable, thermo-plastic material is fastened, with the application of pressure and heat.  The dome-like construction at the introduction end and the withdrawal end of the tampon remain free of the liquid-permeable, thermoplastic material. The fastening of the liquid-permeable material to the outer surface of the absorbent material of the tampon, which consists of a nonwoven ribbon section rolled up on itself and pressed radially to give the fianl form of the tampon, guarantees that the high absorbency of the nonwoven fibre material, based on capillary action, continues through the liquid-permeable, thermoplastic material  onto its outside.          In addition, the liquid-permeable material offers protection against fibres becoming detached and makes it easier to introduce the tampon into and remove it from the body cavity.
