Abstract: ABSTRACT OF THE DISCLOSURE           A valve for use in a pressure differentially operated servo-motor to regulate the flow of fluid through a bore in a hub from first and second sources in response to movement of an input member by an operator.  The valve has a resilient disc member with a peripheral surface and a central opening.  First and second annular ribs symmetrically extend from opposite sides of the disc adjacent the central opening.  A spring connected to the input member holds the peripheral surface in sealing engagement with the hub.  In a first mode of operation, the spring holds the input member against the first annular rib to allow the fluid from the first source to freely communicate between first and second passages in the hub by way of the bore.  In a second mode or operation, the input member moves out of contact with the first rib; however, the internal resiliency of the disc and a pressure differential created across the disc between the first and second sources of fluid moves the first rib into contact with a seat in the hub to inhibit flow communication of the fluid from the first source through the bore while allowing the fluid from the second source to freely flow through the second passage to create the pressure differential from operating the servomotor.

Abstract: FAN-FOLDED LABELING TECHNIQUE            Abstract of the Disclosure Self-adhesive labels mounted on a backing strip are formed into fan-folded sets or stacks and are loaded directly from the fan-folding machine into an open four-sided cassette.  The cassettes are made of cardboard, and after they are loaded with fan-folded labels, they are enclosed either by the addition of a fifth side or by wrapping.  The cassette packages are then transported to the location where labels are to be-applied to products moving along a conveyor.  The fan-folded labels are supported in an open L-shaped rack which is tilted and which is of sufficient length to hold at least two sets or cassettes of fan-folded labels side by side.  The labels are fed directly into a standard type of label dispenser which applies the labels to products as they are moving along a conveyor line.  As labels are used up, the free end of the first stack of fan-folded labels may be spliced to the second stack of labels so that the high speed labeling machine does not have to be stopped for re-loading a fresh reel of labels, but the labeling process may continue without downtime.

Abstract: ?N 6835 FLUID JET DEVICE               ABSTRACT OF THE DISCLOSURE           A fluid jet device for depositing drops of  fluid  on  a  fluid  receiving  medium  includes  a print  head  means  which  defines  a  fluid  receiving reservoir   and   which   has   a   row   of   orifices communicating with the reservoir.  Fluid is supplied to the  reservoir  under  pressure  and  flows  through the orifices to produce a row of fluid filaments. The fluid filaments are stimulated to break up into jet  drop  streams  directed at  the  fluid  receiving medium.  The fluid in the reservoir is maintained at a    predetermined    electrical    potential.     An electrically   conductive  catcher   means   extends substantially  parallel  to  the  row  of  jet  drop streams  and  electrically  charges  the  drops  formed from each of the filaments when a charge potential, differing   from   the   predetermined   electrical potential  is  applied  to  the  catcher  means.   The charged drops are attracted toward the catcher means such  that  they  are  caught  and  prevented  from striking  the  fluid  receiving medium.   Drops  which are not charged by the catcher means travel past the catcher  means  and  are  deposited  on  the  fluid receiving medium.

Abstract: S P E C I F I C A T I O N          ___ Inventors:  HOWARD E.BORE,SR. and JAMES B. WILLIAMS Invention:  "MAT CLEANER"            Abstract of the Disclosure A rug or mat cleaning apparatus is disclosed which is comprised of first a dry lint and dust removing section, then a water or like liquid containing vessel having an initial wash section and then a rinse section and then finally a wringer section.  A mat to be cleaned is passed through a first conveying roller at a slower driving speed.  Thereafter, the mat or rug enters an increased speed brush which both removes dirt and agitates the surface of the rug and beats it to knock loose undesireable dirt and like particles.  In the wash section of the apparatus, alternating feed rollers and brush rollers carry the mat or rug to be cleaned. Each feed roller clamps and holds the rug to prevent slipping while conveying it at a slower linear speed.  Each brush roller provides a brushing surface having a substantially higher linear speed than the surface of the conveying rolls. Thus, a "tuck" or crease is created in the rug between each high speed roller brush and its adjacent and following slower conveying roll.  A wringer is provided at the end of the apparatus to remove extraneous water from the rug after its cleansing.  Pressure belts are provided above the cleaning brushes for enhanced cleaning and operation.  A special beater roller with projecting ridges is also included.

Abstract: ABSTRACT OF THE DISCLOSURE A universal signal translator for use in a speed control system for connecting a speed controller producing speed command output signals having a first range of volt-ages or currents, to a motor speed regulator designed to operate on a second, different range of input control vol-tages from a control potentiometer.  The signal translator can be  connected between the  speed controller and the motor speed regulator and will automatically couple con-trol signals from the controller to the speed regulator while automatically accommodating a wide variety of con-trol voltage ranges, without requiring any modifications or adjustments.  The translator provides output signals to the regulator proportional to the speed command signals from the controller and automatically scaled to the appro-priate voltage range of the regulator.  This permits a standard universal signal translator to be used with a wide variety of different makes and models of speed regu-lators, without requiring expensive engineering modifica-tions or redesign.

Abstract: IBM Docket No. BC 9-80-005 ABSTRACT OF THE DISCLOSURE An error correcting code mechanism for SEC-DED (16,  21) or (8, 12) code to correct data bit errors caused  by  alpha  particle  impingement  into  high density storage units.  The data word is read into and out of a high density storage unit and generated check bits are stored in low density storage immune to  alpha particle  radiation.   Data bits and check bits,  addressed in parallel are read out to error detecting and correcting circuits to determine the existence of an error only in a data bit and correct the state of the erroneous bit.  The number of check bits  and  required  parity  checking  circuitry  is reduced  since  no  error  checking  of  check  bits, presumed to always be correct because of the use of low density storage occurs.
