Title: Pea separating apparatus and method of use
Inventor: ADAMS TIMM L
IPC: B03B5/62
Filed: 1991-06-19
Granted: 1995-10-31
Abstract: An apparatus and method for separating peas based upon differences  in density.   The  apparatus includes a flow trough having a flow manifold.  A pump takes water from a reservoir and delivers the water to the flow manifold.  A flow nipple having a lip portion extending into the flow manifold and turning vanes within the flow manifold distribute the water to create a substantially laminar flow.  Fixed and pivotable water deflectors at an inlet portion of the flow trough establish a linear, laminar flow of water along the flow trough.  A hopper and conveyor combination deliver a stream of peas to an adjustable plate member positioned in the laminar flow of water in the flow trough.  The peas carried by the laminar flow of water descend off of the plate member into a separating chamber where peas having  a  high  density  range  settle  into  a  first collecting chamber and peas with a low density range settle into a second collecting chamber.  A adjustable separating  vane  separates  the  first  and  second collecting chambers and together with the plate member is  adjusted to  accommodate  batches  of  peas  having differing density characteristics.

Abstract: In  a  bowling  game,  an  apparatus  to  automatically retrieve knocked down tenpins from the skittle alley,  after each ball strike  aimed thereat.   The  apparatus includes a series of cables each connected to the head of a  corresponding one  of the tenpins.    The  cables  are  connected  to a computer controlled slider, guidingly carried by a horizontal  rail and  power driven in reciprocating  motion by  an endless  belt.  Once at least one tenpin is struck by a  ball,  all  tenpins  are  lifted  by their cables through actuation of the motor of the power driven endless belt.   The slider  then returns  to its  initial position, which will enable  the cables to yield to the weight bias of their pins and therefore allow all of the latter - but for  the knocked down tenpin - to fall back to their upstanding position on the skittle alley.  The knocked-down  pin  has  been  identified  by optical sensors  connected  to  the  computer, and the computer will have actuated a cam-type cable lock to prevent release  of the knocked down pin cable under the weight of this latter pin.

Abstract: The quality of glued nested paper towels is improved by embossing at least one of the two plies using a matched rubber embossing roll and applying adhesive to that embossed ply using a rotogravure printing roll while the ply is backed by the matched rubber embossing roll. The use of a matched rubber embossing roll reduces strength degradation of the ply during embossing and permits the use of rotogravure adhesive printing, which provides metered application of adhesive with less adhesive strike-through.

Title: Arrangement for measuring mechanical properties of a foil material
Inventor: PETTERSSON THORULF
IPC: G01N33/34
Filed: 1991-03-21
Granted: 2001-07-17
Abstract: An arrangement for measuring mechanical propert-ies of foil material (10), prefer-ably paper. The arrangement includes a material excitation unit (12) and a material sen-sing detection unit (14). The two units are connected electri-cally to a common arithmetical unit (18). This unit is intended to register and convert electri-cal signals deriving from the two first mentioned units (12, 14) in a manner to produce fi-nal signals which represent the material properties to be mea-sured. The excitation unit (12) includes a laser which, through electromagnetic radiation, is intended to generate in the gaseous atmosphere surround-ing the material local transient gas-pressure pulses within var-iable surface zones which are well-defined geometrically, without the excitation unit coming into contact with the material. These gas pressure pulses cause the material (10) to stretch locally in the boundary regions of the zones, such stretching of the material being necessary to the measur-ing process. The detection unit (14) senses this stretching of the material, without coming into contact with the material, by detec-tingtransient changes in these material zones.

Abstract: On time division multiplexing first through N-th input signals, each having a bit rate V to represent successive ATM cells, a multiplexing section (12, 13') multiplexes the first through the N-th input signals and a dummy input signal into a time division multiplexed signal having another bit rate V x (N+l) and comprising first through N-th multiplexed cells and a dummy multiplexed cell.  The first through the N-th and the dummy multiplexed cells are derived from the first through the N-th and the dummy input signals, respectively.  A controller (16') successively writes valid cells of the first through the N-th multiplexed cells in an FIFO memory (15) as written cells at a writing rate equal to the bit rate V x (N+l) for a writing time interval defined by the first through the N-th multiplexed cells and reads the written cells from the FIFO memory in a first-in first-out order as a read-out signal at a reading rate equal to the bit rate V x (N+l) for a reading time interval defined by the dummy multiplexed cell.  A converter (17) converts the read-out signal into a multiplexed output signal having the bit rate V.

Abstract: Déstabilisation métabolique d'une protéine ou d'un peptide d'intérêt in vivo. La protéine ou le peptide d'intérêt contient un deuxième déterminant du signal de dégradation basé sur la règle de la terminaison N. Les procédés de la présente invention comprennent la mise en contact de la protéine ou du peptide d'intérêt avec la protéine ou le peptide cible qui interagit spécifiquement avec la protéine ou le peptide d'intérêt. Le peptide ou la protéine cible contient un aminoacide à terminaison amino déstabilisant selon la règle de dégradation des protéines de la terminaison N, mais ne possède pas un deuxième déterminant du signal de dégradation basé sur la règle de la terminaison N. Ces procédés requièrent cependant l'identification d'un peptide ou d'une protéine qui interagit spécifiquement avec la protéine ou le peptide d'intérêt. Etant donné que presque toutes les protéines interagissent spécifiquement avec d'autres protéines, ce procédé trouve une application étendue dans la déstabilisation métabolique in vivo d'une protéine ou d'un peptide d'intérêt.

Abstract: Faithful  color  images  are  created  in  an  efficient manner  for  display  on  a  specific  computer  display.   A standard computer  system generates  a palette calibration table, based on information about a standard display.  The standard computer system then creates a device independent image  from  the  palette  calibration  table  and  from  an original image.   The palette calibration table and device independent  image  are  then  transmitted  to  a specific computer system.  The specific computer system receives the palette calibration table and device independent image from the  standard  computer  system.  It  calculates  a  display specific palette from the palette calibration table and from information  about  the  specific  display.   The  specific computer system then generates the faithful color image for display by sending the device  independent image  and the display  specific  palette  to  the  display  adapter  in the specific computer system.
