Granted: 1997-02-04
Abstract: Disclosed are the N, N'-(1-oxo-1,2-ethanediyl)-bisaspartates, methods for their preparation (including an unexpected preparation from glyoxal bisulfite and aspartic acid in concentrated aqueous alkaline media) and useful compositions containing the same; illustrative are general-purpose sequestrant compositions, chelating agent compositions for transition metals such as iron, manganese and copper,  general-purpose laundry detergent compositions and detergent compositions comprising perborate bleach, a bleach activator and, as a bleach stabilizer/performance enhancer, the novel bisaspartates.  These unique nonphosphorus compounds are useful  at low levels and differ from traditional -N-C-C-N- chelating agents such as ethylenediaminetetraacetates by the presence of one amino- and one amido- functional group which it is believed will provide additional advantages, such as improved biodegradation.

Inventor: MAILLOT CHRISTIAN
IPC: G11B7/0065
Filed: 1991-05-01
Granted: 2001-10-30
Abstract: L'invention concerne un système d'enregistrement do données sur disque optique,  Les disques optiques actuels, lisibles avec des lasers de longueur d'onde visible (entre 0,5 et 0,8 microns) ont une densité de stockage en surface qui est au maximum de l'ordre de un bit de donnée par zone élémentaire de surface d'environ 1 micromètre carré. Au dessous, la diffraction ne permet pas de distinguer des zones voisines.  L'invention propose un moyen pour augmenter considérablement les capacités de stockage : on inscrit dans une zone élémentaire (14) d'une couche (16) un bit d'information non pas sous forme d'un point d'absorption d'une lumière laser, mais sous forme d'un réseau diffractant ayant un pas déterminé.  Plusieurs réseaux diffractants de pas différents les uns des autres peuvent être superposés au même point, permettant l'inscription en une même zone du disque de plusieurs bits d'informations. Les réseaux diffractants sont réalisés par une variation locale périodique de l'indice optique de la couche. Ils sont réalisés par un faisceau laser d'énergie élevée, dans un matériau dont l'indice peut varier en fonction de cette énergie.  La lecture s~ fait par un laser (22) accordable en fréquence qui permet de détecter, pour différentes fréquences, la présence ou l'absence de réseaux diffractants.

Filed: 1991-07-02
Granted: 1997-02-25
Abstract: In  the  continuous  conching  of chocolate mass in a conche (10) it is important to  ensure  essentially  constant  con-tents  of  the  conche (10). For this purpose, the infeed of starting  material  and/or  the  discharge  of  the  conched chocolate  mass is monitored, namely measured, especially by means of weighing. In response to the  measurement  results, the  infeed  or  the  discharge is controlled, especially by means of altering the conveying  capacity  of  a  compulsory conveyor  (screw  conveyor  21)  for discharging the conched mass. The conched chocolate mass is dry,  i.e.  it  contains neither  lecithin nor cocoa butter. Lecithin is added in the region of the screw conveyor (21) which  is  followed  by  a mixing device (22).

Title: Managing high speed slow access channel to slow speed cyclic system data transfers
Inventor: BEARDSLEY BRENT CAMERON
IPC: G06F3/06
Filed: 1991-07-10
Granted: 1996-03-05
Abstract: A cached DASD controller is illustrated which is attached to a high  speed  serial  channel,  such  as  an  optical  fiber channel.   The  data  rate  of  the  serial  channel  is  much greater than the data  rate  of a DASD connected to  the controller.   The  serial  channel  has  a  relatively  long propagation time such that synchronous operations between the host processor 10 and the DASD cannot be efficiently performed.   Operation of a data transfer, whether read or write  between  the  host  processor  10  and  the  DASD  is monitored.   Whenever a copy of the track contents and in cache and the DASD reaches either an index mark with or a break point from a roll mode operation or certain write operations  occur  resulting  in  predetermined  data  being stored in cache,  then a GOCACHE flag is set in a control portion of the controller.  The device operations are then momentarily idled while cache to host processor operations are enabled.

Title: Method of bending a laminate having a thermoplastic core layer and metal sheets on each side
Inventor: BAARTMAN REINIER
IPC: B32B15/08
Filed: 1991-09-30
Granted: 1995-02-07
Abstract: Bending a laminate having a thermo-plastic core layer and metal sheets adjoining the core layer on both sides, is performed by heating the laminate and then bending it.  To allow bends of small radius to be made, heating causes softening of at least one of the boundary regions of the core layer adjoining the metal sheets, while a central region of the core layer remains unsoftened.  The heat may be by inductive heating of one or both metal sheets.

Title: Write laser power setting device and method
Inventor: MASUDA WATARU
IPC: G11B7/126
Filed: 1992-03-17
Granted: 1997-10-14
Abstract: A device for setting a write laser power for writing data on a recording medium includes first and second oscillators for producing carrier signals having high frequencies f1 and f2.  The carrier signals are added to produce a sum signal that is applied to a driver for producing a laser drive signal.  The power of the laser drive signal is changeable among various levels.  Using the laser drive signal, a write/read head writes test signals at preselected areas on the recording medium with different writing power levels applied to different preselected area.  After writing the test signals, the head reads the recorded test signal.  From the read signals, an unwanted signal having a frequency f1-f2 is filtered, and the level of this unwanted signal is detected and stored.  A minimum value of the stored levels is selected, and the area at which the minimum value was obtained is detected.  The writing laser power is then set at a level corresponding to the level used for writing the test signal in this detected preselected area.

Title: Strapping head with strap tail-flattening capability
Inventor: BOBREN ALLAN J
IPC: B65B13/34
Filed: 1992-04-06
Granted: 1995-10-17
Abstract: In a strapping head, slitting dies and a slitting punch on a punch holder cooperate to make a sealless connection in two overlapped layers of a tensioned loop of steel strap.  A sealing yoke moves the punch holder via a connection allowing lost motion between the sealing yoke and the punch holder.  A strap cutter on a cutter holder and an anvil cooperate to cut an outer layer of the tensioned loop.  The sealing yoke moves the cutter holder via a connection allowing lost motion between the sealing yoke and the cutter holder. A spring member biases the strap cutter in a forward direction, via a plunger engaging the strap cutter upon forward motion of the sealing yoke for a sufficient distance to take up lost motion between the sealing yoke and the cutter holder, whereby overtravel of the strap cutter flattens the strap tail.

Patent CA-2093670-C (CA)
Inventor: GEARY JAMES EDWARD JR
IPC: D04H1/54
Filed: 1991-10-29
Granted: 2003-08-19
Abstract: A method of preparing porous fiber reinforced polymer composite sheets has been developed to allow a more efficient pre-heating of the sheet prier to molding and includes the steps of blending reinforcing fibers with resin matrix forming fibers to form a web. This web is then heated to a temperature wherein the resin matrix forming fibers melt and envelope the reinforcing fibers, tacking them together at crossover points. The resultant web can then be directly heated very efficiently for molding. This web is highly porous allowing rapid heating at moderate pressure differentials during subsequent preheat steps. The microstruc-ture created when the resin matrix forming fibers are initially melted further enhances heating capability because the structure re-tains porosity during the subsequent heating step required for molding.  Because the resin matrix forming fibers initially were un-iformly blended, a highly uniform distribution of polymeric material within the reinforcing fiber matrix yields molded parts with very uniform properties.
