Patent CA-2050130-A1 (CA)
Inventor: CARAM BRUCE E
IPC: H04L29/00
Filed: 1991-08-28
Abstract: A communications system that is arranged to transport so-called connection oriented messages via respective virtual circuit connections is enhanced so that it also transports so-called connectionless messages via a predefined virtual circuit connection that is common among those data modules which participate in the connectionless message service. In particular, each module which participates in the connectionless message service is assigned, in addition to a primary address that is used in conjunction with associated channels numbers to transport respective connection oriented messages, a common address and a channel number that is usedsolely for transporting connectionless messages. In this way, the communicationssystem processes connectionless messages as though they were connection orientedmessages.

Abstract: A process is disclosed for the isolation of an enantiomerically enriched alcohol from a first mixture of an enantiomerically enriched alcohol and an enantiomerically enriched ester. The process includes the steps of: (a) contacting the mixture with a rea-gent capable of reacting with the hydroxy function of the alcohol, without the loss of optical purity, so as to produce a second mixture containing a base-stable derivative of the enantiomerically enriched alcohol and the unreacted ester; (b) contacting the second mixture with a base capable of reacting with the ester so as to produce a third mixture containing a compound more vola-tile than the base-stable derivative of the alcohol; (c) removing the volatile compound from the third mixture; and (d) converting the base-stable derivative of the alcohol back to the enantiomerically enriched alcohol, without the loss of optical purity.

Title: Deinking agent for the reclamation of waste paper
Inventor: TAKAHASHI YOSHIO
IPC: C09D9/04
Filed: 1991-11-28
Abstract: ABSTRACT OF THE DISCLOSURE A deinking agent for  the  reclamation of waste paper which comprises one or more of specific compounds is disclosed.   Each of the specific compounds used in the  present  invention,  which  is  obtained  by,  for example, further esterifying an alkylene oxide adduct of a dibasic acid, is characterized by being excellent in abilities  to  wash  and  disperse  ink  and  foaming properties.    Further,  each  is  a  dibasic  acid-series compound  and  is  thus  superior  to  common  nonionic surfactants in its ability to aggregate ink.  Therefore, these  compounds  show  good  performance  as  a  deinking agent.   In addition, they are in the form of a liquid and  thus  can  be  easily  handled,  different  from,  for example, fatty acids.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides a releasable adhesive joint between two elements.  The two elements are fixed to each other by means of an adhesive bead or by means of two or more adhesi-ve beads. The adhesive joint comprises a heatable separating member closely fitting the adhesive bead or embedded in the ad-hesive bead, or closely fitting or embedded in one of the adhe-sive beads. The heatable separating member looses the adhesion to the closely fitting parts of the adhesive joint or is de-stroyed upon heating the heatable separating member to a tem-perature at which the adhesive bead is not yet damaged, thus releasing the parts of the adhesive bead closely fitting the heatable separating member. This releasable adhesive joint is especially useful in fixing vehicle glass panes to a vehicle body frame.

Filed: 1992-08-04
Abstract: A combination motor-pump and soil separator assembly includes a reversible motor which drives a wash pump and a drain pump.          When operated in a wash mode, the wash pump directs pressurized wash liquid to one or more wash arms.  In addition, a centrifugally sampled portion of the wash liquid containing a high concentration of entrained soil particles is directed to a guide chamber.  The guide chamber is in fluid communication with a soil container, which receives the wash liquid to be treated.  Soil-laden water received within the soil container is passed through fine filters disposed in a wall of the soil container, resulting in a cleansed wash liquid.  The cleansed wash liquid is then returned to the wash pump, where additional wash liquid is added, for recirculation within the dishwasher.  Upon completion of a wash cycle, the motor is operated in the opposite direction, providing a draining action within the soil collector.

Abstract: A process for generating a surface slice for use in understanding or comprehending the inter-nal structure of a multi-dimensional dta volume and specifically a three-dimensional seismic data volume. The surface slice is a local N-1 dimension-al representation of the internal structure of N di-mensional data, where N represents the original di-mension of the data volume. Information from the Nth-dimension is preserved in the N-1 dimensional surface slices. An arbitrary surface intersecting sur-faces through the date volume is selected. A var-iant, an identifiable attribute of data which forms the surfaces of finite extent throughout the data vo-lume, is also selected and isolated to identify the surface. Variants can include, but are not limited to, peaks, troughs, local peaks, local troughs, plus-to-minus zero crossings, and minus-to-plus zero crossings. Isolated variants from the arbitrary sur-face are combined onto the arbitrary surface with isolated variants surrounding the arbitrary surface to create the surface slice. Isolated variants identifi-ed by their position in the data volume generate a time surface slice. Both quantitative and qualitative information on the local strike, local dip direction and dip magnitude of the intersecting surface are present. Isolated variants identified in any other manner generate an amplitude surface slice presenting both quantitative and qualitative information on the local strike and dip magnitude of the intersecting surface.
