Title: Pre-swelling and etching of plastics for plating
Inventor: PATEL GORDHANBHAI N
IPC: C23C18/22
Filed: 1989-11-06
Abstract: ABSTRACT OF THE DISCLOSURE Formulations are provided for pre-swelling and etching of functionalized polymers, such as polycarbonate in one, two and three steps. The etched surface can then be plated with electroless nickel or copper with satisfactory adhesion of the plated metals. Swelling agents make polymer molecules on and near the surface ofthe polymer easily accessible to a degradation agent. A degradation agent degradates the polymer molecules. If required, a solubilizing agent increases the miscibility of the degradation agent and the swelling agent. A wetting agent increases the effectiveness of the etching agent.   In the one-step process, polymer parts are dipped in a solution containing at least one swelling agent and at least one degradation agent. In the two-step process, polymer parts are first treated with a solution of a swelling agent followed by etching with a solution of degradation agent. In the three-step process, polymer parts are first micro-roughened with a solution of a swelling agent, then etched with a solution of mineral acids followed by dipping in a caustic bath to make the surface wettable.

Patent CA-2020275-A1 (CA)
Inventor: HORST ROBERT W
IPC: G06F12/10
Filed: 1990-06-29
Abstract: A computer memory system is provided.  Received memory requests can be for addresses which are virtual or physical.  The type of address is determined, and a virtual/physical bit is set and stored.  At least row address bits are compared to one or more registers which contain either a virtual or a physical row address, corresponding to a row addressed by a row address latch.    When there is a hit with respect to one of these registers, column address bits are used to select the requested memory element, without the necessity for a virtual-to-physical translation.  When there is a miss on all registers, a physical address is obtained, either from the requested address when this is physical, or from a virtual-to-physical translation.  The physical address is used to load a new row address into a row address latch.  Some column address bits are changed only when there has been a miss.  A refresh cycle is described, which includes reading back into a row address latch the same row address which occupied the row address latch before the refresh cycle, thus preserving locality information or structure.

Title: Coiled tubing velocity string hangoff method and apparatus
IPC: E21B33/04
Filed: 1990-07-20
Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for hanging off a coiled tubing velocity string in an existing, active gas production well.          The method allows for the "hot" tapping into a charged coiled tubing run thereby eliminating the need for an end plug and blow out equipment on site.  A sealed cutter assembly is connected to the hangoff assembly, the charged coiled tube is cut, and back pressure leakage is avoided by the use of a hangoff head which seals in two directions.          The cutter assembly is removed and the coiled tubing velocity string is piped to a new sales line.

Patent CA-2034000-A1 (CA)
Title: Security paper for producing documents
Inventor: GATZ CARSTEN
IPC: B41M3/14
Filed: 1990-06-08
Abstract: A security paper can be used to produce documents which can be identified as genuine by means of a colour reaction system consisting of a colour-forming component and a colour-developing component and based on the principle of pressure-sensitive duplicating paper. The colour-forming component is applied to the paper, which contains the colour-developing component, by means of a marking device. A number of drawbacks are associated with known security systems for documents based on the principle of pressure-sensitive duplicating paper. The aim of the invention is to overcome these drawbacks. To this end, the security paper is placed in contact with a marking liquid which contains a colour-forming component.  The reaction between the colour-developing component present in the paper and the colour-forming component occurs in the paper itself instead of on the surface as in conventional papers. The marking penetrates the paper and may even strike through on the other side, where it forms a mirror image. This marking cannot be removed from the document without destroying the document itself. A  further major advantage of the invention is that a paper with an incorporated colour-developing component is a true security paper, i.e., comparable with conventional special papers (with fluorescent inlays, small engravings, watermarks, metal threads, etc.) which are note available to the general public. This appreciably enhances the security.
