Patent CA-2256300-A1 (CA)
Title: De-oiling process using enzymes
Inventor: LATTA CHARLES J
IPC: C11D11/00
Filed: 1998-12-17
Abstract: Compositions and methods are provided for cleaning and de-oiling metal parts and then degrading the removed oils or other organic compounds in an environmentally-friendly manner. The compositions generally contain surfactants to remove the oils and enzymes to degrade the oils. Generally, both aliphatic and aromatic compounds normally present in standard oils, lubricants, cutting oils, and greases are removed from the metal parts (i.e., "solubilized") by surfactants (although the enzymes may also assist in this process) and then ultimately broken down into relatively short-chain fatty acids by enzymes, both processes being carried out in an aqueous medium. The surfactants include (a) one or more alkylphenol ethoxylates; (b) one or more alkaline metal salts of an alkane sulfonic acid; and (c) one or more alkanolamines in aqueous solution. Suitable enzymes include monomethanoxigenase, alcoholdehydrogenase, and aldehydehydrogenase. Preferably, the aqueous enzyme solution contains all three types of the just-listed enzymes in order to degrade a wider variety of organic compounds derived form petroleum and petroleum products.

Patent CA-2269714-A1 (CA)
Inventor: SCHMIDT REINHOLD
IPC: F16L55/07
Filed: 1997-10-02
Abstract: A piece of piping (1) includes an outer pipe (3) and an inner pipe (2). The outer pipe (3) consists of a stable material impermeable to liquids. The inner pipe (2) that carries waste gas is made of a sintered material, preferably plastic, metal or ceramic, and is permeable to the liquid (9) as a function of a pressure difference between the space (8) between the pipes and the inner space (20), but is essentially impermeable to liquid when the pressure is equal. The space (8) between the inner pipe (2) and the outer pipe (3) is filled with the liquid (9). If a pressure is exerted on the liquid (9) in the cavity (8), the liquid (9) permeates through the three-dimensional system of pores of the inner pipe's wall, controlled by the pressure, and wets the inside of the inner pipe's wall evenly. If the pressure is increased still further, the liquid (9) begins to drip into the inner pipe (2). The system of pipes comprises at least one piece of piping through which waste gas flows. It prevents deposits and caking on the inside walls of the pipes by wetting these with liquid (9). A drop removal facility (23) with a drop collection space (24) prevents the liquid (9) flowing backwards by dripping down.

Abstract: A system and method for time division multiplexing multiple lower bandwidth signals into a high bandwidth signals such as a high-definition television signal. The invention provides an integrated transmission, distribution and routing signal format in which low-bandwidth signals are embedded in the active video and vertical blanking areas of a high-bandwidth signal. Data from the source data streams , including timing data, is formatted in packets, each packet comprising a plurality of channels. The packets are inserted into the high-bandwidth signal along with a header word  providing a 'data valid bit' or 'status bit' for each of the channels, which identifies valid data words within the packet. The source data streams are accurately reconstituted by de-multiplexing according to header data specifying routing destination, stream ID, stream type, channel usage and stream clock reclock reference for clock recovery at  the receiving end.
