Title: Transformer leak alarm
Inventor: BUTLER DAVID MCMAHAN
IPC: H01F27/12
Filed: 1997-07-22
Abstract: Insulating oil in electric power transmission devices such as a transformer is filtered for removal of accumulated water and carbon particles. The filter and circulation pump are usually located in a separate cabinet external to the transformer with circulation conduits connecting the filter, the pump and the transformer. To prevent or minimize environmental contamination by leaks or ruptures in the oil circulation conduits, oil flow within the pump suction conduit is monitored independently of oil pressure within the pump discharge conduit. A flow rate or discharge pressure below a predetermined minimum operates motor control relays to terminate the pump drive motor operation and transmit appropriate alarms.      Additionally, an accumulation of oil in the dry sump volume of a pump and filter housing also activates motor terminating relays and transmits an alarm. Simultaneous with disconnection of the pump drive source, the pump suction conduit is closed by a normally closed solenoid valve positioned in the line near the power transmission device.

Title: Single-piece piston with central bore for use in a pneumatically-activated pump
Inventor: GRUETT DONALD G
IPC: F16N27/00
Filed: 1997-08-29
Abstract: A single-piece piston for use in a pneumatically-activated pump to meter a predetermined amount of lubricant or other liquid. The piston has a grooved end that includes a head portion and a circumferentially-disposed angled channel for containing a sealing member such as an O-ring. An adjacent stem section includes a longitudinally-disposed channel that is in fluid-flow connection with the angled channel. The piston is disposed within a chamber of the body of the pump. Lateral movement of the piston within the body causes the sealing member to shift and block and unblock the end of the longitudinal channel and an aperture in the angled channel, which allows liquid from a liquid chamber to flow into a central bore in the piston and to a pump chamber adjacent to the head of the piston's grooved end. The piston operates in association with an assembly for regulating the amount of liquid metered by the lubricator, a valve assembly for evacuating the liquid from the pump chamber into and through an outlet fitting, and a mechanism for regulating the flow of air into the outlet fitting to atomize the liquid.

Patent CA-2215591-A1 (CA)
Title: Thermally-insulated compound profile for doors windows and facades
Inventor: HABICHT SIEGFRIED
IPC: E06B3/263
Filed: 1997-09-16
Abstract: Thermally insulated compound profile for doors, windows, or facades.   The compound profile consists of metal profiles (5, 6) and insulating strips that are preferably of plastic and are joined to the metal profiles on the longitudinal edges. O the extent that the insulating strip or the insulating strips are connected to the metal profile so as to resist shearing, in the event that the metal profiles are subjected to uneven heating, the compound profile will curve out toward the side that is exposed to the greatest amount of heat. This sort of flexing is to be prevented.   This has been achieved in that, shear resistance is low, moves towards zero, or a coulisse {13) is incorporated within the longitudinal connecting area between the structural elements (2, 11, 5) that are joined.   The thermally insulated compound profile is used to manufacture the frames for doors and windows.

Filed: 1997-03-24
Abstract: A functional fragment antigen of tetanus toxin characterized in that the antigen comprises a fragment which is substantially the same as at least one type of the fragments obtained by cleaving at least one of the peptide bonds formed between the amino acid residues in the partial amino acid sequence present between the two cysteine residues participating in the disulfide bridge present on the N-terminal side in the full-length amino acid sequence of a full-length tetanus toxin molecule, also cleaving the disulfide bridge itself, and further cleaving the non-covalent bonds between the amino acid residues that constitute the toxin molecule peptide, that it has a molecular weight of 90,000 to 110,000 as determined by SDS-polyacrylamide gel electrophoresis and an isoelectric point of 7.25~0.5 as determined by isoelectric electrophoresis, and that it has an immunogenicity substantially equal to that of a full-length tetanus toxin molecule. This antigen keeps an immunogenicity as a tetanus vaccine antigen and is remarkably reduced in side effects. The invention also provides a process for the mass production of the functional fragment antigen, a vaccine containing this antigen, and a mixed vaccine comprising the above vaccine and a different vaccine.
Patent CA-2217350-A1 (CA)
Title: Treatment of fly ash
Inventor: SANTEN SVEN
IPC: C22B5/16
Filed: 1996-02-13
Abstract: A method and a plant for treatment of fly ash are described, wherein heavy metals are separated and wherein there is formed a leaching resistant slag. The treatment takes place in a reactor (2) and the fly ash is introduced into an oxidizing gas stream which is heated to at least 2500 ~C in a plasma generator (1). The fly ash melts and forms liquid drops of slag. A carbonaceous or hydrocarbonaceous material is added to the gas stream. This burns and supplies extra energy to the process. The ratio of oxygen and carbon is regulated in such a manner that the ratio CO2/CO + CO2 is kept within the limits 0.4 - 0.9. Heavy metals in the fly ash such as zinc and lead are thereby reduced and pass into the gas phase. The gas is discharged from the reactor (2), cooled and washed and metal oxides are separated. The gas will also contain chlorine and sulphur which are separated in a gas scrubber. The slag is collected in the bottom of the reactor (3) and can be continuously tapped via a slag lock (9). The slag's content of CaO and SiO2 can be regulated by the admixture of a slag-forming material with a high content of SiO2. A slag is thereby obtained with excellent leaching resistance.

Title: Use of foam materials derived from high internal phase emulsions for insulation
Inventor: DESMARAIS THOMAS ALLEN
IPC: C08J9/28
Filed: 1996-06-03
Abstract: The invention relates to the use of polymeric foam materials for insulation.  These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known in the art as high internal phase emulsions, or "HIPEs". The HIPE-derived foam materials used in the present invention comprise a generally hydrophobic, flexible, semi-flexible, or rigid nonionic polymeric foam structure of interconnected open-cells. These foam structures have: A) a specific surface area per foam volume of at least about 0.01 m2/cc; B) a density of less than about 0.05 g/cc; and C) a glass transition temperature (Tg) of between about -20~ and 90 ~C. The foams can be used as thermal, acoustic, and/or mechanical insulation materials. In a preferred embodiment, the foams used can be prepared, packaged, and shipped in a compressed, high density state and will "spring back" upon activation (e.g. heat) to the original density of the foam.

Title: Apparatus and method for template-based scheduling processes using regularity measure lower bounds
Inventor: RAMAKRISHNAN KAJAMALAI GOPALAS
IPC: H04L12/56
Filed: 1998-01-27
Abstract: An advantageous scheduling template slot ordering for use in establishing a scheduling order of events such as transmitting communication signals in a communication network is determined by assigning at least two initial slot positions to a particular signal class and then determining a regularity measurebased on a lower bound for the regularity measure of such assignments and the remaining unassigned slot positions. This lower bound for the regularity measure of the unassigned slots is advantageously based on a hypothetical assignment of fractions of the slot positions to different signal classes instead of limiting the assignment of a slot to a single signal class. This fractional slotassignment produces a regularity measure that is better than or equal to a corresponding regularity measure based on assigning a whole slot to a particularsignal class. The lower bound of the regularity measure is then compared with a threshold regularity measure, such as from a known reference scheduling template. If the threshold regularity measure is lower than the determined lower bound, then it is known that the reference template would provide a more desirable regularity of events than any template having the assigned slot positions to that particular signal class. As a consequence, other slot assignments can be compared to the reference template to rapidly identify scheduling templates with enhanced regularity characteristics.
