Patent CA-2142201-A1 (CA)
Title: Enhanced serrated fin for finned tube
Inventor: RYAN JERRY E
IPC: F28F1/36
Filed: 1993-07-15
Abstract: The present invention is an enhanced type of fin (14) for making an enhanced serrated finned tube (10) for use in heat ex-change applications. The segments (24), which are formed on the fin (14) when the fin is serrated, are enhanced either prior to serration or after serration. The enhancement consists of impressing, cutting or otherwise providing indentations (74) into the seg-ments (24), thus broadening the segments, increasing their surface area, and increasing their heat transfer capability. In addition, the base portion, i.e. the unserrated proximal portion of the fin, may also be enhanced to increase its surface area.

Patent CA-2150527-A1 (CA)
Title: Minimum harmonic distortion operating circuit for at least one low-pressure discharge lamp
Inventor: STATNIC EUGEN
IPC: H05B41/295
Filed: 1995-05-30
Abstract: To substantially reduce harmonic distortion and improve the power factor of an operating circuit for a fluorescent lamp, a smoothing circuit (G) is interposed between the outputs from a power rectifier (GL) and an inverter (WR) supplying the fluorescent lamp (L) with high-frequency energy.  The smoothing circuit includes a two electrolytic capacitor (C1, C2) - three diode (D1, D2, D3) network, which is so connected, and the diodes so polarized that, during charging of the capacitors, a series circuit is established with one (D2) of the three diodes in series with the two capacitors.  For discharge of the capacitors to supply the inverter when the rectified voltage is lower than the capacitor voltage, the two capacitors (C1, C2), through the other two diodes (D1, D3), are connected in parallel to supply the inverter.  To substantially reduce harmonic distortion to less than about 30% and improve the power factor of the circuit to above 0.95, a parallel resistor-capacitor (RC) circuit is connected between two junctions (V1, V2) serially with the series connected diode (D2).  The resistor (R1), in combination with the capacitors, reduces, and time-delays, inrush current upon charging of the capacitors (C1, C2).  The capacitor (C3) connected in parallel to the resistor (R1) permits backflow of high-frequency current from the inverter to the electrolytic capacitors (C1, C2), thus preventing transfer back to the network supply.

Abstract: The present invention discloses a new ribosome-inactivating protein, bryodin 2, isolated from the plamt Bryonia dioica. This ribosome-inactivating protein (RIP) is a type I RIP having a single polypeptide chain and no cellular receptor domain. Like many type I RIPs, bryodin 2 has a molecular weight of about 27,000 daltons and pI of 9.5. Bryodin 2 differs from previously identified ribosome-inactivating protein in its amino acid composition, amino acid sequence, and toxicity in vitro and in vivo. Bryodin 2 is useful, as are other type I ribosome-inactivating proteins, as am abortifacient, immunomodulator, anti-tumor or anti-viral agent.

Patent CA-2181166-A1 (CA)
Title: Process for the treatment of metal-containing water and recovery of metals therefrom
Inventor: MISRA MANORANJAN
IPC: C02F1/58
Filed: 1995-01-12
Abstract: Metals contained in various wastewaters are selectively recovered as metal precipitates and/or as spinel ferrite and water suitable for discharge into the environment is obtained. High grade magnetic spinel ferrite is recovered from wastewaters having aluminum and arsenic, if present in the wastewater, removed from the wastewater. There are three process stages for the treatment of wastewater. In the first process stage, which is optional, at least a portion of at least one non-ferrous or non-ferric metal is precipitated from the wastewater by subjecting the wastewater to an oxidizing agent to increase the oxidation-reduction potential of the water, by adjusting the pH of the wastewater to a pH at which the metal precipitates from the water and by adding an organic or inorganic sulfur compound, capable of causing the metal to form a precipitate, to the water in a quantity sufficient to precipitate the metal. When aluminum is present in the wastewater, aluminum is recovered from the water by adding a reducing agent to lower the oxidation-reducing potential of the water and by adjusting the pH of the water to about 5. The aluminum which precipitates in the aqueous solution is removed from the water. In the third precipitation stage iron is recovered as spinel ferrite in an ambient temperature process by adding a reducing agent to the water, adding a soluble ferrous salt to the water, adjusting the pH to about 9-12 and oxidizing the water with an oxidizer, e.g. air, to form spinel ferrite. If aluminum and/or arsenic are present in the wastewater and are removed from the wastewater by the process, high grade magnetic spinel ferrite is recovered.
