Patent CA-2277298-A1 (CA)
Inventor: ROLANDO JOHN J
IPC: C11D1/825
Filed: 1997-10-21
Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid. The detergent can be used in a variety of high temperature and low temperature automatic warewashing machines including large multizone conveyor machines, or relatively small institutional machines that have a single washing chamber.

Inventor: NEHME ANGELA FERRARIO
IPC: A61K31/7088
Filed: 1998-03-09
Abstract: The present invention describes a method for the selection and temporal expression of heterologous genes. The invention consists of methods to obtain selective and temporal expression of heterologous genes in target tissues. Promoters inducible by photodynamic therapy or heat are used to express genes of interest under conditions of heating or Photodynamic Therapy-(PDT-) induced oxidative stress. Selective and temporal expression of heterologous genes (such as cytokines, toxins, tumor suppressor genes, antisense molecules and anti-angiogenic factors) are of significant therapeutic benefit in the treatment of tumors, vascular proliferation and tissue hypertrophy. Gene therapy targeted by laser induced heating, other heating sources (such as microwave, ultrasound or radiofrequency induced currents), or PDT enhances treatment effectiveness by inducing expression of therapeutic genes in a controlled and localized manner.

Patent CA-2290965-A1 (CA)
Title: Photodetector circuit
Inventor: COLLINS STEPHEN
IPC: H04N5/355
Filed: 1998-06-15
Abstract: A photodetector circuit (100) fabricated in BiCMOS exhibits improved temperature stability. A bipolar phototransistor (200) generates a photocurrent (Ibi) in response to illumination. This photocurrent (Ibi) is passed through a diode connected load MOSFET (114) operating subthreshold which gives a logarithmic voltage output. This ensures a large dynamic range of the photon detection system. The phototransistor (200) has gain (.beta.) which amplifies an initial current response and ensures that current Ibi) through the load MOSFET (114) is significantly higher than MOSFET leakage current. This improves performance at high temperatures when the leakage current is large, whilst maintaining photodetector sensitivity to low illumination levels. The photodetector circuit (100) is particularly suitable for incorporation in a detector array (315) for use in a digital camera.

Patent CA-2311806-A1 (CA)
Title: Water sterilization system incorporating ultrasonic device
Inventor: DARWIN LAWRENCE C
IPC: C02F9/12
Filed: 1998-12-03
Abstract: A method and apparatus are disclosed for using ultrasonic energy in conjunction with an ultraviolet water sterilization system. An ultrasonic transducer assembly (36) is placed in or around one end of the sterilization chamber for producing the ultrasonic energy. Ultrasonic vibrations are then applied automatically on a regular and intermittent basis to clean the components within the sterilization chamber and disrupt the chemical and physical action which causes scaling due to dissolved minerals and organic materials in the water. The ultrasonic vibrations cause a preventive cleaning action by the streaming and stirring of the water. Actual cleaning action is also created by cavitation and sweeping actions. The sweeping action is accomplished by frequency modulation which, by creating varying hot and cold spots within the sterilization chamber, allows for a uniform cleaning of a quartz sleeve (26) encasing a UV lamp (16) within the sterilization chamber.      Ultrasonic vibrations also create a germicidal action.
