Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a flame-retardant thermoplastic polyester resin composition consisting essentially of:  (a) a thermo-plastic polyester; (b) from 0.001 to 5 parts by weight, based upon 100 parts by weight of the thermoplastic polyester, of a phosphoric compound having the formula:                                                 (I) (where Ar and Ar', which may be the same or different, each represent aryl or substituted aryl groups having 6 to 23 carbon atoms), (c) from 0.001 to 5 parts by weight, based upon 100 parts by weight of the thermoplastic polyester, of a hindered phenolic compound, (d) from 2 to 40 parts by weight, based upon 100 parts by weight of the thermoplastic polyester, of a bromine based flame retarding agent, and (e) from 1 to 25 parts by weight, based upon 100 parts by weight of the thermoplastic polyester, of a flame retarding auxiliary component which is at least one selected from metallic oxides and metallic hydroxides.  The resin composition has good heat resistance and long-term property in spite of the presence of the organic aromatic bromine flame retarding agent and the inorganic flame retarding auxiliary component that tend to adversely affect the heat stability of the thermoplastic polyester resin.  The resin composition is useful for producing molded articles.

Title: Optical smoke detector
Inventor: BEST JAMES A
IPC: G08B17/107
Filed: 1987-12-15
Granted: 1991-07-30
Abstract: OPTICAL SMOKE DETECTOR                 ABSTRACT OF THE DISCLOSURE        A focused beam of light from a light source is directed into a closed smoke chamber, having inlets for admitting smoke particles,  toward a reflector which reflects and refocuses the beam back into the light source, the direct beam and the reflected beam passing through a test zone within the chamber.  In the event that smoke particles enter the test zone, the direct and reflected beams strike and bounce off of those particles to produce scattered radiation that will be picked up and detected by a light responsive sensor to generate an alarm signal.  By closely controlling,  rather than baffling the light, optimum operation is obtained, efficiency is enhanced and false alarms are minimized.   Additionally, to prevent any stray light from bouncing off of undesired dirt and dust in the chamber and being received by the light sensor, resulting in a false alarm,  surfaces of the chamber are provided with parallel grooves for accumulating that dirt and dust, and the light sensor field of view is focused on an attenuating light trap.  Stray light impinging on the grooved surfaces becomes attenuated and absorbed so there will be no reflections, and light entering the light trap is reduced to a negligible level.

Title: Method and arrangement for protecting turbine generators against subsynchronous resonances occuring in power transmission systems
Inventor: EDRIS ABDEL-ATY O M
IPC: H02H7/06
Filed: 1988-03-28
Granted: 1991-05-14
Abstract: Abstract of the disclosure:            This invention relates to a method by means of which a turbine generator can  be  protected  against sub-synchronous frequencies occurring in an electric network which is connected to the turbine generator and which in-corporates capacitors.  The method is based on de-equal-izing the subsynchronous natural frequencies of the three phases, so as to weaken the coherence of the frequencies. This is achieved by incorporating in each of two of the phases a respective inductance L of mutually different size and by changing the capacitance equivalently with a series capacitance C such as to fulfill the condition 1/LC = .omega.?, where .omega.o is the network frequency.

Patent CA-1340139-C (CA)
Inventor: SPARKS CHARLES E
IPC: G01N33/92
Filed: 1988-10-04
Granted: 1998-11-24
Abstract: The invention relates to a process for preparing standards and controls for immunoassays employing monoclonal antibodies. Monoclonal antibodies are used to isolate a restricted portion of an antigen containing an epitope that determines the specifity of the monoclonal antibody-antigen reaction so as to distinguish it from the antigen as a whole following fragmentation of the complex antigen by procedures including proteolysis. Isolated epitopes are attached covalently or by physical adsorption to particles to immobilize and stabilize the epitope. The particles can be composed of iodipamide ethyl ester, polyvinyl chloride polystyrene and other inert substances and can be chemically activated to improve epitope binding and stability. Experimental details demonstrate the binding of lipoprotein epitopes to IDE, polyvinyl chloride and polystyrene and the subsequent reaction of monoclonal antibodies to these particle-stabilized epitopes.

Title: Electro-optic waveguide device
Inventor: WIGHT DAVID R
IPC: G02F1/29
Filed: 1988-11-03
Granted: 1992-11-03
Abstract: ABSTRACT   An electro-optic waveguide device comprises an assembly of waveguides connected to a common light input region and forming a common far field diffraction pattern. The device comprises an n+ GaAs substrate bearing a waveguide lower cladding layer of n+ Ga0.9Al0.1As, which is in turn surmounted by a waveguide core layer of n- GaAs. The layer has grooves defining the waveguides, each of which has a respective Schottky contact. Each contact is biased negative with respect to the substrate, which reverse biases the respective Schottky diode waveguide structure. The waveguide core layer has electro-optic properties, and its refractive index varies with electric field. The phase of light emerging from each waveguide is therefore independently variable by means of its applied bias voltage. The waveguides are arranged to provide output confined very largely to lowest order spatial modes, so that they produce a single far field diffraction pattern. Varying the set of bias voltages applied to the waveguides produces output phase variation which changes the position of the diffraction pattern principal maximum to produce beam steering.
