Title: Backup protection switch to prevent reverse power flow in a ups
Inventor: MODEL MICHAEL J
IPC: H02J9/06
Filed: 1988-09-20
Granted: 1992-06-30
Abstract: BACKUP PROTECTION SWITCH TO PREVENT REVERSE POWER FLOW IN A UPS     Abstract A UPS system includes a mechanical backup input line isolation switch to provide mechanical isolation between the primary energy source connected to the input line and the secondary energy source upon detection of a failure of an electronic isolation switch normally providing isolation between the input line and the secondary energy source. Detection of such a failure is accomplished by means of a dummy load which is connected in across the input line. Its impedance is sized to permit a small low level of current flow, above normal leakage current levels premitted by a functioning semiconductor electronic line switch, if energy is reverse coupled from the reserve energy source via a failed electronic line switch without draining significant power from the primary energy source when the UPS is normally operative and deriving power from the primary energy source. A power flow direction sensing circuit detects the direction of power flow at the input to which the primary energy source is connected to the UPS and a control circuit responsive to the power flow direction sensing circuit disconnects the input from the primary energy source if reverse power flow is detected by activating a mechanical switch to disconnect the inputfrom the primary energy source.

Abstract: METHOD OF CONTROLLING COMBUSTION   IN FLUIDIZED BED INCINERATOR          ABSTRACT OF THE DISCLOSURE       In a fluidized bed incinerator for burning matter to be incinerated charged into a furnace by causing fluidization of a fluidizing medium with the assistance of air fed from the lower portion of a fluidized bed, a combustion control method is arranged such that: the combustion rate of matter for incineration in the furnace is detected by a combustion rate detecting means, and, when the combustion rate exceeds a predetermined level the amount of air fed from the lower portion of the fluidized bed is reduced:L and, simultaneously, the amount of air blown into a space above the fluidized bed is increased so as to control and maintain the combustion rate of the matter to be burnt in the furnace at the predetermined level and to suppress fluctuations in the amount of combustion air, the amount of exhaust gas, the oxygen concentration in the exhaust gas and the amount of gas remaining unburnt or the like.       The combustion control method is also applicable to a fluidized bed incinerator constructed to include a plurality of air chambers formed at the lower portion of the fluidized bed, through which chambers the air is fed into the in-cinerator and the combustion rate of matter for incineration is controlled by regulating the amount of air fed from the air chamber disposed at the portion where the matter charged is dropped.

Abstract: ABSTRACT    In anodic oxidation, using a conversion voltage as high as 100 volts, the region of anodizable metal layer covered with a vapor-grown insulation layer is not anodized.  It is believed that because the vapor-grown insulation layer is dense and has high dielectric strength and small leakage current, the layer functions as a protective mask even when a conversion voltage as high as 100 volts is impressed.  A metal insulation structure as taught in this disclosure has vapor-grown insulation layers having apertures, depsoited on an anodizable metal layer, and these vapor-grown insulation layers act as protective masks against anodic oxidation, anodized layers formed by converting at least the surface areas of said metal layers can be limited to an area of metal layers locating in the apertures of the vapor-grown insulation layers.

Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith high tensile modulus and high sag resistance without increasing melt viscosity, and a method of making the same. The graft copolymer is a polyolefin having a relatively high weight-average molecular weight methacrylate polymer grafted thereto. The graft copolymer is formed by dissolving or swelling a non-polar polyolefin in an inert hydrocarbon solvent, heating to dissolve the polyolefin, and while stirring the mixture, adding a methacrylate monomer, together with an initiator to produce a constant, low concentration of radicals, to form a graft copolymer with a high molecular weight polymer chain covalently bonded or grafted to the polyolefin backbone. The graft copolymer can be separated from the solvent, isolated by volatilizing the solvent, for example in a devolatilizing extruder, and extruded into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix. The blend exhibits improved physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet, blown bottles and the like. The graft copolymer further improves compatibility in a wide range of polymer blends.

Abstract: 1,037,429. Variable-ratio gearing. MAYBACH-MOTORENBAU G.m.b.H. Aug. 21, 1963 [Aug. 23, 1962], No. 33157/63. Heading F2D. A hydromechanical variable-ratio gear corn prises hydrodynamic torque converters 14, 16 connected in parallel and preceding a constantmesh spur gearing providing two forward and two reverse ratios. The common turbine shaft of the torque converters, which forms the input shaft of the spur gearing, can be braked by a hydrodynamic brake 44 to facilitate changing the ratio of the spur gearing. The transmission is particularly intended for diesel railway locomotives, the engine driving a shaft 10 geared to a shaft 13 driving the impellers of the converters 14, 16, the turbines of which are fast on a shaft 20 carrying the rotor 47 of the hydrodynamic brake 44. For the lowest speed range converter 14 is filled and converter 16 empty and drive is transmitted from the turbine shaft 20 through gears 22, 23, an engaged clutch 34, 35, gears 28, 27, an engaged clutch 42, 38 and gears 29, 31, 33 to a final output shaft 32. A second speed range is obtained by emptying converter 14 and filling converter 16, the ratio of the spur gearing being unchanged. To obtain third speed range, converter 14 is filled and converter 16 emptied, and clutch 34, 35 is disengaged and a clutch 36, 37 engaged so that the drive is transmitted from the shaft 20 through the engaged clutches 36, 37 and 42, 38 and through gears 29, 31, 33 to the output shaft. During this shift the hydrodynamic brake 44 is filled to slow the shaft 20 to facilitate engagement of the clutch 36, 37. All the clutches may be of a baulked dog type described in Specification 683,503. The top speed range is obtained on emptying converter 14 and filling converter 16. In a modification the converter 16 may be replaced by a hydrodynamic coupling. For reverse speeds clutch 38, 42 is disengaged and a clutch 39, 43 is engaged to clutch a gear 30 to the gear 28, the gear 30 meshing the gear 31 so that various speed ranges can be obtained by selectively filling converters 14, 16 and selectively engaging clutches 34, 35 and 36, 37.
