Patent GB-2065716-A (GB)
Title: Process for use when producing a part by powder metallurgy methods
IPC: B22F/
Filed: 1980-02-26
Abstract: When producing parts by powder metallurgy methods a metallic powder (3) is compressed to a basic porous blank or so called green preform, which by isostatic hot-pressing or forging in a tool is further compressed to the shape of the required part. In order to increase the wear resistance of the part the green preform is before hot-pressing or forging exposed to a gas mixture in a so called CVD-process (Chemical Vapour Deposition). During the exposure to the gas mixture a thin layer of hard material (6) is deposited on the surface and in the pores (4) of the green preform. The tool for hot-pressing or forging is protected from wear by depositing in the CVD-process an additional thin layer (7) on the top of the first layer of hard material (6). This additional layer is softer than the first layer and could preferably be of the same kind as the metallic powder.

Title: Thermal simulators for protecting electric motors
IPC: H02H6/00
Filed: 1981-08-04
Abstract: Overload protection for an electric motor is provided by two RC temperature-simulating networks each charged from a voltage representing the square of the motor current and each comprising a resistor 1301, 1700, a switch 16, 17 controlled by recurrent pulses, and a capacitor 24, 25. The voltage across each capacitor 24, 25 is compared (29, 30) with a respective reference voltage in order to detect overload. The time constant of the second network 1700, 17, 25 represents the conventional cooling of the motor, indicated by the manufacturer. The time constant of the first network corresponds to the cold starting time for a current equal to six times the nominal current. The second reference voltage corresponds to a overload of a few percent and the first reference voltage is greater than this. A cross-coupling network 27, 2701, 2702 prevents the voltage across the first capacitor 24 falling below that across the second (25). The pulses supplied to switch 17 are varied depending on whether the motor is being energised or not. <IMAGE>
