Abstract: ABSTRACT            A metallised composite structure and a method of preparing same.      The composite structure, which has a reflectivity of at least 85%, a heat-emission of about 8% of the Stefan-Boltzmann constant at 23°C, a mirror reflectivity (as defined) of at least 4 and dead fold properties the same as the substrate, is prepared by coating a smooth polymeric film (1) with a lacquer (2) which gives a releasable bond to the film and has a contact angle of zero degrees to the film, vapour depositing a metal layer (3) on the lacquer to produce a non-releasable bond, applying a laminating adhesive (6) to the metal layer (3) and bonding by means of the laminating adhesive (6) to a non-metallic substrate (7) and stripping the polymer film (1) from the lacquer layer (2).

Abstract: ADAPTIVE AIR/FUEL RATIO CONTROLLER   FOR INTERNAL COMBUSTION ENGINE            Abstract of the Disclosure:         An air/fuel ratio controller for an internal combustion engine including two memories each having numbers stored at locations addressed by engine operating points with the locations addressed by the engine operating points being updated during closed loop operation in accord with the value of a closed loop adjustment of the air/fuel ratio.  Each memory location in the first memory is updated during operation of the engine at the corresponding operating point in accord with an update time constant having a value so that the number stored tracks adjustment value producing the predetermined desired closed loop air/fuel ratio during varying values of engine operat-ing parameters.  Each memory location in the second memory is updated during operation of the engine at the corresponding operating point in accord with an update time constant having a value so that the number stored is the average of the values producing the predetermined closed loop air/fuel ratio during varying values of engine operating parameters.  The first memory is used during closed loop operation to preset the closed loop adjustment at least when the engine first operates at an operating point and the second Abstract of the Disclosure Continued memory is utilized during open loop operation to adjust the air/fuel ratio by an amount determined at least in part by the number stored in the second memory at locations addressed by the engine operating point.

Abstract: ABSTRACT   HYDROTHERMAL CRYSTAL GROWING PROCESS AND APPARATUS         Large single crystals of berlinite are grown onto seed crystals by maintaining the crystals at a fixed elevated temperature in a pressure vessel con-taining a nutrient of coarse berlinite crystalline powder, held at a fixed lower temperature, and concen-trated phosphoric acid.  Because berlinite shows retro-grade solubility, the nutrient goes into solution, and berlinite deposits on the higher-temperature growing crystal.  The vessel is rocked to promote motion of saturated solution to the crystal and depleted solution to the nutrient.  Large single crystals of alpha-gallium orthophosphate may be grown using the same apparatus and a similar process.  The resultant crystals may be cut into wafers useful in surface acoustic wave devices.

Abstract: ABSTRACT OF THE DISCLOSURE                The hot air ladle preheat station comprises an outer casing defining an opening for receiving a separately supported ladle. The opening is dimensioned so as to form a dilution air space about the ladle exterior.  A wall is spaced inward of the outer casing and defines a space therebetween having a lower section for accommodating the ladle in spaced apart relationship from the wall and an upper flue section.  Stack means are positioned for exiting flue gas from the upper flue section.  A burner means is associated with the wall in the lower section for directing a flame into the ladle and a recupera-tor means cooperates with the upper flue section.  Products of combus-tion are directed into the ladle and exit from the ladle in the space formed with the wall.  The products of combustion mix with and are cooled by the outside air entering through the dilution air space and the mixture thus formed passes through the recuperator in heat exchange relationship with combustion sustaining gas utilized in the burner means.

Abstract: ABSTRACT OF THE DISCLOSURE         A fuel feed system of a fuel priority type for an internal combustion engine.  The fuel feed system of the invention has a small auxiliary control unit with no calculation function in addition to a main control unit.

Therefore, even when the main control unit is out of order, the driver can drive his vehicle safely to a service station, etc. without stopping the engine.  When the main control unit is in a normal state, the main control unit performs engine air control (EAC) at a variable air fuel ratio in the whole range of operation.

Abstract: METHOD AND APPARATUS FOR REGULATING MICROWAVE OVEN POWER     Abstract of the Invention A method and apparatus for regulating a microwave oven to a predetermined output power level.  The anode current or a voltage corresponding to it is monitored to provide a signal indicative of the actual output power of the magnetron.          Time is divided into a sequence of equal time intervals, each interval corresponding to fixed number of ac line cycles.  In accordance with the signal, the number of ac cycles to be supplied to the power supply for each interval to regulate the output power towards the regulated level is determined.          The determined number of cycles are supplied by switching at the zero current crossings between the line and the power supply. The switching is executed so that the supplied ac cycles are distributed substantially uniformly over the particular time interval.
