Abstract: Procedure for making Al₂O₃ spheroids, 600 micrometers in diameter or less, utilizes an AlOOH sol containing 0.25% weight percent MgO (in the form of Mg(NO₃)₂·6H₂O₃) and HNO;. The sol is dispersed into droplets in a particle forming fluid (e.g., 2-ethylhexanol) where gelling occurs. The gelled spheroids are collected, dried and pre-fired in air at temperatures less than 1,200°C for up to about 12 hours. The dried and prefired beads are fired in a 2-step process at temperatures of about 1,850-1,950°C in the following sequence: 
a first dry oxygen firing for about ten minutes, followed by a wet hydrogen firing for up to 350 minutes. Reasonably transparent microspheres having crystallites in the range of 5-100 micrometers are obtained with little intergranular porosity, and their density is estimated to be near theoretical.

Abstract: A viscous product dispenser is described which comprises a tubular container body (11) adapted to hold product, a take-up piston (13) at the lower end of the body (11) which decreases the internal volume of the container as product is dispensed from the container, and a bulk liquid pump dispenser (14) at the upper portion of the container body (11) having a product inlet extending into the container body (11) and a finger depressible, spring-biased piston/cylinder pumping mechanism. The pumping mechanism of the bulk liquid pump dispenser (14) has a product outlet conduit which is parallel and coaxial to the outlet axis of the product inlet and the center of the piston (13). The piston/cylinder pumping mechanism is of substantially less cross-sectional area than the internal diameter of the container body (11). 
     The take-up piston (13) can have a central depression to accommodate the lower portions of the housing of the pump dispenser (14) when the piston (13) reaches its uppermost location when the container is nearly fully evacuated of product. Transverse slot means cut downwardly in the upper surface of the piston (13) extend radially outwardly from the central depression to the sides of the piston (13) to provide a means to bleed or vent off unwanted air entrapped in product which lies in the central depression.

Abstract: Oxygen determination based on luminescence quenching of fluorescent dye is effected by using the frequency output of an offset-phase locked loop (15) to calculate the time constant for the exponential decay of fluorescence. An offset phase angle between a periodic stimulus signal used to excite the dye and a response signal based on fluorescence detection is predetermined to optimize signal-to-noise ration for a wide range of time constants. An offset-phase locked loop (15) is used to vary the frequency of a periodic stimulus signal until the predetermined phase relationship is established, and the frequency forms a measure of the decay rate. Where the stimulus and response signals are substantially sinusoidal, the offset phase angle is ideally about 49.3°, although substantially optimal performance is achieved using a more conveniently generated 45°. The 45° angle offset can also be used with a square-wave stimulus signal.

Abstract: The maneuvering area of a front and rear wheel steering vehicle is minimized by making the rear wheels (3) follow the trajectories of the front wheels (2). This can be accomplished by steering the rear wheels so that they may coincide, in a spatially fixed absolute coordinate system, with the steer angles of the front wheels when they were located at the same locations as the current positions of the rear wheels. Further proposed is a method for achieving the required rear wheel steering control which comprises the steps of detecting the yaw angle of the vehicle body and subtracting from the steer angles of the front wheels at the time point when the front wheels were located at the current positions of the rear wheels, the change in the yaw angle of the vehicle body from the said time point to the current time point. Thus, the vehicle is able to go through a most narrow and tortuous road for the given size of the vehicle without deviating from the prescribed course of the road, and the driver is required only to get the front part of the vehicle to pass through narrow points of the road without paying attention to the rear part of the vehicle.

Abstract: A fuel delivery system for purging air from the reservoir (22) of a diaphragm carburetor (18) on an internal combustion engine and for supplying priming fuel to the carburetor air intake (26). An manual pump (12) has an inlet coupled by a fuel line (16) through the carburetor reservoir to a fuel supply (20), and an outlet connected by the fuel line to a constant flow rate nozzle orifice (24) positioned at the carburetor air intake. A pressure switch (36) is connected in the fuel line between the pump and orifice and provides a signal, in the form of a switch closure, to priming control circuitry (46) whenever fuel, as distinguished from air, is pumped through the orifice to the carburetor air intake. The control circuitry receives battery power through the pressure switch contacts, and includes an integrator (50) for accumulating total time of fuel flow and thereby indirectly indicating the total quantity of priming fuel supplied through the constant-flow orifice. When the integrated time duration exceeds a selected threshold, an LED (58) is driven by an oscillator (56) to advise the operator to terminate the manual priming operation. Most preferably, the time-duration threshold is varied as a function of engine temperature.
