    摘要: A cell culture medium is disclosed which contains secondary sources of glucose comprising glucose-containing oligosaccharides or polysaccharides and hydrolytic enzymes (glucosidases) to liberate free glucose. Starch, for example, can be added to a culture medium to provide the controlled release of glucose when a serum supplement such as fetal calf serum, which contains the hydrolytic enzymes amylase and maltase, is used. Amylase breaks the starch down into glucose and maltose, and maltase converts the remaining maltose to glucose. The rate of glucose release can be controlled by regulating the amount of glucosidase activity present in the medium.

    摘要: Electrical apparatus wherein a plurality of batteries, for example, are controllably interconnected to form a power unit which accepts electric energy in a charging mode and feeds a load in a discharging mode. Controllers act through switches to interconnect the batteries in a way that permits them to accept unrectified electric energy from an a-c primary source the voltage and frequency of which may be variable; the energy is accepted over a substantial portion of the power cycle and the rate of charging is controllable; the controllers also interconnect the batteries in a way that permits the power unit to deliver energy to a load at a specified voltage and frequency. The power unit output can, for instance, be 60 cycle a-c, single or three phase. Thus, for example, the primary source can be a windmill-powered or water-powered generator whose output is a sinusoidal voltage that varies with wind or water velocity both in voltage and frequency and the power unit (or more probably a plurality of power units) can be used to provide 60 cycle single phase voltage for domestic use. In general, the batteries are charged in series and a controlled charging rate is maintained by a novel scheme for interconnection in a programmed fashion. The power unit can accept electric energy and feed a load as alternate conditions of operation, or a plurality of power units can be used to give simultaneous charge and feed; and the power unit can be employed as a substitute for the generator or other primary source, that is, to perform the function of an uninterruptable power supply (UPS). As a further example, the concept of changing roles can be employed in electric vehicle drives wherein the power unit electrically powers an a-c electric machine which acts as a motor during acceleration of the vehicle and as a generator during deceleration; the power unit feeds the motor at a variable voltage and variable frequency and accepts electric energy from the generator, again at variable voltage and variable frequency.

    摘要: Apparatus is disclosed for obtaining torque and angular velocity of a load transmitting shaft of a prime mover to provide control functions that can be fed back to the operational controls of said prime mover thereby to monitor and control the operating characteristics thereof. The apparatus is described primarily in connection with the preferred embodiment thereof in which torque and rpm data from the drive shaft of an automobile are used to derive further data in the way of electric signals which in turn are fed back to control the automobile output and provide, among other things, pollution and/or efficiency control for the automobile. The torque values are obtained using a light modulation scheme whereby the modulated light provides electric signals from which the torque information is derived.

    摘要: The bridge of a lute type instrument, such as a guitar, is supported by a bridge plate under the top of the instrument. The bridge plate is mounted to a stiff, rigid bracing in a manner which allows the plate to rotate about an axis in the direction of the neck of the instrument while preventing it from rotating forward under the tension of the strings. The bracing does not touch the top of the sound chamber except permissibily near the edges of the top. The thickness of the bridge plate varies monotonically transverse to the string direction to achieve optimal sound energy transmission over the frequency range of the instrument.

    摘要: A device for handling surface elastic waves using a plurality of reflective elements, such as grooves, on the surface thereof the dimensional characteristics of which may be arranged to vary in a predetermined manner from element to element to provide a bandpass filtering action on a surface wave reflected therefrom. The device may be formed in various configurations using single or double reflections to provide single or multiple filtering action or phase coded filter action and the orientation of the reflective elements may be varied to vary the center frequency of the filter. A further embodiment uses a compensating strip of material positioned in the propagating path of a surface wave, the dimensional characteristics of such strip being arranged to vary so as to change the velocity of the wave and to achieve phase error compensation thereby. Further, a strip of energy absorbing material may also be used to control the amplitude response of the filter.

    摘要: In optical scanning apparatus useful, e.g., for high speed digital communication of photographic images, a light source is arranged to produce a beam incident on a rotatable reflector along a path forming an acute angle with the scanning surface defined by the sweep of the reflected beam, and the scanning axis about which the reflector rotates is tilted with respect to the surface of the reflector and toward the scanning surface from the side thereof on which the beam is incident on the reflector, the axis thereby forming an acute angle with the scanning surface, the arrangement producing a desired approximation of planarity of the scanning surface.
