Abstract: Abstract of the Invention A single phase, high frequency, transistor or gate turn-off thyristor chopper ballast circuit especially suited for mercury vapor lamps preferably operates on unfiltered full wave rectified line voltage and electronically shapes the lamp current and therefore the line current to obtain a high power factor.  The ballast circuit is lightweight with low volume due to elimination of large low frequency energy storage, filtering, and transformer components.  The forced, high frequency ripple lamp current waveshape, achieved by comparison of the sensed current with an appropriate refer-ence signal, provides for good regulation, an initially high starting current to eliminate glow-to-arc mode, automatic sweeping of the chopping frequency to avoid acoustic resonance supply voltage for improved reignition characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE           Novel anatomical limb restraints are provided.  Such limb restraint or arm support structure includes a rigid elongate member for receiving the patient's arm in either of two positions during administra-tion of I.V.'s.  The device is generally concavo-convex in cross-section. The one side (top) of the support is convex at its forward end to receive the palm portion of the patient's hand and has a concave, tapered section rearward of the convex portion.  This configuration supports the patient's arm in a substantially horizontal palm-down position.  The opposite side (bottom) of the support is generally transversely concave to receive the patient's arm in a generally horizontal, palm-up position.  The opposite lower edges of the second side (bottom) are coplanar so that the arm support is stable when this side is resting on a flat surface.  A plura-lity of spaced-apart projections extend along opposite longitudinal edges of the support so that conventional medical tape can be wrapped about the support on the patient's arm at various selected locations to restrain and stabilize the arm support.  Recesses or notches at the forward end of the support receive the fingers of the patient in a curled position when the limb is in the volar position and the upper ends of the fingers and knuckles when the limb is in a supine position.  The support can also be used with an absorbent envelope or cover.  This limb restraint is there-fore suitable for use in intravenous treatment and provides for patient comfort and fulfills medical needs.

Abstract: METHOD OF AND APPARATUS FOR TUNING AN AFT-CONTROLLED      ELECTRONIC TUNER TO A DESIRED FREQUENCY                ABSTRACT OF THE DISCLOSURE     A method of and apparatus for tuning an electronic tuner of the type having a voltage-controlled tuning element to which a selected control voltage is applied, thereby tuning the electronic tuner to a corresponding frequency, the tuner additionally including an automatic fine tuning circuit which is operable even when a control voltage first is applied to the voltage-controlled tuning element.  When the control voltage first is applied, generally it experiences a gradual increase in magnitude until its predetermined control voltage level is attained.  The automatic fine tuning circuit may pull in a frequency corresponding to the instantaneous level of the control voltage during the gradual increase in magnitude thereof.          To avoid tuning the electronic tuner to this pulled-in frequency, the selected  control voltage is re-applied to the tuning element at a predetermined time subsequent to the initial application of such control voltage.     In a preferred embodiment, the electronic tuner is a programmable tuner provided with a storage device wherein repre-sentations, such as digital representations, of desired frequencies are stored.  The tuner is tuned to one of these frequencies by read-ing out a selected representation, converting the representation to a corresponding control voltage and then applying this voltage to the voltage-controlled tuning element.  The automatic fine tuning operation serves to modify the read-out representation, and thus the converted control voltage, to correspond to a pulled-in frequency The selected control voltage is re-applied to the tuning element by -i-reading out once again the selected representation from the storage device.                -ii-

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for the treatment of materials by the appli-cation thereto of ultrasonic longitudinal pressure oscillations, for example, for dispersing or emulsifying or dissolving or mixing or deagglomerating consists of an enclosure having an interior with two closely-spaced walls at least one of which is made to oscillate at ultrasonic frequencies, or otherwise impart such oscillations to the interior, for example, by ultrasonic tranducers mounted on the wall exterior.  The spacing between the walls is such that the longitudinal pressure oscillations produced at the oscillating wall are reflected by the other wall, preferably several times, before they are attenuated to a negligible value.  The wall is made as thin as possible and in its vibrating causes Doffler effects that avoid standing waves.  Pre-ferably the other wall also vibrates.  The distance  between the inner surfaces of the two walls is not more than about 1 inch (2.5cm).  The material to be treated preferably is fed to the enclosure interior under pressure from a storage container and is re-circulated until the operation is complete. The invention also comprises processes for the treatment of materials using such oscillations.  The transducers used may operate at different frequencies so that the material is subjected to different frequencies, and the frequency may increase in the direction of flow of the material through the apparatus.
