Abstract: ABSTRACT OF THE DISCLOSURE          A method and an apparatus for performing the method, in which the quantity of production of glass fibers can be increased, while avoiding energy increase and while maintaining the unique temperature distribution which occurs at the circumferential wall when the height of the circum-ferential wall is raised to increase the quantity of glass fiber production or when glass fibers are produced out of so-called hard glass, namely such a temperature distribution that the tempera-ture in the center region of the circum-ferential wall is the highest of all, the temperature in the upper region of the circumferential wall is lower than the center region, and the temperature in the lower region is lower than the upper region.  The invention utilizes a centrifugal force and blast flame flow.

Abstract: ABSTRACT OF THE DISCLOSURE  SERIAL PRINT WHEEL IMPACT PRINTER           Disclosed is an improved serial impact printer which both prints and serrates a document.  The printer includes a print wheel which is rotated to position a selected character in front of an anvil.  The print wheel includes a wheel-like circular member having print characters at the end of fingers winch extend from the top of the print wheel's perimeter.  An impact mechanism pressures the selected print character against the anvil, the document being positioned between the selected print character and impact mechanism.   The impact mechanism includes a controlled torque do motor which turns a threaded shaft which is engaged with a threaded hole in the end of a hammer.  Counterclockwise motion of the d. c. motor advances the hammer's head to pressure the back of the print character against the anvil, thereby printing and serrating the document with the selected character.  Thereafter, clockwise motion of the d. c. motor restores the impact mechanism to its original position.

Abstract: Abstract An apparatus and a method for growth of material on substrates.  A substrate at temperature T2 is placed with a surface in contact with solution in streamline flow through a narrow channel.  The solution enters the channel with a temperature, T1, which is above its saturation temperature, Ts.  T2 is below Ts, so material will deposit on the sub-strate surface.  The flow of solution is maintained high enough to avoid the onset of constitutional supercooling.

Abstract: ICE FISHING RIG          ABSTRACT OF THE DISCLOSURE           The invention consists of a standard extending upwardly from the  ice  surface and having an inverted U-shaped tube on the upper end.  A flag with a counter-weight is pivoted to the standard and an elastic cord extends through the U-shaped tube and is anchored by one end thereof to the standard.   The other end has a ring which engages a trigger which in turn rests against the underside of the counter-weight portion when in the load-ed position and a fishing line is secured to the trigger.          When a fish strikes, the fishing line pulls against the trigger and disengages it from the counter-weight so that the elastic cord can retract and set the hook.  At the same time the counter-weight causes the flag  to elevate thus signaling a strike.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention is an electrical control system for controlling an electrical load device, particularly an inductive load such as the ballast of a gas discharge lamp which generates a back EMF when power is removed therefrom.          The control system includes a first electronic switch for controlling the application of power to and withdrawal of power from the load and a second electronic switch which controls the first electronic switch.  The second switch is responsive to a command signal preferably occurring between 90° and 180° of the AC power half wave to turn on and thus switch off the first switch which in turn withdraws power from the load.  The circuit remains in this state until a predetermined circuit condition occurs at which point the potentials on the load and the AC power supply are at predetermined levels.  The equal potential turns the second switch off, whereupon power is reapplied to the load by the first electronic switch.  In an inductive load, the back EMF generated when the first switch withdraws power from the load serves as a feedback signal which is referenced against the AC power supply to determine an equal potential circuit condition.

Abstract: TITLE          Device For Enhancing Cooling ABSTRACT OF THE DISCLOSURE         A device for enhancing the cooling of a friction disc according to the preferred embodiment of the teachings of the present invention is shown for use with a rotational control apparatus shown in its preferred form as a brake.  Due to the rotation of the friction disc, a forward flow of air is created by air flowing into entry ports into an air cooling chamber formed in the friction disc and past the periphery of the friction disc to the atmosphere.  The present invention directs cooling air radially inward into the friction disc at least in one radial segment of the friction disc at a time in a direction counter to the forward flow of air to enhance the cooling of the friction disc especially at relatively low RPM.  Speci-fically, the device of the present invention includes in its most preferred form a wire guard housing including a plurality of circular wires which are arranged in a parallel spaced relation and secured to the periphery of the external housing in which the friction disc is mounted for rotation.  A squirrel cage type fan is mounted to the wire guard housing for drawing air from the atmosphere and directing it under pressure inwardly into the friction disc.  Therefore, when the rotational speed of the friction disc is low, the rate of the forward air flow may be insufficient to dissipate the thermal horsepower of the brake.  The device of the present invention has then been found to enhance cooling especially at these lower RPM in spite of    providing forced ventilation counter to the natural flow and to increase the overall thermal horsepower dissipation.

Abstract: ABSTRACT OF TIE DISCLOSURE:      A steel strip heating furnace has a movable wall which can be positioned closer or farther away from the transverse edges of  the steel  in order to adjust the heat radiation applied to the opposing edges of the steel.  The movable wall extends parallel to the longitudinal axis of a course along which the steel is transported  through  the  furnace.   The movable wall constitutes part of a ceiling of a furnace body and can be  shifted  vertically  toward  and  away  from the transverse  edges of  the  steel  so  as to  adjust  the high-temperature heat radiation transmission area about the opposing transverse edge and thus control the heat applied  to  the  corresponding  section of  the  steel Also,  it is especially advantageous to provide means for cooling the movable wall so as to adjust the heat radiation therefrom.   Therefore,  the heating furnace can control the heat applied to the transverse edges of the steel so that the entire surface of the steel can be heated uniformly.
