Abstract: A PLASTIC NON-WAX SKI BASE AND METHODS FOR              ITS MANUFACTURE                    Abstract of the Disclosure A no-wax ski base of a composite material in which relatively harder particles are uniformly distributed in a plastic matrix.  The harder particles are angularly oriented with respect to the gliding surface of the ski base to provide a unidirectional friction coefficient that combines good gliding properties in the ski forward direction with good grip properties in the backward or "kick off" direction of the ski.          These friction properties are maintained throughout the entire life of the ski base irrespective of wear.         A method for the manufacture of such ski base by extruding the plastic composite material through a split nozzle while causing it to flow substantially asymmetrically through the split nozzle to obtain the angular orientation of the harder particles in the plastic matrix is described.

Abstract: A small-area focus solar concentrator comprising a linear echelon refractor and a linear echelon reflector. The increments of the refractor are crossed at approximately 90.degree. to the increments of the reflector.  The refractor and reflector cooperate to focus solar radiation incident on the front surface of the refractor to a small area focus in front of the refractor. The refractor-reflector structure permits relatively low cost, high power concentrators using refractorreflector matrices.  Also, the refractor-reflector structure can be used to focus normal or non-normal incident radiation outside the path of the radiation to reduce or eliminate blockage of the radiation by an absorber located at the focus.

Abstract: DIGITAL CARDIAC PACEMAKER          ABSTRACT       There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of cardiac stimulating pulses.  The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming sig-nals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signaling the acceptance of a programming signal, and means to reset the program acceptance circuit if extraneous signals are detected as programming signals. The program signal acceptance circuit performs several different checks on the detected programming signal including a parity check, an access code check and determining if the proper number of signals were transmitted with-in a given time.  The timing circuit of the pulse generator includes a crystal clock oscillator and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.

Abstract: ABSTRACT OF THE DISCLOSURE         A burner for pulverized coal such as in a rotary kiln includes three concentric cylindrical ducts.  The outer duct carries an air supply which is directed in a generally axial direction into the kiln.  The next innermost duct carries the pulverized coal-carrier gas mixture and is also generally directed in an axial direction.  The next innermost duct carries air which is directed in a divergent radial direction in the kiln and includes a rotational air component.  By controlling the quantities of air in the ducts which flank the coal duct, the resulting flame form can be controlled in the kiln without restoring to variations in the velocity or direction of the coal carrier gas stream.  By eliminating such variations in regard to the coal carrier gas stream, the abrasive action of the pulverized coal is kept to a minimum.
