Abstract: Abstract of the Disclosure In a clock pulse regenerator for generating a clock pulse sequence in response to an incoming digital data signal, there is described a regen-erator which produces the clock pulse sequence substantially free from phase jitter and phase deviation. From an input digital data, an oscillator pro-duces a sequence of first pulses at a frequency greater than that of the input signal.  In response to the first pulses, a first counter generates a sequence of regenerated clock pulses.  The input digital signal and the regenerated clock pulses are gated to form a gate pulse having a pulse width proportional to the phase difference between the two signals.  The gate pulse is selectively transmitted through a first gate and is then counted by a second counter which generates a pulse for every predetermined number of first pulses.  Similarly, a third counter generates a pulse for each pre-determined number of leading and trailing edges of counted from the incoming data signal. The first pulses and second counter outputs are selectively transmitted through a second gate in response to the output pulses of the third counter.  The outputs of the second gate are counted by a fourth counter which generates a further pulse for each predetermined number of inputs.  These pulses are used to reset all four counters in readiness for the next data signal.

Abstract: Abstract CONVECTOR HEATER    A convector heater is disclosed which has a front plate 1 with a surround 2 spaced around the periphery of the front plate 1 so as to define an air gap 3 between the front plate 1 and the surround 2.  A back plate 4 is connected at its periphery to the surround 2 and is spaced from the front plate 1 so as to define a convection air space 7 between the front plate 1 and the back plate 4.   The convection air space 7 is open to the surrounding atmosphere at the air gap 3.  A heat exchanger 8 is disposed at the bottom of the convection air space 7 for heating air to induce a convection air flow through the convection air space 7 from the bottom air gap 3b to the top air gap 3a.   A secondary air flow is induced into the air space 7 through the side gaps 3c, 3d by the main convection air flow.

Abstract: 47 ,994 ABSTRACT OF THE DISCLOSURE         This invention is an improved method for scanning for flaws on a surface utilizing dynamic correction.  Each individual scan signal is divided into a large number of increments, each increment representing a predetermined position in the scan.  A dynamic average is computed for each of the scan positions and flaws are detected by compar-ing the increment signals to the dynamic average signal for the same position.  This technique is especially useful to detect flaws on high quality tubing, such as used for nuclear reactor fuel rods or for nuclear reactor steam generator tubing.

Abstract: ABSTRACT      RECEIVER FOR DISPOSABLE SURGICAL SHARPS           A receiver for disposing of used surgical sharps particularly needles and scalpel blades, comprising an ad-hesive-coated, rectangular backing panel having a cover panel and two matrix panels attached along the sides there-of.  The matrix panels have cut-out windows of different sizes to accommodate the surgical sharps.  In use, one matrix panel is removed and discarded while the other is folded over and secured to the adhesive-coated side of the backing panel.  Used surgical sharps deposited in matrix panel windows are retained on the adhesive coating of the backing panel which forms the floor of the matrix window. When all matrix windows are used, or the surgical procedure is complete, the adhesive coated cover panel is folded over the matrix panel to seal the matrix windows and the sharps contained therein.  Preferably, the cover panel is trans-parent to allow the sharps to be visually identified and counted after the receiver is sealed.

Abstract: SINGLE AMPLIFIER VARIABLE GYRATOR            Abstract of the Disclosure A gyrator circuit is realized by using a single amplifier and six resistors.  In the configuration disclosed, the Z11 term of the characteristic impedance matrix is always automatically zero, and only the Z22 term must be forced to zero.  Thus this gyrator is implemented by selecting elements which satisfy a single equation, and the impedance values permissable thereby cover a wide range of values.  In addition, the impedance characteristics of this gyrator can be determined by selecting resistor ratios as opposed to actual resistor values.  Thus a substantial accuracy advantage is obtained in this fashion.
