Abstract: NUMERICAL CONTROL RESOLVER POSITION MEASURING DEVICE          ABSTRACT    An absolute resolver position measuring device for a numerical control apparatus that controls a machine having a plurality of movable members.  A resolver is operatively connected to each movable member such that the rotor of each resolver rotates as the corresponding member moves. The resolver position measuring device includes a real time counter that provides a multi-digit data word that is cyclically redundant.  A first PROM is addressed by the real time counter and provides a sequence of digital data words which represent a sine waveform; and a second PROM is addressed by the real  time counter  and provides a sequence of digital data words which represent a cosine waveform.    A  first  digital  to  analog  converter  is responsive to the first PROM to provide a sine wave to the first  stator  winding  of  each  resolver,  and  a  second digital to analog converter is responsive to the second PROM to provide a cosine wave to the second stator winding of each resolver.  The waveform induced in each resolver rotor is input to a zero crossing detector and the outputs of  the  zero  crossing  detectors  are multiplexed  in  a sequential  order  onto  a  single  conductor.     This multiplexed signal is used to store the current count of the real time counter a plurality of times such that the stored  counts  represent  the  phase  angles  between  the corresponding resolver stator windings and rotors.

Abstract: IMPROVED PRESSURE-SENSING CAPACITOR AND         METHOD OF TRIMMING SAME                     ABSTRACT         A pressure-sensing capacitor and a method for trimming the capacitor is disclosed.  The capacitor in-cludes a pair of spaced flexible parallel quartz plates. A thin circular layer of conductive metal is formed on the opposing inner surfaces of the plates to define the electrodes of the capacitor.  A glass frit sealing compound, forming a concentric ring about the conductive layers, is disposed between the plates to seal the eva-cuated space between the plates.  The thickness of the ring is small enough so that the capacitance between the electrodes is higher by an unknown amount than the de-sired value of capacitance at every point in the range of variation of the value of pressure.  The capacitor is trimmed by first measuring the capacitance value at zero pressure and also at a maximum pressure.  The size and location of a path on one of the electrodes is computed from the measured capacitance values and the deflection characteristics of the plates.  A point on the inner surface of one of the flexible plates moves a maximum perpendicular distance towards the other plate under pressure.  That point defines a maximum deflection point along a deflection axis perpendicular to the inner surface at the maximum deflection point.  Radiant energy in the form of a laser beam is applied to the electrode to cut through the electrode along the computed path which is closed on itself to define a disc eccentrically spaced a calculated distance from the deflection axis so that the valve of capacitance at zero and the maximum pressure is substantially equal to the desired values.

Abstract: ABSTRACT OF THE INVENTION         Rolling mills for rolling seamless tubes from axially pierced blanks or billets using a restrained mandrel have suffered from a high dead time in operating cycle due to the necessity for returning  mandrel-restraining cross-piece or other member from its final position back to its initial position through the roll stands before a start could be made on positioning the next billet to be rolled This invention overcomes the problem by providing an elongate axially extending recess in the mandrel-restrain-ing crosspiece which allows the next billet to be positioned before the end of the preceding rolling operation, ready to be connected up immediately the mandrel-restraining cross-piece has returned to its initial working position, by enabling the crosspiece to pass over the billet which goes through the recess. Retractable positive acting mechanical the mandrel for a rolling cycle to commence.

Abstract: ABSTRACT OF THE DISCLOSURE           At each of terminal connected to a protected line section a current is sampled at an identical high sampling frequency, digitized, encoded and transmitted to an associate one of the terminals with the digitized data resistered in a first buffer memory.  Those processes are conducted under the control of respective clock pulses.  Also a receiver receives similar data from the associated terminal.  The received data are decoded and registered in a second buffer memory under the control of control signals from the receiver A shift register successively receives the data from the first buffer memory and shifts them through it under the control of a shifting pulse to compensate for a known transmission delay between the data in the two buffer memories.  The shift register and the second buffer memory write respective data into a processing unit in response to a writing pulse having a pulse width of a sampling pulse multiplied by an integer from the processing unit.  The processing unit compares two sets of data with each other to determine if a fault occurs within the protected section.

Abstract: ABSTRACT       A biochemical test system is disclosed for use in a biolo-gical fermentation sterilization indicator.  The carbohydrate component of the nutrient broth media is removed from the media. The carbohydrate component may be disposed in the cavity of an encapsulated sealed glass ampul which contains a non-carbohy-drated test solution.  Microorganism spores are also disposed in the cavity.  Upon completion of sterilization the ampul is broken; the contents mix.  Fermentation of viable spores yields growth and color change and is a positive test (unsatisfactory sterilization); no fermentation yields no growth, no color change and satisfactory sterilization.  The separation of carbo-hydrate prevents non-microorganism fermentation on the test reaction, and the appearance of a "false positive".
