Abstract: ABSTRACT            Title:  Improvements in Apparatus for Heat Sealing Thermoplastics Straps Apparatus and methods for heat sealing thermoplastics strap material comprising a portable tool adapted to receive two sections of strap material which are to be welded together and having a heating element, means for moving the heating element betwen the straps and a battery source for supplying heating current to the heating element.  A control circuit detects the battery voltage on load, and a drive circuit controls the movement of the heating element between the straps, to control the speed of the heating element in dependence on the detected voltage level, to compensate for decreasing battery voltage.  The battery source is mountd in or on the tool housing for portability.            The heating element is mounted on a carriage assembly mounted for reciprocal motion between the two straps and driven by an electric motor.            A shaft encoder associated with the carriage drive generates electrical pulses the frequency of which is proportional to the speed, and the number of which is proportional to the distance moved by  the carriage.            Switch means is employed for turning the heating current on and off and is actuated by the presence of the heater carriage assembly at particular positions along the carriage assembly path, determined by microswitches or counting the pulses from the encoder.

Abstract: ABSTRACT         In fluid level measurement apparatus a pressure vessel is tapped into a fluid container the fluid level in which is to be measured such that fluid level in the  vessel is representative of fluid level in the container.  A plurality of fluid detecting sensors are mounted in the vessel with non-equal spacing.  A problem with conventional apparatus is that levels in the vessel and container are not equal due to density difference between fluid in the vessel and container.  With the present invention, the error is overcome by compensation effected by non-equal sensor spacing, which may, for example, be made equivalent to equal level increments in the container.     27.549

Abstract: ABSTRACT OF THE DISCLOSURE                     ELECTRIC METER WITH ELECTRONIC ROLLING DEMAND REGISTER     An electronic demand register divides a demand interval into a contiguous set of N demand subintervals.  The demand in each demand subinterval is summed with the demands from the N-1 most recent contiguous demand subintervals to derive the interval demand.  The interval demand is compared with a prior stored maximum demand to decide whether to discard the present interval demand or to use it to replace the previously recorded maximum demand.  Demand is accumulated in terms of actual power usage by scaling power usage pulses according to the relationship in the particular meter on which the rolling demand register is used.  Thresholds are provided for producing warning signals to alert the consumer to an actual or impending demand condition which may adversely affect billing.

Abstract: STOP CHANGER TOOL FOR IN-SERVICE VALVE Abstract of the Disclosure A stop changer tool for removal of an in-service valve under pressure and comprised of a displaceable shaft assembly supporting at one end an axially compressible elastomeric plug adapted to be inserted through the valve into the upstream pipe.  The plug is mounted between a pair of restraining ends such that displacing the shaft assembly in a withdrawal direction draws the restraining ends toward each other to compress and diametrically enlarge the plug until a pressure sealing engagement is achieved with the pipe surface thereat. The restraining ends are formed of laterally displaceable contiguous elements having pre-determined face angles on opposing surfaces whereby they are relatively displaced laterally outward concomitantly with compression of the plug so as to substantially restrain the plug against axial extrusion.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a method for the qualitative and quantitative measurement, by means of microwave spectrometry, of the hydrogen isotopes, protium, deuterium and tritium, in a sample which contains hydrogen, water or a mixture thereof, and to an apparatus for imple-menting the method.  Because it is a prerequisite for the use of microwave spectrometry that the isotopes be present in the form of water, and it is advantageous to have impurities in the sample in the form of active or inactive foreign mole-cules that do not interfere, the present process converts the sample into the gas and/or vapor form.  The water vapor component of the sample is subjected to microwave spec-trometry and a first measured value compiled, the hydrogen component of the sample is converted to water and then subjected to microwave spectrometry and a second measured value is compiled, whereupon the two measured values are summed to provide the total isotope spectrum.  Only the non-condensable gases must be removed.  Processing of samples according to the method of the present invention permits the use of microwave spectrometry for the determination of the isotope spectrum in a hydrogen/water mixture.

Abstract: Abstract CNC TURNING MACHINE            A turning machine is characterized by a new and improved control and mechanism for positioning the turning tool on the head.  A CNC issues command signals for selectively positioning the tool on the head.          These  signals  are  developed  from  an  encoder which provides  the instantaneous position of the rotating part being turned and from a program in the CNC containing information about the part. A closed loop control system receives these command signals and converts same into a control current for a linear motor which is the prime mover controlling the positioning of the tool  on the head.   The linear motor operates a carriage on the head and the cutting tool mounts on the carriage opposite the connection of  the  linear motor to  the carriage.  The carriage is a hollow bar guided on the head by sets of  rollers which are cooperatively arranged  to provide yieldably forceful constraint of the bar.  The rolling action of the bar on the head provides a low friction, low inertia construction enabling rapid  response  to  CNC commands.   The head also contains  various sensors providing position and velocity feedback information for use by  the  closed  loop  control.   The  closed  loop  control  contains various circuit components organized and arranged to provide fast and  faithful  response  to  command  signals.   The  machine  has  the ability to accurately turn complex parts where position information is being rapidly update,  often in the tens of kilohertz frequency range.  Different parts can be turned by merely changing the CNC program.                           (FIGURE 1)

Abstract: 18.                         ABSTRACT           CONTROL APPARATUS FOR THE ELECTRONIC DETECTION IN ALTERNATING CURRENT TRANSMISSION LINES OF FAULT LOCATIONS CAUSING POWER LOSSES     The control apparatus has an antenna (10)  for the reception of electromagnetic radiation emitted from the alternating current transmission line.  The antenna (10) is connected to an amplifying device  (20)  the  signal  output  (22)  of  which  is  connected to an oscilloscope  (30)  in such a manner that the  output signals of the amplifying device (20) effect both vertical and horizontal deflection of the image spot on the image screen of the oscillo-scope  (30).    The  amplifying  device  (20)  is  constructed  for the amplification  of  a  broad  frequency  range  extending  from below the line frequency to about 1 GHz, wherein the amplification in  the  frequency  range  below  about  10  kHz  is  reduced.    The whole frequency spectrum of the output signals of the amplifier device (20) is fed to the oscilloscope (30).     In  the  course  of  monitoring  a  transmission  line  the  low frequency  signal  from  the  alternating  line  voltage  appears on the image screen of the oscilloscope (30)  as a smooth closed curve,  while  in contrast the high frequency signals originating from corona discharges at the fault locations of the transmission line  appear  as  disturbances  of the smooth closed curve.   The shape  of  the  disturbances,  their position on the  closed curve and  their  amplitudes  enable  the  type  and  condition  of  fault locations to be determined.   (Figure 1)
