Title: Pacemaker with stepped increase or decrease to  altered rate
Inventor: RUETER JOHN C
IPC: A61N1/37
Filed: 1984-06-14
Granted: 1988-06-21
Abstract: ABSTRACT OF THE DISCLOSURE        A pacing system analyzer is disclosed which allows the user to measure pacing thresholds in terms of output current in milliamps, in a manner that many users are accustomed to, even through the output circuitry is actually adjusted on a voltage basis.  The output voltage is adjusted under the controls incre-ment and decrement keys on the keyboard of the analyzer.  The same increment and decrement keys may alternately be employed to control the pulse interval or stimulation rate once for every output cycle at the rate of pacing changes rapidly if the pacing rate is fast and changes slowly if the pacing rate is low.  This allows the device to arrive at an appropriate rate in a minimum rate of time and is especially useful when the user is employing rapid stimula-tion and the delivery of bursts of pulses to attempt to break up a tachycardia.  The pacing system analyzer includes further pro-visions for safely charging the output capacitor to power up even through the implantable pacing generator is connected to the anal-yzer.  In this event the voltage is ramped towards the voltage the capacitor will eventually charge to in a manner which limits the maximum current that is going through each chamber of the heart to a safe amount.  In addition, the pacing system analyzer has the capability of determining the pacing mode that an implantable pacing generator is operated in when it is connected to the anal-yzer and then of measuring and power and printing all of the appro-priate parameters associated with that particular mode.

Abstract: ABSTRACT           A process for constructing a hinge for thermoplastic material which is particularly suitable for loose-leaf binder covers is constructed by inserting a die into the thermoplastic material, the die having an embossed pattern consisting of alternating teeth and depressions along the face which contacts the thermoplastic material such that the die is embedded in the material to a depth less than the height of the teeth, such that the bottom of the depressions between the teeth do not contact the thermoplastic material.  Sufficient heat is then generated at the die to melt the thermoplastic material in conformity with the embossed pattern of the die.  The thermoplastic material is then cooled until it hardens.  The resulting surface of the thermoplastic is a hinge containing indentations corresponding to the pattern of the embossed die, which permit the thermoplastic to be folded at the hinge area.

Abstract: ABSTRACT OF THE DISCLOSURE          The performance and condition of a tool 101, workpiece 519 or machine tool is sensed during machining operations by securing a single or plural 2603 strain gages to the tool holder.  To increase the sensitivity of the strain gages on stationary tool holders, the tool holders are contoured to provide locations 1702, 2602 of higher strain in which the strain gages are attached.  A single or plural strain gages (1702, 2602) are positioned to sense the combined effect of different strains such as axial thrust and torque and are electrically connected to provide a single Wheatstone bridge output "signature" which may be monitored to detect a defective operation.  In rotating tools, the single "signature" output greatly reduces the coupling equipment such as rotary transformers and also reduces the monitoring equipment.  A unique arrangment of a single strain gage or alternatively a plurality of gages enables monitoring of both torque and thrust simultaneously.  The output from the plurality of strain gages can be made additive to increase sensitivity and yet requires only a single bridge circuit.  The design is flexible in that the gages may be arranged for optimization of the single bridge output for either torque or thrust.

Abstract: Abstract A fishing lure comprises a flexible lure body having a preformed cavity therein.  The cavity has a leading end and a trailing end, and the lure body has an insert opening through the exterior thereof into the cavity.  An insert mounted in the cavity is selectively removable therefrom through the insert opening.  The insert has a leading end disposed adjacent the leading end of the cavity and a trailing end disposed adjacent the trailing end of the cavity.  The insert is either preformed with  or forcibly malleable to assume a configuration differing from that assumed by the cavity in a relaxed condition without said insert therein.   The insertion of the insert into the cavity will  thus cause deflection of the  lure body  in a direction from the leading end to the trailing end and alter the external configuration of the lure body.

Abstract: ABSTRACT OF DISCLOSURE     An improved valve mechanism for an apparatus for conveying solid particulate material.  The conveying apparatus includes a casing having a bore therethrough with an inlet for material to be  conveyed  and  an  outlet.   A  screw  impeller  is rotatably mounted in the casing by front and rear bearings with the rear bearings  being  positioned  near  the  inlet.   Material  is discharged  from  the  casing  through  a  coaxial  outlet  into  a discharge chamber.  Gaseous fluid under pressure is supplied to the  discharge  chamber  for  entraining  and  conveying  the particulate material through a pneumatic conveying line which is flow connected to the outlet of the discharge chamber.  An improved valve mechanism is disclosed which closes the outlet of  the  casing.   The valve  is  biased closed by a weight and opened by material being advanced by the screw impeller.  The valve includes a valve plate which surrounds the shaft of the screw impeller to provide a seal at the casing and to at least partially  seal  around  the  shaft  to  substantially  prevent gaseous  fluid  from entering the casing in the event material flow  through  the  casing  is  stopped.   The  valve  mechanism includes a valve element having an opening therethrough which is large enough to permit the impeller shaft to extend through the valve.  The valve element is shaped so that it includes a first  portion which defines  half  or  the opening through the valve element and the second portion which defines the other half  of  the  opening.   The  first portion  is  longitudinally spaced from the second portion so that when the valve pivots from a closed position to an open position,  the edges of the opening adjacent the shaft will pivot away from the shaft at least during the initial stages opening valve.
