Title: Cardiac pacemaker with automatic a-v programming for optimization of left heart a-v interval
Inventor: CHIRIFE RAUL
IPC: A61N1/365
Filed: 1991-07-09
Granted: 1997-06-03
Abstract: A dual-chamber AV sequential pacemaker with the capability of automatically adjusting right heart AV interval to optimize left heart AV interval by compensating for pacing-induced inter-atrial and inter-ventricular conduction delays.  Depending on the pacing and sensing action, as determined by the patient's native rate, the predetermined  threshold  rate  and  intrinsic  AV  interval,  the pacemaker selects the AV interval.   Right heart AV interval is adjusted to compensate for the heart's inter-atrial and inter-ventricular delays.   Threshold values are previously estimated, using mean values measured using non-invasive techniques.   The pacemaker has a dual phase operating mechanism consisting of an analysis phase followed by a pacing phase.   The P wave rate is sensed and compared to a predetermined base rate. If the sensed P wave rate is above the baseline, atrial depolarizations will be sensed  by  the  pacemaker  and  small  number  (default  =  4)  of consecutive native AV intervals will be averaged.  If this average is less than a predetermined threshold value,  the system will continue in the demand mode, sensing P and R waves.  If the average is greater than said value, then the ventricle is paced for n number of times the analysis phase (default = 100 cycles), each followed by a short AV delay (Default = 50 ms) that is intended to compensate for the delay introduced in the onset of left ventri-cular depolarization after pacing the right ventricular apex.  When P wave rate is below the predetermined rate, atrial pacing will occur.   During the  initial  analysis phase,  the pacemaker AV interval may be extended to a higher value, say 250 ms, to allow measurement of the native AV interval.  At least four AV intervals will be averaged to compensate for possible Wenckebach phenomenon.          If averaged AV is greater than, say 220 ms, sequential pacing with AV of 160 ms will take place for 100 cardiac cycles. If averaged native AV intervals are less than 220 ms,  atrial pacing with ventricular sensing will be continued with the AV interval set at 250 ms for the next 100 cycles.  At the end of either 100 cycle period, another 4-beat analyzing phase is started.  Both pacemaker phases (analysis and pacing) are programmable. The 4/100 cycle sequence allows rapid pacing mode corrections under situations such as intermittent block due to exercise or other causes.

Title: Use of liquid carbon dioxide as a blowing agent in the production of open-cell polyurethane foam
Inventor: DOYLE EARL N
IPC: C08J9/12
Filed: 1990-11-13
Granted: 1997-07-01
Abstract: A process for the production of an open cell polyurethane foam comprises the mixing of the following components at ambient temperatures in a mixing zone: a diisocyanate having a functionality of at least about 2.0, at least one hydrogen donor, at least one surfactant which is effective in forming an open cell polyurethane foam, at least one catalyst, and a blowing agent comprising a gas having a boiling point below approximately -100°F at atmospheric temperature and pressure which preferably comprises carbon dioxide. In addition, the mixture may also optionally contain water. The mixture is subjected to a pressure in said mixing zone which is sufficient to maintain the blowing agent in the liquid state at ambient temperatures. After mixing the mixture is ejected from the mixing zone to atmospheric pressure, thereby completely and instantaneously vaporizing the blowing agent to provide expansion of the mixture. The resultant foam is then cured at ambient temperatures.

Abstract: This patent publication discloses a method and assembly for placing an identification label to the end of a paper roll (1). Prior-art methods for placing the label have been hampered by the long duration of the work cycle caused by the picking movement of the label. According to the present invention the label is picked by means of a clamp element (7) from a slanted surface inclined at an angle of, e.g., 45° from horizontal and transferred to the end of the roll (1) via an activation phase of the adhering surface by way of a continuous horizontal transfer movement, thus achieving a short work cycle. The assembly designed to implement the method performs the transfer movements by means of an arm (6) travelling along a guide rail (5) and a clamp element (7) connected by a joint (8) to the end of the arm (6).

The shrouds (94), (102), (110), (122) are then adjusted so that a further hull increment (88) can be worked on. The trolley (36) and extension-retraction of the platform support arms are operated by electrohydraulic winch (60) and hydraulic cylinders (80), (84), respectively. The margins (112) of the shroud (94) may be fastened by magnets (114) to the hull (18). Air drawn through the enclosed volume from above at (120), is drawn out near the dry-dock deck (12) at (46) for processing to remove dust and appropriately treat VOCs, if present.

Title: Double piano hinge vehicle suspension
Inventor: DION FERNAND
IPC: B60G9/04
Filed: 1993-01-07
Granted: 1995-05-02
Abstract: A  suspension system for  compensating road-borne loads applied selectively  to one end  of a vehicle wheeled  axle.  The suspension  system  includes a  pair  of  elongated rigid  tubes, extending longitudinally  over opposite sides of  the wheel axle, and supported  thereover by corresponding upright  posts anchored to the  intermediate section  of the wheel  axle.  Each  post and associated tube  have a number of  lateral interdigitating hollow ears, wherein the tube and post are pivotally interconnected by a lengthwise  rubber shaft.  A  bottom frame beam  from the vehicle body extends laterally outwardly  of each corresponding tube, and includes a plurality of ears interdigitating with additional ears from the proximate tube for through  engagement by another rubber shaft,  for pivotally interconnecting the  beam to the  tube.  In normal condition, each beam ear rubber shaft is downwardly offset relative  to the post ear rubber shaft.  Thus, as the axle on one side  of the vehicle is  lifted following a  road-borne load, the vehicle  beam on  that side  will sink  as well as  move inwardly toward  the  intermediate   portion  of  the  axle,  due  to  the deformation of the rubber shafts, whereas the vehicle beam on the opposite side will raise  as well as move outwardly away from the intermediate axle portion.

Abstract: In a method implemented by a telecommunications switch, a call request is made for a called party having a predetermined directory number. A determination is made if preconnection services are to be provided for the called party, and if such services are to be provided, a service node to provide the services is identified. A further determination is made if the call request is from other than the selected service node. If the call request is not from the selected service node, the call request is routed to the service node for preconnection services. If a call request is from the selected service node, the call is routed to the called party. This permits a selected service node to originate a separate call to the called party so that services can be provided on behalf of the called party in response to a call request made by a calling party. This method allows preconnection services to be provided without the requirement of multiple directory numbers being assigned to the called party.
