Patent CA-1106890-A (CA)
Inventor: KAMATH HUNDI P
IPC: H01C7/02

Abstract: ABSTRACT         The invention relates to electrical devices comprising an electrode and a conductive polymer composition, preferably a PTC com-position, in contact with the electrode.          The process of the invention comprises contacting the com-position and the electrode while the composition is at a temperature (Tp) above its melting point (Tm) and the electrode is at a tempera-ture (Te) above the melting point of the composition, Tp and Te being the same or different, for a time which is sufficient to reduce the contact resistance between the electrode and the composition but which is not sufficient substantially to reduce the resistivity of the composition, for example, 2 time less than 5 minutes.  Preferably both Tp and Te are at least 20°C, especially at least 55°C, above Tm. In a preferred process the composition is melt-extruded over one of more pre-heated electrodes.  It has been found that the process of the invention substantially reduces the tendency of the resistance of the device to increase when the device is subject to thermal cycling.          The invention is particularly useful in connection with self-regulating heaters, especially strip heaters comprising a pair of stranded wire electrodes embedded in an elongate core of a PTC material comprising carbon black dispersed in a crystalline polymer.

Abstract: U. S. Seria1 No. 754,200 ABSTRACT       In a system for measuring blood pressure and the like based on a sensed quantity representing the sum of pressure applied by a pressure cuff and a fluctuating component representative of the pulsatile pressure within the blood vessel method and apparatus for indicating blood pressure only if that pressure determined in a first preferred manner correlates substantially with a pressure determined in a secondary, different manner.  More specifically, the sensed quantity is analyzed in a manner preferred for determining diastolic pressure and a manner preferred for determining systolic pressure, and the diastolic and systolic values so determined are compared with diastolic and systolic pressures or pressure ranges established by analyzing the sensed quantity in a secondary manner or manners. Examples of preferred and secondary techniques for diastolic and systolic, pressure determination are discussed.

Title: Processing of film without using  leaders
Inventor: HOPE HENRY F
IPC: G03D13/00
Filed: 1977-12-29
Granted: 1982-05-25
Abstract: ABSTRACT OF THE DISCLOSURE        Strips of photographic film are processed through a film developing machine which transports the film by means of rollers.  Curling of the film around the rollers of the machine is avoided even though no separate leader is attached to the film.      This is accomplished by first inserting one end of the film strip into a device which has an open slot defined by a pair of platens which face each other.  At least one platen is heated and at least one platen has corrugations in its slot-defining surface.  Provisions are made for responding to insertion of the strip into the slot to close the platens upon the inserted strip, and maintaining these platens so closed for a length of time sufficient to impress the platen corruga-tions into the film.  The slot is then reopened, the strip is withdrawn, and inserted into the nip of the input rollers to the developing machine.      Specific embodiments of the corrugating device are also taught.

Abstract: ARRANGEMENT FOR PROGRAM INTERRUPTION             Abstract of the Disclosure In a microprogram controlled processor a master mask signal, generated selectively under microprogram control, synchronizes the handling of asynchronously generated interruption requests to desired sequence stages in the interpretation of program instructions.  A programmed interrupt request (PIRR) associated with the interruption priority level of the program currently in control of the processor is maintained effective for a limited period of time after the associated program assumes control.  This period is determined by the presence of a PIRR (-bit) which is interruptable by any higher priority level inter-rupt request.  If a PIRR bit representing an interrupted program is still on when servicing of a higher priority level interrupt request is concluding control is returned to the interrupted program.  In order to avoid possibly locking out programs which are not associated with asynchronously generated interrupt requests -- e.g., supervisor programs -- a pre-settable interval timer is provided for operating after a predetermined time interval to force the setting of a PIRR bit and thereby force control to be transferred eventually to such programs.
