Abstract: ENHANCED SOOTBLOWING SYSTEM               ABSTRACT OF THE DISCLOSURE         A method of identifying a parameter of a model for a rate of loss of boiler efficiency due to a soot-blowing operation, in a boiler or other convection heat transfer device having a plurality of heat traps, comprises measuring a time since a last sootblowing operation in the heat trap in question, measuring an overall boiler efficiency at the beginning of soot-blowing for the heat trap in question, measuring a change in efficiency due to the sootblowing operation and calculating the parameter using an equation.  Accord-ing to the equation, the ratio of efficiency change over overall boiler efficiency equals the time factor since the last sootblowing operation times the parameter minus a summation of factors for each of the other heat traps and their associated sootblowing operations.  A method is also disclosed for enhancing a sootblowing operation wherein, with a plurality of heat traps, sootblowing is performed in an upstream neat trap in preference to a downstream heat trap, when both heat traps are near a fouled condition which would require sootblowing.  This prevents premature fouling of a downstream heat trap which has recently been cleaned by soot blown off an upstream heat trap.

Abstract: Abstract of the Disclosure Intrapleural pressure of a newborn subject is measured by detecting relative movement between adjacently-proximate cranial bones.  The preferred device for measuring such bone movements is a surface inductive plethysmographic transducer secured on the subject's head across at least two adjacently-proximate cranial bones. The output signal generated by the transducer may be cali-brated to provide a measurement of actual intrapleural pressure by temporarily manually occluding the subject's nose or, if intubal, the endotracheal tube, measuring the airway pressure during such occlusion as the newborn makes an in-spiratory effort, and adjusting the transducer output sig-nal to equal the airway pressure measured with the nose occluded.

Abstract: ROTATABLE ELECTRICAL CONNECTOR FOR TELEPHONE CORD     ABSTRACT       This low friction rotatable electrical connector is for use with coiled telephone cords to prevent the cord from becoming twisted and knotted-up. This connector is generally of insulating material formed by a hollow inner cylindrical member telescoped within a hollow outer cylindrical member. A pair of ball bearing members support the outer member on the inner member for rotation about a central longitudinal axis. The inner member has a single longitudinal split for receiving a plurality of continuous conductive rings, and flexible insulated conductors extend through this split for connection to these. rings. A plurality of apertures are formed in the wall of the outer member in alignment with the conductive rings, and these apertures contain spring-biased balls in rolling contact with the rings. The exterior of the outer member supports a plurality of split conductive rings that are in alignment with the-continuous rings of the inner member as well as with certain of the spring-biased balls so as to maintain good electrical continuity between the continuous rings and the split rings. Flexible insulated conductors are joined to these split rings at one end and to a male electrical plug at the outermost end of the outer member. An insulated sleeve is fitted over the outer member, and it may include a hollow ball and socket joint that supports the male plug when the connector is fixedly mounted to the telephone base or hand set.

Abstract: ABSTRACT     A rotatable film wrapping apparatus for wrapping a load on a conveyor with an overwrap of stretched plastic film web, having a ring-mounted film web pre-stretch mechanism which stretches and dispenses film at a varying speed controlled independently of variations in film tension and speed between the pre-stretch mechanism and the load, and a supply speed control mechanism which varies the supply speed of web from the pre-stretch mechanism as the ring rotates.  The supply speed control mechanism is configured as a predetermined model of the load to minimize variation in film elongation and containment as successive load edges intercept film web during wrapping, thereby locking in these characteristics at predetermined levels for film web wrapped across the load side which ends at the edge.  Because the supply speed control mechanism drives the pre-stretch mechanism independently of the moving film web, tension reductions in the web caused by holes at web imperfections do not slow or stop the pre-stretch mechanism, so that holes move to the load without expansion and web destruction.  The supply speed control mechanism overcomes rotational inertia of the film roll and pre-stretch mechanism to accelerate and decelerate film supply without delay caused by inertia.

Abstract: ABSTRACT OF THE DISCLOSURE               METHOD FOR DESALTING CRUDE OIL      The salt content of a heavy crude oil is reduced by a method which comprises the steps of (a)  mixing 70 to 98% by volume of a heavy crude oil having a viscosity in the range 200 to 250,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant or an alkali, percentages being expressed as percentages by volume of the total mixture; mixing being effected under low shear conditions in the range 10 to 1,000 reciprocal seconds, in such manner that an HIPR emulsion is formed comprising distorted oil droplets having mean droplet diameters in the range 2 to 50 micron separated by aqueous films, (b)  breaking the resulting emulsion, and (c)  separating the resulting mixture into a layer of relatively salt-free oil and a layer of relatively salt-enhanced water. Heavy crude oils are desalted by the above method without requiring a hydrocarbon diluent.      The high surface area of the aqueous lamellae in the HIPR emulsion increases the probability of contacts occurring between them and the droplets of salt water originally present in the crude oil, and thus leads to greater desalting efficiency.

Abstract: APPARATUS WITH FORCE ISOLATION FOR MEASURING WEIGHT OF COLLECTED FLUID AND METHOD                    ABSTRACT OF THE DISCLOSURE      A urinary output monitor for determining the volume of fluid in a urinary collection bag during the collection process having a weighing apparatus for weighing the contents of a collection bag and means for substantially isolating the end of a drainage tube from applications of significant forces to the collection container.  The isolation mechanism is incorporated into the container assembly in the form of a conduit for interconnecting an inlet connector and an outlet connector which has sufficient flexibility to preclude it from conveying any significant force in a direction along its length which would adversely affect the weight measurement.  Since varying forces applied to the weighing apparatus by drainage tube connectors of different catheters are eliminated by the isolation mechanism, fluid entered after offset determination for zeroing the weighing apparatus to compensate for bag weight is includes in the total measurement.

Abstract: INVENTORS:  KURT MULLER, PETER GRUBER and ALFRED WUTHRICH        INVENTION:  INFRARED INTRUSION DETECTOR     ABSTRACT OF THE DISCLOSURE     An  infrared  intrusion  detector  having  a predetermined number of rows of radiation reception zones comprises a primary reflector and a secondary reflector for each row of radiation reception zones.  The primary reflectors and their associated secondary reflectors  form a  folded radiation path.  The folded radiation path allows for compact construction and simple manufacturing of the infrared intrusion detector.  One reflector of each radiation reception zone forms together with the infrared sensor a compact structural unit.          The other reflectors of each radiation reception zone are combined to form a further structural unit which is arranged in a predetermined spaced relationship to the  first compact structural unit.   In order to achieve uniform detection sensitivity in radiation reception zones having different angles of inclination to the horizontal plane, a larger focal length is chosen for radiation reception zones with smaller angles of inclination and longer range.  Likewise, to achieve uniform detection sensitivity even with oblique  infrared radiation  impingement,  the  surface  area of the primary reflectors increases within each horizontal row from the middle to the sides.

Abstract: Abstract of the Disclosure The invention concerns a method for arranging paper rolls coming, e.g. from a winder into a package suitable for delivery. The rolls are identified, end-labelled, and their width, weight and diameter are measured, whereupon a package is formed of a suitable number of rolls at a wrapping station. According to the invention, the rolls are transferred, each in its turn, to a positioning station, where they are identified and end-labelled one by one, whereupon the identification data and measurement data of each roll as well as of a preceding roll, if any, placed in the waiting position of the positioning station, are compared with the specification data of the package to be delivered. When said data of the rolls correspond to the specification data of the package, the rolls are transferred to the wrapping station, whereas, in the contrary case, the rolls are shifted to the waiting position of the positioning station. Thus, this acts as a sort of a buffer store for paper rolls. The most important items among the specification data are the delivery addresses of the rolls and the total width and weight of the rolls.

Abstract: "IMPROVED VIRTUAL MEMORY COMPUTER SYSTEM"               ABSTRACT OF THE DISCLOSURE        An improved virtual memory computer system. A main processing unit executes application programs. A dedicated second processing unit is provided for maintaining a memory map, which translates addresses in the main processing unit address space into physical memory addresses of a primary memory. A network interface allows pages or segments of data from a secondary memory connected to a communications network to be transferred into the primary memory in a manner transparent to the operation of the main processing unit.  Direct memory access means transfer the header portion of a network-transferred page of data into a separate auxiliary addressable memory for storage of network overhead information, while the useful data portions of the page are stored directly in locations in the primary addressable memory. A requested page of data is then placed directly in a desired location in primary memory without the need for moving or retransferring the data within the primary memory to strip off network header information after a DMA transfer.  The system is responsive to detect and correct a page fault condition prior to execution of the main processing unit instruction which generated the page fault, which obviates reexecution of instructions or correction of instruction execution results by the main processing unit.

Abstract: ABSTRACT     In a communications system wherein a transmitted message is preceded only by an address, an asynchronous circuit (100) detects the address and provides an initializing signal (at Q-NOT of 105) to a synchronous clock recovery circuit (114 and 116) so that the first bit of the recovered clock signal (at Q3 of 114) is synchronized to the first bit of the message.  During the transmission of the message the synchronous clock recovery circuit makes minor adjustments to the phase of the recovered clock to maintain synchronization between the recovered clock and the message.  At the termination of the message, the synchronous clock recovery circuit is inhibited (by Q of 106) until the asynchronous circuit detects another address.
