Title: Fluid torque-restraint system with optimized fluid expansion
Inventor: MCGUIRE DENNIS P
IPC: B64D27/00
Filed: 1992-04-22
Abstract: ABSTRACT                FLUID TORQUE-RESTRAINT SYSTEM WITH OPTIMIZED FLUID EXPANSION      A torque-restraint mounting system for connecting an aircraft engine to a structure including at least two hydraulic mountings and at least one other resilient mounting. At least two of the hydraulic mountings are fluidicly interconnected via a fluid filled conduit. This allows for the torque to be reacted between the aircraft engine and the structure by placing the fluid in compression. The relative torque-induced displacement occurring between the aircraft engine and the structure for any specific operating condition is counteracted by tuning the amount or volume of fluid within the torque-restraint system, or by tuning the coefficient of thermal expansion of the fluid. Thus, as the torque-restraint mounting system heats up, the aircraft engine will change rotational position such that its room temperature untorqued orientation can be maintained. This can have significant benefits in terms of increasing service life of the engine mounting system.

Title: Methods and apparatus for providing reciprocal impedance conversion
Inventor: CHAMBERS CHARLES W
IPC: H04B3/36
Filed: 1992-01-07
Abstract: METHODS AND APPARATUS FOR PROVIDING   RECIPROCAL IMPEDANCE CONVERSION   ABSTRACT OF THE DISCLOSURE          A reciprocal impedance conversion network is disclosed.  Such conversion network preferably is used in a reciprocal negative impedance repeater for the nonloaded cable facilities of a telephone system.  Two independent voltage sources for generating reciprocal negative impedance are connected between a first port and a second port.  The first port is operably connected to the first voltage source such that a series negative impedance appears at that port.  This port is specifically connected to the switching equipment of the telephone system.  The second port is operably connected to the second voltage source such that a shunt negative impedance appears at that port.  The second port is specifically connected to the nonloaded cable facilities of the telephone system.  The network further provides a frequency dependent gain circuit which is useful for equalizing the losses along the nonloaded cable facilities.  In addition, the network provides an unconditional stability test for the reciprocal negative impedance repeater which may be performed substantially without test equipment.  Also voltage feedback to the subscriber port proportional to subscriber current reduces the impedance as seen by subscriber line equipment and insures the proper operation of some impedance sensitive devices.

Title: Error based zone controller
Inventor: SHAH DIPAK J
IPC: F24F11/00
Filed: 1992-06-24
Abstract: The present invention describes an apparatus and method for balancing and controlling the temperature and a plurality of comfort zones within a house or commercial building. The invention contemplates a series of zone control devices which are selectively opened or closed to allow heating and/or cooling to individual zones. The temperature in each zone is sensed and compared to a preferred setpoint temperature to determine an error temperature for each zone. The respective error signals for each zone are used to determine the zone of greatest thermal error. The zone of greatest thermal error is used to turn the heating/cooling plant on and off. The remaining zones or zones of lesser thermal error have their zone control devices closed or opened, depending upon the error signal for their respective zones.  In this manner, all zones are synchronized to the cycle of the zone of greatest thermal error.

Title: Method for producing rolls or logs of web material and machine for implementing said method
Inventor: BIAGIOTTI GUGLIELMO
IPC: B65H19/22
Filed: 1992-07-10
Abstract: The method and machine is shown for the production of rolls or logs of web material. The web material is fed through a nip (5) formed between two winding rollers (1, 3) and wound up around a core to form a roll or log (R) within a winding space defined by said two winding rollers and by a third roller. At the end of the winding of a log, the third roller (7) is temporarily accelerated to locally increase the speed of the web and to put the web material in tension between the third roller and one of said winding rollers.  The tearing of the web material takes place because at that moment the incoming web is pinched between a new core and the one winding roller on which the material is driven out.

Patent CA-2076361-A1 (CA)
Inventor: BOGART FRANK J
IPC: H04Q3/545
Filed: 1992-08-19
Abstract: A call-processing arrangement (200) views a network numbering plan as a language in the mathematical/computer science sense and takes a lexicographic approach to call processing. Numbering plan syntax is defined by data in tree data structures (320, 330), and numbering plan grammar is defined by data in matrix data structures (400, 410). The data structures are used by numbering plan-independent functions to determine the meaning of call-associated digit strings and to specify the treatment (e.g., routing, features,) to be given to the call based on that meaning. A string-identification function (340) applies collected digits to the trees and matrices to find leafs (312) that define digit strings that make up the number. A string-action function (341) uses the definitions in the found leafs to form a call-route-specifying or call-feature-specifying index (254) for the call. A generalized route-selection function (343) uses a set of first call characteristics including the route-or-feature-specifying index to select from multi-dimensional matrices (1200, 1202) either afeature module (205) to be invoked or a routing-pattern number (1201), and in the latter case uses a set of second call characteristics including the routing-pattern number to select a route preference (1701) from routing pattern-preference tables (1300). A digit-sending function (344) uses the route preference to select an entry of digit-sending information (1701) from a sending table (1700) and uses the sending information to establish a call path and to outpulse digits. A digit modification function (343) and a table (1000) of digit modifications are also provided for purposes of number conversion, such as between different network numbering plans when more than one is defined.
