Abstract: ABSTRACT OF THE DISCLOSURE          A tension measuring apparatus measures the tension in a tow band being advanced under tension.  The apparatus includes a sensing roll which is carried by a pair of torsion bars which carry strain gages.

Abstract: ABSTRACT OF THE DISCLOSURE      A low loss aluminum stranded transmission line is composed of a steel core member formed by a plurality of steel wires for providing the tension strength of the line and an aluminum portion formed by a plurality of aluminum element wires twisted around the steel core member in at least one layer.  The steel core member includes higher tension strength wires than the standard steel wires of a standard transmission line.  Thus, the diameter of the steel core member can be reduced to be smaller than that of the standard steel core, without decreasing the break weight.  In the aluminum portion, some, or all of the element wires have a fan-shaped cross section, so that the cross sectional space factor of the aluminum portion is actively increased to reduce the electric power loss during electrical transmission.  Also, at least one projection of fin-shape form on at least one element wire of the aluminum portion is located in the most outer layer of the aluminum portion.  This fin-shaped projection effectively prevents snow piling on the transmission line.

Abstract: A microphone and loudspeaker arrangement for use in a teleconference system, wherein a plurality of microphones are held in a fixed relationship to a loudspeaker. The microphones are independently gated ON in response to (1) speech picked up by the microphone, (2) a loudspeaker signal driving the loudspeaker and (3) an electrical signal related to the microphone signals of the other associated microphones. A noise adapting threshold circuit generates a voltage level representative of background noise which is compared with the microphone signal of a respective microphone for determining whether the microphone is receiving speech. A decisional circuitry monitors the microphone signal of the associated microphone with respect to a MAX bus which carries microphone signals representative of the level of microphone signals at the other microphones. The decisional circuitry generates a signal indicating that the associated microphone is the first loudest microphone signal.

Abstract: ABSTRACT OF THE DISCLOSURE IMPROVED FOAMING SYSTEM FOR RIGID URETHANE AND ISOCYANURATE FOAMS BASED ON POLYETHERS AND AROMATIC POLYESTER POLYOLS    Improved fluorocarbon blowing agents composed of blends of (a) CFC-11, triclorofluoromethane, with (b) CFC-123 or CFC-123a, dichlorotrifluoroethane, have been found which impart significant improvement in the solu-bility characteristics of rigid urethane foam systems that contain significant amounts of aromatic polyester polyols.  A substantial increase in the solubility of the CFC-11/CFC-123 or CFC-11/CFC-123a blends over CFC-11 alone in typical rigid urethane foam premix systems containing variable concentrations or aromatic polyester polyol is obtained.  Preparation of rigid urethane foams have shown that improved solublity CFC-11 blends with CFC-123 or CFC-123a permit an increase in the amount of aromatic polyester polyol than can be used in the formulation without any significant differences in the physical characteristics of foams compared to those produced from CFC-11 without inclusion of aromatic polyester polyols.     The solubility and compatibililty characteristics of the premixes which contain aromatic polyester polyols as substitutes for a portion of conventional polyols used in rigid urethane systems can be used effectively with the blend of CFC-11 and CFC-123 or CFC-123a blowing agent whereas use of CF-11 alone for such combinations of urethane polyol mixtures was heretofore substantially ineffective in regard to desireable solubility and compatibility characteristics.  The aromatic polyester polyols impart the following desirable characteristics to rigid urethane foams:  lower formulation costs, improved compressive strength properties, enhanced flame retardancy, and increased use-service temperature of low-density foams.

Abstract: BALANCE BEAM SCALE HAVING DIGITAL DISPLAY             Abstract of the Disclosure A beam scale includes a single weight mounted on a balance beam which is movable to selected posi-tions to establish ranges of weights to be measured.          The beam is supported by a flexible member to which a strain gage mechanism is secured to provide a vernier weight signal.  The electronic circuitry associated with the scale receives signals indicative of the adjustable weight position and indicative of the de-flection of the beam supporting member and totalizes these signals to produce and display a number indica-tive of the weight applied to the scale.  The scale permits the user operator to perform a simple calibra-tion procedure which guarantees the accuracy of sub sequent measurements by zeroing the scale and calibrat-ing it between the zero and fifty pound setting of the adjustable weight.  This provide  a balance beam scale which has greater accuracy than conventional mechanical balance beam scales and is far easier to use, particularly by an untrained person.

Abstract: MAILER FOR DELIVERY OF REPLACEMENT UNITS AND RETURN OF REPLACED UNITS                 ABSTRACT OF THE DISCLOSURE A mailer for the delivery of replacement units and the return of replaced units.  Preferably the units include electronic components such as PROM's mounted on printed circuit boards.  A replacement unit is held within the mailer by a restraint in a position such that an address for a customer to whom the replacement unit is to be delivered affixed to the replacement unit is visible through a window in the mailer.  Insertion of a replaced unit into the mailer causes the restraint to release the replacement unit and secure the replaced unit in such a position that no address is visible through the window.  Accordingly, the mailer would be returned to the vendor whose address is imprinted on the mailer with no need for further effort on the part of the customer.  In one embodiment of the disclosed invention, where the units are PROM modules mounted on printed circuit boards, when the replaced unit is partially inserted into the mailer the mailer may then be used as an extraction tool to remove the replaced unit from an edge connector, and when the replaced unit is fully inserted into the mailer the mailer maybe used as an insertion tool to insert the replacement unit into the edge connector.
