Abstract: DESCRAMBLER SUBSCRIBER KEY PRODUCTION SYSTEM UTILIZING KEY SEEDS STORED IN DESCRAMBLER ABSTRACT OF THE DISCLOSURE A system for reproducing in a descrambler of a subscriber communication network a subscriber key signal that is unique to the descrambler and was used in encrypting a key signal that must be decrypted for use in descrambling a signal received by the descrambler. The scrambled signal is received by the descrambler together with the encrypted key signal and a key generation number containing an address for accessing a predetermined area in a memory contained in the descrambler. The system includes a circuit for providing a subscriber key generation signal that is unique to the descrambler; a subscriber key generator for reproducing the unique subscriber key signal by processing the subscriber key generation signal in accordance with a predetermined encryption algorithm upon the algorithm being keyed by a prescribed subscriber key seed signal that is unique to the descrambler; a secure memory storing a plurality of different subscriber key seed signals, and for providing the prescribed seed signal to key the algorithm when the area of the memory containing the prescribed seed signal is accessed by the address contained in the received key generation number; and a circuit for accessing the first memory with the address contained in the received key generation number. The subscriber key generation signal is formed by combining the received key generation number with a unique subscriber address signal that is stored in a second memory of the descrambler.

Abstract: RESISTIVE LINE CIRCUIT        Abstract Resistive battery feed circuits are normally not used because of lack of power supply noise rejection and attendant crosstalk coupling.  In this circuit the opamp and surrounding circuitry insure that power supply and ground noise do not couple into the tip and ring circuits as a metallic signal and improve crosstalk attenuation.  In addition, the opamp is used to split the 48 volts supply.

Abstract: ABSTRACT         A process for waterproofing surfaces, especially applicable to the interior surfaces of tunnels, canals and mines, comprising the steps of cutting strips of lining material; drilling holes spaced at regular intervals in the interior surface of the vault according to the various transversal sections of the tunnel to be waterproofed; fastening the strips of lining material to the vault by means of anchoring elements, broad-headed nails or fastening members, so that the strips of lining material are anchored to the vault of the tunnel; coupling each strip with the adjacent strips, in both longitudinal and transversal direction, to make a leak-tight weld between them.  The anchoring elements not covered in the coupling operation are then covered with accessory pieces of lining material and a cord or stringer of waterproof material is placed at the side edges of the lining sections, between the end strips and the lower part of said side edges.  The holes in the inner lining which enable the metal elements projec-ting from the vault to pass through the lining strips, as well as those joints between sheets or strips which, in addition to the welding between said sheets, which require watertightness of special quality are then sealed with an elastic sealer.

Abstract: The gas and water content of crude oil flowing through a pipeline is measured using a flow restriction in the pipeline, a radioactive source for providing separate radiation energies for each component to be measured, a detector for detecting the radiation transmitted by the various components to generate a first set of signals, pressure gauges upstream of and in the flow restriction for providing a second set of signals, and a signal processor for correlating the signals to provide mass flowrate values indicative of the relative proportions of the components of the mixture. The temperature of the mixture in the flow restriction can also be measured and fed to the signal processor for ensuring that accurate values of flowrate are obtained when temperatures vary.

Abstract: ABSTRACT OF THE INVENTION           A method of producing a gel of an organic liquid, using a metal phosphate ester in which all of the reagents are substantially free of water and pH-affecting substances. The gel is particularly useful in fracturing subterranean formations by entraining a solid particulate proppant therein and pumping the resultant mixture into the subterranean rock formation at sufficient pressure to fracture the formation.  The organic liquid is preferably a hydrocarbon such as diesel or crude oil, and the metal phosphate ester is preferably an aluminum phosphate diester. The metal phosphate diester may be prepared by the reaction of a triester with P2O5 to produce a polyphosphate, which is then reacted with an alcohol to produce a phosphate diester. The latter diester is then added to the organic liquid along with a non-aqueous source of aluminum, such as aluminum isopropoxide in diesel, to produce the metal phosphate diester.  The conditions in the foregoing two reaction steps are controlled to provide a gel with good viscosity versus temperature and time characteristics.

Abstract: INVENTION APPLICATION                 CROSS COUNTRY SKIING MACHINE                          SIMULATOR           ABSTRACT   This invention describes a cross country skiing exerciser consisting if a metal frame which contains four tracks on which four carriages slide: two for the trainee's feet and two for his ski poles, all said carriages being interconnected via a flexible steel cable running over a plurality of pulleys in such manner as to simulate cross country skiing.     SPECIFICATION   Medical and fitness authorities agree that the best cardiovascular exercise is cross country skiing.  Some of the reasons are: 1. Rapid rise in heart rate and oxygen consumption. 2. More muscles involved than in almost any other sport. 3. Stand up exercise--works some of the largest muscles in the body for greater oxygen consumption. 4. Fluid, natural movements, akin to long stride walking. 5. Less boring, people will exercise longer. 6. Non jarring, far easier on joints and ligaments than jogging or jumping in place. 7. Promotes flexibility of the joints because of the large number of joints being flexed.           The present invention relates to a machine which closely simulates the movements of a cross country skier.  The machine can be used indoors to train for cross country skiing in the off-season or to train for cardiovascular (aerobic) fitness and can be used by men and women of all ages.           Most fitness machines presently on the market exercise only one or two muscle groups.  For example, bicycle exercises work only on leg muscles.         Rowing machines use primarily the arms and upper thigh muscles (quadriceps). Good aerobic exercise such as jogging or jumping in place are very hard on the joints and can lead to serious injury.           Next to cross country skiing, the best cardiovascular training can be achieved in a cross country skiing simulator such as the one described here.

Abstract: 52,569 ABSTRACT OF THE DISCLOSURE A nutating orifice dispersion apparatus applies a material to a work surface by producing a ribbon of the material as the apparatus is moved along the work surface The apparatus is omnidirectional and it does not have to be oriented with respect to the travel direction. More importantly, the flow rate through the dispersion apparatus can be modulated at will without affecting the ribbon pattern width. This feature is key to the robotic applica-tion of sealant in that the speed of the arm is not con-stant throughout the dispensing cycle and the material flow rate needs to be varied correspondingly in order to main-tain ribbon uniformity.
