Abstract: WALSH FUNCTION MIXER AND TONE DETECTOR                    ABSTRACT OF THE DISCLOSURE            A mixer stage having particular application to digital detectors.  The mixer stage includes first and second sets of transmission gates and a Walsh function generator.  The first set of transmission gates is driven by sine function coefficient signals from the Walsh function generator so as to open and close individual gates of the set so as to effectively multiply an input signal by the sine of a tone reference frequency to be tone detected.  Similarly, the second set of transmission gates driven by cosine coefficient signals from the Walsh function generator so as to open and close individual gates of the second set to effectively multiply the input signal by the cosine of the reference frequency to be tone detected.  To form a complete digital tone detector, the sine and cosine multiplied outputs of the mixer stage are each filtered and squared and are then summed and further filtered to provide a "detect" signal when the input signal includes the reference frequency.

Abstract: FRICTION REDUCERS FOR LUBRICANTS AND FUELS            ABSTRACT         N-alkoxyalkyl amides may be formed by the reaction of primary alkoxyalkylamines with carboxylic acids such as formic acid, or alternatively by ammonolysis of the appropriate formate ester.  The resultant amides exhibit friction reducing properties when incorporated in additive amounts in lubricants and fuels.  Extremely low concentrations of such additives, i.e. N-alkoxyalkyl formamides in lubricating oils result in vastly improved, i.e. lowered coefficients of friction.  By virture of the friction reducing characteristics and lubricity properties, the additive compositions of the present invention exhibit reduced wear on rubbing surfaces.

Abstract: ABSTRACT      The presterilization of packaging machines for the manufacture of aseptic packing containers can be carried out with the help of sterile air and liquid sterilizing agent, which are blended so that a gas saturated with sterilizing agent of a suitable temperature and dew point is obtained.  In order to achieve a rapid and effect-ive volatilization of the liquid a circulating movement is imparted to the hot sterile air at the same time as the sterile liquid is introduced into the centre of the circulating movement.  An apparatus for the realization of this comprises a chamber     with a helical guide rail     and a spray nozzle     for the sterilizing liquid.

Abstract: ABSTRACT    A method of terminating the fiber core of a fiber optic cable relative to the mating end of a fiber optic connector.  The connector includes a through hole for receiving the fiber optic cable with a length of the core, stripped of its outer coating, protruding from the through hole at the mating end of the connector.  The method includes the steps of clamping the fiber optic cable within the connector against lengthwise movement of the cable, cleaving the length of the core flush with the mating end of the connector, and applying a separa-tion force lengthwise of the core during the cleaving thereof.  A flat, smooth end surface results and thereby eliminates subsequent polishing or other preparation of the core end.

Abstract: ABSTRACT     A compact, unfired, staggered tube, once-through steam generator or boiler of simple construction intended primarily for combined cycle power plants in which the thermal energy utilized to generate steam is obtained from the exhaust gases of a gas turbine engine.          The boiler provides steam at two different pressure levels, which maximizes recovery of thermal energy; and all wettable components in the steam/water loop are fabri-cated of corrosion resistant materials.  This eliminates the need for controlling the pH of the feedwater and the need for chemically controlling its dissolved oxygen con-tent, thereby reducing maintenance and operating costs and making automatic, unattended, remotely controlled operation of the boiler practical as well as eliminating the need for blowing down the boiler and minimizing re-quirements for make-up water.  The boiler can be operated dry to remove gas side fouling; and feedwater flow rates can be directly controlled.  Orifice-generated pressure drops at the inlets of the boiler tubes which are rela-tively large compared to the pressure drop in the rest of each tube eliminate the flow instability that is charac-teristic of once-through boilers.

Abstract: FROZEN ISLAND AND METHOD OF MAKING THE SAME         Abstract of the Disclosure An island adapted to be put into place in arctic regions in a body of water having a soil layer below water level and above a permafrost line.  In one form of the island, an island body is placed on the soil layer, the island body comprising a number of vertically stacked layers of freezable material, the bottom of each layer having a freeze panel adjacent thereto in heat exchange relationship therewith.  A coolant flowing through the panels causes the soil layer and the freezable layers to freeze, the coolant source being on the island body at any suitable location.  The island body surrounds a recess which also contains several layers of freezable material separated by freeze panels adapted to receive a coolant for flow in heat exchange relationship to the freezable layers.  By freezing the freezable layers, the island body is provided with a monolithio construction and the island body is bonded to the soil layer.  In another form of the island, a caisson is floated to a location above a dredged-out area in the soil layer and then lowered into place.  The caisson is adjacent to the soil layer and separated by a space which is filled with fresh water which can be frozen when a coolant flows through an adjacent freeze panel in heat exchange relationship to the fresh water.  Alternately, the caisson is supported on a number of layers of freezable material with each layer being separated by a freeze panel having means for directing a coolant in heat exchange relationship to the freezable layer.  If it is desired to separate the caisson from the frozen soil layer, warm fluid is directed in heat exchange relationship to the soil layer to break the bond between the caisson and the soil layer, whereupon the caisson can be rendered buoyant and floated away to a new site.
