Abstract: ABSTRACT OF THE DISCLOSURE         A heat exchanger is disclosed of the type having a gas flue which consists of medium-carrying wall tubes extending substantially parallel to the longitudinal axis of the gas flue and welded together in a gas-tight fashion.  The gas flue terminates at one end by medium-carrying tubes which are also welded together in a gas-tight fashion and which extend transversely of the longitudinal axis of the gas flue.  All tubes terminating at the said one end of the gas flue are connected to the medium side of at least 80% of the wall tubes of the gas flue.  The advance in the art is in that the invention can be used for virtually any cross-sectional shape of the gas flue while avoiding substantial differences in the length of the tubing.

Abstract: Abstract Rotor with Double Pass Blade Root Cooling In a turbine rotor, disk blade root slots around the periphery thereof cooperate with the blade roots disposed therein to define a pair of cooling air passageways across each slot.  These passageways across each slot are in series flow relationship with each other.  Cooling air from upstream of the rotor is fed into one passageway of each slot and flows rearwardly therethrough across the slot.  The same mass of air is then directed into the inlet of the other passageway, which air flows forwardly through the slot to provide additional cooling to the blade roots and disk lugs.

Abstract: Abstract of the Disclosure:         In a method of calling a portable unit from a base station through a radio control channel, a succes-sion of terminating call signals is sent through the control channel from the base station to the portable unit for a first or restricted duration (T1) selected in consideration of a battery saving period of a battery saving operation carried out in the portable unit.          Within the battery saving period, the portable unit is put into transient active and inactive states during a first time interval and a second time interval, respec-tively.  Selection is made so that the first duration be longer than the second time interval to receive at least one of the terminating call signals within the first duration in the portable unit.  The base station monitors an acknowledgement signal for a second duration (T2) after lapse of the first duration and interrupts the control channel when the acknowledgement signal is not received within the first and the second durations.          In the portable unit, the battery saving operation is released when presence of the terminating call signals is detected by a squelch circuit.

Abstract: METHOD AND APPARATUS FOR POSITIONING TRANSDUCERS        BY DIGITAL CONVERSION OF ANALOG-TYPE SIGNALS                 ABSTRACT OF THE DISCLOSURE       Apparatus and method for decoding of transducer head-positioning information which has been recorded on data-storage media, in particular magnetic tape, and for use of the decoded information to position a transducer head, wherein the transducer head reads the recorded information and its output signals are sampled at predetermined times to determine their magnitude and a digital representation of such magnitude it obtained by timing an interval during which a reference source increases at a known rate from a first value to a second value whose difference corresponds to the detected magnitude of the transducer output signals.          The timed interval is outputted in the form of a digital count value which is thus representative of the head-positioning information read out from the data storage media, and the digital signal provided by such count value is then used in positioning, or repositioning, the trans-ducer head in a representative manner.

Abstract: ABSTRACT OF THE DISCLOSURE                 This invention relates to a football type game board utilizing specially designed, dice-like casting solids to represent the various plays used in the game of football.  Each solid or die has a plurality of sides or facets, with markings on each side denoting a particular outcome to that play.  The number of sides and their markings are designed to reflect the range of possible outcomes and their probability of occurring, so that the throwing of the solids in a dice-like manner generates results similar to those which could be expected in a real football game. Also provided is a penalty card system organized into four categories (rushing, passing, kicking and return), so that when a penalty is indicated by the casting solids, selection of a card from the appropriate category will produce a realistic penalty for that type of play.  Also provided is a first down marker system with a down indicator sleeve, for easy player reference.

Abstract: TITLE OF THE INVENTION:            Satellite-Based Position Determination and Message Transfer System With Monitoring of Link Quality ABSTRACT OF THE DISCLOSURE:       A radio position determination and message transfer system is implemented using a number of satellites in geostationary orbit for relaying interrogation and reply signals between a ground station and a user-carried transceiver. Message information can be exchanged between a given user transceiver and the ground station, as well as between different user transceivers. The user transceiver is provided with means for monitoring the quality of the radio communication link between the transceiver and one or more of the satellites, based on errors detected in the received interrogation signals. The transmission of a reply signal by the transceiver is enabled only when the link quality is found to be acceptable. The reply signal may contain message information or may constitute a request for a position fix. In the latter case, the transceiver may be configured to await favorable link quality to more than one satellite before the reply signal is transmitted.

Abstract: Abstract of the Disclosure A method which provides for a permanent planarization layer on a multilayer integrated circuit.  The planarization layer resides above other circuit layers which reflect incident light.   A  layer  of  photoresist  is  formed  over  the planarization layers and imaged through a mask with circuit defining  structure.   During exposure of the photoresist, incident  light  passes  through  the  planarization  layer. Scattering from the boundary of the planarization layer and photoresist is minimized because the index of refraction of the planarization layer is substantially equal to the index of refraction of the photoresist.  Light reflected from the underlying   layers   is   substantially  absorbed  by  the planarization  layer.   Reduction  of  the  reflected  and scattered light results in improved resolution of developed images in photoresist.  The developed images, when further processed  into  interconnecting  conductors  have  improved definition,  avoiding  the  additional  process  steps  of applying a temporary dye or other light impervious layer.
