Abstract: ABSTRACT OF THE DISCLOSURE:            Air condenser for condensing vapors where freezing or solidification of the condensate is likely to occur.  Finned tube bundles are used, which are arranged so as to form a primary condensation zone and a secondary condensation zone.          The tube bundles are placed at a slope and are struck by an air stream coming from below.  The innermost tubes are directly struck by the cooling airstream and make up the first condensa-tion zone.  The outermost tubes receive air which has been preheated since it has flowed through the first condensation zone.  These outermost tubes make up the second condensation zone.  Thus vapors which were not condensed immediately are condensed in the second condensation zone.  The apparatus is a compact, self-contained and efficient unit which is cheaper than the prior art devices both as to initial cost and upkeep cost.

Abstract: METHOD AND APPARATUS FOR PRE-DICTING METALLOGRAPHIC STRUCTURE     Abstract of the Disclosure A metallographic structure such as nodularity in castings to be made from molten metal is predicted by causing one part of the sample to rapidly solidify at a first rate and a second part of the sample to solidify at a slower rate.  The temperature of at least said one part of the sample is measured during solidilication.          After solidification of the one part of the sample, the heat conduc-tivity of the sample is used to predict the metallographic structure of the sample.

Title: Method and device for measuring the slope of the envelope delay characteristic of a transmission channel and their application to the automatic equalizer selection technique

Abstract: METHOD AND DEVICE FOR MEASURING THE SLOPE OF THE  ENVELOPE DELAY CHARACTERISTIC OF A TRANSMISSION CHANNEL AND THEIR APPLICATION TO THE AUTOMATIC      EQUALIZER SELECTION TECHNIQUE  Abstract of the Disclosure A method and device for measuring the slope of the envelope delay characteristic in a transmission channel.  The slope is determined from a measurement signal received at the output of the channel.  In accord-ance with the method of the present invention, the measurement signal in the channel has a frequency spectrum that includes three rays at frequencies f0, f1 and f2 which are approximately located in the center and at the edges of the useful passband of the channel, respectively. At the output of the channel, the three components at frequencies f0, f1 and f2 are extracted from the received measurement signal, and the instantaneous phases ?0, ?1 and ?2 of these three components are then measured.  The value of the slope S of the envelope delay characteristic is obtained from the relation            ( 2?0 - ?1 - ?2 - 2?? + ?? + ?? ) where    ??, ?? and ?? are the phases of the three rays at frequencies f0, f1 and f2 of the measurement signal sent over the channel.  When the method of measuring the slope is applied to a data transmission system which employs double sideband-quadrature carrier (DSB-QC) modulation, the measurement signal is generated by causing the carrier to undergo successive phase changes of + .pi./2 and - .pi./2 radians at the signaling rate.  When the method of measuring the slope is applied to a data trans-mission system which uses DSB-QC modulation, wherein the receiver in-cludes a set of fixed equalizers, the appropriate fixed equalizer is selected as a function of the measured slope.

Abstract: ABSTRACT OF THE DISCLOSURE A clamp for clamping objects such as tube, wire bundles, shafts, and the like.  The clamp is formed from two longitudinal strips of resilient soft material, such as a suitable woven fabric or metal, plastic or rubber material, these strips being joined together along their edges by narrow lateral strips of the same material forming resilient hinges therebetween.  One of the longi-tudinal strips is longer than the other and has a tab member clamped to both ends thereof, the tab members being formed of a hard material such as a suitable metal.  The opposing surfaces of the two longitudinal strips which are jointed together are coated with a low friction non-sticking material.  The clamp is wrapped around the object to be clamped with the inner surface of the longitudinal strip not having the tabs attached thereto in firm contact with the object to be clamped, and the tabs secured together with a retaining screw or the like to provide the desired clamping action.  The opposing low friction surfaces of the two longitudinal strips are permitted to slide against each other with movement or expansion of the objects being clamped, thus minimizing the changes of abrasion or other damage to such object.

Abstract: HYPHEN CHARACTERIZATION APPARATUS FOR A TYPEWRITER                Abstract of the Disclosure In a typewriter having text storage capability, the hyphen code that is stored in response to depression of a hyphen key is conditioned on printing position and on the codes adjacent to the hyphen code in a text string. If a hyphen is keyed after the start of the return zone, is preceded by a graphic representative code and is followed by a keyed carrier return, a distinctive hyphen code representative of a syllable hyphen is recorded. Otherwise  a regular hyphen is recorded unless the hyphen key has been depressed in conjunction with a condition key (e.g. the CODE key), in which case a code representative of a required non-breaking hyphen is recorded.  As a result of so controlling the recorded hyphen codes at the time of keyboarding, the operator's intentions for hyphenation may be achieved with little departure from normal keyboarding routine.

Abstract: ABSTRACT            A shroud support or tube holder is disclosed for use with a teeming vessel having a gate valve.  In the instance disclosed, the gate valve is a sliding valve, and the shroud is positioned by means of a boom in pour tube relationship with the nozzle of the valve.  The boom is pivotally mounted for rotation in a horizontal plane, and axially slidable for elevation and lowering. The boom is urged upwardly by means of a dead weight system which, when translated to the length of the boom to a shroud holder, permits the shroud to be engaged with the pour tube portion of the vessel at a predetermined load. The means for pivoting the shroud or tube for removal from the vessel which is being filled has a locked position to lock the shroud against lateral movement which can multiply the internal forces and crack the internal nozzle, and yet can be pivoted at an angle for easy removal from the vessel.       The method contemplates positioning a shroud against the lower portion of a pour vessel and secured in place by means of prede-termined dead weights.  In addition, the method seeks to inhibit any lateral or multiplied force loads on the nozzle by means of locking the shroud in a coaxial pour relationship with the nozzle of the vessel.

Abstract: CLAMPING DEVICE FOR SELF-SUPPORTING ELECTRIC CABLES   Abstract of Disclosure A support for electric cables in instances where the configur-ation of the distribution system is not fixed, or permanent, or situations of the same general character prevail. The cable is clamped between a pair of cable clamping members. The outer surfaces of the cable clamping members form wedges guided by a pair of con-verging flanges. The inner surfaces of cable clamping members clamp the point or region of a cable that is intended to be held fixed in space. A pair of outer clamping members surround the above flanges. Tie means ensure that all parts of the structure always stay in their proper relations, allowing but a widening, or narrowing, of the cable receiving channel. The above flanges have projections or abut-ments which enter into lateral elongated recesses of the cable clamp-ing members and thus limit the possible minimum and maximum spacing of the latter, which depends upon the size of the electric cable that is intended to be supported.
