Abstract: Abstract:            A high speed modem suitable for operating with a switched network and capable of achieving essentially 9600 bit per second information transfer rate through the switched tele-phone network.  The high bit rate is achieved notwithstanding the variations in the characteristics of the switched tele-phone network by phase and amplitude modulating a plurality of sub-carriers at a relatively low baud rate.  Correlation detection is employed at the receiver to extract or demodulate the information contained in the various sub-carriers.  To allow correlation detection with orthogonal signals, each of the sub-carriers is harmonically related to a fundamental which fundamental is, however, slightly higher than the baud rate.  This allows the receiver to delay correlation for a "gap" time, which reduces the effect of transients produced by modulation and also provides greater tolerance to inter-symbol distortion.  Since the fundamental of all the sub-carriers is higher than the baud rate, the receiver "sees" orthogonal signals during the integration or correlation time which is maintained as the period of the fundamental. In addition to the information sub-carriers, a pair of un-modulated sub-carriers are also transmitted to enable the receiver to maintain the correlation interval in proper syn-chronization with the transmitter, and to correct for phase distortion and frequency offset.

Abstract: SYNCHRONIZING SIGNAL DETECTOR PARTICULARLY         FOR USE IN TELEVISION AFT    ABSTRACT OF THE DISCLOSURE           A synchronizing signal detector for detecting a received television synchronizing signal includes a synchroniz-ing signal separator for separating the synchronizing signal from a received composite television signal.  A phase-locked loop is provided, including an adjustable oscillator and a phase comparator for comparing the difference between the output of the synchronizing signal separator and the output of the local oscillator to produce an error signal.  A sensor senses this error signal to indicate that the output of the synchronizing signal separator is, in fact, the synchronizing signal, when the error signal is of a predetermined value.  In an AFT circuit, the error signal is used to control the tuning condition of the tuning section included in the television receiver.  In one embodiment, the tuning section is an electronic tuner whose tuning condition is determined by a digital count.  This count is changed until the error signal is sensed as being of the predetermined value, whereupon the digital count is inhibited from changing further.

Abstract: ABSTRACT OF THE DISCLOSURE     A bottle transporting table, somewhat like a spoked wheel, revolves about a vertical axis.  A plurality of vertical shafts are angularly spaced around the rim region of the wheel and the top end of each shaft has a bottle supporting turn table fastened to it.  The shafts are journaled on a thrust bearing and a radial bushing fixed in the top of the rim region and the bottom ends of the shafts extend into a cavity at the bottom of the rim which is created by fitting complementarily with a lower stationary ring.  A pair of vertical bores or ducts are formed in the rim parallel to and radially spaced from the turntable shafts and their bearings.  A seal forms an annular channel over the bearings and bores.  A nozzle fed from a pump projects lubricating oil into one of the bores adjacent each shaft as these bores orbit with the rim.          The channel enables the lubricant to be conducted to the bearings and the other bore enables lubricant to be recirculated back to a reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE         Improved process for the preparation of aqueous emulsions of addition copolymers having functional groups to provide thermosetting capability via condensation.  The process improvement  resides in reducing the amount of unwanted premature condensation of the functional group.  The process has two steps, one consisting of polymerizing a portion of the monomer reactants at a temperature not above 60°C if the functional group is present and the other of continuing the polymerization with the addition of the remain-ing monomer reactants at a temperature not above 60°C and at a pH in the range of from 1 to 7.  The process is of use in producing improved thermosetting enamels.

Abstract: ABSTRACT OF THE DISCLOSURE         This specification discloses medical tablets for peroral administration which are adapted to bring difficultly soluble active substances very rapidly into solution, whereby a substantially heightened biological availability is attained in contrast to known, customary tablet formulations.  The invention also relates to a process for the manufacture of such tablets.  A heightened biological availability is of great significance, particularly with difficultly soluble highly active medicines, since they open the possibility of reducing the daily medicinal requirement (maintenance dosage). The disclosed tablet has strongly accelerated liberation of difficultly soluble substances in the gastrointestinal tract after peroral application, which is characterized in that it contains the active substances deposited in finely divided form on a micro-dispersed, amorphous, porous silicic acid with a primary particle size of 1 to 15 µm, a BET surface to 350 to 450 m2/g and a pore volume of 1.4 to 1.7 ml/g.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to a continuous process for manufacturing articles comprised of fiber-reinforced hydraulically bound material.  A layer of the fiber-reinforcing and hydraulically bindable materials are placed on a first endless carrier while a second similar layer is formed on a second endless carrier.  The layer formed on the second carrier is deposited on the layer formed on the first carrier by reversing the second carrier and the composite layer formed as a result is thereafter given the desired shape and is hardened.    A number of fibrous network structures are used with the hydraulically bindable material and the two are formed into a layer with the networks distributed in it.  Water is removed from that layer by suction, while on the second carrier a number of fibrous networks are likewise sup-plied to be formed into a layer comprised of the hy-draulically bindable material with the networks dis-tributed in it and water is also removed by suction from this layer.    The invention is applied in the manufacture of build-ing materials used, for instance, to replace asbestos-cement sheets.

As the temperature of the wall of the mold increases, an adhering layer of viscous polymer is formed thereon while the metal fragments continue to tumble; only when most of the polymer material is in a viscous molten state and has formed a layer covering the inner surface of the mold, the metal particles will adhere to the viscous material layer and form a metal particle monolayer thereon; then, the mold is cooled while still in rotation until the polymer solidifies. Finally, the mold-ed product is discharged from the shell and provides an integral casing substantially consisting of an outer wall of polymer materi-al and a monolayer of metal fragments adhering thereto. Molecular cross-linking of the polymer may be effected by a cross-linking agent and activating the latter after formation of the monolayer.

Abstract: ABSTRACT                BLEOMYCIN ANALOG AND METHOD         Bleomycin's affinity for tumorous tissue and its ability to complex with cobalt has lead to its use in vivo as a complex with 57Cobalt.  This complex has given excellent tumor images and has been useful for diagnostic purposes.  Unfortunately, 57Co has the undesirable property of a 270 day half-life.  The present invention provides a bleomycin analog which has a powerful metal-chelating substituent covalently bound to and chemically modifying a bleomycin.  However, the inclusion of this chelating substituent in the bleomycin analog does not significantly modify the in vivo biological properties thereof with respect to unmodified bleomycin.  The inventive bleomycin analog forms stable chelates with a variety of metal ions, and is particularly useful when labelled with radionuclides having short half-lives.  So labelled, the bleomycin analog may be utilized for diagnostic purposes.
