Abstract: ABSTRACT OF THE DISCLOSURE         Environmentally stable bond joints of aluminum metal and aluminum alloys in adhesively joined structures are formed by utilizing a prebonding anodization of the aluminum surfaces in a phosphoric acid electrolyte using an electrolyte bath temperature of 50°  to 85°F.  The anodized surface is then removed from the electrolyte bath and washed free of electrolyte within from one half to two and one half minutes from cessation of anodizing current, dried and coated with an adhesive resin.          The anodized aluminum metal surfaces are then juxtaposed with an adhesive resin and bonded together under pressure and heat to cure the adhesive resin.  The resulting structure is resistant to failure of the bond joints on exposure to moist atmospheric conditions.  The surface preparation provides a porous hydration resistant aluminum oxide surface which minimizes adhesive failure at the oxide-adhesive interface under aqueous exposure.  Alloys containing copper and other alloying constituents may be successfully anodized and bonded by this process.

Abstract: ABSTRACT OF THE DISCLOSURE     A cylindrical transducer is defined by a pair of con-centric members formed from a suitable material such as quartz and fused at their ends and separated from each other by a rela-tively small distance along an intermediate portion of their axial lengths.  Thin layers of an electrically conductive material are provided on the adjacent surfaces of the concentric members along the intermediate portions of their axial lengths.          The outer member is provided with a progressively increasing thickness near the axial ends of the member.  The thickness of the outer member increases with progressive positions towards the axial ends to prevent the member from cracking when subjected to stresses.         The thin conductive layers on the members are formed by plating a thin layer of a noble metal such as platinum on the annular surfaces of the quartz members and then applying heat to the quartz members at a particular temperature such as approxi-mately 1050°C. for a particular period of time such as approxi-mately fifteen (15) minutes.  This process is repeated several times with successive thin layers of the noble metal to provide a fusion of the platinum to the quartz and to provide a progress-ive change from platinum silicide at the surface of the quartz to platinum at the exposed surface of the conductive layer.

Abstract: ABSTRACT OF THE DISCLOSURE           A control device is described for linking a motor operated data terminal to a data processor which provides information signals including data characters and data terminal motor-start signals.  The motor associated with the data terminal is selectively operable between an on condition and as off condition and is programmed to switch from the on condition to the off condition after a first predetermined interval following the last reception of data characters from the data processor.  The data ter-minal motor switches to the on condition upon receipt of a data terminal motor-start signal and reaches its normal operating speed in at least a second predetermined interval after the receipt of a data terminal motor-start signal. The control device includes means for receiving the infor-mation signals from the data processor and for transmitting such signals to the data terminal.  A first circuit of the control device is responsive to received information signals from the data processor and is responsive to the absence of information signals for the first predetermined interval for providing to the data processor a motor-off signal.  A second circuit of the control device senses the receipt of a motor-start signal from the data processor for providing the data processor with a data terminal busy condition signal of a second predetermined interval.  Following the expiration of the second predetermined interval, a terminal non-busy signal is provided to indicate to the data processor that data characters may be sent.  Accordingly, upon interruption of transmission of data characters by the data processor for an interval of time equal to the first predetermined interval.     the data processor is provided by the control device with a motor-off signal to indicate that a motor-start signal must be sent prior to further transmission of data characters.  Upon transmission of a motor-start signal, the data processor is provided with a motor-on signal and a terminal busy condition signal.  The ter-minal busy condition signal further inhibits transmission of data characters for the second predetermined inter-val until a terminal non-busy condition signal is provided.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of making a friction band for use as either a brake band or a transmission band.  The band includes an elongated metallic strip lined with an elong-ated frictional lining strip.  The strips are adhered to-gether while in a flat or straight condition.  The ad-hered strips are then formed into a generally arcuate shape, with the lining strip on the inside of the arc.          Brackets are welded to the radially outer surface of the metallic strip at each end thereof.  The ends of the lining strip are formed with openings to expose the radially inner surface of the metallic strip to permit electrodes to be applied against the radially inner surface of the metallic strip in directly opposed rela-tion to the brackets, thereby providing a direct path for welding current and making it possible to form a better weld than if no such openings were provided.  This method is simpler and less expensive than adhering the lining strip to the metallic strip after the latter has been formed to arcuate shape.

Abstract: PROCESS FOR THE PREPARATION OF POLYVINYLBUTYRAL HAVING                 IMPROVED PROPERTIES  Abstract of the disclosure:  The preparation of polyvinylbutyral is commonly effect-ed by the acetalization of polyvinyl alcohol with n-butyr-aldehyde, either in an organic solvent or in water.  By varying the reaction conditions it is possible to obtain the polyvinylbutyral in a coarse-grain or fine-grained form.  The production of polyvinylbutyral having improved properties is possible by using a polyvinylbutyral having a content of from 17 to 24 % by weight of vinyl alcohol units as starting material for an after-treatment in the presence of an organic sulfonic acid having an emulsifying effect.  The polyvinylbutyral obtained is particularly suitable for the manufacture of compound sheets.
