Abstract: ABSTRACT OF THE DISCLOSURE     A device for the synchronization of a local timing signal to permit the demodulation of a differential phase-modulated carrier in synchronous data transmission systems. On the basis of a limited signal of the modulated carrier and a timing signal whose frequency is equal to quadruple that of the carrier, a logic element circuit comprising EXCLUSIVE-OR gates and synchronized flip-flops carries out a sequence of correlations and supplies pulses representative of the position of the phase jumps. These pulses are only used for bringing about the phase and frequency dependency of the local timing signal.

Abstract: Abstract An electric typewriter includes a RAM memory for storing selected characters to be printed and for storing data relating to the present escapement position and future es-capement destination of a print head of the typewriter. A control unit operates a printer to print the stored charac-ters in the memory unit and, when a power interrupt occurs and power is subsequently restored, the control unit ac-cesses particular position data in the memory in accordance with the angular position of a print shaft of the type-writer at the time of the power interrupt.  The accessed data is employed to define a proper return escapement posi-tion for the printing head of the typewriter.

Abstract: ABSTRACT           Water soluble triazole dyes are prepared diazotizing a 2-(4-aminophenyl)-2H-naphtho[1,2-d]triazole sulfonic acid and coupling the result-ing diazonium salt to a barbituric acid. The resultant triazole dyes are compounds having the structure:                  wherein M is H, Na, K, Li, N(R)3H and R is H, lower alkyl or lower hydroxy alkyl and R1 is oxygen, sulfur, imino, lower alkylimino, cyanimino and car-bamoylimino.  The triazole dyes are useful as fluorescent greenish-yellow paper dyes and, as such, exhibit excellent substantivity and tinctorial strength as well as very good properties from the standpoint of bleachabil-ity and fastness to light and bleeding.

Abstract: Abstract of the Disclosure A microprocessor controlled subscriber line circuit for inter-facing analog telephone lines and trunks to a digital switching system is disclosed.  All processing of incoming analog signals is accomplished by the line circuit, including the interface between the line and a digital switch-ing matrix, measuring, monitoring, testing of the signals associated with the speech path, generating talking battery, ringing and other tones, equalization and providing the two-wire to four-wire conversion with acceptable echo performance and minimized cross-office transmission loss.  The analog-to-digital and digital-to-analog conversions are accomplished under micro-processor control as are the tone and power generation functions in a programmable power supply configuration utilizing pulse duration Modulated feedback control in a programmable signal generator.  The described subscriber circuit is particularly advantageous in that it is designed to maximize its implementation using solid state circuit techniques and LSI devices as opposed to conventional audio components and relays.

A beam is secured to each side of the base adjacent the outer edges thereof and a wheel mount-ing assembly is mounted on each beam approximately half way along the length thereof and adjacent the front end of the wheel channel.  The wheel mounting includes a mounting block supported vertically in each beam having a vertical bore formed therethrough into which a cylindrical support enga-ges in adjustable relationship with the block.  An axle bearing surmounts the wheel support and a wheel axle spans the wheel channel and engages within the axle bearings above the plane of the beam with a wheel mounted on the axle.  The lower perimeter of the wheel extends below the lower surface of the base.  A spreader bar extends transversely between the two rear and parallel portions spanning the wheel channel rearwardly of the wheel and small bogie wheels are mounted inboard of the rear portions adjacent the rear ends thereof.          In one embodiment, the wheel is adjustable vertically by hy-draulic pressure so that the degree of penetration of the wheel can be controlled within limits to suit the landing or take-off surface conditions.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus is disclosed for assembling a frameless, relatively thin and torsionally flexible shadow mask and four relatively thick and inflexible mask-suspension braekets.  The apparatus, which is for use in the manufacture of color television cathode ray picture tubes, provides for conforming of the brackets to the contour of the skirt of the mask, and the welding of the brackets thereto.  The brackets according to the invention have a planar central section and two arms for the embracing of and attachment to the skirt around the corners of the mask.  Each bracket has at least one region in each arm adjacent to the central section that is perforated to decrease the cross-sectional area of the region and thus increase electrical resistance of the region.  When an electrical current is applied through the bracket, the magnitude of the current and the reduction in cross-sectional area of the region is effective to selectively resistively heat the region to a plastic state whereby the bracket can be conformed to the desired contour of the music without spring-back and without the deforming the mask.  The method according to the invention provides for conforming the contour of the bracket to the contour of the mask.

Abstract: Abstract:            An apparatus is provided for livestock obstetrics.  The apparatus bears against the body of the dam, a leg sling is placed on the offspring, and two slides can progressively be moved along a rod to tension the leg sling.  To move the slides, a tensioning lever is hinged to one slide, and an intermediate lever is hinged at a different location to the one slide and is also hinged to the other slide.  The inter-mediate lever is in two parts normally held together by spring tension, but if an excess load is applied by the tensioning lever the spring tension is overcome and the parts separate, whereby maximum permissible tension between dam and offspring is not exceeded.  To completely release the pull on the off-spring, the tensioning lever can be moved to release both slides.
