Abstract: ABSTRACT OF THE DISCLOSURE      An aircraft is provided utilizing a spherical balloon filled with buoyant gas such as helium at a pressure substan-tially greater than atmospheric so that its dimensions are substantially unaffected by changes in atmospheric pressure or temperature.  The aircraft may take the form of a self-propelled and self-contained airship, or may be merely a passive device for providing lift and intended to be towed by and controlled from a helicopter.  The spherical balloon is mounted on a normally horizontal axle having end portions projecting from opposite sides of the balloon, and includes a rigid load supporting  yoke   including two arms extending upwardly from a central load supporting structure and each with an upper end suspended from the axle.

Abstract: CONTROLLED D-C POWER SUPPLY            Abstract:    By controlling the phase angle at which conduction occurs in the SCR's in an SCR rectifier bridge, a d-c voltage of adjustable magnitude may be produced from a-c line voltage applied to the bridge.  The specific angle at which the SCR's are fired into conduction during each half cycle of the a-c line voltage is determined by comparing a ramp-shaped pulse, produced from the line voltage during each half cycle, with an error signal which varies as a function of the difference between the desired d-c magnitude and the actual amplitude of the d-c voltage.  The d-c power supply is made immune to line voltage variations by re-gulating the ramp-shaped pulses so that they always have the same pulse width regardless of line voltage amplitude, thereby facilitating precise control over the d-c magnitude.

Abstract: TRANSMISSION OF ADDITIONAL SIGNALS VIA LINE ENCODED DIGITAL TRANSMISSION SYSTEMS BY EMPLOYING RANDOM SIGNALLING OPPORTUNITIES            Abstract of the Disclosure At a transmitter of a digital transmission system which uses a redundant transmission code to transmit data, at least one predetermined code combination which occurs randomly in the encoded data is selectively modified, to form a predetermined code violation, in dependence upon an additional signal which is to be transmitted.  At a receiver, the predetermined code violation is detected and corrected to reproduce the additional signal and the data.  By selection of appropriate code combinations and violations more than one additional signal can be transmitted.  The arrangement is particularly suitable for transmission of additional signals, which may comprise protection switching signals or a digital voice channel signal, via fiber optic transmission links using 2AMI encoding.                             - i -

Abstract: 121,403 CAN/REG                       ABSTRACT           The invention concerns pressure-sensitive tape, the adhesive layer of which comprises an acrylic polymer which has been crosslinked by being mixed with a chromophore-substitued halomethyl-s-triazine and exposing the mixture to ultraviolet radiation.  The invention differs from the prior art in that the s-triazine has the formula   wherein each of R1 and R2 is hydrogen, alkyl, or alkoxy. This s-triazine can be made by a more simple and hence more economical process than can the s-triazine of the prior art, tends to provide desirably shortened reaction time and somewhat greater tolerances to oxygen, and produces no observable color versus a yellowish color encountered in the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE      A full or partial rotational, substantially zero friction electrical conductor assembly conducts the electrical currents of a large number of electrical circuits between a pair of relatively rotatable members in a minimum axial length.  A plurality of concentric, annular, radially spaced gaps are formed between corresponding concentric, concave surfaced, electrically conductive rings affixed to the members, such that a large number of circuits may be accommodated in a reduced axial length assembly.  Resilient, filamentary conductor loops are disposed between the conductive rings, and the loops contact, roll on, and are captured by the concave surfaces of the conductive rings, thereby provid-ing electrical continuity between the relatively rotatable members.  The conductor loops are sealed within individual structural enclosures, thus, providing an environmentally clean and rugged assembly.
