Abstract: TITLE            PIVOTALLY MOUNTED BULLDOZER TEETH ASSEMBLY        ABSTRACT OF THE DISCLOSURE         A set of ripping teeth projecting downwardly from a support frame which is pivotally secured to a bulldozer blade.     The frame extends downwardly from the pivotal support along the front of the blade with the teeth projecting beyond the lower edge thereof.  As the bulldozer moves forwardly the teeth perform a ripping function in the same manner as teeth which are rigidly secured to the blade.  However, as the bull-dozer moves rearwardly, the teeth and frames swing forwardly in a floating motion to prevent the teeth from fracturing and to allow the blade to perform a scraping function.  In one em-bodiment the support frame includes a pair of tubular mounting sleeves formed at opposite ends of its upper edge.  Mounting pins project from the outer ends of the mounting sleeves, and a mounting shaft extends between the inner ends of the mount-ing sleeves.  The mounting pins and the mounting shaft are slidably received by spaced apart hangers which are releasably secured to the blade through blade mounted brackets.  In an-other embodiment of the invention the frame includes a pair of end members each having an ear or a bracket formed at its up-per end which curves rearwardly toward the blade.  Each brack-et releasably receives a respective hanger mounted on the up-per surface of the blade and projecting forwardly therefrom.          The hanger and brackets contain aligned bores through which pin is releasably inserted to pivotally secure the frame to the blade.

Abstract: Abstract of the Disclosure An ultrasonic imaging system comprises a first array of transducer elements adapted to be coupled to an object to be examined, which elements responsive to ultrasonic energy transmitted into the test object intercepting acoustic reflecting surfaces, receive ultrasonic echo signals indicative of acoustic reflecting surfaces in the object.  The received echo signals are converted by the first array of elements into electrical signals which are processed through a time reversal circuit (time inversion) and thereafter used to energize a second array of transducer elements coupled to a reconstruction medium.  The ultrasonic signals transmitted by the second array, responsive to the time-reversed electrical signals, produce in the reconstruction medium a reconstructed image of the acoustic reflecting surfaces in the object.  A visual image of the reconstructed acoustic image is obtained by acousto-optical means, such as a Schlieren device.

Abstract: Abstract A digital electronic spark timing control for an inter-nal combustion engine.  Independent parameters  such as engine speed and manifold pressure are measured and encoded as multibit digital words.  A digital memory stores spark advance angle as a function of two inde-pendent parameters.  The digital memory is addressed by the most significant bits of the multibit words to ob-tain coarse values of spark timing.  Interpolation is performed on the coarse values according to the least significant bits of the digital words to produce the spark advance angle appropriate for the measured para-meters.  Means synchronized with engine position, i.e., top center, convert the spark advance angle to Spark initiation signal.

Abstract: ABSTRACT            Crude oils or residual fractions from the distillation of petroleum containing substantial amounts of metals such as Ni, V, Fe, Cu, Na and high Conradson carbon values are converted to liquid transportation and distillate heating fuels by contact-ing with a zeolitic containing catalyst containing a metal additive to immobilize the vanadium oxides deposited on the catalyst.  As the vanadium oxide level builds up on the catal-yst, the elevated temperatures encountered in the regeneration zone cause the vanadia to melt and liquid vanadia to flow.          Among other things, this vanadia enters the zeolite structure leading to neutralization of acid sites and more significantly to irreversible destruction of the crystalline structure to less active amorphous material (see attached graphs).  In addi-tion this melting and flowing of vanadia can, at high levels and for materials with low surface area, also coat the outside of the microscope with liquid, thereby causing coalescence between catalyst particles adversely affecting its fluidization properties.  The select metal additives of this invention were chosen so as to form compounds or complexes with vanadia which have melting points above the temperatures encountered in the regeneration zone, thus avoiding zeolite destruction, surface sintering and particle fusion.            These select additives were also chosen with a view of immo-bilizing vanadia while simultaneously avoiding neutralization of acidic sites.  Many additional additives which do affect the melting point of vanadia were eliminated due to this negative effect on catalyst activity.  Titania and zirconia, in combina-tion with silica, are known to form acidic catalysts with cracking activity in their own right.  Alkaline earth metals can be used to immobilized vanadia but are somewhat detrimental to acidic sites.  Selection of additives to immobilize vanadia on RCC catalysts is much more confined in comparison but deal-ing with the same problem as vanadia deposited on sorbent materials.            The method of addition of the metal additive can be during manufacture, after spray drying or at any point in the reduced crude processing cycle.

Abstract: ABSTRACT       A light pick-up device for transparency and/or opaque scanning in a drum or flat bed scanning device consisting of a hollow body which has a light entry opening and at least one opening forming the light pick-up surface.  That part of the inside surface which is opposite the light pick-up surface is a diffusedly reflecting reflector and the remaining part may be a mirror or also a diffusedly reflecting reflector.  The light modulated from the master is collected in the light pick-up device, is reflected into the light pick-up surface, and is conducted from there to an opto-electronic transducer means which generates the image signal.  Since the device suppresses the disruptive influence of scratches and shadow edges in the master, a high efficiency and high uniformity of the scanning are achieved with the light pick-up device.

Abstract: ABSTRACT           This invention is an alarm lock which uses a key-releasable cable to secure an article to be protected to a fixed object.  Should the cable be cut, a coded audio alarm is emitted, alerting the owner of the article.  The cable contains a conductor which is connected to an alarm circuit sensitive to a resistance in series with the cable.  Attempts to defeat the cable by jumpering or cutting or otherwise varying the resistance causes the alarm to be set off.  Pulling the cable (tampering) also causes the alarm to operate, for a fixed period of time.  The lock unit can be fixed to the handle bars of a bicycle and the alarm sound can be generated manually whereby it can be used as a horn.
