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 made suit-able for processing in reduced crude conversion processes by preliminary contacting with a sorbent containing a metal addi-tive to immobilize vanadium pentoxide deposited on the sorbent material.     It has been shown previously that as the vanadium pentoxide level builds up on the sorbent, the elevated temperature encountered in the regeneration zone causes the vanadia to flow and form a liquid coating on each particle.  Any interuption of particle flow results in coalescence between the sorbent par-ticles.  Once coalescence occurs, fluidization becomes diffi-cult to reinitiate. This results in stoppage of flow in the cyclone diplegs, ineffective operation of cyclones, rapid increase in loss of the sorbent, finally resulting in unit shutdown.            The sorbent can also be made, as we have done, by combining and precipitating other gels with the clay so as to act as a binder for initial utilization until some hydrothermal conditioning occurs.  This binder, such as silica, alumina, titania, zircon-ia, calcia, boria, or magnesia then serves a dual purpose as disclosed herin.            Metal additives, described in this invention, when properly applied serve to form compounds or complexes with vanadia which have melting points above the temperatures encountered in the regeneration zone, thus avoiding the formation of liquid vana-dia and coalescence between particles.  A second method of avoiding vanadia liquidation can be employed by means of select regeneration conditions wherein the regenerated sorbent is recovered in a partially coked state.  In this case, the deposited vanadia is held in a lower oxidation state, the oxides of which have melting temperatures above those encount-ered in the regeneration zone.

Abstract: ABSTRACT OF THE DISCLOSURE     A process and apparatus is described for the production of caps or so-called overcaps particularly for wine bottles, of the type having a tear strip for separating an end portion of the cap from the skirt.  In accordance with the invention, caps are first injection molded, and are then passed to a multi-spindle machine which receives the caps on rotatable spindles, and which successively pierces the end of each cap to form perforations, prints the skirt portion of the cap, and then cuts the tear strip in the cylindrical wall of the cap.  The tear strip is cut by a special knife having cutting edges which are spaced apart by an amount equivalent to the tear strip width, the cutting edges having a part circular sickle shape so as to contact the cylindrical wall of a cap and to form parallel lines of weakness therein while the cap moves between two stations of the rotary head machine.  The major portions of the cutting edges are serrated, hut adjacent ends of the knife edges have a connecting portion which is unserrated and is arranged to cut through the cylindrical walls to form an outer end of the tear strip.

Abstract: ABSTRACT               Animal Bedding Material This invention provides for the bedding of animals, including chickens, on litter consisting of a layer of short strips or pieces of absorbent non-toxic paper.        The paper, for example in the form of newspaper sheets, is shredded and the shreds are then cut into short strips or small 'diced' pieces which are used as the bedding material and which have a size distribution such that the pieces congeal and form a surface crust or cake at an early stage of use and subsequently break up to form a readily friable material.  The layer may take the form of a 'top dressing' covering an existing bedding material to extend its useful life.

Abstract: ABSTRACT        The application describes digital signal processing of radar video signals to provide an optimum display.  Three interacting components of the system are further described in detail:  a global mean estimating circuit, a statistical analyzer circuit, and a dynamic range compression circuit.      The global mean estimating circuit determines the mean of the amplitude distribution of video signals over a wide section of the display as opposed to a local mean of signals. local mean of signals is the mean of the amplitude distribution of video signals occurring in the near vicinity of a point on the display.  The statistical analyzer circuit evaluates the amplitude distribution of video signal samples and controls the gain of the signal path so that the variance of the sampled amplitude distribution follows the variance of a model distribution.  The dynamic range compression circuit functions to compress the range of amplitude distribution in a manner to provide maximum information from the display.

Abstract: ABSTRACT OF THE DISCLOSURE           A support structure, especially for use in under-water work, comprises a hollow pillar, which downwardly merges into a reversed funnel structure, having a base area selected with respect to the expected load and to local ground con-ditions.  The funnel structure and part of the pillar are to be filled with macadam, or other material with internal friction, and the base angle of the funnel structure is slightly larger than the natural angle of repose of the frac-tion of friction material used.  After a possible vibration of the macadam the funnel structure will be completely filled, whereby the load upon the pillar will be transferred to the cone of macadam and be distributed over the bottom surface, below the funnel structure.  The latter may along its lower edge be provided with a serrated skirt suited to enter into a soft bottom.

Abstract: Abstract TWT Interaction Circuit With Broad Ladder Rungs A slow-wave circuit suitable for a high-frequency traveling-wave tube has an array of metallic ladder rungs extending transversely across an elongated envelope and not in contact with the envelope except at the ends of the rungs.  The envelope has a cross-shaped section to provide a fundamental backward wave.  The rungs preferably have aligned apertures to pass a beam of electrons in traveling-wave interaction with the circuit.     By making the rungs transversely broader than a critical value, the lowest passband of the circuit has poles of impedance at both its ends, whereby more efficient interaction is obtained, along with greater stability.

Abstract: Abstract A cutting segment for stone and the like, the segment having a porous center section.  A conventional mixture of cement and diamonds is made, and a quantity of filler is added to the mixture.  The filler will withstand the sintering process, but subsequently falls out so pores are provided.          A segment is made with only the center porous, while the side sections are as dense as is conventional.  The result is that the porous section can receive coolant and/or the resulting slurry for efficient cutting, and the center section wears faster to yield a concave cutting edge.

Abstract: MECHANISM FOR EXTRACTING TAPE FROM A TAPE CARRIER   Abstract of the Disclosure A mechanism for withdrawing magnetic recording tape from a tape carrier (e.g. a cartridge) is disclosed.  A boom member supports at least two levers.  In the at rest (unengaged) position, rollers, supported by the levers, are positioned in a recess in the tape cartridge and are positioned interior of the tape.  When activated, the boom member pivots about its pivot point, thus moving the levers attached to it.  The levers move generally away from the cartridge and the rollers attached to the levers engage the tape and pull tape out of the cartridge.  The roller supporting ends of the levers engage a lever guide member in such a fashion that the at least two levers move apart.  In this manner, a suitable transducer mounted adjacent the lever guide member, can have tape wrapped around itself (less than 360°) for subsequent recording on or playback from the tape.  This mechanism is suitable for use with an internal elastic-belt-drive cartridge; when used with such a cartridge, the reels of the cartridge must be driven in their normal manner when extracting tape from the cartridge.  The cartridge must also be driven in its normal manner when tape is being fed back into the cartridge.  This mechanism is also suitable for use with a non internal elastic-belt-drive cartridge.                             - i -
