Abstract: RANDOM LAID BONDED CONTINUOUS   FILAMENT CLOTH AND METHOD AND APPARATUS FOR MAKING SAME                     James B. Sisson ABSTRACT OF THE DISCLOSURE This application discloses a cloth structure comprising preferably generally continuous melt spun organic polymer filaments dispersed and laid to provide frequent random filament crossings, subsequently bonded to form a coherent cloth.  In accordance with one aspect of the disclosed invention, a stream of filaments is melt spun through a linear spinnerette having a plurality of spinnerette orifices or rows of orifices offset to enable interleaving of the extruded filaments into a planar single row stream of filaments which are mechanically drawn to textile denier while still arranged in such single row stream on a draw roll having its surface in alignment with the axis of the spinnerette and then forwarded in such single row stream to a formation location closely coupled with a porous collection surface whereat the filaments are dispersed randomly or in directed formation onto the porous collection surface.  In accordance with this aspect of the invention the controlled spinning, drawing and forwarding and the close coupling provide a precisely defined focus or divergence point for laydown of each filament in the stream and a limited and controlled excursion of each filament symmetrically about its focus.  In accordance with another aspect of the disclosed invention at least some of the dispersed filaments are random laid to form an unbonded web on a porous woven fabric having generally uniform knuckle heights and the unbonded web comprised thereof is carried while still on the fabric and together therewith through a heated bonding nip to emboss the fabric knuckles into the web, providing spaced apart spot bond points and a textured surface to the bonded cloth produced thereby.  In accordance with yet another aspect of the dis-closed invention, there are provided at least two types of preferably generally continuous filaments, at least one of which is relatively elastomeric, at least one of which is generally uniformly dispersed and random laid to provide frequent random filament crossings, at least some of which are bonded, preferably autogenously, to form a coherent bonded cloth.  In accordance with this aspect of the invention the fibers are selected to have differing stretch characteristics such that, under a given common percent elongation, inelastic or permanent deformation will be produced in at least one fiber type in the cloth and elastic or non-permanent deformation will be produced in at least one other type of fiber in the cloth.

Abstract: UNDERSTEER VEHICLE STEERING SYSTEM       A B S T R A C T     A system for producing understeer characteristics in an articulated earthmoving vehicle.  A fluidic accelerometer continuously senses lateral acceleration of the vehicle to modify the operator's input signal, causing hydraulic jacks to articulate the vehicle in such a manner as to exhibit an understeer steering characteristic.  The accelerometer is mounted at or near to the roll axis of the vehicle to minimize the effects of vehicle roll dynamics upon the signal communi-cated to the steering control system and hydraulic jacks.          The accelerometer and hydraulic jack control assemblage is utilized to create understeer characteristics in both follow-up and non-follow-up type steering systems.

Abstract: PROCESS FOR PREPARING FINELY-DIVIDED REFRACTORY POWDERS     Donald R. Carson and Calvin B. Holden ABSTRACT OF THE DISCLOSURE         Helical flow of hot plasma gas, e.g., hydrogen gas, produced by a gas vortex stabilized plasma arc is cancelled by introducing attenuating gas, e.g., hydrogen gas, into the hot plasma gas in a manner such that the attenuating gas assumes a vortical direction opposite to the helical flow of the hot plasma gas.  The resulting gas stream is well-collimated.  The well-collimated plasma gas stream is used in the preparation of finely-divided refractory metal and metalloid carbides, borides, nitrides, silicides and sulfides.  Reactants for the preparation of the aforementioned refractory powders are introduced into the collimated plasma gas stream.  The reaction is conducted in the gas phase within a reactor and solid, finely-divided refractory powder removed from the reactor.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a data processing arrangement, comprising two sub-assemblies which are provided in two channels and which are controlled stepwise by a common timing current supply which emits at each processing step, in addition to a number of control signals, a monitoring pulse for scanning comparators connected in series for each two comparable signals from the two channels.  The comparators apply to the timing current supply, when appropriate signal pairs are present, the monitoring pulse, as fault-free signal, for initiating the control signals required for the next processing step, and a further monitoring pulse.  Two micro-computers are fed from two unidirectional voltage sources independent of one another, of the micro-processors of which micro-computers equivalent connecting pins for addresses, data and control signals to be emitted are connected in pairs to respective comparators.  There is provided in the timing current supply for the dynamic signals a monitoring unit which disconnects the unidirectional-voltage sources in the absence of the error-free signal.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to an improved container which may be easily opened and closed and which may be used as a transparent merchandise container.  It has a bottom member and an identical removable top member which are interlocked by closure mechanisms provided on each side of the container.          Each of the closure mechanisms has a number of upper tab members which extend downwardly to resiliently engage a lower horizontal lip on the bottom member and a number of lower tab members which extend upwardly to resiliently engage an upper horizontal lip on the top member.  In the closed position, the upper and lower tab members of each closure mechanism are located horizontally adjacent in alternating positions along the closure mechanism.  The container may be manually opened by releasing one of the closure mechanisms by "pinching" the upper and lower tab members between the thumb and forefinger of one hand and pivoting the top member about the other closure mechanism until it may be removed.  This may also be done mechanically.          The container also provides improved features for nesting of the empty members during shipping to reduce scratching of the top, bottom and side surfaces, as well as for stacking or hang-ing of the containers on display.  The top and bottom members are injection molded from a suitable plastic material using a single form and thus the improved container may be manufactured with great economy.

Abstract: Abstract of the Disclosure Apparatus for validating a card having posi-tioned thereon a plurality of redundant encoded blocks of data readable by moving the card past a reader and for controlling the movement of such a card whose valid-ity is to be determined.  A card transporter moves a card along a predetermined path.  A reader senses each block of data on the card as it moves forward along the path from an entry position to a dwell or escrow posi-tion and supplies an electrical signal representative of the data in each block.  A card validator responsive to this signal compares data derived from at least one block thereof with a preselected set of data in making the validity determination.  The validator includes circuitry for combining the data from at least one block with a prior set of data to produce a stored resultant set of data, and for comparing it with a preselected set of data and for supplying an indication of card va-lidity if these sets of data are identical.  If the card is not determined to be valid, the card transporter re-turns it to the entry position.  A valid card remains in the escrow position pending either subsequent collec-tion thereof or the return thereof.

Abstract: ABSTRACT OF THE DISCLOSURE A predictive encoder for producing a prediction error signal in response to an autocorrelated signal of the same type as a television broad-cast signal compares at least three prediction signals to produce a selection signal indicative of each of at least two of the prediction signals which give a better approximation of the autocorrelated signal than the remaining prediction signal or signals.  The encoder selects the at least two prediction signals according to the selection signal, again selects one of the at least two prediction signals according to the prediction error signal, and sends the selection signal together with the prediction error signal. A predictive decoder for use in combination with the encoder reproduces the prediction error signal and the selection signal, produces at least three prediction signals corresponding to those used in the encoder, selects at least two thereof according to the reproduced selection signal, and again selects one of the last-mentioned at least two prediction signals according to the re-produced prediction error signal.  Preferably, one of the at least two predic-tion signals is a predetermined prediction signal.  At the beginning of pro-duction of the prediction error signal and reproduction of the autocorrelated signal, selection is preferred of a preselected one of the at least two prediction signals.

The cooling gas as it circulates will entrain thermopar-ticulates produced in the system when there is overheating.          This gaseous carrier is then withdrawn and conducted to an ionization chamber where it is ionized.  Downstream from the ionization chamber there is placed a first ion collector for collecting ions with relatively small radii.  A second ion collector which is biased for collecting ions with rela-tively large radii is also placed downstream from the ioni-zation chamber.  By comparison of ion current from the first ion collector with ion current from the second ion collector it is possible to detect the presence of thermoparticulates in the cooling gas relatively independent of gas pressure, flow rate through the monitor, and effectiveness of the radiation source.
