摘要： A process and apparatus are described for agglomerating metal-containing fine sized particles of metallurgical waste materials continuously by means of a combustible agglomerating agent. The process and apparatus may be adapted to dust and fine particles of different origins and having any particular particle size range and bulk specific gravity. The agglomerates are obtained by feeding the dust or fine sized particles and a combustible agglomerating agent to a continuous mixer, then to a heated rotatable kiln. The agglomerates are subsequently allowed to fall onto one or more conveyor belts, arranged in sequence. The agglomerates on the conveyor belts may be cooled, either by water or compressed air jets impinging upon them, or by cooling the belt surfaces on which the agglomerates are carried. The agglomerating agent may be a low melting point hydrocarbon such as wax, tar, pitch, or the hydrocarbon may be emulsified with water to form an emulsion and then mixed with the particles.The agglomerates may also be extruded after mixing, by having conventional extruding means incorporated in the apparatus.

摘要： A process is described for the agglomeration of fine particles utilizing a combustible agglomerating agent dispersed in an aqueous emulsion. The process is particularly directed to the handling of fine metal containing particles, originating as by-products or waste products of metallurgical processes, which are to be stored or recycled to metal extractive process steps. The amount of agglomerant added as aqueous emulsion to the particles, is calculated by correlating in an empirical formula the bulk density and the average particle size of the particles, with the emulsified combustible agglomerating agent to be added expressed as weight percent of the particles. The calculated amount of combustible agglomerating agent is emulsified in water, then mixed and blended with the particles, which usually comprise particles of non-uniform size distribution. The aqueous emulsion may also be formed in-situ on the surface of the particles, and the mixture is then blended to form agglomerates. The mixture which is advantageously at a temperature above the ambient, is allowed to cool and be compacted by its own weight. The dust free agglomerates obtained may be stored or charged directly to smelting or refining process steps.

摘要： An ABS system has a plurality of brake channels receiving apply pressure directly from a pump without an accumulator during ABS operation. To assure sufficient pressure for all channels during ABS reapply modes the channels are multiplexed to apply one at a time and keeping on hold other channels scheduled for apply. Several states of brake application are identified and the states are prioritized for each channel so that the multiplexing is ordered according to channel priority.

摘要： A brake pedal contacts a pin holding the push rod for the master cylinder, applying the hydraulic service brakes in the normal manner when the pedal is depressed. When the transmission lever is shifted into the park position a solenoid type servo is energized, engaging a pawl, mounted on the brake pedal, with a gear sector pivoted about the pivot point of the brake pedal. A one-way spring clutch is energized to hold the link in which the push rod pin is installed in the applied position during parking brake apply, retaining hydraulic brake pressure during that operation. When shifting to park, the brake pedal is raised by a vacuum servo so that the pedal can be actuated to apply the parking brake without contacting the push rod pin, and therefore without hydraulic pressure resistance. Movement of the pedal with the pawl engaged exerts tension on the parking brake cable through the gear sector to apply to parking the brake. When the ignition key is turned off, the spring clutch is released and the hydraulic service brakes are released. The pawl is retracted when the ignition key is turned off, and another spring clutch prevents release of the parking brake. This clutch is released upon shifting the transmission lever from park. A circuit is provided which prevents reengagement of the pawl until the transmission lever is shifted out of and then back into park.

摘要： A strip of shoe rim steel has holes punched, and lining is molded to it in segments with a flat or curved top, the strip then being bent at locations between the lining segments and remaining flat so as not to destroy the bond. The assembly is trimmed to length, the web attached and the lining pads ground to final dimensions. The number and length of lining pad segments can be varied. The lining can be used down to the rim ends at each pad while the pad center still contains lining where the molding holes are located.

摘要： The support for the outboard disc brake lining is a section of the caliper, and no shoe is used. The lining has a boss which fits into a recess formed in the caliper housing. The boss has sufficient shear area to transmit brake torque to the caliper. Center holes in the lining provide a location for a clip to be installed through the outboard caliper section. The clip keeps the lining away from the disc in the rest position and may also function as a lining wear sensor. The results include lighter weight and more usable lining.

摘要： An areal array of tubular electron sources is disclosed for producing multiple directed electron beams. Sources (10) are located in a parallel array between a conductive back plate (12) at a closed end of the tubes and a conductive face plate (14) having holes therein aligned with the second open end of each of the electrode tubes (10). An electrical current source (30) is connected between the back plate (12) and face plate (14) to resistively heat each of the sources (10) to a temperature high enough for thermionic electron emission. Electron beams (34) are produced from within each of the tubular electrodes (10). Extraction means which may include a magnetic field from a coil (29) and an extraction lens (18) tends to withdraw the electrons from within the sources (10) in an intense, collimated beam (34). Beams (34) are accelerated toward a target (28) through a beam deflection unit (22) having holes (24) associated with each of the electron beams (34 ). Beam deflection plates (26) within each of the holes (24) deflect the electron beams (34) to impact selected points on a target (28).

摘要： A vehicle brake booster and master cylinder assembly has a vacuum suspended booster section which is controlled by movement of the vehicle brake pedal. A hydraulic booster section is in series with the vacuum suspended booster section, and a master cylinder unit is in series with the hydraulic booster section. The assembly is so arranged that in normal operation the vehicle operator obtains booster brake actuating pressures by operation of the vacuum suspended booster which acts through the hydraulic booster mechanism without operating the hydraulic booster. When greater brake actuating pressures are required, as indicated by increased brake pedal force exerted by the operator, the vacuum booster reaches its limit or run-out condition and the hydraulic booster is operated so as to continue the increase in master cylinder output pressure. If still further master cylinder output pressure is required when the hydraulic booster has reached its run-out condition, the master cylinder is actuated manually through mechanical force transmitting elements which are parts of the booster sections. The vacuum suspended booster section is connected to the vehicle engine intake manifold as a vacuum source, and the hydraulic booster section is connected in the hydraulic power steering gear system so that hydraulic pressure for its operation is generated by the power steering gear pump. The assembly is so interconnected that the master cylinder can be operated manually when there is no or insufficient power pressure to operate either booster section. It may also be operated by actuating the vacuum suspended booster section, and, when no hydraulic pressure is available to the hydraulic booster section, this operation may be followed by manual actuation. It may be operated by initially actuating the hydraulic booster section when there is no vacuum available for initially operating the vacuum suspended booster section, followed by manual actuation as needed. In one embodiment the assembly utilizes a single hydraulic fluid for the hydraulic booster section and for the master cylinder and brake apply circuitry. In another embodiment the hydraulic booster section is operated by a separate fluid circuit which is fluidly independent of the master cylinder and brake apply pressure circuitry.
