Hydroprocessing of hydrocarbon oils is carried out utilizing a catalyst containing active metal components on a porous refractory oxide and having a narrow pore size distribution, with essentially all pores being of diameter greater than about 100 angstroms, with less than about 10 percent of the total pore volume being in pores of diameter greater than 300 angstroms, and with at least about 60 percent of the total pore volume being in pores of diameter from about 180 to about 240 angstroms. The...

Cereal grains having a moisture content of about 30% by weight are made into masa by radiating with infrared radiation until partially gelatinized. Thereafter, they are ground to a meal. If it is desired to dehusk the grains, this is done by agitating an aqueous slurry as by repeated pumping and surface drying and aspirating the husk before radiation. After radiation, any remaining husks are separated by cracking the radiated grain, sizing the cracked grain, and separating the husks from each si...

Process for treating relatively light colored dates grown domestically to impart thereto the relatively darker appearance, the flavor, the soft-chewy texture and the shelf-stability of imported dates grown in the Middle East region. The process involves applying to the domestic dates a coating of a liquefied composition containing water and an effective amount of at least one saccharide sugar sweetening agent. The saccharide-coated domestic dates are steamed at a temperature and for a period of ...

A cache memory, intermediate a CPU and a main memory, is employed to store vectors in a cache vector space. Three vector address operand registers are employed for reading vector operand elements from said cache memory and for writing results of vector operations back into cache memory. A data path from the cache memory allows vector operand elements to be written into selected local storage registers, and a path from the local storage registers to the cache memory includes a buffer. This appara...

Data points for a sinusoidal waveform are assigned 2 bit values which indicate the state of the amplitude (positive or negative) and the slope of the sinusoidal signal at the particular data point (positive or negative). The 2 bit values for a plurality of sinusoidal waveforms are compared to determine the phase misalignment between the plurality of sinusoidal waveforms.

A cryogenic hydrogen purification system is disclosed which produces low and high BTU substitute natural gas byproduct from a feed stream containing substantial carbon monoxide concentration. The required process cooling is provided by a pair of gas expanders. The purified hydrogen stream can be recycled to a hydroretort. The low BTU substitute natural gas stream contains most of the carbon monoxide. The high BTU natural gas stream forms suitable feed for a hydrogen plant.

A method and apparatus are disclosed for applying foamed material to tobacco, particularly in connection with the making of cigarettes. The foamed material may be added to the tobacco, for example, in the paper guide section of a cigarette maker at the garniture mouth (21) or through the short tongue (30) or through both, or at the chimney (10). Addition of a foamed material to the tobacco, during the cigarette making process, results in a cigarette in which the material added is more uniformly ...

A method of processing soybeans is disclosed which comprises heating raw soybeans in the absence of added water with superheated steam under atmospheric pressure, and cooling the resulting beans by exposure to the atmosphere. This method permits removing any offensive smell fully from the beans without impairing the natural flavor or taste of the beans.

The processing of elastomer gums, which can be natural rubber or synthetic elastomers such as copolymers of vinylidene fluoride and hexafluoropropylene, are improved by incorporating in said gum, along with conventional chemical and compounding ingredients, cyanuric acid or isocyanurate or cyanurate derivatives thereof to improve the processing of such gums, for example, to improve the extrudability thereof or the release of molded articles thereof from the mold.

A process is disclosed for preparing a suede leather product from animal hides. The hide is scalded before tanning and the finished product can be washed and ironed in a manner similar to a woolen garment. The hide is pretanned in formaldehyde, neutralized in sodium bicarbonate, tanned with a basic chrome solution, neutralized with sodium sulfate, and dyed with a direct color dye. More specifically, an outer suede product is obtained from the external corium of the skin, instead of the flesh sid...
