Abstract: 190,112. Pointe, J., and Navarre, P. Dec. 12, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Bread.-Relates to a process and apparatus for pulping wheat, cereals and other grains, and also stated to be applicable for pulping fruit, to form dough without first grinding into flour. The cereal is placed in a washing and macerating vessel having a central water-supply pipe which induces a water-circulation, the light particles being eliminated through an overflow pipe and the heavy particles settling at the bottom. The cereal is then fed to a hopper a situated above a feeder b<1> and fluted rollers c, c<1>, the rollers hav ing different speeds of rotation. The grains are split and flattened and passed, if desired, between additional smooth rollers c<2>, c<3> before being removed by the worm i. Spring-pressed scrapers co-operate with the rollers c, c<1>. The split grain is passed to a screening device comprising a rotary perforated cylindrical drum rand rubber strips q, helically-disposed, which revolve at a speed different, from that of the drum r, and press the pulp through the perforations leaving the bran within the drum. The extruded pulp is scraped into a trough by a spring-pressed scraper v and the yeast &c. may be introduced therein. Cooling-means for the drum rand strips q are provided. In one form a fan is connected to a pipe which directs air on to the outside of the drum. In modifications, the air is delivered internally from a hollow rotating shaft or through the end of the drum, or a following perforated pipe may be provided for each strip q. Water may be used for cooling, being supplied through a hollow axle and withdrawn through a coaxial return. tube, means for preventing the water from mixing with the cereals being provided. In another modification, Fig. 15, water is supplied through a central tube and is collected in a flanged member 21 and withdrawn therefrom. The rollers c, c<1> may be replaced by helically grooved rollers working in a casing having helical grooves of less pitch, the grains being split and flattened between the rollers and the casing, the helical grooves feeding the material forward. If desired, the whole grain is macerated and pulped without splitting and flattening, typical instances of the temperature of the water, proportion of the water, &c. being stated. The washing and macerating water may contain sterilizing, reducing or oxidizing products.

Title: Method of and apparatus for the incomplete combustion of methane and other hydrocarbon fuels with oxygen, with direct production of mechanical energy
IPC: C01B3/36
Filed: 1953-07-27
Abstract: A gaseous, vaporous or atomized hydrocarbon fuel, e.g. methane, is mixed with oxygen or a gas containing at least 50 per cent. of oxygen to form a combustion mixture containing insufficient oxygen for the complete combustion of the fuel, which mixture is fed to an intermediate container, in which the pressure is maintained at a value at which the mixture is not ignitable, and from thence drawn into an internal-combustion engine, the incomplete combustion of the fuel serving for the simultaneous production of mechanical energy and combustion products such as synthesis gas and carbon black.  As an example, in a four-stroke single cylinder engine operated at 350 r.p.m. with a gas mixture consisting of 40 per cent. oxygen, 58 per cent. methane and 2 per cent. nitrogen maintained in the intermediate container at a pressure of 150 mm. of water, the exhaust products contain 36.5 per cent. carbon monoxide, 55.9 per cent. hydrogen and small amounts of carbon dioxide, methane and nitrogen.  The composition of the mixture in the intermediate container is maintained constant to within \sB 1 per cent. of a predetermined value and a device sounds an alarm if the proportion of oxygen in the mixture exceeds by 2 per cent. a predetermined value and cuts off the oxygen supply if the proportion rises to 4 per cent. above the predetermined value.  An explosion pressure indicating device operates an alarm and also operates a device to feed carbon dioxide into the combustible mixture immediately before it enters the engine if the cylinder explosion pressures rises to 25 per cent. above a predetermined value.  The temperature of the engine cooling water is also maintained constant within \sB 5 DEG  C.  The engine combustion chamber is preferably cylindrical or hemispherical, and if carbon black is the main combustion product desired the engine is run with a low flame temperature by increasing the cooling of the combustion chamber.
