Title: Process of treating animal fodder
IPC: A23K1/165
Filed: 1934-11-29
Abstract: Animal fodder, e.g. grain and grain offals, green foods, roots and other vegetables, and waste human food products, are dried in a reducing atmosphere, inoculated or activated with enzymes or bacteria, incubated or digested to reduce the hydrion concentration, and then dried to suspend the activity of the enzymes or bacteria without destroying them.  In an example, grass which has been cut fine is fed in a continuous stream into a drying apparatus at a temperature between 15 and 300 DEG  C., through which a stream of carbon dioxide or nitrogen is drawn or blown. The dried product is ground and sprayed with a culture of bacillus, e.g. bacillus prodigiosus tullensi or bacillus proto SS 5 until the moisture content is approximately 30 to 50 per cent. The fodder is now incubated at a temperature not exceeding 35 DEG  C., until the pH value is reduced to about 4.  The product is then dried to suspend the activity of the bacilli without destroying them.  According to the Provisional Specification, an oxidizing atmosphere may be used for the first drying stage, particularly when treating potatoes. Yeasts and bacillus acidi lactici are also specified as suitable for use in the second stage of the process.

Title: Improved methods of Depositing Semiconductor Material and Forming Semiconductor Junctions
Inventor: BLOOM MURRAY
IPC: H01L21/00
Filed: 1967-07-05
Abstract: 1,190,993. Semi-conductor devices. TRW. Inc. 5 July, 1967 [7 July, 1966], No. 31042/67. Heading H1K. [Also in Division C7] Epitaxial deposition of semi-conductor material, such as silicon, on a substrate is brought about by sputtering it from a cathode and depositing it on the substrate through a molten alloy layer supported on the substrate. As solid material is deposited on the substrate from the cooler face of the molten alloy layer further material is sputtered on to its hotter side. A silicon substrate 12, for example, having a thin layer 50 of gold deposited on it, suitably by sputtering, is shielded by shutter mechanism 36 until a discharge between anode 16 and silicon cathode 18 heats it to a temperature at which the gold layer 50 and its surface layers melt together and form a molten alloy of goldsilicon eutectic composition. Shutter mechanism 36 is then opened and silicon sputtered into the surface of the molten alloy, and silicon is deposited at the boundary between the alloy layer and the solid substrate. Silver, copper, indium, tin or aluminium may be used in place of gold. After epitaxial growth is complete the alloy layer is removed, e.g. by soaking in aqua regia, and the material deposited, etched to form semi-conductor devices. By using a cathode of one type of silicon material and a substrate of another silicon junctions can be formed, e.g. PN junctions.
