Title: Improvements in and relating to the production of press board from refuse
IPC: B27N3/02
Filed: 1970-01-31
Abstract: A method for the production of pressed bodies comprises subjecting domestic, agricultural and forestry refuse to form an aerobic fermentation substrate which latter is dehydrated and sterilized to form a dry fibrous granulate of fine structure and of a water content of less than 10% by weight whereafter said fibrous granulate is mixed with a synthetic resin binder and pressed into a pressed body. The aerobic fermentation substrate is dehydrated and stabilized by heating the same to at least 80 C., preferably to 110 C. in a flow of hot air. The synthetic resin binder may be a urea-formaldehyde which may be admixed with a dye or pigment. Other optional ingredients are fire-proofing agents, insecticides, fungicides or thermoplastic materials. In an example the resin treated fibrous raw material is placed in a thickness of 7 cm. on a laboratory plate press preheated to about 130-140 C. and compressed for 12 minutes at a constant pressure of 30 kg./cm.3 to produce a plate having a thickness of 1À5 cm.

Title: Method for fabrication of improved bipolar injection logic circuit
Inventor: AGRAZ-GUERENA JORGE
IPC: H01L21/8226
Filed: 1975-11-20
Abstract: An integrated transistor circuit arrangement provides a multicollector transistor with Schottky diodes and ohmic connections selectively formed at the collector terminals. In the illustrative example, a vertical transistor is formed in an N-type epitaxial layer overlying an N+ substrate. A through-extending region of P+ material encircles the region of the epitaxial layer in which the vertical transistor is formed. The base of the vertical transistor is formed by the implanting of P-type impurity in a location spaced apart from the surfaces of the epitaxial layer. The resulting base has a symmetrical profile relative to the faces of the epitaxial layer. Therefore, the transistor may be operated with the collector at the surface without penalty of electrical operation. In the illustrative example, a PNP lateral transistor is utilized as a current source for the vertical transistor.
