Patent ES-429630-A1 (ES)
Title: Apparatus for milling grain while simultaneously cooking the grain
IPC: A23B9/02
Filed: 1974-08-29
Abstract: A method and apparatus for milling grain while simultaneously cooking the grain in which the grain is introduced between coaxial relatively rotatable grinding members and advances therebetween while being milled. The milling of the grain develops heat in the grain which converts the moisture therein to steam which effects cooking of the grain. Most, if not all, of the steam thus generated is reabsorbed by the milled grain as it emerges from the apparatus. In order to enhance the cooking effect on the grain, the outer one of the conical grinding members has a heated gaseous medium supplied thereto and the mill includes an impeller for forcing the gaseous medium through the inner one of the grinding members so that both of the grinding members are heated and thereby enhance the cooking of the grain being milled in the apparatus.

Filed: 1974-09-05
Abstract: An improved process for preparing elastomeric block copolymers of the formula A-B-A, wherein A is a poly-alpha-methyl-styrene polymer block, and B is an elastomeric polymer block from a conjugated diene. Alpha-methyl-styrene is polymerized by means of a mono-functional anionic initiator and an activator with an initial monomer concentration in excess of 100 g of alpha-methyl styrene per liter of reaction mixture, at a temperature of between 0 DEG and 40 DEG C, the amount of said activator being present such that the molar ratio of activator/initiator ranges from about 0.1 and 35 for a polymerization time of no more than 120 minutes. Thereafter, a small amount of conjugated diene and/or styrene is added to the reaction mixture. Subsequently, a conjugated diene is added to the mixture and polymerized. A bi-block copolymer consisting of a poly-alpha-methyl-styrene block and a poly (conjugated diene) block is formed. Formation of the A-B-A block copolymer occurs through addition of a linking agent to this block copolymer of alpha-methyl-styrene and conjugated diene.

Patent ES-462635-A1 (ES)
Title: Connector for connecting a circuit element to the surface of a substrate
IPC: H05K7/10
Filed: 1977-09-26
Abstract: A two part connector system for connecting a circuit element such as an integrated circuit chip to the surface of a printed circuit board in which the first connector section, e.g., a chip carrier, which holds the circuit chip, has resilient, spring-like external terminals which can be connected directly and permanently on the printed circuit board surface, as by soldering, without appreciable risk of breakage of said connections because of different expansion and contraction coefficients of the chip carrier and the printed circuit board or, alternatively, the chip carrier can be removably mounted in the second connector section, e.g., a socket, which also has resilient, spring-like external terminals connectable permanently to the surface of the printed circuit without appreciable risk of breakage of said connections because of different expansion and contraction coefficients of the socket and the circuit board. Such a two-part connector structure enables a ceramic encapsulated circuit chip having a first coefficient of thermal expansion to be safely and advantageously mounted on a plastic printed circuit board having a substantially different coefficient of thermal expansion. Economies of space and higher frequency capabilities are obtained by the structure of the invention over that obtainable by conventional dual in-line packaging techniques.
