IPC: C08F2/00
Filed: 1959-03-17
Abstract: A process for the polymerization of olefins, e.g. ethylene, or gaseous mixtures containing olefins by the dry method, i.e. in the absence of a solvent or in the presence of such small quantities that the polymer is still capable of trickling, comprises carrying out the polymerization using a catalyst which is supported on preformed polymer according to the process disclosed in the parent Specification, wherein the activation of the preformed polymer with Ziegler catalysts takes place in one installation and the polymerization takes place in a separate installation in polymerization reactors which are constantly supplied with product from the activating installation.  The transfer of inert polymer into the activating vessel and of activated polymer into the polymerization reactors may be effected continuously by means of a controlled-feed device such as worm-screw feeds, bucket-wheels or rhythmically operating devices equipped with means for determination of the weight.  The pressure in the vessel supplying the polymerization reactor may be above that in the reactor to prevent back-diffusion of the olefin.

Title: Improvements relating to semiconductor junctions
Inventor: BILLIG ERNST
IPC: H01L21/24
Filed: 1956-03-28
Abstract: 840,426. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 28, 1957 [March 28, 1956], No. 9667/56. Class 37. A junction is formed in a monocrystalline semi-conductor body containing an activator impurity characteristic of one conductivity type by melting a surface region of the body in vacuo so as to evaporate some of said activator therefrom, and then cooling the body in such a way that the molten material, now of different electrical characteristics from the remainder of the body recrystallizes as an extension of the monocrystalline structure thereof. The heating may be effected by radiation or induction or by electron bombardment of the surface region using either a fixed beam or a scanning beam of small cross-section. The opposite surface of the semi-conductor body is preferably cooled by a fluid coolant or by contact with a heat sink so that a temperature gradient perpendicular to the liquid-solid interface is established. To further facilitate production of the monocrystalline structure the liquid-solid interface preferably lies parallel to a closely packed crystallographic plane (e.g. the 111 plane). In one embodiment a surface of a 50 ohm. cm. silicon monocrystal containing 1014 atoms/c.c. aluminium and 2 x 10<SP>14</SP> atoms/c.c. arsenic or phosphorus is melted in vacuo while the opposite surface is cooled. Some of the arsenic or phosphorus evaporates so that a PN junction is produced on cooling. As a result of the directional cooling the recrystallized region has the form of a cone at the base of which lies the junction. The top of the cone may be ground off to leave only a thin region overlying the junction. If desired a PNP junction body may be formed by repeating the process on the opposite face of the crystal. Alternatively such a body, suitable for use in a transistor, may be made by forming the two PN junctions simultaneously on opposite faces of the crystal by melting the opposed faces while the intermediate part of the crystal is cooled. NN + and PP + junctions may also be formed by similar processes. The use of germanium and A III B V  compounds in conjunction with the acceptor materials boron, aluminium, gallium, indium and gold, and donor impurities phosphorus, arsenic and antimony in carrying out the invention is also suggested.
