Abstract: A method for real-time authentication or authorization of a user (1) of a secured system (3) is based on using two authentication channels and an authentication device (4) from which the secured system can request authentication or authorization (6) over a secured information network connection (6, 9). One of the authentication channels is a telephone network (8), to which the authentication device (4) is connected. A user logging into the secured system (3) over the other channel (6) of the authentication channels must make a call to the authentication device over the telephone network by his or her telephone (2). The authentication device verifies that a call has been received from a telephone number of the user's telephone, and issues a positive verification response to the secured system. Upon receiving a positive response, the secured system provides a requested service through the other channel.

IPC: C04B35/468

Granted: 1956-04-23
Abstract: 776,568. Ferroelectric materials. AMERICAN LAVA CORPORATION. Dec. 9, 1954 [Dec. 11, 1953], No. 35714/54. Class 37. [Also in Group XL (b)] A method of activating a ferroelectric ceramic comprises (i) applying an activating current to the ceramic with the ceramic heated to not more than 10‹ C. above its transition temperature and (ii) continuing to supply the activating current whilst allowing the ceramic to cool. The term " activated " means treatment to produce increased dielectric constant. The term " transition temperature " means the temperature at which the first crystal transformation above room temperature is effected. The current is D.C. and is preferably that which produces a change of at least 15 per cent and more preferably the maximum change in dielectric constant. The current may be maintained. substantially constant while the ceramic cools to at least 65‹ C. below its transition temperature. The maximum change in dielectric constant for a particular ceramic is found by using sample pieces of the material and subjecting each piece to activation until that current is found which produces the largest. change in dielectric constant.  Detailed embodiment.-A ceramic cylinder 10, shown in Fig. 1, has silver electrode coatings 11, 12 and leads 13,14. The ceramic material comprises 96 per cent barium titanate and 4 per cent lead titanate. A number of such cylinders are immersed in chlorinated diphenyl and slowly heated to 10‹ C. above the transition temperature (120‹ C). A D.C. is then applied to leads 13, 14 and increased gradually until it reaches 14 micro-amperes per square inch of electrode surface. After a short time the temperature is lowered slowly and the current maintained constant by increasing the applied voltage as the cylinders cool to about 65‹ C. below the transition temperature. After complete cooling the diphenyl is removed by dipping the cylinders in acetone. The activating current value of 14 micro-amperes is that which produces the greatest change in dielectric constant for the given ceramic. This value is found by treating groups of cylinders using different current values for each group and measuring the capacity values and compiling results. Fig. 1 has application as a condenser or piezo-electric device. Ceramic materials.-The invention may be performed using the following ferro-electric ceramics : titanates of alkali metals and alkaline earth metals; tungstates, bismuth oxides, strontium cerate, boron phosphate, arsenic sesquioxide, lithium ferrite, lithium sulphate and antimony iodide; also titanate compositions comprising selectively as additives or minor proportions the stannates and zirconates of barium, lead and calcium and the titanates of calcium, strontium and lead.

[Also in Division C6] Brewers' wort is heated to a temperature above 212‹F. under a pressure sufficient to prevent the wort from boiling, and the hot wort is passed through a throttling-device into a flash chamber at a lower pressure where the unwanted volatile substances evaporate from the wort. The amount of evaporation can be adjusted by controlling the temperature and pressure conditions in the two stages of the process. A hop extract is added to wort in tank 10 which is maintained at a temperature of 140‹ to 180‹F. The hopped wort is pumped through jacketed-tube 18 where it is heated to about 300‹F. under a pressure of 75 psi absolute. The inner surface of tube 18 is provided with a scraper. The wort remains in holding zone 12 for about ¢ minute and then flows through pressure-release valve 16 into chamber 20 which is maintained at atmospheric pressure or under partial vacuum. The flashed vapours leave chamber 20 through pipe 22, and the wort flows into zone 24 where it is cooled and freed from precipitated protein. The wort is now ready for fermentation. In cases where hop extracts are used in which the alpha acids are already converted to isohumulons, the extract may be added to the wort in the flashchamber.

Abstract: 1,231,435. Consuming noxious gases; thermal regenerators. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 2 July, 1969 [5 July, 1968], No. 32225/68. Headings F4B and F4K. An afterburner arrangement, for combusting contaminated or polluted gases supplied under pressure by a fan (10, Fig. 1) through an inlet chamber 20, incorporates a rotary regenerator disc 22 located across the top of a combustion chamber 16. The disc 22, which is made of a refractory heat transfer material having a plurality of triangular through passages (46, Fig. 7) therein and which is heated by the exhaust gases leaving the combustion chamber 16 via outlet chamber 35, serves to preheat the incoming contaminated gases up to the required temperature. Seals 36 and 37 are provided to minimize leakage of gas around the disc. A partition 39 separates the inlet and exhaust chambers. Air for combustion, if necessary, is supplied to the chamber 16 from a manifold (201, Fig. 8) suitably located above the disc such that the air also serves to purge the passages in the disc. Fuel gas for combustion can be introduced through a line 50 to a burner 52 in the chamber 16, if required. Alternatively the fuel gas may be introduced through an injector 60 located upstream of the regenerator disc 22. The disc is mounted on shafts 23, 24, the shaft 24 being hollow and supplied with cooling air by way of line 31. A labyrinth seal (25, Fig. 5) surrounds the bottom of the shaft 24.

Abstract: 1,232,199. Polyacyloxamidrazones. GLANZSTOFF A.G. 9 July, 1969 [10 July, 1968], No. 34508/69. Addition to 1,139,279. Heading C3R. Polyacyloxamidrazones are obtained by reacting N,N<SP>1</SP> - dimethyloxalic acid bisamidrazone of formula in a single phase solvent or solvent mixture or a two-phase solvent mixture, with a dicarboxylic acid halide of formula where R is a direct bond or an aliphatic, cycloaliphatic, araliphatic or aromatic radical and X is chlorine or bromine, at 20‹ to 40‹ C. in the presence of an acid acceptor. In examples N,N<SP>1</SP>- dimethyloxalic acid bisamidrazone is reacted with terephthaloyl chloride. The polymers can be converted to poly-bis-(1,2,4-triazoles) by heating.

Abstract: 1,232,544. Bobbin holders. LEESONA CORP. 8 April, 1969 [26 April, l968], No. 17854/69. Heading D1J. The reserve bobbin 12 is dropped down through the left-hand tube 14 onto a magnet 40 surrounded by a dished seat 16, the bobbin 12 being on a core 18 having a head 92 attracted by the magnet 40. When the bobbin 12 is empty an arm 96 is driven by a shaft 26 to a setting in which a finger 106 on the tube 14 rides over a depending lobe 108 in a manner rocking the tube 14 and the core 18 away from the dished seat 16 and so permit the core 18 to drop out of the tube 14.  To facilitate pneumatic retrieval of the yarn end 20 from the hollow core 18, each seat 16 has air passages 114 opening into gaps between the poles of the magnet 40 within the seat.
