Title: Improved process for protecting magnesium and its alloys against corrosion
IPC: C23C22/57
Filed: 1931-05-19
Abstract: To protect magnesium or magnesium alloys against corrosion the metal is immersed in or rubbed or sprayed with a solution of selenious acid or a solution of a soluble selenite containing one or both of (a) selenious acid and (b) an acid or salt which corrodes the metal, e.g. sodium chloride.  Examples of solutions containing a soluble selenite are: a solution of sodium selenite and phosphoric acid; a solution of sodium selenite, selenious acid, and sodium chloride.  A solution containing sodium selenite and hydrochloric acid is referred to in the Provisional Specification.  It is stated that a coating containing selenium in the elemental or combined form is deposited on the metal.  The protective action may be improved by heating the coated metal to 170-225 DEG  C.  The coating forms a good basis for paints.

Title: Control systems for generators
IPC: G05B19/4093
Filed: 1970-03-26
Abstract: 1307017 Controlling movement LICENTIA PATENT - VERWALTUNGS GmbH 26 March 1970 [29 March 1969] 14889/70 Heading G4H In a system for controlling an output quantity such as the movement of a spot on a cathode-ray tube in accordance with digital data, the full digital range is divided into a plurality of subranges each having the same group of digital signals and a computer calculates the required output quantity by extrapolation, to distinguish between the various sub-ranges, thus reconstructing the full range of the input. The signal generating unit comprises a ball bearing 2 upon which two friction wheels 4 and 5 bear. The friction wheels drive coded discs 6X and 6Y associated with contact elements CX and CY. Depression of switch 7 activates the unit. Movement along the X and Y axes is encoded in Gray code by units 6X, CX and 6Y, CY respectively. The coding discs are characterized by being divided into a number of zones each zone being identical, the code values changing regularly throughout each zone. Thus the digital information derived from the coding disc merely indicates the position of the signal generating unit within a zone and not in which zone the unit lies. The position indicated by the coding discs 6X or 6Y and the pick-ups CX or CY is transferred on receipt of a transfer pulse from unit TG, to a shift register 14. In the interval between transfer pulses this information is transferred in serial form from the shift register 14 to a computer R. The computer determines which zone the signal generating unit lies in by calculating an extrapolated position on the basis of data referring to previously recorded points, and calculating the velocity and acceleration of the signal generating unit. The observed position is compared with the extrapolated position in order to determine the particular zone in which the signal generator lies. The full digital representation of the position of the signal generating unit is stored in the computer and fed via a shift register to a digital to analogue converter and thence to the cathode-ray tube display.

Abstract: 545,416. Lubricants. NATIONAL OIL PRODUCTS CO. Oct. 9, 1940, No. 15070. Convention date, Sept. 30, 1939. [Class 91] [Also in Group IV] Ethers are obtained by condensing a derivative of a fatty alcohol containing 6-22 carbon atoms with a derivative of methallylalcohol, one of the said derivatives being an alkali metal derivative of the alcohol and the other a halide arylsulphonic ester or sulphuric acid ester of the other alcohol. The ethers which may be converted into surface active agents by sulphonation may be used as textile lubricants. They are polymerized by heat, forming plastics and they may be added to lubricants and solvents. The sulphonated ethers are melting, detergent and foaming agents. In examples; methallyl chloride is condensed with the sodium compound lauryl alcohol and the ether sulphonated. The product is worked up by adding acetone, after extracting the sulphonated ether with ethyl ether, partly evaporating to cause separation of an oily substance and extracting the latter with heptane ; (2) the sodium compound of methallylalcohol is condensed with cetyl bromide, octyl chloride and the chlorides of rice bran alcohols (oleyl and linoleylchlorides) and the resulting ethers sulphonated. Naphthenyl alcohol, octadecanol and 2-ethylhexane-2-ol are specified fatty alcohols which may be used as starting material. Acetic anhydride and ethylenedichloride may be used in the sulphonation process as solvents. The Specification as open to inspection under Sect. 91 comprises also the production of ethers having the formula R<SP>1</SP>R<SP>2</SP>C= CR, (CH 2 )n OR, wherein R 1  and R 2  are hydrogen or alkyl groups with not more than 4 carbon atoms, R, is an alkyl group with not more than 6 carbon atoms, R 4  is the fatty alcohol residue and n is an integer from 1-3.
