Title: Improvements in or relating to methods of and apparatus for measuring the intensity of x-ray radiation
IPC: G01T1/18
Filed: 1953-10-05
Abstract: 744,397. Measuring X - ray intensity. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 5, 1953 [Oct. 8, 1952], No. 27252/53. Class 40 (3). In apparatus for measuring X-ray intensity for example in strip metal gauging periodic surges of X-rays are directed first to the specimen and then to a detector which produces a train of pulses corresponding to each surge, the number of pulses depending on the intensity of the surge received. The successive trains of pulses are integrated to produce periodic pulses having an amplitude proportional to the number of pulses in the train and the amplitude of these periodic pulses is then used to indicate the intensity of X-ray emission. As shown, X-ray surges are produced by alternating current circulation of an X-ray tube 10. The surge of X-rays thus produced passes to a specimen 23 under test and thence to a proportional counter 11, which produces a train of pulses the number of each of which depends on the intensity of the transmitted radiation. The pulses are developed across a resistor 27 integrated by a condenser 28 and the periodic pulses thus produced, whose amplitude varies with the number of component pulses in each, are fed through a transformer and amplified in three cascaded stages 13, 14, 15, fed through a rectifier 34 and an averaging circuit 35 and recorded by conventional means 18. A parallel " T " network 16 is provided for degenerative feed-back of all frequencies other than that of the pulse repetition frequency supplied to the amplifier. An alternating current meter or recorder 36 may be connected direct to the amplifier output.

Title: Improvements in or relating to rust preventing compositions and process
IPC: C10L1/19
Filed: 1951-11-22
Abstract: Esters of the formula <FORM:0712431/IV (b)/1> where X is a straight-chain alkyl radicle containing at least 12 carbon atoms, one Y is an alkyl radicle containing not more than 3 carbon atoms in a straight chain, and the other Y is hydrogen, are employed in corrosion-preventive compositions (see Group III).  In the preparation of such esters, olefins are reacted with maleic anhydride to form alkenyl succinic acid anhydrides, which are then hydrogenated to convert them to the corresponding alkyl succinic acid anhydrides, which are esterified with stoichiometric quantities of the desired alcohols.  Esters mentioned are the mono-(methyl, ethyl) n-propyl, iso-propyl, sec.-butyl and tert.-butyl, esters of n-octadecyl succinic acid and the monopropyl ester of n-tetradecyl succinic acid. In comparative tests the mono-n-butyl and mono-n-amyl esters of n-octadecyl succinic acid are also mentioned.  U.S.A. Specifications 2,055,456 and 2,411,215 are referred to.ALSO:Corrosion of ferrous metal surfaces is prevented by applying to the surfaces a solution in an organic medium of an ester of the formula <PICT:0712431/III/1> in which X is a straight chain alkyl radicle, containing at least 12 carbon atoms, one Y is an alkyl radicle containing not more than 3 carbon atoms in a straight chain, and the other Y is hydrocarbon. The organic medium may be a lubricating oil, for example mineral lubricating oil, polyoxyalkylene glycols, polyethylene, and esters formed by reacting branched chain aliphatic alcohols with straight chain dibasic acids such as sebasic and adipic acids, particularly di-(2-ethylhexyl) sebacate. Other organic media are carbon tetrachloride, benzene, kerosene, naphtha, and mixtures of alcohols and benzene.  The lubricating oil solutions may be employed as lubricants, slushing oils, cutting oils and coolants for metal fabricating.  The esters may also be added to transformer oils, hydraulic fluids, torque converter fluids, heat transfer fluids, anti-freeze fluids, flushing oils, gasoline, fuel oils and other liquid petroleum hydrocarbons.  Esters mentioned are the mono-(methyl, ethyl, n-propyl, iso-propyl, sec-butyl, and tert.-butyl) esters of n-octadecyl succinic acid and the monopropyl ester of n-tetradecyl succinic acid.  The ester solutions may contain additional ingredients such as oxidation inhibitors, particularly di-tert.-butyl-p-cresol, phenyl-alpha-naphthylamine and phenothiazine.  Oil solutions of the esters may contain such additions as pour point depressants and extreme pressure additives. For comparison purposes, mineral oil compositions containing n or iso-octadecyl succinic acid, iso-octadecenyl succinic acid, or the mono-n-butyl or mono-n-amyl ester of n-octadecyl succinic acid, with or without di-tert.-butyl-p-cresol, are described.

Convention date, Oct. 2, 1930. [Class 23.] Particles are separated from a fluid medium which is centrifuged by means of rotary blades in a smooth passage having a sectional outline curving outwardly in an axial plane from the axis of rotation. The blades 1 are secured edgewise to the face of the member 6 mounted on the shaft 7 and located in a casing 8 so arranged that when the member is rotated air is drawn in axially and passed out between the blades 1 to a convolute passage 10 and a tangential discharge tube. To prevent eddy currents, a curved annular extension 8a of the passage wall passes between the blades 1 and the passage 10. The longitudinal edges of the blades are arc-shaped and the advancing faces are concavely curved ; the discharge ends of the blades have channels 3 to receive the particles and deliver them to the casing 12 and the hopper 13. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a separator having blades 1, Fig. 1 (Cancelled), of sheet metal curved to make passages 2. As the medium flows through the passages particles are deposited on the blades 1 and slide along to the channels 3. This subject-matter does not appear in the Specification as accepted.
