Title: Rotary vacuum pumps
IPC: F04C29/00
Filed: 1964-04-01
Abstract: 1,001,738. Rotary vacuum pumps. NEW YORK AIR BRAKE CO. April 1, 1964 [April 3, 1963], No. 13363/64. Heading F1F. A rotary-vacuum pump comprises three pumping units 17, 18, 19, Fig. 2, of gyrating piston type, mounted on a common shaft 21 with the end units 17, 19 identical with each other and approximately half the length of the intermediate units 18. Each unit comprises a circular cam 23, Fig. 1, eccentrically mounted on the shaft 21 and closely embraced by a strap 24 formed with a valve piston 25 guided in a circular guide pin 26 supported at its ends in a removable partition of the housing 11 and an end cover therefor. To provide a shoulder on which the partition rests the unit 18 is slightly less in diameter than the units 17, 19 and in compensation therefor slightly more than twice the length of each of these units. Air from the chamber 36 to be evacuated is sucked through a cored opening 27 and port 28 in the valve piston 25 into the pumping chamber 22 and discharged through a valved outlet 31. The pump units 17, 18, 19 may be connected in parallel to the chamber 36 or alternatively the pump units 17, 18 may be connected in parallel and discharge into the unit 19 so that the pump operates as a two-stage pump. The mass of the cam 23 of the unit 19 is identical with that of the unit 17 and half that of the unit 18 with the masses identically distributed except that the cam of the unit 18 is 180 degrees out of phase with respect to the units 17, 19 so that during operation of the pump, the pump is rotationally balanced. The three valve pistons may all be directed upwardly, as shown in Fig. 2, or alternatively the valve piston of the unit 18 may be directed downwardly. Each unit is surrounded by a water jacket 33 having an inlet 34 and an outlet 35. It is stated that much higher pumping speeds and greater volumetric displacements may be achieved.

Abstract: 514,452. p - Isopropyl - alpha - methyl - hydrocinnamic aldehyde. SOC. DES USINES CHIMIQUES RHONE-POULENC. May 6, 1938, No. 13602. Convention date, June 29, 1937. [Class 2 (iii)] p -Isopropyl-alpha-methyl-hydrocinnamic aldehyde is obtained by reducing the carboxyl group of the corresponding acid by general methods described in Houben "Die Methoden der Organisiler Chemisie," e.g., by heating at 300‹C. or higher, the vapour of the acid with formic acid over a catalyst such as titanium oxide, manganese oxide, aluminium oxide, zinc oxide or thorium oxide, or by heating a mixture of the calcium salt of the acid with calcium formate. The acid is prepared by condensing cuminyl chloride with the sodium derivative of ethyl methylmalonate, saponifying the product and heating the diacid formed to drive off carbon dioxide. Crude cuminyl chloride contains o-isopropyl benzyl chloride as an impurity, and the acid obtained may consequently contain some o - isopropyl - alpha, methyl-hydrocinnamic acid. The desired para acid may be purified by crystallization from the ortho acid in a small quantity of benzene. U.S.A. Specification 1,844,013 is referred to.

Title: Improvements in or relating to indicator mechanism for liquid dispensing apparatus
IPC: G06M1/30
Filed: 1959-04-22
Abstract: 863,096. Zeroizing-mechanism. SOC. D'ETUDES, D'INVENTIONS ET DE BREVETS S.E.I.B. April 22, 1959 [April 25, 1958], No. 13738/59. Class 106 (1). A liquid dispensing apparatus indicator comprises numeral drums zeroized by independently actuated levers co-operating with heart cams on the drums. As described, zeroizing is effected by depressing a button to rotate clockwise a shaft 6c by rack-and-pinion gearing, a cam-operated lever thereby disengaging a pinion in the drive to the lowest order numeral drum, pawls 6e freely mounted on the shaft 6c and normally urged counter-clockwise by springs 6f attached to stops 6g on the shaft 6 being moved clockwise to disengage arms 10f of levers 10 carrying transfer pinions 9 which levers are therefore successively, commencing with the units order, rendered free to rotate clockwise under the action of springs 10e to successively disengage the transfer pinions 9 and co-operate with heart cams 4 on the numeral drums 3 which are thus returned to zero. In counting, starting from the zero position, Fig. 2, rotation of the units drum 3 causes the lever 10 to be rocked counter-clockwise by co-operation of an arm 10a with the cam 4, this rotation continuing until the arm 10f is latched by the pawl 6e, the spring 6f biasing the pawl 6e to retain the lever 10 out of engagement with the cam 4 and ensuring firm engagement of the transfer pinion 9 as shown in Fig. 3. During subsequent actuation of the indicator, the tens, hundreds &c. zeroizing levers 10 are successively set. In a modification, Fig. 8, the pawls 6e are fixed and the levers 10 are mounted by a lost-motion connection on a shaft 10c which carries projections 10m cooperating with stops 10p on the levers 10, anticlockwise rotation of the shaft 10c causing the levers to be unlatched from the pawls 6e to effect zeroizing.

Abstract: 1286588 X-ray analysis COMMISSARIAT A L'ENERGIE ATOMIQUE 24 March 1970 [28 March 1969] 14301/70 Heading G1A In an apparatus for the chemical analysis of a specimen 5 monoenergetic X or γ-radiation from a source 1 is Compton scattered by a scattering material 2 and the absorbing power of the specimen as a function of the wavelengths generated in the scattering process is measured by a detector 4. The source 1 is either a radio-active source or a wide spectrum X-ray tube followed by an X-ray collimator or a crystal selecting the desired wavelength. The wavelength scanning is obtained by rotating either the detector/specimen arrangement or the source about the point of incidence of the beam on the scatterer 2, which itself is rotated at half this angular speed. A diaphragm 3 limits the beam after its passage through the specimen. The source is chosen so that at one point of the scanning, the specimen receives a wavelength equivalent to its K- absorption energy and its absorption at two energies, one on each side of the K-absorption edge, is measured. There may be more than one detector/specimen combination, and to provide a wide range of scattered wavelengths there may be a plurality of scatterers.
