Title: Improvements in or relating to the stabilisation of hydrogen peroxide
IPC: C01B15/037
Filed: 1959-02-17
Abstract: Aqueous hydrogen peroxide solutions are stabilized by incorporation of a magnesium salt of an amino poly carboxylic acid having the general formula:  <FORM:0852102/III/1> where R is an aliphatic or aromatic radical containing one or more oxygen, sulphur or nitrogen atoms.  The substituent R may also contain one or more carboxyl groups, one or more of which, if salified, are salified with magnesium.  The magnesium salt may be added to the hydrogen peroxide solution e.g. solutions used in industrial bleaching baths, in proportions of preferably 0.1 to 5 gms./litre.  The use of di-magnesium ethylenediamine tetraacetate, sesqui - magnesium nitrilo - triacetate, sesqui - magnesium hydroxy ethylethylene diamine triacetate, the magnesium salt obtained by salifying 3, 4 or 5 carboxyl groups of diethylene-triamine pentaacetic acid with magnesium, magnesium anthranilic-N,N-diacetate, or mono-magnesium hydroxyethyliminodiacetate are referred to.

Title: Improvements in poppet valve gear for fluid pressure engines
IPC: F01L31/16
Filed: 1930-02-19
Abstract: 345,775. Lubricating engine valve tappets. CAPROTTI, A., 4, Via Mercadante, Milan, Italy. Feb. 19, 1930, No. 5582. Convention date, Feb. 28, 1929. [Class 12 (ii).] Single or multiple engines may be partly cut off by putting one or more valves out of action by means of angularly-movable tappets. The cam-operated lever u, Fig. 8, operates the valve stem f through a piston e and stem e<1> mounted in a rotatable guide g. The lever n acts upon a hardened piece e<2> bearing upon changeable shims mounted in the piston e which slides in a chamber q. The guide may be rotated to the dotted position by means of a lever H to put the valve out of action. In order to facilitate the use of the swinging tappets, the main valves are returned by fluid-pressure instead of springs. The fluid is cut off to bring the tappets into action. The oil in the cam box communicates with the chamber q and is kept at a higher position than the lowest position of the piston e. The piston and rod are provided with ports and a ball-valve, and the lower part of the chamber q acts as a pump to effect the lubrication of the piston and to prevent leakage along the stem e<1>. Specification 170.855, [Class 122 (ii), Steam-engine distributing and expansion valves &c.], is referred to.

Abstract: 1376080 Timing circuits for photographic shutters ASHAHI KOGAKU KOGYO K K 7 Feb 1972 [27 Feb 1971] 5640/72 Heading G2A A computing circuit for a camera with an electronically controlled shutter comprises light responsive means RV, arranged to provide a voltage proportional to the logarithm of the intensity of light from an object, and a voltage dividing circuit to which the voltage is applied consisting of two variable resistors RF, RASA and a constant current device Q 3  in series, and means for adjusting the two resistors linearly in accordance with aperture value and film speed value respectively. The input light voltage is applied via a potentiometer VR, which is adjusted so that the collector current of logarithmic expansion transistor Q 5  varies in proportion to the intensity of light from the object. An emitter follower transistor Q 2  acts as a constant voltage source whose voltage with the value of the intensity of light from the object. The collector current of transitor Q 3  is set by a bias circuit consisting of field effect transistor Q 4 , resistor R 1 , variable resistor R 8  and diode D 1 . The collector voltage VOUT of transistor Q 3  varies with the setting of RF, RASA and the output of the photosensitive device and is applied to the base of logarithmic expansion transistor Q 5 . The resulting collector current i 2  of transitor Q 5  charges timing capacitor C T  , the time taken to charge to a predetermined voltage determining the shutter exposure time. In a modification, transistors Q2 and Q 3  are replaced by field effect transistors with simplification of the biasing of transistor Q3.

Abstract: 1,126,474. Measuring fluid-flow. G.N. PUZANOV, B.B. NEKRASOV, M.P. RYABOKON and V. V. BANDJUK. Feb. 10, 1966, No. 5852/66. Heading G1R. In a variable pressure fluid-flow meter having a passage 1 increasing in diameter in the direction of flow and leading into a passage 3, containing at least one grid 2, of greater diameter than the exit end of passage 1, and leading to a converging nozzle outlet static pressure at the nozzle outlet is measured by an orifice 4 extending radially outward of the nozzle outlet and the total fluidpressure in the direction of flow in the outlet nozzle is measured by an orifice 5. In an alternative arrangement when a gas flow is close to the initial velocity the nozzle 5 is replaced by an . orifice 6 extending radially outwards from the enlarged cylindrical portion 3 downstream of the grids 2. Temperature sensitive devices 7 are provided. The liquid flow rate is determined by the pressure difference in the orifices 4, 5 or 4, 6 measured by a differential pressure gauge 8. When measuring gas flow rates a pressure gauge 9 measures the static pressure of orifice 4. The converging nozzle may be of cubic parabolic form.

Title: Method of transferring lapped sheets
IPC: B41F21/05
Filed: 1949-03-04
Abstract: 676,218. Feeding sheets. FEENY, C. J. (Miehle Printing Press & Manufacturing Co.). March 1, 1950 [March 4, 1949], No. 5947/49. Class 100 (i). Sheet carries.-Sheets A, B, and C are fed in overlapping relation to a movable registering guide 10 where they are registered individually before being transferred to an impression cylinder 15 by grippers 11 and 12 on an oscillating arm 17. During the withdrawal of the sheet A from the table 19, the second sheet B is registered by the guide 10, so that as soon as the sheet A has passed slightly beyond the guide 10 the grippers 11 and 12 move in a direction substantially perpendicular to the sheet supporting surface of the table 19 such that gripped pads 11 engage the sheet B without disturbing the registration. The gripper fingers 12 are then rocked counterclockwise by cams to grip the sheet B while the guides 10 are rocked downwardly, but are returned to their operative position to register the next sheet C while the sheet B is being withdrawn. After the transfer of the sheet B the grippers are receded from the path of the sheet B while being returned towards the table 19. Specification 378,248 is referred to.

Title: Improvements in vapour heating systems
IPC: F24D1/00
Filed: 1937-03-01
Abstract: 478,779. Heating vehicles. VAPOR CAR HEATING CO., Inc. March 1, 1937, No. 6102. Convention date, April 20, 1936. [Class 64 (ii)] Steam is supplied from a pipe A through regulating valve B, Fig. 3, and distributing valve C, Fig. 4, to a radiator D. Condensate is discharged through valve C, and pipe 32, to the casing of the regulating valve B. The valve member 6, Fig. 3, is actuated through links 14, 15 by a thermostatic capsule 12 subject to the condensate which is being discharged. If steam reaches the capsule 12. the valve 6 is closed. The distributing valve C comprises a rotary member 24 which, in the position shown allows steam to pass from pipe 17 through port 31 to pipe 36 and thence to the radiator D, while condensate returns through pipe 37 to port 33, pipe 32 and port 9 of valve B. Space 19 communicates through passage 40 with pipe 44 through which drainage is discharged. When the space heated reaches the desired temperature, thermostat E, acting through relay F moves valve 24 to connect chambers 18, 23 and therefore pipes 17, 32. The radiator system is cut off and closed, except to the drainage space 19. After the steam is condensed, the system is prevented from filling with air by the provision of a check valve H opening away from the valve C. The pipe 46 may lead to any discharge point, but is preferably connected to the return pipe 32, which is open to the atmosphere through the casing of the valve B. An additional check valve 47 is provided. The system avoids the delay incurred when air has to be expelled from the radiator system after a reopening of valve C.

The vegetable oil may be corn, sunflower, soybean or cottonseed oil which may be hydrogenated or winterized. The egg yolk ingredient may be liquid, frozen or rehydrated dried egg yolks or whole eggs with or without liquid or frozen egg whites. The acid may be acetic and/or citric acid, e.g. in the form of vinegar or lemon or lime juice. The product may also comprise salt, sugar such as sucrose, dextrose, corn syrup, invert syrup, maltose or honey, mustard flour, paprika, monosodium glutamate, ethylene-diamine-tetra-acetic acid. The process may comprise feeding an oil phase, an egg yolk phase and in the case of salad dressing a cooked starch pre-mix by separate conduits to a single emulsification chamber under an atmosphere of an inert gas.
