Title: Improvements in the recovery of oxides of nitrogen
IPC: C01B21/20
Filed: 1929-01-16
Abstract: 324,220. Johnson, J. Y., (Bergfeld, L.). Jan. 16, 1929. Nitrogen oxides are absorbed from dilute gas mixtures, such as gases from the oxidation of ammonia or from the arc process by treatment with aqueous solutions of compounds of hexavalent chromium or of manganese of a higher valency than two, such as potassium chromate or bichromate, calcium permanganate, manganic sulphate or phosphate, &c. The solution may also contain salts such as sodium or potassium nitrate, or acids such as phophoric or arsenic acid. The absorption may be carried out at ordinary or raised temperature and at raised pressure. The solution or the solid substances obtained by evaporation yield concentrated oxides of nitrogen on heating, and the residues may be oxidized and dissolved for use again.

Abstract: 867,828. Measuring electrically. NATIONAL SMELTING CO. Ltd. Jan. 13, 1960 [Jan. 16, 1959], No. 1627/59. Class 40 (1). [Also in Group XXV] In a method of assessing the moisture content of a moving granular mass, the heat loss of a heated body within the mass is measured. In Fig. 1 a tube 1 is located, by supports 3, with its longitudinal axis parallel to the direction of flow of the moving granular material. The tube contains a mass 7 which is electrically heated and is provided with thermocouples 5 and 6 to measure respectively the temperature of mass 7 and the temperature of the granular material upstream of the heated mass. The heated mass consists of a metal block 8, Fig. 2, within which are mounted four electrical resistance heating elements 9 connected in series, asbestos fibre filling the space between the elements and insulating discs 10. The heated block is held in position in the tube by means of rod 16a attached to a plug 12 (see Group XXV). In an alternative arrangement two probes are used mounted side-by-side one containing the heated block and its thermocouple and the other containing the reference thermocouple. In either case the reference thermocouple may be mounted on a metal block similar to the heated block in order to equate the thermal capacities of the thermocouples.

Title: Improvements in vehicle suspension
IPC: B60G17/052
Filed: 1957-01-17
Abstract: 813,468. Pneumatic springs; road vehicle spring suspensions. FIRESTONE TIRE & RUBBER CO. Jan. 17, 1957 [Jan. 17. 1956], No. 1765/57. Classes 108(2) and 108(3) A pneumatic suspension system for a vehicle comprises an expansible air bellows 10 interposed between a frame member 15 and axle 19, compression springs 21, 27 extending longitudinally into the bellows from the axle 19 and frame member 15 respectively, damping means 25 interposed between the springs 21, 27 and movable longitudinally of the bellows in response to the resultant force of the springs, an air supply and exhaust control means 20 for the bellows above the frame member, and connections between the damping means and air control means to operate the latter in response to movement of the damping means. The two springs 21, 27 bear against opposite sides of a plate 24 to which a housing 28 is secured by bolts 29. Within the housing 28 are two expansible bellows 30A, 30B which are completely filled with a suitable liquid and connected by fine orifices in a nipple 32 threaded into a cross-head member 35. This member 35 extends through slots 36 in the housing 28 and is screwed to a pair of brackets 38 depending from the frame member 15. Flanges 40 on the brackets 38 co-operate with flanges 41 on extensions on the plate 24 to allow limited relative vertical movement between the plate 24 and brackets 38. The air control means 20 comprises an inlet 48<SP>1</SP> and outlet 49<SP>1</SP> controlled by a slidable disc valve 53 which is operatively connected to the housing 28 by an actuating rod 44. A spring 56 holds the disc valve 53 in place without interfering with its vertical movement. The inlet 48<SP>1</SP> is connected to an air pressure supply and the outlet 49<SP>1</SP> to atmosphere. Under normal load conditions the parts are in the positions seen in Figs. 2 and 3 with ports 48<SP>1</SP>, 49<SP>1</SP> closed, cross-head 35 midway in slots 36, and flanges 40 mid-way between the plate 24 and flanges 41. Increase or decrease of the load causes opening of the inlet 48<SP>1</SP> or outlet 49<SP>1</SP> respectively to admit or exhaust air to or from the bellows 10 to restore the frame to its initial position, with a time delay governed by the transfer of liquid from one of the two bellows 30A, 30B to the other through the orificed nipple 32. This time delay may be from 1 to 20 seconds, preferably 7 sedonds, and prevents operation of the valve 53 due e.g. to road irregularities. Small compression springs 31 within the bellows 30A, 30B assist in returning the cross-head 35 to its equilibrium position.

Title: Measuring the size of disperse elements
IPC: G01N15/14
Filed: 1973-01-15
Abstract: 1422442 Investigating immiscible liquids T PILHOFER 15 Jan 1973 [13 Jan 1972]  2052/73 Heading G1A In an apparatus for determining the size, speed &c. of fluid disperse elements (bubbles &c.) dispersed in and immiscible with a second fluid, the mixture is passed through a capillary tube 1 so that the disperse elements assume the shape of cylindrical plugs. Two spaced sets 2,3 of a radiation source and a photo-cell supply logic circuitry. Two signals are derived, one signal #t 1  being directly proportional to the plug length, the other signal #t 2  being directly proportional to the plug velocity. The signals are integrated and processed by an analogue computer to provide the required measurement of the disperse element. The apparatus may include means for deriving and counting pulses that indicate the leading and trailing edges of the sensor output pulses, the means being used to determine when each measuring cycle has been completed and to subsequently prepare the circuits for the next measurement. The flow-rate of homogeneous fluid may be measured with the apparatus by introducing an immiscible fluid in the form of disperse elements into the homogeneous fluid and where in the volume and cross-section of at least one of the disperse elements is known or has been determined. The description discloses formulae, suitable logic circuitry for processing the signals and methods of calibration of the apparatus. The calibration takes into account velocity dependent changes in the actual cross-section of the disperse element passing through the capillary tube and determines the maximum speed of the disperse element (before the disperse element distorts and breaks up).
