Abstract: 1,118,348. Measuring limit of visibility. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI (ACEC). Oct.14, 1965 [Oct. 14, 1964; April 7, 1965], No.43552/65. Heading G1A. An arrangement for measuring the limit of visibility in fog comprises a series of signalling elements i.e. lights, or retractable viewable objects, an observation system which projects a signalling element or elements on to a screen, and a control device whereby certain of the elements may be made observable and a lens of the observation system adjusted to display at least one of them. The elements of the arrangement may be manually switched, or may be designed automatically to follow changes of limit, and a system may comprise a number of such arrangements. In a monitoring system three lights are monitored on a screen, the farthest producing the merest dot, and adjacent nearer or farther lights of the series are switched on according to whether the centre light has disappeared or the dot has expanded respectively. Stepping of a switch selects a circuit from a group of similar circuits each of which corresponds to a limit of visibility the circuits including motors and limit switches to adjust the focal length of the optical system and the aim of the camera. In a further system a single light is arranged to fall on a photo-cell for comparison with the ambient detected by a second cell, the ambient signal being adjusted before comparison by a function generator which takes account of a pilots physiological factors and secondary influences such as snow covered or moist ground or the colour of the grass. The system may include an infrared filter, and the visibility is indicated by a pilot light in the particular circuit of which the lights are illuminated and displayed. An automatic stepping system using a rotary change over switch in conjunction with the ambient comparison system above is described and is relay controlled according to the polarity of the output of the comparison device. The relays are released and the test repeated by a continuously rotating commutator, means being provided for maintaining the pilot light visibility indication until such time as the visibility alters. Electronic switching circuits may alternatively be used. In a further arrangement, the observing means comprises a television transmitting tube and an analysis is made of the video signal, a comparison with the ambient again being made. Two successive lights may be similarly monitored and their difference intensity used to control which lights of the series are illuminated and thus to follow the limit of visibility.

Title: Fluidised bed operation
IPC: B01J8/32
Filed: 1964-10-30
Abstract: In fluidized catalytic cracking of hydrocarbon feeds, there are added to the fluidized bed free motion contactors which have density \sB20 weight per cent of the apparent density of the fluidized bed, and are at least twice as large as the largest size of catalyst particles. In the example, a silica-alumina catalyst which is about 25% Al2O3 is fluidized by the cracked products of a hydrocarbon feed boiling in the range 450 DEG  to 1000 DEG  F., in a cracker operating at 900 DEG to 960 DEG  F.  20 to 40 bulk vol. per cent of contactors made of expanded alumina shaped like sections of 3-inch diameter pipe are added to the bed.  There is reference to hydroforming, hydrodesulphurization and hydrocracking.  In a hydrocracking operation, the contactors may be made of hydrogenation catalyst while the bed itself is cracking catalyst.ALSO:In the direct reduction of iron ore in a fluidized bed of iron ore solids, there may be added to the bed free motion contactors which have density in the range of \sB 20 weight % of the apparent density of the fluidized solids and are at least twice as large as the largest size iron ore particles. Contactors referred to in the Examples are made of carbon in the form of spheres, extrudates, or Raschig rings.ALSO:A fluidized bed operation is improved by adding to the bed free motion contactors which have a size of one to two hundred times p  the diameter of the largest particles in the bed and a density within the range of \sB 20 weight % of the apparent density of the fluidized particles, the contactors being added in an amount sufficient substantially to reduce the pressure fluctuation across the bed.  The contactors may be added in amount 5 to 90 bulk volume % based on fluidized volume of solids + contactors.  The contactors may be made of coke, metals, for example aluminium, wood, foamed refractories such as aluminium oxide, or plastics material and may be catalytically active.  Examples relate to reduction of iron oxide ores to metallic iron using as contactors (1), spherical carbon particles; (2), carbon extrudates; (3), (4), carbon raschig rings; and (5), cracking a hydrocarbon feed using a SiO2-Al2O3 catalyst and alumina contactors in the shape of pipe-sections.

Abstract: 1400865 Making semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Sept 1972 [2 Oct 1971] 45101/72 Heading H1K In manufacture of semi-conductor devices, a semi-conductor body is masked with an apertured layer which comprises silicon nitride and is resistant to oxidation and to an etchant specific for the semi-conductor. Recesses are etched in the body through the apertured masking layer which is undercut. The overhanging edges of the masking layer are then removed, as by etching, and oxidation of the recessed semi-conductor surface is carried out to build up oxide in a LOCOS process. If a silicon nitride masking layer of adequate thickness is used it need not be masked during etching of the edges. A triple layer oxidenitride-oxide maks may have its component layers selectively etched at the edges. Ultrasonic removal of the edges is less desirable. In the preferred embodiment, oxide-nitrideoxide is used to mask a silicon body during the production of pairs of parallelled IGFETs. Within each pair there are a common source region and source electrode, a common drain region and drain electrode, but separate gate electrodes. The gate insulation is formed by material from the lower oxide layer of the mask.

[Also in Division B3] In a method of cutting a mineral insulated cable followed by jointing or terminating, the cut end is exposed to an inert gas under pressure which impregnates the end so that during jointing or terminating the cut end is protected from the atmosphere by the escape from the insulation of the inert gas. The cable is drawn through a bore 6 in one of the sealing heads 2, 4, 5, through the tapering bore 12 (Fig. 2, not shown) of a shearing pin 7 and out through the bore 6 in the other sealing head. The nuts 5 are then tightened to press on metal thrust plates 4 in the chamber 1 so that the central bore 13 is sealed at both ends by rubber bungs 2. The chamber is then evacuated through an aperture 15 and the shearing pin rotated by turning a handle 14, so as to cut the cable, the cut ends then being exposed to an inert gas which is pumped into the bore 13 to a pressure above atmospheric. The cable ends may then be removed from the apparatus and either joined with other cables or terminated, the cut ends being protected from the atmosphere by the inert gas escaping from the insulation of the cable. In a modification of the method, the chamber 1 is filled with inert gas before insertion of the cable. Two cable ends may be joined in a sealed welding chamber, the chamber being evacuated before the welding process commences so as to remove the gas from the cable insulation. The above method is more especially concerned with the formation of a hot junction between the wires in a mineral insulated thermocouple cable.
