Title: Resistance thermometers
IPC: H01C7/22
Filed: 1975-05-15
Abstract: 1474731 Thick film resistance thermometers ROSEMOUNT ENG CO Ltd 15 May 1975 [25 March 1974] 13116/74 Heading H1K A thick-film resistance thermometer comprises an electrically insulating cylindrical former 10, Fig. 1, of e.g. alumina, having on its external cylindrical surface a printed or deposited conducting film 11 in a predetermined pattern covering less than the entire external cylindrical surface of the former. The film is printed on the former using an ink containing glass and platinum particles and then the printed former is fired. As shown, the film 11 comprising a series of meanders 20 is provided with terminal pads 21, 22, each pad being connected at a respective end of the former to a respective end cap 12. By using a laser, spark erosion technique or air abrasive technique, a required number of connecting links 24 can be broken to trim the resistance of the thermometer, whereas fine trimming is achieved by cutting an electrically conductive region 25, two different shapes of which are shown in Figs. 5a-5c. Terminal pads may be arranged on the same end of the former, Figs. 3, 4 (not shown), in which case lead wires 30 are fixed, by cementing or glassing, in holes in one end of the former and jumper wires (32) are bonded between the respective lead wires and the respective terminal pads. The lead wires may also be connected to the ends of the conducting film by using two hollow or solid rivets of a soft or precious metal, each inserted in a corresponding hole in the former. A glazed protective insulating coating 14 is provided. The end caps 12 and the lead wires 33 may be of nickel, nickel alloy or gold.

Title: A method of desulphurizing metals
IPC: C21C1/02
Filed: 1947-05-19
Abstract: For desulphurizing metals, particularly iron, steel, copper, or aluminium, there is added to a molten body of the metal a mixture consisting of a desulphurizing agent such as carbonate of soda, a reducing agent such as calcium carbide, and an oxide or hydroxide of an alkali metal such as caustic soda.  As an example, to a molten body of cast iron was added one per cent by weight of a mixture consisting of 38 to 39 per cent carbonate of soda, 38 to 39 per cent calcium carbide, and 22 to 24 per cent caustic soda. The mixture was at room temperature, and within one minute the sulphur content was reduced from .06 to .018 per cent.

Title: Improvements relating to catalytic processes
IPC: C10G35/14
Filed: 1942-09-28
Abstract: <PICT:0582414/III/1> In a catalytic process, particularly for the treatment of hydrocarbons, wherein a finely divided catalyst is circulated successively through reaction and regeneration zones in each of which it constitutes a relatively dense fluidized phase, a portion of the regenerated catalyst is cooled and returned to the regeneration zone to control and regeneration temperature.  The Fig. shows the regenerator 56 mounted above the reactor 10 so that regenerated catalyst flows into the reactor through standpipe 12. The reactants are introduced by pipe 16.  The reaction products leave by pipe 36 and pass through a cyclone separator 38 in which suspended catalyst is collected and returned to the reactor. Spent catalyst is withdrawn from the reactor by standpipe 32, mixed with oxidising gas at 52, and passed by line 54 to the regenerator.  A portion of regenerated catalyst is withdrawn by line 72, passed through cooler 76, and returned to line 54. Catalyst suspended in the gas leaving the regenerator is intercepted by a cyclone separator 88 followed by an electric precipitator 96.  The dust collected in the latter is mixed with coarser particles withdrawn from the regenerator through line 104 and returned to the reactor.  A supply of make-up catalyst is maintained in fluidized state under pressure in hopper 114 and supplied through line 131 to the circulation system as required.

In a weighing scale of the type used for check weighing a series of articles of the same weight in which the weigh pan has a series of off centre receptacles which successively support the articles being weighed, vibrations of the beam, due to external shocks and shocks caused by loading and unloading of the receptacles, are minimised by arranging a series of springs and vibration dampers in such a manner that a turning movement applied to the scale support about either of the main axes of the central horizontal ellipse of inertia of the complete scale assembly turns said scale about that axis, thus ensuring that the centre of gravity of the scale remains stationary, the ratios of the moments of elasticity of the springs about these two main axes being equal to the ratio of the moments of damping of the vibration dampers and the ratio of the moments of inertia of the scale assembly about the same axes; by arranging the receptacles so that the centre of gravity of the articles ca<SP>1</SP>, ca<SP>2</SP> will lie in an ellipse (known as the ellipse of position) which is similar to the central horizontal ellipse of inertia of the scale and which intersects the vertical line passing through the centre of gravity of the scale; and by locating the centre of gravity of the counterweight Cc vertically above a horizontal straight line joining the centre of gravity of the unloaded pan CV to a point X on the ellipse of position disposed in symmetrical relation to the centre of gravity of the scale Cg, the ratio of distances Cc, X and CV being equal to the ratio of the weight of the unloaded pan and weight of the body being weighed.
