A resistor, Fig. 1, comprises a glass substrate 10 having a metal oxide film 12 which may be spiralled. Leads 14 having conducting discs 16 make contact with the film 12 through conducting bands 20 of silver frit. the resistor being hermetically sealed by a glass coating 22. In the manufacture, the substrate 10 with the leads 14 and discs 16 are rotated and the bands 20 are applied, bonding material of glass film 18 having been previously applied to the discs 16. Also, during the rotation, the coating 22 is applied in the form of molten particles by plasma jet means, the heat transferred from the glass causing fusion of the bands 20 to the substrate 10 and discs 16 and fusion of the films 18 to the substrate. In a modification (Fig. 2, not shown), the substrate 10 has a bore therethrough and the discs have central pins extending into the ends of the bore to provide a rigid structure. In another modification, Fig. 3, in which the diameter of the leads 42 is approximately equal to the diameter of the substrate 40, the leads have grooves 44 into which the glass coating 48 is applied.

Title: Removing nitric oxide from gas mixtures
Inventor: RITTINGER WILHELM
IPC: C10K1/10
Filed: 1963-10-17
Abstract: Nitric oxide is removed from gas mixtures containing carbon monoxide, carbon dioxide, hydrogen, nitrogen and saturated and unsaturated hydrocarbons, which are to be subjected to low temperature treatment, by a process comprising adding oxygen in slight excess over that required for oxidation of the nitric oxide according to the reaction 2NO + O2 --> 2NO2 and forming and separating nitrogen dioxide and any secondary oxidation products such as dinitrogen trioxide and dinitrogen tetroxide simultaneously with the removal of carbon dioxide by washing with an aqueous washing liquid under a pressure of 8-40 atmospheres in a scrubber.  The wash may be sodium or potassium hydroxide or sodium carbonate.  Oxygen is supplied either in the gas phase or in dissolved form in the wash liquid, which is preferably at room temperature.  Nitric oxide contents of 1 p.p.m. are thus reducible to 0.01 p.p.m.

The members are held against relative axial movement but may be rotated one relative to the other to alter the dimensions of the air gap and thereby alter the inductance of the choke. Fig. 2 shows a pair of members having two-start threads, the inner member bearing a winding in which the current through adjacent turns flows in opposite directions. Angular adjustment may be by means of a pinion 12 and worm drive. A thread with a multiple of two starts may also be used.

Filed: 1960-11-29
Abstract: Viscose is produced by mixing cellulose crystallite aggregates having an average level-off D.P. of 125 to 375 with carbon disulphide and mixing this mixture with an aqueous caustic soda solution. Preferably at least 85% of the material has a D.P. of 50 to 550, more preferably at least 90% of the material should have a D.P. of 75 to 500, and still more preferably at least 95% of the material should have a D.P. of 75 to 450.  The average level-off D.P. is preferably 200 to 300.  The crystallites may have a particle size of below 1 micron to 250 microns, usually from 2 to 40, 60 or 100 microns. Preferably at least 95% of them should have a particle size of less than 10 microns, particularly 1 to 2 microns. The viscose may contain from 5 to over 18% of aggregates, which have been reacted with carbon bisulphide.  The proportion of carbon bisulphide may be 20 to 75%, preferably 30 to 50%, more preferably 25 to 40% of the weight of the aggregates. The proportion of caustic soda used may be 4 or 5 to 12% by weight, based on the viscose.  The mixing temperature is preferably below 20 DEG C.  The carbon bisulphide may be in the liquid or in the gaseous phase.  It may be in the form of an aqueous emulsion preferably containing 20 to 75% by weight of carbon bisulphide. Each of the cellulose crystallite aggregates may be made up of a number of chains of substantially uniform length, the constituent chains in each aggregate being separate from and free of those in neighbouring aggregates, and each chain being characterized by having a potential aldehyde group in the 1 position of an end anhydroglucose unit thereof. This potential aldehyde group may have been reduced to a hydroxyl group or oxidized to a carboxyl group to render the cellulose of the viscose resistant to degradation by caustic soda at room temperature.  Specification 970,111 is referred to.

Abstract: 1,018,875. Aircraft landing places. AIR LOGISTICS CORPORATION. Nov. 5, 1962, No. 41792/62. Heading B7G. A runway for decelerating a wheeled aircraft comprises a base, a depressible portion over the base, and a body of liquid between the base and the portion so that as an aircraft rolls over the runway it progressively depresses the depressible portion and the liquid absorbs the kinetic energy of the aircraft. As described a bag 20, made, for example, of PVC or polyethylene, filled with liquid or liquid and gas is contained in an elongate basin 3 (Fig. 2) having a hard base 11 and covered by a flexible cover 12 comprising for example nylon tyre cord or canvas impregnated with an elastomer such as neoprene, and preferably having longitudinal strips 25 of synthetic plastic or glass-reinforced synthetic plastic so that it is more resilient in the transverse sense.

Tension springs such as 36 may be used for other edges of the cover. The runway may be disposed either at the end of,'or to the side of a normal hard runway and may be coloured to distinguish it therefrom. The depth of the basin preferably increases towards its far end to provide increasing retardation, and the sides slope gently to facilitate the removal of an aircraft from the runway.

[Also in Division F4] A method of treating cut tobacco for drying and improving its filling power comprises treating the tobacco with hot drying air which is also the conveying medium, the hot air containing not less than 1 part, by weight, of moisture to 10 parts of dry air. Cut tobacco to be dried is carried through drying chambers 6 of the type described in Specification 875,684 by a current of hot air containing a high proportion viz. not less than 10% of water vapour, the air being recirculated continuously in a substantially closed system. The water vapour content of the air is regulated by bleeding off at 14 a small amount of air and admitting make-up air through 16 and additional steam or water vapour at 21. Droplets of moisture in the air are removed by baffles-a chamber 19 and a temperature sensing element 21 beyond the chamber 19 is connected to a damper 17 in the duct 16 to control automatically the quantity of air introduced into the system. The temperature of the hot drying and carrying air is sensed by an element 26 after leaving a separator 7 for further heating, if necessary, from whence the tobacco passes to a cooler 10, the element being connected to a controller 26a which controls a valve 22 to direct proportions of air from the chamber 19 either to a heater 23 or by-pass duct 24.
