Title: Improvements in or relating to thermistors and methods of preparing thermistor materials
IPC: H01C7/04
Filed: 1957-11-15
Abstract: A thermistor composition based on cobalt oxide contains 88.3 to 99.95% cobalt, 0.07 to 1.2% of lithium and 0.18 to 10.5% of copper based on the total metal ions present.  The composition may be prepared by mixing the oxides in finely powdered state or preferably by mixing a heat decomposible compound yielding the required oxides, particularly carbonates.  The composition is finally mixed with an organic binder, shaped, for example by extrusion, and the mass obtained sintered at temperatures between 1050 and 1180 DEG C. According to Examples (1) a mixture of the oxides of cobalt, lithium and copper, obtained by calcination of the carbonates at 800 DEG C. for three hours was ground in alcohol, dried, sieved and mixed with a binder such as a solution of rubber in trichlorethylene, ceresin or polyvinyl alcohol.  The mixture was again screened and moulded by pressure of about two tons per square centimeter and sintered at 1075 DEG C.

Title: Process for stabilizing concentrated polyhydric alcohol solutions
Filed: 1958-11-06
Abstract: Concentrated aqueous solutions of one or more polyhydric alcohols, resulting from the hydrogenation of sugars obtained by hydrolysis of cellulosic material, are stabilised, at a temperature at which the concentration of one of the polyhydric alcohols in the solution is sufficient to cause its precipitation, by adding to the solution a polyhydric alcohol which is different from the polyhydric alcohol the precipitation of which it is desired to prevent.  If desired, the polyhydric alcohol may be added in the form of an aqueous solution the amount of water added being such that if added by itself it would not be sufficient to prevent the precipitation of the polyhydric alcohol(s) present in the initial solution.  In the examples (a) a solution containing sorbitol, xylitol and mannitol is steam distilled under vacuum to give a residual solution containing sorbitol and mannitol which are prevented from crystallising by the addition of a xylitol solution; and (b) xylitol is added to sorbitol solution to give a solution which can be stored without crystallisation of xylitol at a temperature above -12 DEG C.

Title: Improvements in or relating to impedance-inverting networks
IPC: H03H7/38
Filed: 1946-12-06
Abstract: 630,327. Impedance networks. SOC. INDUSTRIELLE DES PROCEDES LOTH. Dec. 6, 1946, No. 36174. Convention date, March 27, 1943. [Class 40 (viii)] [Also in Group XL (c)] In an impedance inverting network. constituted by a T or TT or bridge connection with a reactance -jz1 in the series branch or branches and reactance +jz2 in the shunt branch or branches, the reactances are controlled by two mechanical means of adjustment, one of which causes z1 and z2 to be varied simultaneously in such manner that at a given frequency z1=z2 is always fulfilled, whereas the other may vary z1 or z2 in which case z2 or z1 remains constant. The first control alters the transformation ratio while maintaining the network as an impedance inverter at the given frequency, whereas the second alters the frequency at which the network acts as an inverter. In the particular example shown in Fig. 4, the adjustable reactances are condensers C1 and C2 and the condenser in the shunt arm is divided into two portions C<1>2 and C<11>2 in parallel. C<11>2 is ganged with C1 to provide the first adjustment and C<1>2 is adjusted alone for the second adjustment. In one practical arrangement the condensers are mounted on shafts 1 and 2 linked by a differential 3. By holding the different casing stationary and rotating either shaft, the other is rotated an equal amount in the opposite direction and the first control step is effected. By holding one shaft stationary and allowing the differential casing to rotate the other step is effected. In an alternative construction using condensers adjusted by a linear motion the adjusting rods are linked by an adjustable telescopic coupling.

Abstract: 510,846. Lead-in conductors for discharge devices. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 15, 1938, No. 36581. Convention date, Dec. 17, 1937. [Class 39 (ii)] [Also in Group XL] The lead-in conductors to the electrodes of an electric discharge device are formed as concentrically arranged metal plates or films which are interrupted circumferentially so that they do not form completely closed rings. Fig. 1 shows a three electrode tube with an anode 4 supported on six separate conducting elements 8, Fig. 2, which are concentric with lead-in elements 9 carrying the grid 5. An indirectly-heated cathode 6 mounted on a conductor 10 has a heating- element 7 with supply leads 11, 12. The concentric conductors are fused within a pressed glass plate or base 1 on which the glass envelope 3 is fused at flanges 2. The lead-in conductors may be substantially in the form of concentric cylinders each with a single longitudinal slit. In a modification the conductors 14, Fig. 4, are flat and arranged iu the form of polygons or other geometrical figures. In a further modification the leads to the grid consist of a number of wires arranged on a circle. Some or all of these wires may be connected together outside the sealing-point, e.g., by a metal ring pushed over them or by annular segments, and may be continued into the interior of the vessel to form a grid electrode. A finely meshed grid can thus be built up by welding two or more wires to each sealed lead-in wire at a point adjacent to where the latter is sealed into the glass base of the vessel, these additional wires being forked and run parallel to the lead-in wires.
