Filed: 1954-11-04
Abstract: 775,593. Measuring temperature electrically. BRISTOL CO. Nov. 4, 1954, No. 31966/54. Class 40 (1). An arrangement for measuring temperatures at a plurality of points comprises a set of thermocouples with their hot junctions at the respective points and each having its own cold junction or junctions maintained at the same temperature as a temperature sensitive impedance forming part of the measuring network with which the thermocouples are associated. The impedance and cold junctions in the embodiment are housed in a heat-conducting structure (Figs. 3 and 4), comprises a hollow cylindrical aluminium spider 40, formed by casting, extrusion, machining from the solid, crimping of a tube or from laminations carried on a central tube, in the axial slots 42 of which are mounted the cold junctions. The spider is positioned in metal shell 60 by plates 61 of insulating material with an insulating collar 63 abutting one of its ends. Into the hollow of the spider is removably fitted a shouldered insulating block 44 bearing a metal spool 41 wound with the temperature-sensitive impedance 18a, heat being carried to the spider via spring washer 43. An earth connection 67 is made through a similar washer 66 and the assembly completed by washers 68 and potting compounds 69. Each cold junction assembly may be formed of a number of conductors of different materials likely to be used for the hot junctions and Cu, of which the terminal conductors of the measuring network are made, welded, soldered or clamped together. In the self-balancing network shown in Fig. 2, the terminal conductors 21, 22 are selectively connected to the respective thermocouples T1, T2, T3 through double-pole dial switch 25 the studs of which are connected through Cu leads C to Cu conductors of the respective cold junctions. In this case in which iron-constantan hot junctions are used each cold junction comprises two Cu conductors and an iron or constantan conductor respectively the second pair of Cu conductors remaining idle. Modification for use of copper constantan couples is effected by connection of the junction elements to corresponding metal conductors of the cold junction assemblies and replacement of the removable spool assembly by one carrying a suitable temperature-sensitive resistor. Specification 602,460 and U.S.A. Specification 1,169,611 are referred to.

Title: Improvements in or relating to record card controlled statistical machines
Filed: 1930-10-28
Abstract: 365,220. Statistical machines. STANLEY, W. C., 249, Thornton Road, Croydon. Oct. 28, 1930, No. 32397. [Class 106(1).] Total - taking.-In a recordcard-controlled statistical machine having adding and printing elements, each of which is normally held by a nought shutter or stop which is released to allow the elements to be set differentially by the card-reading, this nought shutter is released by power means independently of the card-reading devices so that the analysing mechanism has only to do the work of lifting the setting stops. The shutter is similarly held released during the whole of a total-taking cycle. The heel 6 of each adding and printing sector 3, in a machine of the kind described in Specification 26896/13, [Class 106 (i), Calculating &c.], is normally held by a lug 5 on a nought shutter 4 which is bent at 7 to receive the ribs 8 of the associated column of pins 2 which are raised by the card-reading pins through rods 1. As analysing commences the shutters 4 are rocked free of the pins 2 by the means described below and any pin 2 thereafter raised to arrest differentially a sector 3 prevents the shutter 4 returning by reason of its rib 8. In this way the pins 2 do no work in rocking the shutters. Each shutter 4, Fig. 5, is biased by a spring 9 and passes through a comb 12. At each analysing operation the main adding shaft 22, through linkage 21, 24, 23, rocks the back total shaft 19 so that the cam 18 on the latter slides the nought release comb 12 to the left, Fig. 5, rocking all lugs 5 free from the heels 6. At restoration of comb 12 to the right, the spaces in it allow any raised pins 2 to maintain their shutters 4 rocked. At total-taking the front total shaft 28 moves a link 27, having a pin-and-slot connection 29, 30 with link 23 so that cam 18 maintains comb 12 to the left and all shutters 4 rocked throughout the total-taking. Shaft 28 is rocked as described in Specification 26896/13.

Title: A process for the production of cyclohexanone
Inventor: POEHLER GUENTER
IPC: C07C45/00
Filed: 1959-09-24
Abstract: Cyclohexanone is produced from aniline or nitrobenzene by a process wherein the initial material is led with an equal or greater amount of water or steam and with an excess of hydrogen at a temperature of 150 DEG -300 DEG C. over a hydrogenation catalyst, the reaction mixture formed is cooled, freed from the gaseous constituents and reacted in a pressure vessel in the liquid state at a temperature of 250 DEG -350 DEG C. in the presence of a dehydrogenation catalyst under the vapour pressure of the water containing reaction mixture set up by the prevailing temperature, the hydrogen and ammonia formed during the reaction being removed continuously from the pressure vessel.  The hydrogenation is preferably carried out at 170 DEG -225 DEG C. using metallic copper, zinc, nickel or iron or their oxides or sulphides as catalyst at normal or elevated pressure.  The dehydrogenation may be carried out using metallic copper, nickel or zinc or their oxides as catalyst and at a pressure of 40-60 atmospheres.  The dehydrogenation may be carried out in two or more stages using the same or increased temperatures.  In an example the dehydrogenation is carried out, using finely divided copper, in three reactors connected in series where the liquid catalyst mixture is kept in motion by passing steam up through the mixture and the gases evolved are carefully decompressed so there is no appreciable vapourisation of the liquid portions.
