Title: Improvements in or relating to heat measuring devices
IPC: G01K17/16
Filed: 1951-06-26
Abstract: 683,117. Electric indicating systems. TRUB, TAUBER & CO., AKT.-GES. June 26, 1951 [June 26, 1950; April 11, 1951], No. 15173/51. Class 40 (i). In a heat measuring device applicable to a heating system, thermojunctions 2, 4 (Fig. 1) in the supply and return paths are differentially connected in series with the resistance element of a wirewound potentiometer 5, and the moving coil 6 of a galvanometer is connected between one end of the potentiometer and its rotary slider 7, which is adjustable proportionately to the fluid flow in the system by a lever 9 and a disc cam 10 operated through a magnetic or mechanical coupling 11 by a float type quantity meter 12 responsive to the differential pressure across the system storage tank. The cam contour is such that the heat output of the system is proportional to the galvanometer deflection, and the pointer 23 carries a stop block 34 (Fig. 2) moving laterally between a curved support 19 and a spring-loaded clamping stirrup 20 pivoted about 21, which is lifted cyclically, e.g. once per minute, by the cam 22 driven by motor 14, to free the pointer for adjustment according to the instantaneous heat output. A cylindrical cam 16 rotated at the same speed as cam 22 cyclically oscillates a spring-loaded transmission lever 26 pivoted about an axis parallel to that of the galvanometer coil through the angle of maximum traverse of the pointer, and when the stop block 34 of the latter is clamped, a spring- loaded detector lever 17 having an extension 18 slidable in the clearance between support 19 and stirrup 20 is traversed to follow the transmission lever 26 until arrested by the clamped stop block of the pointer. The detector lever is connected through a hollow shaft 29 to a switch arm 28 having a latch 30, which consequently traverses a number of ratchet teeth on a switch wheel 32 proportional to the angle of deflection of the detector lever and to the instantaneous galvanometer deflection. With continued rotation of cam 16 the lever 26 is traversed back again to its starting point, and carries the lever 17 with it to rock the switcharm so that its latch rotates the switch wheel through a distance proportional to the instantaneous deflection of the clamped pointer, which rotation is transmitted to a numbering mechanism 33. The stop edge to the detector lever 18 is of curved configuration so as to compensate for any deviation from proportionality between the potentiometer contact arm turning angle and the galvanometer deflection due to the shunting effect of the potentiometer resistance upon the galvanometer. Compensation may also be by shaping the potentiometer resistance carrier according to a predetermined law.

Title: Process and device for the xanthation of alkali cellulose
IPC: D01F2/08
Filed: 1963-04-18
Abstract: An apparatus for the continuous xanthation of soda cellulose in the manufacture of viscose comprises a ring of cells or cavities 3 of equal volume located in a horizontal wheel 1 fixedly mounted on a rotatable shaft 2, illustrated in Figs. 1 and 2 (not shown). The wheel 1 is enclosed closed in a fixed casing with a very small clearance between the wheel and the casing to prevent as far as possible the flow of liquid or gas from one cell to another. The wheel is rotated in a stepwise or intermittent manner so that each cell in turn is subjected to the following cycle of operations.  The cell is brought to the position or station a where each cell is in turn filled with soda cellulose AC.  Each cell, after having been filled with soda cellulose is then brought to the position b, where it is evacuated, then to the position c, where an inert gas which does not support combustion (such as nitrogen) is introduced into the cell. Thereafter the cell is brought to the position d where carbon bisulphide is added to the soda cellulose in the cell.  The cell is then brought in turn to the position e, in which nothing is added to or removed from the cell, but the mixture of soda cellulose and carbon bisulphide is caused to remain in the cell for a predetermined period of time during which xanthation of the soda cellulose is initiated. Finally, in the cycle of operations the cell is brought to the position f where its contents are discharged into one end of a main reaction vessel 4 with the aid of nitrogen introduced under pressure into the top of the cell.  The reaction mixture is advanced slowly through the vessel 4 by means of the worm conveyer 5 and is continuously discharged from the other end of the vessel 4 into one end of a second vessel 6 which is provided with a mechanical stirrer 7.  The vessels 4 and 6 are provided with thermostatically controlled heating jackets 10 and 11 and with explosion pressure relief chimneys 8 and 9. Cooled soda lye is introduced into the vessel 6 through feed pipes 12 and water may be introduced into the outlet end of the vessel 6 if necessary.  Xanthation is completed in the vessel 6 and the xanthate dissolved in the dilute aqueous caustic soda solution to form viscose which is drawn off continuously from the outlet end of the vessel.  Each cell, after having been emptied at the position f is ready for a repetition of the cycle of operations. The reaction mixture may be caused to travel through the main reaction vessel and to be discharged therefrom into the second vessel by introducing into the main reaction vessel a volatile organic liquid such as benzene or light petroleum spirit which is miscible with carbon bisulphide and can subsequently be removed from the reaction products by fractional distillation or by decantation.  The interior of the main reaction vessel and the worm conveyer therein may be coated with polytetrafluoroethylene to prevent adhesion of the xanthate.

Title: Improvements in and relating to the production of 1:3-diols
Inventor: CRISP EDMUND THEODORE
IPC: C07C31/18
Filed: 1958-05-14
Abstract: A 1,3-diol is obtained by a process comprising reacting, at an elevated temperature, methanol with m-dioxane, or an alkyl derivative thereof, in the presence of an insoluble solid acid catalyst, displacing the equilibrium by distilling off the methanol/methylal azeotrope as quickly as it is formed and separating the 1,3-diol produced by fractional distillation. Suitable catalysts are, for example, tungstic acid, molybdic acid and, particularly, a cation-exchange resin containing acidic groups, especially those containing sulphonic acid groups.  The reaction temperature should not be so high as to result in the decomposition of the catalyst. The reaction may be carried out continuously or otherwise and may be represented by the following example <FORM:0824551/IV (b)/1>

Abstract: 918,209. Endless conveyers. POWLEY & SONS Ltd., R. March 28, 1960 [March 6, 1959], No. 15477/59. Class 78 (1). A conveyer 10 (Fig. 1) for bottles B in a washing machine comprises holders 13 from which a respective bottle B is released to a supporting cradle 19, 20 while the latter is being raised by the action of links 24, 26 and a cam-shaft 23. A bottle stop 29 which moves with the cradle 19, 20 has a further travel on the return (downward) movement of the latter and permits the bottle to pass on to a take-off table 30. The latter lifts the bottle B on to a conveyer 37 and has its movement derived from the cam-shaft 23. If a bottle B fails to leave its holder 13, it depresses a respective finger 38 (counterweighted at 41) to operate a micro-switch 42, thus stopping the conveyer or operating an alarm. Support arms weighted at 16 guide the bottles B while on the conveyer 10. The latter is driven by a ratchet mechanism (Fig. 4) which provides a dwell period in the washing and rinsing zones. A pawl 47 adapted to drivingly engage a ratchet 48 on the drive shaft 12 of the conveyer 10 is lifted out of engagement from the teeth on the ratchet 48 on every alternate stroke by the action of a part 52 of an arm 50 operated from a cam-shaft 54.

Title: Improvements in or relating to the provision on magnesium and magnesium base alloys of metallic coatings by electrodeposition
IPC: C25D5/42
Filed: 1948-06-10
Abstract: A process for the treatment of magnesium and magnesium-base alloys consists in immersing the metal in an aqueous solution of one or more compounds selected from the group consisting of the soluble salts of zinc, cadmium, and manganese which are decomposed by magnesium to produce a metallic deposit, treating the metal with an aqueous solution of chromic acid, then treating the metal with an aqueous solution containing a compound of mercury, and thereafter electro-depositing a film of another metal.  The metal may, for example, be treated with an aqueous solution of zinc chloride to form a black film of finely-divided zinc.  This film is partly washed off with water, then boiled in a solution of chromic acid to consolidate the zinc, after which it is treated with an aqueous solution containing a nitrate or cyanide of mercury whereby it is in a condition suitable for electroplating.

Title: Improvements in or relating to electric switchgear incorporating a mercury switch
IPC: H01H29/20
Filed: 1937-06-07
Abstract: 496,758. Arc-rupturing in switches ; mercury switches. BRITISH ELECTRIC TRANSFORMER CO., Ltd., and WEAVING, R. June 7, 1937, No. 15772. [Class 38 (v)] Electric switchgear comprises at least two contacts with which is associated a mercury switch so disposedthat actuation of the gear in a switch-closing direction completes through the mercury switch a shunt circuit across said contacts prior to the latter being brought together, and/or that actuation of the gear in a switch-opening direction causes the mercury switch to open after separation of said contacts, opening and closing of the mercury switches being effected solely under the influence of gravity. In Fig. 1, a pair of segments 3, 4 arranged on a drum-controller used for transformer-ratio changing on load, co-operate with pivoted fingers 1, 2, of which 1 carries the tilting mercury switch 5 having a contact 6 connected to finger 1 and a contact 7 connected to lead 8 and finger 2. Segment 3 is longer than segment 4, so that in making a change, the finger 1 is raised by segment 3 and tilts the switch 5 to make the shunt circuit before finger 2 engages segment 4, and the reverse process occurs in opening circuit. As applied to a knife-switch, Fig. 2 (not shown), the blade is adapted to interconnect two fixed contact clips and carries the mercury switch, which is connected across the clips so as to be tilted (and open the circuit) when the blade is moved out of contact with the clips. Fig. 3 shows a similar arrangement, but the switch 14 is carried on a pivoted bracket 18 having a cam surface 19 with which co-operates a pin 20 on the blade 10 so as to produce the necessary tilt. The Specification refers also to tilting with the aid of a solenoid.
