Patent GB-843093-A (GB)
Title: Improvements in or relating to controlling the temperature of liquids
IPC: A61L2/24
Filed: 1955-07-19
Abstract: <PICT:0843093/IV (c)/1> Apparatus for effecting temperature control of liquids at boiling point comprises means for collecting vapour bubbles formed on ebullition of the liquid, means utilising the bubbles to cause the heated liquid to flow over heat-responsive means and means actuated by the heat-responsive means for controlling the heat input to the liquid.  As shown, a sterilizer vessel 1 is heated by an immersion steam coil 2 supplied via control valve 3 from a steam generator (not shown), over part of which coil an elongated inverted trough 4 is disposed on the bottom of the vessel.  When the water 5 approaches the boiling point, vapour bubbles collect in a dome 6 forming part of the trough 4 and pass along a horizontal tube 7, from the end of which the bubbles are discharged into an elbow 8 mounted externally of the vessel 1 but projecting into the interior thereof and connected to the lower end of a small bore rising tube 9, the upper end of which is above the level of the water and is connected to a downwardly inclined tube 10 closed at the end 11 and connected with the interior of the sterilizer vessel at the other end by a drain connection 12, which permits water accumulating in the tube 10 to be returned to the sterilizer.  The tube 10 constitutes a housing for a bulb 13 of a thermostatic device 14, of the known bellows type operated by a bulb and capilliary tube, which is connected to the bulb 13 and leads to the device 14 which houses a bellows (not shown) arranged to operate a valve 16 controlling the flow of heating steam through a main inlet pipe 17 connected at 18 to the heating coil 2, the opposite end of which is connected to a steam trap 19.  In a modification the inverted trough 4, pipe 7, elbow connector 8 and pipe 9 are replaced by a simple form of inverted trough disposed in the same manner as the trough 4 but having connected to it at its highest point a small bore tube leading directly vertically to the bulb housing tube 10.
Patent GB-579064-A (GB)
Title: Improvements in or relating to the manufacture of wet-spun artificial threads or yarns
IPC: D01D10/04
Filed: 1943-12-14
Abstract: <PICT:0579064/IV/1> Wet spun artificial threads or yarns produced, for example, from viscose, are subjected to a continuous after-treating process wherein the freshly spun threads collected in package form are mounted, unwound at a rate of approximately 300 metres per minute and subjected during their travel over a plurality of thread-storage, thread-advancing devices to treatment with washing and finishing liquids and to drying, before being finally collected at a rate of approximately 300 metres per minute.  As shown in Fig. 1, freshly spun viscose thread 4 is unwound from package 3, washed on rollers 5, desulphurized on rollers 6, washed on rollers 7, finished on rollers 8, dried, under tension if desired, on heated rollers 10 and wound up at high speed by suitable traversing mechanism in the form of a conical package 13. The thread may be subjected to oiling or other treatment normally incident to cone winding in its passage between rollers 10 and the traversing mechanism.  The thread may be subjected to other treatments such as bleaching in the continuous operation, and adjacent pairs of treatment rollers may be driven at successively greater or lower speeds in order to stretch or relieve the tension on the thread.  The pairs of rollers 5, 6, 7, 8 and 10, one or both of which are driven, have their axes offset in order to advance the thread thereover in a helical path.  The coning spindle speed may be gradually decreased as the thread builds up on package 13.  In order to effect continuity, two adjacent cakes of freshly spun yarn may have their ends tied together so that when one cake is completely unwound, thread is withdrawn from the second cake.  The thread may be twisted by replacing the coning mechanism by a ring or cap twisting mechanism, the coning operation then being effected separately and subsequently.  If desired, the drying rollers and coning mechanism may be mounted in sequence above the finishing rollers 8 or alternatively the entire treating and coning operation may be effected with the thread moving downwardly.  The freshly spun thread may be produced by the two-bath process, wherein the thread is highly stretched in a heated bath prior to collection in a centrifugal pot or on a bobbin.
Patent GB-341391-A (GB)
Title: Improvements in processes for polymerising unsaturated hydrocarbon gases
IPC: C07C2/04
Filed: 1929-07-08
Abstract: Unsaturated hydrocarbon gases containing ethylene and its homologues are polymerized to form liquids suitable for motor fuels by subjecting the gases when under pressure to the polymerizing action of a heated reaction zone, then cooling and condensing the products without releasing the pressure, separating the condensed liquids from the lean gases, stabilizing the liquid by removing <PICT:0341391/IV/1> therefrom the excessively volatile compounds, and returning these compounds to the reaction zone.  The temperature of the reaction zone is between 800 DEG  to 1000 DEG  F. and the pressures employed vary between 300 and 1000 pounds per square inch. Catalysts are not essential, but the use of iron oxide is referred to.  As shown, a pipe line 4 communicating with a gas tank 2 leads to a compresser 5, which forces the mixed gases under increased pressure and at about 300 DEG  F. through a pipe 6 to a bank of preheating tubes 7 positioned within the outlet 8 of air furnace 9.  The gases then flow through the pipe 10 to a horizontally arranged row of tubes 11 placed in the roof of the furnace, which is heated by a burner 13. The desired reactions are effected within the tubes 11 and 17, the outlet pipe 19 leading to a cooling unit 20, which reduces the temperature of the gases and polymers to about 100 DEG  F.  The arrangement of these heating tubes is such as to provide an automatic control of the reaction temperature, since the temperature of the flue gases in the chamber 15 is arranged to be below the temperature of the gases passing through the tube bank 7.  The coil 20 communicates with the accumulator tank 22, which has a gas outlet pipe 24.  Liquid is withdrawn through the pipe 26 and passes into a stabilizing tank 28, excessively volatile compounds being discharged through a pipe 29 leading into the pipe line 1; the lower part of the tank 28 may be provided with a boiler coil 30 and with a draw-off line 31 leading to a storage tank 32.

Title: Improvements in electric light fittings of the candle type to provide for adapting any universal type of bayonet catch electric lamp and their easy adjustment
IPC: F21S4/00
Filed: 1926-08-26
Abstract: 275,424. Smith, J. F. Aug. 26, 1926. Candles, imitation.-In electric candle-lamp fittings of the type in which the lamp bulb 3 is mounted in a lamp-holder 4 carried by a central tube 5 secured to a socket 1 which is supported by the bracket of the electric light fitting, and in which an outer tube 2 made in imitation of a candle is spring-pressed upwardly against the bulb, the lower end of this outer tube 2 is arranged to be guided by the socket 1. As shown, the socket member 1 comprises two screwed-together parts, the upper part being in the form of a sleeve adapted to receive the lower end of the tube 2 supported upon a disc 7 having a central hole for the passage of the inner tube 5 which is rigidly secured to the socket 1. A spring 8 presses the disc 7 and tube 2 upwardly, a flange 9 around the open end of the socket 1 preventing the tube being completely forced out of the socket. The spring 8 may bear against a collar 10 screwed on the inner tube, or may engage the bottom of the socket. In a modification the socket 1 is made in one piece without the flange 9 and the movement of the disc 7 is limited by a collar on the inner tube 5. The disc 7 may be replaced by an internal flange at the lower end of the tube 2, and the spring 8 may, in a further modification, be arranged between the attachment ring of the lamp-holder and an internal flange at the upper part of the tube 2. The socket may comprise two telescopic members forced apart by a spring, the upper part carrying the tube 2.
