Title: Process and apparatus for devolatilizing polymeric materials, especially alkenyl aromatic polymers
Inventor: HUNT WILSON WESTLE
IPC: B29B13/06
Filed: 1959-09-18
Abstract: <PICT:0888716/IV (a)/1> Polymeric materials, especially alkenyl aromatic polymers such as polystyrene and polyvinyl toluene, are devolatilized by heating the material to the devolatilizing temperature while contained in an enclosed space, and flowing the molten material downwardly and in the form of a continuous coating on an exposed surface such that the volatile material can escape.  A suitable form of apparatus for carrying out the process is shown in Fig. 1 which consists of a polymer feed section 6, a heating section 11 and a devolatilizing chamber 13.  The polymeric material is admitted through inlet 5 to be distributed to the heating tubes 8, after which it flows downwardly through the conical devolatilizing chamber 13 as a thin coating over its heated, bare metal walls 12 whence it is discharged through outlet 17, the volatile materials passing through the upright vapour conduit 14.

Filed: 1936-11-23
Abstract: 478,087. Implements for working land. ARCHIBALD, W. Nov. 23, 1936, No. 31965. [Class 6 (i)] A harrowing device for levelling gravel &c. comprises a base part or frame provided with pins or teeth and a handle the point of connection of which is displaceable from front to rear of the frame, so that the direction of travel can be reversed without turning the harrow round.

Title: Production of inert atmospheres in storage vessels, fuel tanks and the like
Inventor: KEEPING WILLIAM OWEN
IPC: B64D37/10
Filed: 1957-10-14
Abstract: 833,898. Preventing fires and explosions. BRITISH OXYGEN CO. Ltd. Oct. 1, 1958 [Oct. 14, 1957], No. 32092/57. Class 47 [Also in Group II] An inert atmosphere in a storage vessel containing an inflammable liquid such as petrol, liquid alkali metal, molten titanium &c., is produced by feeding liquefied inert gas into the inflammable liquid in a finely divided state and in widespread dispersal in the liquid, evaporation of the liquefied gas being effected by heat exchange between the liquefied gas and the inflammable liquid. In the exemplified embodiment liquefied nitrogen from an insulated vessel 16 passes along an insulated conduit 13 to an elongated injection member 10 located in the base of an aircraft fuel tank 12, the member 10 having multiple small outlets 11 for dispersing the liquefied nitrogen into the fuel. Pressure within the vessel 16 by which the liquefied nitrogen is forced into the tank 12 is due to vaporization of some of the liquefied nitrogen in the vessel 16 due to natural influx of ambient heat or internal heating by an electric heater 21 or an internal coil pasing hot fluid medium. A relief valve 22 prevents the pressure differential of the tank 12 over the ambient pressure from exceeding a predetermined value. A flow control valve 23 in the conduit 13 is operated by a pressure sensitive device 24 in the tank 12 so as to open when the pressure differential of the tank 12 over the ambient pressure falls below a predetermined value.

The needle 2, having a point 5, is formed with a shank 3 of reduced diameter so as to leave a shoulder 4 against which the leading end of the tube 6 is placed, so as to facilitate entry of the tube. The needle is withdrawn by holding the rear end 8 of the tube, which is preferably widened to receive a syringe nozzle, and pulling the needle rearwardly by a handle 10. In a modified form the needle and tube are normally enclosed in a cover which may be reversed for use as a handle, (see Fig. 4 not shown). Other forms of needle are also described which include a fine bore in the needle, to allow blood to pass and indicate when a vein is reached, and a separate sleeve on a small diameter shank of the needle, to grip the tube during insertion or to hold a resilient stop extended in place of the shoulder of Fig. 1, until it is required to withdraw the needle.

Title: Improvement in waste heat steam boilers
IPC: F22B1/18
Filed: 1946-11-06
Abstract: 624,722. Heating steam boilers by waste gases. TRIGGS. W. W. (Maxim Silencer Co.). Nov. 6, 1946, No. 33009. [Class 123(ii)] A waste heat steam boiler, e.g. in the form of a jacket 21 surrounding an internal combustion engine exhaust silencer 11, adapted to run dry when there is no steam demand, has feed-water supply and return or drain pipes 40, 41 which lead through a common pipe 42 to a spring pressed valve 34 which is actuated by the boiler steam pressure to control the pipe 42 and also pipes 43 and 46 leading from and to a feedwater supply tank 29. The pipes 40, 41 are provided with check valves 38, 39 respectively which permit flow therethrough in the direction of the arrows, and a feed pump 27 is located in the pipe 43, said pump being coupled to an electric motor 26 the switch 25 of which is controlled by a float disposed in a chamber communicating with the boiler. As shown, the pipe 40 opens into the upper part of the boiler and terminates in a circumferentiallyextending spray pipe 47, or a simple spray head, and the boiler has a steam outlet 28 leading to a heating system &c. from which condensate may be returned to the tank 29 through a pipe 30. The arrangement is such that when the steam demand falls the pressure increases, and this pressure is communicated by a pipe 35 to the valve 34 which moves to the position shown in Fig. 4 to mate the pipes 42, 46 so that water from the boiler is returned to the tank 29. An increase in steam demand, however, causes the pressure to decrease and the valve 34 to move to mate the pipes 42, 43, whereupon water will be pumped back into the boiler until the switch 25 is opened. The pipe 43 is connected to the Lank 29 through a relief valve 44, and the tank 29 is provided with a make-up water pipe 31, controlled by a float valve 32, and a vent 33.

This stage is followed by a similar transductor whose control windings 8, 8<SP>1</SP> derive their energization from the rectified output of the previous stage, and whose output circuit contains a common resistor 17, the voltage across which is fed to the bias windings 6, 6<SP>1</SP> of the first stage to produce a current in opposition to that derived from the source 11. Alternatively the resistor 17 may be omitted ; or windings 6, 6<SP>1</SP> may be fed from source 11 only, and one duplicate set of windings introduced fed from the combined output of the second stage (Fig. 2, not shown), or two duplicate sets of windings introduced each fed from the output of each part of the second stage (Fig. 3, not shown), the additional windings opposing the existing windings 6, 61.

The upper rolls 71-73, Fig. 4, are mounted in a roll assembly 18 comprising block members 78, 78<SP>1</SP> and 78<SP>11</SP>, the block members 78 and 78<SP>1</SP> having three bearing receiving portions 76 and 76<SP>1</SP>. Each of the upper rolls is vertically adjustable and since the means for vertically adjusting each of the rolls is similar, only the adjusting means for roll 73 is described. An hydraulic cylinder 90, Fig. 5, mounted on a member 92, is biased upwardly to support the block members 78 via a member 86 and the roll 73 is adjusted vertically by movement of screw operated wedges 96 towards or away from each other. The horizontal position of the member 86 is determined by the relative position of a movable wedge 106 to a fixed wedge 108 and the upper roll assembly 18 is clamped to the main frame 14 by a wedge 113. The lower rolls 41-44 are mounted in block members 46, 48 mounted on a sled 60, the sled being vertically adjustable by means of wedges 120 and 122, Fig. 4. The sled 60 is locked on platform 62 by engagement of a wedge 144 with an opening 148 in the sled. The roll 72 is driven by a motor 150 via gear assembly 152 and shaft 154, the shaft being supported by a vertically adjustable collar. Similarly each of the rolls 71, 73 is driven by a motor 170 via a gear assembly 172 and a shaft, the motor and gears being mounted on a sled 180, Fig. 6, which is movable on an inclined surface 181 so as to accommodate movement of the roll from one bearing receiving position to another. Replacement of the upper and lower roll assemblies is effected by moving the assemblies along rails 35-37 on to a trolley 32. In other embodiments (Figs. 12-15) pinch rolls are placed on the entry side of the straightener.
