Title: Resinous polyolefin treatment
Filed: 1963-03-04
Abstract: <PICT:0967227/C3/1> In a process for separating a resinous polymer of a normally gaseous olefine or olefines from a solution of said polymer in a normally liquid hydrocarbon solvent, which solution contains up to 20% by weight, based on the weight of the dissolved resinous polymer, of grease to wax-like, waxy, polymer of said olefine or olefines preferentially soluble in said solvent, the said solution is cooled to form a polymer gel containing substantially all of the resinous polymer and waxy polymer contained in said solution and the gel is then subjected to mechanical compression to express a liquid which is a solution of said waxy polymer in said hydrocarbon solvent.  The resinous polymer concentrate recovered contains a reduced ratio, on a weight basis, of the waxy polymer to resinous polymer. In the drawing a solution at 170 DEG  to 190 DEG C. of ethylene polymers in naphtha which has previously been filtered or otherwise treated to remove catalyst residues, is introduced through line 10.  The total polyethylene concentration in the solution may range from 2 to 45% by weight. If the polyethylene concentration is 5% or less the solution is preferably concentrated by diversion through line 11, heater 12 and solvent distillation zone 13, sufficient solvent being withdrawn to increase the polyethylene concentration to 10 to 40% by weight and the polymer melt formed in the lower portion of 13 is passed via line 16 to line 17.  If the polyethylene concentration is originally between 10 and 40% by weight, the solution is passed from line 10 directly to line 17.  If the polyethylene concentration in the solution in line 17 is below 10% by weight, the solution is pumped via cooler 20 to filter 21 and the recovered filter cake passed along line 22.  In either case, the cooled concentrated solution is passed to equipment 25 which can be a continuous mechanical screw press or equivalent batch or continuous oil expression device and is usually operated between 25 DEG  and 60 DEG C. and exerts a pressure of at least 25 p.s.i.g. The gel is torn and compressed and the polyethylene resin concentrate is moved forwards and solvent is removed through the interstices in a wall made of closely fitting cylindrical pieces of metal 26; solvent is removed through line 27.  Part of the pressed resin withdrawn from 25 may be recycled.  Specifications 734,501, 748,634, 753,349, 763,350, 799,823 and 832,207 are referred to.

Patent GB-902338-A (GB)
Title: Hydrogen production
IPC: C01B3/10
Filed: 1959-03-12
Abstract: In the production of pure hydrogen by the reaction of steam on finely divided iron free from carbon, the iron is regenerated by passing the resulting iron oxide to a reduction zone wherein a mixture of 60-95% of iron and 5-40% of iron oxide is maintained, reduction being effected by means of methane with by-product formation of fuel gas comprising hydrogen and carbon monoxide, and freeing the resulting iron from carbon.  Carbon dioxide produced by the oxidation of coke with air or oxygen at a temperature of 500 DEG -700 DEG C. may be admixed with the methane to reduce carbon deposition.  Carbon deposited may be removed by stripping with steam.  The iron-steam reaction may be carried out at a temperature of 500 DEG -600 DEG C. and a pressure of 1-100 atmos. preferably 10-50 atmos.  The regeneration reaction may be carried out at a temperature of 600 DEG -850 DEG C. and a pressure of 1-3 atmos. In a fluidized process the solids particle size may be 20-200 mesh, the fluidized bed density may be 10-15 lb./cu. ft., and the linear gas velocity may be 0,1-5 ft./sec.  A plurality of batch operated hydrogen generators, e.g. 4, may pass iron oxide in succession to a single regenerator (Figs. 1 and 2, not shown). Alternatively, a single generator may be operated continuously (Fig. 3, not shown).

Filed: 1929-03-18
Abstract: 333,590. Vicars, Ltd., T. & T., and Crosland, E. M. March 18, 1929. Coating bakers' goods.-The biscuit carriers of a machine for applying icing or the like to biscuits or the like of the kind described in Specification 300,335 are provided with a resilient means which keeps the biscuit accurately positioned thereon. As shown, the carriers 5 have an upturned transverse edge against which the biscuit is pressed by a leaf spring 11 which projects above and moves in a slot in the carrier 5. Each carrier 5 is mounted on a stem 6 slidable in bearings 7 on a bifurcated bracket 8 secured to the conveyer chain 9. The stem is normally pressed downwardly by a spring which bears on a sleeve 10 clamped to the stem 6. The sleeve 10 carries the leaf springs 11 and a lever 14 pivoted to the lower bearing 7 engages cam rails 19 at intervals along the conveyer track, and is thereby swung to press the spring 11 away from the biscuit which is thus released for transverse alignment by adjustable guides 28 or, for discharge from the carrier which is effected by depending projections 31, Fig. 6, on the disc 3 after the cover biscuits 34 have been applied by the disc 33. The stems 6 are raised to lift the carriers 5 to receive the biscuits, icing or cover biscuits by cam rails 20, the rail 20 at the icing position being resiliently and adjustably carried by springs 24 and screws 25, 27. The biscuit magazines 2 are curved in elevation as shown in Fig. 8, to relieve the lower biscuits from the weight of the pile, and the front slot 32 is wider at the top to facilitate the insertion of the biscuits.

IPC: G01R31/50
Filed: 1966-02-28
Abstract: 1,065,703. Testing non linear resistors in surge diverters. LICENTIA PATENT -VERWALTUNGSG.m.b.H. Feb.28, 1966, No. 8640/66. Heading G1U. In a method of synthesising the effect of a train of current surges on a non linear resistor having negative temperature coefficient, which resistor may be in a surge diverter 12, a train of similar current surges from a surge current generator is applied to the resistor and the charging voltage of the generator is adjusted between successive surges to vary the surge current amplitude from one surge to the next, to simulate the effect that automatically occurs when a constant voltage source of surges is applied across the resistor in operational practice. A surge current generator 8 is charged at intervals by closing the switch 5 operated by the control unit 1 so that A.C. is passed via the transformer 6 and rectifier 7 to the generator 8. The spark gap 9 is triggered from the control unit 1 to pass a current pulse to the surge diverter 12. The residual voltage across the negative temperature coefficient resistors is compared in the unit 11 with the expected voltage, and if it lies within acceptable limits, the control unit proceeds normally to operate the timing relay 2 and the motor 3 to adjust the potentiometer 4 by a required discrete amount. This adjusts the surge generator charging voltage prior to the next applied surge in the train. If the residual voltage has an abnormal value, the control unit is stopped or speeded up as appropriate.

Abstract: 1,094,142. Valves. DURIRON CO. Inc. March 2, 1965 [March 4, 1964], No. 8942/65. Addition to 1,063,852. Heading F2V. The body 301 of a tapered plug cock has opposed ports 294, 296 and houses the plug 300 which embodies a through-passage 306 and is supported upon a plastics bearing-block 307. The body is closed by a cap 310 that retains an annular thrust-diaphragm 315. Recesses 325, 330 are formed in the body around the junction of the ports 294, 296 with the plug bore to house inserts 335; with the outlet port 296 closed the passage 306 is open to the inlet port 294 to balance the pressure on the associated insert 335 and prevent movement of the unsupported parts thereof hence the inlet port 294 is both shorter in the direction of the plug axis and wider in the transverse direction than the outlet port 296 although the flow area of the two ports is equal. Alternatively, the upstream side of the plug may be chamfered, the port in the inlet insert may have a transverse dimension greater than the inlet port itself, or a bleed hole may be provided through the plug to maintain the pressure in the plug passage 306 equal to that upstream thereof. The valve requires a low operating torque only. Each recess 325, 330 includes and is completely surrounded by an expansion chamber  340 and a peripheral wall 341 which result in  high-pressure seal-areas 342 (Fig. 4, not shown) surrounding the related ports whilst each expansion chamber provides a low-pressure seal-  area around each high-pressure area 342. The bore and recesses may include a patterned or embossed surface which is transferred to the inserts upon assembly (Fig. 6, not shown). In a modification (Fig. 7, not shown) an annular shoulder surrounds each port and is ef smaller radial dimension than the associated recess so preventing movement of the insert.

Abstract: 574,363. Parachutes. QUILTER, J. R. C. June 8, 1943, Nos. 9199 and 19182. [Class 4] A parachute pack for loads to be dropped from aircraft comprises a container enclosing main and auxiliary parachutes, and is provided with a carrying cradle normally fastened to prevent extraction of the parachutes, the cradle being attached to the static line and its fastening means being controlled by lift webs attached to the load, so that the pull upon the lift webs releases the fastening means after the static line has been drawn taut. In the construction shown, the upper compartment 11 of the pack is occupied by a pilot parachute of the type described in Specification 531,884 and a larger retarder parachute, the lower compartment 10 housing three main parachutes whose shroud lines are connected to lift webs 34 for attachment to the load. The carrying cradle cpmprises upper straps 67, 68, connected by toggles 73, 74, to lower straps 70, 71, a handle 72 connecting the straps, which are attached at the top of the pack to the main static line 22. In operation, descent of the load L first tensions the static line 22 to release the cradle fastenings 73, 74, the lift webs 34 of the main parachutes being pulled from the bottom of the pack 10 for a predetermined distance as permitted by beckets 40 secured to the pack by a cable 39. Further descent tensions a second static line 21, thus withdrawing retaining pin 20 from the flap of the upper compartment 11 to permit release of the pilot parachute 59, which may be provided with an ejector board 56 of the kind described in Specification 531,882, and then the retarder parachute 49. The pilot parachute becomes detached from a lazy cord 64 and the tension of the retarder line 53 withdraws a ripcord pin 45 from the cables 39 by means of a release wire 46, thus opening the bottom of the lower compartment 10 to permit withdrawal of the main parachutes 26 under the action of the load.
