Patent GB-802061-A (GB)
Title: Suspension polymerization
IPC: C08F2/20
Filed: 1956-02-27
Abstract: Polymeric granules are prepared by mixing one part of a polymerizable liquid with at least 0.5 part by volume of an aqueous non-solvent liquid medium and a water-insoluble solid material, capable of being dispersed as colloidal particles of size 0.1 to 50 microns and having a balance of hydrophilic-hydrophobic properties such that the particles tend to collect in the aqueous medium at the water-oil interface, in amount barely to cover the surfaces of the polymerizable liquid when the latter is in the form of droplets of the desired size, agitating to disperse the polymerizable liquid as droplets smaller than those desired, allowing limited coalescence under quiescent conditions, optionally increasing the apparent viscosity of the medium by adding a water-dispersible thickening agent to prevent movement of the droplets under gravity, and then subjecting the dispersion without turbulence to conditions conducive to polymerization.  The polymerizable liquid may comprise one or more vinylidene compounds, e.g. styrene, p-chloromethyl styrene, divinyl benzene, acrylic and methacrylic esters, vinyl and vinylidene halides, e.g. vinylidene chloride, and may contain plasticizers and preformed polymers.  Specified colloidal materials are metal salts and hydroxides, clays, e.g. bentonite, raw starches, sulphonated cross-linked high polymers and resinous polymers.  They may be swollen and hydrated provided they retain a definite shape.  The aqueous medium may contain: (1) water-soluble promoters which affect the hydrophilic-hydrophobic balance of the colloidal particles, e.g. sulphonated polystyrenes, alginates, carboxymethylcellulose, tetramethyl ammonium hydroxide or chloride, condensation products of diethanolamine and adipic acid, ethylene oxide, urea and formaldehyde, and polyethyleneimine, gelatin, glue, casein, albumin, glutin and methoxy cellulose; (2) electrolytes, e.g. aluminium and calcium salts and copper sulphate; (3) peptizing, flocculating, deflocculating and surface-active agents and sensitizers; and (4) water-soluble, oil-insoluble polymerization inhibitors.  The thickening agent may be sulphonated polystyrene, hydrophilic clays, e.g. bentonite, digested starch, natural gums and carboxy-substituted cellulose ethers.  The dispersion may be concentrated by creaming and the thickening agent added as an aqueous concentrate. Monomer-soluble, water-insoluble catalysts, e.g. benzoyl peroxide, may be added to the polymerizable liquid before dispersion.  The process is suitable for continuous or batch polymerization, e.g. by heating with gentle agitation to assist heat transfer.

Title: Improvements in or relating to the Breech Mechanism of Ordnance.
Inventor: DAWSON ARTHUR TREVOR
IPC: F41A3/10
Filed: 1917-04-28
Abstract: 127,611. Dawson, Sir A. T., and Buckham, Sir G. T. April 28. 1917. Ordnance brcech mechanism.-Relates to the wedge type in which the hand-lever is pivoted to the block and turns in a transverse plane about a fulcrum on the gun during the whole of its movement to open and close the breech. According to the invention, the hand-lever is pivoted to the breech-block by a hollow spigot, which receives the striker of the firing-mechanism, and is fulcrumed to the gun by a pin-and-slot device. In the form shown in Figs. 1 and 2, the breech-block A' is moved transversely in the gun A by operating, between stops E<x>, E<1>, a hand-lever B pivoted to the block and slotted to engage a detachable pin B<x> on the gun. In a modification, a pin on the lever engages a vertical slot in the gun. The firing-mechanism is carried by the hand-lever and is dismounted therewith when interrupted threads on the hand-lever boss b are disengaged from the block. The striker C, the head of which may be detachable, is retracted by a toe d‹ on a lever D when the hand-lever is gripped, and at the same time a projection D<2> on the retracting-lever D is removed from a recess A<2> in the block. As the block is moved to the open position, the projection D<2> moves on an incline A<3> and cocks the striker into engagement with the sear C<x> pivoted at c<x> to the hand-lever, the projection D<2> then passing into a recess a<3>. A handle C<0> serves to cock the striker in case of misfire. The extractor ex is operated by inclines during the opening movement, and a spring on the stop E<x> allows a slight movement of the block towards its closed position to permit the extractor to rock when a cartridge is inserted. When the breech is closed, the gun is fired by a plunger C<1x> which rocks a firing-lever C<1> on its pivot c<1>, and thereby releases the sear C<x>.

Abstract: 249,457. Aktiebolaget Separator. March 18, 1926, [Convention date]. Density separators; cleaning drums.-Deposited sludges or other solid impurities are removed from a centrifugal separator drum, used for purifying liquids, by liquid, steam, or gas introduced under pressure through one or more of the ordinary discharge or supply openings. The cleansing medium may be supplied, after the bowl has stopped, to the distributing tube C, and the deposit is washed out through the holes G, H; or the cleansing medium may be supplied through the opening H to clean the liner discs. Water may be supplied through the tube C and all the openings shut; steam is then supplied through the opening H until the temperature of the liquid is above the normal boiling-point. The orifice G is opened and the consequent reduction of pressure causes a violent boiling in the sludge which assists the cleaning operation. A hood i for the bowl may be screwed on the tube C and is so shaped that there is no communication between the openings C, G. H. Pipes j, L with valves K, M are connected to the openings C, H for the supply of the water and steam. The impurities pass out through the openings G. N. Oil with air or other gas may be used for cleansing instead of water and steam.

Title: Improvements relating to means for influencing the inclination of vehicles on curves
IPC: B60G21/10
Filed: 1959-02-23
Abstract: 879,178. Preventing lateral cant of road vehicles. DAIMLER-BENZ A.G. Feb. 23, 1959 [Feb. 21, 1958], No. 6210/59. Class 108(2). Lateral movement of a road vehicle body due to the effect of centrifugal force on negotiating a bend is used to develop forces which resist rolling movement of the body. The correction may be sufficient to induce a rolling movement in the opposite direction to that which would normally result from the centrifugal force. In Fig. 1, the body 11 is movable on rollers 12 relatively to an auxiliary frame 10. This movement results in deflection of a linkage 26, 27, 28, connected to arms 20, 21, which are respectively welded to the bottom wishbone links 15, 17, of the wheel suspensions at opposite sides of the vehicle. In the construction shown in Fig. 2, swing axles 32, 33, are pivoted at 34 to a link 35 which is pivotally connected at 38 to a link 36 itself pivoted to the body at 37. Springs 30, 31, act between respective abutments on the body 11 and the pivot 38. A hydraulic piston and cylinder device 40, 42, is connected between the axle 32 and a pivot point 30 on the link 35. A similar device 41, 43, is connected between the pivot point 39 and the axle 33. The cylinders of the devices 40, 42 and 41, 43 are connected by respective conduits 46, 47, to respective cylinders 49, 50, in which operate pistons 51, 52, which are coupled together and are inwardly urged into the cylinders by a common spring 53. In the construction shown in Fig. 4, the coiled suspension springs 18, 19, of Fig. 2 are replaced by hydropneumatic spring units 54, 55, respectively, and the link 35 is pivoted directly to the body 11 at 62. A double acting piston and cylinder unit 66, 67, is connected between the link 35 and the body 11 and has its working chambers on opposite sides of the piston 64 connected respectively to the liquid chambers of the hydropneumatic suspension units 54, 55. In a further construction (Fig. 3, not shown), the body is mounted on rollers on an auxiliary frame from which the road wheels are suspended by upper and lower wishbone links as in Fig. 1. The coiled suspension springs 18, 19, of Fig: 1 are replaced by hydropneumatic suspension units similar to those shown in Fig. 4. Each hydropneumatic suspension unit is connected to a respective hydraulic piston and cylinder unit connected between the body 11 and the auxiliary frame. The conduits connected between hydropneumatic suspension units and hydraulic piston and cylinder units in each case may be provided with throttling ducts.

Title: Improvements in or relating to the control of the catalyst-oil ratio in the catalytic cracking of hydrocarbon oils
IPC: C10G11/18
Filed: 1942-05-08
Abstract: 558,984. Catalytic conversion of hydrocarbon oils. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. May 8,1942, No. 6252. Convention date, May 9, 1941. [Classes 1 (i) and 32] [Also in Group XXIX] In processes for the catalytic cracking of hydrocarbon oils of the kind in which a suspension of oil vapours and catalyst is passed through a heated reaction zone, the ratio of vapours to catalyst in the suspension is maintained constant by passing the suspension through a Venturi nozzle or like orifice at which a pressure differential is developed and utilizing departures 'from the pre-arranged pressure differential to control the supply of catalyst to the catalyst and oil mixing chamber. The hydrocarbon stock is vaporized in a coil 14 and mixed in an injector chamber 22 with catalyst recycled from a hopper 98 through a line 24 controlled by a valve 36. The suspension passes to a reaction chamber 28 and thence through a line 32 provided with a Venturi nozzle 34 at which point a pressure differential is developed which is utilized to operate the valve 36 through a control circuit as shown in Fig. 2, [see Group XXIX]. The cracked vapours pass through a separator 38 from which catalyst is removed and passed by an injector 52 and line 56 to a collecting chamber 62 where further separation of vapours is effected, the combined vapours passing to fractionating and recovery plant through line 70. The catalyst falls through a stand pipe 72 where it is aerated by steam &c. supplied through lines 74, 76, 78, 82 and is then mixed with oxidizing gases from a line 86 and fed to a regenerator 92 the regenerated catalyst passing through a further separator 96 to a feed hopper 98 provided with a stand pipe 24 supplied with steam through manifold 106 and spaced points 108, 110, 112. Part of the catalyst may be passed through a by-pass 114 and lines 134, 136 with or without heating in coil 132 to mix with the catalyst passing to the regenerator 92 thus controlling the temperature in the regeneration zone and preventing it from rising above 1200‹F.
