Filed: 1929-12-17
Abstract: 339,129. Debauche, H. Dec. 17, 1929. Coking processes and apparatus. - Lignite is destructively distilled, in an apparatus of the kind described in Specification 270,921, first at low temperature (300‹-500‹ C.), and then at a higher temperature (800‹ C.), for removal of heavy hydrocarbons, and production of a coke which is clean and brilliant. Briquettes or ovoids made from this coke with admixture of 7¢ per cent of pitch and with a pressure of 225 kilos per square centimetre, are stated to possess great adhesion, to be resistant to water, to be highly combustible, and to burn without disintegration. A suitable retort for carbonizing the lignite comprises a central chamber formed of superimposed rings a spaced apart to allow the distillates to escape from the annular layer f direct to the outlets e, the fuel being fed from a hopper b, and the coke withdrawn from the lower end c. The thickness of the layer f of fuel is reduced at the lower end g.
Patent GB-857073-A (GB)
Title: Improvements in epoxy resin compositions
IPC: G01N21/90
Filed: 1956-12-19
Abstract: Epoxy resins are cured by heating with a polyalkylene ether diacid ester having a skeletal chain with at least three consecutive alkylene ether groups.  A typical curing agent is formed from one mol of polyethylene glycol and two mols of maleic anhydride and has the formula HOOC CH = CHCOO(CH2CH2O)n COCH = CHCOOH. wherein n is at least 3.  Polypropylene glycol is also suitable.  If desired the polyalkylene glycol and diacid or anhydride may be mixed with the resin, the diacid ester being formed in situ.  The thermosetting compositions may also include a polycarboxylic acid or anhydride e.g. an alkenyl succinic anhydride such as tetrapropenyl succinic anhydride.  The compositions may be dissolved in volatile organic solvents or dispersed in aqueous media, and may include fillers e.g. carbon black, zinc sulphide, micalith talc, asbestos fibre, powdered inert resins or powdered metal.  In the examples the composition unsually includes dimethylbenzylamine, trisdimethylaminomethyl phenol or the tri-quaternary salt of the latter with 2-ethyl hexoic acid. Example 6 uses a diacid ester from polyethylene glycol and diglycollic acid.  Example 10 uses a mixture of polyethylene glycol and phthalic anhydride to form the diacid ester.  The composition in this example is used to impregnate strands of glass fllaments which were formed into webs for the manufacture of laminates.  The preferred epoxy resins are made from epichlorydrin and bisphenol or glycerine.  Epoxidised oils or epoxidised butadiene copolymers may also be employed.  The products are also useful as casting resins or for encapsulating electrical products.  The curing agents act also as plasticizers and the compositions have low viscosity, long shelf life and cure rapidly to strong, tough, heat-resistant products.

Abstract: 956,619. Sifting apparatus. P. DRUMMOND. (Separator A.B.). Oct. 30,1961, No. 38722/61. Heading B2H. In a method for separating particles of different size from a flowable mass, horizontal, vertical and gyratory motion components are imparted to a resiliently supported receptacle having a vertical axis and the particles to be separated are fed vertical on to the receptacle along the axis, initially separating the smaller size particles from the mass adjacent the vertical axis while a small vertical component only is imparted to the particles and then separating particles of a large size from the remaining unseparated mass while a larger vertical motion and a substantial horizontal motion are imparted to the larger size particles. In the arrangement shown a conical screen 32 and a horizontal annular screen 30 are arranged in an assembly 14 supported on springs 13 and to which assembly a gyratory motion is imparted by an apparatus 24 driven by a motor 25. Material fed through a tube 21 to the apex of the screen 32 is initially separated on the screen 32 and the balance is separated on the screen 30. The material remaining above the screens 32,30 passes through a discharge duct 22 and the separated material passes through a duct 19. The screen 30 is clamped between annular rings at its outer periphery and between annular rings 34 at its inner periphery which rings 34 are supported between angle members 38, 39 carried by brackets 41 carried by spider arms 43. The preformed screen 32 is attached between flanges 46 at its upper end and is supported by wires 40. The screen 30 may be tensioned by a nut 74, Fig. 4, threaded on a spindle 31 and bearing against a nut 70 threaded on a sleeve 68 slidable on the spindle 51 and bearing against a tubular member 60 supporting the arms 43. In a further embodiment, Fig. 5 (not shown), provision is made for tensioning the conical screen 32 which is gripped between angle member 38 and an outer ring at its lower end and between plates at its upper end, screw means being provided to move the upper plates relative to the arms 43.

The rotor 41 houses the motor armature laminations 43 and windings 44, has a flange 45 forming an end wall of the pump, and a slotted portion 46 housing rollers and is biased against a plate 40 by springs 19 which bear against carbon brushes 18. The plate 40 is apertured to provide pump inlet and outlet ports communicating with inlet 29 and outlet 30 respectively, the outlet being communicable with the inlet via an annular recess 35, an adjustably biased ring 39 and a chamber 34. As a further safeguard, the rotor 41 may move against the springs 19 to connect the inlet and outlet ports via the liquid-filled chamber 9. In a modification, Figs.3 and 4 (not shown) the ring-valve is dispensed with, and the output pressure at which the rotor 41 lifts off to shortcircuit the pump is controlled by varying the size of a throttling aperture connecting the interior 9 of the casing to the pump inlet, and in the embodiment of Fig. 5 (not shown), communication between the interior 9 of the casing and the pump inlet is via a spring-loaded annular valve.

[Class 117.] An electromagnetic vibratory device for operating a screen or like apparatus comprises an electromagnet, an armature which is urged away from the electromagnet by a spring, and a buffer plate in the path of the armature provided with a cushioning spring supported independently of the armature spring. The armature may be attached to a resilient guide strip and spring means may be provided to take up the weight of the screen and its load of material. In the form shown, the electromagnet 12 is contained in a box-like portion 11 of a frame 10 which is mounted on the casing 1 in which the screen 2 is housed, and the armature 13 is attached to the screen by a rod 15. A spring 18 between the underside of the armature and the bottom plate 16 takes the weight of the screen and load. Two extensions 14 of the armature straddle the magnet and are united by a cross-bar 19 on which bears a spring 20. By means of a handoperated screw 22 this spring may be adjusted to hold the armature away from the magnet, when de-energized, for any difference in the load of material on the screen. The armature buffer plates 31 are threaded on pairs of rods 24 between springs 29, 33 and sliding collars 30, 32, adjustable shims 26, 35 being provided for regulating the pressure of the springs. Normally, the armature lies below the level at which the buffer plates are supported by the springs 29, and when the magnet is energized it rises smartly against the buffer plates so as to give to the screen a jar which is cushioned by the springs 33. These springs are so adjusted as to stop the armature just before its striking-plates 3'7 meet the adjustable weaving- plates fixed in the casing when the current reverses, the buffer plates move downwards with the armature until they are arrested by the springs 29. The armature may carry on its lower surface a resilient guide strip 40, the edges of which are seated in recessed blocks 42 of resilient material which are bolted to the casing. The wire screen 2 has reinforced edges 3 which take over brackets or angles 4 adjustable in the frame for tensioning the screen. The bracket 7 for attaching the screen to the armature is mounted on metal plates 5 bolted to the screen.
