Title: Improvements in or relating to Coke-ovens or the like.
IPC: C10B5/06
Filed: 1918-07-09
Abstract: 129,432. Marr, J., Colquhoun, W., and Coke Oven Construction Co. July 9. 1918. Coke ovens.-In an horizontal flued coke oven, the air for combustion is supplied through two sets of passages J, L, one set leading from the bottom and admitting air to the flues of the lower half of the heating-wall, and the other leading from the top and supplying the flues in the upper half. By this arrangement, the cross-section of the airpassages, and consequently the thickness of the heating-wall, may be reduced. The vertical air passages and the ends of the heating-flues C may be correspondingly tapered as shown in sectional plan in Fig. 2.

Abstract: 1419128 Reflex light reflectors; polyester points KOPPERS CO Inc 12 Dec 1972 [5 Jan 1972] 11295/75 Headings C3P and C3R [Also in Division G2] A reflex light reflector comprises a light reflective surface and a multiplicity of clear particles in the form of substantially perfect spheres of a thermoset polyesters resin which is an ethylenically unsaturated polyester cross-linked with an ethylenically unsaturated cross-linking agent, which particles are affixed to the light reflective surface, the particles being arranged so that when light strikes the particles the light passes therethrough and is reflected by the light reflective surface back through the particles and towards the source of light. By "clear" is meant substantially free of a milky or cloudy appearance and substantially free of white or other colour. The light reflective surface may be on a trafficway, e.g. a light reflective paint adhering to the surface of the trafficway. The paint may be applied to the trafficway, the particles applied to the paint before the paint dries and the paint allowed to dry to cause the spheres to adhere to the paint. Alternatively a composition comprising a light reflective paint having the particles dispersed in the paint may be applied to the trafficway. In the examples unsaturated polyesters prepared from propylene glycol, dipropylene glycol, isophthalic acid, maleic anhydride, phthalic anhydride, propoxylated bisphenol A, propoxylated tetrabromobisphenol A and fumaric acid are cross-linked with styrene and methyl methacrylate in aqueous dispersion in the presence of sodium chloride, polyvinyl alcohol, t-butyl peroctoate, lauroyl peroxide, 4-dodecyloxy-2-hydroxybenzophenone and 2-(2-hydroxy-5-methylphenyl)benzotriazole. The cured particles are separated, washed and dried. The particles of Example 35 are water-proofed with a mixture of dimethyl dichlorosilane and trimethyl chlorosilane. A coating of conventional white, traffic marking paint is sprinkled with particles and dried. In Examples 38 and 39 a composition comprises rutile titanium calcium pigment, calcium carbonate, suspending agent, medium length soya oil-phthalic anhydride, air dry type alkyd, V.M. and P. naphtha, driers and antiskinning agent and the particles.

Patent GB-668994-A (GB)
Title: Process for the purification of adrenalin
Filed: 1950-05-11
Abstract: Natural adrenaline is freed from arterenol by contacting an aqueous solution of their acid addition salts with an active methylene compound which may be a lower aliphatic ester of ethoxymethylene - malonic acid, ethoxymethylene-acetoacetic acid, ethoxymethylenecyanoacetic acid, or oxalacetic acid, or acetonylacetone.  The reaction is preferably carried out at 75-85 DEG C. in the presence of a water-miscible lower aliphatic alcohol, the active methylene compound being used in 45-50 per cent excess of that required to react with the arterenol present. The mixture is then made alkaline (to pH not above 9.5) when free adrenaline is precipitated.  The purification process may be repeated if necessary. The salts of the bases used at the beginning of the process are preferably derived from a weak acid such as acetic, but mineral acid salts may be used.  Examples show the use of various methylene compounds, ethyl ethoxymethylenemalonate being preferred.  If the product is coloured, it may be treated in acetic acid solution with sodium bisulphite and carbon.

Title: Improvements in and relating to clothers wringers
IPC: D06F45/18
Filed: 1940-07-18
Abstract: 539,098. Wringers. BRITISH THOMSONHOUSTON CO., Ltd. July 18, 1940, No. 11850. Convention date, July 18, 1939. [Class 138 (ii)] [Also in Group XXIV] The upper roll 27 is mounted in a control bar 40 adapted to engage in vertical slots in pressure members 46 drawn down by springs 50, and to be rocked into and out of engagement therewith for applying and releasing the pressure between the rolls and, if desired, connecting and releasing the drive, provision being made whereby the control bar is limited in its upward movement on release but can be detached from the wringer. Pressure is applied by rocking the control bar 40 to one side, Fig. 5, so that pins 43, 44 at each end thereof engage with a camming action against rolls 53, 56 mounted in recesses in the pressure members 46, mounted in the side styles 1, 2 thereby lifting these members clear of packing washers 51 and compressing the springs 50 whereby the upper roller 27 is pressed against the lower roller 26. In this movement of the control bar the pins 44 are carried beyond the line joining the centres of the rolls 56 and the roller 26 into stable position, and a lug 41 on the control bar engaging a slot 42 in a roll guard 32 mounted on the style 1 locks the guard whereby a sleeve 20 on the power transmission shaft 14 to the lower roller 26 is also rocked and, owing to the engagement of a cam plate 22 thereon with a fixed pin 24 on the wringer head 3, moved longitudinally to engage one of the crown wheels 12 on a splined sleeve 13 on the shaft 14 into engagement with the driving pinion 11 on the end of the vertical shaft 10 which transmits power from the washing machine drive. The wringer head 3 carrying the wringer base plate 3a and styles 1, 2 is mounted on a pillar 9 housing the shaft 10 and can be secured in various angular positions by a catch 7. The roll pressure is released and the drive arrested, by movement of the control bar to vertical position, an abutment 60 on the pressure member 46 serving as a fulcrum, whereby the fore required to move the pin 44 over its dead-centre position is reduced, and the lug 41 rocks the roll guard 32 and sleeve 20 to disengage the drive. The upper roll 27 is prevented from being thrown out of the machine on release of the pressure by inturned parts 68 on the pressure members : this roll and the control bar can, however be removed, after release of the pressure, by moving it endwise so that the pins 43, 44 can pass through a slot in the part 68. Specification 537,362 is referred to.

Title: Improvements in, or relating to, change-speed gears
IPC: B62M9/08
Filed: 1937-04-27
Abstract: 486,351. Variable speed gearing. CAHN, J. April 27, 1937, No. 11968. Convention date, March 31. [Class 80 (ii)] In expanding-wheel variable-speed gearing for cycles and similar vehicles, teeth 10, preferably of ratchet type to allow free-wheeling, on a sprocket &c. 9 adjustable radially of the cycle &c. axle 18 engage similar teeth on segments 45 simultaneously adjustable concentrically with the driven hub 24, with which thev turn. A one-to-one drive (in the position shown) and gearing-up ratios may thus be obtained. The sprocket wheel 9 is carried on ball-bearings by a disc 12, a slot 40 in which engages a pin 39 on a plate 38, adjustably secured to the cycle fork 25 so that manual adjustment of a cam lever 34 moves the sprocket radially to any of three positions. The segments 45 are pressed outwards by springs 52 and by a further elastic split ring and are pivoted on pins 46 with enlarged extensions which engage cam slots 47 in a toothed plate 48 and radial slots 49 in a plate 50 secured to the hub 24. On rotation of the cam lever 34 around the axle 18 by a link 37, an anchorpiece 35 at the same time engages and, provided the lever 34 is rotated more quickly than the toothed plate 48, rotates the said plate, the slots of which are so formed that the radial displacements of the sprocket and of the segments 45 are equal. At their inner positions the segments constitute a substantially continuous wheel. The teeth 10 may be replaced by substantially rectangular gaps, between which are arranged pairs of oppositely arranged ratchet teeth to engage corresponding teeth on opposite ends of the segments 45 to provide for reverse action for braking.
