Title: Improvements in or relating to transporter systems
IPC: B66B29/08
Filed: 1923-03-12
Abstract: 217,308. Lens, E. J. de. March 12, 1923. Transferring articles and persons to or from trains and other conveyances in motion. - The platform 1 is composed of a number of frames 2 each of which is jointed universally to a bogie 3 at each end and supports a floor 4 and a single wall 12 and roof 13. A ball 5, Fig. 4, at each end of a frame rests in a socket on the bogie and a plate 7 is provided at each side of the ball which rests on a block 8 having a ball-and-socket connection with a spring-supported plunger 9. The space between consecutive frames is bridged by a grate 16 composed of bars 17 each of which has at one end a boss 18 resting in a groove 19 on one frame and has the other end 20 slidably mounted in a recess in a platform 21 on the adjacent frame. Adjacent walls 12 are connected by a verticallycorrugated sheet-metal partition 22. Each bogie 3 has a rack 23, Fig. 5, which is engaged by an endless driving chain 24 actuated by a motor 29. When two platforms travelling in opposite directions are arranged side by side on steep gradients the racks engage non-driven chains similar to the chain 24 but geared together. At each station are entrance and exit platforms composed of a series of short belts 33, Fig. 8, arranged in line and driven at progressively increasing or decreasing speeds. The belts are carried by rollers 34 and pulleys 36 and are stretched by rollers 35. Each section comprises a number of parallel belts. Adjacent sections may be arranged as in Fig. 8, but the belts 44, 45 of adjacent sections are preferably mounted on pulleys 41, 43, Fig. 12, on the same shaft 37, the pulleys 41 being fast on the shaft and the pulleys 43 loose thereon. The gaps between the belts of any section are filled bv similar belts which are passed round the supporting rollers 34 and driven therefrom. Each shaft 37 is connected by gears to a shaft 51, Fig. 7. driven by a motor 52, the gears being so designed that each shaft is driven at an appropriate speed. In order that the speed of the last section may be the same as that of the. platform 1, a wheel 53, Fig. 8, with a resilient tyre bears on the platform and drives through gearing a differential device connected to the shaft 51. The gear ratios are such that the differential device is stationary when the speeds are the same. If the speeds are unequal, the movement of the differential actuates a governor which varies the speed of the motor. A partition 49, Fig. 7, separates all the sections of the entrance platform except the last three from the platform 1 and is of gradually increasing thickness so that a space may be cleared for the reception of new passengers. The space between the last two sections and the platform 1 is filled by a belt 54 driven at the same speed as the last section. A partition (not shown) arranged obliquely across the last section deflects passengers or goods on to the platform 1.

Filed: 1951-03-29
Abstract: 687,705. Filters. MULLER, J. March 29, 1951 [May 16, 1950], No. 7342/51. Class 46  In a filter cartridge comprising a pile of filter discs in which the even' and uneven .discs are clamped in pairs alternately by. outer and inner edges between outer and inner perforated spacer rings, each spacer ring, embodies two divergent elastically - yieldablelateral flanges symmetrical about the plane perpendicular. to the axis of the ring and directed towards the outside in the case of the outer ring and towards the inside in the case of the inner ring. A preferred shape for an inner ring is shown in Fig. 2; an outer ring has the same cross-section with the annuli directed outwardly. The discs and rings are compressed axially between annular end plates 7 and 8, Fig. 1, engaged behind in-turned and out-turned edges respectively of perforated cylinders 6 and 5 respectively and serving also to retain the pile of discs and rings in radial alignment. An out-turned edge 21 is provided on each face of each ring which edge penetrates into the material of the contiguous filter disc 1 &c. to ensure fluid-tightness. When the pile is assembled as in Fig. 1 the annuli of each ring are forced towards each other and by their resilience ensure fluid tightness between the contacting edges of each pair of discs. Further, by this movement of the annuli the diameter of the circular edges 21 of each inner ring becomes smaller and that of the corresponding edges of each outer ring becomes larger. Since these edges engage the discs 1 &c. the latter are automatically tensioned radially when the pile is assembled and compressed. Fig. 4 shows an alternate shape for the flanges.

Title: Improvements relating to modified phenol-aldehyde resins
Inventor: TURNER JOHN HARRY WALLICE
IPC: C08L61/10
Filed: 1953-03-26
Abstract: Oil soluble and oil-reactive phenol-aldehyde resins suitable for use in coating compositions, in the manufacture of linoleum &c., and in the production of sand cores, boat linings, &c, are obtained by condensing a monohydric phenol with an aldehyde in the presence of an acid catalyst, dehydrating the reaction mixture to yield an ungelled product free from aldehyde and heating the dehydrated resin in the presence of a Friedel Crafts halide catalyst and some free monohydric phenol in amount at least 5 per cent by weight of the total phenol employed in the process, to an elevated temperature until there is a substantial drop in the viscosity of the reaction mixture; the phenol used in the first stage must be an alkyl or aryl substituted phenol having at least one unsubstituted hydrogen atom in the positions ortho or para to the phenolic hydroxy group, or if phenol is used in the first stage, then such an aryl or alkyl substituted phenol must be used in the etherification stage.  Aldehydes containing up to 4C. atoms in the molecule may be used. 0.6-1.6 mols. aldehyde are employed per mol. phenol and reaction temperatures of about 100 DEG C. are specified.  The dehydration may be effected azeotropically in presence of a suitable solvent.  Friedel Crafts catalysts specified are boron trifluoride, hydrogen fluoride, aluminium chloride and fluorosulphonic acid.  The resins obtained may be further reacted with styrene, coumarone indene or highly conjugated oils, e.g. tung and oiticica oils.  The oils reactivity may be destroyed by neutralizing the resin with a base, e.g. sodium hydroxide, triethanolamine, morpholine, hexamine or metallic oxides; gelation of the resins is retarded by addition of hydroxyl containing solvents, e.g. alcohols.  In examples: (1) a condensation product containing 15 per cent free cresol is obtained by reacting 100 parts cresylic acid containing 52 per cent m-cresol with 80 parts 40 per cent formalin in the presence of 0.6 parts oxalic acid the resinous product is dehydrated at 125 DEG  C. under vacuum in presence of 0.2 per cent boron trifluoride/phenol complex until the viscosity falls; an oil-soluble resin of 90 DEG  C. melting point is obtained; (2) the initial resin obtained as in (1) is dehydrated azeotropically in xylol and the dry product refluxed at 110 DEG  C. in presence of aluminium chloride dissolved in di-ethyl benzene; (3) fluorosulphonic acid is employed as catalyst; (4) p-octyl phenol is employed in the second stage p-tertiary butyl phenol, p-tertiary amyl phenol and p-phenyl phenol may also be used.

Title: A continuous process for the roasting of arsenopyrites ores
IPC: C22B1/10
Filed: 1954-03-17
Abstract: In a continuous process for roasting arsenopyrites ores the ore is preheated in a separate stage, by direct heat exchange with a portion of the sulphur dioxide gases from the roasting stage, to a temperature e.g. 500-550 DEG C. such that arsenic compounds e.g. arsenic sulphide, are distilled off, but labile sulphur is not, the preheated ore is passed to the roasting stage and the remainder of the sulphur dioxide gases are recovered as arsenic-free gas.  The preheating and roasting stages are fluidized, and are both in the same vessel, in the apparatus described.  The arsenic-free gas is also passed in indirect heat exchange with the ore in the preheating stage and some may be recycled to the roasting stage.  The portion of the sulphur dioxide gases is cooled to condensate the arsenic compounds.

Abstract: 1,042,126. Control of A.C. motors. DANFOSS A.S. Feb. 25, 1964 [Feb. 25, 19631, No. 7856/64. Heading H2J. The starting winding of a split-phase motor is connected in series with a resistor having a marked positive temperature coefficient the resistor becoming heated during the starting period so that its resistance increases to limit the starting current to a low steady value. The resistor also affords protection for the starting winding if the rotor is stalled. The starting winding may be disconnected by a switch when the motor reaches full speed. The resistor can be associated with an additional heating winding in series with the main motor winding, or the resistor mounted on the motor housing which becomes warm during operation. The resistor may be connected in series with one capacitor and in parallel with another. Examples of the kind of resistor for use in the starting circuit are the iron-hydrogen type, or the type based on barium titanate and strontium or zircon with impurities such as lanthanum, yttrium, or cerium. In another form, the resistor comprises carbon granules in a gas-filled container having a flexible wall. Under heat, the gas expands to reduce the pressure on the carbon granules.
