Abstract: 546,731. Folding fabrics. ADAMS & CO., Ltd., W. J., and ADAMS, W. H. G. April 28, 1941, No. 5432. [Class 42 ii)] A machine for folding or bunching narrow web material such as elastics, braid, webbing or tape in zig-zag form comprises two sets of fingers d, e normally disposed in staggered relation along parallel lines between which the web material may be drawn as shown in Fig. 3, and mechanism whereby the fingers of at least one set may in succession be caused to move through the spaces between the fingers of the opposed set, thereby gathering the material into a series of loops, Fig. 4, which are bound together to form the bundle or package required. The fixed fingers d are carried on two shafts c while the movable fingers e are pivoted on the upper shaft c and are provided with tension springs f, Fig. 1. The lower ends of the fingers e engage a stop bar g, which is recessed at g<SP>1</SP> to allow movement of the fingers until arrested by an abutment bar h. In operation all the movable fingers e are held back by the stop bar g and the material, clipped at k, Fig. 2, extended through the fixed and movable fingers as in Fig. 3. A crank g<SP>2</SP> is then engaged with a leading screw g<SP>3</SP> to traverse the stop bar g, thus releasing the movable fingers in succession so that each under its spring action draws a loop of the'material which is passed forward by a friction pulley i<SP>1</SP>. When all the fingers have been released the folded material is engaged by a recess l<SP>2</SP> in a clamp l slidable along a pivot bar. A sliding plate l<SP>3</SP> is moved to cover the recess l<SP>2</SP> and the tension in the loops eased by moving a cross bar j<SP>2</SP> against the fingers e. The material is then disengaged from the fingers by turning the clamp l about the pivot bar, the clamp is slid to the right to bring the projecting portions of the bundle against a stop bracket m after which elastic bands may be applied, the plate l<SP>3</SP> slid back and the finished bundle removed from the machine.

Title: Production of phosphorus
Inventor: WILSON ARTHUR
IPC: C01B25/02
Filed: 1963-02-11
Abstract: Ferrophosphorus is produced as a by-product in a process for the production of phosphorus wherein an aluminium phosphate is reacted with hydrogen at 700-1200 DEG C.ALSO:Phosphorus is produced by reacting an aluminum phosphate with hydrogen at 700-1200 DEG  C. Natural aluminium phosphates may be wavellite (Al3(PO4)2(OH)3.5H2O) or those containing calcium phosphate also, e.g. crandallite (CaAl3(PO4)2(OH)5.H2O) and/or millisite ((Na,K)CaAl6(PO4)4(CH)93H2O) which may be calcined and ground.  The aluminium phosphate may be mixed or coated with carbon, present in at least the stoichiometric amount, to react with water vapour to form carbon monoxide and additional hydrogen.  Graphite or coke of similar particle size to the phosphate may be mixed therewith before or during addition to the reaction vessel, or the mixture may be pre-pelleted. Alternatively, carbon may be coated on the phosphate by carbonization of hydrocarbon material, e.g. diesel fuel or natural gas, in a kiln or fluidized bed before or simultaneously with the reduction.  The reduction may be effected batchwise in a closed reactor with agitation under hydrogen pressure, or continuously in a fluidized or spouting bed. Where a fluidized bed is used, heating may be resistive by conduction between electrodes by carbon and two to six reactors in series may be used. The hydrogen may be preheated and reaction time may be 0.5-4 hours. The residue may be treated to isolate ferrophosphorus, alumina, and b -tri-calcium phosphate.  The first is density separated and the last two separated by solution, alumina in caustic alkali, and b -tri-calcium phosphate in sodium citrate.  The phosphorus is condensed from the vapours and carbon monoxide may be recycled or burnt.  Specifications 747,016 and 807,884 are referred to.

Title: Improvements in controls for forced flow, once through vapour generators
Inventor: ARBOUW JAN
IPC: F22G5/00
Filed: 1960-02-16
Abstract: 960,378. Regulating forced flow steam boilers. HOLLANDS INGENIEURS BUREAU HIBRO. Feb. 13, 1961 [Feb. 16, 1960], No. 5534/60. Heading F4A. A control device for a forced flow, once through boiler comprises a regulating apparatus motivated in response to the value of the amount of superheat, i.e. the difference in quantum of heat possessed by an amount of vapour at a temperature measured at a point in the superheat zone of the boiler and the heat possessed by the same amount of the same vapour at the saturated temperature, the value being derived from a measurement of the temperature of vapour at that point in combination with further measurement of the physical value of pressure and vapour flow or temperature and vapour flow within the boiler, the apparatus being adapted rapidly to vary the relation between liquid input and heat input to the boiler on change of load so that the output is adjusted, with only a small time delay, to the new conditions. Fig. 1 shows a boiler in which zones C-B containing liquid, B-A containing liquid and saturated vapour and A-D containing superheated vapour may be distinguished. A temperature probe 2 is inserted into the superheat zone and transmits signals to a control 10 also receiving signals representative of output flow from a transmitter 6. The combined signal is transmitted from the control 10 to the liquid input regulator 4. A change in load results in corresponding movement of the zone B-A causing a change in temperature of the probe, the resulting signal modified by the signal from 6 so that it bears a fixed relationship to output vapour flow, motivating the regulator 4 to adjust the boiler output and restore the zone B-A to its original position. The signal from the control 10 may be arranged to override the normal boiler control. Thus as shown in Fig. 4, a control device 10 receives signals from the probe 2 via a temperature transmitter 9, from an output pressure transmitter 7 and from an output flow transmitter 6 and passes a correcting and overriding signal to a control device 11 which also receives a signal from the output flow transmitter 6. The final control 12 receives a signal representing the desired input from the control 11 and a signal representing the actual input from the input flow transmitter 5 and the resultant signal obtained by comparison of these is used to regulate the liquid input control 4. A feedback signal passes from the input flow transmitter 5 to the control 12. In a modification (not shown), two probes are inserted close together into the boiler, one in the superheat zone and one in the adjacent zone, signals from the probes are compared in the transmitter 9 and a signal representing the temperature difference is fed into the control 10. In multi-tube boilers, a control as described above may be applied to each tube individually, regulators constituted by inlet chokes on all the tubes, or the inlet choke of one tube may be fixed and the control of this used to control the feed pumps.

Abstract: An adhesive composition is prepared by adding an organic di-isocyanate to a synthetic rubber, produced by the reaction of an alkylene dihalide and an alkali metal polysulphide and known under the name "Thiokol."  Methylene di-(p-phenylene isocyanate) is preferred, but any aliphatic or aromatic di-isocyanate, such as p-phenylene di-isocyanate, m-phenylene di-isocyanate, the diphenylene di-isocyanates, the ditoluylene di-isocyanates, the dimethyl phenylene di-isocyanates, the naphthalene di-isocyanates, hexamethylene di-isocyanate, the di-isocyanates of dioxane, ethylene di-(oxytrimethylene isocyanate), or the di-isocyanates of glycol ethers or dipropyl ethers may be employed.  The di-isocyanate added will normally amount up to 5 per cent of the weight of the total adhesive solids employed. Modifying-agents, such as resins, plasticizers, diluents, fillers, vulcanizing-agents, accelerators, or age-resistors may also be added.  The synthetic rubber and di-isocyanate may be applied to the surface in a one- or two-stage operation, but in the former case mixing of the ingredients should be effected only shortly before application.  The di-isocyanates are prepared by passing hydrogen chloride through a solution of the diamine in an organic solvent, passing phosgene through the suspension of the precipitate in the solvent, and then heating to the reflux temperature of the solvent.ALSO:An adhesive composition is prepared by adding an organic di-isocyanate to a synthetic rubber, produced by the reaction of an alkylene dihalide and an alkali metal polysulphide and known under the name "Thiokol" (Registered Trade Mark).

Filed: 1966-02-09
Abstract: 1,103,626. Photographic cameras with built in exposure meters. AGFA - GEVAERT A. G. Feb.9, 1966 [Feb.13, 1965], No.5672/66. Heading G2A. A photographic camera having means, including an exposure meter, for automatically setting the shutter speed and diaphragm aperture, is further provided with an exploratory can 32 which senses the position of a movable index member 34 of the exposure meter; a transmission ring 20 rotatably mounted in the shutter housing of the camera the degree of rotation thereof depending on the movement of the cam 32; a rotatable diaphragm setting ring 2 spring-loaded into one end position and movable into another end position by means of a lost motion coupling provided between the rings 2, 20; manual setting means 12-16 for varying the position of a coupling member 22 prior to its engaging a fixed pin 23 on the ring 2, thereby varying the degree of lost motion. After the member 22 and pin 23 have made contact, further rotation of the ring 20 before the cam 32 senses the index member 34 causes the diaphragm blades 4 (only one shown) mounted on a fixed ring 1 to close and the shutter speed to be curtailed by retarding mechanism, of which only the control pin 8 is shown. To account for a correction factor the ring 12 is manually set against the scale 15, thereby varying the position of the cam surface 16, and hence of the coupling member 22 carried by a lever 18, a pin 17 of which follows the cam surface 16. The index member 34 is carried by a moving coil galvanometer 35, which is rotated to a greater or lesser extent in the direction b on insertion of a film cartridge 46 carrying indicia 45 the position of which varies depending on the sensitivity of the film in the cartridge. The galvanometer is connected with a photo-sensitive receiver 48. In another embodiment, Fig.2 (not shown), the diaphragm setting ring 2 is no longer spring- loaded, but a spring (50) is provided between the pin (23) and the transmission ring (20). The ring (12') is provided with a control pointer (51) and a toothed locking section (52) whereby the ring (12') may be locked to a ring (54) carrying a scale (53) at which the pointer (51) is set. The ring (54) is then set against a second scale (62), hence two correction factors can be accounted for. In a further embodiment, Fig. 3 (not shown), the arrangement is described for a camera having two movable diaphragm rings (70, 71) and in which a modification of a setting ring (99) is made to enable flash and bulb exposures to be effected.
