Title: Film cassettes
IPC: G03B17/26
Filed: 1972-05-30
Abstract: 1395825 Film Cassettes AGFA-GEVAERT AG 30 May 1972 [28 May 1971] 25230/72 Heading G2E A cassette has a core which can rotate relative to the cassette, the core and cassette having an arrangement of stops and a flexible arm engageable therewith in pawl ratchet fashion so that the core can rotate in one direction only (i.e. film take-up), the arm being engageable from outside the camera through a light-trapped aperture to deflect it away from the stops so that the core can then be rotated in the reverse direction. As shown, the cassette has a wall portion 18, a removable lid 1, and an intermediate partition 2. A fixed core 3 has a rotatable core portion 7 thereon on which the film is taken up. Core 7 carries a resilient arm 11. A hollow cylindrical part 5 is fixed to the fixed core 3, and on its inner surface are formed a series of stepped portions 13. These constitute, with the bent-out end 12 of arm 11, a pawl and ratchet arrangement so that the core 7 can rotate clockwise, as seen in Fig. 2, but not anti-clockwise, i.e. in the film take-up direction only. Arm 11 has an upstanding wedge portion 14, which is accessible through an opening 10 in a recessed portion 9 of the cassette wall. A tool 15 having opposed projections 16 can be inserted into the recess 9, so that one of these projections enters through opening 10 and engages wedge 14, pressing it inwards. This flexes arm 11 inwards so that end 12 is drawn clear of the stepped portions 13, and thus core 7 is now free to rotate in the reverse direction also. Instead of the flexible arm 11 being on the rotatable core, and the stepped portions fixed, they can be reversed.
Patent GB-1107994-A (GB)
Title: Purification of solid carboxylic acids by a combined sublimation-leaching process
IPC: B01D7/02
Filed: 1965-06-15
Abstract: Solid carboxylic acids, e.g. terephthalic or isophthalic acid, are purified by vaporizing the impure acid and condensing the vapour by cooling it in contact with water or an organic liquid chosen so that a suspension of solid particles of the acid is obtained, while at least a major proportion of the impurities are dissolved in the water or organic liquid.  As shown, crude terephthalic acid (TPA), prepared by the partial oxidation of p-xylene, is charged as a dry powder through conduit 10 into hopper 12 where the crude acid is leached with hot acetic acid to remove some of the impurities.  The partially purified powdered TPA, leaving the bottom of hopper 12, is conveyed by a stream of acetic acid vapour (containing 4% of water-vapour) to a coil 26 in furnace 18 where the TPA is vaporized at 366 DEG  C. The vapour flows through insulated pipe 28 to tower down which is sprayed a shower of slurry, comprising liquid acetic acid ( + 4% H2O) and suspended particles of TPA, at a temperature of 82 DEG  C. to 110 DEG  C.  The vapour condenses in contact with the sprayed droplets, and the p-carboxybenzaldehyde impurity dissolves in the acetic acid. Part of the slurry withdrawn from the base of tower 30 is pumped back to the top of the tower via heat-exchanger 42, and the remainder is conducted through pipe 38 to rotary filter 46.  Part of the filtrate is pumped through pipe 20 to furnace-coil 22 where it vaporizes; and the vapour is used to <PICT:1107994/C2/1> entrain TPA from hopper 12. The remainder of the filtrate is discharged through pipe 56.  The TPA, scraped off the filter drum, is introduced by conveyer 60 into the top of dryer 62, where the particles are maintained in a fluidized condition by acetic acid vapour at 149 DEG  C., introduced through pipe 68.  The dry powder spills over weir 70, and is transported through conduit 72 to the hopper 74 of a second sublimation stage, which is carried out in the same manner as the first stage.  In the second stage, however, a vapour-filter is provided between the vaporization-coil and the condenser.  The condenser is desirably of glass-lined or ceramic construction, but stainless steel or aluminium may also be used.

Patent GB-462681-A (GB)
Title: Manufacture of sulphonic acids of 5-hydroxy-acenaphthene
IPC: C07C309/41
Filed: 1935-09-12
Abstract: Sulphonic acids of 5-hydroxyacenaphthene are made by heating a free 5-aminoacenaphthene sulphonic acid with water under pressure, if desired with the addition of an acid or alkali in such a small quantity and concentration that the initial pH value of the mixture at ordinary temperature is between 1 and 7.  The product may be removed before the reaction is finished, and the reaction continued. From the ammonium salts of the acids directly obtained, the other salts may be prepared.  In examples, the amino-acenaphthenesulphonic acid obtained by heating 5-aminoacenaphthene with 80 per cent sulphuric acid is heated with water in one and in two stages, and also with very dilute sulphuric acid or caustic soda in one stage; 5-amino-acenaphthene-6 (or 7- or 8-) sulphonic acid is treated similarly.  With other pH values, smaller yields are obtained. The salts of the hydroxy-acenaphthene sulphonic acids may be coupled to give azo-dyes.

IPC: B64D15/06
Filed: 1964-06-23
Abstract: 1,060,390. De-icing aircraft. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. Sept. 16, 1965 [June 23, 1964], No. 25933/64. Heading B7W. [Also in Division F1] Apparatus for de-icing aircraft comprises a small-bore tube, e.g. # inch diameter, embedded in a surface to be de-iced and connected in the circuit of an hydraulic control circuit operating at high pressure, e.g. 4000 p.s.i., whereby the heat generated by the flow of liquid through the tube is adequate to remove or prevent the formation of ice. A pump 25 delivers hydraulic oil through pipe 27 to operate flying controls and through priority valve 29 and pipe 28 to operate an undercarriage and, through a further priority valve 26 and solenoid operated valve 12, to supply oil to a small bore pipe or pipes 10 buried in a surface to be de-iced, the oil returning to a tank 32 through a pressuremaintaining valve 13, filter 36 and oil cooler 31, which are arranged in parallel with a thermostatically-controlled by-pass 33 and a pressure limiting by-pass 34. A switch 16 responsive to the differential pressure across valve 13 is connected to solenoid 22 through a normally closed manually operated switch 24 and a normally open manually operated switch 23. In operation, de-icing is initiated by closure of switch 23, the resulting presaure difference across valve 13 closing switch 16 to complete the circuit from voltage input 19 to solenoid 22, thereby permitting release of switch 23. De-icing is terminated by closure of switch 24. Should tube 10 be damaged, e.g. by impact, valves 12 and 13 would be operated automatically by a presiure-drop to isolate the de-icing part of the hydraulic circuit. Arrangements of tubes embedded in wing surfaces are described.
