Patent GB-757866-A (GB)
Title: Improvements in or relating to purifying sugar solutions
IPC: C13B20/14
Filed: 1954-11-10
Abstract: Colour bodies and other dissolved impurities are removed from sugar solutions at temperatures of 130 DEG -210 DEG F. by passage through a porous quaternary ammonium anion exchange resin in the salt form, especially chloride.  The preferred concentrations and temperatures are 40 DEG  to about 70 DEG  Brix and 140 DEG -190 DEG F.  The resin may be regenerated by treating with a solution of a water soluble chloride or hydrochloric acid and subsequently with a solution of a mild oxidizing agent to remove the remaining adsorbed colour bodies; solutions of sodium chloride and sodium hypochlorite or hydrogen peroxide are preferred.  When the amounts of colour bodies adsorbed are high compared with those of other anions adsorbed, the exhausted resin may first be treated with a hot solution containing about 1-10 per cent mineral acid or salt thereof, then with 0,25-5 per cent solution of hypochlorite or hydrogen peroxide at ambient temperature and then again with a hot solution of the mineral acid or salt.  When the amount of adsorbed colour bodies is comparatively low, the resin may be regenerated a number of times with only the acid or salt solution and only occasionally with the mild oxidizing agent. Specifications 654,706 [Group IV(a)], 670,348 and 670,438 are referred to.

Fig. 3 shows the output Ia of the winding 1 plotted against the ampere-turns Nc, Ic of the control windings 2, 4. No current passes to the emitter, however, unless Ia exceeds the constant current Io = Vo/r as illustrated by the line S2, S1. Fig. 5 illustrates at 6 the consequent collector current. This is smoothed by condenser Ca and passed to the load resistor R. Saturation occurs at a value Is = U1/R to give a substantially constant output. The circuit can be rendered bi-stable by the inclusion of a positive feedback winding 3 in series with the load R. Specification 791,372 is referred to.

Title: Improvements relating to the production of fluid-tight packages
IPC: B31B70/00
Filed: 1956-10-26
Abstract: 845,761. Bags; packaging. BERGHGRACHT, M. Oct. 26, 1956 [Oct. 28, 1955], No. 32793/56. Classes 94(1) and 94(2). A bag is formed from a single unscored blank 1 by folding it round a mandrel 5 moveable about a pivot 6 at right angles to its longitudinal axis to press the blank onto its end after its having been applied to three side faces, the mandrel incorporating suction means to retain the blank. The blank is coated with thermoplastic lacquer and may be of laminated material. The blank 1 is applied to a side face of the horizontal mandrel 5 by a plate 4 which then withdraws, the blank being retained by suction through apertures 7. The mandrel pivots downwards causing plates 15, 151 to wipe the blank against opposite sides, and a plate 16 to fold it onto the mandrel end. Members 17 (only one shown), move down on opposite sides of the mandrel, Fig. 4, to form end folds, and plates 18 rise to wipe the folds against the mandrel sides. These sides are recessed at 11, 11<SP>1</SP> to accommodate the thickness of the end folds. A member 20 rises to fold the blank against the remaining mandrel sides, Fig. 6, and flaps 21, 22 pivot through 180 degrees to complete the bag side folds. These folds are secured by heated presses, Fig. 8 (not shown), and the bag, after impression of closure fold lines on its upper end by means, (not shown), is ejected by pressure air passing a valve 10 in the mandrel end. The closure is initiated by a bar 26 entering cutouts 3, 31 and descending to fold parts 27, 271 beneath outwards, members 29, 291 folding flaps 28, 281 inwards into overlapping relation. The bar remains in place while a heated presser seals the overlap, and then withdraws leaving openings through which the bag may be filled with powder, liquid, or if previously filled, with preservation gas. The parts 27, 271 may be nipped between hot sealers, Fig. 15 (not shown), then turned by folders 33, 331 onto the bag top.

Abstract: 358,320. Weighing-apparatus fitted to conveyers. BROWN, S. C., 40, Gloucester Road, North Harrow, Middlesex. Nov. 1, 1930, No. 32874. [Class 143.] In an autom a t i c weightindicating and d weight -totalizing and recording mechanism, such as that described in Specification 3351/09, [Class 143, Weighing- apparatus], applied to a conveyer of the reversing t y p e means are provided for automatically maintaining the same direction of rotation of the weigher operating-cams when the direction of travel of the conveyer is reversed, and means for automatically segregating, upon two separate weight recorders, the totalized weight records of goods carried in one direction from the totalized weight records of goods carried in the opposite direction. The pulley 3, Fig. 1, previously employed to actuate the cam shaft 21, Fig. 3, controlling the usual measuring quadrant and counter (not shown) is now connected by a chain to an intermediate shaft 25 carrying two ratchet wheels 27, 28 and two loose bevel wheels 23, 24 engaging a bevel wheel 22 on the cam shaft. Pawls carried by the loose bevel wheels 23, 24 engage the ratchet wheels in opposite directions and consequently the direction of rotation of the cam shaft is unaffected by a change in the direction of travel of the conveyer. When the direction of travel of the conveyer is reversed, the change in the direction of rotation of the pulley 3 displaces a pulley 16 thereby throwing over a series of levers 14, 13, 9 so as to change the drive of a clutch barrel 7 from one counter 5 or 5a to the other counter, the clutch barrel being geared to the totalizing mechanism. In modifications, the lever 9 is thrown over by a solenoid and switch, controlled by the lever 14, or is thrown over by levers 18, 19, Fig. 5, actuated by the direct contact of a roller 16 with the conveyer.

[Also in Divisions G2-G3, H1 and H4] Apparatus for producing an electric charge image from an input electrical signal train, e.g. a teleprinter output, computer print-out signal or the output from a picture telegraph transmitter, comprises a pattern of elemental capacitors having a common dielectric layer, a plurality of transistor switches, one connected to each capacitor, and means for sequentially charging the capacitors through the switches from the signal train, the capacitors and switches being incorporated in a thin film structure. As shown in Fig. 1, each capacitor comprises an electrode 3 and the portions therebelow of a dielectric 1 and an earthed metal plate 2, the capacitor being connected to the output S of a field effect transistor 4 whose inputs D and G are respectively connected to the intersections of interconnectors R, C, which form a rectangular array, as shown in Fig. 2. Each capacitor P is charged in sequence when its corresponding transistor F is made conductive by the simultaneous occurrence of the signal train on input C and a positive potential on input R. Input C is connected to the output of a semi-conductor AND gate 5, having one input connected to the signal train from source V and the other input connected to a shift register 6 driven by a master oscillator 7. Input R is derived from an AND gate 8 having inputs connected to a D.C. source and a second shift register 9, driven by oscillator 7 via a frequency divider 10. The AND gates may be structurally separate, or incorporated in the thin film. The charge image is developed by dusting with a toner powder, either directly on to the insulating layer 1, or on to an overlying protective insulating layer.
