Abstract: 1,095,318. Sodium phosphates. MARCHON PRODUCTS Ltd. July 8, 1965 [July 14, 1964], No. 28921/64. Heading C1A. Na metaphosphate is prepared by reacting NaCl and wet process phosphoric acid on a moving bed of metaphosphate particles at temperatures above 250‹ C. but below the m.pt. of the metaphosphate. The Na/P ratio of the reactants is from 0À85 1 to about 1 : 1. The acid may be crude 30% acid, or preferably purified to contain 3-9% SO 3  b.w. P 2 O 5  and concentrated to 48-65%. The NaCl may be ground to 100% pass 100 BSS and above 50% pass 300 BSS, and is added as a slurry in the acid. Carbon or carbohydrates may be added to reduce sulphate in the acid to SO 2 . The product usually consists of a mixture of soluble trimetaphosphate (STMP) and insoluble metaphosphate (ISMP). The STMP may be dissolved in water, separated from insolubles, and recovered by crystallization, or hydrolysed either to tripolyphosphate (in alkaline solution) or to orthophosphate (by heating at 115‹ C. in an NaH 2 PO 4  solution containing at least 30% P 2 O 5 ). Alternatively, the mixture of STMP and ISMP, or the ISMP after dissolving the STMP, may be treated thus: (a) heat with water at at least 150‹ C. (hydrolysis to orthophosphate and remove insoluble impurities, (b) heat to 500-580‹ C. (converts ISMP to STMP), dissolve in water, and remove insoluble impurities, or (c) fuse and cool rapidly to give polyphosphate glasses with Na/P ratios of 1, 1À02, 1À07, or 1À1, which may be adjusted with Na 2 CO 3 . The insoluble impurities (phosphates of heavy and alkaline earth metals) may be digested with H 2 PO 4 , H 2 SO 4  or NaOH. The reaction may be carried out with a stirred bed in a stationary container (favours ISMP) or continuously in a rotary drum with means for removing particles from the bed and returning them to another part, as described in 907900 (favours STMP).

Abstract: 1,238,643. Hydrostatic transmission. JOSEPH LUCAS (INDUSTRIES) Ltd. 3 Sept., 1968 [8 June, 1967], No: 26473/67. Heading F2D. In a hydrostatic transmission for a tractor wherein an engine-driven swash-plate" pump 5 supplies pressure liquid to a swash-plate motor 7 and a manual control lever 10 adjusts the stroke of the pump and/or motor, an override control for reducing the overall transmission ratio on overload comprises a servo 20 connected to the control lever 10 through a lostmotion coupling 18 and controlled by a valve 22 responsive to the pressure drop across an orifice 14 in the delivery of an engine-driven make-up pump 12. The pressure drop is applied to a spool 22a of the valve 22 and under normal running condition the pressure drop is sufficient to move the spool 22a left against the bias of a spring 23. Pressure liquid from the pump 12 is then supplied to both chambers of the servo 20 and its piston 19 moves left to permit free movement of the control lever 10. On overload the engine slows and the delivery from the pump 12 correspondingly reduced ,whereupon the pressure drop across the orifice 14 is reduced to permit the spring 23 to move the valve spool 22a right. The right chamber of the servo 20 is vented through the valve 22 and the piston 19 moves right to rotate the lever 10 clockwise for reduced output speed. The lever 10 is spring urged to a position of maximum output speed whilst depression of a pedal 11 rotates the lever 10 clockwise to reduce the output speed. The spring 23 is loaded by a piston 25 responsive to the position of the engine accelerator pedal 29 up to a limit determined by a stop 30. Below the limit a predetermined constant drop in engine speed causes change-over of the valve 22, whereas above the limit the valve 22 changes over when the engine speed falls below a predetermined value. The pump 12 supplies makeup liquid to the main circuit through a cooler 15 and filter 16 at a pressure determined by a relief valve 17.

A supply magazine for apparatus, e.g. a cigarette-making machine, requiring a supply of continuous web material comprises a rotatably mounted cylindrical housing 1; pins 17 for supporting a plurality of coils 8 to 12 of web material; a fixed turner bar 16 for guiding the web out of the housing along a path centre upon the rotational axis of the housing; a motor 7 for rotating the housing 1; and means 15 for controlling the motor 1 so as to avoid any substantial twist occurring in the web traversing said path. As shown, the coils are spliced together so that the web is drawn from the inside of alternate coils and from the outside of the remaining coils. Thus, in operation, as the web is taken from the housing at a constant rate it leaves each coil at an increasing radius, there being a sudden change from an outermost radius to an innermost radius as each coil becomes exhausted. To compensate for these changes so that the web remains untwisted as it leaves the housing, the speed of the motor 7 is controlled in a corrective manner so that the tangential speed at which the web leaves the respective coil is equal to the speed at which the web leaves the housing. To this end, the web passes through a slotted plate 15 which is so mounted as to tend to rotate in response to any twist in the web, any such rotation causing the speed of the motor 7 to vary by virtue of a control connection 18 which may include a field rheostat. In a modification (Fig. 2, not shown) the coils are spliced together alternately at their innermost and outermost ends, a central supporting spindle is provided, and a photo-electric device is arranged to control the speed of the motor 7.
