Title: Process for the continuous manufacture of superphosphate, and apparatus for carrying out said process
IPC: C05B1/02
Filed: 1954-05-14
Abstract: <PICT:0765481/III/1> Pulverulent superphosphate is prepared by reacting ground phosphorite and sulphuric acid whilst subjecting the reactants to a slow pressing and kneading action such as not a retard the conversion of the reactants from the liquid to the solid state and for a time sufficient to release the gaseous reaction products, removing water vapour together with the gaseous reaction products until the mixture has a temperature from 80 DEG  to 90 DEG C. and a moisture content of 18 to 20 per cent by weight, and thereafter cooling the reaction mixture to 50 DEG  to 60 DEG C. whilst transfering it to storage, and finally storing the superphosphate at a temperature of 40 DEG  to 45 DEG C. for a period sufficient for the attainment of equilibrium.  The equilibrium reactions, which occur to about 75 per cent during the pressing and kneading action, are defined as being the reaction of phosphoric acid on tricalcium phosphate to form mono and di-calcium phosphates, and the reaction of phosphoric acid on dicalcium phosphate to form mono calcium phosphate.  As shown in the Figure, finely ground phosphate is fed through a weight feeder 1 to a horizontal kneader mixer 4 to which sulphuric acid is also fed from tank 2 through a polyvinyl chloride volumetric measuring apparatus 3. The mixer 4 lined with acid proof material contains one or more generally two shafts rotating in opposite directions at speeds from 25 to 50 r.p.m., the shafts being provided with helicoidal blades.  After passing through the mixer 4 the reactants in semi-solid state are passed up a conveyer 5 to storage, whilst reaction gases are withdrawn from the conveyer 5 and the mixer 4 by an aspirating fan 8.  The reaction mass normally remains in the mixer for 2 to 10 minutes during which time the hydrogen fluoride and silicon tetrafluoride gases develop completely and are withdrawn to an absorption plant.

Filed: 1974-04-01
Abstract: 1426693 Brake boosters BENDIX CORP 1 April 1974 [23 April 1973] 14298/74 Heading F2F In an hydraulic power boost mechanism for a vehicle braking system of the type having a housing 18 with a piston 32 reciprocally positioned therein and dividing the housing into an exhaust chamber 36 and a power chamber 34, the piston is provided with a longitudinal bore 68 and a control valve means 70 in the bore consisting of a spool valve 72 having a release position in which the power chamber is communicated to the exhaust chamber and an applied position in which the power chamber is connected to an hydraulic fluid pressure source for developing a boost pressure in the power chamber for driving the piston. The spool valve includes a central cavity 88 communicating the power chamber with the fluid pressure source when the spool valve is in the applied position, a pressure regulating device 120 being arranged in the central cavity so that, in the applied position of the spool valve, when the boost pressure is below said predetermined value, the power chamber is open to the pressure source and when the boost pressure is equal to said predetermined value, the power chamber is closed to the pressure source. As shown, with the pump 10 in operation and the brake pedal 104 released hydraulic fluid flows into an inlet port 20, groove 58, radial passage 78, recesses 74, 82 and 76, radial passage 80, groove 60 and outlet port 22 from which the fluid returns to the pump via steering gear mechanism. The power chamber 34 is connected to the exhaust port 24 through channel 95 in the spool valve, recesses 92, 94, radial passage 96, passageway 98 in the piston 32 and the exhaust chamber 26. Actuation of the pedal 104 moves the spool valve to the left, as seen in the Figure, closing, when shoulder 93 co-operates with shoulder 97, the channel 95 which communicates the power chamber 34 with the exhaust port and opening of the chamber to inlet port 20 through the T- slot connection 102, cavity 88 of the spool valve, and passages including the annular recesses 86, 82. Upon further depression of the pedal the overlap between recesses 82, 86 increases to admit more fluid to the chamber 34 until the boost pressure acting in the chamber and on the ends of the stepped plunger 128 attains a predetermined value, the net force of which overcomes the spring 134 causing the plunger to shift towards a seat 122 thereby restricting further boost pressure build up. Upon engagement between the seat and plunger, further pedal movement shifts the spool valve 72 to increase the pressure in the cavity 88 and this has no effect on the pressure in the chamber 34. The predetermined boost pressure acting in the chamber 34 may be pre-selected by adjusting the seat 122 with respect to the end 127 of the plunger 128 whereby the boost pressure may be selectively limited to a value which will keep the master cylinder line pressure below brake line burst pressure.

Abstract: 1389611 Multiplex pulse code signalling FUJITSU Ltd 27 March 1972 [27 March 1971] 14319/72 Heading H4L In a time division multiple access communication system comprising a plurality of stations communicating via channels allotted on a demand assignment basis, some of the channels are arranged for use with digital speech interpolation (DSI) and the number of channels available for DSI is increased when the traffic on the remaining channels is low. The arrangement is described in relation to a satellite communication system, Fig. 1, in which audio signals from a transmission trunk TRK are converted to PCM at PCM-COD and fed in time division multiplex via a DSI control unit DSIU-T to a unit CRU-T which converts the signals to the signal speed in the satellite circuits. The signals are then converted into a burst at BSU-T and the normal control signals for synchronization &e. are added, the burst signals being PSK modulated and transmitted to the satellite. Signals received from the satellite are PSK demodulated and supplied to BSU-R in which the control signals are extracted from the burst, the timing of the transmitted burst being regulated in dependence on phase relationships with the received bursts. The communication signals are supplied to CRU-R which converts the signal speed to that of the PCM decoder PCM-DEC, the DS1 control unit DS1U-R for the receiving section ensuring that the signals are allotted to the correct channels. A stored programme central processing unit CPU performs the demand assignment control via unit T1U. As described some of the channels operate under DSI conditions and others do not the arrangement being varied according to traffic conditions. In the transmitting section a reversible counter detects whether speech is taking place or not and a first storage unit stores the counted values for each channel and also stores satellite channel numbers which are used with DSI. A second storage unit stores information indicating station channels as being used or not used for DSI and also stores address information of the station channels. The information in the first storage unit is read out on the basis of the information stored in the second unit and a satellite channel is re-allocated to another station channel if the count for a station channel falls below a predetermined level by re-writing the information stored at the relevant address in the second storage unit.
