The expression "fine grain" is used to define a substantially homogeneous particulate material which when used in the method of the invention gives a product which is non- sticky and free-flowing. The "short tubular reactor" has a tubular reaction chamber of only sufficient length in relation to its capacity to enable a thorough mixing of the reactants and optimum build up of pressure before ejection thereof, and which is not so long, in relation to the normal throughput of the mixture, to enable the reactions to be completed or substantially completed before ejection of the mixture. The reactor (Fig. 2) may have three sections arranged one after the other, these being a mixing chamber 55, a reaction or pressure chamber 56 and discharger tube 53. The reactant feed lines 51, 52 may be connected tangentially with the mixing chamber. A rod 54 may be arranged at the rear of the reactor for use if the reactor becomes clogged. Apparatus (Fig. 1) for carrying out the process comprises a housing 7, defining a gas-filled free-fall chamber, the short tubular reactor 5, open at one end and having discharge means 53 (Fig. 2) for discharging the reacting mixture into the top of the chamber, and means 8 at the base of the chamber for collecting the resultant reaction product after its discharge from the reactor, the reactor having a pair of feed lines 51, 52 for the supply of calcium carbonate suspension and phosphoric acid respectively and the collecting means including a reaction product discharging device 10 for discharging the product from the chamber.

Abstract: 1531881 Door operating devices AUTOMOBILES PEUGEOT 15 March 1976 [7 May 1975] 10221/76 Heading E2M In a device for avoiding accidents when closing a movable panel 1 e.g. a sliding roof, an electric motor 2 is adapted to drive the panel 1 between an open and a closed position through a two-way reversing switch 3, a first electromagnetic relay 7 having a coil 6 connected in series with the motor 2 to cut off the supply to the latter when the torque generated by the motor during the displacement of the panel exceeds a pre-determined value. An end of travel switch 12 is provided inhibiting the relay 7 when the panel 1 is in the immediate vicinity of its closed position. The first electromagnetic relay 7 is connected in series with a second relay 9 and a switch 8 actuated by the second relay such that the cutting off of the supply to the coil 6 causes a blade switch 11 in the first relay 7 to return to its open state. If an obstacle opposes the displacement of the movable element 1, the supply current to the motor increases and there is a corresponding increase in the current in the coil 6 of the first relay 7. When the supply current reaches a predetermined value, the blade switch 11 is closed and current is supplied to the second relay 9. The switch 8 is actuated and causes the supply circuit of the motor 2 to be cut off and the motor 2 stops. The reversing switch 3 has three positions (a) that shown in Figure 1 (a neutral position), (b) that shown in Figure 2 (an open position) and (c) that shown in Figure 3 (a closed position).
