Either the bores are coated with epoxy resin, or the plate is made thereof. Preferably, the plate is of mild or stainless steel with tubes of these materials, either integral or removable, forming the bores, the tubes being coated internally with epoxy resin and, preferably, coated externally with material which will not readily be wetted by the material being prilled. The external coating may be, e.g. a fluorocarbon, a mixture of ceramic and fluorocarbon, or a silicone rubber and may also be applied to the plate surface between the tubes. Alternatively, the plate may be of polytetrafluoroethylene in which case it need not be coated. Preferably, the tubes taper to a sharp nozzle rim (Fig. 2, not shown), and project below the plate. Suitable dimensions for all components are given. The epoxy resin coating is obtained by applying a prepolymer and curing in situ by catalyst and/or hardener of which examples are given. The epoxy resin prepolymer is preferably derived from epichlorhydrin and a bisphenol such as diphenylol methane, diphenylol propane or di-(dichlorophenylol)propane, a formula for the preferred type of bisphenol being given.  The construction of a heated prilling head embodying such a distributor plate (Fig. 1, not shown), is described together with its use for prilling melts of ammonium nitrate, urea, ammonium nitrate/ammonium phosphate; mixtures of urea and potassium chloride or of ammonium nitrate and ammonium sulphate. The prilling tower may have a flexible lining of p.v.c. coated nylon or canvas or of p.v.c. or polyethylene sheeting. The molten material may have pressure waves induced in it by providing a transverse plate just above the distributor and reciprocating the former at 50 to 120 c.p.s. The droplets may fall through an upward stream of gas which may contain dust of the material being prilled, or of another fertilizer, or of some other material of which a large number of examples is given. A second fluidized bed of larger solid particles may be formed below this dust zone; these particles being of the same or different materials and formed either in the same or a separate gas stream.

Abstract: 753,400. Alternators. SIEMENS-SCHUCKERTWERKE AKT.-GES. May 12, 1954 [May 12, 1953], No. 13930/54. Class 35. A synchronous generator is excited from its terminals through rectifiers connected in series with condensers, the condensers being shunted by choking coils which saturate at the working voltage of the machine. The stator field winding of the generator 1 is excited through rectifiers 2 from the secondary windings of a transformer 3, whose primary windings are connected between the lines and, at tapping points, to the load terminals of the machine. The other ends of the primary windings of the transformer are connected to the delta-connected condensers 4 so that these condensers are fed at the supply voltage. In this way, the secondary winding currents are compounded of the load current in the top part of the primary windings and condenser currents in the whole of each primary winding. A choking coil 5, which saturates at the working voltage is connected in each phase in parallel with the condenser 4, the effect of saturation being made more definite by means of condensers 6. The field is composed of three phase windings connected so that two parallel connected phases are in series with the third phase.

In an automatic telephone system metering information in respect of calls made by the subscribers of each exchange is stored in the exchange concerned and is subsequently transferred in bulk to a central store, the information in this central store being used to assess the charges for all the subscribers. At each exchange one core of a ferrite core matrix is allocated to each subscriber, which core is triggered by the occurrence of a metering pulse on the corresponding subscriber's metering lead. The cores are continuously scanned under control of a pulse-controlled scanner and the identity of lines metered are transferred, one at a time, to a temporary store. A magnetic drum having a track for each subscriber in the system is situated at the central exchange and in respect of the lines of that exchange the total of unit calls recorded in respect of a subscriber is transferred from the drum to an adder each time that subscriber is metered. One is added to this number and the new total is reinserted on the drum. In the case of subscribers of the other exchanges, the identity of a metered subscriber is recorded on a magnetic tape or the like in the exchange concerned. Subsequently, at some convenient time, the information on these tapes is offered to the central exchange equipment in like manner to that in respect of central exchange subscribers and the totals recorded on the drum are altered accordingly.
