Title: Improvements in or relating to phosphatic fertilizers
IPC: C05B11/10
Filed: 1947-05-19
Abstract: Double or triple superphosphate is produced by adding finely ground phosphate rock to aqueous phosphoric acid solution of a strength of 30-37 DEG  B<\>ae, which has been preheated to a temperature between 90-100 DEG  C., the temperature being maintained during mixing so that the reaction occurs in the liquid phase and is completed in 20 minutes, the product then being dried. Nitrogeneous or potash fertilisers may be added to the reaction product after reaction is completed but before drying in order to produce a granular compound fertiliser.  Specification 1435/98, [Class 1], and U.S.A. Specification 1,869,879 are referred to.ALSO:A compound phosphatic fertilizer is prepared by adding nitrogenous and/or potash fertilizers such as ammonium sulphate or potassium chloride to a superphosphate prepared by adding finely ground phosphate rock to an aqueous phosphoric acid solution of strength between 30-37 DEG Be which has been preheated to 90-100 DEG  C., the temperature being maintained during mixing and the reaction being completed in 20 minutes.  The additional fertilizers are preferably added after the reaction is completed and before drying.  According to an example 100 kilograms of Morocco phosphate are added to 161 litres of phosphoric acid containing 475 grams P2O5 per litre heated to 90 DEG  C., and mixed for 10 minutes.  The reaction mass is transferred to another mixer and 175 kilograms of ammonium sulphate are added and mixing continued for 2 minutes.  195 kilograms of muriate of potash are then added and after a further two minutes the product is transferred to a granulator and dried.  Specification 1435/98, [Class 1], and U.S.A. Specification 1,869,879 are referred to.

Title: Improvements in or relating to magnetic core switching arrays
IPC: H03K17/81
Filed: 1962-04-13
Abstract: 981,906. Circuits enploying bi-stable magnetic elements. INTERNATIONAL BUSI. NESS MACHINES CORPORATION. April 13, 1962 [April 13, 1961; April 26, 1961], No. 14360/62. Heading H3B. To prevent spurious outputs due to partial switching of unselected cores in a co-ordinate magnetic switch, the output windings from the cores are connected in series with their respective loads, and the group of circuits so formed are connected in parallel, the parallel circuits either having a common return path which includes an inductance, Figs. 1, 4 and 7, or do not have a return path provided, Fig. 5. One row only of switching magnetic cores 10a-10n is shown in full lines in Fig. 1 and only one of the column wires 14. When the column and row wires 12, 14 are coincidently energized, only one core such as 10b is fully switched and an output pulse is induced in a single output wire 16b. This pulse passes through a load 18c such as a row or column 18 of a matrix memory, and returns through the parallel paths provided by output wires 16a and 16c to 16n and their loads 18, and the common return path 23 including inductance 24. The pulse returning through the unselected output circuits suppresses the spurious outputs due to partial switching of the unselected cores in the row. The inductance 24 is matched to the inductance of the partially switched cores, and for the period during which spurious voltages are induced constitutes a further parallel path of equivalent impedance. When however the partial switching of the unselected cores terminates, the remainder of the output pulse attains a steady value and the inductance 24 no longer restricts the flow of current through path 23. In a modification, Fig. 4, the inductance 24 is replaced by a switch core 32 not provided with an output load or column winding. A complete switching matrix of nine cores 10a to 10i is shown in Fig. 7, the common return path for a fully switched core output comprising wires 26, 28 and associated inductances 24. No common return path is provided in the arrangement shown in Fig. 5 which has the disadvantage that the initially high path impedance to the output pulse is maintained for the whole of its duration.

Abstract: 815,923. Bearings. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 16, 1957 [May 9, 1956], No. 14487/56. Class 12 (1). [Also in Group XXVI] A shaft 18, which penetrates a partition 13 and at one side carries a working member 19, such as a pump or compressor impeller, and at the other is driven by an electric motor 20, is sealed where it passes through the partition by feeding a barrier and lubricating gas (e.g. nitrogen) through a sleeve journal bearing 16; gas is fed to the bearing through a coiled tube 22 at a suitable, adjustable pressure. The hollow shaft is mounted within a cylindrical casing 10 on journal bearings 16, 23, each being carried by a flexible diaphragm 15, 24. Gas leaking through the bearing 16 enters a recess 49 at its outer end. A boss 34, which closes the end of the shaft, has a coaxial portion 35 of reduced diameter on which a thrust-plate 36 is tightly fitted to rotate with the shaft.

Title: Improvements relating to telephone systems
IPC: H04Q3/62
Filed: 1940-09-30
Abstract: 542,455. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and CLAY, D. L. Sept. 30, 1940, No. 14720. [Class 40 (iv)] A privileged subscriber who is leaving his telephone or who does not wish to be disturbed may set apparatus associated with his line at the exchange (1) to direct incoming calls to the line of another subscriber, (2) to give a distinctive tone or announcement to a caller who may then by further dialling complete the call to the privileged subscriber's own line or to another line, or (3) to give NU tone. The arrangement does not interfere with the use of the line for outgoing calls. The apparatus is connected to the final selector outlets allotted to the privileged subscriber's number and includes a rotary switch RR giving access to his line and to other lines to which calls may be transferred. For the purpose of setting the apparatus, it may be reached by dialling a special number from any substation, whereupon the switch RR may be controlled by a further train of impulses. If the privileged subscriber is situated near the exchange however, the switch RR may be controlled by marking relays operated from a set of keys. Assuming that the apparatus is seized in response to a special number, line relay A energizes over a preceding loop, the switch RR if off-normal goes home, and dialling tone is returned. Impulses are repeated by A to step the switch RR and to operate relays P, Q in turn, the arrangement being such that relay Q remains up when the switch is set to an odd position. With the switch in an even position, an incoming call is extended directly either to the privileged subscriber's line in position 0 (normal), to another line in position 2, 4, 6 or 8, or to a source of NU tone in position 10. The odd positions are wired to the same lines, but since relay Q is up, an incoming call energizes line relay AA and a distinctive tone is given over wire RT. If the caller decides to persist in the call, the dialling of any digit results in the operation of relays E, ON, whereupon the line is tested by relay H and ringing or busy signalling takes place in the usual manner, switching being performed by ring-trip relay TR upon reply. The apparatus may be modified so that all calls or all except those extended over the normal position of the switch are held in suspense by connecting the final selector outlets directly to relay AA or over make contacts of an off-normal relay. The allocation of two positions of the switch to each line is then unnecessary. The apparatus can be added at an existing exchange by means of connections at the intermediate distributing frame.
